     Holders of Preferred Securities will be entitled to receive preferential
cumulative cash distributions accruing from the date of original issuance and
payable quarterly in arrears on the last day of March, June, September and
December of each year, commencing March 31, 1997, at the annual rate of      %
of the Liquidation Amount of $25 per Preferred Securities ("Distributions"). The
Company has the right to defer payment of interest on the Subordinated
Debentures at any time or from time to time for a period not to exceed 20
consecutive quarters with respect to each deferral period (each, an "Extension
Period"), provided that no Extension Period may extend beyond the Stated
Maturity of the Subordinated Debentures. Upon the termination of any such
Extension Period and the payment of all amounts then due, the Company may elect
to begin a new Extension Period subject to the requirements set forth herein. If
interest payments on the Subordinated Debentures are so deferred, Distributions
on the Preferred Securities will also be deferred, and the Company will not be
permitted, subject to certain exceptions described herein, to declare or pay any
cash distributions with respect to its capital stock or debt securities that
rank pari passu with or junior to the Subordinated Debentures. During an
Extension Period, interest on the Subordinated Debentures will continue to
accrue (and the amount of Distributions to which holders of the Preferred
Securities are entitled will accumulate) at the rate of      % per annum,
compounded quarterly, and holders of the Preferred Securities will be required
to accrue interest income for United States federal income tax purposes. See
"Description of Subordinated Debentures -- Option to Extend Interest Payment
Period," and "Certain Federal Income Tax Consequences -- Potential Extension of
Interest Payment Period and Original Issue Discount."
    
 
   
     The Company has, through the Guarantee, Trust Agreement, Subordinated
Debentures, Indenture and the Expense Agreement (each as defined herein), taken
together, fully, irrevocably and unconditionally guaranteed all of IBC Capital's
obligations under the Preferred Securities. See "Relationship Among the
Preferred Securities, the Subordinated Debentures and the Guarantee -- Full and
Unconditional Guarantee." The Guarantee of the Company guarantees the payment of
Distributions and payments on liquidation or redemption of the Preferred
Securities, but only in each case to the extent of funds held by IBC Capital, as
described herein. See "Description of Guarantee." If the Company does not make
interest payments on the Subordinated Debentures held by IBC Capital, IBC
Capital will have insufficient funds to pay Distributions on the Preferred
Securities. The Guarantee does not cover payments of Distributions when IBC
Capital does not have sufficient funds to pay such Distributions. The
obligations of the Company under the Guarantee and the Preferred Securities are
subordinate and junior in right of payment to all Senior Debt, Subordinated Debt
and, under certain circumstances, Additional Senior Obligations (each as defined
in "Description of Subordinated Debentures -- Subordination") of the Company.
    
 
   
     The Preferred Securities are subject to mandatory redemption, in whole or
in part, upon repayment of the Subordinated Debentures at maturity or their
earlier redemption. Subject to Federal Reserve approval, if then required, the
Subordinated Debentures are redeemable prior to maturity at the option of the
Company (1) on or after             , 2001, in whole at any time or in part from
time to time, or (2) at any time, in whole (but not in part), upon the
occurrence and during the continuance of a Tax Event or an Investment Company
Event (as defined herein), in each case at a redemption price equal to the
accrued and unpaid interest on the Subordinated Debentures so redeemed to the

THE COMPANY'S APPROACH TO COMMUNITY BANKING
 
     The Company attributes its past success to the consistent application of
community banking practices in predominantly rural and suburban markets. The
Company's operating philosophy seeks to preserve those elements of traditional
community banking which management believes create a competitive advantage in
the markets in which it operates. Accordingly, the Banks emphasize personal
service and customer recognition, prompt response to customer needs,
convenience, continuity of personnel and management, and commitment to and
participation in the community.
 
     DECENTRALIZED MANAGEMENT. The Company vests management of the Banks with
the authority to make local pricing and credit decisions to better anticipate
customer needs, respond to customer demands, and identify profitable
opportunities within their respective markets. While management of each of the
Banks is granted the authority to make decisions for its local operations, it is
also held accountable for its performance.
 
   
     CORPORATE ADMINISTRATIVE AND SUPPORT SERVICES. To complement the Company's
decentralized management structure and preserve its community banking practices
within an expanding franchise, the Company's corporate service departments
provide a variety of services to each of the Banks. The Company believes that
this partnership between the Banks' management and Company personnel allows the
management of each of the Banks to focus on sales and customer service while
providing the Company with internal controls, and the ability to provide
consistent service quality and attain operating efficiencies.

BUSINESS STRATEGY
 
   
     The ability to profitably deploy the capital generated by the Company's
results of operations or otherwise maintain financial leverage is critical to
the Company's mission to create value for its shareholders. Much of the
Company's recent growth has resulted from acquisitions. The Company will
continue to consider opportunities for expansion through selective acquisitions
in markets where management believes its community banking approach creates a
competitive advantage. As part of this strategy, the Company has agreed to
acquire eight branch facilities from First of America Bank -- Michigan, National
Association, including approximately $121.5 million in deposits and $21.5
million in loans. See "Recent Developments."
    
 
     In the absence of suitable acquisition candidates, the Company will
continue to rely upon the Banks' ability to profitably fund loan growth with
nondeposit funding sources, including advances from the Federal Home Loan Bank,
as well as traditional deposit based funding sources. The cost of such
nondeposit funds is a principal consideration in the Banks' loan and deposit
pricing strategies.
 
     The Company intends to continue to focus on the management of its capital
resources. The Company's dividend policies and share repurchase plan have been
integral components of management's efforts to maintain profitable financial
leverage.
 
   
                              IBC CAPITAL FINANCE
    
 
   
     IBC Capital Finance ("IBC Capital") is a statutory business trust formed
under Delaware law pursuant to (i) the Trust Agreement executed by the Company,
as Depositor, State Street Bank and Trust Company, as Property Trustee,
Wilmington Trust Company, as Delaware Trustee, and the Administrative Trustees
named therein ("Trust Agreement"), and (ii) the filing of a certificate of trust
with the Delaware Secretary of State on November 7, 1996. IBC Capital's business
and affairs are conducted by its Property Trustee, Delaware Trustee, and three
individual Administrative Trustees who are employees or officers of or
affiliated with the Company. IBC Capital exists for the exclusive purposes of
(i) issuing and selling the Preferred Securities and Common Securities, (ii)
using the proceeds from the sale of Preferred Securities and Common Securities
to acquire Subordinated Debentures issued by the Company and (iii) engaging in
only those other activities necessary, advisable or incidental thereto (such as
registering the transfer of the Preferred Securities). Accordingly, the
Subordinated Debentures will be the sole assets of IBC Capital, and payments
under the Subordinated Debentures will be the sole revenue of IBC Capital. All
of the Common Securities will be owned by the Company. The Common Securities
will rank pari passu, and payments will be made thereon pro rata, with the
Preferred Securities, except that upon the occurrence and during the continuance
of an event of default under the Trust Agreement resulting from an Event of
Default under the Indenture, the rights of the Company as holder of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption or otherwise will be subordinated to the rights of the holders of the
Preferred Securities. See "Description of Preferred Securities -- Subordination
of Common Securities." The Company will acquire Common Securities in an
aggregate liquidation amount equal to 3% of the total capital of IBC Capital.
IBC Capital has a term of 55 years, but may terminate earlier as provided in the
Trust Agreement. The principal executive office of IBC Capital is 230 West Main
Street, Ionia, Michigan 48846, Attention: Secretary, and its telephone number is

                                 Security will be fixed at a rate per annum of
                                   % of the Liquidation Amount of $25 per
                                 Preferred Security, will be cumulative, will

Option to Extend Interest
Payment Period................   The Company has the right, at any time, to
                                 defer payments of interest on the Subordinated
                                 Debentures for a period not exceeding 20
                                 consecutive quarters; provided, that no
                                 Extension Period may extend beyond the Stated
                                 Maturity of the Subordinated Debentures. As a
                                 consequence of the Company's extension of the
                                 interest payment period, quarterly
                                 Distributions on the Preferred Securities would
                                 be deferred (though such Distributions would
                                 continue to accrue with interest thereon
                                 compounded quarterly, since interest would
                                 continue to accrue and compound on the
                                 Subordinated Debentures) during any such
                                 Extension Period. During an Extension Period,
                                 the Company will be prohibited, subject to
                                 certain exceptions described herein, from
                                 declaring or paying any cash distributions with
                                 respect to its capital stock or debt securities
                                 that rank pari passu with or junior to the
                                 Subordinated Debentures. Upon the termination
                                 of any Extension Period and the payment of all
                                 amounts then due, the Company may commence a
                                 new Extension Period, subject to the foregoing
                                 requirements. See "Description of Subordinated
                                 Debentures -- Option to Extend Interest Payment
                                 Period."
    
 
   
                                 Should an Extension Period occur, Preferred
                                 Security holders will continue to recognize
                                 interest income for United States federal
                                 income tax purposes. See "Certain Federal
                                 Income Tax Consequences -- Potential Extension
                                 of Interest Payment Period and Original Issue
                                 Discount."
    
 
   
Redemption....................   The Preferred Securities may be redeemed, in
                                 whole or in part, upon repayment of the
                                 Subordinated Debentures at maturity or their
                                 earlier redemption. Subject to Federal Reserve
                                 approval, if then required under applicable
                                 capital guidelines or policies of the Federal
                                 Reserve, the Subordinated Debentures are
                                 redeemable prior to maturity at the option of
                                 the Company (1) on or after           , 2001,
                                 in whole at any time or in part from time to
                                 time, or (2) at any time, in whole (but not in
                                 part), upon the occurrence and during the
                                 continuance of a Tax Event or an Investment
                                 Company Event, in each case at the redemption
                                 price equal to

Distribution of Subordinated
  Debentures..................   The Company has the right at any time to
                                 terminate the Preferred Securities and cause

                                  RISK FACTORS
 
   
     Prospective investors should carefully consider, together with the other
information contained and incorporated by reference in this Prospectus, the
following risk factors in evaluating the Company and its business and IBC
Capital before purchasing the Preferred Securities offered hereby. In
particular, prospective investors should note that this Prospectus contains
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995 and that actual results could differ materially
from those contemplated by such statements. The considerations listed below
represent certain important factors the Company believes could cause such
results to differ. These considerations are not intended to represent a complete
list of the general or specific risks that may affect the Company and IBC
Capital. It should be recognized that other risks may be significant, presently
or in the future, and the risks set forth below may affect the Company and IBC
Capital to a greater extent than indicated.
    
 
   
RISK FACTORS RELATING TO THE PREFERRED SECURITIES
    
 
   
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE SUBORDINATED
DEBENTURES
    
 
   
     The obligations of the Company under the Guarantee issued by the Company
for the benefit of the holders of Preferred Securities and under the
Subordinated Debentures are unsecured and rank subordinate and junior in right
of payment to all Senior Debt and Subordinated Debt of the Company and, in
certain circumstances relating to the dissolution, winding-up, liquidation or
reorganization of the Company, to all Additional Senior Obligations of the
Company. At September 30, 1996, the aggregate outstanding Senior Debt,
Subordinated Debt and Additional Senior Obligations of the Company was
approximately $750 million. Because the Company is a holding company, the right
of the Company to participate in any distribution of assets of any of the Banks
upon such Bank's liquidation or reorganization or otherwise (and thus the
ability of holders of the Preferred Securities to benefit indirectly from such
distribution), is subject to the prior claims of creditors of that Bank, except
to the extent that the Company may itself be recognized as a creditor of that
Bank. Accordingly, the Subordinated Debentures will be effectively subordinated
to all existing and future liabilities of the Banks, and holders of Subordinated
Debentures and Preferred Securities should look only to the assets of the
Company for payments on the Subordinated Debentures. Neither the Indenture, the
Guarantee nor the Trust Agreement places any limitation on the amount of secured
or unsecured debt, including Senior Debt, Subordinated Debt and Additional
Senior Obligations, that may be incurred by the Company. See "Description of
Guarantee -- Status of the Guarantee" and "Description of Subordinated
Debentures -- Subordination."
    
 
   
     The ability of IBC Capital to pay amounts due on the Preferred Securities
is solely dependent upon the Company making payments on the Subordinated
Debentures as and when required.
    
 
   
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES
    
 
   
     So long as no Event of Default under the Indenture has occurred or is
continuing, the Company has the right under the Indenture to defer the payment
of interest on the Subordinated Debentures at any time or from time to time for
a period not exceeding 20 consecutive quarters with respect to each Extension
Period, provided that no Extension Period may extend beyond the Stated Maturity
of the Subordinated Debentures. As a consequence of any such deferral, quarterly
Distributions on the Preferred Securities by IBC Capital will be deferred (and
the amount of Distributions to which holders of the Preferred Securities are
entitled will accumulate additional Distributions thereon at the rate of    %
per annum, compounded quarterly from the relevant payment date for such
Distributions) during any such Extension Period. During any such Extension
Period, the Company may not, and may not permit any subsidiary of the Company to
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of the Company's
capital stock, or (ii) make any payment of principal, interest or premium, if
any, on or repay, repurchase or redeem any debt securities of the Company that
rank pari passu with or junior in interest to the Subordinated Debentures or
make any guarantee payments with respect to any guarantee by the Company of the
debt securities of any subsidiary of the Company if such guarantee ranks pari
passu with or junior in interest to the Subordinated Debentures (other than (a)
dividends or distributions in Common
    
 
                                        9
<PAGE>   12
 
   
Stock, (b) any declaration of a dividend in connection with the implementation
of a shareholders' rights plan, or the issuance of stock under any such plan in
the future, or the redemption or repurchase of any such rights pursuant thereto,
(c) payments under the Guarantee and (d) purchases of Common Stock related to
the rights under any of the Company's benefit plans for its directors, officers
or employees). Prior to the termination of any such Extension Period, the
Company may further defer the payment of interest, provided that no Extension
Period may exceed 20 consecutive quarters or extend beyond the Stated Maturity
of the Subordinated Debentures. Upon the termination of any Extension Period and
the payment of all interest then accrued and unpaid (together with interest
thereon at the annual rate of    % compounded quarterly, to the extent permitted
by applicable law), the Company may elect to begin a new Extension Period
subject to the above requirements. There is no limitation on the number of times
that the Company may elect to begin an Extension Period. See "Description of
Preferred Securities -- General" and "Description of Subordinated Debentures --
Option to Extend Interest Payment Period."
    
 
   
     Should an Extension Period occur, a holder of Preferred Securities will be
required to accrue and recognize income (in the form of original issue discount)
in respect of its pro rata share of the interest accruing on the Subordinated
Debentures held by IBC Capital for United States federal income tax purposes. As
a result, a holder of Preferred Securities will include such income in gross
income for United States federal income tax purposes in advance of the receipt
of cash, and will not receive the cash related to such income from IBC Capital
if the holder disposes of the Preferred Securities prior to the record date for
the payment of the related Distributions. See "Certain Federal Income Tax
Consequences -- Potential Extension of Interest Payment Period and Original
Issue Discount."
    
 
   
     The Company has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the
Subordinated Debentures. However, should the Company elect to exercise such
right in the future, the market price of the Preferred Securities is likely to
be adversely affected. A holder that disposes of its Preferred Securities during
an Extension Period, therefore, might not receive the same return on its
investment as a holder that continues to hold its Preferred Securities. In
addition, as a result of the existence of the Company's right to defer interest
payments, the market price of the Preferred Securities may be more volatile than
the market prices of other securities on which original issue discount accrues
that are not subject to such optional deferrals.
    
 
   
TAX EVENT OR INVESTMENT COMPANY EVENT -- REDEMPTION
    
 
   
     Upon the occurrence and during the continuance of a Tax Event or Investment
Company Event (whether occurring before or after             , 2001) the Company
has the right to redeem the Subordinated Debentures in whole (but not in part)
within 90 days following the occurrence of such Tax Event or Investment Company
Event and therefore cause a mandatory redemption of the Preferred Securities.
The exercise of such right is subject to the Company having received prior
approval of the Federal Reserve to do so if then required under applicable
guidelines or policies of the Federal Reserve.
    
 
   
     A "Tax Event" means the receipt by IBC Capital of an opinion of counsel
experienced in such matters to the effect that, as a result of any amendment to,
or change (including any announced prospective change) in the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein, or as a result of any official
administrative pronouncement or judicial decision interpreting or applying such
laws or regulations, which amendment or change is effective or such
pronouncement or decision is announced on or after the date of issuance of the
Preferred Securities under the Trust Agreement, there is more than an
insubstantial risk that (i) IBC Capital is, or will be within 90 days of the
date of such opinion, subject to United States federal income tax with respect
to income received or accrued on the Subordinated Debentures, (ii) interest
payable by the Company on the Subordinated Debentures is not, or within 90 days
of such opinion, will not be, deductible by the Company, in whole or in part,
for United States federal income tax purposes, or (iii) IBC Capital is, or will
be within 90 days of the date of the opinion, subject to more than a de minimis
amount of other taxes, duties or other governmental charges.
    
 
   
     An "Investment Company Event" means the receipt by IBC Capital of an
opinion of counsel experienced in such matters to the effect that, as a result
of the occurrence of a change in law or regulation or a change in
    
 
                                       10

interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority, IBC Capital is or will be
considered an "investment company" that is required to be registered under the
Investment Company Act, which change becomes effective on or after the date of
original issuance of the Preferred Securities.
    
 
   
     See "Risk Factors -- Possible Tax Law Changes Affecting the Preferred
Securities" for a discussion of certain legislative proposals that, if adopted,
could give rise to a Tax Event, which may permit the Company to cause a
redemption of the Preferred Securities prior to             , 2001.
    
 
   
EXCHANGE OF PREFERRED SECURITIES FOR SUBORDINATED DEBENTURES
    
 
   
     The Company will have the right at any time to terminate IBC Capital and
cause the Subordinated Debentures to be distributed to the holders of the
Preferred Securities in liquidation of IBC Capital. The exercise of such right
is subject to the Company having received prior approval of the Federal Reserve
if then required under applicable capital guidelines or policies of the Federal
Reserve. See "Description of Preferred Securities -- Redemption or Exchange."
    
 
   
SHORTENING OF STATED MATURITY OF SUBORDINATED DEBENTURES
    
 
   
     The Company will have the right at any time to shorten the maturity of the
Subordinated Debentures to a date not earlier than             , 2001. The
exercise of such right is subject to the Company having received prior approval
of the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve.
    
 
   
EXTENSION OF STATED MATURITY OF SUBORDINATED DEBENTURES
    
 
   
     The Company will also have the right to extend the maturity of the
Subordinated Debentures whether or not IBC Capital is terminated and the
Subordinated Debentures are distributed to holders of the Preferred Securities
to a date no later than the 49th anniversary of the initial issuance of the
Preferred Securities, provided that the Company can extend the maturity only if
at the time such election is made and at the time of such extension (i) the
Company is not in bankruptcy, otherwise insolvent or in liquidation, (ii) the
Company is not in default in the payment of any interest or principal on the
Subordinated Debentures, and (iii) IBC Capital is not in arrears on payments of
Distributions on the Preferred Securities and no deferred Distributions are
accumulated.
    
 
   
RIGHTS UNDER THE GUARANTEE
    
 
   
     The Guarantee will be qualified as an indenture under the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act"). State Street Bank and Trust
Company ("State Street") will act as the indenture trustee under the Guarantee
(the "Guarantee Trustee") for the purposes of compliance with the Trust
Indenture Act and will hold the Guarantee for the benefit of the holders of the
Preferred Securities. State Street will also act as Debenture Trustee for the
Subordinated Debentures and as Property Trustee; Wilmington Trust Company will
act as Delaware Trustee under the Trust Agreement. The Guarantee guarantees to
the holders of the Preferred Securities the following payments, to the extent
not paid by IBC Capital: (i) any accumulated and unpaid Distributions required
to be paid on the Preferred Securities, to the extent that IBC Capital has funds
on hand available therefor at such time, (ii) the redemption price with respect
to any Preferred Securities called for redemption, to the extent that IBC
Capital has funds on hand available therefor at such time, and (iii) upon a
voluntary or involuntary dissolution, winding-up or liquidation of IBC Capital
(unless the Subordinated Debentures are distributed to holders of the Preferred
Securities), the lesser of (a) the aggregate of the Liquidation Amount and all
accumulated and unpaid Distributions to the date of payment to the extent that
IBC Capital has funds on hand available therefor at such time and (b) the amount
of assets of IBC Capital remaining available for distribution to holders of the
Preferred Securities. The holders of not less than a majority in aggregate
Liquidation Amount of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee
    
 
                                       11
<PAGE>   14
 
   
Trustee in respect of the Guarantee or to direct the exercise of any trust power
conferred upon the Guarantee Trustee under the Guarantee. Any holder of the
Preferred Securities may institute a legal proceeding directly against the
Company to enforce its rights under the Guarantee without first instituting a
legal proceeding against IBC Capital, the Guarantee Trustee or any other person
or entity. If the Company were to default on its obligation to pay amounts
payable under the Subordinated Debentures, IBC Capital would lack funds for the
payment of Distributions or amounts payable on redemption of the Preferred
Securities or otherwise, and, in such event, holders of Preferred Securities
would not be able to rely upon the Guarantee for such amounts. Instead, in the
event a Debenture Event of Default shall have occurred and be continuing and
such event is attributable to the failure of the Company to pay interest on or
principal of the Subordinated Debentures on the payment date on which such
payment is due and payable, then a holder of Preferred Securities may institute
a legal proceeding directly against the Company for enforcement of payment to
such holder of the principal of or interest on such Subordinated Debentures
having a principal amount equal to the aggregate Liquidation Amount of the
Preferred Securities of such holder (a "Direct Action"). In connection with such
Direct Action, the Company will have a right of set-off under the Indenture to
the extent of any payment made by the Company to such holder of Preferred
Securities in the Direct Action. Except as described herein, holders of
Preferred Securities will not be able to exercise directly any other remedy
available to the holders of the Subordinated Debentures or assert directly any
other rights in respect of the Subordinated Debentures. See "Description of
Subordinated Debentures -- Enforcement of Certain Rights by Holders of Preferred
Securities" and "-- Debenture Events of Default" and "Description of Guarantee."
The Trust Agreement provides that each holder of Preferred Securities by
acceptance thereof agrees to the provisions of the Guarantee and the Indenture.
    
 
   
LIMITED VOTING RIGHTS
    
 
   
     Holders of Preferred Securities will generally have limited voting rights
relating only to the modification of the Preferred Securities and the exercise
of IBC Capital's rights as holder of Subordinated Debentures and the Guarantee.
Holders of Preferred Securities will not be entitled to vote to appoint, remove
or replace the Property Trustee or the Delaware Trustee, and such voting rights
are vested exclusively in the holder of the Common Securities except upon the
occurrence of certain events described herein. The Property Trustee, the
Administrative Trustees and the Company may amend the Trust Agreement without
the consent of holders of Preferred Securities to ensure that IBC Capital will
be classified for United States federal income tax purposes as a grantor trust
even if such action adversely affects the interests of such holders. See
"Description of Preferred Securities -- Voting Rights; Amendment of Trust
Agreement" and "-- Removal of IBC Capital Trustees."
    
 
   
POSSIBLE TAX LAW CHANGES AFFECTING THE PREFERRED SECURITIES
    
 
   
     On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill") was
released which would, among other things, generally deny interest deductions for
interest on an instrument issued by a company that has a maximum weighted
average maturity of more than 40 years. The Bill would also generally deny
interest deductions for interest on an instrument, issued by a company, that has
a maximum term of more than 20 years and that is not shown as indebtedness on
the separate balance sheet of the issuer or, where the instrument is issued to a
related party (other than a corporation), where the holder or some other related
party issues a related instrument that is not shown as indebtedness on the
issuer's consolidated balance sheet. If either provision were to apply to the
Subordinated Debentures, the Company would be unable to deduct interest on the
Subordinated Debentures. However, on March 29, 1996, the Chairmen of the Senate
Finance and House Ways and Means Committees issued a joint statement to the
effect that it was their intention that the effective date of the President's
legislative proposals, if adopted, will be no earlier than the date of
appropriate Congressional action. Under current law, the Company will be able to
deduct interest on the Subordinated Debentures. There can be no assurance,
however, that current or future legislative proposals or final legislation will
not affect the ability of the Company to deduct interest on the Subordinated
Debentures. Such a change could give rise to a Tax Event, which may permit the
Company, upon approval of the Federal Reserve if then required under applicable
capital guidelines or policies of the Federal Reserve, to cause a redemption of
the Preferred Securities before, as well as after             , 2001. See
"Description of

Subordinated Debentures -- Redemption" and "Description of Preferred
Securities--Redemption or Exchange -- Tax Event Redemption." See also "Certain
Federal Income Tax Consequences -- Effect of Proposed Changes in Tax Laws."
    
 
   
RISK FACTORS RELATING TO THE COMPANY
    
 
NO ASSURANCE OF SUCCESSFUL INTEGRATION OF BRANCHES
 
   
     Based on September 30, 1996 financial information, the acquisition of the
eight branches from First of America Bank -- Michigan, National Association
("FOA Branches") by Independent Bank East Michigan ("IBEM"), a subsidiary of the
Company, would increase the assets of IBEM by approximately 107% to $239.4
million. See "Recent Developments." Although the Company has successfully
integrated other acquired banks and branch facilities into its operations in the
recent past without adversely affecting the profitability of such operations,
IBEM's ability to integrate the FOA Branches into its current operations without
adversely affecting the level of profitability of IBEM or the Company as a whole
cannot be assured.
    
 
IMPACT OF INTEREST RATE CHANGES
 
   
     The Company's results of operations are derived from the operations of the
Banks and are principally dependent on net interest income, calculated as the
difference between interest earned on loans and investments and the interest
expense paid on deposits and other borrowings. Like other banks and financial
institutions, the Company's interest income and interest expense are affected by
general economic conditions and by the policies of regulatory authorities,
including the monetary policies of the Federal Reserve. While management has
taken measures intended to manage the risks of operating in a changing interest
rate environment, there can be no assurance that such measures will be effective
in avoiding undue interest rate risk. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Asset/Liability Management."
    
 
CREDIT RISKS
 
     As a financial institution, the Company is exposed to the risk that
customers to whom the Banks have made loans will be unable to repay those loans
according to their terms and that collateral securing such loans (if any) may
not be sufficient in value to assure repayment. Credit losses could have a
material adverse effect on the Company's operating results.
 
REGULATORY RISK
 
   
     The banking industry is heavily regulated. These regulations are primarily
intended to protect depositors and the Federal Deposit Insurance Corporation
("FDIC"), not shareholders or other creditors. Regulations affecting the
financial institutions industry are undergoing continuous change, and the
ultimate effect of such changes cannot be predicted. Regulations and laws
affecting the Company and the Banks may be modified at any time, and new
legislation affecting financial institutions may be proposed and enacted. There
is no assurance that such modifications or new laws will not materially and
adversely affect the business, condition or operations of the Company and the
Banks. See "Supervision and Regulation."
    
 
COMPETITION
 
     The banking business is highly competitive. The Banks compete with other
commercial banks, savings and loan associations, credit unions, mortgage banking
companies, securities brokerage companies, insurance companies, and money market
mutual funds. Many of these competitors have substantially greater resources
than the Company and the Banks and offer certain services that the Company and
the Banks do not currently provide. Such competitors may also have greater
lending limits than the Banks. The number of competitors may increase as a
result of the easing of restrictions on interstate banking effected under the
Riegle-Neal Interstate Banking and Efficiency Act of 1994. In addition, non-bank
competitors are generally not subject to the extensive regulations applicable to
the Company and the Banks. See "Supervision and Regulation."
 
                                       13
<PAGE>   16
 
MARKET PRICES
 
     There can be no assurance as to the market prices for Preferred Securities
or Subordinated Debentures that may be distributed in exchange for Preferred
Securities if a liquidation of IBC Capital occurs. Accordingly, the Preferred
Securities that an investor may purchase, whether pursuant to the offer made
hereby or in the secondary market, or the Subordinated Debentures that a holder
of Preferred Securities may receive on liquidation of IBC Capital, may trade at
a discount to the price that the investor paid to purchase the Preferred
Securities offered hereby. In addition, there can be no assurance that the
Company will not exercise its option to change the maturity of the Subordinated
Debentures as permitted by the terms thereof and of the Indenture. Because
holders of Preferred Securities may receive Subordinated Debentures on
liquidation of IBC Capital, prospective purchasers of Preferred Securities are
also making an investment decision with regard to the Subordinated Debentures
and should carefully review all the information regarding the Subordinated
Debentures contained herein. See "Description of Subordinated Debentures."
 
TRADING CHARACTERISTICS OF PREFERRED SECURITIES
 
   
     The Preferred Securities may trade at prices that do not fully reflect the
value of accrued but unpaid interest with respect to the underlying Subordinated
Debentures. A holder of Preferred Securities that disposes of its Preferred
Securities between record dates for payments of Distributions (and consequently
does not receive a Distribution from IBC Capital for the period prior to such
disposition) will nevertheless be required to include accrued but unpaid
interest on the Subordinated Debentures through the date of disposition in
income as ordinary income and to add such amount to its adjusted tax basis in
the Preferred Securities disposed of. Such holder will recognize a capital loss
to the extent the selling price (which may not fully reflect the value of
accrued but unpaid interest) is less than its adjusted tax basis (which will
include accrued but unpaid interest). Subject to certain limited exceptions,
capital losses cannot be applied to offset ordinary income for United States
federal income tax purposes. See "Certain Federal Income Tax Consequences."
    
 
   
LACK OF MARKET FOR THE PREFERRED SECURITIES
    
 
   
     There is no current market for the Preferred Securities. Although the
Preferred Securities have been approved for quotation on the Nasdaq National
Market, there can be no assurance that an active public market will develop or
be maintained for the Preferred Securities. Stifel, Nicolaus & Company,
Incorporated has informed the Company that it presently intends to make a market
in the Preferred Securities, but no assurance can be given as to the liquidity
of the Preferred Securities in the market. See "Market for the Preferred
Securities" and "Underwriting."
    
 
   
EXPOSURE TO LOCAL ECONOMIC CONDITIONS
    
 
     The success of the Company and the Banks is dependent to a certain extent
upon the general economic conditions of the state of Michigan and the geographic
markets served by the Banks. No assurance can be given that favorable economic
conditions will continue to exist in such markets.
 
   
PREFERRED SECURITIES ARE NOT INSURED
    
 
   
     The Preferred Securities are not insured by the Bank Insurance Fund ("BIF")
or the Savings Association Insurance Fund ("SAIF") of the FDIC or by any other
governmental agency.

                              RECENT DEVELOPMENTS
 
     The discussion of recent developments contains forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995.
Actual results could differ materially from those projected in such
forward-looking statements as a result of, among other things, the factors set
forth in the section entitled "Risk Factors."
 
     Effective September 18, 1996, Independent Bank East Michigan ("IBEM"), a
subsidiary of the Company, agreed to acquire eight branch banking facilities
from First of America Bank -- Michigan, National Association ("FOA Branches").
The FOA Branches are located in the thumb region of eastern Michigan, in the
counties of Huron and Tuscola. Two of the FOA Branches are located in the City
of Bad Axe and one each in the townships or communities of Caseville, Elkton,
Kinde, Ubly, Sebewaing, and Gagetown. As of September 30, 1996, the FOA Branches
had approximately $121.5 million of deposits and $21.5 million of loans. The
acquisition, which is subject to regulatory approval, is expected to be
consummated in December 1996, and will be supported by proceeds from this
offering. See "Use of Proceeds." The real and personal property of the FOA
Branches are being acquired at net book value, and IBEM will pay a loan premium
of 1% on the loans to be acquired and a deposit premium of 6.875% on the
deposits to be assumed. The Company anticipates amortizing the core deposit
premium on a straight line basis over 12 years.
 
     The acquisition of the FOA Branches allows the Company to continue to
expand its branch banking network and further leverage the managerial resources
of the Company and IBEM. The FOA Branches are located in markets similar to
those historically served by the Banks and are contiguous to the communities
that are currently served by IBEM. The acquisition of the FOA Branches will
assist in establishing IBEM as a prominent provider of banking services in the
thumb region of eastern Michigan.
 
   
     The following pro forma financial information reflects the impact of the
issuance of the Preferred Securities by IBC Capital (and the related issuance of
the Subordinated Debentures by the Company) and the purchase of the FOA Branches
as if they were acquired by IBEM as of September 30, 1996. This pro forma
information is presented for informational purposes only as the purchase of the
FOA Branches is not considered the acquisition of a business.

                                USE OF PROCEEDS
 
   
     All of the proceeds from the sale of Preferred Securities will be invested
by IBC Capital in the Subordinated Debentures. The net proceeds to the Company
from the sale of Subordinated Debentures are estimated to be $       ($       if
the Underwriter's over-allotment option is exercised in full). The Company will
use the proceeds to increase the capital base of IBEM in contemplation of the
pending acquisition of the FOA Branches. See "Capitalization." In addition, the
proceeds from the offering will assist the Company in maintaining a Tier 1
capital leverage ratio of approximately 5.2% following the pending acquisition
of the FOA Branches and the recent acquisition of North Bank Corporation, and
may be used for other general corporate purposes. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Financial
Condition -- Capital Resources." Other than the pending acquisition of the FOA
Branches, the Company has no current or contemplated agreements or
understandings for any acquisitions. The Preferred Securities are expected to
qualify as Tier 1 capital.
    
 
   
                      MARKET FOR THE PREFERRED SECURITIES
    
 
   
     The Preferred Securities have been approved for quotation on the Nasdaq

has informed the Company that it presently intends to make a market in the
Preferred Securities. There can be no assurance, however, that an active and
liquid trading market will develop or, if developed, that such a market will
continue. The offering price and distribution rate have been determined by
negotiations among representatives of the Company and the Underwriter, and the
offering price of the Preferred Securities may not be indicative of the market
price following the offering. See "Underwriting."
    
 
   
                              ACCOUNTING TREATMENT
    
 
   
     For financial reporting purposes, IBC Capital will be treated as a

included in the consolidated financial statements of the Company. The Preferred
Securities will be presented as a separate line item in the consolidated balance
sheet of the Company under the caption "Company Obligated Mandatorily Redeemable
Preferred Securities of Subsidiary Trust Holding Solely Junior Subordinated
Debentures," and appropriate disclosures about the Preferred Securities, the
Guarantee and the Subordinated Debentures will be included in the notes to
consolidated financial statements. For financial reporting purposes, the Company
will record Distributions payable on the Preferred Securities as an expense in
the consolidated statements of operations.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
     The selected consolidated financial data set forth below, insofar as it
relates to the five years ended December 31, 1995, are derived from the audited
consolidated financial statements of the Company. The data for the nine-month
periods ended September 30, 1995 and 1996, have been derived from unaudited
interim financial statements; however, in the opinion of the Company, such
unaudited interim statements include all adjustments (consisting of normal
recurring accruals) necessary to fairly present the data for such periods. The
results of operations for the nine-month period ended September 30, 1996, are
not necessarily indicative of results to be achieved for the full year. Such
data are qualified by reference to the consolidated financial statements
included elsewhere in this Prospectus or incorporated by reference and should be
read in conjunction with such financial statements and related notes thereto and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     Management's discussion and analysis of financial condition and results of
operations contains forward-looking statements within the meaning of Section 27A
of the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. Actual results could differ materially from
those projected in such forward-looking statements as a result of, among other
things, the factors set forth in the section entitled "Risk Factors."
 
     The following presents management's discussion and analysis of the
Company's consolidated financial condition and results of operations as of the
dates and for the periods indicated. This discussion should be read in
conjunction with the Company's Consolidated Financial Statements and the
accompanying notes, and other financial data appearing elsewhere in this
Prospectus.
 
OVERVIEW
 
   
     Over the past five years, the Company has experienced a significant growth
in its assets while at the same time retaining a net interest margin that has
exceeded 5% of average earning assets. Since December 31, 1990, total assets
have increased by 119% to $793.2 million at September 30, 1996. During this same
time period, the Company's average return on equity exceeded 15%. Earnings per
share have grown by a compounded annual rate of 14.6% to $2.38 for the year
ended December 31, 1995, from $1.38 for the year ended December 31, 1991.
Earnings per share for the nine months ended September 30, 1996 totaled $2.02,
an increase of 16.1% from earnings of $1.74 per share for the first nine months
of 1995.
    
 
     Acquisitions of other banks and bank branches accounted for approximately
59% of the $430.7 million increase in total assets from December 31, 1990, to
September 30, 1996. Effective May 31, 1996, the Company acquired North Bank
Corporation ("NBC") in exchange for cash consideration totaling $15.8 million.
On the effective date of that transaction ("NBC Acquisition"), NBC's assets and
shareholders' equity totaled $152.0 million and $9.5 million, respectively, and
the Company recorded goodwill totaling $7.5 million.
 
   
     On March 7, 1994, the Company acquired KSB Financial, Inc. ("KSB") in
exchange for shares of the Company's Common Stock having an aggregate value of
$4.4 million. The transaction ("KSB Acquisition") was accounted for as a pooling
of interests and, at the effective date of the transaction, KSB's assets and
shareholders' equity totaled $37.2 million and $2.8 million, respectively.
During 1993, the Company acquired American Home Bank and Pioneer Bank ("1993
Acquisitions") in exchange for cash consideration totaling $7.1 million. On the
effective date of these transactions, aggregate assets and shareholders' equity
totaled $66.7 million and $6.6 million, respectively, and the Company recorded
goodwill totaling approximately $500,000.
    
 
     The Banks' ability to originate and fund rate-sensitive loans with other
borrowings has also provided an opportunity to profitably deploy the capital
generated by the retention of earnings ("Alternate Loan Funding Strategy").
Other borrowings and federal funds purchased totaled $191.0 million at September
30, 1996, compared to $14.1 million at December 31, 1993. The use of non-deposit
sources of funds is structured to complement the Banks' interest-rate risk
profile, and the cost of such borrowings is a principal consideration in the
Banks' loan and deposit pricing.
 
RESULTS OF OPERATIONS
 
     SUMMARY. Net income increased by 16.7% to $5.8 million during the nine
months ended September 30, 1996, from $5.0 million during the comparable period
of 1995. Earnings per share during those periods were equal to $2.02 and $1.74
in 1996 and 1995, respectively. During 1995, net income increased by 12.9% to a
record $6.8 million or $2.38 per share. A year earlier, net income increased by
7.6% to $6.0 million, equal to $2.09 per share, from $5.6 million or $1.95 per
share in 1993.
 
   
     The increases in net income principally reflect increases in average
earning assets that resulted from the acquisition of banks as well as the
successful implementation of the Alternate Loan Funding Strategy. Average
earning assets grew by 61.6% to $634.1 million during the first nine-month
period of 1996 from
    
 
                                       19
<PAGE>   22
 
$392.4 million for the year ended December 31, 1993. Over that same period, the
Company's annualized net interest income increased by 51.6% to $33.5 million in
1996 from $22.1 million in 1993. In addition to an increase in the absolute
level of average earning assets since 1993, the mix of average earning assets
has shifted toward higher yielding loans from other earning assets. During the
nine months ended September 30, 1996, loans comprised 76.6% of total average
earning assets, up from 66.1% for the year ended December 31, 1993.
 
     As a result of the Banks' ability to generate loans, principally single
family residential real estate mortgage loans, average earning assets increased
by 26.5% to $634.1 million during the nine-month period in 1996, from $501.3
million during the comparable period in 1995, and by 15.1% to $513.4 million
during 1995, from $446.0 million in 1994. During those respective periods, net
interest income increased by 21.3% and 11.3%. The recent NBC Acquisition also
contributed to the increase in average earning assets and net interest income
during 1996.

     The increase in the Company's return on average equity, relative to its
return on average assets, reflects management's efforts to profitably maintain
or enhance financial leverage within management's established risk parameters.
As a result of the NBC Acquisition and the Alternate Loan Funding Strategy, the
Company's leverage ratio (average assets divided by average equity) increased to
13.66 during the nine months ended September 30, 1996. During 1995, the leverage
ratio was equal to 12.44, compared to 12.16 and 11.47 in 1994 and 1993,
respectively.
 
     NET INTEREST INCOME. Tax equivalent net interest income increased by 21.1%
to $25.9 million during the nine months ended September 30, 1996, from $21.3
million during the comparable period a year earlier. The increase principally
reflects the $132.9 million increase in average earning assets generated by the
Alternate Loan Funding Strategy and the NBC Acquisition. Tax equivalent net
interest income as a percent of average earning assets declined to 5.45% during
the nine months ended September 30, 1996, from 5.69% during the comparable
period in 1995. Management attributes a portion of the 24 basis point decline to
the cost of non-deposit funds that were used to implement the Alternate Loan
Funding Strategy. The interest paid on unsecured borrowings that were used to
fund the NBC Acquisition offset a portion of the increase in tax equivalent net
interest income.

     Tax equivalent net interest income increased by 10.7% to $29.0 million
during 1995 and by 14.1% to $26.2 million in 1994. Such increases reflect
double-digit percentage increases in average earning assets during those
periods. Average earning assets increased by 15.1% to $513.4 million during
1995, and by 13.6% to $446.0 million during 1994. The Alternate Loan Funding
Strategy accounted for approximately 90% of the $67.4 million increase in
average earning assets during 1995, while the 1993 Acquisitions accounted for
approximately 70% of the $53.5 million increase in average earning assets for
the prior year.

     Tax equivalent net interest income was equal to 5.65% of average earning
assets during 1995 compared to 5.88% and 5.85% in 1994 and 1993, respectively.
Management attributes the 23 basis point decline during 1995 to the average cost
of other borrowings utilized to fund its Alternate Loan Funding Strategy. In
view of the respective contributions to net income and the Company's return on
average equity, management believes that its Alternate Loan Funding Strategy is
consistent with its goal to profitably deploy capital.

     Increases in loans as a percent of average earning assets has had a
favorable impact on tax equivalent net interest income as a percent of average
earning assets. For the first nine months of 1996 and 1995, loans were equal to
approximately 76.6% and 73.8% of average earning assets, respectively. Loans
were equal to approximately 74.5% of average earning assets in 1995 and 66.1% in
both 1994 and 1993. Management expects that the consummation of the pending
acquisition of the FOA Branches will initially reduce loans as a percent of
average earning assets and will have a corresponding negative impact on the
Company's tax equivalent net interest income as a percent of average earning
assets. Over time, management expects to reinvest the assets into loans
following consummation of the transaction.
 
     PROVISION FOR LOAN LOSSES. In addition to a subjective analysis of general
and local economic conditions, management's assessment of the allowance for loan
losses is based upon the amount and composition of loan balances, a systematic
review of specific credits and historical loss experience, as well as the
absolute level of nonperforming and impaired loans.
 
     The provision for loan losses totaled $942,000 during the nine months ended
September 30, 1996. The increase from $477,000 during the comparable period in
1995 resulted from the application of management's allocation methodology (as
described above) to the loans associated with the NBC Acquisition and the
increase in loans, excluding loans held for sale ("Portfolio Loans").
 
     The provision for loan losses totaled $636,000 in 1995, compared to
$473,000 in 1994 and $657,000 in 1993. Increases in the provision during 1995
principally reflect the increase in Portfolio Loans. The decrease in the
provision during 1994 reflects a subsequent decline in substandard assets that
had been acquired as a result of the 1993 Acquisitions and the KSB Acquisition
in 1994, and the corresponding increase in the unallocated portion of the
allowance for loan losses.
 
   
     NONINTEREST INCOME. Noninterest income increased by 49.9% during the nine
months ended September 30, 1996, from $2.7 million during the comparable period
in 1995. The increase reflects increases in net gains on the sale of real estate
mortgage loans, as well as increases in service charges on deposit accounts and
other income.
    
 
     Noninterest income totaled $3.8 million in 1995 compared to $3.1 million
and $3.9 million in 1994 and 1993, respectively. The increase in net gains on
real estate mortgage loans accounted for approximately 72% of the $665,000
increase in noninterest income during 1995. A year earlier, a decline in net
gains on the sale of such loans and net losses on the sale of securities
available for sale accounted for the $797,000 decrease in noninterest income.
 
     The following table sets forth the principal components of noninterest
income for each of the periods indicated.

     Service charges on deposit accounts, the largest component of noninterest
income, totaled $1.6 million and $1.4 million during the nine months ended
September 30, 1996 and 1995, respectively. The $202,000 increase in service
charges reflects the NBC Acquisition. During 1995, such service charges totaled
$1.9 million, essentially unchanged from 1994. The $303,000 increase to $1.9
million in 1994 from $1.6 million in 1993, principally reflects the impact of
the 1993 Acquisitions.

     Net gains on the sale of real estate mortgage loans totaled $1.3 million
and $405,000 during the nine months ended September 30, 1996 and 1995,
respectively. Such gains totaled $728,000 in 1995, compared to $249,000 in 1994
and $721,000 in 1993.
 
     Although the majority of the 209% increase in net gains on the sale of real
estate loans during 1996 reflects favorable economic conditions and an increase
in loans sold, management attributes 45% of the increase to the impact of
Statement of Financial Accounting Standards No. 122, "Accounting for Mortgage
Servicing Rights" ("SFAS #122"), and the increased sale of related servicing
rights. See "Statements of Financial Accounting Standards."
 
     In addition to an increase in loans sold, the 192% increase during 1995
reflects an increase in net gains as a percent of real estate mortgage loans
sold. The overall decline in net gains during 1994 reflects the combined effects
of a decrease in loans sold as well as a decrease in net gains as a percent of
loans sold.
 
     The following table sets forth certain information with respect to the
origination and sale of real estate mortgage loans, including the net gains
recognized on the sale of such loans.

     Consistent with management's desire to maintain profitable leverage, the
Banks continue to retain rate-sensitive real estate mortgage loans and sell the
majority of fixed-rate obligations. See "Financial Condition -- Asset/Liability
Management." Accordingly, the volume of loans sold is dependent upon the Banks'
ability to sustain or increase the origination of real estate mortgage loans as
well as consumer demand for fixed-rate loans. Net gains on the sale of such
loans are also dependent upon economic and competitive factors as well as the
Banks' ability to effectively manage exposure to changes in interest rates.
 
     To maintain customer relationships, the Banks have historically retained
servicing rights on real estate mortgage loans sold. During the nine months
ended 1996 and the year ended 1995, however, the Banks sold the related
servicing rights on $28.8 million and $19.7 million, respectively, of real
estate mortgage loans, principally loans underwritten pursuant to government
guarantees and loans that have been originated in markets that are not served by
the Banks' branch networks.
 
     The Company realized net losses of $130,000 and $110,000 on the sale of
securities available for sale during the nine months ended September 30, 1996
and 1995, respectively. The Company also realized net losses of $120,000 in 1995
and $174,000 in 1994 compared to net gains of $637,000 in 1993. Future gains and
losses will be dependent upon the Banks' asset/liability management needs as
well as the slope of the yield curve, the level of interest rates and other
pertinent factors. See "Financial Condition -- Asset/Liability Management."
 
     NONINTEREST EXPENSE. Noninterest expense totaled $19.8 million and $15.9
million during the nine months ended September 30, 1996 and 1995, respectively.
Noninterest expense totaled $21.7 million in 1995 compared to $19.5 million in
1994 and $17.5 million in 1993. Salaries and benefits are the largest component
of noninterest expense and account for the majority of the increase in total
noninterest expense. A reduction in FDIC insurance assessments, however, limited
the increase in total noninterest expense.

     The Company and the Banks maintain compensation policies and practices that
are intended to provide incentives for superior performance and align the
interests of officers and employees with those of the Company's shareholders.
Such "pay for performance" compensation plans include annual cash performance
awards, the Employee Stock Ownership Plan, the Employee Stock Option Plan and
the Incentive Share Grant Plan. Including commissions relating to the
origination of real estate mortgage loans, aggregate performance-based
compensation accounts for approximately 23% of the $2.5 million increase in
salaries and benefits during the nine months ended September 30, 1996, and
approximately 81% of the $1.6 million increase during 1995.
 
     The NBC Acquisition and the 1993 Acquisitions also had a substantive impact
on salaries and benefits as well as total noninterest expense. Management
estimates that the NBC Acquisition accounted for 33% and 45% of the increase in
salaries and benefits and total noninterest expense, respectively, during the
nine months ended September 30, 1996. During 1994, all of the increase in
salaries and benefits and 90% of the increase in total noninterest expense can
be attributed to the 1993 Acquisitions.
 
     Costs associated with new branch facilities, a write down of other real
estate as well as the introduction of the "EZ Money" check card and related ATM
conversions have also contributed to the increases in total noninterest expense
during the nine months ended September 30, 1996. Costs associated with the new
loan production offices or otherwise relating to the origination of real estate
mortgage loans contributed to the increase in occupancy, furniture and fixtures
and other noninterest expense during 1995. Environmental remediation costs
associated with two foreclosed properties also contributed approximately
$200,000 to the increase in noninterest expense. These remediation costs were
covered under the Michigan Underground Storage Tank Financial Assurance Fund
("MUSTFA"). MUSTFA announced that it was unable to fund all claims, however, and
the Company has provided for all remaining remediation costs as estimated by
environmental engineers.
 
FINANCIAL CONDITION
 
     SUMMARY. The Banks have committed significant resources to loan origination
efforts, including two new loan production offices during the second quarter of
1995. Portfolio Loans totaled $565.4 million at September 30, 1996, compared to
$418.0 million and $336.7 million at December 31, 1995 and 1994, respectively.
Excluding the impact of the NBC Acquisition, rate-sensitive real estate mortgage
loans accounted for approximately 67% and 72% of the increase in Portfolio Loans
during the first nine months of 1996 and for all of 1995, respectively.

<PAGE>   29
 
   
     In addition to the proceeds from security sales and maturities, the Banks
have relied on other borrowings to fund the increase in Portfolio Loans. The use
of such nondeposit funds, principally advances from the FHLB, complements the
Banks' core deposits and may further assist the Banks' efforts to manage their
exposure to changes in interest rates. See "-- Asset/Liability Management." Such
advances totaled $131.0 million at September 30, 1996, compared to $103.0
million and $40.0 million at December 31, 1995 and 1994, respectively.
    
 
     SECURITIES. The Banks maintain diversified securities portfolios that
include obligations of the U.S. Treasury and government-sponsored agencies as
well as securities issued by states and political subdivisions and
mortgage-backed securities. Securities available for sale are carried at fair
value and unrealized gains and losses, after consideration of applicable federal
income taxes, are recognized as a separate component of shareholders' equity.
 
     Management has the intent and the Banks have the ability to hold other
securities to maturity. These securities are carried at amortized cost without
adjustment for unrealized gains or losses. Although there are no current plans
to sell securities, management continues to evaluate the Banks' asset/liability
management needs and attempts to maintain a portfolio structure that will
improve earnings while maintaining sufficient liquidity and cash flow to fund
loans.
 
     The following tables set forth the book value of securities at the
specified dates and certain information with respect to the securities
portfolios, including gross unrealized gains and losses.

     LOAN PORTFOLIOS. Management believes that the stable and diversified
economies of the Banks' principal markets provide attractive lending
opportunities. In addition to the communities served by the Banks' branch
networks and loan production offices, the principal lending markets include
nearby communities and metropolitan areas. Subject to established underwriting
criteria, the Banks may also participate in commercial lending transactions with
certain non-affiliated banks and purchase real estate mortgage loans from
third-party originators.
 
     Management believes that its decentralized structure provides the Banks
with important advantages in serving the needs of its principal lending markets.
Although the management and Board of Directors of each of the Banks retain
authority and responsibility for all credit decisions, each of the Banks has
adopted uniform underwriting standards. The Company's loan committee and the
centralization of credit services promote compliance with these underwriting
standards and provide internal controls that are consistent with the needs of a
decentralized management structure. The Company's centralized credit services,
which include credit analysis and commercial loan review, also provide economies
of scale. The centralization of retail loan services further provides for
consistent service quality and facilitates compliance with applicable consumer
protection laws and regulations.

at the dates indicated.

     The increases in nonperforming loans and assets during 1996 were the result
of the NBC Acquisition. In the absence of that transaction, nonperforming loans
would have declined to $2.5 million, equal to 0.52% of Portfolio Loans at
September 30, 1996, and nonperforming assets would have declined to $3.3 million
or 0.68% of Portfolio Loans.
 
     The consistent decline in nonperforming loans and assets during 1995 and
1994 largely reflects a decrease in substandard assets originally acquired in
connection with the KSB Acquisition in 1994, as well as the 1993 Acquisitions.
Nonperforming assets associated with these acquisitions totaled $1.4 million,
$2.3 million, and $2.0 million at December 31, 1995, 1994, and 1993,
respectively.
 
     Impaired loans totaled approximately $2.2 million at September 30, 1996. In
addition to certain nonperforming loans, such impaired loans include commercial
and agricultural loans totaling $800,000 that have been separately identified as
impaired. Certain impaired loans with a balance of approximately $1.0 million at
September 30, 1996, had specific allocations of the allowance for loan losses
totaling approximately $125,000. The Company's average investment in impaired
loans was approximately $2.5 million during the nine-month period ended
September 30, 1996, and interest income recognized on impaired loans during that
period totaled approximately $110,000.

     The allowance for loan losses is maintained at a level that management
considers appropriate, based upon its assessment of relevant circumstances, by
charges to the associated provision for loan losses. See "-- Provision for Loan
Losses." In performing its assessment, management allocates a portion of the
allowance to specific loans and loan portfolios. Although the allowance for loan
losses has declined as a percent of Portfolio Loans, the unallocated portion of
the allowance increased to 57.3% of the total allowance at September 30, 1996,
from 41.5% at December 31, 1993.
    
 
     The following table sets forth management's allocation of the allowance for

     Loans charged against the allowance for loan losses, net of recoveries
("Net Losses"), were $395,000 during the nine months ended September 30, 1996,
compared to $282,000 during the comparable period of 1995. The NBC Acquisition
accounted for $90,000 of the $113,000 increase in Net Losses during 1996. Net
Losses in 1995 were $447,000 compared to $472,000 and $383,000 in 1994 and 1993,
respectively. Management estimates that Net Losses relating to loans that were
acquired as a result of the 1993 Acquisitions and the KSB Acquisition in 1994
were $50,000 in 1995, $130,000 in 1994, and $60,000 in 1993.
 
     DEPOSITS AND BORROWINGS. Deposits totaled $541.8 million at September 30,
1996, compared to $411.6 million at December 31, 1995. The NBC Acquisition
accounted for the majority of the $130.2 million increase in deposits.
Notwithstanding the purchase of a branch facility with deposits totaling $14.4
million during 1995, total deposits at December 31, 1995 increased only slightly
from $409.5 million one year earlier.

     The Banks' competitive position within many of the markets served by the
branch networks may limit the ability to materially increase deposits without
adversely impacting the weighted-average cost of core deposits. Accordingly, the
Banks have relied on other borrowed funds, principally advances from the FHLB,
to fund loans as part of its Alternate Loan Funding Strategy, while utilizing
pricing strategies that are intended to reduce the weighted-average cost of core
deposits. The use of non-deposit funds is structured to complement the Banks'
existing interest rate risk profile and may further reduce the Banks' exposure
to depositors' options to withdraw funds prior to maturity.
 
     The Company utilizes federal funds purchased and other borrowings,
including FHLB advances, to fund a portion of its earning assets. During the
nine months ended September 30, 1996, such other borrowings funded approximately
21.8% of average earning assets compared to 17.4% and 6.9% during the years
ended December 31, 1995 and 1994, respectively.
 
   
     FHLB advances are secured by the Banks' unencumbered qualifying real estate
mortgage loans as well as certain securities equal to 170% of outstanding
advances. To increase its aggregate borrowing capacity, management may elect to
secure FHLB advances by pledging specific collateral representing 105% to 125%
of outstanding advances. Management believes brokered certificates of deposit to
be a viable alternative to further diversify the Banks' funding sources.

     CAPITAL RESOURCES. The ability to profitably deploy the capital generated
by the Company's results of operations or otherwise maintain financial leverage
is critical to management's mission to create value for the Company's
shareholders. During periods when management believes there has been an absence
of suitable acquisition candidates, the Company's Alternate Loan Funding
Strategy has made important contributions to the Company's net income and return
on average equity. In view of the franchise value associated with core deposits
and other customer relationships, management believes that its approach to
acquisitions has also provided value to the Company's shareholders.
 
     The following table sets forth the Company's capital ratios at the dates
indicated.

     The Company's dividend policies and its share repurchase plan have been
integral components of management's efforts to maintain profitable financial
leverage. Cash dividends declared were equal to 36.5% of earnings for the first
nine months of 1996, 36.8% and 34.6% for the years ended December 31, 1995 and
1994, respectively. Although there are no current plans to repurchase shares of
its capital stock, the Company purchased 35,900 and 40,000 shares of its Common
Stock during 1995 and 1994, respectively.
 
     Shareholders' equity totaled $50.7 million at September 30, 1996, compared
to $47.0 million and $40.3 million at December 31, 1995 and 1994, respectively.
The increase in shareholders' equity reflects the retention of earnings as well
as the value of shares of Common Stock that have been issued pursuant to the
Incentive Share Grant Plan and the Company's various stock option plans.
 
     As a result of the NBC Acquisition, shareholders' equity declined to 6.40%
of total assets at September 30, 1996, compared to 7.97% and 7.81% at December
31, 1995, and 1994, respectively. In the absence of that transaction, however,
shareholders' equity would have been largely unchanged from December 31, 1995.
 
     ASSET/LIABILITY MANAGEMENT. The asset/liability management efforts of the
Company and the Banks are intended to identify and evaluate opportunities to
structure the balance sheet in a manner that is consistent with management's
mission to maintain profitable financial leverage within established risk
parameters. Accordingly, management's evaluations of alternate strategies
carefully consider the likely impact on the Banks' risk profile as well as the
anticipated contributions to earnings.
 
     Management employs simulation analyses to evaluate the potential changes in
the Banks' net interest income and market value of portfolio equity that result
from changes in interest rates. Such analyses further anticipate the potential
changes in the slope of the U.S. Treasury yield curve as well as changes in
prepayment rates on certain assets and premature withdrawals of certificates of
deposit that will likely accompany changes in interest rates.
 
     Consistent with management's intent to maintain profitable financial
leverage, the marginal cost of non-deposit funds is a principal consideration in
the Banks' decision to sell or retain real estate mortgage loans. Marginal
funding costs are also an integral component in pricing Portfolio Loans.
Management's ongoing evaluations have determined that the retention of 15- and
30-year fixed-rate real estate mortgage loans is not consistent with its goal to
profitably deploy capital or the Banks' asset/liability management needs.
Accordingly, the majority of such loans are sold to mitigate exposure to changes
in interest rates. Adjustable-rate and balloon real estate mortgage loans may,
however, be profitably funded with FHLB advances and the retention of such loans
is a principal focus of the Alternate Loan Funding Strategy. See "Results of
Operations--Noninterest Income."

STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS
 
     The Company adopted SFAS #122 effective January 1, 1996. SFAS #122 requires
the Banks to recognize as separate assets the rights to service mortgage loans
for others that have been acquired through either a purchase or origination of a
loan. The fair value of capitalized originated mortgage servicing rights has
been determined based on market value quotes for similar servicing. These
mortgage servicing rights are amortized in proportion to and over the period of
estimated net loan servicing income. SFAS #122 also requires the Banks to assess
these mortgage servicing rights for impairment based on the fair value of those
rights. For purposes of measuring impairment, the risk characteristics used by
the Banks include the underlying loans' interest rates, term of loan and loan
types.
 
     The Banks capitalized approximately $258,000 of originated servicing rights
during the nine months ended September 30, 1996, of which approximately $34,000
has been amortized.
 
     The Company also adopted Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation," ("SFAS #123"), effective January
1, 1996. SFAS #123 encourages companies to adopt a fair value method of
accounting for stock compensation plans. Those companies not adopting a fair
value method are required to make pro-forma disclosures of net income and
earnings per share, on an annual basis, as if they had adopted the fair value
accounting method. Management has elected the pro-forma disclosure method and
will do so on an annual basis.

GENERAL
 
   
     The Company is a bank holding company with four wholly owned subsidiary
banks engaged in the business of retail and commercial banking in portions of
Michigan's lower peninsula. IBC Capital, a wholly owned subsidiary of the
Company, exists for the purpose of issuing the Preferred Securities and has no
independent operations. Headquartered in Ionia, Michigan, the Company was formed
in 1973 as the parent company of Independent Bank. Each of the Banks is a state
chartered Michigan banking corporation, the business of each of which is
described in more detail below.
    
 
     Collectively, the Banks serve over 45 communities through their four main
offices and a total of 45 branches and five loan production offices. Management
attributes the Company's success to its consistent application of community
banking practices in predominantly rural and suburban markets. The Company's
decentralized management structure, which empowers and encourages local decision
making, represents the core of the Company's community banking philosophy. This
autonomy allows local bank management to better anticipate and respond to
customer demands and thereby enhances and improves customer service and
convenience, the principal means by which the Banks compete in the delivery of
financial services.
 
     The Company's principal sources of revenue, on a consolidated basis, are
interest and fees on loans, other interest income and non-interest income. The
sources of income for the three most recent years, and each of the nine-month
periods ended September 30, 1995 and 1996 are as follows:

RECENT GROWTH
 
     Much of the Company's recent growth has resulted from acquisitions. Since
1993, the Company has acquired four Michigan banks, two branch facilities and
established five real estate mortgage loan production offices. As a result, the
Company's assets have grown to approximately $793.2 million at September 30,
1996, from $403.1 million at December 31, 1992.
 
     In October 1993, the Company acquired American Home Bank ("American") and
Pioneer Bank ("Pioneer"), with assets of approximately $32 million and $35
million, respectively. The purchase price of $2.5 million for American
approximated its then book value, while the purchase price of $4.5 million for
Pioneer represented a premium of approximately 15% to Pioneer's book value. In
March 1994, the Company increased its assets by approximately $37.2 million by
acquiring KSB and its wholly owned subsidiary The Kingston State Bank
("Kingston"). In connection with this acquisition, the Company issued shares of
its Common Stock with a market value of approximately $4.4 million, representing
a premium of roughly 15% to KSB's book value. American, Pioneer and Kingston
have been consolidated to form IBEM. Effective May 31, 1996, the Company
acquired NBC, with assets of approximately $152.0 million, for cash in the
amount of $15.8 million. This represented a premium of approximately 66% to
NBC's book value. North Bank, NBC's wholly-owned subsidiary bank, was
consolidated with Independent Bank on August 12, 1996.

THE COMPANY'S APPROACH TO COMMUNITY BANKING
 
     The Company's operating philosophy preserves those elements of traditional
community banking which management believes create a competitive advantage in
the markets in which it operates. Among these are a high level of personal
service and customer recognition, prompt response to customer needs,
convenience, continuity of personnel and management, and commitment to and
participation in the community. Management attributes the Company's success in
preserving its community banking practices in the face of its recent growth to
three primary characteristics; (1) decentralized bank management, (2)
corporate-wide administrative and technical support, and (3) experienced Company
and Bank management.
 
     DECENTRALIZED MANAGEMENT. The Company believes that vesting management and
the boards of the Banks with the authority to make local decisions allows the
Banks to better anticipate customer needs, respond to customer demands, and
identify profitable opportunities within their respective markets. To provide
the flexibility to effectively pursue these opportunities, the Company's
decentralized management structure vests pricing and credit decisions in the
management of the respective Banks. While management of each of the Banks is
granted the authority to make decisions for its local operations, it is also
held accountable for its performance.
 
     CORPORATE ADMINISTRATIVE AND SUPPORT SERVICES. To complement the
decentralized management structure of the Company and establish consistent
service and quality and attain operating efficiencies, the Company's corporate
service departments provide a variety of services to each of the Banks. These
services include data processing, accounting and audit services, purchasing and
risk management, commercial loan credit analysis, servicing and review, consumer
loan servicing, real estate mortgage loan underwriting, servicing and secondary
market operations, asset/liability management and marketing services. The
Company believes that this partnership between the Banks' management and Company
personnel allows the management of each of the Banks to focus on sales and
marketing and at the same time provides the Company with the internal controls
that are consistent with the needs of a decentralized organization. Further,
this combination of decentralized management and centralized services provides
economies of scale that permit the Company to attract and retain talented
managers that possess specific expertise in areas that the Banks could not
achieve on an individual basis.
 
     MANAGEMENT EXPERIENCE AND COMPENSATION. The Company's growth and
profitability is also attributable to management's experience in providing
community banking services. The Banks' four presidents, along with the Company's
two executive officers, have been employed by the Company, on average, for over
10 years. Set forth below is a list of the Company's executive officers and Bank
presidents, their respective ages and financial industry experience.

</TABLE>
 
     The Company's growth has allowed it to recruit and retain experienced
individuals, and the recent acquisitions have added experienced community
bankers to its franchise. The Company's compensation policies and practices are
central to the maintenance of its decentralized management structure, and are
intended to promote and support local Bank autonomy while at the same time
enhancing overall Company performance. As an example, individual bonuses are
currently based on the performance of the Bank the employee works for, as well
as the overall performance of the Company. The Company believes that this
 
                                       35
<PAGE>   38
 
   
combination promotes individual bank performance and at the same time helps to
ensure that results are to the ultimate benefit of the Company's shareholders.
In addition to cash incentive plans, the Company maintains a variety of
equity-based plans to provide incentives for superior performance and to align
the interests of its executive officers and managers with those of the Company's
shareholders. Such "pay for performance" compensation plans include annual cash
performance awards, the Employee Stock Ownership Plan, the Employee Stock Option
Plan and the Incentive Share Grant Plan. As a result of these policies and
practices, every full-time employee, subject to certain employment conditions,
has an equity interest in the Company. Collectively, the Company's directors and
executive officers and Bank presidents own approximately 12.7% of the Company's
Common Stock, and as such have a vested interest in the Company's future success
and growth.
    
 
BUSINESS STRATEGY
 
     The Company intends to supplement its internal growth with selective
acquisitions, while at the same time managing its capital resources. One of the
principal challenges confronting the Company, in light of its recent growth, is
the preservation of its decentralized management structure, which represents the
core of its community banking foundation.
 
   
     INTERNAL GROWTH. Management believes that the stable and diversified
economies of the suburban and rural communities served by the Banks' offices, as
well as nearby communities and metropolitan areas, provide attractive markets
for the Company's traditional commercial banking services. Although the
financial services industry continues to be highly competitive, in view of the
limited competition within many of the Banks' principal markets, the Company's
community banking philosophy emphasizes a high level of service and convenience
as the principal means of competition.
    
 
     The markets served by the Banks provide attractive opportunities for
maintaining favorable net interest margins; however, the predominantly rural and
suburban nature of these markets presents certain challenges to the Company's
ability to grow. In the face of this challenge, the Banks have utilized various
strategies, based upon the particular attributes of their respective markets, to
provide asset growth and profitably deploy capital. In the absence of meaningful
deposit growth within those markets, the Banks have increasingly relied on
advances from the FHLB to fund the increase in assets. The Company intends to
encourage the Banks to continue to operate autonomously to provide the
flexibility that may be necessary to take advantage of opportunities in their
respective markets.
 
     The Company's corporate service departments develop various expertise to
assist the Banks and Bank management. In addition, the Banks share certain
expertise and experiences with one another. This sharing of expertise and
general coordination among the Company and the Banks is accomplished through a
network of holding company committees. The Company intends to continue to
promote the development of expertise and coordination among the Banks in order
to foster the Banks' growth in their respective markets.
 
   
     ACQUISITION STRATEGY. The Company will continue to consider opportunities
for expansion through selective acquisitions in markets where management
believes its community banking approach creates a competitive advantage. In
order to capitalize upon its existing banking network, the Company will continue
to focus primarily on acquisitions in contiguous markets; however, the Company
may consider expansion into noncontiguous markets in instances where management
believes that opportunities exist to enhance shareholder value and allow for
effective application of its community banking practices. Management believes
that, given its relative size, the Company can sustain meaningful growth through
acquisitions in markets that are attractive to the Company but may not be of
sufficient size to interest its larger competitors.
    
 
   
     CAPITAL MANAGEMENT. The Company intends to continue to focus on managing
its capital to provide an attractive return on its shareholders' investment. The
Company's dividend policies and share repurchase plan have been integral
components of management's efforts to maintain profitable financial leverage
within management's established risk parameters. Cash dividends declared were
equal to 36.5% of earnings for the first nine months of 1996, and were 36.8% and
34.6% of earnings in 1995 and 1994, respectively. Since January 1, 1994, the
Company repurchased approximately 75,900 shares of its Common Stock. The Company
may rely upon these capital management practices, in the absence of profitable
growth opportunities, as part of its goal of achieving an attractive return on
its shareholders' investment.

     The Banks' activities cover traditional phases of retail and commercial
banking, including checking and savings accounts, commercial and agricultural
lending, direct and indirect consumer financing, mortgage lending and deposit
box services. The Banks do not offer trust services. Most of the Banks' offices
provide full service lobby and drive-in services in the communities which they
serve. Automated teller machines are also provided at most locations.
 
     Principally located in rural and suburban communities, the Banks face
limited competition within certain of their primary markets. In general,
however, the financial services industry is highly competitive. Banks and bank
holding companies compete not only with each other, but with savings and loan
associations, money market mutual funds, credit unions, securities dealers,
providers of insurance and annuity fund products and investment bankers. The
market share information appearing below is derived from the June 30, 1995
deposit balances made available by the federal banking regulatory agencies.
 
     As of September 30, 1996, the Company and the Banks had 407 full-time
employees and 169 part-time employees.
 
INDEPENDENT BANK
 
   
     Independent Bank ("IB"), founded in 1864, operates in two geographically
distinct regions. Its south region consists of most of Ionia County and adjacent
townships in Montcalm County. Ionia County, with a population of nearly 60,000,
is located between the Grand Rapids and Lansing metropolitan areas. Within this
region, IB is the only depository institution in several communities. IB's
market share, in communities where its branches are located, exceeds 30% of
total deposits.
    
 
     IB's north region is comprised of the former branches of North Bank,
acquired as a result of the NBC Acquisition. IB defines its markets in this
region of northeastern Michigan as the counties of Iosco, Alpena and Presque
Isle, along with portions of Ogemaw, Alcona and Montmorency counties. IB's
northeastern branches are located in Hale, Tawas City, Rogers City, Rose City,
Whittemore, Glennie, Hillman and Hubbard Lake, as well as the larger communities
of Alpena and Oscoda. Within seven of the ten communities served by its branches
in this region, IB's market share of deposits exceeds 50%, and it is the only
bank with an office located within four of these communities.
 
     While the regions are geographically distinct, the rural communities served
by IB's branches are demographically similar and rely on an economic base that
includes manufacturers, service and retail businesses, agriculture, mining,
forest products and government. Notwithstanding these similarities, Ionia
County's population and IB's business benefit from the region's proximity to
Grand Rapids and Lansing as well as the six facilities of the Michigan
Department of Corrections that are located in Ionia and Carson City. IB's
northeastern region benefits from a substantial retirement population as well as
vacationers.

INDEPENDENT BANK WEST MICHIGAN
 
     The main office of Independent Bank West Michigan ("IBWM") is located in
Rockford, a northern suburb of Grand Rapids. IBWM's branches serve the
communities of Howard City, Sand Lake, Cedar Springs, White Cloud, Newaygo,
Sparta and Croton Hardy located in northern Kent County, western Montcalm County
and southern Newaygo County. IBWM is the only financial institution with an
office in two of these communities; within three other markets IBWM's market
share exceeds 55% of total deposits. Additionally, IBWM has established loan
production offices with 21 commissioned real estate mortgage loan originators
that serve Muskegon, Mecosta and Ottawa counties.
 
     IBWM's principal markets contain two distinct demographic groups. As a
suburb of Grand Rapids, Rockford is a fast growing, affluent residential
community while most of the remaining markets are rural. Reflecting the profile
of its markets, IBWM has emphasized consumer banking and, given the rapid growth
of western Michigan, real estate mortgage lending. As a result of IBWM's success
in real estate mortgage lending, the Company has experience in secondary
marketing and servicing that promotes the success of the other Banks.
 
INDEPENDENT BANK SOUTH MICHIGAN
 
   
     Independent Bank South Michigan ("IBSM") has its headquarters in Leslie,
located between Lansing and Jackson. IBSM's branches are located in Ingham and
Eaton counties and the northern portion of Jackson County. Within the
communities of Rives Junction, Pleasant Lake, Potterville, Vermontville and
Leslie, IBSM is the only depository institution. Within seven of the nine
communities served by IBSM's branches, its market share exceeds 60% of total
deposits. Principal employers within this market include General Motors
Corporation, the State of Michigan and Michigan State University.
    
 
     Although historically characterized as an agricultural bank, IBSM has
increased its focus on consumer and real estate mortgage lending and, to a
lesser degree, the non-agricultural commercial lending opportunities within its
markets. Its Okemos-based loan production office serves the greater Lansing area
and further leverages the Company's expertise in real estate mortgage lending.
 
INDEPENDENT BANK EAST MICHIGAN
 
   
     The main office of IBEM is located in Caro, centrally located in Tuscola
County in the heart of eastern Michigan's thumb region. In addition to the
communities of Unionville, Kingston, Snover and Reese within Tuscola County,
IBEM's branches serve Clifford, North Branch, Clio and Marlette located in
northern Lapeer, Sanilac and Genesse counties. Within four of these communities,
IBEM is the only depository institution. Notwithstanding the agricultural-based
economy of the thumb region, IBEM's markets benefit from their proximity to the
Detroit metropolitan areas.
    
 
   
     The pending acquisition of the FOA Branches, located in the communities of
Bad Axe, Sebewaing, Caseville, Elkton, Kinde, Ubly and Gagetown will add
approximately $122 million of deposits. As a result, IBEM will become the
largest depository institution in Huron County with a market share of
approximately 25% of total deposits.
    
 
LEGAL PROCEEDINGS
 
     The Company and the Banks are parties to various claims, complaints and
other legal actions that have arisen in the ordinary course of business from
time to time. Management believes that the outcome of all pending legal
proceedings, in the aggregate, will not have a material adverse effect on the
Company's or the Banks' business, results of operations or financial condition.

                           SUPERVISION AND REGULATION
 
     The following is a summary of certain statutes and regulations affecting
the Company and the Banks. This summary is qualified in its entirety by
reference to the particular statutes and regulations. A change in applicable
laws or regulations may have a material effect on the Company, the Banks and the
businesses of the Company and the Banks. See "Risk Factors."
 
GENERAL
 
   
     Financial institutions and their holding companies are extensively
regulated under federal and state law. Consequently, the growth and earnings
performance of the Company and the Banks can be affected not only by management
decisions and general and local economic conditions, but also by the statutes
administered by, and the regulations and policies of, various governmental
regulatory authorities. Those authorities include, but are not limited to the
Federal Reserve, the FDIC, the Commissioner of the Michigan Financial
Institutions Bureau ("Commissioner"), the Internal Revenue Service, and state
taxing authorities. The effect of such statutes, regulations and policies and
any changes thereto can be significant and cannot be predicted.
    
 
     Federal and state laws and regulations generally applicable to financial
institutions and their holding companies regulate, among other things, the scope
of business, investments, reserves against deposits, capital levels relative to
operations, lending activities and practices, the nature and amount of
collateral for loans, the establishment of branches, mergers, consolidations and
dividends. The system of supervision and regulation applicable to the Company
and the Banks establishes a comprehensive framework for their respective
operations and is intended primarily for the protection of the FDIC's deposit
insurance funds, the depositors of the Banks, and the public, rather than
shareholders of the Company.
 
     Federal law and regulations, including provisions added by the Federal
Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA") and regulations
promulgated thereunder, establish supervisory standards applicable to the
lending activities of the Banks, including internal controls, credit
underwriting, loan documentation, and loan-to-value ratios for loans secured by
real property.
 
THE COMPANY
 
   
     GENERAL. The Company is a bank holding company and, as such, is registered
with, and subject to regulation by, the Federal Reserve under the Bank Holding
Company Act, as amended (the "BHCA"). Under the BHCA, the Company is subject to
periodic examination by the Federal Reserve, and is required to file periodic
reports of its operations and such additional information as the Federal Reserve
may require.
    
 
   
     In accordance with Federal Reserve policy, the Company is expected to act
as a source of financial strength to the Banks and to commit resources to
support the Banks in circumstances where the Company might not do so absent such
policy. In addition, in certain circumstances a Michigan state bank having
impaired capital may be required by the Commissioner either to restore the
bank's capital by a special assessment upon its shareholders, or to initiate the
liquidation of the bank.
    
 
   
     Any capital loans by a bank holding company to a subsidiary bank are
subordinate in right of payment to deposits and to certain other indebtedness of
such subsidiary bank. In the event of a bank holding company's bankruptcy, any
commitment by the bank holding company to a federal bank regulatory agency to
maintain the capital of a subsidiary bank will be assumed by the bankruptcy
trustee and entitled to a priority of payment.
    
 
   
     INVESTMENTS AND ACTIVITIES. Under the BHCA, bank holding companies are
prohibited, with certain limited exceptions, from engaging in activities other
than those of banking or of managing or controlling banks and from acquiring or
retaining direct or indirect ownership or control of voting shares or assets of
any company which is not a bank or bank holding company, other than subsidiary
companies furnishing services to or performing services for its subsidiaries,
and other subsidiaries engaged in activities which, by the Federal Reserve's
determination, are closely related to banking or managing or controlling banks.
Since September 29, 1995, the BHCA has permitted the Federal Reserve under
specified circumstances to approve the acquisition
    
 
                                       39
<PAGE>   42
 
by a bank holding company located in one state, of a bank or bank holding
company located in another state, without regard to any prohibition contained in
state law. See "Recent Regulatory Developments."
 
   
     In general, any direct or indirect acquisition by the Company of any voting
shares of any bank which would result in the Company's direct or indirect
ownership or control of more than 5% of any class of voting shares of such bank,
and any merger or consolidation of the Company with another bank holding
company, will require the prior written approval of the Federal Reserve under
the BHCA. In acting on such applications, the Federal Reserve must consider
various statutory factors, including among others, the effect of the proposed
transaction on competition in relevant geographic and product markets, and each
party's financial condition, managerial resources, and record of performance
under the Community Reinvestment Act.
    
 
   
     In addition and subject to certain exceptions, the Change in the Bank
Control Act ("Control Act") and regulations promulgated thereunder by the
Federal Reserve, require any person acting directly or indirectly, or through or
in concert with one or more persons, to give the Federal Reserve 60 days'
written notice before acquiring control of a bank holding company. Transactions
which are presumed to constitute the acquisition of control include the
acquisition of any voting securities of a bank holding company having securities
registered under Section 12 of the Securities Exchange Act of 1934, as amended,
if, after the transaction, the acquiring person (or persons acting in concert)
owns, controls or holds with power to vote 25% or more of any class of voting
securities of the institution. The acquisition may not be consummated subsequent
to such notice if the Federal Reserve issues a notice within 60 days, or within
certain extensions of such period, disapproving the same.
    
 
   
     The merger or consolidation of an existing bank subsidiary of the Company
with another bank, or the acquisition by such a subsidiary of the assets of
another bank, or the assumption of the deposit and other liabilities by such a
subsidiary requires the prior written approval of the responsible Federal
depository institution regulatory agency under the Bank Merger Act, based upon a
consideration of statutory factors similar to those outlined above with respect
to the BHCA. In addition, in certain such cases an application to, and the prior
approval of, the Federal Reserve under the BHCA and/or the Commissioner under
Michigan banking laws, may be required.
    
 
   
     With certain limited exceptions, the BHCA prohibits bank holding companies
from acquiring direct or indirect ownership or control of voting shares or
assets of any company other than a bank, unless the company involved is engaged
solely in one or more activities which the Federal Reserve has determined to be
closely related to banking or managing or controlling banks. In making this
determination, the Federal Reserve considers various factors, including among
others the financial and managerial resources of the notifying bank holding
company, and the relative public benefits and adverse effects which may be
expected to result from the performance of the activity by an affiliate of such
company. The Federal Reserve may apply different standards to activities
proposed to be commenced de novo and activities commenced by acquisition, in
whole or in part, of a going concern.
    
 
   
     The recent enactment of the Economic Growth and Regulatory Paperwork
Reduction Act of 1996 ("EGRPRA") streamlines the nonbanking activities
application process for well capitalized and well managed bank holding
companies. See "Recent Regulatory Developments." Under EGRPRA, qualified bank
holding companies may commence a regulatory approved nonbanking activity without
prior notice to the Federal Reserve; written notice is merely required within
ten days after commencing the activity. Also, under EGRPRA, the prior notice
period is reduced to 12 days in the event of any nonbanking acquisition or share
purchase, assuming the size of the acquisition does not exceed 10% of
risk-weighted assets of the acquiring bank holding company and the consideration
does not exceed 15% in Tier 1 capital. This prior notice requirement also
applies to commencing a nonbanking activity de novo which has been previously
approved by order of the Federal Reserve, but not yet implemented by
regulations.
    
 
   
     CAPITAL REQUIREMENTS. The Federal Reserve uses capital adequacy guidelines
in its examination and regulation of bank holding companies. If capital falls
below minimum guidelines, a bank holding company may, among other things, be
denied approval to acquire or establish additional banks or non-bank businesses.
    
 
                                       40
<PAGE>   43
 
   
     The Federal Reserve's capital guidelines establish the following minimum
regulatory capital requirements for bank holding companies: (i) a capital
leverage requirement expressed as a percentage of total assets, (ii) a
risk-based requirement expressed as a percentage of total risk-weighted assets,
and (iii) a Tier 1 leverage requirement expressed as a percentage of total
assets. The capital leverage requirement consists of a minimum ratio of total
capital to total assets of 6%, with an expressed expectation that banking
organizations generally should operate above such minimum level. The risk-based
requirement consists of a minimum ratio of total capital to total risk-weighted
assets of 8%, of which at least one-half must be Tier 1 capital (which consists
principally of shareholders' equity). The Tier 1 leverage requirement consists
of a minimum ratio of Tier 1 capital to total assets, less goodwill ("Tier 1
capital leverage ratio") of 3% for the most highly rated companies, with minimum
requirements of 4% to 5% for all others.
    
 
   
     The risk-based and leverage standards presently used by the Federal Reserve
are minimum requirements, and higher capital levels will be required if
warranted by the particular circumstances or risk profiles of individual banking
organizations. Further, any banking organization experiencing or anticipating
significant growth would be expected to maintain capital ratios, including
tangible capital positions (i.e., Tier 1 capital less all intangible assets),
well above the minimum levels. The Federal Reserve has not advised the Company
of any specific minimum Tier 1 capital leverage ratio applicable to it.
    
 
   
     FDICIA requires the federal bank regulatory agencies biennially to review
risk-based capital standards to ensure that they adequately address interest
rate risk, concentration of credit risk and risks from non-traditional
activities and, since adoption of the Riegle Community Development and
Regulatory Improvement Act of 1994 (the "Riegle Act"), to do so taking into
account the size and activities of depository institutions and the avoidance of
undue reporting burdens. See "Recent Regulatory Developments." In 1995, the
federal bank regulatory agencies adopted regulations requiring as part of the
assessment of an institution's capital adequacy the consideration of: (i)
identified concentrations of credit risks, (ii) the exposure of the institution
to a decline in the value of its capital due to changes in interest rates, and
(iii) the application of revised conversion factors and netting rules on the
institution's potential future exposure from derivative transactions.
    
 
   
     DIVIDENDS. The Company is a corporation separate and distinct from the
Banks. Most of the Company's revenues are received by it in the form of
dividends paid by the Banks. The Banks are subject to statutory restrictions on
their ability to pay dividends to the Company. See "The Banks -- Dividends." The
Federal Reserve has issued a policy statement on the payment of cash dividends
by bank holding companies. In the policy statement, the Federal Reserve
expressed its view that a bank holding company experiencing earnings weaknesses
should not pay cash dividends exceeding its net income or which could only be
funded in ways that weakened the bank holding company's financial health, such
as by borrowing. Additionally, the Federal Reserve possesses enforcement powers
over bank holding companies and their non-bank subsidiaries to prevent or remedy
actions that represent unsafe or unsound practices or violations of applicable
statutes and regulations. Among these powers is the ability to proscribe the
payment of dividends by banks and bank holding companies. Similar enforcement
powers over the Banks are possessed by the FDIC. The "prompt corrective action"
provisions of FDICIA impose further restrictions on the payment of dividends by
insured banks which fail to meet specified capital levels and, in some cases,
impose similar restrictions on their parent bank holding companies.
    
 
   
     In addition to the restrictions on dividends imposed by the Federal
Reserve, the Michigan Business Corporation Act provides that dividends may be
legally declared or paid only if after the distribution a corporation, such as
the Company, can pay its debts as they come due in the usual course of business
and its total assets equal or exceed the sum of its liabilities plus the amount
that would be needed to satisfy the preferential rights upon dissolution of any
holders of preferred stock whose preferential rights are superior to those
receiving the distribution.
    
 
THE BANKS
 
     GENERAL. The Banks are Michigan banking corporations and their deposit
accounts are principally insured by the BIF of the FDIC. As BIF-insured Michigan
chartered banks, the Banks are subject to the examination, supervision,
reporting and enforcement requirements of the Commissioner, as the chartering
authority for
 
                                       41
<PAGE>   44
 
Michigan banks, and the FDIC, as administrator of the BIF. These agencies and
federal and state law extensively regulate various aspects of the banking
business including, among other things, permissible types and amounts of loans,
investments and other activities, capital adequacy, branching, interest rates on
loans and on deposits, the maintenance of noninterest-bearing reserves on
deposit accounts, and the safety and soundness of banking practices.
 
   
     DEPOSIT INSURANCE. As FDIC-insured institutions, the Banks are required to
pay deposit insurance premium assessments to the FDIC. Pursuant to FDICIA, the
FDIC adopted a risk-based assessment system under which all insured depository
institutions are placed into one of nine categories and assessed insurance
premiums, based upon their level of capital and supervisory evaluation.
Institutions classified as well-capitalized (as defined by the FDIC) and
considered healthy pay the lowest premium while institutions that are less than
adequately capitalized (as defined by the FDIC) and considered of substantial
supervisory concern pay the highest premium. Risk classification of all insured
institutions is made by the FDIC for each semi-annual assessment period.
    
 
     FDICIA required the FDIC to establish assessment rates at levels which
would restore the BIF to a mandated reserve ratio of 1.25% of insured deposits
over a period not to exceed 15 years. In 1995, the FDIC determined that the BIF
had reached the required ratio. Accordingly, the FDIC has established the
schedule of BIF insurance assessments for the first semi-annual assessment
period of 1996, ranging from 0% of deposits for institutions in the highest
category to .27% of deposits for institutions in the lowest category. For the
first nine months of 1996, the Banks paid $32,000 in BIF insurance assessments.
 
   
     At September 30, 1996, the Banks held less than $11 million of SAIF-insured
deposits, and paid an average rate premium of .23% on such deposits during the
first nine months of 1996. The deposit liabilities to be assumed in connection
with the acquisition of the FOA Branches are all insured by SAIF. Effective
September 30, 1996, the FDIC was authorized to impose a special assessment on
certain SAIF-assessable deposits. Because IBEM held no SAIF-assessable deposits
as of March 31, 1995, IBEM will be exempt from the special assessment.
    
 
   
     The FDIC may terminate the deposit insurance of any insured depository
institution if the FDIC determines, after a hearing, that the institution or its
directors have engaged or are engaging in unsafe or unsound practices, or have
violated any applicable law, regulation, order, or any condition imposed in
writing by, or written agreement with, the FDIC, or if the institution is in an
unsafe or unsound condition to continue operations. The FDIC may also suspend
deposit insurance temporarily during the hearing process for a permanent
termination of insurance if the institution has no tangible capital.
    
 
   
     CAPITAL REQUIREMENTS. Consistent with the Federal Reserve's guidelines for
bank holding companies, the FDIC has established the following minimum capital
standards for state-chartered, FDIC-insured non-member banks, such as the Banks:
a leverage requirement consisting of a minimum ratio of Tier 1 capital to total
assets of 3% for the most highly-rated banks with minimum requirements of 4% to
5% for all others and a risk-based capital requirement consisting of a minimum
ratio of total capital to total risk-weighted assets of 8%, at least one-half of
which must be Tier 1 capital (which consists principally of shareholders'
equity). These capital requirements are minimum requirements. Higher capital
levels will be required if warranted by the particular circumstances or risk
profiles of individual institutions.

     FDICIA establishes five capital categories, and the federal depository
institution regulators, as directed by FDICIA, have adopted, subject to certain
exceptions, the following minimum requirements for each of such categories:

</TABLE>
 
     At September 30, 1996, each of the Banks' ratios exceeded minimum
requirements for the well-capitalized category.
 
   
     Among other things, FDICIA requires the federal depository institution
regulators to take prompt corrective action in respect of depository
institutions that do not meet minimum capital requirements. The scope and degree
of regulatory intervention is linked to the capital category to which a
depository institution is assigned.
    
 
     Depending upon the capital category to which an institution is assigned,
the regulators' corrective powers include: requiring the submission of a capital
restoration plan; placing limits on asset growth and restrictions on activities;
requiring the institution to issue additional capital stock (including
additional voting stock) or to be acquired; restricting transactions with
affiliates; restricting the interest rate the institution may pay on deposits;
ordering a new election of directors of the institution; requiring that senior
executive officers or directors be dismissed; prohibiting the institution from
accepting deposits from correspondent banks; requiring the institution to divest
certain subsidiaries; prohibiting the payment of principal or interest on
subordinated debt; and ultimately, appointing a receiver for the institution.
 
   
     In general, a depository institution may be reclassified to a lower
category than is indicated by its capital position if the appropriate federal
depository institution regulatory agency determines the institution to be
otherwise in an unsafe or unsound condition or to be engaged in an unsafe or
unsound practice. Such a practice could include a failure by the institution,
following receipt of a less-than-satisfactory rating on its most recent
examination report, to correct the deficiency.
    
 
     DIVIDENDS. Under Michigan law, the Banks are restricted as to the maximum
amount of dividends they may pay on their common stock. A Michigan state bank
may not declare or pay a dividend unless the bank will have a surplus amounting
to at least 20% of its capital after the payment of the dividend. A Michigan
state bank may, with the approval of the Commissioner, by vote of shareholders
owning 2/3 of the stock eligible to vote, increase its capital stock by a
declaration of a stock dividend, provided that after the increase the bank's
surplus equals at least 20% of its capital stock, as increased. The Banks may
not declare or pay any dividend until the cumulative dividends on preferred
stock (should any such stock be issued and outstanding) have been paid in full.
The Banks have no present plans to issue preferred stock other than the
Preferred Stock.
 
   
     FDICIA generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository institution would thereafter be
undercapitalized. The FDIC may also prevent an insured bank from paying
dividends if the bank is in default of payment of any assessment due to the
FDIC. In addition, payment of dividends by a bank may be prevented by the
applicable federal regulatory authority if such payment is determined, by reason
of the financial condition of such bank, to be an unsafe and unsound banking
practice. The Federal Reserve Board has issued a policy statement providing that
bank holding companies and insured banks should generally only pay dividends out
of current operating earnings.
    
 
                                       43
<PAGE>   46
 
   
     INSIDER TRANSACTIONS. The Banks are subject to certain restrictions imposed
by the Federal Reserve Act on "covered transactions" with the Company or its
subsidiaries. The "covered transactions" that an insured bank and its
subsidiaries are permitted to engage in with their nonbank affiliates are
limited to the following amounts: (i) in the case of any one such affiliate, the
aggregate amount of "covered transactions" of the insured bank and its
subsidiaries cannot exceed 10% of the capital stock and surplus of the insured
bank; and (ii) in the case of all affiliates, the aggregate amount of all
"covered transactions" of the insured bank and its subsidiaries cannot exceed
20% of the capital stock and surplus of the insured bank. "Covered transactions"
are defined by statute to include a loan or extension of credit to the
affiliate, a purchase of securities issued by an affiliate, a purchase of assets
from the affiliate (unless otherwise exempted by the Federal Reserve), the
acceptance of securities issued by the affiliate as collateral for a loan, and
the issuance of a guaranty, acceptance, or letter of credit for the benefit of
an affiliate. Covered transactions must also be collateralized. The Federal
Reserve Act further requires that (i) "covered transactions" with affiliates;
(ii) asset sales to affiliates; (iii) contractual arrangements with affiliates;
(iv) transactions in which an affiliate acts as an agent or broker; and (v) any
transaction in which an affiliate has a financial interest or is a participant,
must be made: (x) on terms and under circumstances, including credit standards,
that are substantially the same as those prevailing at the time for comparable
transactions with or involving other nonaffiliated companies; or (y) in the
absence of comparable transactions, on terms and under circumstances, including
credit standards, that in good faith would be offered to, or would apply to,
nonaffiliated companies. Certain limitations and reporting requirements are also
placed on extensions of credit by the Banks to their directors and officers, to
directors and officers of the Company and its subsidiaries, to principal
shareholders of the Company, and to "related interests" of such directors,
officers and principal shareholders. In addition, such legislation and
regulations may affect the terms upon which any person becoming a director or
officer of the Company or one of its subsidiaries or a principal shareholder of
the Company may obtain credit from banks with which any of the Banks maintains a
correspondent relationship.
    
 
   
     SAFETY AND SOUNDNESS STANDARDS. On July 10, 1995, the FDIC, the Office of
Thrift Supervision, the Federal Reserve and the Office of the Comptroller of the
Currency published final guidelines implementing the FDICIA requirement that the
federal banking agencies establish operational and managerial standards to
promote the safety and soundness of federally insured depository institutions.
The guidelines, which took effect on August 9, 1995, establish standards for
internal controls, information systems, internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth, and
compensation, fees and benefits. In general, the guidelines prescribe the goals
to be achieved in each area, and each institution is responsible for
establishing its own procedures to achieve those goals. If an institution fails
to comply with any of the standards set forth in the guidelines, the
institution's primary federal regulator may require the institution to submit a
plan for achieving and maintaining compliance. The preamble to the guidelines
states that the agencies expect to require a compliance plan from an institution
whose failure to meet one or more of the standards is of such severity that it
could threaten the safe and sound operation of the institution. Failure to
submit an acceptable compliance plan, or failure to adhere to a compliance plan
that has been accepted by the appropriate regulator, would constitute grounds
for further enforcement action. The federal banking agencies have also published
for comment proposed asset quality and earnings standards which, if adopted,
would be added to the safety and soundness guidelines. This proposal, like the
final guidelines, would make each depository institution responsible for
establishing its own procedures to meet such goals.
    
 
     STATE BANK ACTIVITIES. Under FDICIA, as implemented by final regulations
adopted by the FDIC, FDIC-insured state banks are prohibited, subject to certain
exceptions, from making or retaining equity investments of a type, or in an
amount, that are not permissible for a national bank. FDICIA, as implemented by
FDIC regulations, also prohibits FDIC-insured state banks and their
subsidiaries, subject to certain exceptions, from engaging as a principal in any
activity that is not permitted for a national bank or its subsidiary,
respectively, unless the bank meets, and continues to meet, its minimum
regulatory capital requirements and the FDIC determines the activity would not
pose a significant risk to the deposit insurance fund of which the bank is a
member. Impermissible investments and activities must be divested or
discontinued within certain time frames set by the FDIC in accordance with
FDICIA.

     CONSUMER BANKING. The Banks' business includes making a variety of types of
loans to individuals. In making these loans, the Banks are subject to State
usury and regulatory laws and to various Federal statutes, such as the Equal
Credit Opportunity Act, Fair Credit Reporting Act, Truth in Lending Act, Real
Estate Settlement Procedures Act, and Home Mortgage Disclosure Act, and the
regulations promulgated thereunder, which (x) prohibit discrimination based on
race, color, religion, national origin, sex, marital status, age (except in
limited circumstances), receipt of income from public assistance programs, or
good faith exercise of any rights under the Consumer Credit Protection Act, (y)
specify disclosures to be made to borrowers regarding credit and settlement
costs, and (z) regulate the mortgage loan servicing activities of the Bank,
including the maintenance and operation of escrow accounts and the transfer of
mortgage loan servicing. The Riegle Act imposed new escrow requirements on
mortgage lenders and servicers under the National Flood Insurance Program. See
"Recent Regulatory Developments." In receiving deposits, the Banks are subject
to extensive regulation under state and federal law and regulations, including
the Truth in Savings Act, the Expedited Funds Availability Act, the Bank Secrecy
Act, the Electronic Funds Transfer Act, and the Federal Deposit Insurance Act.
Violation of these laws could result in the imposition of significant damages
and fines upon the Banks and their respective directors and officers.
 
RECENT REGULATORY DEVELOPMENTS
 
   
     In 1994, the Congress enacted two major pieces of banking legislation, the
Riegle Act and the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 (the "Riegle-Neal Act"). The Riegle Act addressed such varied issues as
the promotion of economic revitalization of defined urban and rural "qualified
distressed communities" through special purpose "Community Development Financial
Institutions," the expansion of consumer protection with respect to certain
loans secured by a consumer's home and reverse mortgages, and reductions in
compliance burdens regarding Currency Transaction Reports, reform of the
National Flood Insurance Program, the promotion of a secondary market for small
business loans and leases, and mandating specific changes to reduce regulatory
impositions on depository institutions and holding companies.
    
 
   
     The Riegle-Neal Act substantially changed the geographic constraints
applicable to the banking industry. Effective September 29, 1995, the
Riegle-Neal Act allows bank holding companies to acquire banks located in any
state in the United States without regard to geographic restrictions or
reciprocity requirements imposed by state law, but subject to certain
conditions, including limitations on the aggregate amount of deposits that may
be held by the acquiring holding company and all of its insured depository
institution affiliates. Effective June 1, 1997 (or earlier if expressly
authorized by applicable state law), the Riegle-Neal Act allows banks to
establish interstate branch networks through acquisitions of other banks,
subject to certain conditions that include limitations on the aggregate amount
of deposits that may be held by the surviving bank and all of its insured
depository institution affiliates. The establishment of de novo interstate
branches or the acquisition of individual branches of a bank in another state
(rather than the acquisition of an out-of-state bank in its entirety) is allowed
by the Riegle-Neal Act only if specifically authorized by state law. The
legislation allows individual states to "opt-out" of certain provisions of the
Riegle-Neal Act by enacting appropriate legislation prior to June 1, 1997.
    
 
     In November, 1995, Michigan exercised its right to opt-in early to the
Riegle-Neal Act, and permitted non-U.S. banks to establish branch offices in
Michigan. Effective November 29, 1995, the Michigan Banking Code was amended to
permit, in appropriate circumstances and with the approval of the Commissioner,
(i) the acquisition of Michigan-chartered banks by FDIC-insured banks, savings
banks, or savings and loan associations located in other states, (ii) the sale
by a Michigan-chartered bank of one or more of its branches (not comprising all
or substantially all of its assets) to an FDIC insured bank, savings bank or
savings and loan association located in a state in which a Michigan-chartered
bank could purchase one or more branches of the purchasing entity, (iii) the
acquisition by a Michigan-chartered bank of an FDIC-insured bank, savings bank
or savings and loan association located in another state, (iv) the acquisition
by a Michigan-chartered bank of one or more branches (not comprising all or
substantially all of the assets) of an FDIC-insured bank, savings bank or
savings and loan association located in another state, (v) the consolidation of
one or more Michigan-chartered banks and FDIC-insured banks, savings banks or
savings and loan associations located in
 
                                       45
<PAGE>   48
 
   
other states having laws permitting such consolidation, with the resulting
organization chartered either by Michigan or one of such other states, (vi) the
establishment by Michigan-chartered banks of branches located in other states,
the District of Columbia, or U.S. territories or protectorates with the consent
of the appropriate state or territorial regulatory authority, and (vii) the
establishment by foreign banks of branches located in Michigan. The amending
legislation also expanded the regulatory authority of the Commissioner and made
certain other changes.
    
 
     The Michigan Legislature adopted, effective March 28, 1996, the Credit
Reform Act. This statute, together with amendments to other related laws,
permits regulated lenders, indirectly including Michigan-chartered banks, to
charge and collect higher rates of interest and increased fees on certain types
of loans to individuals and businesses. The laws prohibit "excessive fees and
charges," and authorize governmental authorities and borrowers to bring actions
for injunctive relief and statutory and actual damages for violations by
lenders. The statutes specifically authorize class actions, and also civil money
penalties for knowing and willful, or persistent violations.
 
   
     FDIC regulations which became effective April 1, 1996, impose limitations
(and in certain cases, prohibitions) on (1) certain "golden parachute" severance
payments by troubled depository institutions and their affiliated holding
companies to institution-affiliated parties (primarily directors, officers,
employees, or principal shareholders of the institution), and (ii) certain
indemnification payments by a depository institution or its affiliated holding
company, regardless of financial condition, to institution-affiliated parties.
The FDIC regulations impose limitations on indemnification payments which could
restrict, in certain circumstances, payments by the Company or the Banks to
their respective directors or officers otherwise permitted under the Michigan
Business Corporation Act ("MBCA") or the Michigan Banking Code, respectively.
    
 
   
     On September 30, 1996, EGRPRA was signed into law, which provides for the
recapitalization of SAIF and includes approximately 40 regulatory relief
initiatives. Among other matters, this legislation provides for expedited
application procedures for nonbanking activities by well capitalized and well
managed bank holding companies, provides reforms to the Fair Credit Reporting
Act, and provides other forms of regulatory relief to the financial services
industry.
    
 
   
                      DESCRIPTION OF PREFERRED SECURITIES
    
 
   
     The Preferred Securities will be issued pursuant to the terms of the Trust
Agreement. The Trust Agreement will be qualified as an indenture under the Trust
Indenture Act. Initially, State Street Bank and Trust Company will be the
Property Trustee and will act as trustee for the purpose of complying with the
Trust Indenture Act. The terms of the Preferred Securities will include those
stated in the Trust Agreement and those made part of the Trust Agreement by the
Trust Indenture Act. This summary of certain terms and provisions of the
Preferred Securities and the Trust Agreement does not purport to be complete and
is subject to, and is qualified in its entirety by reference to, all the
provisions of the Trust Agreement, including the definitions therein of certain
terms, and the Trust Indenture Act. Wherever particular defined terms of the
Trust Agreement (as amended or supplemented from time to time) are referred to
herein, such defined terms are incorporated herein. The form of the Trust
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part.
    
 
   
GENERAL
    
 
   
     Pursuant to the terms of the Trust Agreement, the Trustees on behalf of IBC
Capital will issue the Preferred Securities and the Common Securities
(collectively, the "Trust Securities"). The Preferred Securities will represent
preferred beneficial interests in IBC Capital and the holders thereof will be
entitled to a preference in certain circumstances with respect to Distributions
and amounts payable on redemption or liquidation over the Common Securities of
IBC Capital, as well as other benefits as described in the Trust Agreement.
    
 
   
     The Preferred Securities will rank pari passu, and payments will be made
thereon pro rata, with the Common Securities of IBC Capital except as described
under "-- Subordination of Common Securities."
    
 
                                       46
<PAGE>   49
 
   
Legal title to the Subordinated Debentures will be held by the Property Trustee
in trust for the benefit of the holders of the Preferred Securities and Common
Securities. The Guarantee executed by the Company for the benefit of the holders
of the Preferred Securities will be a guarantee on a subordinated basis with
respect to the Preferred Securities but will not guarantee payment of
Distributions or amounts payable on redemption or liquidation of such Preferred
Securities when IBC Capital does not have funds on hand available to make such
payments. See "Description of Guarantee."
    
 
   
DISTRIBUTIONS
    
 
   
     PAYMENT OF DISTRIBUTIONS. The Preferred Securities represent beneficial
interests in IBC Capital, and Distributions on each Preferred Security will be
payable at the annual rate of      % of the stated Liquidation Amount of $25,
payable quarterly in arrears on March 31, June 30, September 30 and December 31
of each year, to the holders of the Preferred Securities on the relevant record
dates (each date on which Distributions are payable in accordance with the
foregoing, a "Distribution Date"). The record date will be, for so long as the
Preferred Securities remain in book-entry form, one Business Day prior to the
relevant Distribution Date and, in the event the Preferred Securities are not in
book-entry form, the 15th day of the month in which the relevant Distribution
Date occurs. Distributions will accumulate from the date of original issuance.
The first Distribution Date for the Preferred Securities will be March 31, 1997.
The amount of Distributions payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months. In the event that any date on which
Distributions are payable on the Preferred Securities is not a Business Day,
then payment of the Distributions payable on such date will be made on the next
succeeding day that is a Business Day (and without any additional Distributions,
interest or other payment in respect of any such delay), in each case with the
same force and effect as if made on the date such payment was originally
payable. As used in this Prospectus, a "Business Day" shall mean any day other
than a Saturday or a Sunday, or a day on which banking institutions in The City
of New York are authorized or required by law or executive order to remain
closed or a day on which the corporate trust office of the Property Trustee or
the Debenture Trustee is closed for business.
    
 
   
     EXTENSION PERIOD. So long as no Event of Default under the Indenture has
occurred and is continuing, the Company has the right under the Indenture to
defer the payment of interest on the Subordinated Debentures at any time or from
time to time for a period not exceeding 20 consecutive quarters with respect to
each such period (each, an "Extension Period"), provided that no Extension
Period may extend beyond the Stated Maturity of the Subordinated Debentures. As
a consequence of any such election, quarterly Distributions on the Preferred
Securities will be deferred by IBC Capital during any such Extension Period.
Distributions to which holders of the Preferred Securities are entitled will
accumulate additional Distributions thereon at the rate per annum of      %
thereof, compounded quarterly from the relevant Distribution Date. The term
"Distributions" as used herein shall include any such additional Distributions.
During any such Extension Period, the Company may not, and may not permit any
subsidiary of the Company to, (i) declare or pay any dividends or distributions
on, or redeem, purchase, acquire or make a liquidation payment with respect to,
any of the Company's capital stock or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Company that rank pari passu with or junior in interest to the
Subordinated Debentures or make any guarantee payments with respect to any
guarantee by the Company of the debt securities of any subsidiary of the Company
if such guarantee ranks pari passu with or junior in interest to the
Subordinated Debentures (other than (a) dividends or distributions in Common
Stock, (b) any declaration of a dividend in connection with the implementation
of a shareholders' rights plan, or the issuance of stock under any such plan in
the future, or the redemption or repurchase of any such rights pursuant thereto,
(c) payments under the Guarantee and (d) purchases of Common Stock under any of
the Company's benefit plans for its directors, officers or employees). Prior to
the termination of any such Extension Period, the Company may defer the payment
of interest, provided that no Extension Period may exceed 20 consecutive
quarters, or extend beyond the Stated Maturity of the Subordinated Debentures.
Upon the termination of any such Extension Period and the payment of all amounts
then due, the Company may elect to begin a new Extension Period. Subject to the
foregoing, there is no limitation on the number of times that the Company may
elect to begin an Extension Period.
    
 
                                       47
<PAGE>   50
 
   
     The Company has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the
Subordinated Debentures.
    
 
   
     CUMULATIVE DISTRIBUTIONS. Distributions on the Preferred Securities will
accumulate from the date of original issuance and will be payable on the
Distribution Dates. In the event that any date on which Distributions are
payable on the Preferred Securities is not a Business Day, then payment of the
Distribution payable on such date will be made on the next succeeding day that
is a Business Day (and without any additional Distributions, interest or other
payment in respect to any such delay) with the same force and effect as if made
on the date such payment was originally payable.
    
 
   
     The funds of IBC Capital available for distribution to holders of its
Preferred Securities will be limited to payments under the Subordinated
Debentures in which IBC Capital will invest the proceeds from the issuance and
sale of its Preferred Securities. See "Description of Subordinated Debentures."
If the Company does not make interest payments on the Subordinated Debentures,
the Property Trustee will not have funds available to pay Distributions on the
Preferred Securities. The payment of Distributions (if and to the extent IBC
Capital has funds legally available for the payment of such Distributions and
cash sufficient to make such payments) is guaranteed by the Company. See
"Description of Guarantee."
    
 
   
     Distributions on the Preferred Securities will be payable to the holders
thereof as they appear on the register of IBC Capital on the relevant record
dates, which, as long as the Preferred Securities remain in book-entry form,
will be one Business Day prior to the relevant Distribution Date. Subject to any
applicable laws and regulations and the provisions of the Trust Agreement, each
such payment will be made as described under "Book-Entry Issuance."
    
 
   
REDEMPTION OR EXCHANGE
    
 
   
     The Company will have the right to redeem the Subordinated Debentures (i)
on or after             , 2001, in whole at any time or in part from time to
time, or (ii) at any time, in whole (but not in part), upon the occurrence of a
Tax Event, in each case subject to receipt of prior approval by the Federal
Reserve if then required under applicable capital guidelines or policies of the
Federal Reserve.
    
 
   
     MANDATORY REDEMPTION. Upon the repayment or redemption, in whole or in
part, of any Subordinated Debentures, whether at Stated Maturity or upon earlier
redemption as provided in the Indenture, the proceeds from such repayment or
redemption shall be applied by the Property Trustee to redeem a Like Amount (as
defined below) of the Trust Securities, upon not less than 30 nor more than 60
days notice, at a redemption price (the "Redemption Price") equal to the
aggregate Liquidation Amount of such Trust Securities plus accumulated but
unpaid Distributions thereon to the date of redemption (the "Redemption Date").
See "Description of Subordinated Debentures -- Redemption or Exchange." If less
than all of the Subordinated Debentures are to be repaid or redeemed on a
Redemption Date, then the proceeds from such repayment or redemption shall be
allocated to the redemption of the Preferred Securities and the Common
Securities pro rata or by lot.
    
 
   
     DISTRIBUTION OF SUBORDINATED DEBENTURES. Subject to the Company having
received prior approval of the Federal Reserve if so required under applicable
capital guidelines or policies of the Federal Reserve, the Company will have the
right at any time to liquidate IBC Capital and, after satisfaction of the
liabilities of creditors of IBC Capital as provided by applicable law, cause the
Subordinated Debentures to be distributed to the holders of Preferred Securities
and Common Securities in liquidation of IBC Capital.

     TAX EVENT REDEMPTION OR INVESTMENT COMPANY EVENT REDEMPTION. If a Tax Event
or an Investment Company Event in respect of the Preferred Securities and Common
Securities shall occur and be continuing, the Company has the right to redeem
the Subordinated Debentures in whole (but not in part) and thereby cause a
mandatory redemption of such Preferred Securities and Common Securities in whole
(but not in part) at the Redemption Price within 90 days following the
occurrence of such Tax Event or Investment Company Event. In the event a Tax
Event or an Investment Company Event in respect of the Preferred Securities and
Common Securities has occurred and is continuing and the Company does not elect
to redeem the Subordinated Debentures and thereby cause a mandatory redemption
of such Preferred Securities and Common Securities or to liquidate IBC Capital
and cause the Subordinated Debentures to be distributed to holders of such
Preferred Securities and Common Securities in liquidation of IBC Capital as
described below, such Preferred Securities will remain outstanding and
Additional Sums (as defined below) may be payable on the Subordinated
Debentures.
    
 
   
     "Additional Sums" means the additional amounts as may be necessary in order
that the amount of Distributions then due and payable by IBC Capital on the
outstanding Preferred Securities and Common Securities of IBC Capital shall not
be reduced as a result of any additional taxes, duties and other governmental
charges to which IBC Capital has become subject as a result of a Tax Event or an
Investment Company Event.
    
 
   
     "Like Amount" means (i) with respect to a redemption of Trust Securities,
Trust Securities having a Liquidation Amount (as defined below) equal to that
portion of the principal amount of Subordinated Debentures to be
contemporaneously redeemed in accordance with the Indenture, allocated to the
Common Securities and to the Preferred Securities based upon the relative
Liquidation Amounts of such classes and the proceeds of which will be used to
pay the Redemption Price of such Trust Securities, and (ii) with respect to a
distribution of Subordinated Debentures to holders of Trust Securities in
connection with a dissolution or liquidation of IBC Capital, Subordinated
Debentures having a principal amount equal to the Liquidation Amount of the
Trust Securities of the holder to whom such Subordinated Debentures are
distributed.
    
 
   
     "Liquidation Amount" means the stated amount of $25 per Trust Security.
    
 
   
     After the liquidation date fixed for any distribution of Subordinated
Debentures for Preferred Securities (i) such Preferred Securities will no longer
be deemed to be outstanding, (ii) The Depository Trust Company (the
"Depositary") or its nominee, as the record holder of the Preferred Securities,
will receive a registered global certificate or certificates representing the
Subordinated Debentures to be delivered upon such distribution and (iii) any
certificates representing Preferred Securities not held by the Depositary or its
nominee will be deemed to represent the Subordinated Debentures having a
principal amount equal to the Liquidation Amount of such Preferred Securities,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid Distributions on the Preferred Securities until such certificates are
presented to the Administrative Trustees or their agent for transfer or
reissuance.
    
 
   
     There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Debentures that may be distributed in exchange
for Preferred Securities if a dissolution and liquidation of IBC Capital were to
occur. Accordingly, the Preferred Securities that an investor may purchase, or
the Subordinated Debentures that the investor may receive on dissolution and
liquidation of IBC Capital, may trade at a discount to the price that the
investor paid to purchase the Preferred Securities offered hereby.
    
 
   
REDEMPTION PROCEDURES
    
 
   
     Preferred Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Subordinated Debentures. Redemptions of the Preferred
Securities shall be made and the Redemption Price shall be payable on each
Redemption Date only to the extent that IBC Capital has funds on hand available
for the payment of such Redemption Price. See "Subordination of Common
Securities."
    
 
                                       49
<PAGE>   52
 
   
     If IBC Capital gives a notice of redemption in respect of its Preferred
Securities, then, by 12:00 noon, eastern standard time, on the Redemption Date,
to the extent funds are available, the Property Trustee will deposit irrevocably
with the Depositary funds sufficient to pay the aggregate Redemption Price and
will give the Depositary irrevocable instructions and authority to pay the
Redemption Price to the holders of such Preferred Securities. See "Book-Entry
Issuance." If such Preferred Securities are no longer in book-entry form, the
Property Trustee, to the extent funds are available, will irrevocably deposit
with the paying agent for such Preferred Securities funds sufficient to pay the
aggregate Redemption Price and will give such paying agent irrevocable
instructions and authority to pay the Redemption Price to the holders thereof
upon surrender of their certificates evidencing such Preferred Securities.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Preferred Securities called for redemption shall be
payable to the holders of such Preferred Securities on the relevant record dates
for the related Distribution Dates. If notice of redemption shall have been
given and funds deposited as required, then upon the date of such deposit, all
rights of the holders of such Preferred Securities so called for redemption will
cease, except the right of the holders of such Preferred Securities to receive
the Redemption Price, but without interest on such Redemption Price, and such
Preferred Securities will cease to be outstanding. In the event that any date
fixed for redemption of Preferred Securities is not a Business Day, then payment
of the Redemption Price payable on such date will be made on the next succeeding
day which is a Business Day (and without any additional Distribution, interest
or other payment in respect of any such delay). In the event that payment of the
Redemption Price in respect of Preferred Securities called for redemption is
improperly withheld or refused and not paid either by IBC Capital or by the
Company pursuant to the Guarantee. Distributions on such Preferred Securities
will continue to accrue at the then applicable rate, from the Redemption Date
originally established by IBC Capital for such Preferred Securities to the date
such Redemption Price is actually paid, in which case the actual payment date
will be the date fixed for redemption for purposes of calculating the Redemption
Price. See "Description of Guarantee."
    
 
   
     Subject to applicable law (including, without limitation, United States
federal securities law), the Company or its subsidiaries may at any time and
from time to time purchase outstanding Preferred Securities by tender, in the
open market or by private agreement.
    
 
   
     Payment of the Redemption Price on the Preferred Securities and any
distribution of Subordinated Debentures to holders of Preferred Securities shall
be made to the applicable recordholders thereof as they appear on the register
for such Preferred Securities on the relevant record date, which date shall be
one Business Day prior to the relevant Redemption Date or liquidation date, as
applicable; provided, however, that in the event that any Preferred Securities
are not in book-entry form, the relevant record date for such Preferred
Securities shall be a date at least 15 days prior to the Redemption Date or
liquidation date, as applicable.
    
 
   
     If less than all of the Preferred Securities and Common Securities issued
by IBC Capital are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of such Preferred Securities and Common Securities to be
redeemed shall be allocated pro rata to the Preferred Securities and the Common
Securities based upon the relative Liquidation Amounts of such classes. The
particular Preferred Securities to be redeemed shall be selected by the Property
Trustee from the outstanding Preferred Securities not previously called for
redemption, by such method as the Property Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $25 or an integral multiple of $25 in excess thereof) of the
Liquidation Amount of Preferred Securities of a denomination larger than $25.
The Property Trustee shall promptly notify the trust registrar in writing of the
Preferred Securities selected for redemption and, in the case of any Preferred
Securities selected for partial redemption, the Liquidation Amount thereof to be
redeemed. For all purposes of the Trust Agreement, unless the context otherwise
requires, all provisions relating to the redemption of Preferred Securities
shall relate to the portion of the aggregate Liquidation Amount of Preferred
Securities which has been or is to be redeemed.
    
 
   
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each Holder of Trust Securities to be
redeemed at its registered address. Unless the Company defaults in payment of
the Redemption Price on the Subordinated Debentures, on and after the
    
 
                                       50
<PAGE>   53
 
   
Redemption Date interest will cease to accrue on such Subordinated Debentures or
portions thereof (and distributions will cease to accrue on the related
Preferred Securities or portions thereof) called for redemption.
    
 
   
SUBORDINATION OF COMMON SECURITIES
    
 
   
     Payment of Distributions on, and the Redemption Price of, the Preferred
Securities and Common Securities, as applicable, shall be made pro rata based on
the Liquidation Amount of the Preferred Securities and Common Securities;
provided, however, that if on any Distribution Date or Redemption Date a
Debenture Event of Default shall have occurred and be continuing, no payment of
any Distribution on, or Redemption Price of, any of the Common Securities, and
no other payment on account of the redemption, liquidation or other acquisition
of such Common Securities, shall be made unless payment in full in cash of all
accumulated and unpaid Distributions on all of the outstanding Preferred
Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all of the outstanding Preferred Securities then called for redemption,
shall have been made or provided for, and all funds available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions on, or Redemption Price of, the Preferred Securities then due and
payable.
    
 
   
     In the case of any Event of Default resulting from a Debenture Event of
Default, the Company as holder of the Common Securities will be deemed to have
waived any right to act with respect to any such Event of Default under the
applicable Trust Agreement until the effect of all such Events of Default with
respect to such Preferred Securities have been cured, waived or otherwise
eliminated. Until any such Events of Default under the Trust Agreement with
respect to the Preferred Securities have been so cured, waived or otherwise
eliminated, the Property Trustee shall act solely on behalf of the holders of
the Preferred Securities and not on behalf of the Company as holder of the
Common Securities, and only the holders of the Preferred Securities will have
the right to direct the Property Trustee to act on their behalf.
    
 
   
LIQUIDATION DISTRIBUTION UPON TERMINATION
    
 
   
     The Company will have the right at any time to terminate IBC Capital and
cause the Subordinated Debentures to be distributed to the holders of the
Preferred Securities. Such right is subject to the Company having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies of the Federal Reserve.
    
 
   
     In addition, pursuant to the Trust Agreement, IBC Capital shall
automatically terminate upon expiration of its term and shall earlier terminate
on the first to occur of: (i) certain events of bankruptcy, dissolution or
liquidation of the Company; (ii) the distribution of a Like Amount of the
Subordinated Debentures to the holders of its Trust Securities, if the Company,
as Depositor, has given written direction to the Property Trustee to terminate
IBC Capital (which direction is optional and wholly within the discretion of the
Company, as Depositor); (iii) redemption of all of the Preferred Securities as
described under "Description of Preferred Securities -- Redemption or
Exchange -- Mandatory Redemption;" and (iv) the entry of an order for the
dissolution of IBC Capital by a court of competent jurisdiction.
    
 
   
     If an early termination occurs as described in clause (i), (ii) or (iv)
above, IBC Capital shall be liquidated by the Trustees as expeditiously as the
Trustees determine to be possible by distributing, after satisfaction of
liabilities to creditors of IBC Capital as provided by applicable law, to the
holders of such Trust Securities a Like Amount of the Subordinated Debentures,
unless such distribution is determined by the Property Trustee not to be
practical, in which event such holders will be entitled to receive out of the
assets of IBC Capital available for distribution to holders, after satisfaction
of liabilities to creditors of IBC Capital as provided by applicable law, an
amount equal to, in the case of holders of Preferred Securities, the aggregate
of the Liquidation Amount plus accrued and unpaid Distributions thereon to the
date of payment (such amount being the "Liquidation Distribution"). If such
Liquidation Distribution can be paid only in part because IBC Capital has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then the amounts payable directly by IBC Capital on the Preferred
Securities shall be paid on a pro rata basis. The holder(s) of the Common
Securities will be entitled to receive distributions upon any such liquidation
pro rata with the
    
 
                                       51
<PAGE>   54
 
   
holders of the Preferred Securities, except that if a Debenture Event of Default
has occurred and is continuing, the Preferred Securities shall have a priority
over the Common Securities.
    
 
   
     Under current United States federal income tax law and interpretations and
assuming, as expected, IBC Capital is treated as a grantor trust, a distribution
of the Subordinated Debentures should not be a taxable event to holders of the
Preferred Securities. Should there be a change in law, a change in legal
interpretation, a Tax Event or other circumstances, however, the distribution
could be a taxable event to holders of the Preferred Securities. See "Certain
Federal Income Tax Consequences." If the Company elects neither to redeem the
Subordinated Debentures prior to maturity nor to liquidate IBC Capital and
distribute the Subordinated Debentures to holders of the Preferred Securities,
the Preferred Securities will remain outstanding until the repayment of the
Subordinated Debentures.
    
 
   
     If the Company elects to liquidate IBC Capital and thereby causes the
Subordinated Debentures to be distributed to holders of the Preferred Securities
in liquidation of IBC Capital, the Company shall continue to have the right to
shorten or extend the maturity of such Subordinated Debentures, subject to
certain conditions. See "Description of Subordinated Debentures -- General."
    
 
   
LIQUIDATION VALUE
    
 
   
     The amount payable on the Preferred Securities in the event of any
liquidation of IBC Capital is $25 per Preferred Security plus accrued and unpaid
Distributions thereon to the date of payment, which may be in the form of a
distribution of such amount in Subordinated Debentures, subject to certain
exceptions. See "Description of Preferred Securities -- Liquidation Distribution
Upon Termination."
    
 
   
EVENTS OF DEFAULT; NOTICE
    
 
   
     Any one of the following events constitutes an "Event of Default" under the
Trust Agreement (an "Event of Default") with respect to the Preferred Securities
(whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):
    
 
   
          (i) the occurrence of a Debenture Event of Default under the Indenture
     (see "Description of Subordinated Debentures -- Debenture Events of
     Default"); or
    
 
   
          (ii) default by the Property Trustee in the payment of any
     Distribution when it becomes due and payable, and continuation of such
     default for a period of 30 days; or
    
 
   
          (iii) default by the Property Trustee in the payment of any Redemption
     Price of any Trust Security when it becomes due and payable; or
    
 
   
          (iv) default in the performance, or breach, in any material respect,
     of any covenant or warranty of the Trustees in the Trust Agreement (other
     than a covenant or warranty a default in the performance of which or the
     breach of which is dealt with in clauses (ii) or (iii) above), and
     continuation of such default or breach for a period of 60 days after there
     has been given, by registered or certified mail, to the Trustee or Trustees
     by the holders of at least 25% in aggregate Liquidation Amount of the
     outstanding Preferred Securities, a written notice specifying such default
     or breach and requiring it to be remedied and stating that such notice is a
     "Notice of Default" under the Trust Agreement; or
    
 
   
          (v) the occurrence of certain events of bankruptcy or insolvency with
     respect to the Property Trustee and the failure by the Company to appoint a
     successor Property Trustee within 60 days thereof.
    
 
   
     Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit
notice of such Event of Default to the holders of the Preferred Securities, the
Administrative Trustees and the Company, as Depositor, unless such Event of
Default shall
    
 
                                       52
<PAGE>   55
 
   
have been cured or waived. The Company, as Depositor, and the Administrative
Trustees are required to file annually with the Property Trustee a certificate
as to whether or not they are in compliance with all the conditions and
covenants applicable to them under each Trust Agreement.
    
 
   
     If a Debenture Event of Default has occurred and is continuing, the
Preferred Securities shall have a preference over the Common Securities upon
termination of IBC Capital as described above. See "-- Liquidation Distribution
Upon Termination." The existence of an Event of Default does not entitle the
holders of Preferred Securities to accelerate the maturity thereof.
    
 
   
REMOVAL OF IBC CAPITAL TRUSTEES
    
 
   
     Unless a Debenture Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by the holder of the Common Securities.
If a Debenture Event of Default has occurred and is continuing, the Property
Trustee and the Delaware Trustee may be removed at such time by the holders of a
majority in Liquidation Amount of the outstanding Preferred Securities. In no
event will the holders of the Preferred Securities have the right to vote to
appoint, remove or replace the Administrative Trustees, which voting rights are
vested exclusively in the Company as the holder of the Common Securities. No
resignation or removal of a Trustee and no appointment of a successor trustee
shall be effective until the acceptance of appointment by the successor trustee
in accordance with the provisions of the applicable Trust Agreement.
    
 
   
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
    
 
   
     Unless an Event of Default shall have occurred and be continuing, at any
time or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Company, as the holder of the Common Securities, and
the Administrative Trustees shall have power to appoint one or more persons
either to act as a co-trustee, jointly with the Property Trustee, of all or any
part of such Trust Property, or to act as separate trustee of any such property,
in either case with such powers as may be provided in the instrument of
appointment, and to vest in such person or persons in such capacity any
property, title, right or power deemed necessary or desirable, subject to the
provisions of the applicable Trust Agreement. In case a Debenture Event of
Default has occurred and is continuing, the Property Trustee alone shall have
power to make such appointment.
    
 
   
MERGER OR CONSOLIDATION OF TRUSTEES
    
 
   
     Any person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any person resulting from any merger,
conversion or consolidation to which such Trustee shall be a party, or any
person succeeding to all or substantially all the corporate trust business of
such Trustee, shall be the successor of such Trustee under each Trust Agreement,
provided such person shall be otherwise qualified and eligible.
    
 
   
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF IBC CAPITAL
    
 
   
     IBC Capital may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below. IBC Capital may, at the request of the Company, with the
consent of the Administrative Trustees and without the consent of the holders of
the Preferred Securities, merge with or into, consolidate, amalgamate, or be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to a trust organized as such under the laws of any State;
provided, that (i) such successor entity either (a) expressly assumes all of the
obligations of IBC Capital with respect to the Preferred Securities or (b)
substitutes for the Preferred Securities other securities having substantially
the same terms as the Preferred Securities (the "Successor Securities") so long
as the Successor Securities rank the same as the Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption
and otherwise, (ii) the Company expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee in its
capacity as the holder of the Subordinated Debentures, (iii) the Successor
Securities are listed, or any Successor Securities will be listed upon
notification of issuance,
    
 
                                       53
<PAGE>   56
 
   
on the Nasdaq National Market or any national securities exchange or other
organization on which the Preferred Securities are then listed, if any, (iv)
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
holders of the Preferred Securities (including any Successor Securities) in any
material respect, (v) such successor entity has a purpose identical to that of
IBC Capital, (vi) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Company has received an opinion
from independent counsel to IBC Capital experienced in such matters to the
effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Preferred Securities (including any
Successor Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
IBC Capital nor such successor entity will be required to register as an
investment company under the Investment Company Act of 1940, as amended (the
"Investment Company Act") and (vii) the Company or any permitted successor or
assignee owns all of the common securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Guarantee. Notwithstanding the
foregoing, IBC Capital shall not, except with the consent of holders of 100% in
Liquidation Amount of the Preferred Securities, consolidate, amalgamate, merge
with or into, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to any other entity or permit any other
entity to consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or lease
would cause IBC Capital or the successor entity to be classified as other than a
grantor trust for United States federal income tax purposes.
    
 
   
VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT
    
 
   
     Except as provided below and under "Description of Guarantee -- Amendments
and Assignment" and as otherwise required by law and the Trust Agreement, the
holders of the Preferred Securities will have no voting rights.
    
 
   
     The Trust Agreement may be amended from time to time by the Company, the
Property Trustee and the Administrative Trustees, without the consent of the
holders of the Preferred Securities (i) to cure any ambiguity, correct or
supplement any provisions in such Trust Agreement that may be inconsistent with
any other provision, or to make any other provisions with respect to matters or
questions arising under the Trust Agreement, which shall not be inconsistent
with the other provisions of the Trust Agreement, or (ii) to modify, eliminate
or add to any provisions of the Trust Agreement to such extent as shall be
necessary to ensure that IBC Capital will be classified for United States
federal income tax purposes as a grantor trust at all times that any Trust
Securities are outstanding or to ensure that IBC Capital will not be required to
register as an "investment company" under the Investment Company Act; provided,
however, that in the case of clause (i), such action shall not adversely affect
in any material respect the interests of any holder of Trust Securities, and any
amendments of such Trust Agreement shall become effective when notice thereof is
given to the holders of Trust Securities. The Trust Agreement may be amended by
the Trustees and the Company with (i) the consent of holders representing not
less than a majority in the aggregate Liquidation Amount of the outstanding
Trust Securities, and (ii) receipt by the Trustees of an opinion of counsel to
the effect that such amendment or the exercise of any power granted to the
Trustees in accordance with such amendment will not affect IBC Capital's status
as a grantor trust for United States federal income tax purposes or IBC
Capital's exemption from status as an "investment company" under the Investment
Company Act, provided that without the consent of each holder of Trust
Securities, such Trust Agreement may not be amended to (i) change the amount or
timing of any Distribution on the Trust Securities or otherwise adversely affect
the amount of any Distribution required to be made in respect of the Trust
Securities as of a specified date or (ii) restrict the right of a holder of
Trust Securities to institute suit for the enforcement of any such payment on or
after such date.
    
 
   
     So long as any Subordinated Debentures are held by the Property Trustee,
the Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Property Trustee with respect to the
Subordinated Debentures, (ii) waive any past default that is waivable under the
Indenture, (iii) exercise any right to rescind
    
 
                                       54
<PAGE>   57
 
   
or annul a declaration that the principal of all the Subordinated Debentures
shall be due and payable or (iv) consent to any amendment, modification or
termination of the Indenture or the Subordinated Debentures, where such consent
shall be required, without, in each case, obtaining the prior approval of the
holders of a majority in aggregate Liquidation Amount of all outstanding
Preferred Securities; provided, however, that where a consent under the
Indenture would require the consent of each holder of Subordinated Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior consent of each holder of the Preferred Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the holders
of the Preferred Securities except by subsequent vote of the holders of the
Preferred Securities. The Property Trustee shall notify each holder of Preferred
Securities of any notice of default with respect to the Subordinated Debentures.
In addition to obtaining the foregoing approvals of the holders of the Preferred
Securities, prior to taking any of the foregoing actions, the Trustees shall
obtain an opinion of counsel experienced in such matters to the effect that IBC
Capital will not be classified as an association taxable as a corporation for
United States federal income tax purposes on account of such action.
    
 
   
     Any required approval of holders of Preferred Securities may be given at a
meeting of holders of Preferred Securities convened for such purpose or pursuant
to written consent. The Property Trustee will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be given
to each holder of record of Preferred Securities in the manner set forth in the
Trust Agreement.
    
 
   
     No vote or consent of the holders of Preferred Securities will be required
for IBC Capital to redeem and cancel its Preferred Securities in accordance with
the Trust Agreement.
    
 
   
     Notwithstanding the fact that holders of Preferred Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned by the Company, the Trustees or any
affiliate of the Company or any Trustee, shall, for purposes of such vote or
consent, be treated as if they were not outstanding.
    
 
   
GLOBAL PREFERRED SECURITIES
    
 
   
     The Preferred Securities will be represented by one or more global
certificates registered in the name of the Depositary or its nominee ("Global
Preferred Security"). Beneficial interests in the Preferred Securities will be
shown on, and transfers thereof will be effected only through, records
maintained by participants in the Depositary. Except as described below,
Preferred Securities in certificated form will not be issued in exchange for the
global certificates. See "Book-Entry Issuance."
    
 
   
     A global security shall be exchangeable for Preferred Securities registered
in the names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as a
depositary for such global security and no successor depositary shall have been
appointed, or if at any time the Depositary ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, as amended, at a time when
the Depositary is required to be so registered to act as such depositary, (ii)
the Company in its sole discretion determines that such global security shall be
so exchangeable, or (iii) there shall have occurred and be continuing an Event
of Default under the Indenture. Any global security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for definitive
certificates registered in such names as the Depositary shall direct. It is
expected that such instructions will be based upon directions received by the
Depositary with respect to ownership of beneficial interests in such global
security. In the event that Preferred Securities are issued in definitive form,
such Preferred Securities will be in denominations of $25 and integral multiples
thereof and may be transferred or exchanged at the offices described below.
    
 
   
     Unless and until it is exchanged in whole or in part for the individual
Preferred Securities represented thereby, a Global Preferred Security may not be
transferred except as a whole by the Depositary to a nominee of such Depositary
or by a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by the Depositary or any nominee to a successor Depositary or any
nominee of such successor.
    
 
                                       55
<PAGE>   58
 
   
     Payments on Preferred Securities represented by a global security will be
made to the Depositary, as the depositary for the Preferred Securities. In the
event Subordinated Debentures are issued in definitive form, principal and
Distributions will be payable, the transfer of the Preferred Securities will be
registrable, and Preferred Securities will be exchangeable for Preferred
Securities of other denominations of a like aggregate Liquidation Amount, at the
corporate office of the Property Trustee in Boston, Massachusetts, or at the
offices of any paying agent or transfer agent appointed by the Administrative
Trustees, provided that payment of any Distribution may be made at the option of
the Administrative Trustees by check mailed to the address of the persons
entitled thereto or by wire transfer. In addition, if the Preferred Securities
are issued in certificated form, the record dates for payment of Distributions
will be the 15th day of the month in which the relevant Distribution Date
occurs. For a description of the terms of the depositary arrangements relating
to payments, transfers, voting rights, redemptions and other notices and other
matters, see "Book-Entry Issuance."
    
 
   
     Upon the issuance of a Global Preferred Security, and the deposit of such
Global Preferred Security with or on behalf of the Depositary, the Depositary
for such Global Preferred Security or its nominee will credit, on its book-entry
registration and transfer system, the respective aggregate Liquidation Amounts
of the individual Preferred Securities represented by such Global Preferred
Securities to the accounts of Participants. Such accounts shall be designated by
the dealers, underwriters or agents with respect to such Preferred Securities.
Ownership of beneficial interests in a Global Preferred Security will be limited
to Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Preferred Security will be
shown on, and the transfer of that ownership will be effected only through,
records maintained by the applicable Depositary or its nominee (with respect to
interests of Participants) and the records of Participants (with respect to
interests of persons who hold through Participants). The laws of some states
require that certain purchasers of securities take physical delivery of such
securities in definitive form. Such limits and such laws may impair the ability
to transfer beneficial interests in a Global Preferred Security.
    
 
   
     So long as the Depositary for a Global Preferred Security, or its nominee,
is the registered owner of such Global Preferred Security, such Depositary or
such nominee, as the case may be, will be considered the sole owner or holder of
the Preferred Securities represented by such Global Preferred Security for all
purposes under the Indenture governing such Preferred Securities. Except as
provided below, owners of beneficial interests in a Global Preferred Security
will not be entitled to have any of the individual Preferred Securities
represented by such Global Preferred Security registered in their names, will
not receive or be entitled to receive physical delivery of any such Preferred
Securities in definitive form and will not be considered the owners or holders
thereof under the Indenture.
    
 
   
     None of the Company, the Property Trustee, any Paying Agent, or the
Securities Registrar for such Preferred Securities will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Global Preferred Security
representing such Preferred Securities or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
    
 
   
     The Company expects that the Depositary for Preferred Securities or its
nominee, upon receipt of any payment of the Liquidation Amount or Distributions
in respect of a permanent Global Preferred Security immediately will credit
Participants' accounts with payments in amounts proportionate to their
respective beneficial interest in the aggregate Liquidation Amount of such
Global Preferred Security as shown on the records of such Depositary or its
nominee. The Company also expects that payments by Participants to owners of
beneficial interests in such Global Preferred Security held through such
Participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name." Such payments will be the responsibility of
such Participants.
    
 
   
     If the Depositary for the Preferred Securities is at any time unwilling,
unable or ineligible to continue as depositary and a successor depositary is not
appointed by the Company within 90 days, IBC Capital will issue individual
Preferred Securities in exchange for the Global Preferred Security. In addition,
IBC Capital may at any time and in its sole discretion, subject to any
limitations described herein relating to such Preferred Securities, determine
not to have any Preferred Securities represented by one or more Global Preferred
    
 
                                       56
<PAGE>   59
 
   
Securities and, in such event, will issue individual Preferred Securities in
exchange for the Global Preferred Security or Securities representing the
Preferred Securities. Further, if IBC Capital so specifies with respect to the
Preferred Securities, an owner of a beneficial interest in a Global Preferred
Security representing Preferred Securities may, on terms acceptable to the
Company, the Property Trustee and the Depositary for such Global Preferred
Security, receive individual Preferred Securities in exchange for such
beneficial interests, subject to any limitations described herein. In any such
instance, an owner of a beneficial interest in a Global Preferred Security will
be entitled to physical delivery of individual Preferred Securities represented
by such Global Preferred Security equal in Liquidation Amount to such beneficial
interest and to have such Preferred Securities registered in its name.
Individual Preferred Securities so issued will be issued in denominations,
unless otherwise specified by IBC Capital, of $25 and integral multiples
thereof.
    
 
   
PAYMENT AND PAYING AGENCY
    
 
   
     Payments in respect of the Preferred Securities shall be made to the
Depositary, which shall credit the relevant accounts at the Depositary on the
applicable Distribution Dates or, if any Preferred Securities are not held by
the Depositary, such payments shall be made by check mailed to the address of
the holder entitled thereto as such address shall appear on the Register. The
paying agent ("Paying Agent") shall initially be the Property Trustee and any
copaying agent chosen by the Property Trustee and acceptable to the
Administrative Trustees and the Company. The Paying Agent shall be permitted to
resign as Paying Agent upon 30 days' written notice to the Property Trustee and
the Company. In the event that the Property Trustee shall no longer be the
Paying Agent, the Administrative Trustees shall appoint a successor (which shall
be a bank or trust company acceptable to the Administrative Trustees and the
Company) to act as Paying Agent.
    
 
   
REGISTRAR AND TRANSFER AGENT
    
 
   
     The Property Trustee will act as registrar and transfer agent for the
Preferred Securities. Registration of transfers of Preferred Securities will be
effected without charge by or on behalf of IBC Capital, but upon payment of any
tax or other governmental charges that may be imposed in connection with any
transfer or exchange. IBC Capital will not be required to register or cause to
be registered the transfer of Preferred Securities after such Preferred
Securities have been called for redemption.
    
 
   
INFORMATION CONCERNING THE PROPERTY TRUSTEE
    
 
   
     The Property Trustee, other than upon the occurrence and during the
continuance of an Event of Default, undertakes to perform only such duties as
are specifically set forth in the Trust Agreement and, after such Event of
Default, must exercise the same degree of care and skill as a prudent person
would exercise or use in the conduct of his or her own affairs. Subject to this
provision, the Property Trustee is under no obligation to exercise any of the
powers vested in it by the Trust Agreement at the request of any holder of
Preferred Securities unless it is offered reasonable indemnity against the
costs, expenses and liabilities that might be incurred thereby. If no Event of
Default has occurred and is continuing and the Property Trustee is required to
decide between alternative causes of action, construe ambiguous provisions in
the applicable Trust Agreement or is unsure of the application of any provision
of the Trust Agreement, and the matter is not one on which holders of Preferred
Securities are entitled under the Trust Agreement to vote, then the Property
Trustee shall take such action as is directed by the Company and if not so
directed, shall take such action as it deems advisable and in the best interests
of the holders of the Trust Securities and will have no liability except for its
own bad faith, negligence or willful misconduct.
    
 
   
MISCELLANEOUS
    
 
   
     The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate IBC Capital in such a way that IBC Capital will not be
deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as an association taxable as a corporation
for United States federal income tax purposes and so that the Subordinated
Debentures will be treated as indebtedness of the Company for United States
federal income tax purposes. In this connection, the Company and the
Administrative Trustees are authorized to take any action, not inconsistent with
applicable law, the
    
 
                                       57
<PAGE>   60
 
   
certificate of trust of IBC Capital or the Trust Agreement, that the Company and
the Administrative Trustees determine in their discretion to be necessary or
desirable for such purposes, as long as such action does not materially
adversely affect the interests of the holders of the related Preferred
Securities.
    
 
   
     Holders of the Preferred Securities have no preemptive or similar rights.
    
 
   
                     DESCRIPTION OF SUBORDINATED DEBENTURES
    
 
   
     The Subordinated Debentures will be issued under the Indenture, dated as of
            , 1996 ("Indenture"), between the Company and State Street Bank and
Trust Company, as trustee ("Debenture Trustee"). The following summary of the
terms and provisions of the Subordinated Debentures and the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the Indenture, which has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part, and to the Trust
Indenture Act. The Indenture is qualified under the Trust Indenture Act.
Whenever particular defined terms of the Indenture are referred to herein, such
defined terms are incorporated herein or therein by reference.
    
 
   
     Concurrently with the issuance of the Preferred Securities, IBC Capital
will invest the proceeds thereof, together with the consideration paid by the
Company for the Common Securities, in the Subordinated Debentures issued by the
Company. The Subordinated Debentures will be issued as unsecured debt under the
Indenture.
    
 
   
GENERAL
    
 
   
     The Subordinated Debentures will bear interest at the annual rate of      %
of the principal amount thereof, payable quarterly in arrears on March 31, June
30, September 30, and December 31 of each year (each, an "Interest Payment
Date") beginning March 31, 1997, to the person in whose name each Subordinated
Debenture is registered, subject to certain exceptions, at the close of business
on the Business Day next preceding such Interest Payment Date. It is anticipated
that, until the liquidation, if any, of IBC Capital, the Subordinated Debentures
will be held in the name of the Property Trustee in trust for the benefit of the
holders of the Preferred Securities. The amount of interest payable for any
period will be computed on the basis of a 360-day year of twelve 30-day months.
In the event that any date on which interest is payable on the Subordinated
Debentures is not a Business Day, then payment of the interest payable on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other payment in respect of any such delay) with the same force
and effect as if made on the date such payment was originally payable. Accrued
interest that is not paid on the applicable Interest Payment Date will bear
additional interest on the amount thereof (to the extent permitted by law) at
the rate per annum of      % thereof, compounded quarterly. The term "interest"
as used herein shall include quarterly interest payments, interest on quarterly
interest payments not paid on the applicable Interest Payment Date and
Additional Sums (as defined below), as applicable.
    
 
   
     The Subordinated Debentures will mature on             , 2026 (such date,
as it may be shortened or extended as hereinafter described, the "Stated
Maturity"). Such date may be shortened at any time by the Company to any date
not earlier than             , 2001, subject to the Company having received
prior approval of the Federal Reserve if then required under applicable capital
guidelines or policies of the Federal Reserve. Such date may also be extended at
any time at the election of the Company but in no event to a date later than
            , 2045, provided that at the time such election is made and at the
time of extension (i) the Company is not in bankruptcy, otherwise insolvent or
in liquidation, (ii) the Company is not in default in the payment of any
interest or principal on the Subordinated Debentures, and (iii) IBC Capital is
not in arrears on payments of Distributions on the Preferred Securities and no
deferred Distributions are accumulated. In the event that the Company elects to
shorten or extend the Stated Maturity of the Subordinated Debentures, it shall
give notice to the Debenture Trustee, and the Debenture Trustee shall give
notice of such shortening or extension to the holders of the Subordinated
Debentures no more than 180 days and no less than 90 days prior to the
effectiveness thereof.
    
 
                                       58
<PAGE>   61
 
   
     The Subordinated Debentures will be unsecured and will rank junior and be
subordinate in right of payment to all Senior Debt and Subordinated Debt of the
Company and, in certain circumstances relating to the dissolution, winding-up,
liquidation or reorganization of the Company, to all Additional Senior
obligations of the Company. See "Description of Subordinated Debentures --
Subordination." Because the Company is a holding company, the right of the
Company to participate in any distribution of assets of any of the Banks, upon
any such Bank's liquidation or reorganization or otherwise (and thus the ability
of holders of the Preferred Securities to benefit indirectly from such
distribution), is subject to the prior claim of creditors of that Bank, except
to the extent that the Company may itself be recognized as a creditor of such
Bank. Accordingly, the Subordinated Debentures will be effectively subordinated
to all existing and future liabilities of the Banks, and holders of Subordinated
Debentures should look only to the assets of the Company for payments on the
Subordinated Debentures. The Indenture does not limit the incurrence or issuance
of other secured or unsecured debt of the Company, including Senior Debt,
Subordinated Debt, Additional Senior Obligations, whether under the Indenture or
any existing indenture or other indenture that the Company may enter into in the
future or otherwise. See "Description of Subordinated Debentures --
Subordination."
    
 
   
OPTION TO EXTEND INTEREST PAYMENT PERIOD
    
 
   
     So long as no Event of Default under the Indenture has occurred or is
continuing, the Company has the right under the Indenture at any time during the
term of the Subordinated Debentures to defer the payment of interest at any time
or from time to time for a period not exceeding 20 consecutive quarters (each
such period an "Extension Period"), provided that no Extension Period may extend
beyond the Stated Maturity of the Preferred Securities. At the end of such
Extension Period, the Company must pay all interest then accrued and unpaid
(together with interest thereon at the annual rate of    %, compounded
quarterly, to the extent permitted by applicable law). During an Extension
Period, interest will continue to accrue and holders of Subordinated Debentures
(or holders of Preferred Securities while such series is outstanding) will be
required to accrue interest income for United States federal income tax
purposes. See "Certain Federal Income Tax Consequences -- Potential Extension of
Interest Payment Period and Original Issue Discount."
    
 
   
     During any such Extension Period, the Company may not, and may not permit
any Bank or other subsidiary of the Company to, (i) declare or pay any dividends
or distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Company's capital stock or (ii) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Company (including other Subordinated Debentures) that
rank pari passu with or junior in interest to the Subordinated Debentures or
make any guarantee payments with respect to any guarantee by the Company of the
debt securities of any subsidiary of the Company if such guarantee ranks pari
passu or junior in interest to the Subordinated Debentures (other than (a)
dividends or distributions in Common Stock, (b) any declaration of a dividend in
connection with the implementation of a shareholders' rights plan, or the
issuance of stock under any such plan in the future or the redemption or
repurchase of any such rights pursuant thereto, (c) payments under the
Guarantee, and (d) purchases of Common Stock related to rights under any of the
Company's benefit plans for its directors, officers or employees). Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period may exceed 20
consecutive quarters or extend beyond the Stated Maturity of the Subordinated
Debentures. Upon the termination of any such Extension Period and the payment of
all amounts then due on any Interest Payment Date, the Company may elect to
begin a new Extension Period subject to the above requirements. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Company must give the Property Trustee, the Administrative Trustees and the
Debenture Trustee notice of its election of such Extension Period at least one
Business Day prior to the earlier of (i) the date the Distributions on the
Preferred Securities would have been payable except for the election to begin
such Extension Period or (ii) the date the Administrative Trustees are required
to give notice to the Nasdaq National Market or other applicable self-regulatory
organization, or to holders of such Preferred Securities on the record date for
the date such Distributions are payable, but in any event not less than one
Business Day prior to such record date. The Debenture Trustee shall give notice
of the Company's election to begin a new Extension Period to the holders of the
Preferred Securities. There is no limitation on the number of times that the
Company may elect to begin an Extension Period.

ADDITIONAL SUMS
    
 
   
     If IBC Capital is required to pay any additional taxes, duties or other
governmental charges as a result of a Tax Event, the Company will pay as
additional amounts on the Subordinated Debentures such amounts ("Additional
Sums") as shall be required so that the Distributions payable by IBC Capital
shall not be reduced as a result of any such additional taxes, duties or other
governmental charges.
    
 
   
REDEMPTION OR EXCHANGE
    
 
   
     Subject to the Company having received prior approval of the Federal
Reserve, if then required under applicable capital guidelines or policies of the
Federal Reserve, the Subordinated Debentures are redeemable prior to maturity at
the option of the Company (i) on or after             , 2001, in whole at any
time or in part from time to time or (ii) at any time in whole (but not in
part), upon the occurrence and during the continuance of a Debenture Tax Event
or an Investment Company Event in each case at a redemption price equal to the
accrued and unpaid interest on the Subordinated Debentures so redeemed to the
date fixed for redemption, plus 100% of the principal amount thereof.
    
 
   
     "Debenture Tax Event" means the receipt by the Company of an opinion of
counsel experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced prospective change) in, the
laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
which pronouncement or decision is announced on or after the date of issuance of
the Subordinated Debentures under the Indenture, there is more than an
insubstantial risk that (i) interest payable by the Company on the Subordinated
Debentures is not, or within 90 days of the date of such opinion will not be,
deductible by the Company, in whole or in part, for United States federal income
tax purposes, (ii) IBC Capital is, or will be within 90 days after the date of
such opinion of counsel, subject to United States federal income tax with
respect to income received or accrued on the Subordinated Debentures, or (iii)
IBC Capital is, or will be within 90 days after the date of such opinion of
counsel, subject to more than a de minimis amount of other taxes, duties,
assessments or other governmental charges.
    
 
   
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Subordinated Debentures to
be redeemed at its registered address. Unless the Company defaults in payment of
the redemption price, on and after the redemption date interest ceases to accrue
on such Subordinated Debentures or portions thereof called for redemption.
    
 
   
     The Subordinated Debentures will not be subject to any sinking fund.
    
 
   
DISTRIBUTION UPON LIQUIDATION
    
 
   
     As described under "Description of Preferred Securities--Liquidation
Distribution Upon Termination," under certain circumstances involving the
termination of IBC Capital, the Subordinated Debentures may be distributed to
the holders of the Preferred Securities in liquidation of IBC Capital after
satisfaction of liabilities to creditors of IBC Capital as provided by
applicable law. If distributed to holders of Preferred Securities in
liquidation, the Subordinated Debentures will initially be issued in the form of
one or more global securities and the Depositary, or any successor depositary
for the Preferred Securities, will act as depositary for the Subordinated
Debentures. It is anticipated that the depositary arrangements for the
Subordinated Debentures would be substantially identical to those in effect for
the Preferred Securities. If the Subordinated Debentures are distributed to the
holders of Preferred Securities upon the liquidation of IBC Capital, the Company
will use its best efforts to list the Subordinated Debentures on the Nasdaq
National Market or such stock exchanges, if any, on which the Preferred
Securities are then listed. There can be no assurance as to the market price of
any Subordinated Debentures that may be distributed to the holders of Preferred
Securities.
    
 
   
RESTRICTIONS ON CERTAIN PAYMENTS
    
 
   
     The Company will covenant, as to the Subordinated Debentures, that if at
such time (i) there shall have occurred any event of which the Company has
actual knowledge that (a) with the giving of notice or the lapse
    
 
                                       60
<PAGE>   63
 
   
of time, or both, would constitute an "Event of Default" under the Indenture
with respect to the Subordinated Debentures of IBC Capital, or (b) in respect of
which the Company shall not have taken reasonable steps to cure, or (ii) the
Company shall have given notice of its election of an Extension Period as
provided in the Indenture with respect to the Subordinated Debentures and shall
not have rescinded such notice, or such Extension Period, or any extension
thereof, shall be continuing. It will not, and will not permit any subsidiary of
the Company to, (1) declare or pay any dividends or distributions on, or redeem,
purchase, acquire, or make a liquidation payment with respect to, any of the
Company's capital stock or (2) make any payment of principal, interest or
premium, if any, on or repay or repurchase or redeem any debt securities of the
Company that rank pari passu with or junior in interest to the Subordinated
Debentures or make any guarantee payments with respect to any guarantee by the
Company of the debt securities of any subsidiary of the Company if such
guarantee ranks pari passu or junior in interest to the Subordinated Debentures
(other than (a) dividends or distributions in Common Stock, (b) any declaration
of a dividend in connection with the implementation of a shareholders' rights
plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, (c) payments under
the Guarantee and (d) purchases of Common Stock related to rights under any of
the Company's benefit plans for its directors, officers or employees.
    
 
   
SUBORDINATION
    
 
   
     In the Indenture, the Company has covenanted and agreed that any
Subordinated Debentures issued thereunder will be subordinate and junior in
right of payment to all Senior Debt, Subordinated Debt and Additional Senior
Obligations to the extent provided in the Indenture. Upon any payment or
distribution of assets to creditors upon any liquidation, dissolution, winding
up, reorganization, assignment for the benefit of creditors, marshaling of
assets or any bankruptcy, insolvency, debt restructuring or similar proceedings
in connection with any insolvency or bankruptcy proceeding of the Company, the
holders of Senior Debt, Subordinated Debt and Additional Senior Obligations will
first be entitled to receive payment in full of principal of (and premium, if
any) and interest, if any, on such Senior Debt, Subordinated Debt and Additional
Senior Obligations before the holders of Subordinated Debentures will be
entitled to receive or retain any payment in respect of the principal of or
interest, if any, on the Subordinated Debentures.
    
 
   
     In the event of the acceleration of the maturity of any Subordinated
Debentures, the holders of all Senior Debt, Subordinated Debt and Additional
Senior Obligations outstanding at the time of such acceleration will first be
entitled to receive payment in full of all amounts due thereon (including any
amounts due upon acceleration) before the holders of Subordinated Debentures
will be entitled to receive or retain any payment in respect of the principal of
or interest, if any, on the Subordinated Debentures; provided, however, that
holders of Subordinated Debt shall not be entitled to receive payment of any
such amounts to the extent that such Subordinated Debt is by its terms
subordinated to trade creditors.
    
 
   
     No payments on account of principal or interest, if any, in respect of the
Subordinated Debentures may be made if there shall have occurred and be
continuing a default in any payment with respect to Senior Debt, Subordinated
Debt or Additional Senior Obligations or an event of default with respect to any
Senior Debt, Subordinated Debt or Additional Senior Obligations resulting in the
acceleration of the maturity thereof, or if any judicial proceeding shall be
pending with respect to any such default.
    
 
   
     "Debt" means with respect to any person, whether recourse is to all or a
portion of the assets of such person and whether or not contingent, (i) every
obligation of such person for money borrowed; (ii) every obligation of such
person evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses; (iii) every reimbursement obligation of such person with
respect to letters of credit, bankers' acceptances or similar facilities issued
for the account of such person; (iv) every obligation of such person issued or
assumed as the deferred purchase price of property or services (but excluding
trade accounts payable or accrued liabilities arising in the ordinary course of
business); (v) every capital lease obligation of such person; and (vi) and every
obligation of the type referred to in clauses (i) through (v) of another person
and all dividends of another person the payment of which, in either case, such
person has guaranteed or is responsible or liable, directly or indirectly, as
obligor or otherwise.
    
 
                                       61
<PAGE>   64
 
   
     "Senior Debt" means the principal of (and premium, if any) and interest, if
any (including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to the Company whether or not such
claim for post-petition interest is allowed in such proceeding), on Debt,
whether incurred on or prior to the date of the Indenture or thereafter
incurred, unless, in the instrument creating or evidencing the same or pursuant
to which the same is outstanding, it is provided that such obligations are not
superior in right of payment to the Subordinated Debentures or to other Debt
which is pari passu with, or subordinated to, the Subordinated Debentures;
provided, however, that Senior Debt shall not be deemed to include (i) any Debt
of the Company which when incurred and without respect to any election under
section 1111(b) of the United States Bankruptcy Code of 1978, as amended, was
without recourse to the Company, (ii) any Debt of the Company to any of its
subsidiaries, (iii) Debt to any employee of the Company, (iv) Debt which by its
terms is subordinated to trade accounts payable or accrued liabilities arising
in the ordinary course of business to the extent that payments made to the
holders of such Debt by the holders of the Subordinated Debentures as a result
of the subordination provisions of the Indenture would be greater than they
otherwise would have been as a result of any obligation of such holders to pay
amounts over to the obligees on such trade accounts payable or accrued
liabilities arising in the ordinary course of business as a result of
subordination provisions to which such Debt is subject; (v) Debt which
constitutes Subordinated Debt, and (vi) any other debt securities issued
pursuant to the Indenture.
    
 
   
     "Subordinated Debt" means the principal of (and premium, if any) and
interest, if any (including interest accruing on or after the filing of any
petition in bankruptcy or for reorganization relating to the Company whether or
not such claim for post-petition interest is allowed in such proceeding), on
Debt, whether incurred on or prior to the date of the Indenture or thereafter
incurred, which is by its terms expressly provided to be junior and subordinate
to other Debt of the Company (other than the Subordinated Debentures).
    
 
   
     "Additional Senior Obligations" means all indebtedness of the Company
whether incurred on or prior to the date of the Indenture or thereafter
incurred, for claims in respect of derivative products such as interest and
foreign exchange rate contracts, commodity contracts and similar arrangements;
provided, however, that Additional Senior Obligations do not include claims in
respect of Senior Debt or Subordinated Debt or obligations which, by their
terms, are expressly stated to be not superior in right of payment to the
Subordinated Debentures or to rank pari passu in right of payment with the
Subordinated Debentures. For purposes of this definition, "claim" shall have the
meaning assigned thereto in Section 101(4) of the United States Bankruptcy Code
of 1978, as amended.
    
 
   
     The Indenture places no limitation on the amount of additional Senior Debt
that may be incurred by the Company. The Company expects from time to time to
incur additional indebtedness constituting Senior Debt, Subordinated Debt and
Additional Senior Obligations.
    
 
   
DENOMINATIONS, REGISTRATION AND TRANSFER
    
 
   
     The Subordinated Debentures will be represented by global certificates
registered in the name of the Depositary or its nominee. Beneficial interests in
the Subordinated Debentures will be shown on, and transfers thereof will be
effected only through, records maintained by the Depositary. Except as described
below, Subordinated Debentures in certificated form will not be issued in
exchange for the global certificates. See "Book-Entry Issuance."
    
 
   
     Unless and until a Global Subordinated Debenture is exchanged in whole or
in part for the individual Subordinated Debentures represented thereby, it may
not be transferred except as a whole by the Depositary for such Global
Subordinated Debenture to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by the
Depositary or any nominee to a successor Depositary or any nominee of such
successor.
    
 
   
     A global security shall be exchangeable for Subordinated Debentures
registered in the names of persons other than the Depositary or its nominee only
if (i) the Depositary notifies the Company that it is unwilling or unable to
continue as a depositary for such global security and no successor depositary
shall have been appointed, or if at any time the Depositary ceases to be a
clearing agency registered under the Securities
    
 
                                       62
<PAGE>   65
 
   
Exchange Act of 1934, as amended, at a time when the Depositary is required to
be so registered to act as such depositary, (ii) the Company in its sole
discretion determines that such global security shall be so exchangeable or
(iii) there shall have occurred and be continuing an Event of Default under the
Indenture with respect to such global security. Any global security that is
exchangeable pursuant to the preceding sentence shall be exchangeable for
definitive certificates registered in such names as the Depositary shall direct.
It is expected that such instructions will be based upon directions received by
the Depositary from its Participants with respect to ownership of beneficial
interests in such global security. In the event that Subordinated Debentures are
issued in definitive form, such Subordinated Debentures will be in denominations
of $25 and integral multiples thereof and may be transferred or exchanged at the
offices described below.
    
 
   
     Payments on Subordinated Debentures represented by a global security will
be made to the Depositary, as the depositary for the Subordinated Debentures. In
the event Subordinated Debentures are issued in definitive form, principal and
interest will be payable, the transfer of the Subordinated Debentures will be
registrable, and Subordinated Debentures will be exchangeable for Subordinated
Debentures of other denominations of a like aggregate principal amount, at the
corporate office of the Debenture Trustee in Boston, Massachusetts, or at the
offices of any paying agent or transfer agent appointed by the Company (the
"Place of Payment"), provided that payment of interest may be made at the option
of the Company by check mailed to the address of the persons entitled thereto or
by wire transfer. In addition, if the Subordinated Debentures are issued in
certificated form, the record dates for payment of interest will be the 15th day
of the last month of each calendar quarter. For a description of the Depositary
and the terms of the depositary arrangements relating to payments, transfers,
voting rights, redemptions and other notices and other matters, see "Book-Entry
Issuance."
    
 
   
     The Company will appoint the Debenture Trustee as securities registrar
under the Indenture (the "Securities Registrar"). Subordinated Debentures may be
presented for exchange as provided above, and may be presented for registration
of transfer (with the form of transfer endorsed thereon, or a satisfactory
written instrument of transfer, duly executed), at the office of the Securities
Registrar. The Company may at any time rescind the designation of any such
transfer agent or approve a change in the location through which any such
transfer agent acts, provided that the Company maintains a transfer agent in the
Place of Payment. The Company may at any time designate additional transfer
agents with respect to the Subordinated Debentures.
    
 
   
     In the event of any redemption, neither the Company nor the Debenture
Trustee shall be required to (i) issue, register the transfer of or exchange
Subordinated Debentures during a period beginning at the opening of business 15
days before the day of selection for redemption of Subordinated Debentures and
ending at the close of business on the day of mailing of the relevant notice of
redemption or (ii) transfer or exchange any Subordinated Debentures so selected
for redemption, except, in the case of any Subordinated Debentures being
redeemed in part, any portion thereof not to be redeemed.
    
 
   
GLOBAL SUBORDINATED DEBENTURES
    
 
   
     Upon the issuance of the Global Subordinated Debenture, and the deposit of
such Global Subordinated Debenture with or on behalf of the Depositary, the
Depositary for such Global Subordinated Debenture or its nominee will credit, on
its book-entry registration and transfer system, the respective principal
amounts of the individual Subordinated Debentures represented by such Global
Subordinated Debenture to the accounts of persons that have accounts with such
Depositary ("Participants"). Ownership of beneficial interests in a Global
Subordinated Debenture will be limited to Participants or persons that may hold
interests through Participants. Ownership of beneficial interests in such Global
Subordinated Debenture will be shown on, and the transfer of that ownership will
be effected only through, records maintained by the applicable Depositary or its
nominee (with respect to interests of Participants) and the records of
Participants (with respect to interests of persons who hold through
Participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Subordinated Debenture.
    
 
   
     So long as the Depositary for a Global Subordinated Debenture, or its
nominee, is the registered owner of such Global Subordinated Debenture, such
Depositary or such nominee, as the case may be, will be
    
 
                                       63
<PAGE>   66
 
   
considered the sole owner or holder of the Subordinated Debentures represented
by such Global Subordinated Debenture for all purposes under the Indenture
governing such Subordinated Debentures. Except as provided below, owners of
beneficial interests in a Global Subordinated Debenture will not be entitled to
have any of the individual Subordinated Debentures represented by such Global
Subordinated Debenture registered in their names, will not receive or be
entitled to receive physical delivery of any such Subordinated Debentures in
definitive form and will not be considered the owners or holders thereof under
the Indenture.
    
 
   
     Payments of principal of and interest on individual Subordinated Debentures
represented by a Global Subordinated Debenture registered in the name of the
Depositary or its nominee will be made to the Depositary or its nominee, as the
case may be, as the registered owner of the Global Subordinated Debenture
representing such Subordinated Debentures. None of the Company, the Debenture
Trustee, any Paying Agent, or the Securities Registrar for such Subordinated
Debentures will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the Global Subordinated Debenture representing such Subordinated
Debentures or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
    
 
   
     The Company expects that the Depositary or its nominee, upon receipt of any
payment of principal, premium or interest in respect of a permanent Global
Subordinated Debenture representing the Subordinated Debentures, immediately
will credit Participants' accounts with payments in amounts proportionate to
their respective beneficial interest in the principal amount of the Global
Subordinated Debenture as shown on the records of such Depositary or its
nominee. The Company also expects that payments by Participants to owners of
beneficial interests in such Global Subordinated Debenture held through such
Participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name." Such payments will be the responsibility of
such Participants.
    
 
   
     If the Depositary is at any time unwilling, unable or ineligible to
continue as depositary and a successor depositary is not appointed by the
Company within 90 days, the Company will issue individual Subordinated
Debentures in exchange for the Global Subordinated Debenture. In addition, the
Company may at any time and in its sole discretion, determine not to have the
Subordinated Debentures represented by one or more Global Subordinated
Debentures and, in such event, will issue individual Subordinated Debentures in
exchange for the Global Subordinated Debenture. Further, if the Company so
specifies with respect to the Subordinated Debentures, an owner of a beneficial
interest in a Global Subordinated Debenture representing Subordinated Debentures
may, on terms acceptable to the Company, the Debenture Trustee and the
Depositary for such Global Subordinated Debenture, receive individual
Subordinated Debentures in exchange for such beneficial interests. In any such
instance, an owner of a beneficial interest in a Global Subordinated Debenture
will be entitled to physical delivery of individual Subordinated Debentures
equal in principal amount to such beneficial interest and to have such
Subordinated Debentures registered in its name. Individual Subordinated
Debentures so issued will be issued in denominations, unless otherwise specified
by the Company, of $25 and integral multiples thereof.
    
 
   
PAYMENT AND PAYING AGENTS
    
 
   
     Payment of principal of and any interest on the Subordinated Debentures
will be made at the office of the Debenture Trustee in the City of Boston,
Massachusetts, except that at the option of the Company payment of any interest
may be made (i) except in the case of Global Subordinated Debentures, by check
mailed to the address of the person entitled thereto as such address shall
appear in the securities register or (ii) by transfer to an account maintained
by the person entitled thereto as specified in the securities register, provided
that proper transfer instructions have been received by the regular record date.
Payment of any interest on Subordinated Debentures will be made to the person in
whose name such Subordinated Debenture is registered at the close of business on
the regular record date for such interest, except in the case of Defaulted
Interest. The Company may at any time designate additional Paying Agents or
rescind the designation of any Paying Agent; however the Company will at all
times be required to maintain a Paying Agent in each Place of Payment for the
Subordinated Debentures.
    
 
                                       64
<PAGE>   67
 
   
     Any moneys deposited with the Debenture Trustee or any Paying Agent, or
then held by the Company in trust, for the payment of the principal of or
interest on the Subordinated Debentures and remaining unclaimed for two years
after such principal or interest has become due and payable shall, at the
request of the Company, be repaid to the Company and the holder of such
Subordinated Debenture shall thereafter look, as a general unsecured creditor,
only to the Company for payment thereof.
    
 
   
MODIFICATION OF INDENTURE
    
 
   
     From time to time the Company and the Debenture Trustee may, without the
consent of the holders of the Subordinated Debentures, amend, waive or
supplement the Indenture for specified purposes, including, among other things,
curing ambiguities, defects or inconsistencies (provided that any such action
does not materially adversely affect the interests of the holders of the
Subordinated Debentures or the Preferred Securities so long as they remain
outstanding) and qualifying, or maintaining the qualification of, the Indenture
under the Trust Indenture Act. The Indenture contains provisions permitting the
Company and the Debenture Trustee, with the consent of the holders of not less
than a majority in principal amount of the outstanding Subordinated Debentures,
to modify the Indenture in a manner affecting the rights of the holders of the
Subordinated Debentures; provided, that no such modification may, without the
consent of the holder of each outstanding Subordinated Debenture, (i) change the
Stated Maturity of the Subordinated Debentures, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon or
(ii) reduce the percentage of principal amount of Subordinated Debentures, the
holders of which are required to consent to any such modification of the
Indenture, provided that so long as any of the Preferred Securities remain
outstanding, no such modification may be made that adversely affects the holders
of such Preferred Securities in any material respect, and no termination of the
Indenture may occur, and no waiver of any Debenture Event of Default or
compliance with any covenant under the Indenture may be effective, without the
prior consent of the holders of at least a majority of the aggregate Liquidation
Amount of the Preferred Securities unless and until the principal of the
Subordinated Debentures and all accrued and unpaid interest thereon have been
paid in full and certain other conditions are satisfied.
    
 
   
DEBENTURE EVENTS OF DEFAULT
    
 
   
     The Indenture provides that any one or more of the following described
events with respect to the Subordinated Debentures that has occurred and is
continuing constitutes a "Debenture Event of Default" with respect to the
Subordinated Debentures:
    
 
   
          (i) failure for 30 days to pay any interest on the Subordinated
     Debentures, when due (subject to the deferral of any due date in the case
     of an Extension Period); or
    
 
   
          (ii) failure to pay any principal on the Subordinated Debentures when
     due whether at maturity, upon redemption by declaration or otherwise; or
    
 
   
          (iii) failure to observe or perform in any material respect certain
     other covenants contained in the Indenture for 90 days after written notice
     to the Company from the Debenture Trustee or the holders of at least 25% in
     aggregate outstanding principal amount of the Subordinated Debentures; or
    
 
   
          (iv) certain events in bankruptcy, insolvency or reorganization of the
     Company.
    
 
   
     The holders of a majority in aggregate outstanding principal amount of the
Subordinated Debentures have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee. The
Debenture Trustee or the holders of not less than 25% in aggregate outstanding
principal amount of the Subordinated Debentures may declare the principal due
and payable immediately upon a Debenture Event of Default. The holders of a
majority in aggregate outstanding principal amount of the Subordinated
Debentures may annul such declaration and waive the default if the default
(other than the non-payment of the principal of the Subordinated Debentures
which has become due solely by such acceleration) has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee.
Should the holders of the
    
 
                                       65
<PAGE>   68
 
   
Subordinated Debentures fail to annul such declaration and waive such default,
the holders of a majority in aggregate Liquidation Amount of the Preferred
Securities shall have such right.
    
 
   
     The Company is required to file annually with the Debenture Trustee a
certificate as to whether or not the Company is in compliance with all the
conditions and covenants applicable to it under the Indenture.
    
 
   
     In case a Debenture Event of Default shall occur and be continuing as to
the Subordinated Debentures, the Property Trustee will have the right to declare
the principal of and the interest on such Subordinated Debentures, and any other
amounts payable under the Indenture, to be forthwith due and payable and to
enforce its other rights as a creditor with respect to such Subordinated
Debentures.
    
 
   
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
    
 
   
     If a Debenture Event of Default has occurred and is continuing and such
event is attributable to the failure of the Company to pay interest or principal
on the Subordinated Debentures on the date such interest or principal is
otherwise payable, a holder of Preferred Securities may institute a legal
proceeding directly against the Company for enforcement of payment to such
holder of the principal of or interest on such Subordinated Debentures having a
principal amount equal to the aggregate Liquidation Amount of the Preferred
Securities of such holder ("Direct Action"). The Company may not amend the
Indenture to remove the foregoing right to bring a Direct Action without the
prior written consent of the holders of all of the Preferred Securities. If the
right to bring a Direct Action is removed, IBC Capital may become subject to the
reporting obligations under the Securities Exchange Act of 1934, as amended. The
Company shall have the right under the Indenture to set-off any payment made to
such holder of Preferred Securities by the Company in connection with a Direct
Action.
    
 
   
     The holders of the Preferred Securities would not be able to exercise
directly any remedies other than those set forth in the preceding paragraph
available to the holders of the Subordinated Debentures unless there shall have
been an Event of Default under the Trust Agreement. See "Description of
Preferred Securities -- Events of Default; Notice."
    
 
   
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
    
 
   
     The Indenture provides that the Company shall not consolidate with or merge
into any other Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, and no Person shall consolidate with
or merge into the Company or convey, transfer or lease its properties and assets
substantially as an entirety to the Company, unless (i) in case the Company
consolidates with or merges into another Person or conveys or transfers its
properties and assets substantially as an entirety to any Person, the successor
Person is organized under the laws of the United States or any state or the
District of Columbia, and such successor Person expressly assumes the Company's
obligations on the Subordinated Debentures issued under the Indenture; (ii)
immediately after giving effect thereto, no Debenture Event of Default, and no
event which, after notice or lapse of time or both, would become a Debenture
Event of Default, shall have occurred and be continuing; and (iii) certain other
conditions as prescribed in the Indenture are met.
    
 
   
     The general provisions of the Indenture do not afford holders of the
Subordinated Debentures protection in the event of a highly leveraged or other
transaction involving the Company that may adversely affect holders of the
Subordinated Debentures.
    
 
   
SATISFACTION AND DISCHARGE
    
 
   
     The Indenture provides that when, among other things, all Subordinated
Debentures not previously delivered to the Debenture Trustee for cancellation
(i) have become due and payable or (ii) will become due and payable at their
Stated Maturity within one year, and the Company deposits or causes to be
deposited with the Debenture Trustee trust funds, in trust, for the purpose and
in an amount in the currency or currencies in which the Subordinated Debentures
are payable sufficient to pay and discharge the entire indebtedness on the
Subordinated Debentures not previously delivered to the Debenture Trustee for
cancellation, for the principal and interest to the date of the deposit or to
the Stated Maturity, as the case may
    
 
                                       66
<PAGE>   69
 
   
be, then the Indenture will cease to be of further effect (except as to the
Company's obligations to pay all other sums due pursuant to the Indenture and to
provide the officers' certificates and opinions of counsel described therein),
and the Company will be deemed to have satisfied and discharged the Indenture.
    
 
   
GOVERNING LAW
    
 
   
     The Indenture and the Subordinated Debentures will be governed by and
construed in accordance with the laws of the State of Michigan.
    
 
   
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
    
 
   
     The Debenture Trustee shall have and be subject to all the duties and
responsibilities specified with respect to an indenture trustee under the Trust
Indenture Act. Subject to such provisions, the Debenture Trustee is under no
obligation to exercise any of the powers vested in it by the Indenture at the
request of any holder of Subordinated Debentures, unless offered reasonable
indemnity by such holder against the costs, expenses and liabilities which might
be incurred thereby. The Debenture Trustee is not required to expend or risk its
own funds or otherwise incur personal financial liability in the performance of
its duties if the Debenture Trustee reasonably believes that repayment or
adequate indemnity is not reasonably assured to it.
    
 
   
     The Company will covenant in the Indenture, as to the Subordinated
Debentures, that if and so long as (i) IBC Capital is the holder of all such
Subordinated Debentures, (ii) a Tax Event in respect of IBC Capital has occurred
and is continuing and (iii) the Company has elected, and has not revoked such
election, to pay Additional Sums (as defined under "Description of Preferred
Securities -- Redemption or Exchange") in respect of the Preferred Securities,
the Company will pay to IBC Capital such Additional Sums. The Company will also
covenant, as to the Subordinated Debentures, (i) to maintain directly or
indirectly 100% ownership of the Common Securities of IBC Capital to which
Subordinated Debentures have been issued, provided that certain successors which
are permitted pursuant to the Indenture may succeed to the Company's ownership
of the Common Securities, (ii) not to voluntarily terminate, wind up or
liquidate IBC Capital, except upon prior approval of the Federal Reserve if then
so required under applicable capital guidelines or policies of the Federal
Reserve, and (a) in connection with a distribution of Subordinated Debentures to
the holders of the Preferred Securities in liquidation of IBC Capital, or (b) in
connection with certain mergers, consolidations or amalgamations permitted by
the related Trust Agreement and (iii) to use its reasonable efforts, consistent
with the terms and provisions of the related Trust Agreement, to cause IBC
Capital to remain classified as a grantor trust and not as an association
taxable as a corporation for United States federal income tax purposes.
    
 
   
                              BOOK-ENTRY ISSUANCE
    
 
   
     The Depositary will act as securities depositary for all of the Preferred
Securities and the Subordinated Debentures. The Preferred Securities and the
Subordinated Debentures will be issued only as fully-registered securities
registered in the name of Cede & Co. (the Depositary's nominee). One or more
fully-registered global certificates will be issued for the Preferred Securities
and the Subordinated Debentures and will be deposited with the Depositary.
    
 
   
     The Depositary is a limited purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The Depositary holds securities that its Participants deposit with the
Depositary. The Depositary also facilitates the settlement among Participants of
securities transactions, such as transfers and pledges, in deposited securities
through electronic computerized book-entry changes in Participants' accounts,
thereby eliminating the need for physical movement of securities certificates.
"Direct Participants" include securities brokers and dealers, banks, trust
companies, clearing corporations and certain other organizations. The Depositary
is owned by a number of its Direct Participants and by the New York Stock
Exchange, Inc., the American Stock Exchange, Inc. and the National Association
of Securities Dealers, Inc. Access to the the Depositary system is also
    
 
                                       67
<PAGE>   70
 
   
available to others such as securities brokers and dealers, banks and trust
companies that clear through or maintain custodial relationships with Direct
Participants, either directly or indirectly ("Indirect Participants"). The rules
applicable to the Depositary and its Participants are on file with the
Commission.
    
 
   
     Purchases of Preferred Securities or Subordinated Debentures within the
Depositary system must be made by or through Direct Participants, which will
receive a credit for the Preferred Securities or Subordinated Debentures on the
Depositary's records. The ownership interest of each actual purchaser of each
Preferred Security and each Subordinated Debenture ("Beneficial Owner") is in
turn to be recorded on the Direct and Indirect Participants' records. Beneficial
Owners will not receive written confirmation from the Depositary of their
purchases, but Beneficial Owners are expected to receive written confirmations
providing details of the transactions, as well as periodic statements of their
holdings, from the Direct or Indirect Participants through which the Beneficial
Owners purchased Preferred Securities or Subordinated Debentures. Transfers of
ownership interests in the Preferred Securities or Subordinated Debentures are
to be accomplished by entries made on the books of Participants acting on behalf
of Beneficial Owners. Beneficial Owners will not receive certificates
representing their ownership interests in Preferred Securities or Subordinated
Debentures, except in the event that use of the book-entry system for the
Preferred Securities of IBC Capital or Subordinated Debentures is discontinued.
    
 
   
     The Depositary has no knowledge of the actual Beneficial Owners of the
Preferred Securities or Subordinated Debentures; the Depositary's records
reflect only the identity of the Direct Participants to whose accounts such
Preferred Securities or Subordinated Debentures are credited, which may or may
not be the Beneficial Owners. The Participants will remain responsible for
keeping account of their holdings on behalf of their customers.
    
 
   
     Conveyance of notices and other communications by the Depositary to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners and the voting
rights of Direct Participants, Indirect Participants and Beneficial Owners will
be governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.
    
 
   
     Redemption notices will be sent to Cede & Co. as the registered holder of
the Preferred Securities or Subordinated Debentures. If less than all of the
Preferred Securities or the Subordinated Debentures are being redeemed, the
Depositary will determine by lot or pro rata the amount of the Preferred
Securities of each Direct Participant to be redeemed.
    
 
   
     Although voting with respect to the Preferred Securities or the
Subordinated Debentures is limited to the holders of record of the Preferred
Securities or Subordinated Debentures, in those instances in which a vote is
required, neither the Depositary nor Cede & Co. will itself consent or vote with
respect to Preferred Securities or Subordinated Debentures. Under its usual
procedures, the Depositary would mail an omnibus proxy (the "Omnibus Proxy") to
the relevant Trustee as soon as possible after the record date. The Omnibus
Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts such Preferred Securities or Subordinated
Debentures are credited on the record date (identified in a listing attached to
the Omnibus Proxy).
    
 
   
     Distribution payments on the Preferred Securities or the Subordinated
Debentures will be made by the relevant Trustee to the Depositary. The
Depositary's practice is to credit Direct Participants' accounts on the relevant
payment date in accordance with their respective holdings shown on the
Depositary's records unless the Depositary has reason to believe that it will
not receive payments on such payment date. Payments by Participants to
Beneficial Owners will be governed by standing instructions and customary
practices and will be the responsibility of such Participant and not of the
Depositary, the relevant Trustee, IBC Capital or the Company, subject to any
statutory or regulatory requirements as may be in effect from time to time.
Payment of Distributions to the Depositary is the responsibility of the relevant
Trustee, disbursement of such payments to Direct Participants is the
responsibility of the Depositary, and disbursements of such payments to the
Beneficial Owners is the responsibility of Direct and Indirect Participants.
    
 
                                       68
<PAGE>   71
 
   
     The Depositary may discontinue providing its services as securities
depositary with respect to any of the Preferred Securities or the Subordinated
Debentures at any time by giving reasonable notice to the relevant Trustee and
the Company. In the event that a successor securities depositary is not
obtained, definitive Preferred Security or Subordinated Debenture certificates
representing such Preferred Securities or Subordinated Debentures are required
to be printed and delivered. The Company, at its option, may decide to
discontinue use of the system of book-entry transfers through the Depositary (or
a successor depositary). After a Debenture Event of Default, the holders of a
majority in liquidation preference of Preferred Securities or aggregate
principal amount of Subordinated Debentures may determine to discontinue the
system of book-entry transfers through the Depositary. In any such event,
definitive certificates for such Preferred Securities or Subordinated Debentures
will be printed and delivered.
    
 
   
     The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that IBC Capital
and the Company believe to be accurate, but IBC Capital and the Company assume
no responsibility for the accuracy thereof. Neither IBC Capital nor the Company
has any responsibility for the performance by the Depositary or its Participants
of their respective obligations as described herein or under the rules and
procedures governing their respective operations.
    
 
   
                            DESCRIPTION OF GUARANTEE
    
 
   
     The Preferred Securities Guarantee Agreement (the "Guarantee") will be
executed and delivered by the Company concurrently with the issuance of the
Preferred Securities for the benefit of the holders of the Preferred Securities.
State Street Bank and Trust Company will act as indenture trustee ("Guarantee
Trustee") under the Guarantee for the purposes of compliance with the Trust
Indenture Act, and the Guarantee will be qualified as an Indenture under the
Trust Indenture Act. The following summary of certain provisions of the
Guarantee does not purport to be complete and is subject to, and qualified in
its entirety by reference to, all of the provisions of the Guarantee Agreement,
including the definitions therein of certain terms, and the Trust Indenture Act.
The form of the Guarantee has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part. The Guarantee Trustee will hold
the Guarantee for the benefit of the holders of the Preferred Securities.
    
 
   
GENERAL
    
 
   
     The Guarantee will be an irrevocable guarantee on a subordinated basis of
IBC Capital's obligations under the Preferred Securities, but will apply only to
the extent that IBC Capital has funds sufficient to make such payments, and is
not a guarantee of collection.
    
 
   
     The Company will irrevocably agree to pay in full on a subordinated basis,
to the extent set forth herein, the Guarantee Payments (as defined below) to the
holders of the Preferred Securities, as and when due, regardless of any defense,
right of set-off or counterclaim that IBC Capital may have or assert other than
the defense of payment. The following payments with respect to the Preferred
Securities, to the extent not paid by or on behalf of IBC Capital (the
"Guarantee Payments"), will be subject to the Guarantee: (i) any accumulated and
unpaid Distributions required to be paid on the Preferred Securities, to the
extent that IBC Capital has funds on hand available therefor at such time, (ii)
the Redemption Price with respect to any Preferred Securities called for
redemption to the extent that IBC Capital has funds on hand available therefor
at such time, and (iii) upon a voluntary or involuntary dissolution, winding up
or liquidation of IBC Capital (unless the Subordinated Debentures are
distributed to holders of the Preferred Securities), the lesser of (a) the
Liquidation Distribution and (b) the amount of assets of IBC Capital remaining
available for distribution to holders of Preferred Securities. The Company's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Company to the holders of the Preferred Securities or by
causing IBC Capital to pay such amounts to such holders.
    
 
   
     If the Company does not make interest payments on the Subordinated
Debentures held by IBC Capital, IBC Capital will not be able to pay
Distributions on the Preferred Securities and will not have funds legally
available therefor. The Guarantee will rank subordinate and junior in right of
payment to all Senior Debt, Subordinated Debt, and, under certain circumstances,
Additional Senior Obligations of the Company. See "-- Status of the Guarantee."
Because the Company is a holding company, the right of the Company to
    
 
                                       69
<PAGE>   72
 
   
participate in any distribution of assets of any subsidiary upon such
subsidiary's liquidation or reorganization or otherwise, is subject to the prior
claims of creditors of that subsidiary, except to the extent the Company may
itself be recognized as a creditor of that subsidiary. Accordingly, the
Company's obligations under the Guarantee will be effectively subordinated to
all existing and future liabilities of the Company's subsidiaries, and claimants
should look only to the assets of the Company for payments thereunder. Except as
otherwise described herein, the Guarantee does not limit the incurrence or
issuance of other secured or unsecured debt of the Company, including Senior
Debt, whether under the Indenture, any other indenture that the Company may
enter into in the future, or otherwise.
    
 
   
     The Company has, through the Guarantee, the Trust Agreement, the
Subordinated Debentures, the Indenture and the Expense Agreement, taken
together, fully, irrevocably and unconditionally guaranteed all of IBC Capital's
obligations under the Preferred Securities. No single document standing alone or
operating in conjunction with fewer than all of the other documents constitutes
such guarantee. It is only the combined operation of these documents that has
the effect of providing a full, irrevocable and unconditional guarantee of IBC
Capital's obligations under the Preferred Securities. See "Relationship Among
the Preferred Securities, the Subordinated Debentures and the Guarantee."
    
 
   
STATUS OF THE GUARANTEE
    
 
   
     The Guarantee will constitute an unsecured obligation of the Company and
will rank subordinate and junior in right of payment to all Senior Debt,
Subordinated Debt and, under certain circumstances, Additional Senior
Obligations of the Company in the same manner as the Subordinated Debentures.
    
 
   
     The Guarantee will constitute a guarantee of payment and not of collection.
For example, the guaranteed party may institute a legal proceeding directly
against the Company to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity. The Guarantee
will be held for the benefit of the holders of the related Preferred Securities.
The Guarantee will not be discharged except by payment of the Guarantee Payments
in full to the extent not paid by IBC Capital or upon distribution of the
Subordinated Debentures to the holders of the Preferred Securities. The
Guarantee does not place a limitation on the amount of additional Senior Debt,
Subordinated Debt or Additional Senior Obligations that may be incurred by the
Company. The Company expects from time to time to incur additional indebtedness
constituting Senior Debt, Subordinated Debt and Additional Senior Obligations.
    
 
   
AMENDMENTS AND ASSIGNMENT
    
 
   
     Except with respect to any changes which do not materially adversely affect
the rights of holders of the related Preferred Securities (in which case no vote
will be required), the Guarantee may not be amended without the prior approval
of the holders of not less than a majority of the aggregate Liquidation Amount
of such outstanding Preferred Securities. See "Description of Preferred
Securities -- Voting Rights; Amendment of Trust Agreement." All guarantees and
agreements contained in the Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Company and shall inure to the
benefit of the holders of the Preferred Securities then outstanding.
    
 
   
EVENTS OF DEFAULT
    
 
   
     An event of default under the Guarantee will occur upon the failure of the
Company to perform any of its payment or other obligations thereunder. The
holders of not less than a majority in aggregate Liquidation Amount of the
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under the Guarantee.
    
 
   
     Any holder of Preferred Securities may institute a legal proceeding
directly against the Company to enforce its rights under the Guarantee without
first instituting a legal proceeding against IBC Capital, the Guarantee Trustee
or any other person or entity.
    
 
   
     The Company, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not the Company is in compliance with all
the conditions and covenants applicable to it under the Guarantee.
    
 
                                       70
<PAGE>   73
 
   
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
    
 
   
     The Guarantee Trustee, other than during the occurrence and continuance of
a default by the Company in performance of the Guarantee, undertakes to perform
only such duties as are specifically set forth in the Guarantee and, after
default with respect to any Guarantee, must exercise the same degree of care and
skill as a prudent person would exercise or use in the conduct of his or her own
affairs. Subject to this provision, the Guarantee Trustee is under no obligation
to exercise any of the powers vested in it by the Guarantee at the request of
any holder of any Preferred Securities unless it is offered reasonable indemnity
against the costs, expenses and liabilities that might be incurred thereby.
    
 
   
TERMINATION OF THE GUARANTEE
    
 
   
     The Guarantee will terminate and be of no further force and effect upon
full payment of the Redemption Price of the Preferred Securities, upon full
payment of the amounts payable upon liquidation of IBC Capital or upon
distribution of the Subordinated Debentures to the holders of the Preferred
Securities. The Guarantee will continue to be effective or will be reinstated,
as the case may be, if at any time any holder of the Preferred Securities must
restore payment of any sums paid under such Preferred Securities or the
Guarantee.
    
 
   
GOVERNING LAW
    
 
   
     The Guarantee will be governed by and construed in accordance with the laws
of the State of Michigan.
    
 
   
THE EXPENSE AGREEMENT
    
 
   
     Pursuant to the Expense Agreement entered into by the Company under the
Trust Agreement (the "Expense Agreement"), the Company will irrevocably and
unconditionally guarantee to each person or entity to whom IBC Capital becomes
indebted or liable, the full payment of any costs, expenses or liabilities of
IBC Capital, other than obligations of IBC Capital to pay to the holders of the
Preferred Securities or other similar interests in IBC Capital of the amounts
due such holders pursuant to the terms of the Preferred Securities or such other
similar interests, as the case may be.
    
 
   
                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
    
   
                          THE SUBORDINATED DEBENTURES
    
   
                               AND THE GUARANTEE
    
 
   
FULL AND UNCONDITIONAL GUARANTEE
    
 
   
     Payments of Distributions and other amounts due on the Preferred Securities
(to the extent IBC Capital has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Company as and to the extent
set forth under "Description of Guarantee." Taken together, the Company's
obligations under the Subordinated Debentures, the Indenture, the Trust
Agreement, the Expense Agreement, and the Guarantee provide, in the aggregate, a
full, irrevocable and unconditional guarantee of payment of distributions and
other amounts due on the Preferred Securities. No single document standing alone
or operating in conjunction with fewer than all of the other documents
constitutes such guarantee. It is only the combined operation of these documents
that has the effect of providing a full, irrevocable and unconditional guarantee
of IBC Capital's obligations under the Preferred Securities. If and to the
extent that the Company does not make payments on the Subordinated Debentures,
IBC Capital will not pay Distributions or other amounts due on the Preferred
Securities. The Guarantee does not cover payment of Distributions when IBC
Capital does not have sufficient funds to pay such Distributions. In such event,
the remedy of a holder of Preferred Securities is to institute a legal
proceeding directly against the Company for enforcement of payment of such
Distributions to such holder. The obligations of the Company under the Guarantee
are subordinate and junior in right of payment to all Senior Debt, Subordinated
Debt and, under certain circumstances, Additional Senior Obligations of the
Company.
    
 
                                       71
<PAGE>   74
 
   
SUFFICIENCY OF PAYMENTS
    
 
   
     As long as payments of interest and other payments are made when due on the
Subordinated Debentures, such payments will be sufficient to cover Distributions
and other payments due on the Preferred Securities, primarily because (i) the
aggregate principal amount of the Subordinated Debentures will be equal to the
sum of the aggregate stated Liquidation Amount of the Preferred Securities and
Common Securities; (ii) the interest rate and interest and other payment dates
on the Subordinated Debentures will match the Distribution rate and Distribution
and other payment dates for the Preferred Securities; (iii) the Company shall
pay for all and any costs, expenses and liabilities of IBC Capital except IBC
Capital's obligations to holders of the Preferred Securities; and (iv) the Trust
Agreement further provides that IBC Capital will not engage in any activity that
is not consistent with the limited purposes of IBC Capital.
    
 
   
     Notwithstanding anything to the contrary in the Indenture, the Company has
the right to set-off any payment it is otherwise required to make thereunder
with and to the extent the Company has theretofore made, or is concurrently on
the date of such payment making, a payment under the Guarantee.
    
 
   
ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES
    
 
   
     A holder of any Preferred Security may institute a legal proceeding
directly against the Company to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee, IBC Capital
or any other person or entity.
    
 
   
     A default or event of default under any Senior Debt, Subordinated Debt or
Additional Senior Obligations of the Company would not constitute a default or
Event of Default. However, in the event of payment defaults under, or
acceleration of, Senior Debt, Subordinated Debt or Additional Senior Obligations
of the Company, the subordination provisions of the Indenture provide that no
payments may be made in respect of the Subordinated Debentures until such Senior
Debt, Subordinated Debt or Additional Senior Obligations has been paid in full
or any payment default thereunder has been cured or waived. Failure to make
required payments on the Subordinated Debentures would constitute an Event of
Default.
    
 
   
LIMITED PURPOSE OF IBC CAPITAL
    
 
   
     The Preferred Securities evidence a beneficial interest in IBC Capital, and
IBC Capital exists for the sole purpose of issuing its Preferred Securities and
Common Securities and investing the proceeds thereof in Subordinated Debentures.
A principal difference between the rights of a holder of a Preferred Security
and a holder of a Subordinated Debenture is that a holder of a Subordinated
Debenture is entitled to receive from the Company the principal amount of and
interest accrued on Subordinated Debentures held, while a holder of Preferred
Securities is entitled to receive Distributions from IBC Capital (or from the
Company under the Guarantee) if and to the extent IBC Capital has funds
available for the payment of such Distributions.
    
 
   
RIGHTS UPON TERMINATION
    
 
   
     Upon any voluntary or involuntary termination, winding-up or liquidation of
IBC Capital involving the liquidation of the Subordinated Debentures, the
holders of the Preferred Securities will be entitled to receive, out of assets
held by IBC Capital, the Liquidation Distribution in cash. See "Description of
Preferred Securities -- Liquidation Distribution Upon Termination." Upon any
voluntary or involuntary liquidation or bankruptcy of the Company, the Property
Trustee, as holder of the Subordinated Debentures, would be a subordinated
creditor of the Company, subordinated in right of payment to all Senior Debt,
Subordinated Debt and Additional Senior Obligations as set forth in the
Indenture, but entitled to receive payment in full of principal and interest
before any stockholders of the Company receive payments or distributions. Since
the Company is the guarantor under the Guarantee and has agreed to pay for all
costs, expenses and liabilities of IBC Capital (other than IBC Capital's
obligations to the holders of its Preferred Securities), the positions of a
holder of the Preferred Securities and a holder of the Subordinated Debentures
relative to other creditors and to stockholders of the Company in the event of
liquidation or bankruptcy of the Company are expected to be substantially the
same.

<PAGE>   75
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The Company's authorized capital stock consists of 200,000 shares of
preferred stock, none of which are outstanding, and 14,000,000 shares of Common
Stock, 2,861,399 of which were outstanding as of September 30, 1996. The
following is a description of the Company's capital stock.
 
COMMON STOCK
 
     Subject to the rights, if any, of holders of any of the Company's preferred
stock then outstanding, all voting rights are vested in holders of shares of
Common Stock. Each share of Common Stock entitles the holder thereof to one
vote. Holders of shares of Common Stock are not entitled to cumulative voting
rights and have no preemptive right to subscribe for additional securities
issuable by the Company.
 
     Subject to any prior rights of holders of preferred stock then outstanding,
holders of the Company's Common Stock are entitled to receive dividends as the
Board of Directors may from time to time declare out of funds legally available
for that purpose. In the event of the liquidation, dissolution or winding up of
the Company, holders of Common Stock are entitled to share pro rata in the
assets available for distribution to holders of Common Stock. The outstanding
shares of Common Stock are fully paid and non-assessable. The Company's transfer
agent is State Street Bank & Trust Company.
 
PREFERRED STOCK
 
   
     The Board of Directors of the Company is authorized to issue shares of
preferred stock in series and affix the particular designations and terms of
those shares, including dividend rates, conversion prices, voting rights,
redemption prices and other matters, without further approval of the Company's
shareholders. No series of preferred stock is currently designated by the Board.
    
 
GENERAL
 
     The Company's Articles of Incorporation and the Michigan Business
Corporation Act contain provisions which could be utilized by the Company to
impede any efforts to acquire control of the Company, namely:
 
     Classified Board of Directors. The Company's Articles of Incorporation
provide for the division of the Board of Directors into three classes with
staggered three-year terms of office. Accordingly, because a person considering
the acquisition of voting control of the Company could not necessarily obtain
majority control of the Board of Directors until the second annual meeting of
the Company's shareholders following the acquisition of voting control, such a
person might be dissuaded from seeking to obtain voting control of the Company.
 
     Michigan Fair Price Provisions. Chapter 7A of the Michigan Business
Corporation Act impacts certain business combinations involving Michigan
corporations such as the Company. Except in cases in which certain minimum
price, form of consideration, and procedural requirements are satisfied or for
certain transactions that may be approved in advance by the Company's Board of
Directors, higher than normal voting requirements are imposed with respect to
various transactions involving persons who own ten percent or more of the
Company's voting stock (referred to as "Interested Shareholders"). Transactions
to which the higher voting requirements apply require an advisory statement from
the Board of Directors and must be approved by not less than 90% of the votes of
each class of stock entitled to vote and by not less than two-thirds of the
votes, other than the votes of Interested Shareholders who are (or whose
affiliates are) a party to the proposed transaction or an affiliate of the
Interested Shareholders, of each class entitled to vote.
 
     Michigan Shareholder Equity Provisions. Chapter 7B of the Michigan Business
Corporation Act affects the voting rights of persons who acquire more than 20%,
33 1/3%, or 50 percent of a Michigan corporation's voting stock (referred to as
"Control Shares"). Chapter 7B denies shareholder voting rights to those persons
or entities who make purchase offers or investors who increase their holdings
above any of the Control Share levels, unless they are granted voting rights by
a majority vote of all disinterested shareholders (shareholders excluding the
bidders or owners of Control Shares and the corporation's management). If the
shareholders do not elect to grant voting rights to Control Shares, under
certain circumstances, the Control Shares may become subject to redemption.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
    
 
   
GENERAL
    
 
   
     This section is a summary of the material United States federal income tax
considerations that may be relevant to the purchasers of Preferred Securities
and represents the opinion of Varnum, Riddering, Schmidt & Howlett LLP, counsel
to the Company and IBC Capital, insofar as it relates to matters of law and
legal conclusions. The conclusions expressed herein are based upon current
provisions of the Internal Revenue Code of 1986, as amended ("Code"),
regulations thereunder and current administrative rulings and court decisions,
all of which are subject to change at any time, with possible retroactive
effects. Subsequent changes may cause tax consequences to vary substantially
from the consequences described below. Furthermore, the authorities on which
this summary is based are subject to various interpretations, and it is
therefore possible that the federal income tax treatment of the purchase,
ownership, and disposition of Preferred Securities may differ from the treatment
described below.
    
 
   
     No attempt has been made in the following discussion to comment on all
United States federal income tax matters affecting purchasers of Preferred
Securities. Moreover, the discussion generally focuses on holders of Preferred
Securities who are individual citizens or residents of the United States and who
acquire Preferred Securities on their original issue at their offering price and
hold Preferred Securities as capital assets. The discussion has only limited
application to dealers in securities, corporations, estates, trusts or
nonresident aliens and does not address all the tax consequences that may be
relevant to holders who may be subject to special tax treatment, such as, for
example, banks, thrifts, real estate investment trusts, regulated investment
companies, insurance companies, dealers in securities or currencies, tax-exempt
investors, or persons that will hold the Preferred Securities as a position in a
"straddle," as part of a "synthetic security" or "hedge," as part of a
"conversion transaction" or other integrated investment, or as other than a
capital asset. This summary also does not address the tax consequences to
persons that have a functional currency other than the U.S. dollar or the tax
consequences to shareholders, partners or beneficiaries of a holder of Preferred
Securities. Further, it does not include any description of any alternative
minimum tax consequences or the tax laws of any state or local government or of
any foreign government that may be applicable to the Preferred Securities.
Accordingly, each prospective investor should consult, and should rely
exclusively on, the investor's own tax advisors in analyzing the federal, state,
local and foreign tax consequences of the purchase, ownership or disposition of
Preferred Securities.
    
 
   
CLASSIFICATION OF THE SUBORDINATED DEBENTURES
    
 
   
     The Company intends to take the position that the Subordinated Debentures
will be classified for United States federal income tax purposes as indebtedness
of the Company under current law, and, by acceptance of a Preferred Security,
each holder covenants to treat the Subordinated Debentures as indebtedness and
the Preferred Securities as evidence of an indirect beneficial ownership
interest in the Subordinated Debentures. No assurance can be given, however,
that such position of the Company will not be challenged by the Internal Revenue
Service or, if challenged, that such a challenge will not be successful. The
remainder of this discussion assumes that the Subordinated Debentures will be
classified for United States federal income tax purposes as indebtedness of the
Company.
    
 
   
CLASSIFICATION OF IBC CAPITAL
    
 
   
     With respect to the Preferred Securities, Varnum, Riddering, Schmidt &
Howlett LLP, counsel to the Company and IBC Capital, has rendered its opinion
generally to the effect that, under then current law and assuming full
compliance with the terms of the Trust Agreement and Indenture, IBC Capital will
be classified for United States federal income tax purposes as a grantor trust
and not as an association taxable as a corporation. Accordingly, for United
States federal income tax purposes, each holder of Preferred Securities
generally will be treated as owning an undivided beneficial interest in the
Subordinated Debentures, and each holder will be required to include in its
gross income any original issue discount ("OID") accrued with respect to its
allocable share of the Subordinated Debentures whether or not cash is actually
distributed to such holder.
    
 
                                       74
<PAGE>   77
 
   
POTENTIAL EXTENSION OF INTEREST PAYMENT PERIOD AND ORIGINAL ISSUE DISCOUNT
    
 
   
     Because the Company has the option, under the terms of the Subordinated
Debentures, to defer payments of interest by extending interest payment periods
for up to 20 consecutive quarters, all of the stated interest payments on the
Subordinated Debentures will be treated as OID. Holders of debt instruments
issued with OID must include that discount in income on an economic accrual
basis before the receipt of cash attributable to the interest, regardless of
their method of tax accounting. Generally, all of a holder's taxable interest
income with respect to the Subordinated Debentures will be accounted for as OID.
Actual payments and distributions of stated interest will not, however, be
separately reported as taxable income. The amount of OID that accrues in any
quarter will approximately equal the amount of the interest that accrues on the
Subordinated Debentures in that quarter at the stated interest rate. In the
event that the interest payment period is extended, holders will continue to
accrue OID approximately equal to the amount of the interest payment due at the
end of the extended interest payment period on an economic accrual basis over
the length of the extended interest payment period.
    
 
   
     Because income on the Preferred Securities will constitute OID, corporate
holders of Preferred Securities will not be entitled to a dividends-received
deduction with respect to any income recognized with respect to the Preferred
Securities.
    
 
   
MARKET DISCOUNT AND ACQUISITION PREMIUM
    
 
   
     Holders of Preferred Securities other than a holder who purchased the
Preferred Securities upon original issuance may be considered to have acquired
their undivided interests in the Subordinated Debentures with "market discount"
or "acquisition premium" as such phrases are defined for United States federal
income tax purposes. Such holders are advised to consult their tax advisors as
to the income tax consequences of the acquisition, ownership and disposition of
the Preferred Securities.
    
 
   
RECEIPT OF SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF IBC CAPITAL
    
 
   
     Under certain circumstances, as described under "Description of the
Preferred Securities -- Redemption or Exchange," the Subordinated Debentures may
be distributed to holders of Preferred Securities upon a liquidation of IBC
Capital. Under current United States federal income tax law, such a distribution
would be treated as a nontaxable exchange to each such holder and would result
in such holder having an aggregate tax basis in the Subordinated Debentures
received in the liquidation equal to such holder's aggregate tax basis in the
Preferred Securities immediately before the distribution. A holder's holding
period in the Subordinated Debentures so received in liquidation of IBC Capital
would include the period for which such holder held the Preferred Securities.
    
 
   
     If, however, a Tax Event occurs which results in IBC Capital being treated
as an association taxable as a corporation, the distribution would likely
constitute a taxable event to holders of the Preferred Securities. Under certain
circumstances described herein, the Subordinated Debentures may be redeemed for
cash and the proceeds of such redemption distributed to holders in redemption of
their Preferred Securities. Under current law, such a redemption would, for
United States federal income tax purposes, constitute a taxable disposition of
the redeemed Preferred Securities, and a holder would recognize gain or loss as
if the holder sold such Preferred Securities for cash. See "Description of
Preferred Securities -- Redemption or Exchange."
    
 
   
DISPOSITION OF PREFERRED SECURITIES
    
 
   
     A holder that sells Preferred Securities will recognize gain or loss equal
to the difference between the amount realized on the sale of the Preferred
Securities and the holder's adjusted tax basis in such Preferred Securities. A
holder's adjusted tax basis in the Preferred Securities generally will be its
initial purchase price increased by OID previously includible in such holder's
gross income to the date of disposition and decreased by payments received on
the Preferred Securities to the date of disposition. Such gain or loss will be a
capital gain or loss and will be a long-term capital gain or loss if the
Preferred Securities have been held for more than one year at the time of sale.
    
 
                                       75
<PAGE>   78
 
   
     The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Debentures. A holder that disposes of its Preferred Securities
between record dates for payments of distributions thereon will be required to
include accrued but unpaid interest on the Subordinated Debentures through the
date of disposition in income as ordinary income, and to add such amount to its
adjusted tax basis in its pro rata share of the underlying Subordinated
Debentures deemed disposed of. To the extent the selling price is less than the
holder's adjusted tax basis (which basis will include, in the form of OID, all
accrued but unpaid interest), a holder will recognize a capital loss. Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.
    
 
   
EFFECT OF PROPOSED CHANGES IN TAX LAWS
    
 
   
     The Clinton Administration has proposed statutory changes in the Federal
income tax rules relating to financial instruments. Under one such proposal,
debt with a maximum maturity of more than 20 years that is not shown as debt on
the applicable balance sheet of the issuer would be characterized as equity of
the issuer, with the result that interest would be nondeductible to the issuer.
If this proposal were enacted and applied to the Preferred Securities, a Tax
Event would occur.
    
 
   
     The Company has been advised by counsel that, under certain transition
rules contained in the proposed legislation, the Preferred Securities would not
be subject to such legislation. Moreover, the Chairman of the House Ways and
Means Committee and the Senate Finance Committee, as well as the ranking
minority members of the House Ways and Means Committee, have publicly indicated
that the proposals, if enacted, would not apply prior to the date of
"appropriate Congressional action." Thus, the Company believes such proposed
legislation, if ultimately enacted, will not apply to the Preferred Securities.
Nevertheless, no assurance can be given in this regard.
    
 
   
BACKUP WITHHOLDING AND INFORMATION REPORTING
    
 
   
     The amount of OID accrued on the Preferred Securities held of record by
individual citizens or residents of the United States, or certain trusts,
estates, and partnerships, will be reported to the Internal Revenue Service on
Forms 1099, which forms should be mailed to such holders of Preferred Securities
by January 31 following each calendar year. Payments made on, and proceeds from
the sale of, the Preferred Securities may be subject to a "backup" withholding
tax (currently at 31%) unless the holder complies with certain identification
and other requirements. Any amounts withheld under the backup withholding rules
will be allowed as a credit against the holder's United States federal income
tax liability, provided the required information is provided to the Internal
Revenue Service.
    
 
   
     THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON THE
PARTICULAR SITUATION OF A HOLDER OF PREFERRED SECURITIES. HOLDERS OF PREFERRED
SECURITIES SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE PREFERRED
SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER
TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER
TAX LAWS.

                              ERISA CONSIDERATIONS
    
 
   
     Generally, employee benefit plans that are subject to the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or Section 4975 of
the Code ("Plans"), may purchase Preferred Securities, subject to the investing
fiduciary's determination that the investment in Preferred Securities satisfies
ERISA's fiduciary standards and other requirements applicable to investments by
the Plan.
    
 
   
     In any case, the Company and/or any of its affiliates may be considered a
"party in interest" (within the meaning of ERISA) or a "disqualified person"
(within the meaning of Section 4975 of the Code) with respect to certain plans
(generally, Plans maintained or sponsored by, or contributed to by, any such
persons). The acquisition and ownership of Preferred Securities by a Plan (or by
an individual retirement arrangement or other Plans described in Section
4975(e)(1) of the Code) with respect to which the Company or any of its
affiliates is considered a party in interest or a disqualified person, may
constitute or result in a prohibited transaction under ERISA or Section 4975 of
the Code, unless such Preferred Securities are acquired pursuant to and in
accordance with an applicable exemption.
    
 
   
     As a result, Plans with respect to which the Company or any of its
affiliates is a party in interest or a disqualified person should not acquire
Preferred Securities unless such Preferred Securities are acquired pursuant to
and in accordance with an applicable exemption. Any other Plans or other
entities whose assets include Plan assets subject to ERISA or Section 4975 of
the Code proposing to acquire Preferred Securities should consult with their own
counsel.

                                  UNDERWRITING
 
   
     Subject to the terms and conditions set forth in the Underwriting
Agreement, the form of which is filed as an exhibit to the Registration
Statement of which this Prospectus is a part, the Company and IBC Capital have
agreed that IBC Capital will sell to Stifel, Nicolaus & Company, Incorporated
("Underwriter") and the Underwriter has agreed to purchase from IBC Capital
600,000 Preferred Securities. The Underwriter proposes initially to offer the
Preferred Securities to the public at the initial offering price set forth on
the cover page of this Prospectus and to certain dealers at such price less a
concession not in excess of $       per Preferred Security. The Underwriters may
allow, and such dealers may reallow, a discount not in excess of $       per
Preferred Security to certain other dealers. After the initial offering, the
offering price and other selling terms may be changed by the Underwriter.
    
 
   
     IBC Capital has granted an option to the Underwriter, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to 90,000
additional Preferred Securities to cover over-allotments, if any, at the same
price per Preferred Security as the initial 600,000 Preferred Securities to be
purchased by the Underwriter. The Underwriter may purchase such Preferred
Securities only to cover over-allotments made in connection with the offering.
    
 
   
     In view of the fact that the proceeds from the sale of Preferred Securities
will be used to purchase the Subordinated Debentures issued by the Company, the
Underwriting Agreement provides that the Company will pay as Underwriter's
Compensation for the Underwriter's services an amount of $       per Preferred
Security.
    
 
   
     The Company and IBC Capital have agreed that, during the period beginning
from the date of the Underwriting Agreement and continuing to and including the
earlier of (i) the termination of trading restrictions on the Preferred
Securities, as determined by the Underwriter, or (ii)   days after the closing
date, they will not, directly or indirectly, offer, sell, agree to sell or
otherwise dispose of any Preferred Securities, any other beneficial interests in
the assets of IBC Capital, or any other securities of IBC Capital or the Company
which are substantially similar to the Preferred Securities, including any
guarantee of such beneficial interests or substantially similar securities, or
any securities convertible into or exchangeable for or representing the right to
receive securities, preferred securities or any such substantially similar
securities of either IBC Capital or the Company, without the prior written
consent of the Underwriter, except for the Preferred Securities offered in
connection with the offering.
    
 
   
     The Underwriting Agreement provides that the Company and IBC Capital will
indemnify the Underwriter against certain liabilities, including civil
liabilities under the Securities Act of 1933, as amended, or will contribute to
payments the Underwriter may be required to make in respect thereof.
    
 
                             VALIDITY OF SECURITIES
 
   
     Certain matters of Delaware law relating to the validity of the Preferred
Securities, the enforceability of the Trust Agreement and the formation of IBC
Capital will be passed upon by Richards, Layton & Finger, special Delaware
counsel to the Company and IBC Capital. Certain legal matters for the Company
and IBC Capital, including the validity of the Guarantee and the Subordinated
Debentures will be passed upon for the Company and IBC Capital by Varnum,
Riddering, Schmidt & Howlett LLP, Grand Rapids, Michigan, counsel to the Company
and IBC Capital. Certain legal matters will be passed upon for the Underwriter
by Bryan Cave LLP, St. Louis, Missouri. Varnum Riddering, Schmidt & Howlett LLP
and Bryan Cave LLP, will rely on the opinion of Richards, Layton & Finger as to
matters of Delaware law. Certain matters relating to United States federal
income tax considerations will be passed upon for the Company by Varnum,
Riddering, Schmidt & Howlett LLP.

     The Company is subject to the information requirements of the Securities
Exchange Act of 1934, as amended ("Exchange Act"), and, in accordance therewith
files reports, proxy statements and other information with the Securities and
Exchange Commission (the "Commission"). The reports, proxy statements and other

Commission Room 1024, 450 Fifth Street, N.W., Washington, D.C. 20549, and at the
Commission's Regional Offices located at 7 World Trade Center, Suite 1300, New
York, New York 10048, and 500 West Madison Street, Suite 1400, Chicago, Illinois
60601. Copies of such materials can be obtained by mail from the Public
Reference Section of the Commission at 450 Fifth Street, N.W., Washington, D.C.

statements and other information regarding registrants that file electronically
with the Commission.
    
 
   
     No separate financial statements of IBC Capital have been included herein.
The Company and IBC Capital do not consider that such financial statements would
be material to holders of Preferred Securities because IBC Capital is a newly

operations and is not engaged in and does not propose to engage in any activity
other than holding as trust assets the Subordinated Debentures of the Company
and issuing the Trust Securities. See "Description of Preferred Securities,"
"Description of Subordinated Debentures" and "Description of Guarantee." In
addition, the Company and IBC Capital do not expect that IBC Capital will be
filing reports under the Exchange Act with the Commission.
    
 
     The Company has filed with the Commission a Registration Statement on Form
S-2 (herein, together with all amendments and exhibits thereto and documents
incorporated by reference, referred to as the "Registration Statement") under
the Securities Act of 1933, as amended (the "Securities Act"). This Prospectus

                          INDEPENDENT BANK CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies and practices of Independent Bank
Corporation and subsidiaries conform with generally accepted accounting
principles and prevailing practices within the banking industry. The following
summaries describe the significant accounting and reporting policies that are
employed in the preparation of the consolidated financial statements.
 
     The Banks transact business in the single industry segment of commercial
banking. The Banks' activities cover traditional phases of commercial banking,
including checking and savings accounts, commercial and agricultural lending,
direct and indirect consumer financing, mortgage lending and deposit box
services. The principal markets are the rural and suburban communities across
lower Michigan that are served by the Banks' branch networks. Subject to
established underwriting criteria, the Banks may also participate in commercial
lending transactions with certain non-affiliated banks and purchase real estate
mortgage loans from third-party originators. The local economies of the
communities served by the Banks are relatively stable and reasonably
diversified.
 
     Management is required to make estimates and assumptions in the preparation
of the financial statements which affect the amounts reported. Material
estimates that are particularly susceptible to changes in the near-term relate
to the determination of the allowance for loan losses. While Management uses
relevant information to recognize losses on loans, future provisions for related
losses may be necessary based on changes in economic conditions and customer
circumstances.
 
     Principles of Consolidation -- The consolidated financial statements
include the accounts of Independent Bank Corporation and its subsidiaries. The
income, expenses, assets and liabilities of the subsidiaries are included in the
respective accounts of the consolidated financial statements, after elimination
of all material intercompany accounts and transactions.
 
     Statements of Cash Flows -- For purposes of reporting cash flows, cash and
cash equivalents include cash on hand, amounts due from banks, and federal funds
sold. Generally, federal funds are sold for one-day periods. The Company reports
net cash flows for customer loan and deposit transactions.
 
     Loans Held for Sale -- Loans designated as held for sale are carried at the
lower of aggregate amortized cost or market value. Lower of cost or market value
adjustments, as well as realized gains and losses, are recorded in current
earnings. The Company will adopt Statement of Financial Accounting Standards No.
122, "Accounting for Mortgage Servicing Rights," ("SFAS #122") on January 1,
1996. SFAS #122 will require the Banks to prospectively recognize rights to
service mortgage loans as separate assets. This statement will also require the
Banks to assess these mortgage servicing rights for impairment based on the fair
value of those rights. The adoption of SFAS #122 on a prospective basis in the
first quarter of 1996 is not expected to have a significant effect on the
consolidated financial statements.
 
     Securities -- The Company adopted Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities," ("SFAS #115") effective January 1, 1994. Under SFAS #115, the
Company is required to classify its securities as trading, held to maturity or
available for sale.
 
     Trading securities are bought and held principally for the purpose of
selling them in the near-term and are reported at fair value with realized and
unrealized gains and losses included in earnings. The Company does not have any
trading securities. Securities classified as held to maturity represent those
securities for which the Banks have the positive intent and ability to hold
until maturity and are reported at cost, adjusted for amortization of premiums
and accretion of discounts computed on the level yield method. Securities
available for sale represent those securities not classified as trading or held
to maturity and are reported at fair value with unrealized gains and losses, net
of applicable income taxes reported as a separate component of shareholders'
equity. Gains and losses realized on the sale of securities available for sale
are determined using

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED
the specific identification method and are recognized on a trade-date basis.
Premiums and discounts are recognized in interest income computed on the level
yield method.
 
     The Company adopted Statement of Financial Accounting Standards No. 119,
"Disclosure About Derivative Financial Instruments and Fair Value of Financial
Instruments," ("SFAS #119") effective December 31, 1994. SFAS #119 requires
disclosure about off-balance sheet financial instruments.
 
     Loan Revenue Recognition -- Interest on loans is accrued based on the
principal amounts outstanding. The accrual of interest income is discontinued
when a loan becomes 90 days past due and the borrower's capacity to repay the
loan and collateral values appear insufficient. A non-accrual loan may be
restored to accrual status when interest and principal payments are current and
the loan appears otherwise collectible.
 
     Certain loan fees, net of direct loan origination costs, are deferred and
recognized as an adjustment of yield over the life of the related loan. Fees
received in connection with loan commitments are deferred until the loan is
advanced and are then recognized over the life of the loan as an adjustment of
yield. Fees on commitments that expire unused are recognized at expiration. Fees
received for a letter of credit are recognized as fee revenue over its life.
 
     Allowance for Loan Losses -- Some loans may not be repaid in full.
Therefore, an allowance for loan losses is maintained at a level which
management has determined to be adequate to absorb inherent losses. Management's
assessment of the allowance is based on prior years' loss experience, general
economic conditions and trends, as well as the review of specific loans.
Increases in the allowance are recorded by a provision for loan losses charged
to expense and, although management periodically allocates portions of the
allowance to specific loans and loan portfolios, the entire allowance is
available for any charge-offs which occur. Collection efforts may continue and
future recoveries may occur after a loan is charged-off.
 
     The Company has adopted Statement of Financial Accounting Standards No.
114, "Accounting by Creditors for Impairment of a Loan," ("SFAS #114"). SFAS
#114, which has been subsequently amended by SFAS #118, requires the Company to
measure its investment in certain impaired loans based on one of three methods:
the loan's observable market price, the fair value of the collateral or the
present value of expected future cash flows discounted at the loan's effective
interest rate. The adoption of this Statement in 1995 did not have a significant
effect on the allowance for loan losses.
 
     Property and Equipment -- Property and equipment is stated at cost less
accumulated depreciation and amortization. Depreciation and amortization is
computed using both straight-line and accelerated methods over the estimated
useful lives of the related assets.
 
     Other Real Estate -- Other real estate represents properties acquired
through foreclosure or by acceptance of a deed in lieu of foreclosure. Prior to
1995, loan collateral which had been in-substance foreclosed was included in
other real estate. A portion of these properties has been sold on land contract
or financed at below market terms. The carrying values of these properties are
periodically evaluated and are adjusted to the lower of cost or fair value minus
estimated costs to sell. Other real estate and repossessed assets totaling
$760,000 and $1,381,000 at December 31, 1995 and 1994, respectively, are
included in other assets.
 
     Intangible Assets -- Goodwill, which represents the excess of the purchase
price over the fair value of net tangible assets acquired, is amortized on a
straight-line basis over the period of expected benefit, generally 12 to 20
years. Goodwill totaled $1,099,000 and $1,188,000 as of December 31, 1995 and
1994, respectively. Other intangible assets are amortized using both
straight-line and accelerated methods over 12 to 15 years. Other intangibles
amounted to $1,407,000 and $1,096,000 as of December 31, 1995 and 1994,
respectively.

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED
     Income Taxes -- Effective January 1, 1993, the Company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes," ("SFAS
#109") with no material impact on the financial statements. SFAS #109 required
that the Company employ the asset and liability method of accounting for income
taxes. The objective of this method is to establish deferred tax assets and
liabilities for the temporary differences between the financial reporting basis
and the tax basis of the Company's assets and liabilities at enacted tax rates
expected to be in effect when such amounts are realized or settled. Under the
asset and liability method, the effect of a change in tax rates is recognized in
income in the period that includes the enactment date. The deferred tax asset is
subject to a valuation allowance for that portion of the asset for which it is
more likely than not that it will not be realized.
 
     The Company and its subsidiaries file a consolidated federal income tax
return. Intercompany tax liabilities are settled as if each subsidiary filed a
separate return.
 
     Common Stock -- At December 31, 1995, 46,387 shares of common stock were
reserved for issuance under the Incentive Share Grant Plan, 26,089 shares of
common stock were reserved for issuance under the dividend reinvestment plan and
128,275 shares of common stock were reserved for issuance under stock option
plans.
 
     Earnings Per Share -- Earnings per share is based on 2,861,898 average
shares and equivalents outstanding in 1995, 2,890,368 in 1994 and 2,878,386 in
1993. Per share data has been adjusted to give retroactive effect to 5% stock
dividends in 1996 and 1995.
 
     Retirement Plans -- The Company maintains an employee stock ownership plan
as well as a 401(k) plan for substantially all full-time employees.
 
     Reclassification -- Certain amounts in the 1994 and 1993 financial
statements have been reclassified to conform with the 1995 presentation.
 
NOTE 2 -- ACQUISITIONS
 
     On March 7, 1994, KSB Financial, Inc., ("KSB") merged with the Company. As
a result, The Kingston State Bank became a subsidiary of the Company. The
Company issued 225,649 shares of common stock in exchange for all of the
outstanding common stock of KSB. The merger was accounted for as a pooling of
interests and, accordingly, the accompanying financial statements were restated
to include the accounts and operations of KSB for all periods prior to the
merger.

NOTE 3 -- PENDING ACQUISITION
 
   
     On February 2, 1996, the Company entered into a definitive agreement to
merge with North Bank Corporation ("NBC"). As a result, North Bank will become a
subsidiary of the Company. Cash consideration is anticipated to approximate
$16,300,000. At December 31, 1995, NBC had total assets and loans of
$153,600,000 and $91,200,000 (unaudited), respectively. The transaction is
subject to approval by NBC shareholders and the Federal Reserve and will be
accounted for as a purchase. Accordingly, the assets acquired and the
liabilities assumed will be recorded at fair value. Goodwill is anticipated to
approximate $6,000,000.
    
 
NOTE 4 -- RESTRICTIONS ON CASH AND DUE FROM BANKS
 
     The Banks' legal reserve requirements were satisfied by maintaining
non-interest earning vault cash balances of $2,661,000 in 1995 and $2,547,000 in
1994. The Banks do not maintain compensating balances with correspondent banks.

     During November 1995, the Financial Accounting Standards Board issued a
"Guide to Implementation of Statement #115 on Accounting for Certain Investment
in Debt and Equity Securities." This guide allowed for a one-time change in the
classification of securities pursuant to SFAS #115 as of the date of the
implementation guide, but no later than December 31, 1995. As a result, the
Banks made a transfer of $52,601,000 to securities available for sale.

     Loans are presented net of deferred income of $1,434,000 at December 31,
1995, and $1,325,000 at December 31, 1994.
 
     Loans on non-accrual status, 90 days or more past due and still accruing
interest, or restructured amounted to $2,560,000, $2,834,000 and $3,213,000 at
December 31, 1995, 1994 and 1993, respectively. If these loans had continued to
accrue interest in accordance with their original terms, approximately $263,000,
$259,000, and $261,000 of interest income would have been realized in 1995, 1994
and 1993, respectively. Interest income accrued on these loans was approximately
$64,000, $102,000 and $143,000 in 1995, 1994 and 1993, respectively.
 
     Impaired loans totaled approximately $3,200,000 at December 31, 1995. In
addition to certain non-performing loans, other than homogeneous residential
mortgage and installment loans, impaired loans include commercial and
agricultural loans totaling $1,800,000 that have been separately identified as
impaired. The Banks' average investment in impaired loans approximated
$2,300,000 in 1995. Cash receipts on impaired loans on non-accrual status are
generally applied to the principal balance. Interest income recognized on
impaired loans in 1995 was approximately $70,000. Certain impaired loans with a
balance of approximately $700,000 had specific allocations of the allowance for
loan losses calculated in accordance with SFAS #114 totaling approximately
$250,000 at December 31, 1995. As a result of the implementation of SFAS #114,
certain loans that had previously been identified as in-substance foreclosed and
classified as other real estate have been transferred to loans at December 31,
1995.
 
     At December 31, 1995, 1994 and 1993, the Banks serviced loans totaling
approximately $124,000,000, $103,500,000 and $78,000,000, respectively, for the
benefit of third parties.

     The Company's aggregate income subject to federal income tax for the three
years ended December 31, 1995, totaled approximately $25,600,000. Consequently,
Management believes that at December 31, 1995, it is more likely than not that
the benefit of the gross deferred tax assets of $2,745,000 will be realized and
no valuation allowance is deemed necessary as of December 31, 1995.
 
NOTE 11 -- EMPLOYEE BENEFIT PLANS

option plans for certain employees of the Company and the Banks and for
non-employee directors of the Company. An aggregate of 137,800 shares of common
stock has been authorized for issuance under the plans. Options granted under
these plans are exercisable not earlier than one year after the date of grant,
at a price equal to the fair market value of the common stock on the date of
grant, and expire five years after the date of grant.

     The Company has a 401(k) and an employee stock ownership plan covering
substantially all full-time employees of the Company and the Banks. The Company
matches employee contributions to the 401(k) up to a maximum of 3% of
participating employees' eligible wages. Contributions to the employee stock
ownership plan are determined annually and require approval of the Company's
Board of Directors. For the years ended December 31, 1995, 1994 and 1993,
$704,000, $365,000 and $452,000 respectively, was expensed for these retirement
plans.
 
     Officers of the Company and the Banks participate in various
performance-based compensation plans. The 1988 Incentive Share Grant Plan
provides that the Board of Directors, at its sole discretion, may award
restricted shares of common stock to the participants in the Management
Incentive Compensation Plan in lieu of cash bonuses. The market value of such
incentive shares at the date of grant must equal twice the amount of the cash
incentive otherwise payable. Shares of common stock issued pursuant to the
Incentive Share Grant Plan vest over four years. For the years ended December
31, 1995, 1994 and 1993, amounts expensed for all incentive plans totaled
$876,000, $633,000, and $784,000, respectively.
 
     The Company also provides certain health care and life insurance programs
to substantially all full-time employees. These insurance programs are available
to retired employees at their expense.
 
     Effective January 1, 1996, the Company will adopt Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation", ("SFAS
#123"). SFAS #123 encourages companies to adopt a fair value method of
accounting for stock compensation plans. Those companies not adopting a fair
value method will be required to make pro-forma disclosures of net income and
earnings per share as if they had adopted the fair value accounting method.
Management anticipates the Company will elect the pro-forma disclosure method.
 
NOTE 12 -- FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
 
     In the normal course of business, the Banks enter into financial
instruments with off-balance sheet risk to meet the financing needs of customers
or to reduce exposure to fluctuations in interest rates. These financial
instruments may include commitments to extend credit, standby letters of credit
and interest rate swaps. There were no interest rate swaps in 1995, 1994 and
1993. Financial instruments involve varying degrees of credit and interest rate
risk in excess of amounts reflected in the consolidated balance sheets. Exposure

credit risk in the event of non-performance by the counterparties to the
financial instruments for loan commitments to extend credit and letters of

Management does not, however, anticipate material losses as a result of these
financial instruments.

  Standby letters of credit........................................     2,427,000      2,858,000
</TABLE>
 
     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and generally require payment of a fee. Since many of the commitments are
expected to expire without being drawn upon, the commitment amounts do not
represent future cash requirements. Commitments are issued subject to similar
underwriting standards, including collateral requirements, as are generally
involved in the extension of credit facilities.
 
     Standby letters of credit are written conditional commitments issued by the
Banks to guarantee the performance of a customer to a third party, primarily
public and private borrowing arrangements. Standby letters of credit generally
extend for periods of less than one year. The credit risk involved in such
transactions is essentially the same as that involved in extending loan
facilities and, accordingly, standby letters of credit are issued subject to
similar underwriting standards, including collateral requirements, as are
generally involved in the extension of credit facilities.

NOTE 15 -- UNDISTRIBUTED INCOME AND DIVIDEND LIMITATIONS OF SUBSIDIARIES
 
     Capital guidelines adopted by Federal and State regulatory agencies and
restrictions imposed by law limit the amount of cash dividends the Banks can pay
to the Company. At December 31, 1995, using the most restrictive of these
conditions for each Bank, the aggregate cash dividends that the Banks can pay
the Company without prior approval is approximately $18,930,000. It is not the
intent of Management to have dividends paid in amounts which would reduce the
capital of the Banks to levels below those which are considered prudent by
management and in accordance with guidelines of regulatory authorities.
 
NOTE 16 -- FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Financial Instruments" requires that the Company disclose
estimated fair values for its financial instruments. Many of the Company's
financial instruments lack an available trading market. Further, it is the
Company's general practice and intent to hold the majority of its financial
instruments to maturity. Significant estimates and assumptions were used to
determine the fair value of financial instruments. These estimates are
subjective in nature, involving uncertainties and matters of judgment, and
therefore, fair values cannot be determined with precision. Changes in
assumptions could significantly affect the estimates.
 
     Estimated fair values have been determined using available data and an
estimation methodology that is considered suitable for each category of
financial instrument. For assets and liabilities with floating interest rates
which reprice frequently and without significant credit risk, it is presumed
that estimated fair values approximate the recorded book balances.
 
     Financial instrument assets actively traded in a secondary market, such as
securities, have been valued using quoted market prices while recorded book
balances have been used for cash and due from banks and federal funds sold.
 
     The fair value of loans is calculated by discounting estimated future cash
flows using estimated market discount rates that reflect credit and interest
rate risk inherent in the loan.
 
     Financial instruments with stated maturities, such as certificates of
deposit, have been valued based on the discounted value of contractual cash
flows using a discount rate approximating current market rates for liabilities
with similar remaining maturities.
 
     Financial instrument liabilities with no stated maturities, such as demand
deposits, savings, NOW and money market accounts, have a fair value equal to the
amount payable on demand.

     The fair values for commitments to extend credit and standby letters of
credit are estimated to approximate their aggregate book balance.
 
     Fair value estimates are made at a specific point in time, based on
relevant market information and information about the financial instrument.
These estimates do not reflect any premium or discount that could result from
offering for sale the entire holdings of a particular financial instrument.
 
     Fair value estimates are based on existing on and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business, the value of future earnings attributable to off-balance sheet
activities and the value of assets and liabilities that are not considered
financial instruments.
 
     Fair value estimates for deposit accounts do not include the value of the
substantial core deposit intangible asset resulting from the low-cost funding
provided by the deposit liabilities compared to the cost of borrowing funds in
the market.

                          INDEPENDENT AUDITOR'S REPORT
 
BOARD OF DIRECTORS AND SHAREHOLDERS
INDEPENDENT BANK CORPORATION
IONIA, MICHIGAN
 
     We have audited the accompanying consolidated statements of financial
condition of Independent Bank Corporation and subsidiaries as of December 31,
1995 and 1994, and the related consolidated statements of operations,
shareholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1995. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express our
opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Independent
Bank Corporation and subsidiaries as of December 31, 1995 and 1994, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1995, in conformity with generally accepted
accounting principles.
 
     As discussed in note 1 to the consolidated financial statements, the
Company changed its method of accounting for income taxes in 1993 to adopt the
provisions of Financial Accounting Standards Board's Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." As discussed
in note 1, the Company changed its method of accounting for investments to adopt
the provisions of Financial Accounting Standards Board's SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" at January 1,
1994. As discussed in note 1, the Company changed its method of accounting for
impaired loans in 1995 to adopt the provisions of Financial Accounting Standards
Board's SFAS No. 114, "Accounting by Creditors for Impairment of a Loan", as
amended by SFAS No. 118, "Accounting by Creditors for Impairment of a Loan --
Income Recognition and Disclosures."

               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
     1. In the opinion of management of the Company, the accompanying unaudited
consolidated financial statements contain all the adjustments (consisting only
of normal recurring accruals) necessary to present fairly the consolidated
financial condition of the Company as of September 30, 1996 and the results of
operations for the nine-month periods ended September 30, 1996 and 1995.
 
     2. Management's assessment of the allowance for loan losses is based on an
evaluation of the loan portfolio, recent loss experience, current economic
conditions and other pertinent factors. Loans on non-accrual status, past due
more than 90 days, or restructured amounted to $3,451,000 at September 30, 1996.
(See Management's Discussion and Analysis of Financial Condition and Results of
Operations).
 
     3. The provision for income taxes represents federal income tax expense
calculated using annualized rates on taxable income generated during the
respective periods.
 
     4. The unaudited pro forma combined results for the Company and NBC set
forth below are presented as if the NBC Acquisition had occurred at the
beginning of the periods presented.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS
NORTH BANK CORPORATION
HALE, MICHIGAN
 
     We have audited the accompanying consolidated balance sheets of North Bank
Corporation as of December 31, 1995 and 1994, and the related consolidated
statements of income, changes in shareholders' equity and cash flows for each of
the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of North Bank
Corporation as of December 31, 1995 and 1994, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1995, in conformity with generally accepted accounting principles.
 
     As discussed in Note 2 to the consolidated financial statements, the
Corporation changed its methods of accounting for impaired loans in 1995 and
investment securities and income taxes in 1993 to conform to new accounting
standards. The change in accounting for income taxes was made retroactively to
January 1, 1991.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994
 
NOTE 1 -- NATURE OF OPERATIONS
 
     The consolidated financial statements include the accounts of North Bank
Corporation and its wholly-owned subsidiary, North Bank (the Bank), and the
Bank's wholly-owned subsidiary, First Central Mortgage Corporation, after
elimination of significant inter-company transactions and accounts.
 
     On October 3, 1994, North Bank acquired First Central Mortgage Corporation,
a residential mortgage originating company headquartered in Saginaw, Michigan.
The acquisition was recorded under the purchase method. Intangible assets
acquired are being amortized over their estimated economic lives.
 
     In October 1995, North Bank acquired a branch of First of America in
Hubbard Lake, Michigan. Deposits acquired were approximately $6.8 million.
Intangible assets associated with this acquisition are being amortized over
their estimated economic lives.
 
     The Bank grants commercial, installment and residential loans to customers
primarily in Northeastern Michigan. Although the loan portfolio is diversified,
a substantial portion of its debtors' ability to honor their contracts is
dependent upon the tourism industry. Primarily all installment and residential
loans are secured by personal property and real estate. Approximately 96% of the
commercial loans are secured by business assets and the remaining 4% are largely
unsecured.
 
     The Bank's revenues primarily arise from interest income from residential
mortgage lending activities, investments and revenue derived from mortgage
banking through origination of, and sales of mortgage loans to the secondary
market with servicing retained, and related servicing income. The Bank maintains
eleven branches within Iosco, Ogemaw, Alpena, Presque Isle, Alcona and
Montmorency counties of Michigan.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The following summarize the significant accounting and reporting policies
used in the preparation of the consolidated financial statements:
 
     Use of Estimates in Preparing Financial Statements: The preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts of assets, liabilities, disclosure of contingent assets and liabilities
at the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates. The primary estimates incorporated into the Corporation's financial
statements which are susceptible to change in the near term include the
allowance for loan losses, the determination and carrying value of impaired
loans, the determination and carrying value of intangibles, the determination
and carrying value of certain financial instruments and the realization of
deferred tax assets.
 
     Securities: At December 31, 1993, the Corporation adopted Statement of
Financial Accounting Standards No. 115, Accounting for Certain Investments in
Debt and Equity Securities (SFAS No. 115). As required by SFAS No. 115,
securities classified as available for sale are reported at their fair value and
the related unrealized holding gain or loss is reported, net of related income
tax effects, as a separate component of shareholders' equity, until realized.
Securities available for sale consist of those securities not classified as held
to maturity. Such securities might be sold prior to maturity due to changes in
interest rates, prepayment risks, yield and availability of alternative
investments, liquidity needs or other factors. Securities for which management
has the positive intent and the Corporation has the ability to hold to maturity
are reported at amortized cost.
 
     Premiums and discounts on securities are recognized in interest income
using the interest method over the period to maturity. Gains and losses on the
sale of securities available for sale are determined using the specific
identification method.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED

     Loans and Interest and Fees on Loans: Loans are stated at their principal
amount outstanding. Interest on loans is accrued over the term of the loan based
upon the amount of the principal outstanding. The accrual of interest is
discontinued on a loan when management believes serious doubt exists as to the
collectibility of the loan principal or interest. Loan fees and certain direct
loan origination costs are deferred and amortized into interest income over the
term of the loans using the level yield method.
 
     Allowance for Loan Losses: Because some loans may not be repaid in full, an
allowance for loan losses is recorded. Increases to the allowance are recorded
by a provision for possible loan losses charged to expense. Estimating the risk
of loss and the amount of loss on any loan is necessarily subjective.
Accordingly, the allowance is maintained by management at a level considered
adequate to cover possible losses that are currently anticipated based on past
loss experience, general economic conditions, information about specific
borrower situations including their financial position and collateral values,
and other factors and estimates which are subject to change over time. While
management may periodically allocate portions of the allowance for specific
problem loan situations, the whole allowance is available for any loan
charge-offs that occur. A loan is charged off by management as a loss when
deemed uncollectible, although collection efforts continue and further
recoveries may occur.
 
     Statement of Financial Accounting Standards No. 114, Accounting by
Creditors for Impairment of a Loan (SFAS No. 114), as amended by SFAS No. 118,
was adopted by the Corporation on January 1, 1995. Under this Standard, loans
considered to be impaired are reduced to the present value of expected future
cash flows or to the fair value of collateral, by allocating a portion of the
allowance for loan losses to such loans. If these allocations cause the
allowance for loan losses to require an increase, such an increase is reported
as bad debt expense. The adoption of this Standard was immaterial to the 1995
consolidated financial statements.
 
     The carrying values of impaired loans are periodically adjusted to reflect
cash payments, revised estimates of future cash flows, and increases in the
present value of expected cash flows due to the passage of time. Cash payments
representing interest income are reported as such. Other cash payments are
reported as reductions in the carrying value of the loan. Increases or decreases
due to changes in estimates of future payments and due to the passage of time
are reported within the provision for loan losses.
 
     The Corporation has defined "impaired loans" as those loans for which it is
probable that all principal and interest due will not be repaid in accordance
with the original loan agreement. The Corporation has set minimum balance and
condition requirements before a loan may be considered to be impaired.
 
     Loans Held for Sale: Mortgage loans originated and intended for sale in the
secondary market are carried at the lower of cost or market value in the
aggregate. Net unrealized losses are recognized in a valuation allowance by
adjustments to income.
 
     Premises and Equipment: Premises and equipment are stated at cost less
accumulated depreciation and amortization. Depreciation and amortization are
provided primarily on the straight-line basis over the estimated useful lives of
the assets. Maintenance and repairs are expensed and major improvements are
capitalized. At the time of sales or disposition of an asset, the applicable
cost and accumulated depreciation amounts are removed from the books.
 
     Other Real Estate: Other real estate includes properties acquired through,
or in lieu of, loan foreclosure and are initially recorded at fair value at the
date of foreclosure establishing a new cost basis. After foreclosure, valuations
are periodically performed by management and the real estate is carried at the
lower of carrying amount or fair value less costs to sell. Revenue and expenses
from operations and changes in the valuation allowance are included in loss on
other real estate.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED
     Intangible Assets and Goodwill: The value of core deposits acquired in a
1995 branch acquisition are amortized on an accelerated method over their
expected lives. The excess of purchase price over the fair value of assets and
liabilities acquired (goodwill) is amortized on a straight-line basis over 12
years.
 
     Income Taxes: In 1995, the Corporation retroactively adopted Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS No.
109), by restating 1991 and subsequent years. The Corporation records income tax
expense based on the amount of taxes due on its tax return plus deferred taxes
computed based on the expected future tax consequences of temporary differences
between the carrying amounts and tax bases of assets and liabilities, using
enacted tax rates. As changes in tax laws or rates are enacted, deferred tax
assets and liabilities are adjusted through the provision for income taxes.
 
     Net Income (Loss) Per Common Share: Net income (loss) per common share is
based on the weighted average common shares outstanding during the years
presented, retroactively adjusted for a two-for-one stock split effected
December 31, 1993. The stock split was recorded at par value. Beginning in 1994,
Employee Stock Ownership Plan shares are considered outstanding for net
income(loss) per share calculations as they are committed to be released;
unallocated shares are not considered outstanding. The weighted average number
of common shares used in the per share computations were 481,759 in 1995,
472,876 in 1994 and 482,532 in 1993.
 
     Statement of Cash Flows: For purposes of this statement, cash and cash
equivalents include cash on hand, demand deposits in other institutions, federal
funds sold and short-term investments. The Corporation reports net cash flows
for customer loan and deposit transactions.
 
     Impact of New Accounting Standards: The following new accounting standards
have been issued by the Financial Accounting Standards Board that will apply in
1996. Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets, requires a review of long-term assets for
impairment of recorded value and resulting write-downs if value is impaired.
Statement of Financial Accounting Standards No. 122, Accounting for Mortgage
Servicing Rights, requires recognition of an asset when servicing rights are
retained on in-house originated loans that are sold. Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation, requires
proforma disclosure of the effect on net income of valuing future option grants
at their estimated fair value. These Statements are not expected to have a
material effect on the Corporation's financial position or results of
operations.
 
     Reclassification: Certain reclassifications have been made to prior period
consolidated financial statements to place them on a basis comparable with the
current year's consolidated financial statements.
 
NOTE 3 -- CASH AND DUE FROM BANKS
 
     Included in cash and due from banks are amounts required to be deposited
with the Federal Reserve Bank. These reserve balances vary, depending on the
level of customer deposits in the Corporation's subsidiary bank. At December 31,
1995 and 1994, the Federal Reserve balances were $717,000 and $694,000,
respectively.

     Transfer of Securities from HTM to AFS: Effective in May 1995, the entire
portfolio of securities held to maturity were reclassified as securities
available for sale. The amount of securities transferred had a book value of
$30,249,000, a fair value of $29,499,000, and a net unrealized loss of $750,000
at the time of transfer. Management believes that classification of all
securities as available for sale will provide the Bank with greater flexibility
in managing the Bank's assets and liabilities.

Corporation's notification to the FHLB of their intent to prepay.
 
NOTE 11 -- EMPLOYEE BENEFIT PLANS
 
     The Corporation maintains an Employee Stock Ownership Plan (ESOP), which
invests primarily in stock of North Bank Corporation. The ESOP is a stock bonus
and defined contribution plan covering substantially all full-time employees
ages 21 or older, having completed one full year of service. In accordance with
the terms of the ESOP, employees may make voluntary contributions to the Plan of
up to 10 percent of eligible compensation, subject to certain limitations. The
Corporation will match employee contributions equal to the greater of 50% of the
first 6% of compensation deferred by the participant or a discretionary amount
determined by the employer. The Corporation may also make a supplemental
matching contribution to the Plan in an amount determined by the employer. The
Corporation's contributions for 1995 and 1994 were $62,000 and $49,000,
respectively. At December 31, 1995, 48,114 shares were allocated to individual
participants under the plan.
 
     The ESOP had a loan from a commercial bank which was paid off during 1995.
Accordingly, the Corporation had guaranteed the ESOP's debt. As loan payments
were made, unallocated shares were released and allocated to plan participants.
The ESOP's repayments of the debt were made from the contributions and dividends
on stock it received from the Corporation.
 
     The Corporation has a stock option plan, adopted by shareholders in 1993,
which provides for the grant of a maximum of 20,000 shares of the Corporation's
common stock to certain officers and employees at a price which is not less than
the fair market value of the stock at the time the options are granted. The

     Nonqualified stock options were granted to an officer of the Corporation
during 1993. The options cover 4,000 shares of common stock at the price of
$15.13 and expire in 1998. At December 31, 1995, the options had not been
exercised.
 
     The Corporation sponsored a non-contributory, defined benefit pension plan
covering substantially all employees. On December 31, 1994, the Corporation
curtailed the defined benefit pension plan, which resulted in the freezing of
benefits as of that date. The net loss due to the plan curtailment was $72,230
for 1994. During December 1995, the Corporation terminated the plan and settled
$1,103,000 of the accumulated benefit obligation by making cash payments to plan
participants and purchasing nonparticipating annuity contracts. The remaining
accumulated benefit obligation is expected to be settled by April 1996. Defined
benefits were not provided under any successor plan. The net loss due to the
plan settlement was $773,910 for 1995.
 
     The following sets forth the plan's funded status and amounts recognized in
the consolidated balance sheets at December 31, in thousands:

     In accordance with the provisions of Statement of Financial Accounting
Standards No. 87, the Corporation recorded an additional minimum pension
liability adjustment in 1994 representing the excess of the accumulated benefit
obligation over the fair value of plan assets plus the amount recognized as
prepaid pension costs. The additional minimum pension liability was included in
"Other liabilities". This transaction, which had no impact on earnings, resulted
in a reduction of shareholders' equity in 1994 of $332,640, net of tax.
 
     A weighted average discount rate of 7% was used in determining the
actuarial present value of the accumulated benefit obligation in 1995 and 1994.
The expected long-term rate of return on plan assets was 9% in both years.
 
NOTE 12 -- RELATED PARTY TRANSACTIONS
 
     The Corporation enters into transactions with certain executive officers,
directors, and their related interests. Included in these transactions are loans
which amounted to approximately $130,000 and $309,000 at December 31, 1995 and
1994, respectively. Deposit accounts with the same individuals amounted to
$549,324 and $492,863 at December 31, 1995 and 1994, respectively.
 
NOTE 13 -- COMMITMENTS AND CONTINGENCIES
 
     From time to time, the Corporation is involved in legal matters in the
ordinary course of business. Management believes that the ultimate resolution of
such matters will not have a material effect on the consolidated financial
statements.
 
     The Bank is a party to financial instruments with off-balance sheet risk in
the normal course of business to meet financing needs of its customers. These
financial instruments include commitments to make loans and unused lines of
credit. The Bank follows the same credit policy to make such commitments as is
followed for loans and investments recorded in the consolidated financial
statements.
 
     As of December 31, 1995, the Bank has outstanding commitments to make loans
of which 67% are at fixed rates. These interest rates range from 8.25% to 9.75%.
The Bank also funds unused lines of credit of which 26% are at fixed rates. The
fixed interest rates on the line of credits range from 6.20% to 11.75%.
 
     Outstanding commitments at December 31 were as follows:

NOTE 15 -- DISCLOSURES REGARDING FAIR VALUE OF FINANCIAL INSTRUMENTS (IN
THOUSANDS)
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments:
 
     Cash and Short-Term Investments: For these short-term instruments, the
carrying amount is a reasonable estimate of fair value.
 
     Securities: For securities, fair value is based upon market price quotes
from brokers utilizing pricing formulas.
 
     Loans: The fair value of loans is estimated by discounting future cash
flows using the current rates at which similar loans would be made to borrowers
with similar credit ratings and for the same remaining maturities.
 
     Deposit Liabilities: The fair value of demand deposits, savings accounts,
and certain money market deposits is the amount payable on demand at the
reporting date. The fair value of fixed-maturity certificates of deposit is
estimated by discounting future cash flows using the rates currently offered for
deposits of similar remaining maturities.
 
     Long-Term Borrowings: The fair value of FHLB advances is estimated by
discounting future cash flows using rates currently offered for similar terms.

     Commitments to Extend Credit and Standby Letters of Credit: The fair value
of commitments is estimated using the fees currently charged to enter similar
agreements, taking into account the remaining terms of the agreements and the
present creditworthiness of the counterparties. For fixed-rate loan commitments,
fair value also considers the difference between current levels of interest
rates and the committed rates. The fair value of letters of credit is based on
fees currently charged for similar agreements or on the estimated costs to
terminate them or otherwise settle the obligations with the counterparties at
the reporting date. The fair values associated with these financial instruments
are immaterial at December 31, 1995 and 1994.
 
     The estimated fair values of the Corporation's financial instruments are as

NOTE 16 -- RESTRICTIONS ON SUBSIDIARY DIVIDENDS
 
     Banking laws and regulations restrict the amount the Bank can transfer to
the Corporation in the form of cash dividends. At December 31, 1995, $3.6
million of retained earnings of the Bank was available for distribution to the
Corporation as dividends without prior regulatory approval. It is not the intent
of management to pay dividends in amounts which would reduce the capital of the
Bank to a level below that which is considered prudent by management and in
accordance with the guidelines of regulatory authorities.
 
NOTE 17 -- PENDING MERGER
 
     In February 1996, the Corporation entered into a definitive agreement to be
acquired by Independent Bank Corporation of Ionia, Michigan (a publicly-traded
corporation). The purchase price is estimated to be $33 per share of North Bank
Corporation common stock. The acquisition is subject to both regulatory and
shareholder approval and is expected to be completed during the second quarter
of 1996.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
   
     The Articles of Incorporation of the Company provide that its directors and
officers are to be indemnified as of right to the fullest extent permitted under
the Michigan Business Corporation Act ("MBCA"). Under the MBCA, directors,
officers, employees or agents are entitled to indemnification against expenses
(including attorneys' fees) whenever they successfully defend legal proceedings
brought against them by reason of the fact that they hold such a position with
the corporation. In addition, with respect to actions not brought by or in the
right of the corporation, indemnification is permitted under the MBCA for
expenses (including attorneys' fees), judgments, fines, penalties and reasonable
settlement if it is determined that the person seeking indemnification acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the corporation or its shareholders and, with respect
to criminal proceedings, he or she had no reasonable cause to believe that his
or her conduct was unlawful. With respect to actions brought by or in the right
of the corporation, indemnification is permitted under the MBCA for expenses
(including attorneys' fees) and reasonable settlements, if it is determined that
the person seeking indemnification acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation or its shareholders; provided, indemnification is not permitted if
the person is found liable to the corporation, unless the court in which the
action or suit was brought has determined that indemnification is fair and
reasonable in view of all the circumstances of the case.
    
 
     The MBCA specifically provides that it is not the exclusive source of
indemnity. As a result, the Company adopted individual indemnification
agreements with its directors. Approved by the Company's shareholders, the
indemnification agreements provide a contractually enforceable right for prompt
indemnification, except that indemnification is not required where: (i)
indemnification is provided under an insurance policy, except for amounts in
excess of insurance coverage; (ii) indemnification is provided by the Company
outside of the agreement; (iii) the claim involved a violation of Section 16(b)
of the Securities Exchange Act of 1934 or similar provision of state law; or
(iv) indemnification by the Company is otherwise prohibited by law. In the case
of a derivative or other action by or in the right of the Company where a
director is found liable, indemnity is predicated on the determination that
indemnification is nevertheless appropriate, by majority vote of a committee of
disinterested directors, independent legal counsel, or a court where the claim
is litigated, whichever the indemnitee chooses. The protection provided by the
indemnification agreements is broader than that under the MBCA, where
indemnification in such circumstances is available only where specifically
authorized by the court where the claim is litigated.
 
                                      II-1
<PAGE>   129
 
     In addition to the available indemnification, the Company's Articles of
Incorporation, as amended, limit the personal liability of the members of its
Board of Directors for monetary damages with respect to claims by the Company or
its shareholders resulting from certain negligent acts or omissions.
 
     Under an insurance policy maintained by the Company, the directors and
officers of the Company are insured within the limits and subject to the
limitations of the policy, against certain expenses in connection with the
defense of certain claims, actions, suits or proceedings, and certain
liabilities which might be imposed as a result of such claims, action, suits or
proceedings, which may be brought against them by reason of being or having been
such directors and officers.
 
   
     Under the Trust Agreement, the Company will agree to indemnify each of the
Trustees of IBC Capital or any predecessor Trustee for IBC Capital, and to hold
each Trustee harmless against, any loss, damage, claims, liability or expense
incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the Trust Agreement,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties under the Trust Agreement.
    
 
   
     The Company and IBC Capital have agreed to indemnify the Underwriter, and
the Underwriter has agreed to indemnify IBC Capital and the Company against
certain civil liabilities, including liabilities under the Securities Act of
1933, as amended. Reference is made to the Underwriting Agreement filed as
Exhibit 1 herewith.
    
 
ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.
 
     Reference is made to the Exhibit Index which appears at page II-4 of the
Registration Statement.
 
ITEM 17. UNDERTAKINGS.
 
     Insofar as indemnification for liabilities under the Securities Act of
1933, as amended (the "Act") may be permitted to directors, officers and
controlling persons of the Company pursuant of the foregoing provisions, or
otherwise, the Company has been advised that, in the opinion of the Securities
and Exchange Commission such indemnification is against the 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 Company 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 Company 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 Company hereby undertakes that: (1) For purposes of
determining any liability under the Act, the information omitted from the form
of prospectus filed as part of this Registration Statement in reliance upon Rule
430A and contained in a form of prospectus filed by the Company pursuant to Rule
424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part
of this Registration Statement as of the time it was declared effective; and (2)
For the purpose of determining any liability under the Act, each post-effective
amendment that contains a form of prospectus 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.

                                                               November __, 1996


STIFEL, NICOLAUS & COMPANY, INCORPORATED
500 North Broadway
St. Louis, Missouri 63102

Dear Sirs:

   Independent Bank Corporation, a Michigan corporation (the "Company") and its
financing subsidiary, IBC Capital Finance ("IBC Capital"), a Delaware business
trust (the "Trust", and hereinafter together with the Company, the "Offerors"),
propose that the Trust issue and sell severally to Stifel, Nicolaus & Company,
Incorporated (the "Underwriter"), pursuant to the terms of this Agreement, the
Trust's ____% Cumulative Trust Preferred Securities, with a liquidation
preference of $25.00 per preferred security (the "Preferred Securities"), to be
issued under a Certificate of Designations (the "Certificate of Designations"),
the terms of which are more fully described in the Prospectus (as hereinafter
defined).  The aforementioned 600,000 Preferred Securities to be sold to the
Underwriter are herein called the "Firm Shares".  Solely for the purpose of
covering over-allotments in the sale of the Firm Shares, the Offerors further
propose that the Trust issue and severally sell to the Underwriter, at its
option, up to an additional 90,000 Preferred Securities (the "Option Shares")
upon exercise of the over-allotment option granted in Section 1 hereof.  The
Firm Shares and any Option Shares are herein collectively referred to as the
"Shares".


   The Offerors hereby confirm as follows their agreement with the Underwriter
in connection with the proposed purchase of the Shares.

<PAGE>   2


   1.  SALE, PURCHASE AND DELIVERY OF SHARES; DESCRIPTION OF SHARES.

   (a)  On the basis of the representations, warranties and agreements herein
contained, and subject to the terms and conditions herein set forth, the
Offerors hereby agree that the Trust shall issue and severally sell to the
Underwriter and the Underwriter agrees to purchase from the Trust, at a
purchase price per share of $25.00 (the "Purchase Price") the Firm Shares, and
the Company shall pay to the Underwriter a commission in the amount set forth
in Schedule 1 hereto.

   In addition, on the basis of the representations, warranties and agreements
herein contained and subject to the terms and conditions herein set forth, the
Offerors hereby grant to the Underwriter, an option to purchase all or any
portion of the 90,000 Option Shares, and upon the exercise of such option in
accordance with this Section 1, the Offerors hereby agree that the Trust shall
sell to the Underwriter, and the Underwriter agrees to purchase from the Trust,
all or any portion of the Option Shares at the same Purchase Price per share
paid for the Firm Shares.  The option hereby granted (the "Option") shall
expire 30 days after the date upon which the Registration Statement (as
hereinafter defined) becomes effective and may be exercised only for the
purpose of covering over-allotments which may be made in connection with the
offering and distribution of the Firm Shares.  The Option may be exercised in
whole or in part at any time (but not more than once) by you giving notice
(confirmed in writing) to the Company setting forth the number of Option Shares
as to which the Underwriter is exercising the Option and the time, date and
place for payment and delivery of certificates for such Option Shares.  Such
time and date of payment and delivery for the Option Shares (the "Option
Closing Date") shall be determined by you, but shall not be earlier than two
nor later than five full business days after the exercise of such Option, nor
in any event prior to the Closing Date (as hereinafter defined).  The Option
Closing Date may be the same as the Closing Date.

   Payment of the Purchase Price and delivery of certificates for the Firm
Shares shall be made at the offices of the Underwriter, 500 North Broadway, St.
Louis, Missouri 63102, or such other place as shall be agreed to by you and the
Company, at 10:00 a.m., St. Louis time, on _____ __, 1996, or at such other
time not more than five full business days thereafter as the Company and you
shall determine (the "Closing Date").  If the Underwriter exercises the option
to purchase any or all of the Option Shares, payment of the Purchase Price and
delivery of certificates for such Option Shares shall be made on the Option
Closing Date at the offices of the Underwriter, or at such other place as the
Company and you shall determine.  Such payments shall be made to the Company or
its order by wire transfer or certified or bank cashier's check, in clearing
house or similar immediately available funds, in the amount of the Purchase
Price therefor, against

                                       2
<PAGE>   3


delivery by or on behalf of the Company to you for the Underwriter of
certificates for the Shares to be purchased by the Underwriter.

   The Agreement contained herein with respect to the timing of the Closing
Date and Option Closing Date is intended to, and does, constitute an express
agreement, as described in Rule 15c6-1(c) and (d) promulgated under the 1934
Act (as defined herein), for a settlement date other than four business days
after the date of the contract.

   Certificates for Shares to be purchased by the Underwriter shall be
delivered in fully registered form in such authorized denominations and
registered in such names as you shall request not later than 12:00 noon, St.
Louis time, two business days prior to the Closing Date and, if applicable, the
Option Closing Date.  Certificates for Shares to be purchased by the
Underwriter shall be made available to you for inspection, checking and
packaging at such office as you may designate not later than 1:00 p.m., St.
Louis time, on the last business day prior to the Closing Date and, if
applicable, on the last business day prior to the Option Closing Date.

   Time shall be of the essence, and delivery of the certificates for the
Shares at the time and place specified pursuant to this Agreement is a further
condition of the obligations of the Underwriter hereunder.

   (b) The Offerors propose that the Trust issue the Shares pursuant to an
Amended and Restated Trust Agreement among State Street Bank and Trust Company,
as Property Trustee, Wilmington Trust Company, as Delaware Trustee, the
Administrative Trustees named therein, and the Company in substantially the
form heretofore delivered to you, said Agreement being hereinafter referred to
as the "Trust Agreement".  In connection with the issuance of the Shares, the
Company proposes (i) to issue its Junior Subordinated Deferrable Interest
Debentures ( the "Debentures") pursuant to an Indenture, dated as of
_____________, 1996, between the Company and ________________________ as
Trustee (the "Indenture") and (ii) to guarantee the Shares pursuant to a
Guarantee Agreement between the Company and State Street Bank and Trust
Company, as guarantee trustee (the "Guarantee"), to the extent described
therein.

   2.  REPRESENTATIONS AND WARRANTIES.

   (a)   The Offerors jointly and severally represent and warrant to, and agree
with, the Underwriter that:

                      (i)         The reports filed with the Securities and
         Exchange Commission (the "Commission") by the Company under the
         Securities

<PAGE>   4


         Exchange Act of 1934, as amended (the "1934 Act") and the rules and
         regulations thereunder (the "1934 Act Regulations") at the time they
         were filed with the Commission, complied as to form in all material
         respects with the requirements of the 1934 Act and the 1934 Act
         Regulations and did not contain an untrue statement of a material fact
         or omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the
         circumstances in which they were made, not misleading.

                      (ii)        The Offerors have prepared and filed with the
         Commission a registration statement on Form S-2 (File No.  33-_______)
         for the registration of the Shares, the Guarantee and $_______ million
         aggregate principal amount of Debentures under the Securities Act of
         1933, as amended (the "1933 Act"), including the related prospectus
         subject to completion, and one or more amendments to such registration
         statement may have been so filed, in each case in conformity in all
         material respects with the requirements of the 1933 Act, the rules and

         the Trust Indenture Act of 1939, as amended (the "Trust Indenture

         delivered by the Company to the Underwriter.  After the execution of
         this Agreement, the Offerors will file with the Commission (A) if such
         registration statement, as it may have been amended, has been declared
         by the Commission to be effective under the 1933 Act, a prospectus in

         statement (or, if no such amendment shall have been filed, in such
         registration statement), with such changes or insertions as are
         required by Rule 430A of the 1933 Act Regulations ("Rule 430A") or

         prior to (or as are agreed to by the Underwriter subsequent to) the
         execution of this Agreement, or (B) if such registration statement, as
         it may have been amended, has not been declared by the Commission to
         be effective under the 1933 Act, an amendment to such registration
         statement, including a form of final prospectus, necessary to permit
         such registration statement to become effective, a copy of which
         amendment has been furnished to and not objected to by the Underwriter
         prior to (or is agreed to by the Underwriter subsequent to) the
         execution of this Agreement.  The Offerors will not file any amendment
         to the registration statement or any amended Preliminary Prospectus or
         any amendment thereto, of which you have not been previously furnished
         a copy or to which you or your counsel shall reasonably object.  As
         used in this Agreement, the

         statement or any amendment thereto including all documents (or
         portions thereof) incorporated by reference therein under the 1934 Act
         (including the prospectus subject to completion, if any, included in
         the Registration Statement and each prospectus filed pursuant to Rule
         424(a) under the 1933 Act); and the term "Prospectus" means the
         prospectus first filed with the Commission pursuant to Rule 424(b)(1)

         Statement, in each case including the financial schedules and all
         documents (or portions thereof) incorporated by reference therein
         under the 1934 Act.  The date on which the Registration Statement
         becomes effective is hereinafter referred to as the "Effective Date."

                    (iii)         The documents incorporated by reference in
         the Preliminary Prospectus or Prospectus or from which information is

         respects with the requirements of the 1934 Act and the 1934 Act
         Regulations, and when read together and with the other information in
         the Preliminary Prospectus or Prospectus, as the case may be, at the
         time the Registration Statement became or becomes effective and at the
         Closing Date and any Option Closing Date, did not or will not, as the
         case may be, contain an untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein, in light of the circumstances in which
         they were made, not misleading.

                      (iv)        No order preventing or suspending the use of
         any Prospectus (or, if the Prospectus is not in existence, the most
         recent Preliminary Prospectus) has been issued by the Commission, nor
         has the Commission, to the knowledge of the Offerors, threatened to
         issue such an order or instituted proceedings for that purpose.  Each
         Preliminary Prospectus, at the time of filing thereof, (A) complied in
         all material respects with the requirements of the 1933 Act and the
         1933 Act Regulations and (B) did not contain an untrue statement of a

<PAGE>   6


         made, not misleading; provided, however, that this representation and
         warranty does not apply to statements or omissions made in reliance
         upon and in conformity with information furnished in writing to the
         Offerors by you expressly for inclusion in the Prospectus beneath the
         heading "Underwriting" (such information referred to herein as the
         "Underwriter's Information").


                      (v)         At the Effective Date and at all times
         subsequent thereto, up to and including the Closing Date and, if
         applicable, the Option Closing Date, the Registration Statement and
         any post-effective amendment thereto (A) complied and will comply in
         all material respects with the requirements of the 1933 Act, the 1933
         Act Regulations and the Trust Indenture Act (and the rules and
         regulations thereunder) and (B) did not and will not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, not
         misleading.  At the Effective Date and at all times when the
         Prospectus is required to be delivered in connection with offers and
         sales of Shares, including, without limitation, the Closing Date and,
         if applicable, the Option Closing Date, the Prospectus, as amended or
         supplemented, (A) complied and will comply in all material respects
         with the requirements of the 1933 Act and the 1933 Act Regulations and
         the Trust Indenture Act (and the rules and regulations thereunder) and
         (B) did not contain and will not contain an untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading; provided,
         however, that this representation and warranty does not apply to
         Underwriter's Information.

                      (vi)        The Company is duly organized, validly
         existing and in good standing under the laws of the State of Michigan,
         with full corporate and other power and authority to own, lease and
         operate its properties and conduct its business as described in and
         contemplated by the Registration Statement and the Prospectus (or, if
         the Prospectus is not in existence, the most recent Preliminary
         Prospectus) and as currently being conducted and is duly registered as
         a bank holding company under the Bank Holding Company Act of 1956, as
         amended (the "BHC Act").

                                  The Trust has been duly created and is
         validly existing as a statutory business trust in good standing under
         the Delaware Business Trust Act with the power and authority (trust
         and other) to own its property and conduct its business as described
         in the Registration Statement and Prospectus, to issue and sell the
         Shares and to enter into and perform its

                                       6
<PAGE>   7


         obligations under this Agreement and to consummate the transactions
         herein contemplated; the Trust has no subsidiaries and is duly
         qualified to transact business and is in good standing in each
         jurisdiction in which the conduct of its business or the ownership of
         its property requires such qualification, except to the extent that
         the failure to be so qualified or be in good standing would not have a
         material adverse effect on the Trust; the Trust has conducted and will
         conduct no business other than the transactions contemplated by this
         Agreement and described in the Prospectus; the Trust is not a party to
         or bound by any agreement or instrument other than this Agreement, the
         Trust Agreement and the agreements and instruments contemplated by the
         Trust Agreement and described in the Prospectus; the Trust has no
         liabilities or obligations other than those arising out of the
         transactions contemplated by this Agreement and the Trust Agreement
         and described in the Prospectus; the Trust is not a part to or subject
         to any action, suit or proceeding of any nature; the Trust is not, and
         at the Closing Date or any Option Closing Date will not be, classified
         as an association taxable as a corporation for United States federal
         income tax purposes; and the Trust is, and as of the Closing Date or
         any Option Closing Date will be, treated as a consolidated subsidiary
         of the Company pursuant to generally accepted accounting principles.

                    (vii)         The Company has five subsidiaries.  They are
         Independent Bank, Independent Bank West Michigan, Independent Bank
         South Michigan, Independent Bank East Michigan (the "Banks") and the
         Trust.  The Company does not own or control, directly or indirectly,
         more than 5% of any class of equity security of any corporation,
         association or other entity other than the Banks, Independent Title
         Services, Inc., IBC Financial Services, Inc. and the Trust.  Each of
         the Banks is a Michigan State Bank duly incorporated, validly existing
         and in good standing under the laws of Michigan.  Each Bank has full
         corporate and other power and authority to own, lease and operate its
         properties and to conduct its business as described in and
         contemplated by the Registration Statement and the Prospectus (or, if
         the Prospectus is not in existence, the most recent Preliminary
         Prospectus) and as currently being conducted.  Each Bank is a member
         of the Federal Reserve System, and no proceedings for the termination
         or revocation of such membership are pending or, to the knowledge of
         the Company, threatened.  The deposit accounts of each Bank are
         insured by the Bank Insurance Fund administered by the Federal Deposit
         Insurance Corporation (the "FDIC") up to the maximum amount provided
         by law, except to the extent the Prospectus discloses such deposit
         accounts are insured by the Savings Association Insurance Fund
         administered by the FDIC ("SAIF") and to such extent the deposit
         accounts are so insured up to the maximum amount provided by law; and
         no proceedings for the modification,

                                       7
<PAGE>   8


         termination or revocation of any such insurance are pending or, to the
         knowledge of the Company, threatened.

                   (viii)         Each of the Company and the Banks is duly
         qualified to transact business as a foreign corporation and is in good
         standing in each other jurisdiction in which it owns or leases
         property or conducts its business so as to require such qualification
         and in which the failure to so qualify would, individually or in the
         aggregate, have a material adverse effect on the condition (financial
         or otherwise), earnings, business, prospects or results of operations
         of the Company and the Banks on a consolidated basis.  All of the
         issued and outstanding shares of capital stock of the Banks (A) have
         been duly authorized and are validly issued, (B) are fully paid and
         nonassessable except to the extent such shares may be deemed
         assessable under 12 U.S.C. Section 55 or 12 U.S.C. Section 1831o, and
         (C) except as disclosed in the Prospectus (or, if the Prospectus is
         not in existence, the most recent Preliminary Prospectus), are
         directly owned by the Company free and clear of any security interest,
         mortgage, pledge, lien, encumbrance, restriction upon voting or
         transfer, preemptive rights, claim or equity.  Except as disclosed in
         the Prospectus, there are no outstanding rights, warrants or options
         to acquire or instruments convertible into or exchangeable for any
         capital stock of the Company and the Banks.

                      (ix)        The capital stock of the Offerors conforms to
         the description thereof contained in the Prospectus (or, if the
         Prospectus is not in existence, the most recent Preliminary
         Prospectus).  The outstanding shares of capital stock of the Offerors
         have been duly authorized and validly issued and are fully paid and
         nonassessable, and no such shares were issued in violation of the
         preemptive or similar rights of any security holder of the Company; no
         person has any preemptive or similar right to purchase any shares of
         capital stock of the Offerors.  Except as disclosed in the Prospectus
         (or, if the Prospectus is not in existence, the most recent
         Preliminary Prospectus), there are no outstanding rights, options or
         warrants to acquire any securities of the Offerors other than options
         issued under the Company's Incentive Share Grant Plan and Employee
         Stock Option Plan, and there are no outstanding securities convertible
         into or exchangeable for any such securities, and no restrictions upon
         the voting or transfer of any capital stock of the Company pursuant to
         the Company's corporate charter or by-laws or any agreement or other
         instrument to which the Company is a party or by which it is bound.

                      (x)         The Trust has all requisite power and
         authority to issue, sell and deliver the Shares in accordance with and
         upon the terms and conditions set forth in this Agreement, the
         Certificate of Designations, the


                                       8

         Registration Statement and the Prospectus (or, if the Prospectus is
         not in existence, the most recent Preliminary Prospectus).  All
         corporate action required to be taken by the Offerors for the
         authorization, issuance, sale and delivery of the Shares in accordance
         with such terms and conditions has been validly and sufficiently
         taken.  The Shares, when delivered in accordance with this Agreement,
         will be duly and validly issued and outstanding, will be fully paid
         and nonassessable undivided beneficial interests in the assets of the
         Trust, will be entitled to the benefits of the Trust Agreement, will
         not be issued in violation of or subject to any preemptive or similar
         rights, and will conform to the description thereof in the
         Registration Statement and the Prospectus (or, if the Prospectus is
         not in existence, the most recent Preliminary Prospectus) and the
         Certificate of Designations.  Holders of the Shares will be entitled
         to the same limitation of personal liability extended to stockholders
         of private for profit corporations organized under the General
         Corporation Law of the State of Delaware.  None of the Shares,
         immediately prior to delivery, will be subject to any security
         interest, lien, mortgage, pledge, encumbrance, restriction upon voting
         or transfer, preemptive rights, claim, equity or other defect.

                                  The Debentures have been duly and validly
         authorized, and, when duly and validly executed, authenticated and
         issued as provided in the Indenture and delivered pursuant to this
         Agreement, will constitute valid and legally binding obligations of
         the Company entitled to the benefits of the Indenture and will conform
         to the description thereof contained in the Prospectus.

                      (xi)        The Offerors and the Banks have complied in
         all material respects with all federal, state and local statutes,
         regulations, ordinances and rules applicable to the ownership and
         operation of their properties or the conduct of their businesses as
         described in and contemplated by the Registration Statement and the
         Prospectus (or, if the Prospectus is not in existence, the most recent
         Preliminary Prospectus) and as currently being conducted.

                    (xii)         The Offerors and the Banks have all material
         permits, easements, consents, licenses, franchises and other
         governmental and regulatory authorizations from all appropriate
         federal, state, local or other public authorities ("Permits") as are
         necessary to own and lease their properties and conduct their
         businesses in the manner described in and contemplated by the
         Registration Statement and the Prospectus (or, if the Prospectus is
         not in existence, the most recent Preliminary Prospectus) and as
         currently being conducted in all material respects.  All such Permits
         are in full force and effect and each of the Company and the Banks are
         in all

                                       9
<PAGE>   10


         material respects complying therewith, and no event has occurred that
         allows, or after notice or lapse of time would allow, revocation or
         termination thereof or will result in any other material impairment of
         the rights of the holder of any such Permit, subject in each case to
         such qualification as may be adequately disclosed in the Prospectus
         (or, if the Prospectus is not in existence, the most recent
         Preliminary Prospectus).  Such Permits contain no restrictions that
         would materially impair the ability of the Company or the Banks to
         conduct their businesses in the manner consistent with their past
         practices.  Neither the Offerors nor the Banks have received notice or
         otherwise has knowledge of any proceeding or action relating to the
         revocation or modification of any such Permit.

                   (xiii)         Neither the Offerors nor any of the Banks is
         in breach or violation of their corporate charter (including without
         limitation, the Certificate of Designations), by-laws or other
         governing documents.  Neither the Offerors nor the Banks are, and to
         the knowledge of the Offerors no other party is, in violation, breach
         or default (with or without notice or lapse of time or both) in the
         performance or observance of any term, covenant, agreement,
         obligation, representation, warranty or condition contained in (A) any
         contract, indenture, mortgage, deed of trust, loan or credit
         agreement, note, lease, franchise, license, Permit or any other
         agreement or instrument to which it is a party or by which it or any
         of its properties may be bound, which such breach, violation or
         default could have material adverse consequences to the Offerors and
         the Banks on a consolidated basis, and to its knowledge, no other
         party has asserted that the Offerors or any of the Banks is in such
         violation, breach or default (provided that the foregoing shall not
         apply to defaults by borrowers from the Banks), or (B) except as
         disclosed in the Prospectus (or, if the Prospectus is not in
         existence, the most recent Preliminary Prospectus), any order, decree,
         judgment, rule or regulation of any court, arbitrator, government, or
         governmental agency or instrumentality, domestic or foreign, having
         jurisdiction over the Offerors or the Banks or any of their respective
         properties the breach, violation or default of which could have a
         material adverse effect on the condition, financial or otherwise,
         earnings, affairs, business, prospects, or results of operations of
         the Offerors and the Banks on a consolidated basis.

                    (xiv)         The execution, delivery and performance of
         this Agreement and the consummation of the transactions contemplated
         by this Agreement, the Certificate of Designations, the Registration
         Statement and the Prospectus (or, if the Prospectus in not in
         existence, the most recent Preliminary Prospectus) do not and will not
         conflict with, result in the creation or imposition of any material
         lien, claim, charge, encumbrance or

                                       10

         or the Shares pursuant to, constitute a breach or violation of, or
         constitute a default under, with or without notice or lapse of time or
         both, any of the terms, provisions or conditions of the charter
         (including without limitation, the Certificate of Designations) or
         by-laws of the Company or the Banks, the Trust Agreement, any
         contract, indenture, mortgage, deed of trust, loan or credit
         agreement, note, lease, franchise, license, Permit or any other
         agreement or instrument to which the Offerors or the Banks is a party
         or by which either of them or any of their respective properties may
         be bound or any order, decree, judgment, rule or regulation of any
         court, arbitrator, government, or governmental agency or

         Offerors or the Bank or any of their respective properties which
         conflict, creation, imposition, breach, violation or default would
         have either singly or in the aggregate a material adverse effect on
         the condition, financial or otherwise, earnings, affairs, business,
         prospects or results of operations of the Offerors and the Banks on a
         consolidated basis.  No authorization, approval, consent or order of,
         or filing, registration or qualification with, any person (including,
         without limitation, any court, governmental body or authority) is
         required in connection with the transactions contemplated by this
         Agreement, the Certificate of Designations, the Registration Statement
         and the Prospectus (or such Preliminary Prospectus), except such as

         state securities laws in connection with the purchase and distribution
         of the Shares by the Underwriter.  No authorization, approval, consent
         or order of or filing, registration or qualification with, any person

         contemplated by this Agreement, the Certificate of Designations, the
         Registration Statement and the Prospectus, except such as have been

         power and authority to enter into this Agreement and this Agreement
         has been duly and validly authorized, executed and delivered by the
         Offerors and constitutes the legal, valid and binding agreement of the
         Offerors, enforceable against Offerors in accordance with its terms,
         except as the enforcement thereof may be limited by general principles
         of equity and by bankruptcy or other laws relating to or affecting
         creditors' rights generally and except as any indemnification or
         contribution provisions thereof may be limited under applicable
         securities laws.  Each of the Indenture, the Trust Agreement, the

         knowledge of the Company, threatened, against or affecting the

         by any court or any regulatory, administrative or governmental
         official, commission, board, agency or other authority or body, or any
         arbitrator, wherein an unfavorable decision, ruling or finding could
         have a material adverse effect on the consummation of this Agreement
         or the transactions contemplated herein or the condition (financial or

         required to be filed as exhibits to the Registration Statement by the
         1933 Act or the 1933 Act Regulations or the Trust Indenture Act (or
         any rules or regulations thereunder) which have not been filed as
         exhibits to the Registration Statement, or that are required to be
         summarized in the Prospectus (or, if the Prospectus is not in
         existence, the most recent Preliminary Prospectus) that are not so
         summarized.

                   (xxii)         The Offerors have not taken, directly or
         indirectly, any action designed to result in or which has constituted
         or which might reasonably be expected to cause or result in
         stabilization or manipulation of the price of any security of the
         Offerors to facilitate the sale or resale of the

         marks, trade names and other rights necessary to conduct the

         Offerors nor the Banks have received any notice of infringement or
         conflict with asserted rights of others with respect to any patents,
         copyrights, trademarks, service marks, trade names or other rights
         which, individually or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would have a material adverse
         effect on the condition (financial or otherwise), earnings, affairs,
         business, prospects or results of operations of the Offerors and the
         Banks on a consolidated basis, and the Company does not know of any
         basis for any such infringement or conflict.

                   (xxiv)         Except as adequately disclosed in the
         Prospectus (or, if the Prospectus is not in existence, the most recent
         Preliminary Prospectus), no labor dispute involving the Company or the
         Banks exists or, to the knowledge of the Company, is imminent which
         might be expected to have a material adverse effect on the condition
         (financial or otherwise), earnings, affairs, business, prospects or
         results of operations of the Offerors and the Banks on a consolidated
         basis or which is required to be disclosed in the Prospectus (or, if
         the Prospectus is not in existence, the most recent Preliminary
         Prospectus).  Neither the Company nor the Banks have received notice
         of any existing or threatened labor dispute by the employees of any of
         its principal suppliers, customers or contractors which might be
         expected to have a material adverse effect on the condition (financial
         or otherwise), earnings, affairs, business, prospects or results of
         operations of the Company and the Banks on a consolidated basis.

                    (xxv)         The Offerors and the Banks have timely and
         properly prepared and filed all necessary federal, state, local and
         foreign tax returns which are required to be filed and have paid all
         taxes shown as due thereon and have paid all other taxes and
         assessments to the extent that the same shall have become due, except
         such as are being contested in good faith or where the failure to so
         timely and properly prepare and file would not have a material adverse
         effect on the condition (financial or otherwise), earnings, affairs,
         business, prospects or results of operations of the Offerors and the
         Banks on a consolidated basis.  The Company has no knowledge of any
         tax deficiency which has been or might be assessed against the
         Offerors or the Banks which, if the subject of an unfavorable
         decision, ruling or finding, would have a material adverse effect on
         the condition (financial or otherwise), earnings, affairs, business,
         prospects or results of operations of the Offerors and the Banks on a
         consolidated basis.

                   (xxvi)         Each of the material contracts, agreements
         and instruments described or referred to in the Registration Statement
         or the Prospectus (or, if the Prospectus is not in existence, the most
         recent Preliminary Prospectus) and each contract, agreement and
         instrument filed as an exhibit to the Registration Statement is in
         full force and effect and is the legal, valid and binding agreement of
         the Offerors or the Banks, enforceable in accordance with its terms,
         except as the enforcement thereof may be limited by general principles
         of equity and by bankruptcy or other laws relating to or affecting
         creditors' rights generally.  Except as disclosed in the Prospectus
         (or such Preliminary Prospectus), to the knowledge of the Company, no
         other party to any such agreement is (with or without notice or lapse
         of time or both) in breach or default in any material respect
         thereunder.

                   (xxvii)        No relationship, direct or indirect, exists
         between or among the Offerors or the Banks, on the one hand, and the
         directors, officers, stockholders, customers or suppliers of the
         Offerors or the Banks, on the other hand, which is required to be
         described in the Registration Statement and the Prospectus (or, if the
         Prospectus is not in existence, the most recent Preliminary
         Prospectus) which is not adequately described therein.

                 (xxviii)         No person has the right to request or require
         the Offerors or the Banks to register any securities for offering and
         sale under the 1933 Act by reason of the filing of the Registration
         Statement with the Commission or the issuance and sale of the Shares
         except as adequately disclosed in the Registration Statement and the
         Prospectus (or, if the Prospectus is not in existence, the most recent
         Preliminary Prospectus).

                   (xxix)         The Shares have been approved for quotation
         on the Nasdaq National Market subject to official notice of issuance.

                    (xxx)         Except as described in the Prospectus (or, if
         the Prospectus is not in existence, the most recent Preliminary
         Prospectus), there are no contractual encumbrances or restrictions or
         material legal restrictions, on the ability of the Banks or the Trust
         (A) to pay dividends or make any other distributions on its capital
         stock or to pay any indebtedness owed to the Company, (B) to make any
         loans or advances to, or investments in, the Company or (C) to
         transfer any of its property or assets to the Company.

                   (xxxi)         Neither of the Offerors is an "investment
         company" within the meaning of the Investment Company Act of 1940, as
         amended.

                   (xxxii)        The Company has not distributed and will not
         distribute prior to the Closing Date any prospectus in connection with
         the Offering, other than a Preliminary Prospectus, the Prospectus, the
         Registration Statement and the other materials permitted by the 1933
         Act and the 1933 Act Regulations and reviewed by the Underwriter.

                 3.       OFFERING BY THE UNDERWRITER.  After the Registration
Statement becomes effective or, if the Registration Statement is already
effective, after this Agreement becomes effective, the Underwriter proposes to
offer the Firm Shares for sale to the public upon the terms and conditions set
forth in the Prospectus.  The Underwriter may from time to time thereafter
reduce the public offering price and change the other selling terms, provided
the proceeds to the Trust shall not be reduced as a result of such reduction or
change.

                 The Underwriter may reserve and sell such of the Shares
purchased by the Underwriter as the Underwriter may elect to dealers chosen by
it (the "Selected Dealers") at the public offering price set forth in the
Prospectus less the applicable Selected Dealers' concessions set forth therein,
for re-offering by Selected Dealers to the public at the public offering price.
The Underwriter may allow, and Selected Dealers may re-allow, a concession set
forth in the Prospectus to certain other brokers and dealers.

                 4.       CERTAIN COVENANTS OF THE OFFERORS.    The Offerors
jointly and severally covenant with the Underwriter as follows:

                 (a)      The Offerors shall use their best efforts to cause
the Registration Statement and any amendments thereto, if not effective at the
time of execution of this Agreement, to become effective as promptly as
possible.  If the Registration Statement has become or becomes effective
pursuant to Rule 430A and information has been omitted therefrom in reliance on
Rule 430A, then, the Offerors will prepare and file in accordance with Rule
430A and Rule 424(b) copies of the Prospectus or, if required by Rule 430A, a
post-effective amendment to the Registration Statement (including the
Prospectus) containing all information so omitted and will provide evidence
satisfactory to the Underwriter of such timely filing.

                 (b)  The Offerors shall notify you immediately, and confirm
such notice in writing:

                      (i)         when the Registration Statement, or any
         post-effective amendment to the Registration Statement, has become
         effective, or when the Prospectus or any supplement to the Prospectus
         or any amended Prospectus has been filed;

                      (ii)        of the receipt of any comments or requests
         from the Commission;

                    (iii)         of any request of the Commission to amend or
         supplement the Registration Statement, any Preliminary Prospectus or
         the Prospectus or for additional information; and

                      (iv)         of the issuance by the Commission or any
         state or other regulatory body of any stop order or other order
         suspending the effectiveness of the Registration Statement, preventing
         or suspending the use of any Preliminary Prospectus or the Prospectus,
         or suspending the qualification of any of the Shares for offering or
         sale in any jurisdiction or the institution or threat of institution
         of any proceedings for any of such purposes.  The Offerors shall use
         their best efforts to prevent the issuance of any such stop order or
         of any other such order and if any such order is issued, to cause such
         order to be withdrawn or lifted as soon as possible.


                                       18

                 (c)  The Company shall furnish to you, from time to time

request of (i) the registration statement as originally filed and of all
amendments thereto, in executed form, including exhibits, whether filed before

documents incorporated therein or filed therewith, (iii) all consents and
certificates of experts in executed form, (iv) each Preliminary Prospectus and
all amendments and supplements thereto, and (v) the Prospectus, and all
amendments and supplements thereto.

                 (d)      During the time when a prospectus is required to be
delivered under the 1933 Act, the Offerors shall comply to the best of their
ability with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the
1934 Act Regulations so as to permit the completion of the distribution of the
Shares as contemplated herein and in the Prospectus.  The Offerors shall not
file any amendment to the registration statement as originally filed or to the
Registration Statement and shall not file any amendment thereto or make any
amendment or supplement to any Preliminary Prospectus or to the Prospectus of
which you shall not previously have been advised in writing and provided a copy
a reasonable time prior to the proposed filings thereof or to which you shall
reasonably object.  If it is necessary, in your reasonable opinion or in the
reasonable opinion of your counsel to amend or supplement the Registration
Statement or the Prospectus in connection with the distribution of the Shares,
the Offerors shall forthwith amend or supplement the Registration Statement or
the Prospectus, as the case may be, by preparing and filing with the
Commission, and furnishing to you, such number of copies as you may reasonably
request of an amendment or amendments of, or a supplement or supplements to,
the Registration Statement or the Prospectus, as the case may be (in form and
substance reasonably satisfactory to you and your counsel.  If any event shall
occur as a result of which it is necessary to amend or supplement the
Prospectus to correct an untrue statement of a material fact or to include a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, or if for any reason
it is necessary at any time to amend or supplement the Prospectus to comply
with the 1933 Act and the 1933 Act Regulations, the Offerors shall, subject to
the second sentence of this subsection (d), forthwith amend or supplement the
Prospectus by preparing and filing with the Commission, and furnishing to you,
such number of copies as you may reasonably request of an amendment or
amendments of, or a supplement or supplements to, the Prospectus (in form and
substance satisfactory to you and your counsel so that, as so amended or
supplemented, the Prospectus shall not contain an untrue statement of a
material fact or omit to state a material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

                 (e)      The Offerors shall cooperate with you and your
counsel in order to qualify the Shares for offering and sale under the
securities or blue sky laws of such jurisdictions as you may reasonably request
and shall continue such qualifications in effect so long as may be advisable
for distribution of the Shares; provided, however, that the Offerors shall not
be required to qualify to do business as a foreign corporation or file a
general consent to service of process in any jurisdiction in connection with
the foregoing.  The Offerors shall file such statements and reports as may be
required by the laws of each jurisdiction in which the Shares have been
qualified as above.  The Offerors will notify you immediately of, and confirm
in writing, the suspension of qualification of the Shares or threat thereof in
any jurisdiction.

Prospectus under the caption "Use of Proceeds."

shall furnish to the Underwriter copies of all reports and communications
(financial or otherwise) furnished by the Company to the holders of the Shares
as a class, copies of all reports and financial statements filed with or
furnished to the Commission (other than portions for which confidential
treatment has been obtained from the Commission) or with any national
securities exchange or the Nasdaq National Market and such other documents,
reports and information concerning the business and financial condition of the
Company as the Underwriter may reasonably request, other than such documents,
reports and information for which the Company has the legal obligation not to
reveal to the Underwriter.

                 (i)      For a period of 180 days from the date hereof, the
Company shall not, directly or indirectly, offer for sale, sell or agree to
sell or otherwise dispose of any shares of the common stock securities
convertible into, exercisable or exchangeable for, or that are the economic or
voting equivalent of, any such shares of common stock, or announce the offering

Offerors shall not, directly or indirectly, offer for sale, sell or agree to
sell or otherwise dispose of any shares of Shares, any other beneficial

Company that are substantially similar to the Shares, including any guarantee
of any such beneficial interests or substantially similar securities, or
securities convertible into or exchangeable for or that represent the right to
receive any such beneficial interest or substantially similar securities,
without your prior written consent.

                 (k)      The Offerors shall use their best efforts to cause
the Shares to become quoted on the Nasdaq National Market, or in lieu thereof a
national securities exchange, and to remain so quoted for at least five years
from the Effective Date or for such shorter period as may be specified in a
written consent of the Underwriter, provided this shall not prevent the Company
from redeeming the Shares pursuant to the terms of the Certificate of
Designations.  If the Shares are exchanged for Debentures, the Company will use
its best efforts to have the Debentures listed on the exchange or other
organization on which the Preferred securities are then listed, and to have the
Debentures registered under the Exchange Act.

                 (l)      Subsequent to the date of this Agreement and through
the date which is the later of (i) the day following the date on which the
Underwriter's option to purchase the Option Shares shall expire or (ii) the day
following the Option Closing Date with respect to any Option Shares that the
Underwriter shall elect to purchase, except as described in or contemplated by
the Prospectus, neither the Offerors nor the Banks shall take any action (or
refrain from taking any action) which will result in the Offerors or the Banks
incurring any material liability or obligation, direct or contingent, or enter
into any material transaction, except in the ordinary course of business, and
there will not be any material change in the financial position, capital stock,
or any material increase in long-term debt, obligations under capital leases or
short-term borrowings of the Offerors and the Banks on a consolidated basis.

purchase, redeem or call for redemption, or prepay or give notice of prepayment
(or announce any redemption or call for redemption, or any repayment or notice
of prepayment) of any of the Company's securities, provided that the foregoing
shall not prevent an employee from delivering the Company's securities in
payment of the exercise price of options issued under the Company's Incentive
Share Grant Plan and Employee Stock Option Plan.

                 (n)      The Offerors shall not take, directly or indirectly,
any action designed to result in or which has constituted or which might
reasonably be expected to cause or result in stabilization or manipulation of
the price of any security of the Company to facilitate the sale or resale of
the Shares and the Company is not aware of any such action taken or to be taken
by any affiliate of the Company.

                 (o)      Prior to the Closing Date (and, if applicable, the
Option Closing Date), the Offerors will not issue any press release or other
communication directly or indirectly or hold any press conference with respect
to the Company, the Banks or the offering of the Shares (the "Offering")
without your prior written consent which will not be unreasonably withheld.

                 5.       PAYMENT OF EXPENSES.  Whether or not this Agreement

                 (c)      All corporate proceedings and other legal matters
incident to the authorization, form and validity of this Agreement, the
Certificate of Designations, the Trust Agreement, the Shares and the Shares,
and the authorization and form of the Registration Statement and Prospectus,
other than financial statements and other financial data, and all other legal
matters relating to this Agreement and the transactions contemplated hereby or
by the Certificate of Designations shall be satisfactory in all respects to
your counsel, and the Offerors and the Banks shall have furnished to such

the Company, shall have furnished to you their signed opinion, dated the
Closing Date or the Option Closing Date, as the case may be, in form and
substance satisfactory to your counsel, to the effect that:

                      (i)         The Company has been duly incorporated and is
         validly existing and in good standing under the laws of the State of
         Michigan, and is duly registered as a bank holding company under the
         BHC Act.  Each of the Banks is a state banking corporation duly

         Michigan.  Each of the Banks is a member of the Federal Reserve
         System, and to the knowledge of such counsel no proceedings for the
         termination or revocation of such membership are pending or
         threatened.  The deposit accounts of the Banks are insured by the FDIC
         up to the maximum amount provided by law, except to the extent the
         Prospectus discloses such deposit accounts are insured by SAIF and to
         such extent the deposit accounts are so insured up to the maximum
         amount provided by law; and to the knowledge of such counsel no
         proceedings for the termination or revocation of any such insurance or
         such membership are pending or threatened.  Each of the Company and
         the Banks has full corporate power and authority to own or lease its
         properties and to conduct its business as such business is described
         in the Prospectus and is currently conducted in all material respects.
         All outstanding shares of capital stock of the Banks have been duly
         authorized and validly issued and are fully paid and nonassessable
         except to the extent such shares may be deemed assessable under 12
         U.S.C. Section 55 or 12 U.S.C. Section 1831o and, to the best of such
         counsel's knowledge, except as disclosed in the Prospectus, there are
         no outstanding rights, options or warrants to purchase any such shares
         or securities convertible into or exchangeable for any such shares.

                      (ii)        The capital stock of the Company conforms to
         the description thereof contained in the Prospectus in all material
         respects.  The capital stock of the Company authorized to be issued as
         of September 30, 1996 is as set forth under the caption
         "Capitalization" in the Prospectus, has


                                       25
<PAGE>   26


         been duly authorized and validly issued, is fully paid and
         nonassessable.  The form of certificates to evidence the Shares has
         been approved by the Board of Directors and is in due and proper form
         and complies with all applicable requirements.  To the best of such
         counsel's knowledge there are no outstanding rights, options or
         warrants to purchase, no other outstanding securities convertible into
         or exchangeable for, and no commitments, plans or arrangements to
         issue, any shares of capital stock of the Company, except as described
         in the Prospectus.

                    (iii)         All corporate action required to be taken by
         the Company for the authorization, issuance, sale and delivery of the
         Shares in accordance with such terms and conditions has been validly
         and sufficiently taken.  All of the Shares have been duly and validly
         authorized and, when delivered in accordance with this Agreement will
         be duly and validly issued, fully paid and nonassessable, and will
         conform to the description thereof in the Registration Statement, the
         Prospectus and the Certificate of Designations.  The Shares have been
         approved for quotation on the Nasdaq National Market subject to
         official notice of issuance.  There are no preemptive or other rights
         to subscribe for or to purchase, and other than as disclosed in the
         Prospectus no restrictions upon the voting or transfer of, any shares
         of capital stock of the Company or the Banks pursuant to the corporate
         charter (including without limitation, the Certificate of
         Designations), by-laws or other governing documents of the Company or
         the Banks, or, to the best of such counsel's knowledge any agreement
         or other instrument to which the Company or the Banks is a party or by
         which the Company or the Banks may be bound.

                      (iv)        The Company has all requisite corporate power
         to enter into and perform its obligations under this Agreement and the
         Certificate of Designations, and this Agreement and the Certificate of
         Designations have been duly and validly authorized, executed and
         delivered by the Company and constitutes the legal, valid and binding
         obligation of the Company enforceable in accordance with their terms,
         except as the enforcement hereof or thereof may be limited by general
         principles of equity and by bankruptcy or other laws relating to or
         affecting creditors' rights generally, and except as the
         indemnification and contribution provisions hereof may be limited
         under applicable laws and certain remedies may not be available in the
         case of a non-material breach.

                    (v)        Each of the Indenture, the Trust Agreement and
         the Guarantee has been duly qualified under the Trust Indenture Act,
         has been duly authorized, executed and delivered by the Company, and
         is a valid and legally binding obligation of the Company enforceable
         in accordance with its


                                       26
<PAGE>   27


         terms, subject to the effect of bankruptcy, insolvency,
         reorganization, receivership, moratorium and other laws affecting the
         rights and remedies of creditors generally and of general principles
         of equity;

                      (vi)        The Debentures have been duly authorized,
         executed and delivered by the Company, are entitled to the benefits of
         the Indenture and are legal, valid and binding obligations of the
         Company enforceable against the Company in accordance with their
         terms, subject to the effect of bankruptcy, insolvency,
         reorganization, receivership, moratorium and other laws affecting the
         rights and remedies of creditors generally and of general principles
         of equity;

                    (vii)         The Expense Agreement has been duly
         authorized, executed and delivered by the Company, and is a valid and
         legally binding obligation of the Company enforceable in accordance
         with its terms, subject to the effect of bankruptcy, insolvency,
         reorganization, receivership, moratorium and other laws affecting the
         rights and remedies of creditors generally and of general principles
         of equity;

                 (viii)           To the best knowledge of such counsel's
         knowledge neither the Company nor any of the Banks is in breach or
         violation of, or default under, with or without notice or lapse of
         time or both, its corporate charter (including without limitation, the
         Certificate of Designations) or by-laws.  The execution, delivery and
         performance of this Agreement and the consummation of the transactions
         contemplated by this Agreement, and the Certificate of Designations do
         not and will not conflict with, result in the creation or imposition
         of any material lien, claim, charge, encumbrance or restriction upon
         any property or assets of the Company or the Banks or the Shares
         pursuant to, or constitute a material breach or violation of, or
         constitute a material default under, with or without notice or lapse
         of time or both, any of the terms, provisions or conditions of the
         charter (including without limitation, the Certificate of
         Designations) or by-laws of the Company or the Banks, or to the best
         of such counsel's knowledge, any material contract, indenture,
         mortgage, deed of trust, loan or credit agreement, note, lease,
         franchise, license or any other agreement or instrument to which the
         Company the Banks is a party or by which either of them or any of
         their respective properties may be bound or any order, decree,
         judgment, franchise, license, Permit, rule or regulation of any court,
         arbitrator, government, or governmental agency or instrumentality,
         domestic or foreign, known to such counsel having jurisdiction over
         the Company or the Banks or any of their respective properties which,
         in each case, is material to the Company and its subsidiaries on a
         consolidated basis. No authorization, approval, consent or order of,
         or filing, registration or


                                       27
<PAGE>   28


         qualification with, any person (including, without limitation, any
         court, governmental body or authority) is required under Michigan law
         in connection with the transactions contemplated by this Agreement
         except as may be required under Oklahoma securities laws in connection
         with the purchase and distribution of the Shares by the Underwriters.

                      (ix)        To the best of such counsel's knowledge
         holders of securities of the Company either do not have any right
         that, if exercised, would require the Company to cause such securities
         to be included in the Registration Statement or have waived such
         right.  To the best of such counsel's knowledge neither the Company
         nor any of the Banks is a party to any agreement or other instrument
         which grants rights for or relating to the registration of any
         securities of the Company.

                      (x)         Except as set forth in the Registration
         Statement and the Prospectus, to the best of such counsel's knowledge
         no action, suit or proceeding at law or in equity is pending or
         threatened in writing to which the Company or the Banks is or may be a
         party, and no action, suit or proceeding is pending or threatened in
         writing against or affecting the Company or the Banks or any of their
         properties before or by any court or governmental official,
         commission, board or other administrative agency, authority or body,
         or any arbitrator, wherein an unfavorable decision, ruling or finding
         could have a material adverse effect on the consummation of this
         Agreement or the issuance and sale of the Shares as contemplated
         herein or the condition (financial or otherwise), earnings, affairs,
         business, or results of operations of the Company and the Banks on a
         consolidated basis or which is required to be disclosed in the
         Registration Statement or the Prospectus and is not so disclosed.

                      (xi)        No authorization, approval, consent or order
         of or filing, registration or qualification with, any person
         (including, without limitation, any court, governmental body or
         authority) is required in connection with the transactions
         contemplated by this Agreement, the Certificate of Designations, the
         Registration Statement and the Prospectus, except such as have been
         obtained under the 1933 Act, and such as may be required under state
         securities laws or Interpretations or Rules of the NASD in connection
         with the purchase and distribution of the Shares by the Underwriter.

                    (xii)         The Registration Statement and the Prospectus
         and any amendments or supplements thereto (other than the financial
         statements or other financial data included therein or omitted
         therefrom and Underwriter's Information, as to which such counsel need
         express no opinion) comply as


                                       28
<PAGE>   29


         to form in all material respects with the requirements of the 1933 Act
         and the 1933 Act Regulations as of their respective dates of
         effectiveness.

                   (xiii)         To the best of such counsel's knowledge,
         there are no contracts, agreements, leases or other documents of a
         character required to be disclosed in the Registration Statement or
         Prospectus or to be filed as exhibits to the Registration Statement
         that are not so disclosed or filed.

                    (xiv)         The statements under the captions
         "Description of Capital Stock", "Supervision and Regulation",
         "Description of the Preferred Securities", "Description of the
         Subordinated Debentures" and Description of the Guarantee" in the
         Prospectus, insofar as such statements constitute a summary of legal
         and regulatory matters, documents or proceedings referred to therein
         are accurate in all material respects and fairly present the
         information called for with respect to such legal matters, documents
         and proceedings.

                      (xv)        Such counsel has been advised by the staff of
         the Commission that the Registration Statement has become effective
         under the 1933 Act; any required filing of the Prospectus pursuant to
         Rule 424(b) has been made within the time period required by Rule
         424(b); to the best of such counsel's knowledge no stop order
         suspending the effectiveness of the Registration Statement has been
         issued and no proceedings for a stop order are pending or threatened
         by the Commission.

                    (xvi)         Except as set forth in the Prospectus, to the
         best of such counsel's knowledge there are no contractual encumbrances
         or restrictions, or material legal restrictions on the ability of the
         Banks (A) to pay dividends or make any other distributions on its
         capital stock or to pay indebtedness owed to the Company, (B) to make
         any loans or advances to, or investments in, the Company or (C) to
         transfer any of its property or assets to the Company.


                                       29
<PAGE>   30


                   (xvii)         To the best of such counsel's knowledge (A)
         the business and operations of the Company and the Banks comply in all
         material respects with all statutes, ordinances, laws, rules and
         regulations applicable thereto and which are material to the Company
         and the Banks on a consolidated basis, except in those instances where
         non-compliance would not materially impair the ability of the Company
         and the Banks to conduct their business; and (B)  the Company and the
         Banks possess and are operating in all material respects in compliance
         with the terms, provisions and conditions of all permits, consents,
         licenses, franchises and governmental and regulatory authorizations
         ("Permits") and required to conduct their businesses as described in
         the Prospectus and which are material to the Company and the Banks on
         a consolidated basis, except in those instances where the loss thereof
         or non-compliance therewith would not have a material adverse effect
         on the condition (financial or otherwise), earnings, affairs,
         business, prospects or results of operations of the Company and the
         Banks on a consolidated basis; to the best of such counsel's knowledge
         all such Permits are valid and in full force and effect, and to the
         best of such counsel's knowledge no action, suit or proceeding is
         pending or threatened which may lead to the revocation, termination,
         suspension or non-renewal of any such Permit, except in those
         instances where the loss thereof or non-compliance therewith would not
         materially impair the ability of the Company or the Banks to conduct
         their businesses.

                 In giving the above opinion, such counsel may state that,
insofar as such opinion involves factual matters, they have relied upon
certificates of officers of the Company including, without limitation,
certificates as to the identity of any and all material contracts, indentures,
mortgages, deeds of trust, loans or credit agreements, notes, leases,
franchises, licenses or other agreements or instruments, and all material
permits, easements, consents, licenses, franchises and government regulatory
authorizations, for purposes of paragraphs (vii), (xii) and (xvi) hereof and
certificates of public officials.

                 Such counsel shall also confirm that, in connection with the
preparation of the Registration Statement and Prospectus, such counsel has
participated in conferences with officers and representatives of the Company
and with its independent public accountants and with you and your counsel, at
which conferences such counsel made inquiries of such officers, representatives
and accountants and discussed in detail the contents of the Registration
Statement and Prospectus and such counsel has no reason to believe (A) that the
Registration Statement or any amendment thereto (except for the financial
statements included therein or omitted therefrom Underwriter's Information, as
to which such counsel need express no opinion), at the time the Registration
Statement or any such amendment became effective, contained any untrue
statement of a material fact or


                                       30
<PAGE>   31


omitted to state any material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances in which they
were made, not misleading or (B) that the Prospectus or any amendment or
supplement thereto (except for the financial statements included therein or
omitted therefrom Underwriter's Information, as to which such counsel need
express no opinion), at the time the Registration Statement became effective
(or, if the term "Prospectus" refers to the prospectus first filed pursuant to
Rule 424(b) of the 1933 Act Regulations, at the time the Prospectus was
issued), at the time any such amended or supplemented Prospectus was issued, at
the Closing Date and, if applicable, the Option Closing Date, contained or
contains any untrue statement of a material fact or omitted or omits to state
any material fact required to be stated therein or necessary to make the
statements therein, not misleading or (C) that there is any amendment to the
Registration Statement required to be filed that has not already been filed.

                 (f)      On the Date of Delivery, you shall have received the
opinion of Richards, Layton and Finger, special Delaware counsel to the
Offerors, dated as of such date, to the effect that:

                 (i)      The Trust has been duly created and is validly
                 existing in good standing as a business trust under the
                 Delaware Business Trust Act and, under the Trust Agreement and
                 the Delaware Business Trust Act, has the trust power and
                 authority to conduct its business as described in the
                 Prospectus.

                 (ii)     The Trust Agreement is a legal, valid and binding
                 agreement of the Company and the Trustees, and is enforceable
                 against the Company and the Trustees, in accordance with its
                 terms.

                 (iii)    Under the Trust Agreement and the Delaware Business
                 Trust Act, the execution and delivery of the Underwriting
                 Agreement by the Trust, and the performance by the Trust of
                 its obligations thereunder, have been authorized by all
                 requisite trust action on the part of the Trust.

                 (iv)     The Shares have been duly authorized by the Trust
                 Agreement, and when issued and sold in accordance with the
                 Trust Agreement, the Shares will be, subject to the
                 qualifications set forth in paragraph (v) below, fully paid
                 and nonassessable beneficial interest in the assets of the
                 Trust and entitled to the benefits of the Trust Agreement.

                 (v)      The Preferred Security holders, as beneficial owners
                 of the Trust, will be entitled to the same limitation of
                 personal liability


                                       31

                 extended to stockholders of private for profit corporations
                 organized under the General Corporation Law of the State of
                 Delaware.  Such opinion may not that the Preferred Security
                 Holders may be obligated to make payments as set forth in the
                 Trust Agreement.

                 (vi)     Under the Delaware Business Trust Act and the Trust
                 Agreement, the issuance of the Shares is not subject to
                 preemptive rights.

                 (vii)    The issuance and sale by the Trust of the Shares, the
                 execution, delivery and performance by the Trust of this
                 Agreement, and the consummation of the transactions
                 contemplated by this Agreement, do not violate (a) the Trust
                 Agreement, or (b) any applicable Delaware law, rule or
                 regulation.

         Such opinion may state that it is limited to the laws of the State of
Delaware and that the opinion expressed in paragraph (ii) above is subject to
the effect upon the Trust Agreement of (i) bankruptcy, insolvency, moratorium,
receivership, reorganization, liquidation, fraudulent conveyance and other
similar laws relating to or affecting the rights and remedies of creditors
generally, (ii) principles of equity, including applicable law relating to
fiduciary duties (regardless of whether considered and applied in a proceeding
in equity or at law), and (iii) the effect of applicable public policy on the
enforceability of provisions relating to indemnification or contribution.

                 (g)      Bryan Cave LLP, counsel for the Underwriter, shall
have furnished you their signed opinion, dated the Closing Date or the Option
Closing Date, as the case may be, with respect to the incorporation of the
Company, the validity of the Shares, the Registration Statement, the Prospectus
and such other related matters as you may reasonably request and there shall
have been furnished to such counsel such documents and other information as
they may request to enable them to pass on such matters.  In giving such
opinion, Bryan Cave LLP may rely as to matters of fact upon statements and
certifications of officers of the Company and of other appropriate persons and
may rely as to matters of law, other than law of the United States and the
State of Missouri, and upon the opinion of Varnum, Riddering Schmidt & Howlett
LLP described herein.

                 (h)  On the date of this Agreement and on the Closing Date
(and, if applicable, any Option Closing Date), the Underwriter shall have
received from KPMG Peat Marwick LLP a letter, dated the date of this Agreement
and the Closing Date (and, if applicable, the Option Closing Date),
respectively, in form and substance satisfactory to the Underwriter, confirming
that they are independent


                                       32

public accountants with respect to the Company and the Banks, within the
meaning of the 1933 Act and the 1933 Act Regulations, and stating in effect
that:

                      (i)         In their opinion, the consolidated financial
         statements of the Company and the Banks audited by them and included
         in the Registration Statement comply as to form in all material
         respects with the applicable accounting requirements of the 1933 Act
         and the 1933 Act Regulations.

                      (ii)         On the basis of the procedures specified by
         the American Institute of Certified Public Accountants as described in
         SAS No. 71, "Interim Financial Information", inquiries of officials of
         the Company and the Banks responsible for financial and accounting
         matters, and such other inquiries and procedures as may be specified
         in such letter, which procedures do not constitute an audit in
         accordance with U.S. generally accepted auditing standards, nothing
         came to their attention that caused them to believe that, if
         applicable, the unaudited interim consolidated financial statements of
         the Company and the Banks included in the Registration Statement do
         not comply as to form in all material respects with the applicable
         accounting requirements of the 1933 Act and 1933 Act Regulations or
         are not in conformity with U.S. generally accepted accounting
         principles applied on a basis substantially consistent with the basis
         for the audited consolidated financial statements of the Company and
         the Banks included in the Registration Statement.

                    (iii)         On the basis of limited procedures, not
         constituting an audit in accordance with U.S. generally accepted
         auditing standards, consisting of a reading of the unaudited interim
         financial statements and other information referred to below, a
         reading of the latest available unaudited condensed consolidated
         financial statements of the Company and the Banks, inspection of the
         minute books of the Company and the Banks since the date of the latest
         audited financial statements of the Company and the Banks included in
         the Registration Statement, inquiries of officials of the Company and
         the Banks responsible for financial and accounting matters and such
         other inquiries and procedures as may be specified in such letter,
         nothing came to their attention that caused them to believe that:

                          (A)     as of a specified date not more than five
                 days prior to the date of such letter, there have been any
                 changes in the consolidated capital stock, allowance for loan
                 losses, or net loans receivable of the Company and the Banks,
                 any increase in the consolidated long-term debt, short-term
                 borrowings, obligations under capital leases or real estate
                 owned by the Company and the Banks, any decreases in
                 consolidated total assets or shareholders equity of the
                 Company and


                                       33

                 the Banks, or any changes, decreases or increases in other
                 items specified by the Underwriter, in each case as compared
                 with amounts shown in the latest unaudited interim
                 consolidated statement of financial condition of the Company
                 and the Banks included in the Registration Statement except
                 in each case for changes, increases or decreases which the
                 Registration Statement specifically discloses, have occurred
                 or may occur or which are described in such letter; and

                          (B)     for the period from the date of the latest
                 unaudited interim consolidated financial statements included
                 in the Registration Statement to the specified date referred
                 to in Clause (iii)(A), there were any decreases in the
                 consolidated interest income, net interest income, other
                 operating income or net income of the Company and the Banks or
                 in the per share amount of net income of the Company and the
                 Banks any increase in consolidated other operating expense of
                 the Company and the Banks, or any changes, decreases or
                 increases in any other items specified by the Underwriter, in
                 each case as compared with the comparable period of the
                 preceding year and with any other period of corresponding
                 length specified by the Underwriter, except in each case for
                 increases or decreases which the Registration Statement
                 discloses have occurred or may occur, or which are described
                 in such letter.

                    (iv)        In addition to the audit referred to in their
         report included in the Registration Statement and the limited
         procedures, inspection of minute books, inquiries and other procedures
         referred to in paragraphs (ii) and (iii) above, they have carried out
         certain specified procedures, not constituting an audit in accordance
         with U.S. generally accepted auditing standards, with respect to
         certain amounts, percentages and financial information specified by
         the Underwriter which are derived from the general accounting records
         and consolidated financial statements of the Company and the Banks
         which appear in the Registration Statement specified by the
         Underwriter in the Registration Statement, and have compared such
         amounts, percentages and financial information with the accounting
         records and the material derived from such records and consolidated
         financial statements of the Company and the Banks have found them to
         be in agreement.

                 In the event that the letters to be delivered referred to
above set forth any such changes, decreases or increases as specified in
Clauses (iii)(A) or (iii)(B) above, or any exceptions from such agreement
specified in Clause (iv) above, it shall be a further condition to the
obligations of the Underwriter that the Underwriter shall have determined,
after discussions with officers of the Company

                                       34
<PAGE>   35


responsible for financial and accounting matters, that such changes, decreases,
increases or exceptions as are set forth in such letters do not (x) reflect a
material adverse change in the items specified in Clause (iii)(A) above as
compared with the amounts shown in the latest unaudited consolidated statement
of financial condition of the Company and the Banks included in the
Registration Statement, (y) reflect a material adverse change in the items
specified in Clause (iii)(B) above as compared with the corresponding periods
of the prior year or other period specified by the Underwriter, or (z) reflect
a material change in items specified in Clause (iv) above from the amounts
shown in the Preliminary Prospectus distributed by the Underwriter in
connection with the offering contemplated hereby or from the amounts shown in
the Prospectus.

                 (i)      At the Closing Date and, if applicable, the Option
Closing Date, you shall have received certificates of the chief executive
officer and the chief financial and accounting officer of the Company, which
certificates shall be deemed to be made on behalf of the Company dated as of
the Closing Date and, if applicable, the Option Closing Date, evidencing
satisfaction of the conditions of Section 6(a) and stating that (i) the
representations and warranties of the Company set forth in Section 2(a) hereof
are accurate as of the Closing Date and, if applicable, the Option Closing
Date, and that the Offerors have complied with all agreements and satisfied all
conditions on their part to be performed or satisfied at or prior to such
Closing Date; (ii) since the respective dates as of which information is given
in the Registration Statement and the Prospectus, there has not been any
material adverse change in the condition (financial or otherwise), earnings,
affairs, business, prospects or results of operations of the Offerors and the
Banks on a consolidated basis; (iii) since such dates there has not been any
material transaction entered into by the Offerors or the Banks other than
transactions in the ordinary course of business; and (iv) they have carefully
examined the Registration Statement and the Prospectus as amended or
supplemented and nothing has come to their attention that would lead them to
believe that either the Registration Statement or the Prospectus, or any
amendment or supplement thereto as of their respective effective or issue
dates, contained, and the Prospectus as amended or supplemented at such Closing
Date (and, if applicable, the Option Closing Date), contains any untrue
statement of a material fact, or omits to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading; and (v)
covering such other matters as you may reasonably request.  The officer's
certificate of the Company shall further state that no stop order affecting the
Registration Statement is in effect or, to their knowledge, threatened.

                 (j)      You shall have received a certificate, dated the
Closing Date, of an authorized representative of the Trust to the effect that
to the best of his or her knowledge based upon a reasonable investigation, the
representations and


                                       35
<PAGE>   36


warranties of the Trust in this Agreement are true and correct as though made
on and as of the Closing Date; the Trust has complied with all the agreements
and satisfied all the conditions required by this Agreement to be performed or
satisfied by the Trust on or prior to the Closing Date and since the most
recent date as of which information is given in the Prospectus, except as
contemplated by the Prospectus, the Trust has not incurred any material
liabilities or obligations, direct or contingent, or entered into any material
transactions not in the ordinary course of business and there has not been any
material adverse change in the condition (financial or otherwise) of the Trust.

                 (k)      On the Closing Date, you shall have received duly
executed counterparts of the Trust Agreement, the Guarantee, the Indenture and
the Expense Agreement.

                 (l)      The NASD, upon review of the terms of the public
offering of the Shares, shall not have objected to the Underwriter's
participation in such offering.  The Federal Reserve, upon review of the terms
of the public offering of the shares, shall not have objected to the
Underwriter's participation in such offering.

                 (m)      Prior to the Closing Date and, if applicable, the
Option Closing Date, the Company shall have furnished to you and your counsel
all such other documents, certificates and opinions as they have reasonably
requested.

                 All opinions, certificates, letters and other documents shall
be in compliance with the provisions hereof only if they are reasonably
satisfactory in form and substance to you.  The Offerors shall furnish you with
conformed copies of such opinions, certificates, letters and other documents as
you shall reasonably request.

                 If any of the conditions referred to in this Section 6 shall
not have been fulfilled when and as required by this Agreement, this Agreement
and all of your obligations hereunder may be terminated by you on notice to the
Company at, or at any time before, the Closing Date or the Option Closing Date,
as applicable.  Any such termination shall be without liability of the
Underwriter to the Company.

                 7.       INDEMNIFICATION AND CONTRIBUTION.

                 (a)      The Offerors agree to jointly and severally indemnify
and hold harmless the Underwriter, each of its directors, officers and agents,
and each person, if any, who controls the Underwriter within the meaning of the
1933 Act, against any and all losses, claims, damages, liabilities and expenses
(including reasonable costs of investigation and reasonable attorney fees and
expenses), joint or several, arising out of or based (i) upon any untrue
statement or alleged untrue statement of a material fact made by the Company or
the Trust contained in Section 2(a) of this Agreement (or any certificate
delivered by the Company or the Trust pursuant hereto Section 6(l) hereto) or
the registration statement as originally filed or the Registration Statement,
any Preliminary Prospectus or the Prospectus, or in any amendment or supplement
thereto, (ii) upon any blue sky application or other document executed by the
Company or the Trust specifically for that purpose or based upon written
information furnished by the Company or the Trust filed in any state or other
jurisdiction in order to qualify any of the Shares under the securities laws
thereof (any such application, document or information being hereinafter
referred to as a "Blue Sky Application"), (iii) any omission or alleged
omission to state a material fact in the registration statement as originally
filed or the Registration Statement, any Preliminary Prospectus or the
Prospectus, or in any amendment or supplement thereto, or in any Blue Sky
Application) required to be stated therein or necessary to make the statements
therein not misleading, and against any and all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation and
attorney fees), joint or several, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus or the Prospectus, or in any amendment of supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading or (iv) the enforcement of this indemnification
provision or the contribution provisions of Section 7(e); and shall reimburse
each such indemnified party for any reasonable legal or other expenses as
incurred, but in no event less frequently than 30 days after each invoice is
submitted, incurred by them in connection with investigating or defending
against or appearing as a third-party witness in connection with any such loss,
claim, damage, liability or action, notwithstanding the possibility that
payments for such expenses might later be held to be improper, in which case
such payments shall be promptly refunded; provided, however, that the Offerors
shall not be liable in any such case to the extent, but only to the extent,
that any such losses, claims, damages, liabilities and expenses arise out of or
are based upon any untrue statement or omission or allegation thereof that has
been made therein or omitted therefrom in reliance upon and in conformity with
information furnished in writing to the Offerors through you by expressly for
use therein beneath the heading "Underwriting;" provided, that the


                                       37
<PAGE>   38


indemnification contained in this paragraph with respect to any Preliminary
Prospectus shall not inure to the benefit of the Underwriter (or of any person
controlling the Underwriter) to the extent any such losses, claims, damages,
liabilities or expenses directly results from the fact that such Underwriter
sold Shares to a person to whom there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the Prospectus (as amended or
supplemented if any amendments or supplements thereto shall have been furnished
to the Underwriter in sufficient time to distribute same with or prior to the
written confirmation of the sale involved), if required by law, and if such
loss, claim, damage, liability or expense would not have arisen but for the
failure to give or send such person such document.  The foregoing indemnity
agreement is in addition to any liability the Company or the Trust may
otherwise have to any such indemnified party.

                 (b)      The Underwriter, agrees to indemnify and hold
harmless each Offeror, each of its directors, each of its officers who signed
the Registration Statement and each person, if any, who controls an Offeror
within the meaning of the 1933 Act, to the same extent as required by the
foregoing indemnity from the Company to the Underwriter, but only with respect
to information relating to such Underwriter furnished in writing to an Offeror
through you by or on behalf of it expressly for use in connection with the
registration statement as originally filed, the Registration Statement, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto,
beneath the heading "Underwriting" or in a Blue Sky Application.  The foregoing
indemnity agreement is in addition to any liability which the Underwriter may
otherwise have to any such indemnified party.



                                       38
<PAGE>   39


                 (c)      If any action or claim shall be brought or asserted
against any indemnified party or any person controlling an indemnified party in
respect of which indemnity may be sought from the indemnifying party, such
indemnified party or controlling person shall promptly notify the indemnifying
party in writing, and the indemnifying party shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to the indemnified
party and the payment of all expenses; provided, however, that the failure so
to notify the indemnifying party shall not relieve it from any liability which
it may have to an indemnified party otherwise than under such paragraph, and
further, shall only relieve it from liability under such paragraph to the
extent prejudiced thereby.  Any indemnified party or any such controlling
person shall have the right to employ separate counsel in any such action and
to participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of such indemnified party or such controlling
person unless (i) the employment thereof has been specifically authorized by
the indemnifying party in writing, (ii) the indemnifying party has failed to
assume the defense or to employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both such indemnified party or such controlling
person and the indemnifying party and such indemnified party or such
controlling person shall have been advised by such counsel that there may be
one or more legal defenses available to it that are different from or in
addition to those available to the indemnifying party (in which case, if such
indemnified party or controlling person notifies the indemnifying party in
writing that it elects to employ separate counsel at the expense of the
indemnifying party, the indemnifying party shall not have the right to assume
the defense of such action on behalf of such indemnified party or such
controlling person) it being understood, however, that the indemnifying party
shall not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys at any time and for all
such indemnified party and controlling persons, which firm shall be designated
in writing by the indemnified party.  Each indemnified party and each
controlling person, as a condition of such indemnity, shall use reasonable
efforts to cooperate with the indemnifying party in the defense of any such
action or claim.  The indemnifying party shall not be liable for any settlement
of any such action effected without its written consent, but if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party and any such
controlling person from and against any loss, claim, damage, liability or
expense by reason of such settlement or judgment.


                                       39
<PAGE>   40


                 An indemnifying party shall not, without the prior written
consent of each indemnified party, settle, compromise or consent to the entry
of any judgment in any pending or threatened claim, action, suit or proceeding
in respect of which indemnity may be sought hereunder (whether or not such
indemnified party or any person who controls such indemnified party within the
meaning of the 1933 Act is a party to such claim, action, suit or proceeding),
unless such settlement, compromise or consent includes a release of each such
indemnified party reasonably satisfactory to each such indemnified party and
each such controlling person from all liability arising out of such claim,
action, suit or proceeding or unless the indemnifying party shall confirm in a
written agreement with each indemnified party, that notwithstanding any
federal, state or common law, such settlement, compromise or consent shall not
alter the right of any indemnified party or controlling person to
indemnification or contribution as provided in this Agreement.


                                       40
<PAGE>   41


                 (d)      If the indemnification provided for in this Section 7
is unavailable or insufficient to hold harmless an indemnified party under
paragraphs (a), (b) or (c) hereof in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then each indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages, liabilities or expenses (i) in such proportion as is appropriate to
reflect the relative benefits received by the Offerors on the one hand and the
Underwriter on the other from the offering of the Shares or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Offerors on
the one hand and the Underwriter on the other in connection with the statements
or omissions that resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations.  The relative
benefits received by the Offerors on the one hand and the Underwriter on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering of the Shares (before deducting expenses) received by the
Offerors bear to the total underwriting discounts and commissions received by
the Underwriter, in each case as set forth in the table on the cover page of
the Prospectus.  The relative fault of the Offerors on the one hand and of the
Underwriter on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or
the omission or alleged omission to state a material fact relates to
information supplied by the Offerors or by the Underwriter and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission.  Each Offeror and the Underwriter
agrees that it would not be just and equitable if contribution pursuant to this
paragraph (d) were determined by pro rata allocation or by any other method of
allocation that does not take into account the equitable considerations
referred to herein.  The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities and expenses referred to in
the first sentence of this paragraph (d) shall be deemed to include, subject to
the limitations set forth above, any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or
defending any such action or claim.  Notwithstanding the provisions of this
paragraph (d), the Underwriter shall not be required to contribute any amount
in excess of the amount by which the total price at which the Shares
underwritten by such Underwriter and distributed to the public were offered to
the public exceeds the amount of any damages that such Underwriter has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall
be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.


                                       41
<PAGE>   42


                 For purposes of this paragraph (d), each person who controls
the Underwriter within the meaning of the 1933 Act shall have the same rights
to contribution as such Underwriter, and each person who controls an Offeror
within the meaning of the 1933 Act, each officer of an Offeror who shall have
signed the Registration Statement and each director of an Offeror shall have
the same rights to contribution as the Offerors subject in each case to the
preceding sentence.  The obligations of the Offerors under this paragraph (d)
shall be in addition to any liability which the Offerors may otherwise have and
the obligations of the Underwriter under this paragraph (d) shall be in
addition to any liability that the Underwriter may otherwise have.

                 (e)      The indemnity and contribution agreements contained
in this Section 7 and the representations and warranties of the Offerors set
forth in this Agreement shall remain operative and in full force and effect,
regardless of (i) any investigation made by or on behalf of the Underwriter or
any person controlling the Underwriter or by or on behalf of the Company, or
such directors or officers (or any person controlling and Offeror, (ii)
acceptance of any Shares and payment therefor hereunder and (iii) any
termination of this Agreement.  A successor of the Underwriter or of and
Offeror, such directors or officers (or of any person controlling the
Underwriter or an Offeror) shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

                 (f)      The Company agrees to indemnify the Trust against any
and all losses, claims, damages or liabilities that may become due from the
Trust under this Section 7.

                 8.       TERMINATION.  You shall have the right to terminate
this Agreement at any time at or prior to the Closing Date or, with respect to
your obligation to purchase the Option Shares, at any time at or prior to the
Option Closing Date, without liability on the part of the Underwriter to the
Offerors, if:

                 (a)  Either Offeror shall have failed, refused, or been unable
to perform any agreement on its part to be performed under this Agreement, or
any of the conditions referred to in Section 6 shall not have been fulfilled,
when and as required by this Agreement;

                 (b)      The Offerors or the Banks shall have sustained any
material loss or interference with its business from fire, explosion, flood or
other calamity, whether or not covered by insurance, or from any labor dispute
or court or governmental action, order or decree which in the judgment of the
Underwriter materially impairs the investment quality of the Shares;


                                       42
<PAGE>   43


                 (c)      There has been since the respective dates as of which
information is given in the Registration Statement or the Prospectus, any
materially adverse change in, or any development which is reasonably likely to
have a material adverse effect on, the condition (financial or otherwise),
earnings, affairs, business, prospects or results of operations of the Company
and the Banks on a consolidated basis, whether or not arising in the ordinary
course of business;

                 (d)      There has occurred any outbreak of hostilities or
other calamity or crisis or material change in general economic, political or
financial conditions, or internal conditions, the effect of which on the
financial markets of the United States is such as to make it, in your
reasonable judgment, impracticable to market the Shares or enforce contracts
for the sale of the Shares;

                 (e)      Trading generally on the New York Stock Exchange, the
American Stock Exchange or the Nasdaq National Market shall have been
suspended, or minimum or maximum prices for trading shall have been fixed, or
maximum ranges for prices for securities shall have been required, by any of
said exchanges or market system or by the Commission or any other governmental
authority;

                 (f)      A banking moratorium shall have been declared by
either federal or Michigan authorities; or

                 (g)      Any action shall have been taken by any government in
respect of its monetary affairs which, in your reasonable judgment, has a
material adverse effect on the United States securities markets.

                 If this Agreement shall be terminated pursuant to this Section
8, the Offerors shall not then be under any liability to the Underwriter except
as provided in Sections 5 and 7 hereof.

                 10.      EFFECTIVE DATE OF AGREEMENT.  If the Registration
Statement is not effective at the time of execution of this Agreement, this
Agreement shall become effective on the Effective Date at the time the
Commission declares the Registration Statement effective.  The Company shall
immediately notify the Underwriter when the Registration Statement becomes

                 If the Registration Statement is effective at the time of
execution of this Agreement, this Agreement shall become effective at the
earlier of 11:00 a.m. St. Louis time, on the first full business day following
the day on which this Agreement is executed, or at such earlier time as the
Underwriter shall release the Shares for initial public offering.  The

it may be terminated by the Offerors, by notifying you, or by you by notifying
either Offerors, except that the provisions of Sections 5 and 7 shall at all
times be effective.

                 11.      REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE

statements of the Offerors and their officers set forth in or made pursuant to

                 having an aggregate principal amount equal to the aggregate
                 liquidation amount of the Non Book-Entry Preferred Securities

                 the Preferred Security Certificate canceled, will be executed
                 by the Company and delivered to the Trustee for authentication
                 and delivery in accordance with this Indenture.  On issue of
                 such Debentures, Debentures with an equivalent aggregate
                 principal amount that were presented by the Property Trustee
                 to the Trustee will be deemed to have been canceled.

                 (b)      A Global Debenture may be transferred, in whole but
         not in part, only to another nominee of the Depositary, or to a
         successor Depositary selected or approved by the Company or to a
         nominee of such successor Depositary.

         that it is unwilling or unable to continue as Depositary or if at any
         time the Depositary for such series shall no longer be registered or
         in good standing under the Securities Exchange Act of 1934, as
         amended, or other applicable statute or regulation, and a successor
         Depositary for such series is not appointed by the Company within 90
         days after the Company receives such notice or becomes aware of such
         condition, as the case may be, the Company will execute, and the
         Trustee, upon written notice from the Company, will authenticate and
         deliver the Debentures in definitive registered form without coupons,
         in authorized denominations, and in an aggregate principal amount
         equal to the principal amount of the Global Debenture in exchange for
         such Global Debenture.  In addition, the Company may at any time
         determine that the Debentures shall no longer be represented by a
         Global Debenture.  In such event the Company will execute, and the
         Trustee, upon receipt of an Officers Certificate evidencing such
         determination by the Company, will authenticate and deliver the
         Debentures in definitive registered form without coupons, in
         authorized denominations, and in an aggregate principal amount equal
         to the principal amount of the Global Debenture in exchange for such
         Global Debenture.  Upon the exchange of the Global Debenture for such
         Debentures in definitive registered form without coupons, in
         authorized denominations, the Global Debenture shall be canceled by
         the Trustee.  Such Debentures in definitive registered form issued in
         exchange for the Global Debenture shall be registered in such names
         and in such authorized denominations as the Depositary, pursuant to
         instructions from its direct or indirect participants or otherwise,
         shall instruct the Trustee.  The Trustee shall deliver such 
         Securities to the Depositary for delivery to the Persons in whose 
         names such Securities are so registered.

         enforceable under applicable law) on any overdue installment of
         interest at the Coupon Rate, compounded quarterly, payable (subject to
         the provisions of Article Four) quarterly in arrears on March 31, June
         30, September 30 and December 31 of each year (each, an "Interest
         Payment Date," commencing on __________, 1997), to the Person in whose
         name such Debenture or any predecessor Debenture is registered, at the
         close of business on the





                                       11
<PAGE>   17

         regular record date for such interest installment, which, in
         respect of (i) Debentures of which the Property Trustee is the Holder
         and the Preferred Securities are in book-entry only form or (ii) a
         Global Debenture, shall be the close of business on the Business Day
         next preceding that Interest Payment Date.  Notwithstanding the
         foregoing sentence, if (i) the Debentures are held by the Institutional
         Trustee and the Preferred Securities are no longer in book-entry only
         form or (ii) the Debentures are not represented by a Global Debenture,
         the Company may select a regular record date for such interest
         installment which shall be any date at least one Business Day before an
         Interest Payment Date.


                 (b)      The amount of interest payable for any period will be
         computed on the basis of a 360-day year of twelve 30-day months.
         Except as provided in the following sentence, the amount of interest
         payable for any period shorter than a full quarterly period for which
         interest is computed, will be computed on the basis of the actual
         number of days elapsed in such a 30-day period. In the event that any
         date on which interest is payable on the Debentures is not a Business
         Day, then payment of interest payable on such date will be made on the
         next succeeding day which is a Business Day (and without any interest
         or other payment in respect of any such delay), except that, if such
         Business Day is in the next succeeding calendar year, such payment
         shall be made on the immediately preceding Business Day, in each case
         with the same force and effect as if made on such date.

                 (c)      If, at any time while the Property Trustee is the
         Holder of any Debentures, the Trust or the Property Trustee is
         required to pay any taxes, duties, assessments or governmental charges
         of whatever nature (other than withholding taxes) imposed by the
         United States, or any other taxing authority, then, in any case, the
         Company will pay as additional interest ("Additional Interest") on the
         Debentures held by the Property Trustee, such additional amounts as
         shall be required so that the net amounts received and retained by the
         Trust and the Property Trustee after paying such taxes, duties,
         assessments or other governmental charges will be equal to the amounts
         the Trust and the Property Trustee would have received had no such
         taxes, duties, assessments or other government charges been imposed.


                                  ARTICLE III.

SECTION 3.2.     SPECIAL EVENT REDEMPTION.

         Subject to the Company having received the prior approval of the
Federal Reserve, if then required under the applicable capital guidelines or
policies of the Federal Reserve, if a Special Event has occurred and is
continuing,  then, notwithstanding Section 3.3(a) but subject to Section
3.3(b), the Company shall have the right upon not less than 30 days nor more
than 60 days notice to the Holders of the Debentures to redeem the Debentures,
in whole but not in part, for cash within 90 days following the occurrence of
such Special Event (the "90-Day Period") at a redemption price equal to 100% of
the principal amount to be redeemed plus any accrued and unpaid interest
thereon to the date of such redemption (the "Redemption Price"), provided that
if at the time there is available to the Company the opportunity to eliminate,
within the 90-Day Period, the Tax Event by taking some ministerial action
("Ministerial Action"), such as filing a form or making an election, or
pursuing some other similar reasonable measure which has no adverse effect on
the Company, the Trust or the Holders of the Trust Securities issued by the
Trust, the Company shall pursue such Ministerial Action in lieu of redemption,
and, provided, further, that the Company shall have no right to redeem the
Debentures while the Trust is pursuing any Ministerial Action pursuant to its
obligations under the Declaration.  The Redemption Price shall be paid prior to
12:00 noon, New York time, on the date of such redemption or such earlier time
as the Company determines, provided that the Company shall deposit with the
Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., New
York time, on the date such Redemption Price is to be paid.

SECTION 3.3.     OPTIONAL REDEMPTION BY COMPANY.

                 (a)      Subject to the provisions of Section 3.3(b), except
         as otherwise may be specified in this Indenture, the Company shall
         have the right to redeem the Debentures, in whole or in part, from
         time to time, on or after _________, 2001, at a redemption price equal
         to 100% of the principal amount to be redeemed plus any accrued and
         unpaid interest thereon to the date of such redemption (the "Optional
         Redemption Price").  Any redemption pursuant to this paragraph will be
         made upon not less than 30 days nor more than 60 days notice to the
         Holder of the Debentures, at the Optional Redemption Price.  If the
         Debentures are only partially redeemed pursuant to this Section 3.3,
         the Debentures will be redeemed pro rata or by lot or by any other
         method utilized by the Trustee; provided, that if at the time of
         redemption the Debentures are registered as a Global Debenture, the
         Depositary shall determine, in accordance with its procedures, the
         principal amount of such Debentures held by each Holder of Debenture
         to be redeemed.  The Optional Redemption Price shall be paid prior to
         12:00 noon, New York time, on the date of such redemption or at such
         earlier time as the Company determines provided that the Company shall
         deposit with the Trustee an amount sufficient to pay the Optional
         Redemption Price by 10:00 a.m., New York time, on the date such
         Optional Redemption Price is to be paid.

                 (b)      If a partial redemption of the Debentures would
         result in the delisting of the Preferred Securities issued by the
         Trust from The Nasdaq National Market or any national securities
         exchange or other organization on which the Preferred Securities are
         then listed, the Company shall not be permitted to effect such partial
         redemption and may only redeem the Debentures in whole.

SECTION 3.4.     NOTICE OF REDEMPTION.

                 (a)      In case the Company shall desire to exercise such
         right to redeem all or, as the case may be, a portion of the
         Debentures of any series in accordance with the right reserved so to
         do, the Company shall, or shall cause the Trustee to, give notice of
         such redemption to holders of the Debentures of such series to be
         redeemed by mailing, first class postage prepaid, a notice of such
         redemption not less than 30 days and not more than 60 days before the
         date fixed for redemption of that series to such holders at their last
         addresses as they shall appear upon the Security Register unless a
         shorter period is specified in the Debentures to be redeemed.  Any
         notice that is mailed in the manner herein provided shall be
         conclusively presumed to have been duly given, whether or not the
         registered holder receives the notice In any case, failure duly to
         give such notice to the holder of any Security of any series
         designated for redemption in whole or in part, or any defect in the
         notice, shall not affect the validity of the proceedings for the
         redemption of any other Debentures of such series or any other series.
         In the case of any redemption of Debentures prior to the expiration of
         any restriction on such redemption provided in the terms of such
         Debentures or elsewhere in this Indenture, the Company shall furnish
         the Trustee with an Officers' Certificate evidencing compliance with
         any such restriction.

                 Each such notice of redemption shall specify the date fixed
         for redemption and the redemption price at which Debentures of that
         series are to be redeemed, and shall state that payment of the
         redemption price of such Debentures to be redeemed will be made at the
         office or agency of the Company in the Borough of Manhattan, the City
         and State of New York, upon presentation and surrender of such
         Debentures, that interest accrued to the date fixed for redemption
         will be paid as specified in said notice, that from and after said
         date interest will cease to accrue and that the redemption is for a
         sinking fund, if such is the case.  If less than all the Debentures of
         a series are to be redeemed, the notice to the holders of Debentures
         of that series to be redeemed in whole or in part shall specify the
         particular Debentures to be so redeemed.  In case any Security is to
         be redeemed in part only, the notice that relates to such Security
         shall state the portion of the principal amount thereof to be
         redeemed, and shall state that on and after the redemption date, upon
         surrender of such Security, a new Security or Debentures of such
         series in principal amount equal to the unredeemed portion thereof.

                 (b)      If less than all the Debentures of a series are to be
         redeemed, the Company shall give the Trustee at least 45 days' notice
         in advance of the date fixed for redemption as to the aggregate
         principal amount of Debentures of the series to be redeemed, and
         thereupon the Trustee shall select, by lot or in such other manner as
         it shall deem appropriate and fair in its discretion and that may
         provide for the selection of a portion or portions (equal to
         twenty-five U.S. dollars ($25) or any integral multiple thereof) of
         the principal amount of such Debentures of a denomination larger than
         $25, the Debentures to be redeemed and shall thereafter promptly
         notify the Company in writing of the numbers of the Debentures to be
         redeemed, in whole or in part.

                 The Company may, if and whenever it shall so elect, by
         delivery of instructions signed on its behalf by its President or any
         Vice President, instruct the Trustee or any paying agent to call all
         or any part of the Debentures of a particular series for redemption
         and to give notice of redemption in the manner set forth in this
         Section, such notice to be in the name of the Company or its own name
         as the Trustee or such paying agent may deem advisable.  In any case
         in which notice of redemption is to be given by the Trustee or any
         such paying agent, the Company shall deliver or cause to be delivered
         to, or permit to remain with, the Trustee or such paying agent, as the
         case may be, such Security Register, transfer books or other records,
         or suitable copies or extracts therefrom, sufficient to enable the
         Trustee or such paying agent to give any notice by mail that may be
         required under the provisions of this Section.

SECTION 3.5.     PAYMENT UPON REDEMPTION.

                 (a)      If the giving of notice of redemption shall have been
         completed as above provided, the Debentures or portions of Debentures
         of the series to be redeemed specified in such notice shall become due
         and payable on the date and at the place stated in such notice at the
         applicable redemption price, together with interest accrued to the
         date fixed for redemption and interest on such Debentures or portions
         of Debentures shall cease to accrue on and after the date fixed for
         redemption, unless the Company shall default in the payment of such
         redemption price and accrued interest with respect to any such
         Security or portion thereof.  On presentation and surrender of such
         Debentures on or after the date fixed for redemption at the place of
         payment specified in the notice, said Debentures shall be paid and
         redeemed at the applicable redemption price for such series, together
         with interest accrued thereon to the date fixed for redemption (but if
         the date fixed for redemption is an interest payment date, the
         interest installment payable on such date shall be payable to the
         registered holder at the close of business on the applicable record
         date pursuant to Section 3.3).

                 (b)      Upon presentation of any Security of such series that
         is to be redeemed in part only, the Company shall execute and the
         Trustee shall authenticate and the office or agency where the Security
         is presented shall deliver to the holder thereof, at the expense of
         the Company, a new Security or Debentures of the same series of
         authorized denominations in principal amount equal to the unredeemed
         portion of the Security so presented.

SECTION 3.6.     NO SINKING FUND.

         The Debentures are not entitled to the benefit of  any sinking fund.

                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1.     EXTENSION OF INTEREST PAYMENT PERIOD.

         The Company shall have the right, at any time and from time to time
during the term of the Debentures, to defer payments of interest by extending
the interest payment period of such





                                       15
<PAGE>   21

Debentures for a period not exceeding 20 consecutive quarters (the "Extended
Interest Payment Period"), during which Extended Interest Payment Period no
interest shall be due and payable; provided that no Extended Interest Payment
Period may extend beyond the Maturity Date.  To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to this Section 4.1, will
bear interest thereon at the Coupon Rate compounded quarterly for each quarter
of the Extended Interest Payment Period ("Compounded Interest").  At the end of
the Extended Interest Payment Period, the Company shall pay all interest
accrued and unpaid on the Debentures, including any Additional Interest and
Compounded Interest (together, "Deferred Interest") that shall be payable to
the Holders of the Debentures in whose names the Debentures are registered in
the Security Register on the first record date after the end of the Extended
Interest Payment Period.  Before the termination of any Extended Interest
Payment Period, the Company may further extend such period, provided that such
period together with all such further extensions thereof shall not exceed 20
consecutive quarters, or extend beyond the maturity date of the Debentures.
Upon the termination of any Extended Interest Payment Period and upon the
payment of all Deferred Interest then due, the Company may commence a new
Extended Interest Payment Period, subject to the foregoing requirements.  No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof, but the Company may prepay at any time all or any
portion of the interest accrued during an Extended Interest Payment Period.

SECTION 4.2.     NOTICE OF EXTENSION.

                 (a)      If the Property Trustee is the only registered Holder
         of the Debentures at the time the Company selects an Extended Interest
         Payment Period, the Company shall give written notice to the
         Administrative Trustees, the Property Trustee and the Trustee of its
         selection of such Extended Interest Payment Period one Business Day
         before the earlier of (i) the next succeeding date on which
         Distributions on the Trust Securities issued by the Trust are payable,
         or (ii) the date the Trust is required to give notice of the record
         date, or the date such Distributions are payable, to the Nasdaq
         National Market or other applicable self-regulatory organization or to
         holders of the Preferred Securities issued by the Trust, but in any
         event at least one Business Day before such record date.


                 (b)      If the Property Trustee is not the only Holder of the
         Debentures at the time the Company selects an Extended Interest
         Payment Period, the Company shall give the Holders of the Debentures
         and the Trustee written notice of its selection of such Extended
         Interest Payment Period at least one Business Day  before the earlier
         of (i) the next succeeding Interest Payment Date, or (ii) the date the
         Company is required to give notice of the record or payment date of
         such interest payment to the Nasdaq National Market or other
         applicable self-regulatory organization or to Holders of the
         Debentures.

                 (c)      The quarter in which any notice is given pursuant to
         paragraphs (a) or (b) of this Section 4.2 shall be counted as one of
         the 20 quarters permitted in the maximum Extended Interest Payment
         Period permitted under Section 4.1.

SECTION 4.3.     LIMITATION OF TRANSACTIONS.

         If (i) the Company shall exercise its right to defer payment of
interest as provided in Section 4.1, or (ii) there shall have occurred any
Event of Default, as defined in the Indenture, then (a) the Company shall not
declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock (other than (i) purchases or acquisitions of shares of its

junior to the Debentures; provided, however, the Company may declare and pay a
stock dividend where the dividend stock is the same stock as that on which the
dividend is being paid.

         So long as any series of the Securities remain Outstanding, the
Company agrees to maintain an office or agency in the Borough of Manhattan, the
City and State of New York, with respect to each such series and at such other
location or locations as may be designated as provided in this Section 5.2,
where (i) Securities of that series may be presented for payment, (ii)
Securities of that series may be presented as hereinabove authorized for
registration of transfer and exchange, and (iii) notices and demands to or upon

be given or served, such designation to continue with respect to such office or
agency until the Company shall, by written notice signed by its President or a
Vice President and delivered to the trustee, designate some other office or
agency for such purposes or any of them.  If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the

be made or served at the Corporate Trust Office of the Trustee, and the Company
hereby appoints the Trustee as its agent to receive all such presentations,
notices and demands.

SECTION 5.3.     PAYING AGENTS.

                 (a)      If the Company shall appoint one or more paying
         agents for all or any series of the Securities, other than the
         Trustee, the Company will cause each such paying agent to execute and
         deliver to the Trustee an instrument in which such agent shall agree
         with the Trustee, subject to the provisions of this Section:

                          (i)     that it will hold all sums held by it as such
                 agent for the payment of the principal of (and premium, if
                 any) or interest on the Securities of that series (whether
                 such sums  have been paid to it by the Company or by any other
                 obligor of such Securities) in trust for the benefit of the
                 Persons entitled thereto;

                          (ii)    that it will give the Trustee notice of any
                 failure by the Company (or by any other obligor of such
                 Securities) to make any payment of the principal of (and
                 premium, if any) or interest on the Securities of that series
                 when the same shall be due and payable;

                          (iii)   that it will, at any time during the
                 continuance of any failure referred to in the preceding
                 paragraph (a)(2) above, upon the written request of the
                 Trustee, forthwith pay to the Trustee all sums so held in
                 trust by such paying agent; and

                          (iv)    that it will perform all other duties of
                 paying agent as set forth in this Indenture.

                 (b)      If the Company shall act as its own paying agent with
         respect to any series of the Securities, it will on or before each due
         date of the principal of (and premium, if any) or interest on
         Securities of that series, set aside, segregate and hold in trust for
         the benefit of the Persons entitled thereto a sum sufficient to pay
         such principal (and premium, if any) or interest so becoming due on
         Securities of that series until such sums shall be paid to such
         Persons or otherwise disposed of as herein provided and will promptly
         notify the Trustee of such action, or any failure (by it or any other
         obligor on such Securities) to take such action.  Whenever the Company
         shall have one or more paying agents for any series of Securities, it
         will, prior to each due date of the principal of (and premium, if any)
         or interest on any Securities of that series, deposit with the paying
         agent a sum sufficient to pay the principal (and premium, if any) or
         interest so becoming due, such sum to be held in trust for the benefit
         of the Persons entitled to such principal, premium or interest, and
         (unless such paying agent is the Trustee) the Company will promptly
         notify the Trustee of this action or failure so to act.

                 (c)      Notwithstanding anything in this Section to the
         contrary, (i) the agreement to hold sums in trust as provided in this
         Section is subject to the provisions of Section [11.5], and (ii) the
         Company may at any time, for the purpose of obtaining the satisfaction
         and discharge of this Indenture or for any other purpose, pay, or
         direct any paying agent to pay, to the Trustee all sums held in trust
         by the Company or such paying agent, such sums to be held by the
         Trustee upon the same terms and conditions as those upon which such 
         sums were





                                       18
<PAGE>   24

held by the Company or such paying agent; and, upon such payment by any paying
agent to the Trustee, such paying agent shall be released from all further
liability with respect to such money.

SECTION 5.4.     APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.

         The Company, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint, in the manner provided in Section 9.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

SECTION 5.5.     COMPLIANCE WITH CONSOLIDATION PROVISIONS.

         The Company will not, while any of the Securities remain outstanding,
consolidate with, or merge into, or merge into itself, or sell or convey all or
substantially all of its property to any other company unless the provisions of
Article Ten hereof are complied with.

SECTION 5.6.     LIMITATION ON DIVIDENDS; TRANSACTIONS WITH AFFILIATES.

         If Securities are issued to a IBC Capital or a trustee of such trust
in connection with the issuance of Trust Securities by IBC Capital and (i)
there shall have occurred any event that would constitute an Event of Default,
(ii) IBC Capital shall be in default with respect to its payment of any
obligations under the Preferred Securities Guarantee relating to IBC Capital or
(iii) the Company shall have given notice of its election to defer payments of
interest on such Securities by extending the interest payment period as
provided in the Indenture and such period, or any extension thereof, shall be
continuing, then (a) the Company shall not declare or pay any dividend on, make
any distributions with respect to, or redeem, purchase or make a liquidation
payment with respect to, any of its capital stock, and (b) the Company shall
not make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Company which rank pari
passu with or junior in interest to the Debentures; provided, however, that the
restriction in clause (a) above does not apply to any stock dividends paid by
the Company where the dividend stock is the same as that on which the dividend
is being paid.

SECTION 5.7.     COVENANTS AS TO IBC CAPITAL.

         For so long as such Trust Securities of IBC Capital remain
outstanding, the Company will (i) maintain 100% direct or indirect ownership of
the Common Securities of IBC Capital; provided, however, that any permitted
successor of the Company under the Indenture may succeed to the Company's
ownership of the Common Securities, (ii) use its reasonable efforts to cause
IBC Capital (a) to remain a business trust, except in connection with a
distribution of Securities, the redemption of all of the Trust Securities of
IBC Capital or certain mergers, consolidations or amalgamations, each as
permitted by the Trust Agreement of IBC Capital, and (b) to otherwise continue
not to be treated as an association taxable as a corporation or partnership for
United States federal income tax purposes and (iii) to use its reasonable
efforts to cause each holder of Trust Securities to be treated as owning an

SECTION 7.1.    EVENTS OF DEFAULT.



                                     21
<PAGE>   27




           (a) Whenever used herein with respect to Securities of a particular
      series, "Event of Default" means any one or more of the following events
      that has occurred and is continuing:

                 (i) the Company defaults in the payment of any installment of
            interest upon any of the Securities of that series, as and when the
            same shall become due and payable, and continuance of such default
            for a period of      days; provided, however, that a valid
            extension of an interest payment period by the Company in
            accordance with the terms of any indenture supplemental hereto,
            shall not constitute a default in the payment of interest for this
            purpose;

                 (ii) the Company defaults in the payment of the principal of
            (or premium, if any, on) any of the Securities of that series as
            and when the same shall become due and payable whether at maturity,
            upon redemption, by declaration or otherwise, or in any payment
            required by any sinking or analogous fund established with respect
            to that series; provided, however, that a valid extension of the
            maturity of such Securities in accordance with the terms of any
            indenture supplemental hereto shall not constitute a default in the
            payment of principal or premium, if any;

                 (iii) the Company fails to observe or perform any other of its
            covenants or agreements with respect to the Debentures or otherwise
            established with respect to the Debentures pursuant to Section 2.1
            hereof (other than a covenant or agreement that has been expressly
            included in this Indenture solely for the benefit of one or more
            series of Securities other than such series) for a period of 90
            days after the date on which written notice of such failure,
            requiring the same to be remedied and stating that such notice is a
            "Notice of Default" hereunder, shall have been given to the Company
            by the Trustee, by registered or certified mail, or to the Company
            and the Trustee by the holders of at least 25% in principal amount
            of the Securities of that series at the time Outstanding;

                 (iv) the Company pursuant to or within the meaning of any
            Bankruptcy Law (i) commences a voluntary case, (ii) consents to the
            entry of an order for relief against it in an involuntary case,
            (iii) consents to the appointment of a Custodian of it or for all
            or substantially all of its property or (iv) makes a general
            assignment for the benefit of its creditors;

                 (v) a court of competent jurisdiction enters an order under
            any Bankruptcy Law that (i) is for relief against the Company in an
            involuntary case, (ii) appoints a Custodian of the Company for all
            or substantially all of their respective property, or (iii) orders
            the liquidation of the Company or the Guarantor, and the order or
            decree remains unstayed and in effect for 90 days; or


                 (vi) in the event Securities are issued to a IBC Capital or a
            trustee of such trust in connection with the issuance of Trust
            Securities by IBC Capital, IBC Capital shall have voluntarily or
            involuntarily dissolved, wound-up its business or otherwise

                                     22


<PAGE>   28

            terminated its existence except in connection with (i) the
            distribution of Securities to holders of Trust Securities in
            liquidation of their interests in IBC Capital, (ii) the redemption
            of all of the outstanding Trust Securities of IBC Capital or (iii)
            certain mergers, consolidations or amalgamation, each as permitted
            by the Declaration of IBC Capital.

           (b) In each and every such case, unless the principal of all the
      Securities of that series shall have already become due and payable,
      either the Trustee or the holders of not less than 25% in aggregate
      principal amount of the Securities of that series then Outstanding
      hereunder, by notice in writing to the Company (and to the Trustee if
      given by such Securityholders) may declare the principal of all the
      Securities of that series to be due and payable  immediately, and upon
      any such declaration the same shall become and shall be immediately due
      and payable, notwithstanding anything contained in this Indenture or in
      the Securities of that series or established with respect to that series
      pursuant to Section 2.1 to the contrary.

           (c) At any time after the principal of the Securities of that series
      shall have been so declared due and payable, and before any judgment or
      decree for the payment of the moneys due shall have been obtained or
      entered as hereinafter provided, the holders of a majority in aggregate
      principal amount of the Securities of that series then Outstanding
      hereunder, by written notice to the Company and the Trustee, may rescind
      and annul such declaration and its consequences if: (i) the Company has
      paid or deposited with the Trustee a sum sufficient to pay all matured
      installments of interest upon all the Securities of that series and the
      principal of (and premium, if any, on) any and all Securities of that
      series that shall have become due otherwise than by acceleration (with
      interest upon such principal and premium, if any, and, to the extent that
      such payment is enforceable under applicable law, upon overdue
      installments of interest, at the rate per annum expressed in the
      Securities of that series to the date of such payment or deposit) and the
      amount payable to the Trustee under Section 7.6, and (ii) any and all
      Events of Default under the Indenture with respect to such series, other
      than the nonpayment of principal on Securities of that series that shall
      not have become due by their terms, shall have been remedied or waived as
      provided in Section 6.6.

           No such rescission and annulment shall extend to or shall affect any
      subsequent default or impair any right consequent thereon.

           (d) In case the Trustee shall have proceeded to enforce any right
      with respect to Securities of that series under this Indenture and such
      proceedings shall have been discontinued or abandoned because of such
      rescission or annulment or for any other reason or shall have been
      determined adversely to the Trustee, then and in every such case the
      Company and the Trustee shall be restored respectively to their former
      positions and rights hereunder, and all rights, remedies and powers of
      the Company and the Trustee shall continue as though no such proceedings
      had been taken.

SECTION 7.2.    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

           (a) The Company covenants that (1) in case it shall default in the
      payment of any installment of interest on any of the Securities of a
      series, or any payment required by any sinking or analogous fund
      established with respect to that series as and when the same shall have
      become due and payable, and such default shall have continued for a
      period of 90 Business Days, or (2) in case it shall default in the
      payment of the principal of (or premium, if any, on) any of the
      Securities of a series when the same shall have become due and payable,
      whether upon maturity of the Securities of a series or upon redemption or
      upon declaration or otherwise, then, upon demand of the Trustee the
      Guarantor will pay to the Trustee, for the benefit of the holders of the
      Securities of that series, the whole amount that then shall have been
      become due and payable on all such Securities for principal (and premium,
      if any) or interest, or both, as the case may be, with interest upon the
      overdue principal (and premium, if any) and (to the extent that payment
      of such interest is enforceable under applicable law and, if the
      Securities are held by a IBC Capital or a trustee of such trust, without
      duplication of any other amounts paid by IBC Capital or trustee in
      respect thereof) upon overdue installments of interest at the rate per
      annum expressed in the Securities of that series; and, in addition
      thereto, such further amount as shall be sufficient to cover the costs
      and expenses of collection, and the amount payable to the Trustee under
      Section 7.6.

           (b) If the Company shall fail to pay such amounts forthwith upon
      such demand, the Trustee, in its own name and as trustee of an express
      trust, shall be entitled and empowered to institute any action or
      proceedings at law or in equity for the collection of the sums so due and
      unpaid, and may prosecute any such action or proceeding to judgment or
      final decree, and may enforce any such judgment or final decree against
      the Company or other obligor upon the Securities of that series and
      collect the moneys adjudged or decreed to be payable in the manner
      provided by law out of the property of the Company or other obligor upon
      the Securities of that series, wherever situated.

           (c) In case of any receivership, insolvency, liquidation,
      bankruptcy, reorganization, readjustment, arrangement, composition or
      judicial proceedings affected the Company or the creditors or property of
      either, the Trustee shall have power to intervene in such proceedings and
      take any action therein that may be permitted by the court and shall
      (except as may be otherwise provided by law) be entitled to file such
      proofs of claim and other papers and documents as may be necessary or
      advisable in order to have the claims of the Trustee and of the holders
      of Securities of such series allowed for the entire amount due and
      payable by the Company under the Indenture at the date of institution of
      such proceedings and for any additional amount that may become due and
      payable by the Company after such date, and to collect and receive any
      moneys or other property payable or deliverable on any such claim, and to
      distribute the same after the deduction of the amount payable to the
      Trustee under Section 9.6; and any receiver, assignee or trustee in
      bankruptcy or reorganization is hereby authorized by each of the holders
      of Securities of such series to make such payments to the Trustee, and,
      in the event that the Trustee shall consent to the 


                                     24

<PAGE>   30
      making of such payments directly to such Securityholders, to pay to the 
      Trustee any amount due it under Section [9.6].

           (d) All rights of action and of asserting claims under this
      Indenture, or under any of the terms established with respect to
      Securities of that series, may be enforced by the Trustee without the
      possession of any of such Securities, or the production thereof at any
      trial or other proceeding relative thereto, and any such suit or
      proceeding instituted by the Trustee shall be brought in its own name as
      trustee of an express trust, and any recovery of judgment shall, after
      provision for payment to the Trustee of any amounts due under Section
      9.6, be for the ratable benefit of the holders of the Securities of such
      series.

           In case of an Event of Default hereunder, the Trustee may in its
      discretion proceed to protect and enforce the rights vested in it by this
      Indenture by such appropriate judicial proceedings as the Trustee shall
      deem most effectual to protect and enforce any of such rights, either at
      law or in equity or in bankruptcy or otherwise, whether for the specific
      enforcement of any covenant or agreement contained in the Indenture or in
      aid of the exercise of any power granted in this Indenture, or to enforce
      any other legal or equitable right vested in the Trustee by this
      Indenture or by law.

           Nothing contained herein shall be deemed to authorize the Trustee to
      authorize or consent to or accept or adopt on behalf of any
      Securityholder any plan of reorganization, arrangement, adjustment or
      composition affecting the Securities of that series or the rights of any
      holder thereof or to authorize the Trustee to vote in respect of the
      claim of any Securityholder in any such proceeding.

SECTION 7.3.    APPLICATION OF MONEYS COLLECTED

     Any moneys collected by the Trustee pursuant to this Article with respect
to a particular series of Securities shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of
such moneys on account of principal (or premium, if any) or interest, upon
presentation of the Securities of that series, and notation thereon the
payment, if only partially paid, and upon surrender thereof if
fully paid:

           FIRST: To the payment of costs and expenses of collection and of all
      amounts payable to the Trustee under Section 9.6;

           SECOND: To the payment of all Senior Indebtedness of the Company if
      and to the extent required by Article Fourteen; and

           THIRD: To the payment of the amounts then due and unpaid upon
      Securities of such series for principal (and premium, if any) and
      interest, in respect of which or for the benefit of which such money has
      been collected, ratably, without preference or priority of any kind,
      according to the amounts due and payable on such Securities for principal
      (and premium, if any) and interest, respectively.

SECTION 7.4.    LIMITATION ON SUITS.

     No holder of any Security of any series shall have any right by virtue or
by availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless (i) such holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof with
respect to the Securities of such series specifying such Event of Default, as
hereinbefore provided; (ii) the holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding shall have
made written request upon the Trustee to institute such action, suit or
proceeding in its own name as trustee hereunder; (iii) such holder or holders
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby;
and (iv) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity, shall have failed to institute any such action, suit or
proceeding and (v) during such 60 day period, the holders of a majority in
principal amount of the Securities of that series do not give the Trustee a
direction inconsistent with the request.

     Notwithstanding anything contained herein to the contrary, any other
provisions of this Indenture, the right of any holder of any Security to
receive payment of the principal of (and premium, if any) and interest on such
Security, as therein provided, on or after the respective due dates expressed
in such Security (or in the case of redemption, on the redemption date), or to
institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected without
the consent of such holder and by accepting a Security hereunder it is
expressly understood, intended and covenanted by the taker and holder of every
Security of such series with every other such taker and holder and the Trustee,
that no one or more holders of Securities of such series shall have any right
in any manner whatsoever by virtue or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of the holders of any
other of such Securities, or to obtain or seek to obtain priority over or
preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of Securities of series.  For the protection and
enforcement of the provisions of this Section, each and every Securityholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.


SECTION 7.5.    RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER.

           (a) Except as otherwise provided in Section 2.7, all powers and
      remedies given by this Article to the Trustee or to the Securityholders
      shall, to the extent permitted by law, be deemed cumulative and not
      exclusive of any other powers and remedies available to the Trustee or
      the holders of the Securities, by judicial proceedings or otherwise, to
      enforce the performance or observance of the covenants and agreements
      contained in this Indenture or otherwise established with respect to such
      Securities.

           (b) No delay or omission of the Trustee or of any holder of any of
      the Securities to exercise any right or power accruing upon any Event of
      Default occurring and continuing


                                     26

<PAGE>   32

      as aforesaid shall impair any such right or power, or shall be construed
      to be a waiver of any such default or on acquiescence therein; and, 
      subject to the provisions of Section 7.4, every power and remedy given 
      by this Article or by law to the Trustee or the Securityholders may be 
      exercised from time to time, and as often as shall be deemed expedient, 
      by the Trustee or by the Securityholders.

SECTION 7.6.    CONTROL BY SECURITYHOLDERS.

     The holders of a majority in aggregate principal amount of the Securities
of any series at the time Outstanding, determined in accordance with Section
10.4, shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee with respect to such series; provided,
however, that such direction shall not be in conflict with any rule of law or
with this Indenture or be unduly prejudicial to the rights of holders of
Securities of any other series at the time Outstanding determined in accordance
with Section ______ hereof.  Subject to the provisions of Section 9.1, the
Trustee shall have the right to decline to follow any such direction if the
Trustee in good faith shall, by a Responsible Officer or Officers of the
Trustee, determine that the proceeding so directed would involve the Trustee in
personal liability.  The holders of a majority in aggregate principal amount of
the Securities of any series at the time Outstanding affected thereby,
determined in accordance with Section ____, may on behalf of the holders of
all of the Securities of such series waive any past default in the performance
of any of the covenants contained herein or established pursuant to Section 2.1
with respect to such series and its consequences, except (i) a default in the
payment of the principal of, or premium, if any, or interest on, any of the
Securities of that series as and when the same shall become due by the terms of
such Securities otherwise than by acceleration (unless such default has been
cured and a sum sufficient to pay all matured installments of interest and
principal and any premium has been deposited with the Trustee (in accordance
with Section 6.1(c)), (ii) a default in the covenants contained in Section 4.6
or (iii) in respect of a covenant or provision hereof which under Article Nine
cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected; provided, however, that if the

such waiver or modification to such waiver shall not be effective until the
holders of a majority in liquidation preference of Trust Securities of the
applicable IBC Capital shall have consented to such waiver or modification to
such waiver; provided further, that if the consent of the Holder of each
Outstanding Debt Security is required, such waiver shall not be effective until
each holder of the Trust Securities of the applicable IBC Capital shall have
consented to such waiver.  Upon any such waiver, the default covered thereby
shall be deemed to be cured for all purposes of this Indenture and the Company,
the Trustee and the holders of the Securities of such series shall be restored
to their former positions and rights hereunder, respectively; but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

such holder's acceptance thereof shall be deemed to have agreed, that any court

remedy under this Indenture, or in any suit against the 

                                     27

Trustee for any action taken or omitted by it as Trustee, the filing by
any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made
by such party litigant; but the provisions of this Section shall not apply to
any suit instituted by the Trustee, to any suit instituted by any
Securityholder, or group of Securityholders, holding more than 10% in aggregate
principal amount of the Outstanding Securities of any series, or to any suit
instituted by any Securityholder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Security of such series,

SECTION 9.1.    CERTAIN DUTIES AND RESPONSIBILITIES TRUSTEE.

           (a) The Trustee prior to the occurrence of an Event of Default with
      respect to the Securities of a series and after the curing of all Events
      of Default with respect to the Securities of that series that may have
      occurred, shall undertake to perform with respect to the Securities of
      such series such duties and only such duties as are specifically set
      forth in this Indenture, and no implied covenants shall be read into this
      Indenture against the Trustee.  In case an Event of Default with respect
      to the Securities of a series has occurred (that has not been cured or
      waived), the Trustee shall exercise with respect to Securities of that
      series such of the rights and powers vested in it by this Indenture, and
      use the same degree of care and skill in their exercise, as a prudent man
      would exercise or use under the circumstances in the conduct of his own
      affairs.


                                     28

<PAGE>   34


           (b) No provision of this Indenture shall be construed to relieve the
      Trustee from liability for its own negligent action, its own negligent
      failure to act, or its own willful misconduct, except that:

                 (1) prior to the occurrence of an Event of Default with
            respect to the Securities of a series and after the curing or
            waiving of all such Events of Default with respect to that series
            that may have occurred:

                       (i) the duties and obligations of the Trustee shall with
                  respect to the Securities of such series be determined solely
                  by the express provisions of this Indenture, and the Trustee
                  shall not be liable with respect to the Securities of such
                  series except for the performance of such duties and
                  obligations as are specifically set forth in this Indenture,
                  and no implied covenants or obligations shall be read into
                  this Indenture against the Trustee; and

                       (ii) in the absence of bad faith on the part of the
                  Trustee, the Trustee may with respect to the Securities of
                  such series conclusively rely, as to the truth of the
                  statements and the correctness of the opinions expressed
                  therein, upon any certificates or opinions furnished to  the
                  Trustee and conforming to the requirements of this Indenture;
                  but in the case of any such certificates or opinions that by
                  any provision hereof are specifically required to be
                  furnished to the Trustee, the Trustee shall be under a duty
                  to examine the same to determine whether or not they conform
                  to the requirement of this Indenture;

                 (2) the Trustee shall not be liable for any error of judgment
            made in good faith by a Responsible Officer or Responsible Officers
            of the Trustee, unless it shall be proved that the Trustee, was
            negligent in ascertaining the pertinent facts;

                 (3) the Trustee shall not be liable with respect to any action
            taken or omitted to be taken by it in good faith in accordance with
            the direction of the holders of not less than a majority in
            principal amount of the Securities of any series at the time
            Outstanding relating to the time, method and place of conducting
            any proceeding for any remedy available to the Trustee, or
            exercising any trust or power conferred upon the Trustee under this
            Indenture with respect to the Securities of that series; and

                 (4) None of the provisions contained in this Indenture shall
            require the Trustee to expend or risk its own funds or otherwise
            incur personal financial liability in the performance of any of its
            duties or in the exercise of any of its rights or powers, if there
            is reasonable ground for believing that the repayment of such funds
            or liability is not reasonably assured to it under the terms of
            this Indenture or adequate indemnity against such risk is not
            reasonably assured to it.

SECTION 9.2.    CERTAIN RIGHTS OF TRUSTEE.

      Except as otherwise provided in Section 9.1:

           (a) The Trustee may rely and shall be protected in acting or
      refraining from acting upon any resolution, certificate, statement,
      instrument, opinion, report, notice, request, consent, order, approval,
      bond, security or other paper or document believed by it to be genuine
      and to have been signed or presented by the proper party or parties;

           (b) Any request, direction, order or demand of the Company mentioned
      herein shall be sufficiently evidenced by a Board Resolution or an
      instrument signed in the name of the Company by the President or any Vice
      President and by the Secretary or an Assistant Secretary or the Treasurer
      or an Assistant Treasurer thereof (unless other evidence in respect
      thereof is specifically prescribed herein);

           (c) The Trustee may consult with counsel and the written advice of
      such counsel or any Opinion of Counsel shall be full and complete
      authorization and protection in respect of any action taken or suffered
      or omitted hereunder in good faith and in reliance thereon;

           (d) The Trustee shall be under no obligation to exercise any of the
      rights or powers vested in it by this Indenture at the request, order or
      direction of any of the Securityholders, pursuant to the provisions of
      this Indenture, unless such Securityholders shall have offered to the
      Trustee reasonable security or indemnity against the costs, expenses and
      liabilities that may be incurred therein or thereby; nothing contained
      herein shall, however, relieve the Trustee of the obligation, upon the
      occurrence of an Event of Default with respect to a series of the
      Securities (that has not been cured or waived) to exercise with respect
      to Securities of that series such of the rights and powers vested in it
      by this Indenture, and to use the same degree of care and skill in their
      exercise, as a prudent man would exercise or use under the circumstances
      in the conduct of his own affairs;

           (e) The Trustee shall not be liable for any action taken or omitted
      to be taken by it in good faith and believed by it to be authorized or
      within the discretion or rights or powers conferred upon it by this
      Indenture;

           (f) The Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate, statement,
      instrument, opinion, report, notice, request, consent, order, approval,
      bond, security, or other papers or documents, unless requested in writing
      so to do by the holders of not less than a majority in principal amount
      of the Outstanding Securities of the particular series affected thereby
      (determined as provided in Section 10.4); provided, however, that if the
      payment within a reasonable time to the Trustee of the costs, expenses or
      liabilities likely to be incurred by it in the making of such
      investigation is, in the opinion of the Trustee, not reasonably assured
      to the Trustee by the security afforded to it by the terms of this
      Indenture, the Trustee may require reasonable indemnity against such 
      costs, expenses or liabilities as a condition to so proceeding.  The 


                                     30

<PAGE>   36

      reasonable expense of every such examination shall be paid by the Company 
      or, if paid by the Trustee, shall be repaid by the Company upon demand; 
      and

           (g) The Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents or
      attorneys and the Trustee shall not be responsible for any misconduct or
      negligence on the part of any agent or attorney appointed with due care
      by it hereunder.


SECTION 9.3.    TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OR SECURITIES.

           (a) The recitals contained herein and in the Securities shall be
      taken as the statements of the Company and the Trustee assumes no
      responsibility for the correctness of the same.

           (b) The Trustee makes no representations as to the validity or
      sufficiency of this Indenture or of the Securities.

           (c) The Trustee shall not be accountable for the use or application
      by the Company of any of the Securities or of the proceeds of such
      Securities, or for the use or application of any moneys paid over by the
      Trustee in accordance with any provision of this Indenture or established
      pursuant to Section 2.1, or for the use or application of any moneys
      received by any paying agent other than the Trustee.


SECTION 9.4.    MAY HOLD SECURITIES.

     The Trustee or any paying agent or Security Registrar, in its individual
or any other capacity, may become the owner or pledgee of Securities with the
same rights it would have if it were not Trustee, paying agent or Security
Registrar.

SECTION 9.5.    MONEYS HELD IN TRUST.

     Subject to the provisions of Section [13.5], all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from
other funds except to the extent required by law.  The Trustee shall be under
no liability for interest on any moneys received by it hereunder except such as
it may agree with the Company to pay thereon.

SECTION 9.6.    COMPENSATION AND REIMBURSEMENT.

           (a) The Company covenants and agrees to pay to the Trustee, and the
      Trustee shall be entitled to, such reasonable compensation (which shall
      not be limited by any provision of law in regard to the compensation of a
      trustee of an express trust), as the Company and the Trustee may from
      time to time agree in writing, for all services rendered by it in the
      execution of the trusts hereby created and in the exercise and
      performance of any of the powers and duties hereunder of the Trustee,
      and, except as otherwise expressly 


                                     31


<PAGE>   37

      provided herein, the Company will pay or reimburse the Trustee upon its
      request for all reasonable expenses, disbursements and advances incurred
      or made by the Trustee in accordance with any of the provisions of this
      Indenture (including the reasonable compensation and the expenses and
      disbursements of its counsel and of all Persons not regularly in its
      employ) except any such expense, disbursement or advance as may arise
      from its negligence or bad faith. The Company also covenants to indemnify
      the Trustee (and its officers, agents, directors and employees) for, and
      to hold it harmless against, any loss, liability or expense incurred
      without negligence or bad faith on the part of the Trustee and arising
      out of or in connection with the acceptance or administration of this
      trust, including the costs and expenses of defending itself against any
      claim of liability in the premises.

           (b) The obligations of the Company under this Section to compensate
      and indemnify the Trustee and to pay or reimburse the Trustee for
      expenses, disbursements and advances shall constitute additional
      indebtedness hereunder.  Such additional indebtedness shall be secured by
      a lien prior to that of the Securities upon all property and funds held
      or collected by the Trustee as such, except funds held in trust for the
      benefit of the holders of particular Securities.

SECTION 9.7.    RELIANCE ON OFFICERS' CERTIFICATE.

     Except as otherwise provided in Section _______ whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking
or suffering or omitting to take any action hereunder, such matter (unless
other evidence in respect thereof be herein specifically prescribed) may, in
the absence of negligence or bad faith on the part of the Trustee, be deemed to
be conclusively proved and established by an Officers' Certificate delivered to
the Trustee and such certificate, in the absence of negligence or bad faith on
the part of the Trustee, shall be full warrant to the Trustee for any action
taken, suffered or omitted to be taken by it under the provisions of this
Indenture upon the faith thereof.

SECTION 9.8.    DISQUALIFICATION:  CONFLICTING INTERESTS.

     If the Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

SECTION 9.9.    CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There shall at all times be a Trustee with respect to the Securities
issued hereunder which shall at all times be a corporation organized and doing
business under the laws of the United States of America or any State or
Territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the Commission, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least 50 million U.S. dollars ($50,000,000), and subject to supervision 
or examination by Federal, State, Territorial, or District of Columbia 
authority.  If such corporation publishes reports of condition at least 
annually, pursuant to law or to the requirements of the aforesaid supervising 
or examining authority, then for the 



                                     32


<PAGE>   38
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its 
most recent report of condition so published.  The Company may not, nor
may any Person directly or indirectly controlling, controlled by, or under
common control with the Company, serve as Trustee.  In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 7.10.

SECTION 9.10.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

           (a) The Trustee or any successor hereafter appointed, may at any
      time resign with respect to the Securities of one or more series by
      giving written notice thereof to the Company and by transmitting notice
      of resignation by mail, first class postage prepaid, to the
      Securityholders of such series, as their names and addresses appear upon
      the Security Register.  Upon receiving such notice of resignation, the
      Company shall promptly appoint a successor trustee with respect to
      Securities of such series by written instrument, in duplicate, executed
      by order of the Board of Directors, one copy of which instrument shall be
      delivered to the resigning Trustee and one copy to the successor trustee.
      If no successor trustee shall have been so appointed and have accepted
      appointment within 30 days after the mailing of such notice of
      resignation, the resigning Trustee may petition any court of competent
      jurisdiction for the appointment of a successor trustee with respect to
      Securities of such series, or any Securityholder of that series who has
      been a bona fide holder of a Security or Securities for at least six
      months may, subject to the provisions of Section [6.8], on behalf of
      himself and all others similarly situated, petition any such court for
      the appointment of a successor trustee.  Such court may thereupon after
      such notice, if any, as it may deem proper and prescribe, appoint a
      successor trustee.

           (b) In case at any time any one of the following shall occur:

                 (i) the Trustee shall fail to comply with the provisions of
            subsection (a) of Section 9.8 after written request therefor by the
            Company or the Guarantor or by any Securityholder who has been a
            bona fide holder of a Security or Securities for at least six
            months; or

                 (ii) the Trustee shall cease to be eligible in accordance with
            the provisions of Section 9.9 and shall fail to resign after
            written request therefor by the Company or by any such
            Securityholder; or

                 (iii) the Trustee shall become incapable of acting, or shall
            be adjudged a bankrupt or insolvent, or commence a voluntary
            bankruptcy proceeding, or a receiver of the Trustee or of its
            property shall be appointed or consented to, or any public officer
            shall take charge or control of the Trustee or of its property or
            affairs for the purpose of rehabilitation, conservation or
            liquidation, then, in any such case, the Company may remove the
            Trustee with respect to all Securities and appoint a successor
            trustee by written instrument, in duplicate, executed by order of
            the Board of Directors, one copy of which instrument shall be
            delivered to the Trustee so 



                                     33

<PAGE>   39

            removed and one copy to the successor trustee, or, subject to
            the provisions of Section 7.8, unless the Trustee's duty to resign
            is stayed as provided herein, any Securityholder who has been a
            bona fide holder of a Security or Securities for at least six
            months may, on behalf of that holder and all others similarly
            situated, petition any court of competent jurisdiction for the
            removal of the Trustee and the appointment of a successor trustee. 
            Such court may thereupon after such notice, if any, as it may deem
            proper and prescribe, remove the Trustee and appoint a successor
            trustee.

           (c) The holders of a majority in aggregate principal amount of the
      Securities of any series at the time Outstanding may at any time remove
      the Trustee with respect to such series by so notifying the Trustee and
      the Company and may appoint a successor Trustee for such series with the
      consent of the Company.

           (d) Any resignation or removal of the Trustee and appointment of a
      successor trustee with respect to the Securities of a series pursuant to
      any of the provisions of this Section shall become effective upon
      acceptance of appointment by the successor trustee as provided in Section
      9.11.

           (e) Any successor trustee appointed pursuant to this Section may be
      appointed with respect to the Securities of one or more series or all of
      such series, and at any time there shall be only one Trustee with respect
      to the Securities of any particular series.

SECTION 9.11.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

           (a) In case of the appointment hereunder of a successor trustee with
      respect to all Securities, every such successor trustee so appointed
      shall execute, acknowledge and deliver to the Company and to the retiring
      Trustee an instrument accepting such appointment, and thereupon the
      resignation or removal of the retiring Trustee shall become effective and
      such successor trustee, without any further act, deed or conveyance,
      shall become vested with all the rights, powers, trusts and duties of the
      retiring Trustee; but, on the request of the Company or the successor
      trustee, such retiring Trustee shall, upon payment of its charges,
      execute and deliver an instrument transferring to such successor trustee
      all the rights, powers, and trusts of the retiring Trustee and shall duly
      assign, transfer and deliver to such successor trustee all property and
      money held by such retiring Trustee hereunder.

           (b) In case of the appointment hereunder of a successor trustee with
      respect to the Securities of one or more (but not all) series, the
      Company, the retiring Trustee and each successor trustee with respect to
      the Securities of one or more series shall execute and deliver an
      indenture supplemental hereto wherein each successor trustee shall accept
      such appointment and which (1) shall contain such provisions as shall be
      necessary or desirable to transfer and confirm to, and to vest in, each
      successor trustee all the rights, powers, trusts and duties of the
      retiring Trustee with respect to the Securities of that or those series
      to which the appointment of such successor trustee relates, (2) shall
      contain such provisions as 



                                     34

<PAGE>   40

      shall be deemed necessary or desirable to confirm that all the rights,
      powers, trusts and duties of the retiring Trustee with respect to the
      Securities of that or those series as to which the retiring Trustee is
      not retiring shall continue to be vested in the retiring Trustee, and (3)
      shall add to or change any of the provisions of this Indenture as shall
      be necessary to provide for or facilitate the administration of the
      trusts hereunder by more than one Trustee, it being understood that
      nothing herein or in such supplemental indenture shall constitute such
      Trustees co-trustees of the same trust, that each such Trustee shall be
      trustee of a trust or trusts hereunder separate and apart from any trust
      or trusts hereunder administered by any other such Trustee and that no
      Trustee shall be responsible for any act or failure to act on the part of
      any other Trustee hereunder; and upon the execution and delivery of such
      supplemental indenture the resignation or removal of the retiring Trustee
      shall become effective to the extent provided therein, such retiring
      Trustee shall with respect to the Securities of that or those series to
      which the appointment of such successor trustee relates have no further
      responsibility for the exercise of rights and powers or for the
      performance of the duties and obligations vested in the Trustee under
      this Indenture, and each such successor trustee, without any further act,
      deed or conveyance, shall become vested with all the rights, powers,
      trusts and duties of the retiring Trustee with respect to the Securities
      of that or those series to which the appointment of such successor
      trustee relates; but, on request of the Company or any successor trustee,
      such retiring Trustee shall duly assign, transfer and deliver to such
      successor trustee, to the extent contemplated by such supplemental
      indenture, the property and money held by such retiring Trustee hereunder
      with respect to the Securities of that or those series to which the
      appointment of such successor trustee relates.

           (c) upon request of any such successor trustee, the Company shall
      execute any and all instruments for more fully and certainly vesting in
      and confirming to such successor trustee all such rights, powers and
      trusts referred to in paragraph (a) or (b) of this Section, as the case
      may be.

           (d) No successor trustee shall accept its appointment unless at the
      time of such acceptance such successor trustee shall be qualified and
      eligible under this Article.

           (e) Upon acceptance of appointment by a successor trustee as
      provided in this Section, the Company shall transmit notice of the
      succession of such trustee hereunder by mail, first class postage
      prepaid, to the Securityholders, as their names and addresses appear upon
      the Security Register.  If the Company fails to transmit such notice
      within ten days after acceptance of appointment by the successor trustee,
      the successor trustee shall cause such notice to be transmitted at the
      expense of the Company and the Guarantor.


SECTION 9.12.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be



                                     35
<PAGE>   41
qualified under the provisions of Section 7.8 and eligible under the provisions
of Section 7.9, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.  In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion
or consolidation to such authenticating Trustee may adopt such authentication
and deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

SECTION 9.13.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.


                                  ARTICLE X
                       CONCERNING THE SECURITYHOLDERS

SECTION 10.1.   EVIDENCE OF ACTION BY SECURITYHOLDERS.

     Whenever in this Indenture it is provided that the holders of a majority
or specified percentage in aggregate principal amount of the Securities of a
particular series may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action the holders of
such majority or specified percentage of that series have joined therein may be
evidenced by any instrument or any number of instruments of similar tenor
executed by such holders of Securities of that series in Person or by agent or
proxy appointed in writing.

     If the Company shall solicit from the Securityholders of any series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of Outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the Outstanding Securities of that series
shall be computed as of the record date; provided, however, that no such
authorization, agreement or consent by such Securityholders on the record date
shall be deemed effective unless it shall become effective pursuant to the 
provisions of this Indenture not later than six months after the record date.



                                     36

SECTION 10.2.   PROOF OF EXECUTION BY SECURITYHOLDERS.

     Subject to the provisions of Section 7.1, proof of the execution of any
instrument by a Securityholder (such proof will not require notarization) or
his agent or proxy and proof of the holding by any Person of any of the
Securities shall be sufficient if made in the following manner:

           (a) The fact and date of the execution by any such Person of any
      instrument may be proved in any reasonable manner acceptable to the
      Trustee.

           (b) The ownership of Securities shall be proved by the Security
      Register of such Securities or by a certificate of the Security Registrar
      thereof.

           (c) The Trustee may require such additional proof of any matter
      referred to in this Section as it shall deem necessary.

SECTION 10.3.   WHO MAY BE DEEMED OWNERS.

     Prior to the due presentment for registration of transfer of any Security,
the Company, the Trustee, any paying agent and any Security Registrar may deem
and treat the Person in whose name such Security shall be registered upon the
books of the Company as the absolute owner of such Security (whether or not
such Security shall be overdue and notwithstanding any notice of ownership or
writing thereon made by anyone other than the Security Registrar) for the
purpose of receiving payment of or on account of the principal of, premium, if
any, and (subject to Section 2.3) interest on such Security and for all other
purposes; and neither the Company nor the Trustee nor any paying agent nor any
Security Registrar shall be affected by any notice to the contrary.

SECTION 10.4.   CERTAIN SECURITIES OWNED BY COMPANY DISREGARDED.

     In determining whether the holders of the requisite aggregate principal
amount of Securities of a particular series have concurred in any direction,
consent of waiver under this Indenture, the Securities of that series that are
owned by the Company or any other obligor on the Securities of that series or
by any Person directly or indirectly controlling or controlled by or under
common control with the Company or any other obligor on the Securities of that
series shall be disregarded and deemed not to be Outstanding for the purpose of
any such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver,
only Securities of such series that the Trustee actually knows are so owned
shall be so disregarded.  The Securities so owned that have been pledged in
good faith may be regarded as Outstanding for the purposes of this Section, if
the pledgee shall establish to the satisfaction of the Trustee the pledgee's
right so to act with respect to such Securities and that the pledgee is not a
Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any such other obligor.  In case of
a dispute as to such right, any decision by the Trustee taken upon the advice
of counsel shall be full protection to the Trustee.

SECTION 10.5.   ACTIONS BINDING ON FUTURE SECURITYHOLDERS.

     At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.1, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Securities of a
particular series specified in this Indenture in connection with such action,
any holder of a Security of that series that is shown by the evidence to be
included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.2, revoke such action so far as concerns such Security.
Except as aforesaid any such action taken by the holder of any Security shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Security, and of any Security issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether
or not any notation in regard thereto is made upon such Security.  Any action
taken by the holders of the majority or percentage in aggregate principal
amount of the Securities of a particular series specified in this Indenture in
connection with such action shall be conclusively binding upon the Company, the
Trustee and the holders of all the Securities of that series.


                                 ARTICLE XI.
                           SUPPLEMENTAL INDENTURES

SECTION 11.1.   SUPPLEMENTAL INDENTURES WITHOUT THE CONSENT OF SECURITYHOLDERS.

     In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect), without the
consent of the Securityholders, for one or more of the following purposes:

           (a) to cure any ambiguity, defect, or inconsistency herein, in the
      Securities of any series;

           (b) to comply with Article Ten;

           (c) to provide for uncertificated Securities in addition to or in
      place of certificated Securities;

           (d) to add to the covenants of the Company for the benefit of the
      holders of all or any Series of Securities (and if such covenants are to
      be for the benefit of less than all series of Securities, stating that
      such covenants are expressly being included solely for the benefit of
      such series) or to surrender any right or power herein conferred upon the
      Company;

           (e) to add to, delete from, or revise the conditions, limitations,
      and restrictions on the authorized amount, terms, or purposes of issue,
      authentication, and delivery of Securities, as herein set forth;




                                     38
<PAGE>   44


           (f) to make any change that does not adversely affect the rights of
      any Securityholder in any material respect; or

           (g) to provide for the issuance of and establish the form and terms
      and conditions of the Securities of any series, to establish the form of
      any certifications required to be furnished pursuant to the terms of this
      Indenture or any series of Securities, or to add to the rights of the
      holders of any series of Securities.

     The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, and to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee
shall not be obligated to enter into any such supplemental indenture that
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

     Any supplemental indenture authorized by the provisions of this Section
may be executed by the Company and the Trustee without the consent of the
holders of any of the Securities at the time Outstanding, notwithstanding any
of the provisions of Section 9.2.

SECTION 11.2.   SUPPLEMENTAL INDENTURES WITH CONSENT OF SECURITYHOLDERS.

     With the consent (evidenced as provided in Section 8.1) of the holders of
not less than a majority in aggregate principal amount of the Securities of
each series affected by such supplemental indenture or indentures at the time
Outstanding, the Company, when authorized by Board Resolutions, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture
or of any supplemental indenture or of modifying in any manner not covered by
Section 11.1 the rights of the holders of the Securities of such series under
this Indenture; provided, however, that no such supplemental indenture shall
without the consent of the holders of each Debenture then Outstanding and
affected thereby, (i) extend the fixed maturity of any Securities of any
series, or reduce the principal amount thereof, or reduce the rate or extend
the time of payment of interest thereon, or reduce any premium payable upon the
redemption thereof, without the consent of the holder of each Security so
affected or (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to consent to any such supplemental indenture provided,
further, that if the Debentures of such series are held by a IBC Capital or a
trustee of such trust, such supplemental indenture shall not be effective until
the holders of a majority in liquidation preference of Trust Securities of the
applicable Trust shall have consented to such supplemental indenture; provided
further, that if the consent of the Holder of each Outstanding Debt Security is
required, such supplemental indenture shall not be effective until each holder
of the Trust Securities of the applicable IBC Capital shall have consented to
such supplemental indenture.

     It shall not be necessary for the consent of the Securityholders of any
series affected thereby under this Section to approve the particular form of
any proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

SECTION 11.3.   EFFECT OF SUPPLEMENTAL INDENTURES.

     Upon the execution of any supplemental indenture pursuant to the
provisions of this Article or of Section 10.1, this Indenture shall, with
respect to such series, be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Securities of the series affected thereby shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

SECTION 11.4.   SECURITIES AFFECTED BY SUPPLEMENTAL INDENTURES.

     Securities of any series, affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this Article or of Section [10.1], may bear a
notation in form approved by the Company, provided such form meets the
requirements of any exchange upon which such series may be listed, as to any
matter provided for in such series may be listed, as to any matter provided for
in such supplemental indenture.  If the Company shall so determine, new
Securities of that series so modified as to conform, in the opinion of the
Board of Directors of the Company, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Company,
authenticated by the Trustee and delivered in exchange for the Securities of
that series then Outstanding.

SECTION 11.5.   EXECUTION OF SUPPLEMENTAL INDENTURES.

     Upon the request of the Company, accompanied by their Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders required
to consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture.  The Trustee, subject to
the provisions of Section 7.1, may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in
the execution thereof.

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall transmit by mail, first class postage prepaid, a notice, setting forth in
general terms the substance of such supplemental indenture, to the
Securityholders of all series affected thereby as their names and addresses
appear upon the Security Register.  Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

SECTION 12.1.    COMPANY MAY CONSOLIDATE, ETC.

         Nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of the Company with or into any other
corporation or corporations (whether or not affiliated with the Company, as the
case may be), or successive consolidations or mergers in which the Company, as
the case may be, or its successor or successors shall be a party or parties, or
shall prevent any sale, conveyance, transfer or other disposition of the
property of the Company, as the case may be, or its successor or successors as
an entirety, or substantially as an entirety, to any other corporation (whether
or not affiliated with the Company, as the case may be, or its successor or
successors) authorized to acquire and operate the same; provided, however, the
Company hereby covenants and agree that, upon any such consolidation, merger,
sale, conveyance, transfer or other disposition, the due and punctual payment,
in the case of the Company, of the principal of (premium, if any) and interest
on all of the Debentures of all series in accordance with the terms of each
series, according to their tenor and the due and punctual performance and
observance of all the covenants and conditions of this Indenture with respect
to each series or established with respect to such series pursuant to Section
2.1 to be kept or performed by the Company as the case may be, shall be
expressly assumed, by supplemental indenture (which shall conform to the
provisions of the Trust Indenture Act, as then in effect) satisfactory in form
to the Trustee executed and delivered to the Trustee by the entity formed by
such consolidation, or into which the Company, as the case may be, shall have
been merged, or by the entity which shall have acquired such property.

SECTION 12.2.    SUCCESSOR CORPORATION SUBSTITUTED.

                 (a)      In case of any such consolidation, merger, sale,
         conveyance, transfer or other disposition and upon the assumption by
         the successor corporation, by supplemental indenture, executed and
         delivered to the Trustee and satisfactory in form to the Trustee, of,
         in the case of the Company, the due and punctual payment of the
         principal of, premium, if any, and interest on all of the Debentures

         of the covenants and conditions of this Indenture or established with
         respect to each series of the Securities pursuant to Section 2.1 to be
         performed by the Company, as the case may be, with respect to each
         series, such successor corporation shall succeed to and be substituted
         for the Company, as the case may be, with the same effect as if it had
         been named as the Company, as the case may be, herein, and thereupon
         the predecessor corporation shall be relieved of all obligations and
         covenants under this Indenture and the Securities.

                 (b)      In case of any such consolidation, merger, sale,
         conveyance, transfer or other disposition such changes in phraseology
         and form (but not in substance) may be made in the Securities
         thereafter to be issued as may be appropriate.

                 (c)      Nothing contained in this Indenture or in any of the
         Securities shall prevent the Company from merging into itself or
         acquiring by purchase or otherwise all or any part of the property of
         any other Person (whether or not affiliated with the Company).

SECTION 12.3.    EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE.

         The Trustee, subject to the provisions of Section 7.1, may receive an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or other disposition, and any such assumption,
comply with the provisions of this Article.

whose payment money or Governmental Obligations have theretofore been deposited
in trust or segregated and held in trust by the Company (and thereupon repaid
to the Company or discharged from such trust, as provided in Section 13.5); or
all such Securities of a particular series not theretofore delivered to the
Trustee for cancellation shall have become due and payable, or are by their

redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption, and the Company shall deposit or cause to

Governmental Obligations sufficient or a combination thereof, sufficient in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
at maturity or upon redemption all Securities of that series not theretofore
delivered to the Trustee for cancellation, including principal (and premium, if
any) and interest due or to become due to such date of maturity or date fixed
for redemption, as the case may be, and if the Company shall also pay or cause
to be paid all other sums payable hereunder with respect to such series by the
Company; then this Indenture shall thereupon cease to be of further effect with
respect to such series except for the provisions of Sections 2.3, 2.5, 2.7,
4.1, 4.2, 4.3 and 9.10, that shall survive until the date of maturity or
redemption date, as the case may be, and Sections 9.6 and 13.5, that shall
survive to such date and thereafter, and the Trustee, on demand of the Company
and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture with respect to
such series.

SECTION 13.2.    DISCHARGE OF OBLIGATIONS.

         If at any time all such Securities of a particular series not
heretofore delivered to the Trustee for cancellation or that have not become
due and payable as described in Section 11.1 shall have been paid by the
Company by depositing irrevocably with the Trustee as trust funds moneys or an
amount of Governmental Obligations sufficient to pay at maturity or upon
redemption all such Securities of that series not theretofore delivered to the
Trustee for cancellation, including principal

maturity or date fixed for redemption, as the case may be, and if the Company
shall also pay or cause to be paid all other sums payable hereunder by the
Company with respect to such series, then after the date such moneys or
Governmental Obligations, as the case may be, are deposited with the Trustee
the obligations of the Company under this Indenture with respect to such series
shall cease to be of further effect except for the provisions of Sections 2.3,
2.5, 2.7, 4.1, 4.2, 4.3, 9.6, 9.10 and 13.5 hereof that shall survive until
such Securities shall mature and be paid.  Thereafter, Sections 9.6 and 13.5
shall survive.

SECTION 13.3.    DEPOSITED MONEYS TO BE HELD IN TRUST.

         All monies or Governmental Obligations deposited with the Trustee
pursuant to Sections 13.1 or 13.2 shall be held in trust and shall be available

Company acting as its own paying agent), to the holders of the particular
series of Securities for the payment or redemption of which such moneys or
Governmental Obligations have been deposited with the Trustee.

SECTION 13.4.    PAYMENT OF MONIES HELD BY PAYING AGENTS.

         In connection with the satisfaction and discharge of this Indenture
all moneys or Governmental Obligations then held by any paying agent under the

Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

SECTION 13.5.    REPAYMENT TO COMPANY.

or the Trustee, or then held by the Company in trust for payment of principal
of or premium or interest on the Securities of a particular series that are not
applied but remain unclaimed by the holders of such Securities for at least two
years after the date upon which the principal of (and premium, if any) or
interest on such Securities shall have respectively become due and payable,
shall be repaid to the Company, as the case may be, on May 31 of each year or
(if then held by the Company) shall be discharged from such trust; and
thereupon the paying agent and the Trustee shall be released from all further
liability with respect to such moneys or Governmental Obligations, and the
holder of any of the Securities entitled to receive such payment shall
thereafter, as an unsecured general creditor, look only to the Company or the
Guarantor for the payment thereof.

with the same force and effect





                                       45
<PAGE>   51

as if made on the nominal date of maturity or redemption, and no interest shall
accrue for the period after such nominal date.

SECTION 15.10.   COUNTERPARTS.

         This Indenture may be executed in any number of counterparts, each of
which shall be an original, but such counterparts shall together constitute but
one and the same instrument.

SECTION 15.11.   SEPARABILITY.

         In case any one or more of the provisions contained in this Indenture
or in the Securities of any series shall for any reason be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Indenture or of
such Securities, but this Indenture and such Securities shall be construed as
if such invalid or illegal or unenforceable provision had never been contained
herein or therein.

SECTION 15.12.   ASSIGNMENT.

         The Company will have the right at all times to assign any of its
respective rights or obligations under this Indenture to a direct or indirect
wholly-owned Subsidiary of the Company, provided that, in the event of any such
assignment, the Company, as the case may be, will remain liable for all such
obligations.  Subject to the foregoing, the Indenture is binding upon and
inures to the benefit of the parties thereto and their respective successors
and assigns.  This Indenture may not otherwise be assigned by the parties
thereto.

SECTION 15.13.   ACKNOWLEDGMENT OF RIGHTS.

         The Company acknowledges that, with respect to any Debentures held by
IBC Capital or a trustee of such trust, if the Property Trustee of such Trust
fails to enforce its rights under this Indenture as the holder of the series of
Debentures held as the assets of IBC Capital any holder of Preferred Securities
may institute legal proceedings directly against the Company to enforce such
Property Trustee's rights under this Indenture without first instituting any
legal proceedings against such Property Trustee or any other person or entity.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Company to pay
interest or principal on the applicable Series of Securities on the date such
interest or principal is otherwise payable (or in the case of redemption, on
the redemption date), the Company acknowledges that a holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the applicable Series of
Securities having a principal amount equal to the aggregate liquidation amount
of the Preferred





                                       46
<PAGE>   52

Securities of such holder on or after the respective due date specified in the
Applicable Series of Securities.

                                  ARTICLE XVI.
                          SUBORDINATION OF SECURITIES

SECTION 16.1.    AGREEMENT TO SUBORDINATE.

         The Company covenants and agrees, and each Holder of Debentures issued
hereunder by such Holder's acceptance thereof likewise covenants and agrees,
that all Debentures shall be issued subject to the provisions of this Article
XVI; and each Holder of a Debt Security, whether upon original issue or upon
transfer or assignment thereof, accepts and agrees to be bound by such
provisions.

         The payment by the Company of the principal of, premium, if any, and
interest on all Debentures issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
the prior payment in full of all Senior Debt, Subordinated Debt and Additional
Senior Obligations, whether outstanding at the date of this Indenture or
thereafter incurred.

         No provision of this Article XVI shall prevent the occurrence of any
default or Event of Default hereunder.

SECTION 16.2.    DEFAULT ON SENIOR DEBT, SUBORDINATED DEBT OR ADDITIONAL SENIOR
OBLIGATIONS.

         In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other payment due on any
Senior Debt, Subordinated Debt or Additional Senior Obligations of the Company,
as the case may be, or in the event that the maturity of any Senior Debt,
Subordinated Debt or Additional Senior Obligations of the Company, as the case
may be, has been accelerated because of a default, then, in either case, no
payment shall be made by the Company with respect to the principal (including
redemption and sinking fund payments) of, or premium, if any, or interest on
the Debentures.

         In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 16.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

SECTION 16.3.    LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Senior Indebtedness
of the Company shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any payment is made by the Company
on account of the principal (and premium, if any) or interest on the
Debentures; and upon any such dissolution or winding-up or liquidation or
reorganization, any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
which the Holders of the Debentures or the Trustee would be entitled to receive
from the Company, except for the provisions of this Article XVI, shall be paid
by the Company or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the Holders of
the Debentures or by the Trustee under the Indenture if received by them or it,
directly to the holders of Senior Indebtedness of the Company (pro rata to such
holders on the basis of the respective amounts of Senior Indebtedness held by
such holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Indebtedness may have been issued,
as their respective interests may appear, to the extent necessary to pay such
Senior Indebtedness in full, in money or money's worth, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to the Holders of
Debentures or to the Trustee.

         In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received by
the Trustee before all Senior Indebtedness of the Company is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of such Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, and their respective interests may appear, as calculated
by the Company, for application to the payment of all Senior Indebtedness of
the Company, as the case may be, remaining unpaid to the extent necessary to
pay such Senior Indebtedness in full in money in accordance with its terms,
after giving effect to any concurrent payment or distribution to or for the
benefit of the holders of such Senior Indebtedness.

         For purposes of this Article XVI, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this
Article XVI with respect to the Debentures to the payment of all Senior
Indebtedness of the Company, as the case may be, that may at the time be
outstanding, provided that (i) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment,
and (ii) the rights of the holders of such Senior Indebtedness are not, without
the consent of such holders, altered by such





                                       48
<PAGE>   54

reorganization or readjustment. The consolidation of the Company with, or the
merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon
the terms and conditions provided for in Article X of the Indenture shall not
be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 16.3 if such other corporation shall, as a part of
such consolidation, merger, conveyance or transfer, comply with the conditions
stated in Article X of the Indenture. Nothing in Section 16.2 or in this
Section 16.3 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 9.6 of the Indenture.

SECTION 16.4.    SUBROGATION.

         Subject to the payment in full of all Senior Indebtedness of the
Company, the rights of the Holders of the Debentures shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company, as the case may
be, applicable to such Senior Indebtedness until the principal of (and premium,
if any) and interest on the Debentures shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions to the holders of
such Senior Indebtedness of any cash, property or securities to which the
Holders of the Debentures or the Trustee would be entitled except for the
provisions of this Article XVI, and no payment over pursuant to the provisions
of this Article XVI to or for the benefit of the holders of such Senior
Indebtedness by Holders of the Debentures or the Trustee, shall, as between the
Company, its creditors other than Holders of Senior Indebtedness of the
Company, and the holders of the Debentures, be deemed to be a payment by the
Company to or on account of such Senior Indebtedness.  It is understood that
the provisions of this Article XVI are and are intended solely for the purposes
of defining the relative rights of the Holders of the Debentures, on the one
hand, and the holders of such Senior Indebtedness on the other hand.

         Nothing contained in this Article XIV or elsewhere in this Indenture
or in the Debentures is intended to or shall impair, as between the Company,
its creditors other than the holders of Senior Indebtedness of the Company, and
the Holders of the Debentures, the obligation of the Company, which is absolute
and unconditional, to pay to the Holders of the Debentures the principal of
(and premium, if any) and interest on the Debentures as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders of the Debentures and creditors
of the Company, as the case may be, other than the holders of Senior
Indebtedness of the Company, as the case may be, nor shall anything herein or
therein prevent the Trustee or the Holder of any Debt Security from exercising
all remedies otherwise permitted by applicable law upon default under the
Indenture, subject to the rights, if any, under this Article XVI of the holders
of such Senior Indebtedness in respect of cash, property or securities of the
Company, as the case may be, received upon the exercise of any such remedy.

         Upon any payment or distribution of assets of the Company referred to
in this Article XVI, the Trustee, subject to the provisions of Section 9.1 of
the Indenture, and the Holders of the Debentures shall be entitled to
conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee,





                                       49
<PAGE>   55

agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of the Debentures, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, as the case may be, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article XVI.

SECTION 16.5.    TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Holder of Debentures by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article XVI and appoints the Trustee such Holder's attorney-in-fact for
any and all such purposes.

SECTION 16.6.    NOTICE BY THE COMPANY.

         The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Debentures
pursuant to the provisions of this Article XVI.  Notwithstanding the provisions
of this Article XVI or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts that would prohibit
the making of any payment of monies to or by the Trustee in respect of the
Debentures pursuant to the provisions of this Article XVI, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder or holders of Senior Indebtedness or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 9.1 of the Indenture, shall be
entitled in all respects to assume that no such facts exist; provided, however,
that if the Trustee shall not have received the notice provided for in this
Section 8.6 at least two Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of (or premium, if any) or interest on
any Debenture), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive
such money and to apply the same to the purposes for which they were received,
and shall not be affected by any notice to the contrary that may be received by
it within two Business Days prior to such date.

         The Trustee, subject to the provisions of Section 9.1 of the
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company, as the case may be (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such
Senior Indebtedness or a trustee on behalf of any such holder or holders.  In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of such Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article XVI, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of such Senior
Indebtedness held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent to
the rights of such Person under this Article XVI, and, if such evidence is not
furnished, the Trustee may defer





                                       50
<PAGE>   56

any payment to such Person pending judicial determination as to the right of
such Person to receive such payment.

SECTION 16.7.    RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XIV in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article XIV, and no implied
covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture Indenture against the Trustee.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
such Senior Indebtedness and, subject to the provisions of Section 9.1 of the
Indenture, the Trustee shall not be liable to any holder of such Senior
Indebtedness if it shall pay over or deliver to Holders of Debentures, the
Company or any other Person money or assets to which any holder of such Senior
Indebtedness shall be entitled by virtue of this Article XVI or otherwise.

SECTION 16.8.    SUBORDINATION MAY NOT BE IMPAIRED.

         No right of any present or future holder of any Senior Indebtedness of
the Company to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company, as the case may be, or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Company, as the case
may be, with the terms, provisions and covenants of this Indenture, regardless
of any knowledge thereof that any such holder may have or otherwise be charged
with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from
time to time, without the consent of or notice to the Trustee or the Holders of
the Debentures, without incurring responsibility to the Holders of the
Debentures and without impairing or releasing the subordination provided in
this Article XVI or the obligations hereunder of the Holders of the Debentures
to the holders of such Senior Indebtedness, do any one or more of the
following:  (i) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend
or supplement in any manner such Senior Indebtedness or any instrument
evidencing the same or any agreement under which such Senior Indebtedness is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing such Senior Indebtedness; (iii)
release any Person liable in any manner for the collection of such Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against
the Company, as the case may be, and any other Person.

which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to, ______________ or
registered assigns, the principal sum of _____________ Dollars ($___________)

interest installment so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture, be paid to the
person in whose name this Debenture (or one or more Predecessor Securities, as
defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment, which shall be the close of
business on the business day next preceding such Interest Payment Date unless
otherwise provided in the Indenture.  Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to the
registered Holders on such regular record date and may be paid to the Person in
whose name this Debenture (or one or more Predecessor Securities) is registered
at the close of business on a special record date to be fixed by the Trustee
for the payment of such defaulted interest, notice whereof shall be given to
the registered Holders of this series of Debentures not less than 10 days prior
to such special record date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Debentures may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture.  The principal of
(and premium, if any) and the interest on this Debenture shall be payable at
the office or agency of the Trustee maintained for that purpose in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment
of interest may be made at the option of the Company by check mailed to the
registered Holder at such address as shall appear in the Security Register.
Notwithstanding the foregoing, so long as the Holder of this Debenture is the
Property Trustee, the payment of the principal of (and premium, if any) and
interest on this Debenture will be made at such place and to such account as
may be designated by the Institutional Trustee.

         The Stated Maturity may be shortened at any time by the Company to any
date not earlier than _________________, 2001, subject to the Company having
received prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies of the Federal Reserve.  Such date
may also be extended at any time at the election of the Company for one or more
periods, but in no event to a date later than ________________________, 2045,
subject to certain limitations described in the Indenture.

         The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Indebtedness, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto.  Each Holder
of this Debenture, by accepting the same, (a) agrees to and shall be bound by
such provisions, (b) authorizes and directs the Trustee on his or her behalf to
take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination so provided and (c) appoints the Trustee his or
her attorney-in-fact for any and all such purposes.  Each Holder hereof, by his
or her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder
of Senior Indebtedness, whether now outstanding or hereafter incurred, and
waives reliance by each such holder upon said provisions.

                         [FORM OF REVERSE OF DEBENTURE]

                     ______________% SUBORDINATED DEBENTURE
                                  (CONTINUED)

         This Debenture is one of the subordinated debentures of the Company
(herein sometimes referred to as the "Debentures"), specified in the Indenture,
all issued or to be issued in one or more series under and pursuant to an
Indenture dated as of _____________, 1996 (the "Indenture") duly executed and
delivered between the Company and State Street Bank and Trust Company, as
Trustee (the "Trustee"), to which Indenture reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Debentures.  The Debentures are limited in aggregate principal amount as
specified in the Indenture.

         Because of the occurrence and continuation of a Tax Event, in certain
circumstances, this Debenture may become due and payable at the principal
amount together with any interest accrued thereon (the "Redemption Price").
The Redemption Price shall be paid prior to 12:00 noon, Eastern Standard Time,
time, on the date of such redemption or at such earlier time as the Company
determines.  The Company shall have the right to redeem this Debenture at the
option of the Company, without premium or penalty, in whole or in part at any
time on or after ________, 2001 (an "Optional Redemption"), or at any time in
certain circumstances upon the occurrence of a Tax Event, at a redemption price
equal to 100% of the principal amount plus any accrued but unpaid interest, to
the date of such redemption (the "Optional Redemption Price").  Any redemption
pursuant to this paragraph will be made upon not less than 30 days nor more
than 60 days notice, at the Optional Redemption Price.  If the Debentures are
only partially redeemed by the Company pursuant to an Optional Redemption, the
Debentures will be redeemed pro rata or by lot or by any other method utilized
by the Trustee; provided that if, at the time of redemption, the Debentures are
registered as a Global Debenture, the Depositary shall determine the principal
amount of such Debentures held by each Debenture holder to be redeemed in
accordance with its procedures.

         In the event of redemption of this Debenture in part only, a new
Debenture or Debentures of this series for the unredeemed portion hereof will
be issued in the name of the Holder hereof upon the cancellation hereof.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Debentures may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the
Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Debentures of each series affected at the
time outstanding, as defined in the Indenture, to execute supplemental
indentures for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or of modifying in any manner





                                       57
<PAGE>   63

the rights of the Holders of the Debentures; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of the Debentures
except as provided in the Indenture, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce
any premium payable upon the redemption thereof, without the consent of the
Holder of each Debenture so affected, or (ii) reduce the aforesaid percentage
of Debentures, the Holders of which are required to consent to any such
supplemental indenture, without the consent of the Holders of each Debenture
then outstanding and affected thereby.  The Indenture also contains provisions
permitting the Holders of a majority in aggregate principal amount of the
Debentures at the time outstanding affected thereby, on behalf of all of the
Holders of the Debentures, to waive any past default in the performance of any
of the covenants contained in the Indenture, or established pursuant to the
Indenture, and its consequences, except a default in the payment of the
principal of or premium, if any, or interest on any of the Debentures of such
series.  Any such consent or waiver by the registered Holder of this Debenture
(unless revoked as provided in the Indenture) shall be conclusive and binding
upon such Holder and upon all future Holders and owners of this Debenture and
of any Debenture issued in exchange herefor or in place hereof (whether by
registration of transfer or otherwise), irrespective of whether or not any
notation of such consent or waiver is made upon this Debenture.

         No reference herein to the Indenture and no provision of this
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Debenture at the time and place and at
the rate and in the money herein prescribed.

         The Company shall have the right at any time during the term of the
Debentures and from time to time to extend the interest payment period of such
Debentures for up to 20 consecutive quarters (an "Extended Interest Payment
Period"), at the end of which period the Company shall pay all interest then
accrued and unpaid (together with interest thereon at the rate specified for
the Debentures to the extent that payment of such interest is enforceable under
applicable law).  Before the termination of any such Extended Interest Payment
Period, the Company may further extend such Extended Interest Payment Period,
provided that such Extended Interest Payment Period together with all such
further extensions thereof shall not exceed 20 consecutive quarters.  At the
termination of any such Extended Interest Payment Period and upon the payment
of all accrued and unpaid interest and any additional amounts then due, the
Company may commence a new Extended Interest Payment Period.

         As provided in the Indenture and subject to certain limitations
therein set forth, this Debenture is transferable by the registered Holder
hereof on the Security Register of the Company, upon surrender of this
Debenture for registration of transfer at the office or agency of the Trustee
in _________________ accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company or the Trustee duly executed by
the registered Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Debentures of authorized denominations and for the
same aggregate principal amount and series will be issued to the designated
transferee or transferees.  No service charge will be made for any such
transfer, but the





                                       58
<PAGE>   64

Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

         Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any paying agent and the Security
Registrar may deem and treat the registered holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and notwithstanding any
notice of ownership or writing hereon made by anyone other than the Security
Registrar) for the purpose of receiving payment of or on account of the
principal hereof and premium, if any, and interest due hereon and for all other
purposes, and neither the Company nor the Trustee nor any paying agent nor any
Security Registrar shall be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issuance hereof,
expressly waived and released.

         The Debentures are issuable only in registered form without coupons in
denominations of $25 and any integral multiple thereof.  This Global Debenture
is exchangeable for Debentures in definitive form only under certain limited
circumstances set forth in the Indenture.  Debentures of this series so issued
are issuable only in registered form without coupons in denominations of $25
and any integral multiple thereof.

otherwise.

         4.      The Depositor and the Trustees hereby authorize and direct the

rules and regulations of the Commission, an Exchange or state securities or
blue sky laws, to be executed on behalf of the Trust by one or more of the
Trustees, each of the Trustees, in its or his capacity as a Trustee of the

         6.      The number of Trustees initially shall be four (4) and
thereafter the number of Trustees shall be such number as shall be fixed from
time to time by a written instrument signed by the Depositor which may increase
or decrease the number of Trustees; provided, however, that to the extent
required by the Business Trust Act, one Trustee shall either be a natural
person who is a resident of the State of Delaware or, if not a natural person,
an entity which has its principal place of business in the State of Delaware
and otherwise meets the requirements of applicable Delaware law. Subject to the
foregoing, the Depositor is entitled to appoint or remove without cause any
Trustee at any time.  The Trustees may resign upon thirty (30) days' prior

                           DISTRIBUTIONS; REDEMPTION

     SECTION 401.  DISTRIBUTIONS.

     (a) Distributions on the Trust Securities shall be cumulative, and will
accumulate whether or not there are funds of the Trust available for the payment
of Distributions.  Distributions shall accumulate from , 1996, and, except
during any Extension Period with respect to the Debentures, shall be payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of each
year, commencing on __________, 1997.  If any date on which a Distribution is
otherwise payable on the Trust Securities is not a Business Day, then the
payment of such Distribution shall be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that, if such Business Day is in the next succeeding calendar
year, payment of such Distribution shall be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on such
date (each date on which distributions are payable in accordance with this
Section 401(a) a "Distribution Date").

     (b) The Trust Securities represent undivided beneficial interests in the
Trust Property, and, as a practical matter, the Distributions on the Trust
Securities shall be payable at a rate of                % per annum of the
Liquidation Amount of the Trust Securities.  The amount of Distributions payable
for any full period shall be computed on the basis of a 360-day year of twelve
30-day months.  The amount of Distributions for any partial period shall be
computed on the basis of the number of days elapsed in a 360-day year of twelve
30 day months.  During any Extension Period with respect to the Debentures,
Distributions on the Preferred Securities will be deferred for 



                                       16
<PAGE>   22



a period equal to the Extension Period.  The amount of Distributions payable for
any period shall include the Additional Amounts, if any.

     (c)  Distributions on the Trust Securities shall be made by the Property
Trustee solely from the Payment Account and shall be payable on each
Distribution Date only to the extent that the Trust has funds then on hand and
immediately available in the Payment Account for the payment of such
Distributions.

     (d)  Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
one Business Day prior to such Distribution Date; provided, however, that in the
event that the Preferred Securities do not remain in book-entry-only form, the
relevant record date shall be the date 15 days prior to the relevant
Distribution Date.

     SECTION 402.  REDEMPTION.

     (a)  on each Debenture Redemption Date and on the stated maturity of the
Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

     (b)  Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Security Register.  The Property
Trustee shall have no responsibility for the accuracy of any CUSIP number
contained in such notice.  All notices of redemption shall state:

          (i) the Redemption Date;

          (ii) the Redemption Price;

          (iii) the CUSIP number;

          (iv) if less than all the Outstanding Trust Securities are to be
redeemed, the identification and the aggregate Liquidation Amount of the
particular Trust Securities to be redeemed; and

          (v) that on the Redemption Date the Redemption Price will become due
and payable upon each such Trust Security to be redeemed and that distributions
thereon will cease to accumulate on and after said date.

     (c) The Trust Securities redeemed on each Redemption Date shall be redeemed
at the Redemption Price with the proceeds from the contemporaneous redemption of
Debentures.  Redemptions of the Trust Securities shall be made and the
Redemption Price shall be payable on each 


                                       17
<PAGE>   23



Redemption Date only to the extent that the Trust has immediately available
funds then on hand and available in the Payment Account for the payment of such
Redemption Price.

     (d) If the Property Trustee gives a notice of redemption in respect of any
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 402(c), the Property Trustee will, so long as the
Preferred Securities are in book-entry-only form, deposit with the Clearing
Agency for the Preferred Securities funds sufficient to pay the applicable
Redemption Price and will give such Clearing Agency irrevocable instructions and
authority to pay the Redemption Price to the holders thereof.  If the Preferred
Securities are no longer in book-entry-only form, the Property Trustee, subject
to Section 402(c), will deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and will give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of' their Preferred Securities Certificates. Notwithstanding the
foregoing, Distributions payable on or prior to the Redemption Date for any
Trust Securities called for redemption shall be payable to the Holders of such
Trust Securities as they appear on the Register for the Trust Securities on the
relevant record dates for the related Distribution Dates.  If notice of
redemption shall have been given and funds deposited as required, then upon the
date of such deposit, all rights of Securityholders holding Trust Securities so
called for redemption will cease, except the right of such Securityholders to
receive the Redemption Price and any Distribution payable on or prior to the
Redemption Date, but without interest, and such Securities will cease to be
Outstanding.  In the event that any date on which any Redemption Price is
payable is not a Business Day, then payment of the Redemption Price payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day falls in the next calendar year, such payment will be
made on the immediately precedig Business Day, in each case, with the same force
and effect as if made on such date.  In the event that payment of the Redemption
Price in respect of any Trust Securities called for redemption is improperly
withheld or refused and not paid either by the Trust or by the Depositor
pursuant to the Guarantee, Distributions on such Trust Securities will continue
to accumulate, at the then applicable rate, from the Redemption Date originally
established by the Trust for such Trust Securities to the date such Redemption
Price is actually paid, in which case the actual payment date will be the date
fixed for redemption for purposes of calculating the Redemption Price.

     (e) Payment of the Redemption Price on the Trust Securities shall be made
to the record holders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which shall be one Business Day
prior to the relevant Redemption Date; provided, however, that in the event that
the Preferred Securities do not remain in book-entry-only form, the relevant
record date shall be the date fifteen days prior to the relevant Redemption
Date.

     (f) Subject to Section 403(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities.  The particular Preferred Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Property Trustee from 


                                       18
<PAGE>   24



the outstanding Preferred Securities not previously called for redemption, by
such method (including, without limitation, by lot) as the Property Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to $25 or an integral multiple of $25 in excess
thereof) of the Liquidation Amount of Preferred Securities of a denomination
larger than $25.  The Property Trustee shall promptly notify the Security
Registrar in writing of the Preferred Securities selected for redemption and, in
the case of any Preferred Securities selected for partial redemption, the
Liquidation Amount thereof to be redeemed.  For all purposes of this Trust
Agreement, unless the context otherwise requires, all provisions relating to the
redemption of Preferred Securities shall relate, in the case of any Preferred
Securities redeemed or to be redeemed only in part, to the portion of the
Liquidation Amount of Preferred Securities which has been or is to be redeemed.

     SECTION 403. SUBORDINATION OF COMMON SECURITIES.

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 402(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities then called for
redemption, shall have been made or provided for, and all funds immediately
available to the Property Trustee shall first be applied to the payment in full
in cash of all Distributions (including Additional Amounts, if applicable) on,
or the Redemption Price of, Preferred Securities then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from a
Debenture Event of Default, the Holder of Common Securities will be deemed to
have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities shall have been cured, waived or otherwise
eliminated.  Until any such Event of Default under this Trust Agreement with
respect to the Preferred Securities shall have been so cured, waived or
otherwise eliminated, the Property Trustee shall act solely on behalf of the
Holders of the Preferred Securities and not the Holder of the Common Securities,
and only the Holders of the Preferred Securities will have the right to direct
the Property Trustee to act on their behalf.

of all such returns and reports promptly after such filing or furnishing. The
Property Trustee shall comply with United States federal withholding and backup
withholding tax laws and information reporting requirements with respect to any
payments to Securityholders under the Trust Securities.

     SECTION 406.  PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.

of whatsoever nature (other than withholding taxes) imposed on the Trust by the
United States or any other taxing authority.

     SECTION 407.  PAYMENTS UNDER INDENTURE.

     Any amount payable hereunder to any Holder of Preferred Securities shall be

notwithstanding that such individuals or any of them shall have ceased to be so

Assistant Treasurer without further corporate action by the Depositor, in

     SECTION 504.  REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED
     SECURITIES CERTIFICATES.

     The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 508, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (herein referred to as the "Securities

provide for the registration of Preferred Securities Certificates and Common
Securities Certificates (subject to Section 510 in the case of the Common
Securities Certificates) and registration of transfers and exchanges of
Preferred Securities Certificates as herein provided.  The Property Trustee
shall be the initial Securities Registrar.

     Upon surrender for registration of transfer of any Preferred Securities

Securities during a period beginning at the opening of business 15 calendar days
before the date of mailing of a notice of redemption of any Preferred Securities
called for redemption and ending at the close of business on the day of such
mailing or (ii) register the transfer of or exchange any Preferred Securities so
selected for redemption, in whole or in part, except the unredeemed portion of
any such Preferred Securities being redeemed in part.

     No service charge shall be made for any registration of transfer or
exchange of Preferred securities Certificates, but the Securities Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

     SECTION 505.  MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
     CERTIFICATES.

the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction, loss or theft of any Trust Securities
Certificate and (b) there shall be delivered to the Securities Registrar and the
Administrative Trustees such security or indemnity as may be required by them to

execute and make available for delivery, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust
Securities Certificate of like class, tenor and denomination.  In connection
with the issuance of any new Trust Securities Certificate under this Section,
the Administrative Trustees or the Securities Registrar may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith.  Any duplicate Trust Securities Certificate

                                       22
<PAGE>   28

     The Trustees, the Paying Agent and the Securities Registrar shall treat the
Person in whose name any Trust Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Securities Certificate for the
purpose of receiving Distributions and for all other purposes whatsoever, and
neither the Trustees nor the Securities Registrar shall be bound by any notice
to the contrary.

     SECTION 507.  ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

     At any time when the Property Trustee is not also acting as the Securities
Registrar, the Administrative Trustees or the Depositor shall furnish or cause
to be furnished to the Property Trustee (a) semi-annually on or before January
15 and July 15 in each year, a list, in such form as the Property Trustee may
reasonably require, of the names and addresses of the Securityholders as of the
most recent Record Date and (b) promptly after receipt by any Administrative
Trustee or the Depositor of a request therefor from the Property Trustee in
order to enable the Property Trustee to discharge its obligations under this
Trust Agreement, in each case to the extent such information is in the
possession or control of the Administrative Trustees or the Depositor and is not
identical to a previously supplied list or has not otherwise been received by
the Property Trustee in its capacity as Securities Registrar.  The rights of
Securityholders to communicate with other Securityholders with respect to their
rights under this Trust Agreement or under the Trust Securities, and the
corresponding rights of the Trustee shall be as provided in the Trust Indenture
Act.  Each Holder, by receiving and holding a Trust Securities Certificate, and
each owner shall be deemed to have agreed not to hold the Depositor, the
Property Trustee or the Administrative Trustees accountable by reason of the
disclosure of its name and address, regardless of the source from which such
information was derived.

     SECTION 508.  MAINTENANCE OF OFFICE OR AGENCY.

     The Administrative Trustees shall maintain in The City of New York, an
office or offices or agency or agencies where Preferred Securities Certificates
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Trustees in respect of the Trust Securities
Certificates may be served.  The Administrative Trustees initially designate the
principal corporate trust office of the Property Trustee, [insert address], as
the principal corporate trust office for such purposes.  The Administrative
Trustees shall give prompt written notice to the Depositor and to the
Securityholders of any change in the location of the Securities Register or any
such office or agency.

     SECTION 509.  APPOINTMENT OF PAYING AGENT.

     The Paying Agent shall make distributions to Securityholders from the
Payment Account and shall report the amounts of such distributions to the
Property Trustee and the Administrative Trustees.  Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the Distributions referred to above.  The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole 



                                       23
<PAGE>   29



discretion that the Paying Agent shall have failed to perform its obligations
under this Trust Agreement in any material respect.  The Paying Agent shall
initially be the Property Trustee, and any co-paying agent chosen by the
Property Trustee, and acceptable to the Administrative Trustees and the
Depositor.  Any Person acting as Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Administrative Trustees, the
Property Trustee and the Depositor.  In the event that the Property Trustee
shall no longer be the Paying Agent or a successor Paying Agent shall resign or
its authority to act be revoked, the Administrative Trustees shall appoint a
successor that is acceptable to the Property Trustee and the Depositor to act as
Paying Agent (which shall be a bank or trust company). The Administrative
Trustees shall cause such successor Paying Agent or any additional Paying Agent
appointed by the Administrative Trustees to execute and deliver to the Trustees
an instrument in which such successor Paying Agent or additional Paying Agent
shall agree with the Trustees that as Paying Agent, such successor Paying Agent
or additional Paying Agent will hold all sums, if any, held by it for payment to
the Securityholders in trust for the benefit of the Securityholders entitled
thereto until such sums shall be paid to such Securityholders.  The Paying Agent
shall return all unclaimed funds to the Property Trustee and upon removal of a
Paying Agent such Paying Agent shall also return all funds in its possession to

other paying agent appointed hereunder.  Any reference in this Agreement to the
Paying Agent shall include any co-paying agent unless the context requires
otherwise.

     SECTION 510.  OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

     On the Closing Date, the Depositor shall acquire and retain beneficial and
record ownership of the Common Securities.  To the fullest extent permitted by
law, any attempted transfer of the Common Securities (other than a transfer in
connection with a merger or consolidation of the Depositor into another
corporation pursuant to Section 10.01 of the Indenture) shall be void.  The
Administrative Trustees shall cause each common Securities Certificate issued to
the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT
TRANSFERABLE".

     SECTION 511.  BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be

Clearing Agency, by, or on behalf of, the Trust.  Such Book-Entry Preferred
Securities Certificate or Certificates shall initially be registered on the
Securities Register in the name of Cede & Co., the nominee of the initial
Clearing Agency, and no beneficial owner will receive a Definitive Preferred
Securities Certificate representing such beneficial owner's interest in such
Preferred Securities, except as provided in section 513, unless and until
Definitive Preferred Securities Certificates have been issued to beneficial
owners pursuant to Section 513:

          (i) the provisions of this Section 511(a) shall be in full force and
effect;

          (ii) the Securities Registrar, the Paying Agent and the Trustees shall
be entitled to deal with the Clearing Agency for all purposes of this Trust
Agreement relating to the Book Entry Preferred Securities Certificates
(including the payment of the Liquidation Amount of and Distributions on the
Book-Entry Preferred Securities) as the sole Holder of Book-Entry Preferred
Securities and shall have no obligations to the Owners thereof;

          (iii) to the extent that the provisions of this Section 511 conflict
with any other provisions of this Trust Agreement, the provisions of this
Section 511 shall control; and

          (iv) the rights of the Owners of the Book-Entry Preferred Securities
Certificates shall be exercised only through the Clearing Agency and shall be
limited to those established by law and agreements between such Owners and the
Clearing Agency and/or the Clearing Agency Participants.  Pursuant to the
Certificate Depository Agreement, unless and until Definitive Preferred
Securities Certificates are issued pursuant to Section 513, the initial Clearing
Agency will make book-entry transfers among the Clearing Agency Participants and
receive and transmit payments on the Preferred Securities to such Clearing
Agency Participants.  Any Clearing Agency designated pursuant hereto will not be
deemed an agent of the Trustees for any purpose.

     (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

     SECTION 512.  NOTICES TO CLEARING AGENCY.

required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
513, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.


     SECTION 513.  DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

     If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Preferred Securities Certificates, and the Depositor is
unable to locate a qualified successor, (b) the Depositor at its option advises
the Trustees in writing that it elects to terminate the book-entry system
through the Clearing Agency, or (c) after the occurrence of a Debenture Event of
Default, owners of Preferred Securities Certificates representing beneficial
interests aggregating at least a majority of the Liquidation Amount advise the
Property Trustee in writing that the continuation of a book-entry system through
the Clearing Agency is no longer in the best interests of the owners of
Preferred Securities Certificates, then the Property Trustee shall notify the
Clearing Agency, and the Clearing Agency shall notify all Owners of Preferred
Securities Certificates, of the occurrence of any such event and of the
availability

of the Definitive Preferred Securities Certificates to owners of such class or
classes, as applicable, requesting the same.  Upon surrender to the Property
Trustee of the typewritten Preferred Securities certificate or Certificates
representing the Book-Entry Preferred Securities Certificates by the Clearing
Agency, accompanied by registration instructions, the Administrative Trustees,
or any one of them, shall execute the Definitive Preferred Securities
Certificates in accordance with the instructions of the Clearing Agency.
Neither the Securities Registrar nor the Trustees shall be liable for any delay
in delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions.  Upon the issuance of Definitive
Preferred Securities Certificates, the Trustees shall recognize the Holders of
the Definitive Preferred Securities Certificates as Securityholders.  The
Definitive Preferred Securities Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

     SECTION 514.  RIGHTS OF SECURITYHOLDERS.

     (a)  The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 209, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement.  The Trust
Securities shall have no preemptive or similar rights.  When issued and
delivered to Holders of the Preferred Securities against payment of the purchase
price therefor, the Preferred Securities will be fully paid and nonassessable
interests in the Trust.  The Holders of the Preferred Securities, in their
capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

     (b)  For so long as any Preferred Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Preferred Securities then
Outstanding shall have such right by a notice in writing to the Depositor and
the Debenture Trustee; and upon any such declaration such principal amount of
and the accrued interest on all of the Debentures shall become immediately due
and payable, provided that the payment of principal and interest on such
Debentures shall remain subordinated to the extent provided in the Indenture.

     (c)  For so long as any Preferred Securities remain outstanding, if, upon a
Debenture Event of Default arising from the failure to pay interest or 
principal on the Debentures, the Holders of any Preferred Securities then 
Outstanding shall, to the fullest extent permitted by law, have the right to 
directly institute proceedings for enforcement of payment to such Holders of 
principal of or interest 



                                       26

on the Debentures having a principal amount equal to the Liquidation Amount of
the Preferred Securities of such Holders.

                   ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

SECTION 601.  LIMITATIONS ON VOTING RIGHTS.

     (a) Except as provided in this Section, in Sections 514, 810 and 1002 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Article Six of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of at least a majority in Liquidation Amount of all
outstanding Preferred Securities; provided, however, that where a consent under
the Indenture would require the consent of each Holder of Outstanding Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior written consent of each holder of Preferred Securities.  The Trustees
shall not revoke any action previously authorized or approved by a vote of the
Holders of the Outstanding Preferred Securities, except by a subsequent vote of
the Holders of the outstanding Preferred Securities.  The Property Trustee shall
notify each Holder of the Outstanding Preferred Securities of any notice of
default received from the Debenture Trustee with respect to the Debentures.  In
addition to obtaining the foregoing approvals of the Holders of the Preferred
Securities, prior to taking any of the foregoing actions, the Trustees shall, at
the expense of the Depositor, obtain an opinion of Counsel experienced in such
matters to the effect that the Trust will continue to be classified as a grantor
trust and not as an association taxable as a corporation for United States
federal income tax purposes on account of such action.


     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in 




                                       27
<PAGE>   33

Liquidation Amount of the Outstanding Preferred Securities.  No amendment to
this Trust Agreement may be made if, as a result of such amendment, the Trust
would cease to be classified as a grantor trust or would be classified as an
association taxable as a corporation for United States federal income tax
purposes.

     SECTION 602.  NOTICE OF MEETINGS.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 1008 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting.  At any such meeting, any business properly before the meeting may be
so considered whether or not stated in the notice of the meeting.  Any adjourned
meeting may be held as adjourned without further notice.

     SECTION 603.  MEETINGS OF PREFERRED SECURITYHOLDERS.

     No annual meeting of Securityholders is required to be held.  The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
25% of the Outstanding Preferred Securities (based upon their aggregate
Liquidation Amount) and the Administrative Trustees or the Property Trustee may,
at any time in their discretion, call a meeting of Preferred Securityholders to
vote on any matters as to which the Preferred Securityholders are entitled to
vote.

     Preferred Securityholders of record of 50% of the Outstanding Preferred
Securities (based upon their aggregate Liquidation Amount), present in person or
by proxy, shall constitute a quorum at any meeting of Securityholders.

     If a quorum is present at a meeting, an affirmative vote by the Preferred
Securityholders of record present, in person or by proxy, holding more than a
majority of the Preferred Securities (based upon their aggregate Liquidation
Amount) held by the Preferred Securityholders of record present, either in
person or by proxy, at such meeting shall constitute the action of the
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

     SECTION 604.  VOTING RIGHTS.

     Securityholders shall be entitled to one vote for each $25 of Liquidation
Amount represented by their Trust Securities in respect of any matter as to
which such Securityholders are entitled to vote.

     SECTION 605.  PROXIES, ETC.

     At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy, shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the




                                       28
<PAGE>   34


Administrative Trustees may direct, for verification prior to the time at which
such vote shall be taken.  When Trust Securities are held jointly by several
persons, any one of them may vote at any meeting in person or by proxy in
respect of such Trust Securities, but if more than one of them shall be present
at such meeting in person or by proxy, and such joint owners or their proxies
so present disagree as to any vote to be cast, such vote shall not be received
in respect of such Trust securities.  A proxy purporting to be executed by or
on behalf of a Securityholder shall be deemed valid unless challenged at or
prior to its exercise, and, the burden of proving invalidity shall rest on the
challenger.  No proxy shall be valid more than three years after its date of
execution.

     SECTION 606.  SECURITYHOLDER ACTION BY WRITTEN CONSENT.

     Any action which may be taken by Securityholders at a meeting may be taken
without a meeting if Securityholders holding more than a majority of all
Outstanding Trust Securities (based upon their aggregate Liquidation Amount)
entitled to vote in respect of such action (or such larger proportion thereof
as shall be required by any express provision of this Trust Agreement) shall
consent to the action in writing (based upon their aggregate Liquidation
Amount).

     SECTION 607.  RECORD DATE FOR VOTING AND OTHER PURPOSES.

     For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate
in any Distribution on the Trust Securities in respect of which a record date
is not otherwise provided for in this Trust Agreement, or for the purpose of
any other action, the Administrative Trustees may from time to time fix a date,
not more than 90 days prior to the date of any meeting of Securityholders or
the payment of Distribution or other action, as the case may be, as a record
date for the determination of the identity of the Securityholders of record for
such purposes.

     SECTION 608.  ACTS OF SECURITYHOLDERS.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Trust Agreement to be given, made or
taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee.
Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders
or Owners signing such instrument or instruments.  Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Trust Agreement and (subject to Section 801) conclusive
in favor of the Trustees, if made in the manner provided in this Section.


     The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other 



                                      29
<PAGE>   35



officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing such instrument or writing acknowledged to him the
execution thereof.  Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also
constitute sufficient proof of his authority.  The fact and date of the
execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which any Trustee
receiving the same deems sufficient.

     The ownership of Preferred Securities shall be proved by the Securities
Register.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

     Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do
so with regard to all or any part of the Liquidation Amount of such Trust
Security or by one or more duly appointed agents each of which may do so
pursuant to such appointment with regard to all or any part of such liquidation
amount.

     A Securityholder may institute a legal proceeding directly against the
Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined
in the Guarantee), the Trust or any Person.

     SECTION 609.  INSPECTION OF RECORDS.

     Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by
Securityholders during normal business hours for any purpose reasonably related
to such Securityholder's interest as a Securityholder.

                                  ARTICLE VIII
                                  THE TRUSTEES

     SECTION 801.  CERTAIN DUTIES AND RESPONSIBILITIES.

          (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.  No Administrative Trustee nor the Delaware Trustee shall be liable for its
act or omissions hereunder except as a result of its own gross negligence or
willful misconduct.  The Property Trustee's liability shall be determined under
the Trust Indenture Act.  Whether or not therein expressly so provided, every 
provision of this Trust Agreement relating to the conduct or affecting the 
liability of or affording protection to the Trustees shall be subject to the 
provisions of this Section.  To the extent that, at law or in equity, the
Delaware Trustee an Administrative Trustee has duties (including fiduciary 
duties) and liabilities relating thereto to the Trust or to the 
Securityholders, the Delaware Trustee such Administrative Trustee shall not be
liable to the Trust or to any Securityholder for such Trustee's good faith 
reliance on the provisions of this Trust Agreement.  The provisions of this 
Trust Agreement, to the extent that they restrict the duties and liabilities of
the Delaware Trustee the Administrative Trustees otherwise existing at law or 
in equity, are agreed by the Depositor and the Securityholders to replace such
other duties and liabilities of the Administrative Trustees.

          (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the revenue and proceeds
from the Trust Property and only to the extent that there shall be sufficient
revenue or proceeds from the Trust Property to enable the Property Trustee or a
Paying Agent to make payments in accordance with the terms hereof.  Each
Securityholder, by its acceptance of a Trust Security, agrees that it will look
solely to the revenue and proceeds from the Trust Property to the extent legally
available for distribution to it as herein provided and that the Trustees are
not personally liable to it for any amount distributable in respect of any Trust
Security or for any other liability in respect of any Trust Security.  This
Section 801(b) does not limit the liability of the Trustees expressly set forth
elsewhere in this Trust Agreement or, in the case of the Property Trustee, in
the Trust Indenture Act.

          (c) No provision of this Trust Agreement shall be construed to relieve
the Property Trustee from liability for its own negligent action, its own

of conducting any proceeding for any remedy available to the Property Trustee,
or exercising any trust or power conferred upon the Property Trustee under this
Trust Agreement;


               (iii) the Property Trustee's sole duty with respect to the
custody, safe keeping and physical preservation of the Debentures and the

          (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property

counsel may be counsel to the Depositor or any of its Affiliates) and the advice
of such counsel shall be full and complete authorization and protection in

enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Securities
which instructions may only be given by the Holders of the same proportion in
Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action, (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received, and (iii) shall
be protected in acting in accordance with such instructions; and

          (k) except as otherwise expressly provided by this Trust Agreement,

or obligation conferred or imposed on it, in any jurisdiction in which it shall
be illegal, or in which the Property Trustee shall be unqualified or incompetent
in accordance with applicable law, to perform any such act or acts, or to

Agreement.

     SECTION 809.  CO-TRUSTEES AND SEPARATE TRUSTEE.

     Unless an Event of Default shall have occurred and be continuing, at any
time or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Depositor shall have power to appoint, and upon the
written request of the Property Trustee, the Depositor shall for such purpose
join with the Property Trustee in the execution, delivery and performance of all
instruments and agreements necessary or proper to appoint, one or more Persons
approved by the Property Trustee either to act as co-trustee, jointly with the
Property Trustee, of all or any part of such Trust Property, or to the extent
required by law to act as separate trustee of any such property, in either case
with such powers as may be provided in the instrument of appointment, and to
vest in such Person or Persons in the capacity aforesaid, any property, title,
right or power deemed necessary or desirable, subject to the other provisions of
this Section.  If the Depositor does not join in such appointment within 15 days

co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, 



                                       39
<PAGE>   45

title, right, or power, any and all such instruments shall, on request, be
executed, acknowledged, and delivered by the Depositor.

     Every co-trustee or separate trustee shall, to the extent permitted by law,
but to such extent only, be appointed subject to the following terms, namely:

          (a) The Trust Securities shall be executed and delivered and all
rights, powers, duties and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

          (b) The rights, powers, duties and obligations hereby conferred or
imposed upon the Property Trustee in respect of any property covered by such
appointment shall be conferred or imposed upon and exercised or performed by the
Property Trustee or by the Property Trustee and such co-trustee or separate
trustee jointly, as shall be provided in the instrument appointing such
co-trustee or separate trustee, except to the extent that under any law of any
jurisdiction in which any particular act is to be performed, the Property
Trustee shall be incompetent or unqualified to perform such act, in which event
such rights, powers, duties and obligations shall be exercised and performed by
such co-trustee or separate trustee.


          (c) The Property Trustee at any time, by an instrument in writing
executed by it, with the written concurrence of the Depositor, may accept the
resignation of or remove any co-trustee or separate trustee appointed under this
Section, and, in case a Debenture Event of Default has occurred and is
continuing, the Property Trustee shall have power to accept the resignation of,
or remove, any such co-trustee or separate trustee without the concurrence of
the Depositor.  Upon the written request of the Property Trustee, the Depositor
shall join with the Property Trustee in the execution, delivery and performance
of all instruments and agreements necessary or proper to effectuate such
resignation or removal.  A successor to any co-trustee or separate trustee so
resigned or removed may be appointed in the manner provided in this Section 809.

          (d) No co-trustee or separate trustee hereunder shall be personally
liable by reason of any act or omission of the Property Trustee or any other
trustee hereunder.

          (e) The Property Trustee shall not be liable by reason of any act of a
co-trustee or separate trustee.

          (f) Any Act of Holders delivered to the Property Trustee shall be
deemed to have been delivered to each such co-trustee and separate trustee.

     SECTION 810.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.



                                       40
<PAGE>   46



     No resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 811.

     Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time with respect to the Trust Securities by giving written notice
thereof to the Securityholders.  If the instrument of acceptance by the
successor Trustee required by Section 811 shall not have been delivered to the
Relevant Trustee within 30 days after the giving of such notice of resignation,
the Relevant Trustee may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee with
respect to the Trust Securities.

     Unless a Debenture Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by Act of the Common Securityholder.  If
a Debenture Event of Default shall have occurred and be continuing, the Property
Trustee or the Delaware Trustee, or both of them, may be removed at such time by
Act of the Holders of a majority in Liquidation Amount of the Preferred
Securities, delivered to the Relevant Trustee (in its individual capacity and on
behalf of the Trust).  An Administrative Trustee may be removed by the Common
Securityholder at any time.

     If any Trustee shall resign, be removed or become incapable of acting as
Trustee, or if a vacancy shall occur in the office of any Trustee for any cause,
at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees with respect to the Trust Securities and the Trust, and the successor
Trustee shall comply with the applicable requirements of Section 811. If the
Property Trustee or the Delaware Trustee shall resign, be removed or become
incapable of continuing to act as the Property Trustee or the Delaware Trustee,
as the case may be, at a time when a Debenture Event of Default shall have
occurred and is continuing, the Preferred Securityholders, by Act of the
Securityholders of a majority in Liquidation Amount of the Preferred Securities
then Outstanding delivered to the retiring Relevant Trustee, shall promptly
appoint a successor Relevant Trustee or Trustees with respect to the Trust
Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements of Section 811.  If an Administrative Trustee shall
resign, be removed or become incapable of acting as Administrative Trustee, at a
time when a Debenture Event of Default shall have occurred and be continuing,
the Common Securityholder, by Act of the Common Securityholder delivered to an
Administrative Trustee, shall promptly appoint a successor Administrative
Trustee or Administrative Trustees with respect to the Trust Securities and the
Trust, and such successor Administrative Trustee or Administrative Trustees
shall comply with the applicable requirements of Section 811.  If no successor
Relevant Trustee with respect to the Trust Securities shall have been so
appointed by the Common Securityholder or the Preferred Securityholders and
accepted appointment in the manner required by Section 811, any Securityholder
who has been a Securityholder of Trust Securitie on behalf of himself and all
others similarly situated may petition a court of competent jurisdiction for 
the appointment Trustee with respect to the Trust Securities.



                                       41
<PAGE>   47


     The Property Trustee shall give notice of each resignation and each removal
of a Trustee and each appointment of a successor Trustee to all Securityholders
in the manner provided in Section 1008 and shall give notice to the Depositor.
Each notice shall include the name of the successor Relevant Trustee and the
address of its Corporate Trust office if it is the Property Trustee.

     Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees set forth in Section 807).

     SECTION 811.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     In case of the appointment hereunder of a successor Relevant Trustee with
respect to the Trust Securities and the Trust, the retiring Relevant Trustee and
each successor Relevant Trustee with respect to the Trust Securities shall
execute and deliver an instrument hereto wherein each successor Relevant Trustee
shall accept such appointment and which shall contain such provisions as shall
be necessary or desirable to transfer and confirm to, and to vest in, each
successor Relevant Trustee all the rights, powers, trusts and duties of the
retiring Relevant Trustee with respect to the Trust Securities and the Trust 
and upon the execution and delivery of such instrument the resignation or 
removal of the retiring Relevant Trustee shall become effective to the extent 
provided therein and each such successor Relevant Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, 
trusts and duties of the retiring Relevant Trustee with respect to the Trust 
Securities and the Trust; but, on request of the Trust or any successor 
Relevant Trustee such retiring Relevant Trustee shall duly assign, transfer and
deliver to such successor Relevant Trustee all Trust Property, all proceeds 
thereof and money held by such retiring Relevant Trustee hereunder with 
respect to the Trust Securities and the Trust.

     Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the immediately preceding paragraph, as the case may be.

     No successor Relevant Trustee shall accept its appointment unless at the
time of such acceptance such successor Relevant Trustee shall be qualified and
eligible under this Article.

     SECTION 812.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which such Relevant Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of such Relevant Trustee, shall be the successor of such Relevant Trustee
hereunder, provided such Person shall be otherwise qualified and eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.

     SECTION 813.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR TRUST.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Depositor or the Trust (or any other obligor upon the
Debentures or the Trust Securities) , the Property Trustee or the Delaware
Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor).

     SECTION 814.  REPORTS BY PROPERTY TRUSTEE.

          (a) Not later than July 15 of each year commencing with
______________, 199___, the Property Trustee shall transmit to all
Securityholders in accordance with Section 1008, and to the Depositor, a brief
report dated as of such December 31 with respect to:

               (i) its eligibility under Section 807 or, in lieu thereof, if to
the best of its knowledge it has continued to be eligible under said Section, a

               (ii) any change in the property and funds in its possession as
Property Trustee since the date of its last report and any action taken by the
Property Trustee in the performance of its duties hereunder which it has not
previously reported and which in its opinion materially affects the Trust
Securities.


          (b) In addition the Property Trustee shall transmit to Securityholders
such reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

          (c) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Property Trustee with each national securities
exchange or other organization upon which the Trust Securities are listed, with
the Commission and with the Depositor.

<PAGE>   49
 

     The Depositor and the Administrative Trustees on behalf of the Trust shall

Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314(c) of the Trust Indenture Act.
Any certificate or opinion required to be given by an officer pursuant to

          (a) The number of Trustees shall be five, provided that the Holder of
all of the Common Securities by written instrument may increase or decrease the
number of Administrative Trustees.  The Property Trustee and the Delaware

          (b) If a Trustee ceases to hold office for any reason and the number
of Administrative Trustees is not reduced pursuant to Section 817(a), or if the
number of Trustees is increased pursuant to Section 817(a), a vacancy shall
occur.  The vacancy shall be filled with a Trustee appointed in accordance with
Section 810.

          (c) The death, resignation, retirement, removal, bankruptcy,

Trustees in office, regardless of their number (and notwithstanding any other
provision of this Agreement), shall have all the powers granted to the

                                   ARTICLE IX
                      TERMINATION, LIQUIDATION AND MERGER

     SECTION 901.  TERMINATION UPON EXPIRATION DATE.

     Unless earlier dissolved, the Trust shall automatically dissolve on,
[2051] (the "Expiration Date") subject to distribution of the Trust Property in
accordance with Section 904.

     SECTION 902.  EARLY TERMINATION.

     The first to occur of any of the following events is an "Early Termination
Event":

          (a) the occurrence of a Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor;

          (b) delivery of written direction to the Property Trustee by the
Depositor at any time (which direction is wholly optional and within the
discretion of the Depositor) to dissolve the Trust and distribute the
Debentures to Securityholders in exchange for the Preferred Securities in
accordance with Section 904;

          (c) the redemption of all of the Preferred Securities in connection
with the redemption of all of the Debentures; and

          (d) an order for dissolution of the Trust shall have been entered by a
court of competent jurisdiction.

     SECTION 903. TERMINATION

     The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 904, or upon the
redemption of all of the Trust Securities pursuant to Section 402, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; and (c) the
discharge of all administrative duties of the Administrative 




                                       45
<PAGE>   51
 
Trustees, including the performance of any tax reporting obligations with 
respect to the Trust or the Securityholders, and (d) the filing of a
Certificate of cancelation by the Administrative Trustee under the Business
Trust Act.

     SECTION 904.  LIQUIDATION.

          (a) If an Early Termination Event specified in clause (a), (b), or (d)
of Section 902 occurs or upon the Expiration Date, the Trust shall be liquidated
by the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, to each Securityholder a Like Amount of Debentures,
subject to Section 904(d).  Notice of liquidation shall be given by the Property
Trustee by first-class mail, postage prepaid, mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Securities at
such Holder's address appearing in the Securities Register.  All notices of
liquidation shall:

               (i) state the Liquidation Date;

               (ii) state that from and after the Liquidation Date, the Trust
Securities will no longer be deemed to be Outstanding and any Trust Securities
Certificates not surrendered for exchange will be deemed to represent a Like
Amount of Debentures; and

               (iii) provide such information with respect to the mechanics by
which Holders may exchange Trust Securities certificates for Debentures, or if
Section 904(d) applies receive a Liquidation Distribution, as the Administrative
Trustees or the Property Trustee shall deem appropriate.

          (b) Except where Section 902(c) or 904(d) applies, in order to effect
the liquidation of the Trust and distribution of the Debentures to
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

          (c) Except where Section 902(c) or 904(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
outstanding, (ii) certificates (or, at the election of the Depositor a Global
Debenture, subject to the provisions of the Indenture) representing a Like
Amount of Debentures will be issued to holders of Trust Securities Certificates
upon surrender of such certificates to the Administrative Trustees or their
agent for exchange, (iii) the Depositor shall use its reasonable efforts to have
the Debentures listed on The Nasdaq National Market or on such other securities
exchange or other organization as the Preferred Securities are then listed or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest 




                                       46
<PAGE>   52


or principal will be made to holders of Trust Securities Certificates
with respect to such Debentures) and (v) all rights of Securityholders holding
Trust Securities will cease, except the right of such Securityholders to
receive Debentures upon surrender of Trust Securities Certificates.

     (d) In the event that, notwithstanding the other provisions of this
Section 904, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee in such manner as
the Property Trustee determines.  In such event, on the date of the
dissolution, winding-up or other termination of the Trust, Securityholders will
be entitled to receive out of the assets of the Trust available for
distribution to Securityholders, after satisfaction of liabilities to creditors
of the Trust as provided by applicable law, an amount equal to the Liquidation
Amount per Trust Security plus accumulated and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution").  If,
upon any such dissolution, winding-up or termination, the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then, subject
to the next succeeding sentence, the amounts payable by the Trust on the Trust
Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The holder of the Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution, winding-up or termination pro rata
(determined as aforesaid) with Holders of Preferred securities, except that, if
a Debenture Event of Default has occurred and is continuing, the Preferred
Securities shall have a priority over the Common Securities.

     SECTION 905.  MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF
                   THE TRUST.

     The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except pursuant
to this Section 905.  At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the holders of the Preferred
Securities, the Property Trustee or the Delaware Trustee, the Trust may merge
with or into, consolidate, amalgamate, be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any state; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities) so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii) the
Depositor expressly appoints a trustee of such successor entity possessing
substantially the same powers and duties as the Property Trustee as the holder
of the Debentures, (iii) the Successor Securities are listed or traded, or any
Successor Securities will be listed or traded upon notification of issuance, on
any national securities exchange or other organization on which the Preferred
Securities are then listed, if any, (iv) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not cause the
Preferred Securities (including any Successor Securities) to be downgraded by
any nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation, 


                                      47



<PAGE>   53


replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the holders of the Preferred
Securities (including any Successor Securities) in any material respect, (vi)
prior to suh merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Depositor has received an
opinion of Counsel to the effect that (a) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the holders of the Preferred
Securities (including any Successor Securities) in any material respect, and
(b) following such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, neither the Trust nor such successor entity will
be required to register as an investment Company under the 1940 Act and (vii)
the Depositor owns all of the Common Securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Guarantee.  Notwithstanding
the foregoing, the Trust shall not, except with the consent of holders of 100%
in Liquidation Amount of the Preferred Securities, consolidate, amalgamate,
merge with or into, or be replaced by or convey, transfer or lease its
properties and assets substantially as an entirety to any other Person or
permit any other Person to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger or replacement would
cause the Trust or the successor entity to be classified as other than a
grantor trust for United States federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

SECTION 1001.  LIMITATION OF RIGHTS OF SECURITYHOLDERS.

     The death or incapacity of any Person having an interest, beneficial or
otherwise, in Trust Securities shall not operate to terminate this Trust
Agreement, nor entitle the legal representatives or heirs of such Person or any
Securityholder for such Person, to claim an accounting, take any action or
bring any proceeding in any court for a partition or winding-up of the
arrangements contemplated hereby, nor otherwise affect the rights, obligations
and liabilities of the parties hereto or any of them.

SECTION 1002.  AMENDMENT.

     (a) This Trust Agreement may be amended from time to time by the Trustees
and the Depositor, without the consent of any Securityholders, (i) as provided
in Section 811 with respect to acceptance of appointment by a successor
Trustee, (ii) to cure any ambiguity, correct or supplement any provision herein
or therein which may be inconsistent with any other provision herein or
therein, or to make any other provisions with respect to matters or questions
arising under this Trust Agreement, that shall not be inconsistent with the
other provisions of this Trust Agreement, or (iii) to modify, eliminate or add
to any provisions of this Trust Agreement to such extent as shall be necessary
to ensure that the Trust will be classified for United States federal income
tax purposes as a grantor trust at all times that any Trust Securities are
outstanding or to ensure that the Trust will not be required to register as an
"Investment Company" under the 1940 Act; provided, however, that in the case of
clause (ii), such action shall not adversely affect in any material respect the
interests of 

                                      48


<PAGE>   54



any Securityholder, and any amendments of this Trust Agreement
shall become effective when notice thereof is given to the Securityholders.

    (b) Except as provided in Section 601(c) or Section 1002(c) hereof, any     
provision of this Trust Agreement may be amended by the Trustees and the
Depositor (i) with the consent of Trust Securityholders representing not
less than a majority (based upon Liquidation Amounts) of the Trust
Securities then Outstanding and (ii) upon receipt by the Trustees of an
opinion of Counsel to the effect that such amendment or the exercise of any
power granted to the Trustees in accordance with such amendment will not
affect the Trust's status as a grantor trust for United States federal
income tax purposes or the Trust's exemption from status of an "investment
company" under the 1940 Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder (such consent
being obtained in accordance with Section 603 or 606 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount
of any Distribution required to be made in respect of the Trust Securities as
of a specified date or (ii) restrict the right of a Securityholder to institute
suit for the enforcement of any such payment on or after such date;
notwithstanding any other provision herein, without the unanimous consent of
the Securityholders (such consent being obtained in accordance with Section 603
or 606 hereof), this paragraph (c) of this Section 1002 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an "investment company" under the 1940 Act or to fail or cease to be
classified as a grantor trust for United States federal income tax purposes.

     (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor, this Trust Agreement may not be amended
in a manner which imposes any additional obligation on the Depositor.

     (f) In the event that any amendment to this Trust Agreement is made, the
Administrative Trustees shall promptly provide to the Depositor a copy of such
amendment.

     (g) Neither the Property Trustee nor the Delaware Trustee shall be
required to enter into any amendment to this Trust Agreement which affects its
own rights, duties or immunities under this Trust Agreement.  The Property
Trustee shall be entitled to receive an Opinion of Counsel and an Officers'
Certificate stating that any amendment to this Trust Agreement is in compliance
with this Trust Agreement.

                                      49
<PAGE>   55

REGARD TO CONFLICT OF LAWS PRINCIPLES).

otherwise provided in Sections 401(a) and 402(d)), with the same force and
effect as though made on the date fixed for such payment, and no distribution
shall accumulate thereon for the period after such date.

<PAGE>   56


also be given to such owners as have, within two years
preceding the giving of such notice, filed their names and addresses with the
Property Trustee for that purpose.  Such notice, demand or other communication
to or upon a Securityholder shall be deemed to have been sufficiently given or
made, for all purposes, upon hand delivery, mailing or transmission.

the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 1009, the
Property Trustee agrees, for the benefit of Securityholders, that at the
expense of the Depositor (which expense shall be paid prior to the filing), it
shall file an answer with the bankruptcy court or otherwise properly contest
the filing of such petition by the Depositor against the Trust or the
commencement of such action and raise the defense that the Depositor has agreed
in writing not to take such action and should be stopped and precluded
therefrom.  The provisions of this Section 1009 shall survive the termination
of this Trust Agreement.

     SECTION 1010.  TRUST INDENTURE ACT; CONFLICT WITH TRUST INDENTURE ACT.

Indenture Act that are required to be part of this Trust Agreement and shall,

                                      51

Indenture Act, such required provision shall control.  If any provision of this
Trust Agreement modifies or excludes any provision of the Trust Indenture Act

apply to this Trust Agreement as so modified or to be excluded, as the case may
be.
        
             (d) The application of the Trust Indenture Act to this Trust 
Agreement shall not affect the nature of the Securities as equity securities
representing undivided beneficial interests in the assets of the Trust.

INDENTURE.

     THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN BY

Re:  IBC Capital Finance
     Cumulative Trust Preferred Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DEPOSITORY TRUST
COMPANY") of IBC Capital Finance Preferred Securities (the "Preferred
Securities"), of IBC Capital Finance, a Delaware business trust (the
"Issuer"),created pursuant to a Trust Agreement between Independent Bank
Corporation, a Michigan corporation ("IBC"), State Street Bank and Trust
Company, as Property Trustee, Wilmington Trust Company, as Delaware Trustee and
the Administrative Trustees named therein.  The payment of distributions on the
Preferred Securities and payments due upon liquidation of Issuer or redemption
of the Preferred Securities, to the extent the Issuer has funds available for
the payment thereof, are guaranteed by IBC to the extent set forth in a
Guarantee Agreement dated November _, 1996 by IBC with respect to the Preferred
Securities.  IBC and the Issuer propose to sell the Preferred Securities to
certain Underwriters (the "Underwriters") pursuant to an Underwriting Agreement
dated November _, 1996 by and among the Underwriters, the Issuer and IBC, and
the Underwriters wish to take delivery of the Preferred Securities through
DEPOSITORY TRUST COMPANY. State Street Bank and Trust Company is acting as
transfer agent and registrar with respect to the Preferred Securities (the
"Transfer Agent and Registrar").

     To induce DEPOSITORY TRUST COMPANY to accept the Preferred Securities as
eligible for deposit at DEPOSITORY 

                                     B-1
<PAGE>   62


TRUST COMPANY, and to act in accordance with DEPOSITORY TRUST COMPANY's rules
with respect to the Preferred Securities, the Issuer, the Transfer Agent and
Registrar and DEPOSITORY TRUST COMPANY agree among each other as follows:

     1.   Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about November _, 1996, there
shall be deposited with DEPOSITORY TRUST COMPANY one or more global
certificates (individually and collectively, the "Global Certificate")
registered in the name of DEPOSITORY TRUST COMPANY's Preferred Securities
nominee, Cede & Co., representing an aggregate of Preferred Securities and
bearing the following legend:


          Unless this certificate is presented by an authorized 
          representative of The Depository Trust Company, a New York
          corporation ("DEPOSITORY TRUST COMPANY"), to  Issuer or its 
          agent for registration of transfer,  exchange, or payment, 
          and any certificate issued is registered in the name of 
          Cede & Co. or in such other name as is requested by an 
          authorized representative of DEPOSITORY TRUST COMPANY (and 
          any payment is made to Cede & Co. or to such other entity 
          as is requested by an authorized representative of DEPOSITORY
          TRUST COMPANY), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR 
          VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as 
          the registered owner hereof, Cede & Co., has an interest herein.

     2.   The Amended and Restated Trust Agreement of the Issuer provides for 
the voting by holders of the Preferred Securities under certain limited
circumstances.  The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DEPOSITORY TRUST COMPANY notice of such
record date not less than 15 calendar days in advance of such record date.

     3.   In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation
of all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DEPOSITORY TRUST COMPANY a notice of
such event at least 5 business days prior to the effective date of such event.

     4.   In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DEPOSITORY TRUST COMPANY a notice
specifying: (a) the amount of and conditions, if any, applicable to the payment
of any such distribution or any such offering or issuance of rights; (b) any
applicable expiration or deadline date, or any date by which any action on the
part of the holders of Preferred Securities is required; and (c) the date any
required notice is to be mailed by or on behalf of the Issuer to holders of
Preferred Securities or published by or on behalf of the Issuer (whether by
mail or publication, the "Publication Date").  Such notice shall be sent to
DEPOSITORY TRUST COMPANY by a secure means (e.g., legible telecopy, registered
or certified mail, overnight delivery) in a timely manner designed to assure
that such notice is in DEPOSITORY TRUST COMPANY's possession no later than t '
he close of business on the business day before the Publication Date.  The

and obligations as are specifically set forth in this Preferred Securities
Guarantee, and no implied covenants or obligations shall be read into this
Preferred Securities Guarantee against the Preferred Guarantee Trustee; and

             (B) in the absence of bad faith on the part of the Preferred 
Guarantee Trustee, the Preferred Guarantee Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed

requirements of this Preferred Securities Guarantee;
        
         (ii) the Preferred Guarantee Trustee shall not be liable for any

Trustee, or exercising any trust or power conferred upon the Preferred
Guarantee Trustee under this Preferred Securities Guarantee; and
        
         (iv) no provision of this Preferred Securities Guarantee shall 
require the Preferred Guarantee Trustee to expend or risk its own funds or
otherwise incur personal financial liability in the performance of any of its
duties or in the exercise of any of its  rights or powers, if the Preferred
Guarantee Trustee shall have reasonable grounds for believing that the
repayment of such funds or liability is not reasonably assured to it under the
terms of this Preferred Securities Guarantee or indemnity, reasonably
satisfactory to the Preferred Guarantee Trustee, against such risk or liability
is not reasonably assured to it.

investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,

SECTION 5.1 Guarantee

     The Guarantor irrevocably and unconditionally agrees to pay in full to the
Holders the Guarantee Payments (without duplication of amounts theretofore paid

to pay such amounts to the Holders.

SECTION 5.2 Waiver of Notice and Demand

     The Guarantor hereby waives notice of acceptance of this Preferred
Securities Guarantee and of any liability to which it applies or may apply,

redemption and all other notices and demands.

performance or observance by IBC Capital of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be
performed or observed by IBC Capital;

portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or
in connection with, the Preferred Securities (other than an extension of time
for payment of Distributions, Redemption Price, Liquidation Distribution or
other sum payable that results from the extension of any interest payment
period on the Debentures or any extension of the maturity date of the
Debentures permitted by the Indenture);

     (c) any failure, omission, delay or lack of diligence on the part of the

Capital;

     (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

     (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

     (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.
        
     There shall be no obligation of the Holders to give notice to, or obtain
consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4 Rights of Holders

     (a) The Holders of a Majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting of
any proceeding for any remedy available to the Preferred Guarantee Trustee in
respect of this Preferred Securities Guarantee or exercising any trust or power
conferred upon the Preferred Guarantee Trustee under this Preferred Securities
Guarantee.

     (b) Any Holder of Preferred Securities may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Preferred
Securities Guarantee, without first instituting a legal proceeding against IBC
Capital, the Preferred Guarantee Trustee or any other Person.

SECTION 5.5 Guarantee of Payment

     This Preferred Securities Guarantee creates a guarantee of payment and not
of collection.

SECTION 5.6 Subrogation

     The Guarantor shall be subrogated to all (if any) rights of the Holders of

Holders by the Guarantor under this Preferred Securities Guarantee; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Preferred Securities
Guarantee, if, at the time of any such payment, 



                                     12
<PAGE>   17

any amounts are due and unpaid under this Preferred Securities Guarantee.  If

sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.
        
SECTION 5.7 Independent Obligations

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of IBC Capital with respect to the Preferred Securities, and

Guarantor and with any guarantee now or hereafter entered into by the Guarantor
in respect of any preferred or preference stock of any Affiliate of the
Guarantor, and (iii) senior to the Guarantor's common stock.

Preferred Securities Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder of Preferred
Securities must restore payment of any sums paid under the Preferred Securities
or under this Preferred Securities Guarantee.

believed to be within the scope of the authority conferred on such Indemnified
Person by this Preferred Securities Guarantee or by law, except that an

incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses (including reasonable legal fees

liability in connection with the exercise or performance of any of its powers
or duties hereunder.  The obligation to indemnify as set forth in this Section

Board of Directors
Independent Bank Corporation
230 West Main Street
Ionia, MI 48846

Gentlemen:

     We have acted as counsel to Independent Bank Corporation, a Michigan
corporation (the "Company") in connection with the Registration Statement on
Form S-2 (the "Registration Statement"), as amended, filed with the Securities
and Exchange Commission (Registration No. 333-14507) for the purpose of
registering under the Securities Act of 1933, as amended, 690,000      %
Cumulative Trust Preferred Securities ("Preferred Securities") of IBC Capital
Finance ("IBC Capital"), a Delaware statutory business trust, wholly owned by
the Company.  The Preferred Securities represent beneficial interests in IBC
Capital.  IBC Capital will exist solely to issue the Preferred Securities and
to invest the proceeds in        % Debentures ("Subordinated Debentures") to be
issued by the Company.

     We are familiar with the corporate action taken by the Board of Directors
of the Company (1) authorizing the establishment of a Delaware statutory
business trust to be known as IBC Capital Finance, (2) creating and authorizing
for sale to IBC Capital the      % Junior Subordinated Debentures, (3)
executing a Debenture Indenture which shall operate as the formal agreement
governing the relationship between the Company as issuer of the Debentures and
IBC Capital as holder of such Debentures, (4) creating and executing a
Guarantee Agreement which shall require the Company to guarantee certain
obligations of IBC Capital with respect to its Preferred Securities, (5)
authorizing the execution of an Expense Agreement as to the expenses and
liabilities between the Company and IBC Capital which shall guarantee to
parties to whom the IBC Capital becomes indebted or liable full payment of such
obligations, other than the obligation of IBC Capital to pay the holders of any
Preferred Securities the amounts due under such securities, and we have
examined such documents and questions of law as we consider necessary or
appropriate for the purpose of furnishing this opinion.

     It is our opinion that the 690,000 Debentures being issued by the Company
to IBC Capital as described in the Registration Statement in accordance with
the terms stated in the Registration Statement, at the time it becomes
effective, and as described in the Debenture Indenture, will be legally and
validly authorized and issued.

giving this consent, we do not thereby admit that we are within the category of

IBC Capital Finance
c/o Independent Bank Corporation

Ionia, Michigan 48846


     Re:   IBC Capital Finance

Ladies and Gentlemen:

     We have acted as special Delaware counsel for IBC Capital Finance, a
Delaware business trust (the "Trust"), in connection with the matters set forth
herein.  At your request, this opinion is being furnished to you.

     For purposes of giving the opinions hereinafter set forth, our examination
of documents has been limited to the examination of originals or copies of the
following:

     (a) The Certificate of Trust of the Trust, dated November __, 1996 (the
"Certificate"), as filed in the office of the Secretary of State of the State
of Delaware (the "Secretary of State") on November __, 1996;

     (b) The Trust Agreement of the Trust, dated as of November __, 1996, among
Independent Bank Corporation, a Michigan corporation ("IBC"), and the trustees
of the Trust named therein;

     (c) The Registration Statement (the "Registration Statement") on Form S-3,
including a prospectus (the "Prospectus") relating to the __% Preferred
Securities of the Trust representing preferred undivided beneficial interests
in the Trust (each, a "Preferred Security" and 



<PAGE>   2

Independent Bank Corporation
November __, 1996
Page 2


collectively, the "Preferred Securities"), as filed by IBC, the Trust and
others as set forth therein with the Securities and Exchange Commission on
November __, 1996;

     (d) A form of Amended and Restated Trust Agreement of the Trust, to be
entered into among IBC, the trustees of the Trust named therein, and the
holders, from time to time, of undivided beneficial interests in the Trust (the
"Trust Agreement"), attached as an exhibit to the Registration Statement; and 

     (e) A Certificate of Good Standing for the Trust, dated the date hereof,
obtained from the Secretary of State.

     Initially capitalized terms used herein and not otherwise defined are used
as defined in the Trust Agreement.

     For purposes of this opinion, we have not reviewed any documents other
than the documents listed above, and we have assumed that there exists no
provision in any document that we have not reviewed that bears upon or is
inconsistent with the opinions stated herein.  We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to
be true, complete and accurate in all material respects.

     With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

     For purposes of this opinion, we have assumed (i) that the Trust Agreement
constitutes the entire agreement among the parties thereto with respect to the
subject matter thereof, including with respect to the creation, operation and
termination of the Trust, and that the Trust Agreement and the Certificate are
in full force and effect and have not been amended, (ii) except to the extent
provided in paragraph 1 below, the due creation or due organization or due
formation, as the case may be, and valid existence in good standing of each
party to the documents examined by us under the laws of the jurisdiction
governing its creation, organization or formation, (iii) the legal capacity of
natural persons who are parties to the documents examined by us, (iv) that each
of the parties to the documents examined by us has the power and authority to
execute and deliver, and to perform its obligations under, such documents, (v)
the due authorization, execution and delivery by all parties thereto of all
documents examined by us, (vi) the receipt by each Person to whom a Preferred
Security is to be issued by the Trust (collectively, the "Preferred Security
Holders") of a Preferred Security Certificate for such Preferred Security and
the payment for the Preferred Security acquired by it, in accordance with the
Trust Agreement and the Prospectus, and (vii) that the Preferred Securities are
issued and sold to the Preferred Security Holders in accordance with the Trust
Agreement and the Prospectus.  We have not

Page 3



participated in the preparation of the Registration Statement and assume no
responsibility for its contents. 

     This opinion is limited to the laws of the State of Delaware (excluding
the securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal
laws and rules and regulations relating thereto.  Our opinions are rendered
only with respect to Delaware laws and rules, regulations and orders thereunder
which are currently in effect.

     Based upon the foregoing, and upon our examination of such questions of
law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

     1. The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, 12 Del. C.
Section  3801, et seq.

     2. The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

     3. The Preferred Security Holders, as beneficial owners of the Trust, will
be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

     We consent to the filing of this opinion with the Securities and Exchange
Commission as an exhibit to the Registration Statement.  In addition, we hereby
consent to the use of our name under the heading "Legal Matters" in the
Prospectus.  In giving the foregoing consents, we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.  Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.

                                           Very truly yours,

EAM
