                             ABOUT THIS PROSPECTUS
 
     This Prospectus is part of a registration statement on Form S-3 that we and
Flagstar Trust have filed with the Securities and Exchange Commission (the
"SEC") relating to Flagstar Trust's Preferred Securities being offered by this
Prospectus. As permitted by SEC rules, this Prospectus does not contain all of
the information contained in the registration statement and accompanying
exhibits and schedules we file with the SEC. You may refer to the registration
statement, the exhibits and schedules for more information about us and Flagstar
Trust's Preferred Securities. The registration statement, exhibits and schedules
are also available at the SEC's public reference rooms or through its EDGAR
database on the internet.
 
                      WHERE YOU CAN FIND MORE INFORMATION
 
     We file annual, quarterly and current reports, proxy statements and other
information with the SEC. You may read and copy, upon payment of a fee set by
the SEC, any document that we file with the SEC at its public reference rooms in
Washington, D.C. (450 Fifth Street, N.W., 20549), New York, New York (Seven
World Trade Center, 13th Floor, Suite 1300, 10048) and Chicago, Illinois
(Citicorp Center, 500 West Madison Street, 14th Floor, Suite 1400, 60661). You
may also call the SEC at 1-800-432-0330 for more information on the public
reference rooms. Our filings are also available to the public on the internet,
through the SEC's EDGAR database. You may access the EDGAR database at the SEC's

     You may also obtain a copy of these filings from us at no cost upon your
written or oral request to us. Please direct your requests to our Corporate
Secretary, Mary Kay McGuire, at Flagstar Bancorp, Inc., 2600 Telegraph Road,
Bloomfield Hills, Michigan, 48302-0953, or by telephoning us at (248) 338-7700.
To obtain timely delivery, you must request the information no later than five
business days prior to the date you decide to invest in Flagstar Trust's
Preferred Securities.
 
     The SEC allows us to "incorporate by reference" into this Prospectus the
information we file with them. This means that we can disclose important
business, financial and other information in our SEC filings by referring you to
the documents containing this information. Any information referred to in this
way is considered part of this Prospectus, and any information filed with the
SEC by us after the date of this Prospectus will automatically be deemed to
update and supersede this information. We incorporate by reference the documents
listed below and any future filings made with the SEC under Sections 13(a),
13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act")
until we file a post-effective amendment to the Form S-3 indicating the
termination of this offering:
 
     - Annual Report on Form 10-K for the year ended December 31, 1998.
 
     There are not separate financial statements of Flagstar Trust in this
Prospectus. We do not believe such financial statements would be helpful
because:
 
     - Flagstar Trust is a subsidiary of Flagstar Bancorp, Inc., which files
       consolidated financial information under the Exchange Act.
 
     - Flagstar Trust does not have any independent operations other than
       issuing the preferred and common securities and purchasing the Junior
       Subordinated Debentures of Flagstar Bancorp, Inc.
 
     - Flagstar Trust's only material assets will be the Junior Subordinated
       Debentures of Flagstar Bancorp, Inc. when issued.
 
     - The combined obligations of Flagstar Bancorp, Inc. under the Junior
       Subordinated Debentures, the Guarantee, the Trust Agreement and the
       Indenture (each as we define later) have the effect of providing a full
       and unconditional guarantee of Flagstar Trust's
 
                                        3

                       SPECIAL NOTE OF CAUTION REGARDING
                           FORWARD-LOOKING STATEMENTS
 
     Certain statements contained in (i) this Prospectus, (ii) any applicable
amendment to this Prospectus and (iii) the documents incorporated by reference
into this Prospectus, may constitute "forward-looking statements" within the
meaning of the federal securities laws. Forward-looking statements are based on
our management's beliefs, assumptions and expectations of our future economic
performance, taking into account the information currently available to them.
These statements are not statements of historical fact. Forward-looking
statements involve risks and uncertainties that may cause our actual results,
performance or financial condition to be materially different from the
expectations of future results, performance or financial condition we express or
imply in any forward-looking statements. Some of the important factors that
could cause our actual results, performance or financial condition to differ
materially from our expectations are:
 
     - The effect that changes in interest rates have on our earnings and
       assets.
 
     - Our cost of funds.
 
     - Our ability to resell mortgages.
 
     - Our level of loan defaults and delinquencies.
 
     - Concentrations of our loans in one geographic area or with a few mortgage
       companies.
 
     - The seasonal variations in the mortgage banking business.
 
     - Our ability to manage our retail banking expansion.
 
     - Our ability to retain key personnel.
 
     - The degree and nature of our competition.
 
     - Changes in government regulation of our business.
 
     - The threat of litigation in the mortgage banking business.
 
     - Environmental liability associated with foreclosures.
 
     - The effect of the Year 2000 problem on us and on those entities with
       which we deal.
 
     When used in our documents or oral presentations, the words "believe,"
"may," "will," "should," "anticipate," "estimate," "expect," "objective,"
"projection," "forecast," "goal," or similar words or the negatives of these
words are intended to identify forward-looking statements. We qualify any such
forward-looking statements entirely by these cautionary factors.

       average assets of 1.29% and return on average equity of 20.69% for the
       same period in 1997.
 
     Our primary lines of business are mortgage banking and retail banking.
 
     - Our mortgage banking operations originate residential mortgages through
       31 retail loan origination offices located in Michigan (27), Florida (3)
       and Ohio (1), as well as a nationwide network of independent mortgage
       brokers.
 
     - We currently operate a network of 30 retail bank branches located in
       Michigan, including two opened in 1999.
 
     For the year ended December 31, 1998, we produced $18.8 billion in mortgage
loans as compared to $7.9 billion in 1997. In addition, our loan servicing
portfolio totaled $11.5 billion at December 31, 1998 as compared to $6.4 billion
at December 31, 1997. Substantially all of our servicing portfolio (net of loans
subserviced for others) is comprised of conventional loans.
 
     OUR BUSINESS STRATEGY
 
     Our strategy consists of the following key elements:
 
     - continue to expand our bank branch network into demographically desirable
       communities in Michigan in order to gain access to additional deposits;
 
     - as market conditions permit, retain a portion of our mortgage loan
       production volume or mortgage servicing rights or both (thereby
       benefiting from economies of scale);
 
                                        5
<PAGE>   7
 
     - continue to utilize advanced technology and automated processes
       throughout our business to improve customer service, reduce costs of loan
       production and servicing and increase efficiencies; and
 
     - cross-sell retail banking services to our large Michigan base of existing
       mortgage customers.
 
     FLAGSTAR TRUST
 
     Flagstar Trust is a Delaware business trust. Flagstar Trust will exist
solely to:
 
     - issue and sell its Common Securities to us;
 
     - issue and sell its Preferred Securities to the public;
 
     - use the proceeds from the sale of its Common Securities and Preferred
       Securities to purchase the Junior Subordinated Debentures from us;
 
     - distribute the cash payments it receives on the Junior Subordinated
       Debentures it owns to the holders of the Preferred and Common Securities;
       and
 
     - engage in other activities that are necessary or incidental to these
       purposes.
 
     Flagstar Bancorp's and Flagstar Trust's principal executive offices are
located at 2600 Telegraph Road, Bloomfield Hills, Michigan, 48302-0968. The main
telephone number for both Flagstar Bancorp and Flagstar Trust is (248) 338-7700.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, you should
carefully consider the following factors before investing in the Preferred
Securities.
 
PREFERRED SECURITIES RISK FACTORS
 
     THE HOLDERS OF OUR SENIOR AND SUBORDINATED DEBT WILL GET PAID BEFORE YOU
WILL GET PAID UNDER THE GUARANTEE.
 
     Our obligations under the Junior Subordinated Debentures are unsecured and
rank junior in right of payment to all of our Senior and Subordinated Debt and
equal to any junior debt securities we may later have.
 
     The Preferred Securities, the Junior Subordinated Debentures and the
Guarantee do not limit our ability to incur additional indebtedness, including
indebtedness that ranks senior to the Junior Subordinated Debentures and the
Guarantee. See "Description of Guarantee -- Status of Guarantee" and
"Description of the Junior Subordinated Debentures -- Subordination."
 
     IF WE DO NOT MAKE PAYMENTS UNDER THE JUNIOR SUBORDINATED DEBENTURES,
FLAGSTAR TRUST WILL BE UNABLE TO PAY DISTRIBUTIONS AND LIQUIDATION AMOUNTS AND
THE PREFERRED SECURITIES GUARANTEE WILL NOT APPLY.
 
     The ability of Flagstar Trust to pay Distributions and, upon redemption,
the Liquidation Amount of $25 per Preferred Security is solely dependent upon
our ability to make the related payments on the Junior Subordinated Debentures
when due. If we default on our obligation to pay principal of or interest on the
Junior Subordinated Debentures, Flagstar Trust will not have sufficient funds to
pay Distributions or the Liquidation Amount.
 
     In that case, you will not be able to rely upon the Preferred Securities
Guarantee for payment of these amounts because the Preferred Securities
Guarantee only applies if we make a payment of principal or interest on the
Junior Subordinated Debentures. For more information on our obligations under
the Preferred Securities Guarantee and the Junior Subordinated Debentures, see
"Description of Guarantee -- Status of Guarantee" and "Description of the Junior
Subordinated Debentures -- Subordination."
 
     OUR INTEREST PAYMENTS ON THE JUNIOR SUBORDINATED DEBENTURES ARE DEPENDENT
ON OUR RECEIPT OF DIVIDENDS FROM THE BANK.
 
     A substantial majority of our assets consists of our investment in the
Bank. Thus, our ability to pay interest and principal on the Junior Subordinated
Debentures to Flagstar Trust depends primarily upon our receipt of cash
dividends from the Bank. Dividend payments from the Bank to us are subject to,
among other things:
 
     - regulatory limitations, generally based on current and retained earnings
       and capital maintenance requirements, imposed by various bank regulatory
       agencies;
 
     - profitability, financial condition and capital expenditures and other
       cash flow requirements of the Bank; and
 
     - prior claims of creditors of the Bank.
 
     This means that the Junior Subordinated Debentures will be effectively
subordinated to all obligations of our subsidiaries. For example, our Bank
currently has a subsidiary that acts as a real estate investment trust ("REIT")
and sold preferred shares to the public. If the Bank is required to terminate
the REIT, the REIT's preferred shares will be exchanged for the Bank's preferred
shares. If this happens, the Bank's funds would be used first to satisfy its
obligations on its own preferred shares before paying any dividends to the
Company.
 
                                        7
<PAGE>   9
 
     If the Bank is unable to pay sufficient dividends to us, then we will
likely be unable to make payments on the Junior Subordinated Debentures, thereby
leaving insufficient funds for Flagstar Trust to make payments to you on the
Preferred Securities.
 
     DISTRIBUTIONS ON THE PREFERRED SECURITIES MAY BE DEFERRED; YOU MAY HAVE TO
INCLUDE INTEREST IN YOUR TAXABLE INCOME BEFORE YOU RECEIVE CASH.
 
     It is possible that you will not receive cash distributions on the
Preferred Securities for up to 20 consecutive quarters (in each case, an
"Extension Period"). We have the right, at one or more times, to defer interest
payments on the Junior Subordinated Debentures for up to 20 consecutive
quarters, but not beyond the maturity date of the Junior Subordinated Debentures
and must make payments of all deferred interest upon the earlier of the end of
the Extension Period or the maturity date. This right exists only if no Event of
Default under the Junior Subordinated Debentures has occurred and is continuing.
If we exercise this right, Flagstar Trust could defer Distributions on the
Preferred Securities during any Extension Period. However, you would still
accumulate Distributions at the annual rate of      % of the Liquidation Amount
of $25 per Preferred Security, plus you will earn interest at the annual rate of
     %, compounded quarterly, on any unpaid Distributions. When we pay all the
accumulated amounts due to you during an Extension Period, the Extension Period
will terminate. However, we have the right to begin another Extension Period
under the same terms outlined above. There is no limit on the number of times we
can elect to begin an Extension Period. During an Extension Period, the
Preferred Securities may trade at a price that does not fully reflect the value
of accrued but unpaid Distributions. See "Description of the Preferred
Securities."
 
     You will also not receive the cash distributions related to any accrued and
unpaid interest from Flagstar Trust if you sell the Preferred Securities before
the end of an Extension Period. However, you will be required to include accrued
interest income as original issue discount for United States federal income tax
purposes in respect of your pro rata share of the Junior Subordinated Debentures
held by Flagstar Trust. While we will take the position that original issue
discount will not arise before the first Extension Period, it is possible that
all interest on the Junior Subordinated Debentures would be required to be
accounted for as original issue discount. In these circumstances, the receipt of
interest would not separately be reported as taxable income. See "United States
Federal Income Tax Consequences" for more information regarding the tax
consequences of the Preferred Securities.
 
     We have no current intention of exercising our right to defer interest
payments on the Junior Subordinated Debentures. However, if we exercise our
right in the future, the market price of the Preferred Securities is likely to
be adversely affected.
 
     IF WE REDEEM THE JUNIOR SUBORDINATED DEBENTURES IT WILL CAUSE A REDEMPTION
OF THE PREFERRED SECURITIES AND YOU MAY NOT BE ABLE TO REINVEST THE PROCEEDS AT
THE SAME OR HIGHER RATE OF RETURN.
 
     You are subject to prepayment risk of your Preferred Securities. If your
Preferred Securities are redeemed, you may not be able to reinvest the money you
receive in the redemption at a rate that is equal to or higher than the rate of
return you receive on the Preferred Securities. Although the Junior Subordinated
Debentures have a stated maturity date of             , 2029, they may be
redeemed by us prior to maturity which, in turn, would cause an early redemption
of the Preferred Securities, in the following circumstances:
 
     - In whole or in part, beginning on                2004 at our option.
 
     - In whole upon a change in the federal tax laws or a change in the
       interpretation of the tax laws by the courts or the Internal Revenue
       Service, which would result in a risk that (1) Flagstar Trust may be
       subject to federal income tax, (2) the interest we pay on the Junior
       Subordinated Debentures will not be deductible by us for federal income
       tax pur-
 
                                        8
<PAGE>   10
 
poses, or (3) Flagstar Trust is or will be subject to more than a minimal amount
of other taxes or governmental charges.
 
     - In whole upon a change in the laws or regulations to the effect that
       Flagstar Trust is or will be considered to be an investment company that
       is required to be registered under the Investment Company Act of 1940.
 
     - In whole upon a change in the laws or regulations if there is a risk that
       we will not be able to treat all or a substantial portion of the
       Preferred Securities as core capital for purposes of federal banking
       guidelines.
 
     Our exercise of these redemption rights is subject to our receipt of prior
approval of federal banking regulators, if required. For further information
concerning tax or regulatory events that may trigger redemption of the Junior
Subordinated Debentures and prepayment of the Preferred Securities, see
"Description of the Preferred Securities -- Redemption."
 
     DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO HOLDERS OF PREFERRED
SECURITIES MAY HAVE AN ADVERSE EFFECT ON THE MARKET PRICE OF YOUR INVESTMENT.
 
     Your investment in the Preferred Securities may decrease in value if the
Junior Subordinated Debentures are distributed to you in exchange for your
Preferred Securities. We cannot predict the liquidity or market prices for the
Junior Subordinated Debentures that may be distributed. Accordingly, the Junior
Subordinated Debentures that you receive upon a distribution, or the Preferred
Securities you hold pending such a distribution, may trade at a discount to the
price that you paid to purchase the Preferred Securities.
 
     Because you may receive Junior Subordinated Debentures, you must also make
an investment decision with regard to these securities. You should carefully
review all the information regarding the Junior Subordinated Debentures
contained in this Prospectus.
 
     Under "United States Federal Income Tax Consequences" we discuss applicable
United States federal income tax consequences of a distribution of the Junior
Subordinated Debentures.
 
     IN THE EVENT OF A DEFAULT UNDER THE PREFERRED SECURITIES, YOU MAY BE
REQUIRED TO RELY ON THE PROPERTY TRUSTEE OF FLAGSTAR TRUST TO ENFORCE YOUR
RIGHTS.
 
     You may not be able to directly enforce rights against us if an event of
default occurs with respect to the Junior Subordinated Debentures. For a listing
of events that are events of default, see "Description of the Preferred
Securities -- Events of Default, Notice" and "Description of the Junior
Subordinated Debentures -- Debenture Events of Default."
 
     If an event of default under the Junior Subordinated Debentures occurs and
is continuing, this event will also be an event of default under the Preferred
Securities. In that case, you generally would first have to rely on the Property
Trustee's enforcement of its rights as holder of the Junior Subordinated
Debentures against us. If the Property Trustee fails to exercise its rights
under the Junior Subordinated Debentures, you will then be able to exercise any
other remedies available under the Junior Subordinated Debentures.
 
     However, if the default arises because we fail to pay interest or principal
(except during an Extension Period) on the Junior Subordinated Debentures, you
may proceed directly against us without first relying on the Property Trustee.
 
     LIMITED COVENANTS RELATING TO THE PREFERRED SECURITIES AND THE JUNIOR
SUBORDINATED DEBENTURES WILL NOT NECESSARILY PROTECT YOU.
 
     Our obligations as set forth in the governing documents (i.e., relating to
the Preferred Securities and the Junior Subordinated Debentures) are limited. As
a result, the governing documents will not necessarily protect you in the event
of an adverse change in our financial
 
                                        9
<PAGE>   11
 
condition or results of operations. The governing documents do not limit our
ability or any of our subsidiaries to incur additional debt. You should not
consider the terms of the governing documents to be a significant factor in
evaluating whether we will be able to comply with our obligations under the
Junior Subordinated Debentures or the Guarantee.
 
     WE WILL CONTROL FLAGSTAR TRUST BECAUSE YOU WILL HAVE LIMITED VOTING RIGHTS.
 
     As a holder of Preferred Securities, you have limited voting rights. These
rights relate only to the modification of the Preferred Securities and removal
of the Property and Indenture Trustees of Flagstar Trust upon a limited number
of events. You will not have any voting rights regarding Flagstar Bancorp's
business or any matters regarding the Administrative Trustees. See "Description
of the Preferred Securities -- Voting Rights; Amendment of the Trust Agreement"
for more information on your limited voting rights.
 
     TRADING CHARACTERISTICS OF THE PREFERRED SECURITIES MAY CREATE ADVERSE TAX
CONSEQUENCES FOR YOU.
 
     The Preferred Securities may trade at a price that does not reflect the
value of accrued but unpaid interest on the underlying Junior Subordinated
Debentures. If you dispose of your Preferred Securities between record dates for
payments on the Preferred Securities, you may have adverse tax consequences.
Under these circumstances, you will be required to include accrued but unpaid
interest on the Junior Subordinated Debentures allocable to the Preferred
Securities through the date of disposition in your income as ordinary income.
 
     If interest on the Junior Subordinated Debentures is included in income
under the original issue discount provisions, you would add this amount to your
adjusted tax basis in your share of the underlying Junior Subordinated
Debentures deemed disposed. If your selling price is less than your adjusted tax
basis, which will include all accrued but unpaid original issue discount
interest included in your income, you could recognize a capital loss which,
subject to exceptions, cannot be applied to offset ordinary income for federal
income tax purposes. See "United States Federal Income Tax
Consequences -- Potential Extension of Interest Payment Period and Original
Issue Discount" and "-- Sale of Preferred Securities" for more information on
possible adverse tax consequences to you.
 
     THERE HAS NOT BEEN A PRIOR PUBLIC MARKET FOR THE PREFERRED SECURITIES, AND
AN ACTIVE TRADING MARKET FOR THE PREFERRED SECURITIES MAY NOT DEVELOP.
 
     The Preferred Securities constitute a new issue of securities with no
established trading market. Although an application for listing of the Preferred
Securities on The Nasdaq Stock Market(R) has been filed, there can be no
assurance that our listing will be approved. Further, even if approved, a
listing does not guarantee that a trading market for the Preferred Securities
will develop. If a trading market does develop, there is no assurance of the
depth of that market or that holders of Preferred Securities will be able to
sell their Preferred Securities easily.
 
FLAGSTAR BANCORP RISK FACTORS
 
     ANY CHANGES IN INTEREST RATES MAY ADVERSELY AFFECT OUR EARNINGS AND
FINANCIAL CONDITION.
 
     Changes in interest rates affect our operating performance and financial
condition in diverse ways. Our profitability depends in substantial part on our
"net interest spread," which is the difference between the rates we receive on
loans and investments and the rates we pay for deposits and other sources of
funds. Our net interest spread will depend on many factors that are partly or
entirely outside our control, including competition, federal economic, monetary
and fiscal policies, and economic conditions generally. Historically, net
interest spreads for other financial institutions have widened and narrowed in
response to these and other factors, which are often collectively referred to as
"interest rate risk." We intend to try to minimize our exposure to interest rate
risk, but we will be unable to eliminate it.
 
                                       10
<PAGE>   12
 
     In our retail banking operations, we are subject to interest rate risk on
loans held in our portfolio arising from mismatches (i.e., the interest rate
sensitivity gap) between the dollar amount of repricing or maturing assets and
liabilities, which is measured in terms of the ratio of the interest rate
sensitivity gap to total assets. A higher level of assets repricing or maturing
than liabilities over a given time frame is considered asset-sensitive and is
reflected as a positive gap. In contrast, a higher level of liabilities
repricing or maturing than assets over a given time frame is considered
liability-sensitive and is reflected as a negative gap. An asset-sensitive
position (i.e., a positive gap) will generally enhance earnings in a rising
interest rate environment and will negatively impact earnings in a falling
interest rate environment. A liability-sensitive position (i.e., a negative gap)
will generally enhance earnings in a falling interest rate environment and
negatively impact earnings in a rising interest rate environment. Fluctuations
in interest rates are not predictable or controllable. Although we have
attempted to structure our asset and liability management strategies to mitigate
the impact on net interest income of changes in market interest rates, we can
not give any assurance that a sudden or significant change in prevailing
interest rates will not have a material adverse effect on our operating results.
 
     In our mortgage banking operations, we are exposed to interest rate risk
from the time the interest rate on a mortgage loan application is committed to
by us through the time we sell or commit to sell the mortgage loan. On a daily
basis, we analyze various economic and market factors and, based upon these
analyses, project the amount of mortgage loans we expect to sell for delivery at
a future date. The actual amount of loans we sell will be a percentage computed
as (i) the number of mortgage loans on which we have issued binding commitments
(and thereby locked in the interest rate) but have not yet closed ("pipeline
loans") divided by (ii) actual closings. If interest rates change in an
unanticipated fashion, the actual percentage of pipeline loans that close may
differ from the projected percentage. The resulting mismatch of commitments to
fund mortgage loans and commitments to sell mortgage loans may have an adverse
effect on the results of operations in any such period. For instance, a sudden
increase in interest rates can cause a higher percentage of pipeline loans to
close than projected. To the degree that this is not anticipated, we may not
have made commitments to sell these additional pipeline loans and may incur
significant losses upon their sale as the market rate of interest will be higher
than the mortgage interest rate we committed to on such additional pipeline
loans. Our profitability may be adversely affected to the extent our hedging
strategy is not successful.
 
     The market value of, and earnings from, our mortgage loan servicing
portfolio may be adversely affected by declines in interest rates. When mortgage
interest rates decline, mortgage loan prepayments usually increase as customers
refinance their loans. When this happens, the income stream from our current
mortgage loan servicing portfolio may decline. In that case, we may be required
to amortize the portfolio over a shorter period of time or reduce the carrying
value of our mortgage loan servicing portfolio. This would adversely affect our
operating results and financial condition.
 
     THE LOSS OF OR INCREASED COST OF OUR OPERATING FUNDS MAY REDUCE OUR
EARNINGS.
 
     The principal sources of funding for our operations have been bank deposits
and, to a lesser extent, borrowings from the Federal Home Loan Bank (the "FHLB")
and funds held in escrow for mortgage loan servicing purposes. Historically, our
cost of funds associated with deposits has generally been lower than our cost to
borrow from the FHLB. If we are unable to fund our asset growth through the
maintenance and growth of our deposit base, we may have to rely to a greater
extent on borrowings from the FHLB or other sources. If this causes our net cost
of funds to increase, our net interest margin would be adversely affected. At
December 31, 1998, we had a $1.3 billion line of credit with the FHLB, of which
$456.0 million had been drawn and was outstanding.
 
     We cannot assume that we will be successful in retaining our access to
funds at the level or cost necessary to continue originations of single-family
mortgage loans at their current volume
 
                                       11
<PAGE>   13
 
and level of profitability. We may have to curtail our origination of
single-family mortgage loans if we cannot maintain our low cost of funds. If we
have to reduce our single family mortgage loan originations, we may suffer a
material adverse effect on our operating results and financial condition.
 
     OUR PROFITABILITY WILL BE SIGNIFICANTLY REDUCED IF WE ARE NOT ABLE TO
RESELL MORTGAGES.
 
     Currently, we sell substantially all the mortgage loans we originate. Our
profitability depends in large part upon our ability to originate or purchase a
high volume of loans and to quickly sell them in the secondary market.
 
     Our ability to sell mortgage loans readily is dependent upon the
availability of an active secondary market for single-family mortgage loans,
which in turn depends in part upon the continuation of programs currently
offered by Fannie Mae, Freddie Mac, Ginnie Mae and other institutional and
non-institutional investors. These entities account for a substantial portion of
the secondary market in residential mortgage loans. Some of the largest
participants in the secondary market, including Fannie Mae, Freddie Mac and
Ginnie Mae, are government-sponsored enterprises whose activities are governed
by federal law. Any future changes in laws that limit the activity of such
government sponsored enterprises could, in turn, adversely affect our
operations.
 
     In addition, our ability to sell mortgage loans readily is dependent upon
our ability to remain eligible for the programs offered by Fannie Mae, Freddie
Mac, Ginnie Mae and other institutional and non-institutional investors. We
expect to remain eligible to participate in such programs but any significant
impairment of such eligibility could materially and adversely affect our
operations. Further, the criteria for loans to be accepted under such programs
may be changed from time to time by the sponsoring entity. The profitability of
participating in specific programs may vary depending on a number of factors,
including our administrative costs of originating and purchasing qualifying
loans.
 
     WE ARE AT RISK FOR LOSSES ON OUR LOANS THAT HAVE DEFAULTS OR DELINQUENCIES.
 
     We are generally at risk for any loan defaults from the time we fund a loan
until the time we sell the loan. This time period is generally 10 to 40 days.
Once we sell the mortgage loans, the risk of loss from loan defaults and
foreclosure generally passes to the purchaser or insurer of the loans. In
connection with the sale, we typically make certain representations and
warranties to the purchasers and insurers of such loans. Such representations
and warranties generally relate to the origination and servicing of loans in
substantial conformance with the laws of the state of origination and applicable
investor guidelines and program eligibility standards. We rely upon our
underwriting department to ascertain compliance with individual investor
standards prior to sale of the loans in the secondary market, and we rely upon
our quality control department to test sold loans on a sample basis for
compliance. The purchasers of such loans will typically conduct a more detailed
review of such loans following acquisition to determine whether such loans were
originated in compliance with the purchaser's underwriting guidelines and
program eligibility standards. We become liable for the unpaid principal and
interest on any defaulted mortgage loan if there has been a breach of our
representations and warranties. In such instances, we may be required to
repurchase the loan.
 
     We are also affected by loan delinquencies and defaults on mortgage loans
that we service. At December 31, 1998, approximately 1.83% of the loans we
serviced for others were 30 days or more delinquent (including foreclosures).
Under certain types of servicing contracts, the servicer must advance all or
part of the scheduled payments to the owner of the loan, even when loan payments
are delinquent. Also, to protect their liens on mortgaged properties, owners of
loans usually require the servicer to advance the cost of mortgage and hazard
insurance and tax payments on schedule even if sufficient escrow funds are not
available. The servicer will be reimbursed by the mortgage owner or from
liquidation proceeds for payments advanced that the
 
                                       12
<PAGE>   14
 
servicer is unable to recover from the mortgagor, although the timing of such
reimbursement is typically uncertain. In the interim, the servicer must absorb
the cost of funds advanced. Further, the servicer must bear the costs of
attempting to collect on delinquent and defaulted loans. We do not collect
servicing income from the time a loan becomes delinquent until foreclosure, at
which time such amounts, if any, may be recovered.
 
     IF THERE ARE ADVERSE CONDITIONS IN ONE GEOGRAPHIC AREA OR WITH A FEW
CUSTOMERS, THESE MAY HAVE A DISPROPORTIONATELY LARGE EFFECT ON OUR FINANCIAL
RESULTS.
 
     Historically, our single-family mortgage loan portfolio has been
concentrated in certain geographic regions, particularly Michigan, based upon
the location of the property collateralizing the mortgage loan. Because
borrowers of single-family mortgage loans usually reside on the collateral
property, changes in economic and business conditions in the area in which the
property is located can affect the borrower and thus have an effect on the
performance of the loan. For instance, the mortgage loans we serviced (as
measured by unpaid principal balance), including loans held for investment, that
were collateralized by property located in Michigan comprised 22.4% of total
mortgage loans at December 31, 1998. As a result, unfavorable or worsened
economic conditions in Michigan could have a material adverse effect on our
financial condition and results of operations.
 
     In addition to risks associated with a geographic concentration of our loan
portfolio, our results of operations can be affected by concentration of credit
to just a few borrowers. We currently provide warehouse lines of credit ranging
up to $21.5 million to certain mortgage companies. We have also originated
commercial real estate loans in amounts up to $6.5 million. Repayment of such
loans is primarily dependent upon the successful operation of the business
involved and therefore could be subject to a greater extent to adverse
conditions in the economy. If any single large loan customer defaults on their
loan from us, it could adversely affect our operating results.
 
     A SIGNIFICANT PORTION OF OUR INCOME ARISES FROM THE MORTGAGE BANKING
BUSINESS, WHICH IS SEASONAL.
 
     We earn a significant amount of income in the mortgage banking industry,
which is generally subject to seasonal variations. These variations reflect the
general national pattern of sales and resales of homes, although refinancings
tend to be less seasonal and more closely related to changes in interest rates.
Sales and resales of homes typically peak during the spring and summer seasons
and decline to lower levels from mid-November through February. In addition,
delinquency rates typically rise in the winter months, which results in higher
servicing costs. The magnitude of these variations, which is beyond our control,
could adversely affect our operating results.
 
     THE EXPANSION OF OUR RETAIL BANKING BUSINESS WILL BE EXPENSIVE.
 
     We intend to expand our retail banking operations through the acquisition
or establishment of additional bank branches. This expansion is expected to
occur in communities across southern and western Michigan. If we are unable to
generate a customer base within these communities because of consumer loyalty to
other financial institutions or for other reasons, we will have incurred
construction or building acquisition costs and liabilities under lease
agreements as well as related branch overhead expenses without an appropriate
return on our investment.
 
     WE ARE DEPENDENT ON OUR KEY PERSONNEL.
 
     Our growth and development to date have been largely dependent on certain
key employees, the loss of whom could have a material adverse effect. Our key
employees are Thomas J. Hammond, Chief Executive Officer; Mark T. Hammond,
President; Michael W. Carrie, Executive Vice President and Chief Financial
Officer; and Joan H. Anderson, Executive Vice President. Each of these persons
are officers of the Company and the Bank. Our key employees also include
 
                                       13
<PAGE>   15
 
Kirstin A. Hammond, Executive Vice President; and Robert O. Rondeau, Jr.,
Executive Vice President, who are officers of the Bank. We do not carry "key
person" life insurance on the lives of any officers.
 
     WE ARE IMPACTED BY COMPETITION FROM MANY OTHERS.
 
     Both our retail banking business and mortgage banking business are
extremely competitive. In the retail banking segment, we will have to overcome
historical relationships to attract customers away from our competition. In the
mortgage banking segment, many of our competitors are, or are affiliates of,
enterprises that have greater resources than we do.
 
     Through our various businesses, we compete with different institutions,
including:
 
     - mortgage companies;
 
     - other banks and thrift institutions;
 
     - credit unions;
 
     - full service and discount broker dealers;
 
     - investment companies, mutual funds and money market funds; and
 
     - insurance companies.
 
     Some of our competitors are not regulated as extensively as we are and,
therefore, may have greater flexibility in competing for business. Some of these
competitors are subject to similar regulation but have the advantages of
established customer bases, higher lending limits, extensive branch networks,
numerous automated teller machines or other factors. We compete by offering
market rates on our products and prompt service to our customers.
 
     WE OPERATE A BUSINESS THAT IS SUBJECT TO SIGNIFICANT GOVERNMENT REGULATION.
 
     We are subject to extensive regulation by state and federal banking
authorities. These regulations govern our existence, our general operations and
our other functions such as mortgage origination, processing, underwriting,
selling and servicing. Many of these regulations are intended to protect
depositors, the public or the FDIC and not our shareholders. Regulatory
requirements will affect our lending practices, capital structure, investment
practices, dividend policy and growth. Any change in these regulatory
requirements could adversely affect us. In some instances, regulatory changes
are applied retroactively. Our mortgage banking operations are also affected by
the rules and regulations of quasi-governmental agencies that purchase,
guarantee or insure mortgage loans. Further, federal economic and monetary
policies, which are entirely out of our control, will affect various aspects of
our operations.
 
     In addition, certain states require that interest be paid to mortgagors on
funds deposited by them in escrow to cover mortgage-related payments such as
property taxes and insurance premiums. Federal legislation has been introduced
in the past that would, if enacted, revise current escrow regulations and
establish a uniform escrow calculation methodology in all states. If such
federal legislation were enacted or if other states enact legislation relating
to payment of, or increases in the rate of, interest on escrow balances, or if
such legislation were retroactively applied to loans in our servicing portfolio,
our earnings would be adversely affected.
 
     WE OPERATE A BUSINESS IN AN INDUSTRY THAT HAS BEEN SUBJECT TO SIGNIFICANT
LITIGATION.
 
     In recent years, mortgage originators have been subject to class action
lawsuits that allege violations of federal and state laws and regulations,
including the propriety of collecting and paying various fees and charges and
the calculation of escrow amounts. Class action lawsuits may continue to be
filed in the future against mortgage originators generally. The results of our
operations could be adversely affected if we suffer an unfavorable court
judgment in any such lawsuit.

     WE MAY INCUR SIGNIFICANT COSTS IF WE FORECLOSE ON ENVIRONMENTALLY
CONTAMINATED REAL ESTATE.
 
     If we foreclose on a defaulted mortgage loan to recover our investment in
such mortgage loan, we may be subject to environmental liabilities in connection
with the underlying real property. These liabilities could exceed the fair value
of the real property. It is also possible that hazardous substances or wastes,
contaminants, pollutants or their sources (as defined by state and federal laws
and regulations) may be discovered on properties during our ownership or after
they are sold to a third party. If they are discovered on a property that we
have acquired through foreclosure or otherwise, we may be required to remove
those substances and clean up the property. We may have to pay for the entire
cost of any removal and clean-up without the contribution of any other third
parties. These costs may also exceed the fair value of the property. We may also
be liable to tenants and other users of neighboring properties. In addition, we
may find it difficult or impossible to sell the property prior to or following
any such clean-up.
 
     THE YEAR 2000 PROBLEM MAY HAVE AN ADVERSE IMPACT ON US OR ON OTHERS UPON
WHOM WE DEPEND.
 
     Much of today's information technology (i.e., computer systems) and
embedded technology (e.g., microcontrollers) identifies a particular year on the
basis of the last two digits of that year. For example, the year "1998" is
recognized by the digits "98." The inability of information technology and
embedded technology to properly recognize a year that begins with "20" instead
of "19," if not corrected, may result in the production of erroneous results or
the failure of systems which rely on information technology and embedded
technology. This failure of systems, production of erroneous results and the
resulting damages is commonly known as the "Year 2000 Problem" or the "Y2K
Problem."
 
     We are dependent, to a substantial degree, upon the proper functioning of
our computer systems as well as those of our vendors, suppliers and customers.
Most of our products and services rely on information and data provided by
others. Most of this information and data is provided electronically and is
dependent on information systems and telecommunications. The inability of our
vendors and suppliers to provide accurate information in a timely manner, our
inability to accurately and timely process such information, the inability of
our customers to receive and use our products and services, and a general
disruption of telecommunications and utilities as a result of the Year 2000
Problem would most likely result in business interruption or shutdown, financial
loss, potential regulatory action, harm to our reputation and potential legal
liability.
 
     Although we have conducted internal development and testing of our computer
systems to insure millennium compliance, we can give no assurance that our
internal systems will be completely free of errors. Furthermore, we can give no
assurance that all of our vendors will deliver Year 2000 compliant certificates
or that the vendors will in fact be Year 2000 compliant despite their
certification of compliance. If either our computer systems or those of our
vendors fail to function properly because of the Year 2000 problem, the results
of our operations may materially suffer.

                                  THE OFFERING
 
Preferred Securities
Issuer.....................  Flagstar Trust
 
Securities Offered.........  Flagstar Trust is offering 2,600,000 of its
                             Preferred Securities, which represent an indirect
                             interest in our Junior Subordinated Debentures that
                             it will purchase with the proceeds of this
                             offering.
 
                             Flagstar Trust will sell its Preferred Securities
                             to the public and its Common Securities to us.
                             Together, the Preferred Securities and the Common
                             Securities are referred to as Trust Securities.
                             Flagstar Trust will use the proceeds from the sale
                             of Trust Securities to buy our      % Junior
                             Subordinated Debentures which will have the same
                             payment terms as the Preferred Securities.
 
Use of Proceeds of Sale of
the Preferred Securities...  The proceeds of the sale of the Preferred
                             Securities will be invested by Flagstar Trust in
                             our Junior Subordinated Debentures. We will receive
                             the proceeds from the issuance of the Junior
                             Subordinated Debentures. We intend to:
 
                             - invest a significant portion of the net proceeds
                               in the Bank; and
 
                             - retain the remainder for our general corporate
                               purposes.
 
Quarterly Distributions Are
Payable to You on the
Preferred Securities.......  The Distributions payable on each Preferred
                             Security will:
 
                             - be fixed and accumulate at a rate per year of
                                    %;
 
                             - accrue from the date of issuance of the Preferred
                               Securities; and
 
                             - be payable after each calendar quarter on the
                               last business day of March, June, September and
                               December of each year that the Preferred
                               Securities are outstanding, beginning on June 30,
                               1999.
 
Flagstar Bancorp and
Flagstar Trust May Defer
Distributions to You on the
Preferred Securities.......  Flagstar Trust may defer Distributions on the
                             Preferred Securities if we defer paying interest to
                             Flagstar Trust on the Junior Subordinated
                             Debentures. We generally have the right to defer
                             interest payments on the Junior Subordinated
                             Debentures for up to 20 consecutive quarters.
                             During any deferral period, you will accumulate
                             Distributions at the annual rate of      %, plus
                             you will earn additional interest at the annual
                             rate of      %, compounded quarterly, on any unpaid
                             Distributions.
 
You Will Still be Taxed
Even If Distributions on
the Preferred Securities
are Deferred...............  If Distributions on the Preferred Securities are
                             deferred, you must still include the related income
                             in your taxable gross income for United States
                             federal income tax purposes for as long
                                       16
<PAGE>   18
 
                             as the Junior Subordinated Debentures remain
                             outstanding. As a result, you may incur a tax
                             liability on the income before you have received
                             cash to pay the tax. For further information on
                             deferrals and their tax consequences, see "Risk
                             Factors -- Distributions on the Preferred
                             Securities may be deferred; you may have to include
                             interest in your taxable income before you receive
                             cash," "Description of the Junior Subordinated
                             Debentures -- Option to Extend Interest Payment
                             Period" and "United States Federal Income Tax
                             Consequences -- Potential Extension of Interest
                             Payment Period and Original Issue Discount."
 
You Will Be Required to
Sell Your Preferred
Securities To Flagstar
Trust When the Junior
Subordinated Debentures
Mature or if They Are
Prepaid....................  The Junior Subordinated Debentures will mature on
                                         , 2029. You will be required to sell
                             your Preferred Securities to Flagstar Trust upon
                             the stated maturity date of the Junior Subordinated
                             Debentures or earlier if they are prepaid. If we
                             prepay the Junior Subordinated Debentures, Flagstar
                             Trust will simultaneously redeem your Preferred
                             Securities on the date of payment of the Junior
                             Subordinated Debentures.
 
If the Junior Subordinated
Debentures Are Prepaid,
Your Preferred Securities
Will Be Redeemed...........  If we receive prior approval of federal banking
                             regulators, if required, we may prepay the Junior
                             Subordinated Debentures prior to maturity:
 
                             - on or after             , 2004; or
 
                             - at any time if certain specified events occur
                               that may have a significant adverse effect on our
                               benefits of having the Preferred Securities
                               outstanding.
 
                             Upon any prepayment of the Junior Subordinated
                             Debentures, your Preferred Securities will be
                             redeemed at the liquidation amount of $25 per
                             Preferred Security plus any accrued and unpaid
                             Distributions to the date of redemption. For
                             further information on redemptions, see
                             "Description of the Preferred
                             Securities -- Redemption" and "Description of the
                             Junior Subordinated Debentures Redemption."
 
At our Option, We May
Require You to Exchange
Your Preferred Securities
For Our Junior Subordinated
Debentures.................  We have the right at any time to dissolve or
                             liquidate Flagstar Trust and distribute the Junior
                             Subordinated Debentures to you in exchange for your
                             Preferred Securities. If that happens, you will
                             receive Junior Subordinated Debentures in exchange
                             for the same principal amount of your holdings of
                             Preferred Securities. However, we must pay the
                             creditors of Flagstar Trust and, if required,
                             receive prior approval of federal banking
                             regulators
                                       17
<PAGE>   19
 
                             before we dissolve or liquidate Flagstar Trust. If
                             the Junior Subordinated Debentures are distributed,
                             we will use our best efforts to list them on The
                             Nasdaq Stock Market(R) in place of the Preferred
                             Securities. For further information concerning
                             distribution of the Junior Subordinated Debentures,
                             see "Description of the Preferred
                             Securities -- Distribution of Junior Subordinated
                             Debentures."
 
We Fully and
Unconditionally Guarantee
Your Preferred Securities
On a Subordinated Basis....  We fully and unconditionally guarantee the payment
                             of all distributions Flagstar Trust is obliged to
                             make, but only to the extent Flagstar Trust has
                             sufficient funds to satisfy those payments.
 
                             If we do not make a payment on the Junior
                             Subordinated Debentures, Flagstar Trust will not
                             have sufficient funds to make payments on the
                             Preferred Securities. The Guarantee does not
                             require us to make any payments on our Junior
                             Subordinated Debentures nor does it require us to
                             make up any shortfall in Flagstar Trust's funds
                             needed to make a payment on the Preferred
                             Securities to you. The Guarantee only requires us
                             to make payments to the extent Flagstar Trust holds
                             any funds.
 
                             For further information concerning our Guarantee of
                             the Preferred Securities, see "Description of
                             Guarantee."
 
Your Preferred Securities
Rank Lower in Payment
Compared to Our Other
Obligations................  Our obligations under the Preferred Securities
                             Guarantee, the Junior Subordinated Debentures and
                             other governing documents are unsecured and have a
                             payment priority below all of our current and
                             future Senior and Subordinated Debt. In addition,
                             because we are a holding company that relies on our
                             subsidiaries for virtually all of our income, all
                             existing and future liabilities of our subsidiaries
                             will effectively rank higher than all of our
                             obligations relating to the Preferred Securities
                             and the Junior Subordinated Debentures. For
                             example, our Bank currently has a subsidiary that
                             acts as a real estate investment trust and sold
                             preferred shares to the public. If the Bank is
                             required to terminate the REIT, the REIT's
                             preferred shares will be exchanged for the Bank's
                             preferred shares. If this happens, the Bank's funds
                             would be used to first satisfy its obligations on
                             its own preferred shares before paying any
                             dividends to the Company.
 
                             There is no limit on the amount of other preferred
                             securities or other junior subordinated debentures
                             that we may issue in the future or on the amount of
                             future liabilities of the Bank. Future issuances of
                             securities similar to the Preferred Securities and
                             the Junior Subordinated Debentures will rank
                             equally with our obligations under the Junior
                             Subordinated Debentures and our Preferred
                             Securities Guarantee described in this Prospectus.

You Will Have Limited
Voting Rights..............  As a holder of Preferred Securities, you will have
                             limited voting rights. These rights relate only to
                             the dissolution or termination of Flagstar Trust
                             and removal of the Property Trustee and the
                             Indenture Trustee of Flagstar Trust under certain
                             conditions. See "Description of the Preferred
                             Securities -- Voting Rights; Amendment of the Trust
                             Agreement."
 
The Preferred Securities
Will Be In Book Entry Form
Only.......................  You will not receive a certificate for your
                             Preferred Securities. Instead, the Preferred
                             Securities will be represented by a global security
                             that will be deposited with and registered in the

The Nasdaq Stock
Market(R)..................  Flagstar Trust has applied to have the Preferred
                             Securities listed for trading on The Nasdaq Stock
                             Market(R) under the trading symbol
                             "               ." Prior to this offering, there
                             has been no public market of the Preferred
                             Securities. The Underwriters have advised Flagstar
                             Trust that they presently intend to make a market
                             in the Preferred Securities prior to the
                             commencement of trading on The Nasdaq Stock
                             Market(R). The Underwriters are not obligated to
                             make a market in the Preferred Securities, however,
                             and may cease market making activities at any time.
                             We can not give any assurance as to the liquidity
                             of any trading market for the Preferred Securities.

                                USE OF PROCEEDS
 
     All of the proceeds from the sale of Preferred Securities by Flagstar Trust
will be invested in the Junior Subordinated Debentures. The net proceeds to
Flagstar Bancorp from the sale of the Junior Subordinated Debentures, after
deducting underwriting commissions and estimated offering expenses, will be
approximately $64,500,000 or $74,250,000 if the underwriters' over-allotment
option is exercised in full. We intend to invest a significant portion of the
net proceeds in the Bank, with the remainder to be retained by us and used for
general corporate purposes.

                                    BUSINESS
 
     GENERAL. We are one of the largest home mortgage lenders in the United
States. Our business is the origination of single-family mortgage loans. Through
our Bank, we attract deposits from the general public and originate or acquire
residential mortgage loans. The Bank is the largest independent savings
institution in Michigan based on asset size. We also acquire funds on a
wholesale basis from a variety of sources, service a significant volume of
mortgage loans for others, and to a lesser extent, make consumer loans,
commercial real estate loans and non-real estate commercial loans. For the year
ended December 31, 1998, we ranked 13th in the United States in residential
mortgage loan originations.
 
     We have experienced significant asset growth and achieved continuing
profitability: our total assets increased to $3.0 billion for the year ended
December 31, 1998 from $1.9 billion for the same period in 1997 and $1.3 billion
for the same period in 1996; our net income increased to $41.1 million ($2.90
per share -- diluted), for the year ended December 31, 1998 from $21.8 million
($1.68 per share -- diluted) for the same period in 1997 and $17.0 million
($1.51 per share -- diluted) for the same period in 1996; and for the year ended
December 31, 1998 return on average assets equaled 1.45% and return on average
equity was 28.77% compared to return on average assets of 1.29% and return on
average equity of 20.69% for the same period in 1997.
 
     MORTGAGE AND RETAIL BANKING. Our primary lines of business are mortgage
banking and retail banking. A majority of our revenue (net interest income and
non-interest income) and earnings before income taxes is attributable to the
mortgage banking segment. We believe that our retail banking business provides
us with access to attractive and relatively stable funding sources for our
mortgage origination business. We believe we have a strategic advantage compared
to other mortgage originators with no retail banking operations due to our
stable, lower cost of funds.
 
     Mortgage Banking. Our mortgage banking operations originate residential
mortgages through 31 retail loan origination offices located in Michigan (27),
Florida (3) and Ohio (1). In addition, we originate mortgage loans on a
wholesale basis through a nationwide network of independent mortgage brokers. We
also purchase mortgage loans on a regular basis from independent mortgage
lenders, commercial banks, savings and loan associations and other financial
institutions with whom we are familiar. These independent mortgage brokers and
mortgage lenders originate such loans using our underwriting standards. We
service this network through over 60 account executives, who are organized among
10 regional wholesale/correspondent lending offices and five
wholesale/correspondent satellite offices.
 
     Retail Banking. We provide a full range of retail banking services to
consumers and small businesses in southern and western Michigan. We currently
operate a network of 30 bank branches (including nine opened in 1998 and two in
1999) located in southern and western Michigan counties. Since 1994, we have
focused on expanding our branch network in these markets in order to increase
our access to retail deposit funding sources. We believe that this also provides
a greater opportunity for cross-marketing of consumer banking services to our
large base of mortgage customers in Michigan. We believe we can benefit from the
customer displacement in our markets caused by the substantial consolidation of
the banking industry in Michigan.
 
     LOAN PRODUCTION. For the year ended December 31, 1998, we produced $18.8
billion in mortgage loans. These included $17.4 billion in mortgage loans
produced through the wholesale and correspondent network and $1.4 billion
originated through the retail network. We produced mortgage loans of $7.9
billion during 1997 which included $7.1 billion produced through the wholesale
and correspondent network and $745.2 million originated through the retail
network. For the year ended December 31, 1996, the wholesale and correspondent
network produced $6.1 billion and the retail network originated $685.3 million
for a total production of $6.8 billion.

<PAGE>   24
 
     LOAN SALES AND SERVICING. We sell a substantial portion of our loan
production into the secondary market. These sales are principally completed by
securitizing pools of loans through programs offered by government-sponsored
enterprises such as Fannie Mae, Freddie Mac, and Ginnie Mae and through sales to
private investors. We generally retain the servicing rights to many of the loans
that we sell. We also realize additional income by selling servicing rights on
an individual and a bulk basis to other mortgage servicers. Our loan servicing
portfolio totaled $11.5 billion at December 31, 1998, $6.4 billion at December
31, 1997 and $4.8 billion at December 31, 1996 (net of loans subserviced for
others).
 
     TECHNOLOGY. We make extensive use of advanced technology and automated
processes which we believe enhance our competitiveness and reduce the cost of
our mortgage origination operations. We were one of the first major mortgage
lenders to utilize video conferencing for loan production. In 1996, we began
full-scale operational use of automated underwriting system technologies,
including Fannie Mae's Desktop Underwriter ((TM)) and Freddie Mac's Loan
Prospector (TM). In fact, we are currently one of the largest users of the Loan
Prospector (TM) system. We underwrite substantially all of our mortgage loans
using these automated systems. We believe that our use of these systems reduces
overhead, enhances customer service and better ensures that our mortgage loans
conform to secondary market guidelines.
 
     BUSINESS STRATEGY. Our strategy consists of the following key elements:
 
     - continue to expand our bank branch network into demographically desirable
       communities in Michigan in order to gain access to additional retail
       funding sources;
 
     - as market conditions permit, retain a portion of our mortgage loan
       production volume or mortgage servicing rights or both (thereby
       benefiting from economies of scale);
 
     - continue to utilize advanced technology and automated processes
       throughout our business to improve customer service, reduce costs of loan
       production and servicing and increase efficiencies; and
 
     - cross-sell retail banking services to our large Michigan base of existing
       mortgage customers.
 
                              ACCOUNTING TREATMENT
 
     For financial reporting purposes, we will treat Flagstar Trust as our
subsidiary. Accordingly, we will include the accounts of Flagstar Trust in our
consolidated financial statements. We will include the Preferred Securities in
debt in our consolidated statements of financial condition, and will include
appropriate disclosures about the Preferred Securities, the Guarantee and the
Junior Subordinated Debentures in the notes to our consolidated financial
statements. For financial reporting purposes, we will record Distributions on
the Preferred Securities as interest expense in our consolidated statements of
earnings.

the Trust Indenture Act of 1939 (the "Trust Indenture Act"). This summary is not
complete and is subject to, and is qualified in its entirety by reference to,
all the provisions of the Trust Agreement, including the definitions portion of
the Trust Agreement, and the Trust Indenture Act. However, we believe that all
material terms of the Preferred Securities in the Trust Agreement are set forth
in this section of the Prospectus. The form of the Trust Agreement has been
filed as an exhibit to the Registration Statement. This Prospectus is a part of
the Registration Statement.
 
GENERAL
 
     The Administrative Trustees on behalf of Flagstar Trust will issue the
Preferred Securities and the Common Securities (collectively, the "Trust
Securities"). We will own 100% of the Common Securities and you may purchase the
Preferred Securities. The Preferred Securities will represent undivided
preferred beneficial interests in the assets of Flagstar Trust and each holder
will be entitled to a preference in respect of certain distributions by Flagstar
Trust and amounts payable on redemption or liquidation of Flagstar Trust.
Otherwise, the Preferred Securities will generally rank the same as the Common
Securities.
 
     The Preferred Securities, as well as the Junior Subordinated Debentures,
are scheduled to mature on                            , 2029.
 
     The Property Trustee will hold the Junior Subordinated Debentures which we
have issued in trust for the benefit of the holders of Trust Securities. Our
Guarantee (the "Guarantee") will be subordinated to most of our other
obligations and liabilities. Our Guarantee will not provide for the payment of
Distributions (as defined below) or amounts payable on redemption of the
Preferred Securities if Flagstar Trust does not have funds available to make
such payments. See "Description of Guarantee."
 
     If we do not make required payments on the Junior Subordinated Debentures
held by Flagstar Trust, taking into account our right to defer such payments for
up to 20 quarters, Flagstar Trust will be unable to pay any Distributions to
you. In such event, you may make a claim directly against us to enforce payment
of the amounts due to you. See "Description of the
                                       24
<PAGE>   26
 
Junior Subordinated Debentures -- Enforcement of Certain Rights by Holders of
Preferred Securities."
 
DISTRIBUTIONS
 
     Distributions on the Preferred Securities will be fixed at an annual rate
of      % of the Liquidation Amount of $25 per Preferred Security. Unpaid
Distributions that are past due will accumulate additional interest at an annual
rate of      % of the unpaid Distributions, compounded quarterly. The term
"Distribution" includes any additional amounts payable in respect of
Distributions unless otherwise stated.
 
     Distributions on the Preferred Securities:
 
     - will be cumulative,
 
     - will accumulate from             , 1999, the date of initial issuance of
       the Preferred Securities, and
 
     - will be payable quarterly in arrears on the last Business Day of March,
       June, September and December, commencing June 30, 1999.
 
     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 a Distribution is payable is not a Business Day, the payment of that
Distribution will generally be made on the next Business Day (and without any
additional interest). "Business Day" means any day other than a Saturday or a
Sunday, or a day on which banking institutions in the State of Michigan 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 Indenture
Trustee is closed for business.
 
     We may defer the payment to Flagstar Trust of interest on the Junior
Subordinated Debentures at any time for one or more Extension Periods. However,
we may not defer any payments if we are in default under the Indenture. No
Extension Period may extend beyond the maturity date of the Junior Subordinated
Debentures. If we elect to defer the payment of interest, then quarterly
Distributions on the Preferred Securities will be deferred by Flagstar Trust
during the Extension Period. The Distributions will continue to accumulate, with
additional interest, generally at an annual rate of      %, compounded
quarterly, during the Extension Period.
 
     During any Extension Period:
 
     - we may not declare or pay any dividends on, make any distribution, or
       redeem, purchase, acquire or make a liquidation payment on any of
       Flagstar Bancorp's capital stock; and
 
     - we may not make any payment of interest, principal or premium on or
       repay, repurchase or redeem any debt securities issued by us that rank
       equal or junior to the Junior Subordinated Debentures (of which there are
       none at the time of this printing), or make any guarantee payments on the
       foregoing.
 
     The Extension Period restrictions do not apply to:
 
     - repurchases, redemptions or other acquisitions of shares of our capital
       stock in connection with any employment contract, benefit plan or other
       similar arrangement with or for the benefit of any one or more employees,
       officers, directors or consultants, or a dividend reinvestment or
       shareholder stock purchase plan;
 
     - any declaration of a dividend in connection with any shareholders' rights
       plan, or the issuance of rights, stock or other property under any
       shareholders' rights plan, or the redemption or repurchase of rights
       pursuant to the plan;
 
                                       25
<PAGE>   27
 
     - any dividend in the form of stock, warrants, options or other rights
       where the dividend or the stock issuable upon exercise of the warrants,
       options or other rights is the same stock as that on which the dividend
       is being paid or ranks equal or junior to that stock; or
 
     - payments by us under the Guarantee.
 
     When we pay all the accumulated amounts due to you during an Extension
Period, the Extension Period will terminate. However, we have the right to begin
another Extension Period under the same terms outlined above. There is no limit
on the number of times we can elect to begin an Extension Period. In no way may
any single Extension Period extend beyond 20 consecutive calendar quarters.
 
     We have no current intention of exercising our right to defer payments of
interest by extending the interest payment period on the Junior Subordinated
Debentures.
 
REDEMPTION
 
     When we repay or redeem some or all of the Junior Subordinated Debentures,
whether at maturity or upon earlier redemption, the Property Trustee will apply
the proceeds from the repayment or redemption to redeem the same proportionate
amount of Preferred Securities and Common Securities. The Redemption Price per
Security will equal the $25 Liquidation Amount, plus accumulated and unpaid
Distributions to the date of redemption. We will make this redemption not less
than 30 nor more than 60 days after the notice of a date of redemption (the
"Redemption Date"), at the Redemption Price (as defined below). See "Description
of the Junior Subordinated Debentures -- Redemption."
 
     If less than all the Junior Subordinated Debentures are to be repaid or
redeemed, then the aggregate liquidation amount of Preferred and Common
Securities to be redeemed will be allocated approximately 3% to the Common
Securities and 97% to the Preferred Securities, except in the case of an event
of default under the Indenture. See "-- Subordination of Common Securities."
 
     We will have the right, after receipt of prior approval by federal banking
regulators, if approval is then required, to redeem the Junior Subordinated
Debentures:
 
     - on or after             , 2004, in whole at any time or in part from time
       to time; or
 
     - prior to             , 2004 in whole, but not in part, at any time within
       90 days following the occurrence and continuation of a Tax Event, an
       Investment Company Event or a Capital Treatment Event, each as we defined
       below. See "Description of the Junior Subordinated Debentures -- Optional
       Redemption."
 
SELECTED DEFINITIONS
 
     "Additional Sums" means the additional payments we are required by the
Indenture to make under the Junior Subordinated Debentures to cover certain
charges imposed upon Flagstar Trust so that the funds available to Flagstar
Trust for payment of Distributions will not be reduced. An example of the
Additional Sums could be any additional taxes, duties and other governmental
charges that Flagstar Trust has incurred.
 
     "Capital Treatment Event" means that we have received an opinion of
nationally recognized independent counsel experienced in such matters that, as a
result of
 
     (1) any amendment to, clarification of or change, including any announced
         prospective change, in applicable laws or regulations or official
         interpretations thereof or policies with respect thereto; or
 
                                       26
<PAGE>   28
 
     (2) any official administrative pronouncement or judicial decision
         interpreting or applying such laws or regulations, which amendment,
         clarification, change, pronouncement or decision is announced or is
         effective after the date of this Prospectus,
 
there is more than an insubstantial risk that the Preferred Securities will not
then constitute capital of Flagstar Bancorp for purposes of the capital adequacy
guidelines or policies of federal banking regulators. There are currently no
capital adequacy guidelines applicable to savings and loan holding companies
such as Flagstar Bancorp.
 
     "Investment Company Event" means that the Administrative Trustees have
received an opinion of nationally recognized independent counsel experienced in
such matters that, as a result of the occurrence of a change, including any
announced prospective change, in law or regulation or a written change,
including any announced prospective change, in interpretation or application of
law or regulation by any legislative body, court, governmental agency or
regulatory authority on or after the date of this Prospectus, there is more than
an insubstantial risk that Flagstar Trust is or will be considered an
"investment company" that is required to be registered under the Investment
Company Act of 1940, as amended (the "Investment Company Act").
 
     "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 Junior 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 Junior Subordinated Debentures to holders of Trust Securities in
connection with a dissolution or liquidation of Flagstar Trust, Junior
Subordinated Debentures having a principal amount equal to the Liquidation
Amount of Trust Securities of each holder to whom such Junior Subordinated
Debentures are distributed.
 
     "Liquidation Amount" means the stated amount of $25 per Trust Security. The
Liquidation Amount is the amount that you are entitled to receive if Flagstar
Trust is terminated at or prior to the maturity date and its assets are
distributed to the holders of its securities. You are entitled to receive this
amount from the assets of Flagstar Trust for distribution, after it has paid
liabilities owed to its creditors, if Flagstar Trust has sufficient funds to pay
this amount.
 
     "Redemption Price" means, with respect to any Trust Security, the
Liquidation Amount of such Trust Security, plus accumulated and unpaid
Distributions to the Redemption Date, allocated on a pro rata basis (based on
Liquidation Amounts) among the holders of Trust Securities.
 
     "Tax Event" means that the regular trustees, or, if Flagstar Trust has been
terminated at the time, an appropriate representative of the holders of the
Junior Subordinated Debentures, have received an opinion of nationally
recognized independent tax counsel experienced in such matters to the effect
that, as a result of:
 
     - any amendment to, clarification of, or change, including any announced
       prospective change, in the laws, or any regulations under the laws, of
       the United States or any political subdivision or taxing authority
       affecting taxation;
 
     - any judicial decision, official administrative pronouncement, ruling,
       regulatory procedure, notice or announcement, including any notice or
       announcement of intent to adopt such procedures or regulations (an
       "Administrative Action"); or  -- any amendment to, clarification of, or
       change in the official position or the interpretation of such
       Administrative Action or judicial decision that differs from the prior
       generally accepted position,
 
in each case, by any legislative body, court, governmental authority or
regulatory body, irrespective of the manner in which the amendment,
clarification, change or Administrative Action is made known, which amendment,
clarification, change or Administrative Action is effective or
 
                                       27
<PAGE>   29
 
which pronouncement or decision is announced, in each case, on or after the date
of this Prospectus, there is more than an insubstantial risk that:
 
     (1) Flagstar Trust is, or will be within 90 days of the date of the opinion
         of counsel, subject to United States federal income tax with respect to
         income accrued or received on the Junior Subordinated Debentures,
 
     (2) Flagstar Trust is, or will be within 90 days of the date of the opinion
         of counsel, subject to more than a de minimis amount of taxes, duties
         or other governmental charges, except for withholding taxes, or
 
     (3) interest paid in cash by us to Flagstar Trust on the Junior
         Subordinated Debentures is not, or within 90 days of the date of the
         opinion of counsel will not be, deductible, in whole or in part, by us
         for United States federal income tax purposes.
 
     Notwithstanding the foregoing, a Tax Event does not include any change in
tax law that requires us to defer taking a deduction for any original issue
discount that accrues with respect to the Junior Subordinated Debentures until
the interest payment related to the OID is paid by us in cash if the change in
tax law does not create more than an insubstantial risk that we will be
prevented from taking a deduction for OID accruing on the Junior Subordinated
Debentures at a date that is no later than the date the interest payment related
to the OID is actually paid by us in cash.
 
     If any event described in clause (1) or (2) of the definition of "Tax
Event" above has occurred and is continuing and Flagstar Trust is the holder of
all of the Junior Subordinated Debentures, Flagstar Bancorp will pay Additional
Sums, if any, on the Junior Subordinated Debentures.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES
 
     We may at any time elect to dissolve Flagstar Trust and, after we have paid
all of the liabilities of creditors of Flagstar Trust as provided by applicable
law, cause the Junior Subordinated Debentures to be distributed to you. However,
we may only dissolve Flagstar Trust if we have received prior federal banking
regulators' approval, if then required. If we dissolve Flagstar Trust and
distribute the Junior Subordinated Debentures to you:
 
     - the Preferred Securities will no longer be outstanding;
 
     - the Depositary or its nominee, as the record holder of the Preferred
       Securities, will, upon the distribution of the Junior Subordinated
       Debentures, receive a registered global certificate or certificates
       representing the Junior Subordinated Debentures; and
 
     - any certificates representing Preferred Securities not held by the
       Depositary or its nominee will be deemed to represent the Junior
       Subordinated Debentures having a principal amount equal to the
       Liquidation Amount of the Preferred Securities.
 
     The Preferred Securities certificates will continue to bear interest until
the certificates are presented to the Administrative Trustees or their agent for
replacement by certificates representing an equal amount of Junior Subordinated
Debentures, at which time only unpaid interest will be paid, if Flagstar Trust
has sufficient funds available.
 
REDEMPTION PROCEDURES
 
     Flagstar Trust may not redeem fewer than all of the outstanding Preferred
Securities unless it has paid all accumulated and unpaid Distributions on all
Preferred Securities for all quarterly distribution periods terminating on or
prior to the date of redemption. Flagstar Trust will only redeem the Preferred
Securities if we have redeemed the Junior Subordinated Debentures. Flagstar
Trust may redeem Preferred Securities only in an amount equal to the funds it
has on
 
                                       28
<PAGE>   30
 
hand and legally available to pay the Redemption Price. See "-- Subordination of
Common Securities" and "Description of Guarantee."
 
     Unless there is a payment default, additional interest will stop accruing
on those Preferred Securities called for redemption on the date they are called
for redemption.
 
     The Property Trustee will give you notice of the redemption at least 30 but
not more than 60 days before the date fixed for redemption. If Flagstar Trust
gives a notice of redemption, then, by 12:00 noon, New York City time, on the
date of redemption, if the funds are available for payment, the Property Trustee
will, for Preferred Securities held in book-entry form:
 
     - deposit irrevocably with The Depository Trust Company ("DTC") funds
       sufficient to pay the Redemption Price; and
 
     - give DTC irrevocable instructions and authority to pay the Redemption
       Price to the holders of the Preferred Securities.
 
     With respect to Preferred Securities not held in book-entry form, if funds
are available for payment, the Property Trustee will:
 
     - irrevocably deposit with the paying agent for the Preferred Securities
       funds sufficient to pay the Redemption Price; and
 
     - give such paying agent irrevocable instructions and authority to pay the
       Redemption Price to the holders of Preferred Securities upon surrender of
       their certificates evidencing the Preferred Securities.
 
     Notwithstanding the foregoing, distributions payable on or prior to the
date of redemption for any Preferred Securities called for redemption will be
payable to the holders on the relevant record dates.
 
     Once notice of redemption is given and funds are deposited as required,
then all rights of the holders of Preferred Securities called for redemption
will cease, except the right to receive the Redemption Price, but without
interest after the date of redemption. At that time, those Preferred Securities
will cease to be outstanding.
 
     Payment of the Redemption Price on the Preferred Securities and any
distribution of Junior Subordinated Debentures to holders of Preferred
Securities will be made to the applicable record holders on the relevant record
date, which date will 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 will be a date at least 15 days prior to the
redemption date or liquidation date, as applicable. In the case of a
liquidation, the record date will be no more than 45 days before the liquidation
date.
 
     If any date fixed for redemption is not a Business Day, then payment of the
Redemption Price will be made on the next day that is a Business Day, without
any interest or other payment for the delay. If the next Business Day falls in
the next calendar year, the payment will instead be made on the immediately
preceding Business Day.
 
     If payment of the Redemption Price for the Preferred Securities called for
redemption is improperly withheld or refused and not paid, either by Flagstar
Trust or by Flagstar Bancorp under the Guarantee, then Distributions on those
Preferred Securities will continue to accumulate at the then applicable rate,
from the date of redemption to the date of actual payment. In this case, the
actual payment date will be the date fixed for redemption for purposes of
calculating the Redemption Price.
 
                                       29
<PAGE>   31
 
     Flagstar Bancorp or its affiliates may at any time and from time to time
purchase outstanding Preferred Securities, by tender, in the open market or by
private agreement, and may resell Preferred Securities.
 
     If Flagstar Trust is going to redeem less than all the Preferred Securities
and Common Securities, then the aggregate liquidation amount of Preferred and
Common Securities to be redeemed will be allocated approximately 3% to the
Common Securities and 97% to the Preferred Securities, except if an Event of
Default has occurred. In such case, holders of Preferred Securities will be paid
first. See "-- Subordination of the Common Securities" immediately below for a
more complete discussion. The Property Trustee will select the particular
Preferred Securities to be redeemed on this pro rata basis not more than 60 days
before the date of redemption by any method the Property Trustee deems fair and
appropriate, or if the Preferred Securities are then held in book-entry form, in
accordance with DTC's customary procedures.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of Distributions on, and the Redemption Price of, the Preferred
Securities and Common Securities will be made on a proportionate basis, based on
the aggregate Liquidation Amounts of the Preferred Securities and Common
Securities. However, if a Debenture Event of Default has occurred and is
continuing, then no payment of any Distribution will be made on any of the
Common Securities, unless all unpaid amounts due on the Preferred Securities
shall have been paid in full or provided for, as appropriate.
 
     In the case of any Event of Default under the Trust Agreement resulting
from a Debenture Event of Default, we as the holder of the Common Securities
will be deemed to have waived any right to act upon the Event of Default under
the Trust Agreement until the effects of all Events of Default under the Trust
Agreement regarding the Preferred Securities have been cured, waived or
otherwise eliminated. Until that time, the Property Trustee shall act solely on
behalf of the holders of the Preferred Securities.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     We will have the right at any time to dissolve Flagstar Trust, and after
paying all the expenses and liabilities of Flagstar Trust, distribute the Junior
Subordinated Debentures to you. However, we may only dissolve Flagstar Trust if
we have received prior approval of federal banking regulators, if then required.
See "-- Distribution of Junior Subordinated Debentures" above.
 
     In addition, the Trust Agreement states that Flagstar Trust will dissolve:
 
     - on the expiration of the term of Flagstar Trust, which currently expires
       on             , 2029;
 
     - upon the bankruptcy of Flagstar Bancorp;
 
     - upon the filing of a certificate of dissolution or its equivalent of
       Flagstar Bancorp;
 
     - upon our delivery of a written direction to the Property Trustee to
       dissolve Flagstar Trust, which we may do in our discretion; or
 
     - upon entry of a court order for the dissolution of Flagstar Bancorp or
       Flagstar Trust.
 
     In the event of a dissolution, after Flagstar Trust pays all amounts owed
to its creditors, the holders of the Preferred Securities and Common Securities
issued by Flagstar Trust will be entitled to receive:
 
     - cash, if the dissolution arises from redemption of the Junior
       Subordinated Debentures, equal to the aggregate Liquidation Amount of
       each Preferred Security and Common
 
                                       30
<PAGE>   32
 
       Security specified in this Prospectus, plus accumulated and unpaid
       Distributions to the date of payment; or
 
     - Junior Subordinated Debentures, if the dissolution does not arise from
       redemption of the Junior Subordinated Debentures, in an aggregate
       principal amount equal to the aggregate Liquidation Amount of the
       Preferred Securities and Common Securities are distributed to the holders
       of the Preferred Securities and Common Securities.
 
     If Flagstar Trust cannot pay the full amount due on its Preferred
Securities and Common Securities because insufficient assets are available for
payment, then the amounts payable by Flagstar Trust on its Preferred Securities
and Common Securities shall be paid pro rata. However, if a Debenture Event of
Default has occurred, the total amounts due on such Preferred Securities will be
paid before any distribution on such Common Securities.
 
     Under current United States federal income tax law and interpretations and
assuming, as expected, Flagstar Trust is treated as a grantor trust, a
distribution of the Junior Subordinated Debentures should not be a taxable event
to you. 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 you. See "United States Federal Income Tax Consequences."
 
     If we elect to liquidate Flagstar Trust and cause the Junior Subordinated
Debentures to be distributed to you in liquidation of Flagstar Trust, we will
continue to have the right to shorten the maturity of the Junior Subordinated
Debentures, subject to certain conditions. See "Description of the Junior
Subordinated Debentures -- Option to Accelerate Maturity."
 
EVENTS OF DEFAULT; NOTICE
 
     The following events constitute an Event of Default (an "Event of Default")
with respect to the Preferred Securities and Common Securities:
 
          (i) the occurrence of a Debenture Event of Default under the Indenture
     (see "Description of Junior Subordinated Debentures -- Debenture Events of
     Default"); or
 
          (ii) default by Flagstar Trust in the payment of any Distribution when
     it becomes due and payable (other than during an Extension Period), and
     continuation of such default for a period of 30 days; or
 
          (iii) default by Flagstar Trust in the payment of any Redemption Price
     of any Trust Security when it becomes due and payable; or
 
          (iv) material default in the performance, or breach, of any covenant
     or warranty of the Property Trustee in the Trust Agreement (other than a
     default or breach in the performance of a covenant or warranty which is
     addressed in clause (ii) or (iii) above), and continuation of such default
     or breach, for a period of 60 days after there has been given, to the
     Property Trustee 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) if the Property Trustee becomes bankrupt or insolvent and we do
     not appoint a successor to the Property Trustee within 60 days of the event
     of bankruptcy or insolvency.
 
     The Property Trustee must give notice of any uncured or unwaived Event of
Default to you, to us and to the Administrative Trustees. This notice must be
given within five Business Days after the Property Trustee actually knows of the
Event of Default. Flagstar Bancorp and the Administrative Trustees are required
to file annual certificates with the Property Trustee declaring whether we and
they are in compliance with all the conditions and covenants applicable to us
and them under the Trust Agreement.
 
                                       31

     If a Debenture Event of Default has occurred and is continuing, the
Preferred Securities will have a preference over the Common Securities upon
dissolution of Flagstar Trust as described above. See "-- Liquidation
Distribution upon Dissolution." Upon a Debenture Event of Default, unless the
principal of all the Junior Subordinated Debentures has already become due and
payable, either the Property Trustee or the holders of not less than 25% in
aggregate principal amount of the Junior Subordinated Debentures then
outstanding may declare all of the Junior Subordinated Debentures to be due and
payable immediately by giving us written notice of that fact (and to the
Property Trustee, if notice is given by holders of the Junior Subordinated
Debentures). If the Property Trustee or the holders of the Junior Subordinated
Debentures fail to declare the principal of all of the Junior Subordinated
Debentures due and payable upon a Debenture Event of Default, the holders of at
least 25% in Liquidation Amount of the Preferred Securities then outstanding
will have the right to declare the Junior Subordinated Debentures immediately
due and payable. In either event, payment of principal and interest on the
Junior Subordinated Debentures will remain subordinated to the extent provided
in the Indenture. In addition, holders of the Preferred Securities have the
right in certain circumstances to bring a Direct Action (as defined below). See
"Description of the Junior Subordinated Debentures -- Enforcement of Certain
Rights by Holders of Preferred Securities."
 
REMOVAL OF TRUSTEES
 
     As the holder of the Common Securities, we may at any time remove any
trustee, unless a Debenture Event of Default has occurred and is continuing. 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. Flagstar Bancorp as the
holder of the Common Securities has the sole power to remove the Administrative
Trustee. The resignation or removal of any Trustee and the appointment of a
successor Trustee is effective only on the acceptance of appointment by the
successor trustee in accordance with the provisions of the Trust Agreement.
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
 
     Unless an Event of Default has occurred and is continuing, we have the
right to appoint co-trustees or a separate Property Trustee. We may appoint
these additional trustees in order to meet the requirements of the Trust
Indenture Act or the state laws of any jurisdiction where property of Flagstar
Trust may be located. Our appointment of any additional trustees will be subject
to provisions of the Trust Agreement. In case a Debenture Event of Default has
occurred and is continuing, the Property Trustee alone will have power to make
such appointment.
 
MERGER OR CONSOLIDATION OF TRUSTEES
 
     Any Person (as defined in the Trust Agreement) 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 will 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 the Trust Agreement, provided such corporation shall be otherwise
qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF FLAGSTAR TRUST
 
     Flagstar Trust may, at our request, with the consent of the Administrative
Trustees and without your consent, consolidate, amalgamate, merge with or into
or be replaced by or convey,
 
                                       32
<PAGE>   34
 
transfer or lease its properties and assets substantially as an entirety to
another trust organized under the laws of any state provided that:
 
     - such successor entity either (a) expressly assumes all of the obligations
       of Flagstar 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 for distributions and payments upon liquidation,
       redemption and otherwise;
 
     - Flagstar Bancorp expressly appoints a trustee of such successor entity
       possessing the same powers and duties as the Property Trustee as the
       holder of the Junior Subordinated Debentures;
 
     - any such transaction does not adversely affect the rights, preferences
       and privileges of the holders of the Preferred Securities (including any
       Successor Securities) in any material respect;
 
     - such successor entity has a purpose substantially identical to that of
       Flagstar Trust;
 
     - the Successor Securities will be listed or traded on any national
       securities exchange or other organization on which the Preferred
       Securities may then be listed;
 
     - prior to such a transaction, Flagstar Bancorp has received an opinion
       from independent counsel to Flagstar Trust experienced in such matters to
       the effect that (a) such transaction 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 any such transaction, neither Flagstar Trust nor such
       successor entity will be required to register as an investment company
       under the Investment Company Act; and
 
     - Flagstar Bancorp or any permitted successor or designee 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 and enters into an agreement
       substantially similar to the Expense Agreement.
 
     In addition, unless all of the holders of the Preferred Securities and
Common Securities agree, Flagstar Trust may not consolidate, amalgamate, merge
with or into, or be replaced by any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it, if that transaction
would cause Flagstar Trust or the successor entity to be classified as other
than a grantor trust for United States federal income tax purposes.
 
VOTING RIGHTS; AMENDMENT OF THE 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 Flagstar Bancorp,
the Property Trustee and the Administrative Trustees, without the consent of the
holders of Trust Securities, (i) to cure any ambiguity, correct or supplement
any provisions in the 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 will be necessary to ensure
that Flagstar 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 Flagstar Trust will not be required to register as
an "investment company" under the Investment Company Act.
 
                                       33
<PAGE>   35
 
     We and the Trustees may amend the Trust Agreement (i) with the consent of
holders representing not less than a majority of the aggregate Liquidation
Amount of the outstanding Trust Securities, and (ii) upon receipt by both the
Property and Administrative Trustees of an opinion of counsel to the effect that
the amendment or the exercise of any power granted to trustees in accordance
with the amendment will not affect Flagstar Trust's status as a grantor trust
for United States federal income tax purposes or Flagstar Trust's exemption from
status as an "investment company" under the Investment Company Act.
 
     However, the Trust Agreement may not be amended without the consent of each
holder of Trust Securities to (i) change the amount or timing of any
Distribution on Trust Securities or otherwise adversely affect the amount of any
Distribution required to be made in respect of 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 Junior 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 Indenture Trustee, or
executing any trust or power conferred on the Property Trustee with respect to
the Junior Subordinated Debentures, (ii) waive any past default that is waivable
under the Indenture, (iii) exercise any right to rescind or annul a declaration
that the principal of all the Junior Subordinated Debentures shall be due and
payable or (iv) consent to any amendment, modification or termination of the
Indenture or the Junior 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 or in some cases, the prior consent of each holder of the Preferred
Securities.
 
     The Trustees may 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 will notify each holder of the Preferred Securities of
any notice of default with respect to the Junior Subordinated Debentures.
 
     In addition to obtaining these approvals, the Trustees must also obtain an
opinion of counsel experienced in such matters to the effect that Flagstar Trust
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 the 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 the 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 the Preferred Securities in the manner
set forth in the Trust Agreement.
 
     If we or any of our affiliates, or the Trustees or any of their affiliates
own any Preferred Securities, those Preferred Securities will not be treated as
outstanding for purposes of the votes or consents described above.
 
BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
 
     DTC will act as securities depositary for the Preferred Securities.
Flagstar Trust will issue one or more fully registered global Preferred
Securities certificates in the name of Cede & Co. (DTC's nominee). These
certificates will represent the total aggregate number of Preferred Securities.
Flagstar Trust will deposit these certificates with DTC or a custodian appointed
by DTC. Flagstar Trust will not issue certificates to you for the Preferred
Securities that you purchase, unless DTC's services are discontinued.
 
                                       34
<PAGE>   36
 
     DTC has provided Flagstar Trust and Flagstar Bancorp with the following
information: DTC 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, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered under the provisions of Section 17A of the Securities Exchange Act of
1934. DTC holds securities that its participants deposit with DTC. DTC 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 other organizations ("Direct Participants").
 
     DTC 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 DTC system is also
available to others, such as securities brokers and dealers, banks and trust
companies, that clear transactions through or maintain a direct or indirect
custodial relationship with a Direct Participant ("Indirect Participants"). The
rules applicable to DTC and its participants are on file with the SEC.
 
     When you purchase Preferred Securities within the DTC system, the purchase
must be made by or through a Direct Participant. The Direct Participant will
receive a credit for the Preferred Securities on DTC's records. You, as the
actual owner of the Preferred Securities, are the "beneficial owner." Your
beneficial ownership interest will be recorded on the Direct and Indirect
Participants' records, but DTC will have no knowledge of your individual
ownership. DTC's records reflect only the identity of the Direct Participants to
whose accounts Preferred Securities are credited.
 
     You will not receive written confirmation from DTC of your purchases. The
Direct or Indirect Participant through whom you purchased the Preferred
Securities should send you written confirmations providing details of your
transactions, as well as periodic statements of your holdings. The participants
are responsible for keeping accurate account of the holdings of their customers
like you.
 
     Transfers of ownership interests in the Preferred Securities will be
accomplished by entries made on the books of participants acting on behalf of
beneficial owners.
 
     The laws of some states may require that specified purchasers of securities
take physical delivery of the securities in definitive form. These laws may
impair the ability to transfer beneficial interests in the global certificate
representing the Preferred Securities.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants and by Direct
Participants and Indirect Participants to beneficial owners will be governed by
arrangements among them, and any statutory or regulatory requirements that may
be in effect from time to time.
 
     Redemption notices will be sent to Cede & Co. If less than all of the
Preferred Securities are being redeemed, DTC will reduce each Direct
Participant's holdings of Preferred Securities in accordance with its
procedures.
 
     In those cases where a vote by the holders of the Preferred Securities is
required, neither DTC nor Cede & Co. will itself consent or vote. Under its
usual procedures, DTC would mail an omnibus proxy to Flagstar Trust 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 the
Preferred Securities are credited on the record date, which are identified in a
listing attached to the omnibus proxy.
 
                                       35
<PAGE>   37
 
     Flagstar Trust will make distribution payments on the Preferred Securities
directly to DTC. DTC's practice is to credit Direct Participants' accounts on
the relevant payment date in accordance with their respective holdings shown on
DTC's records, unless DTC has reason to believe that it will not receive payment
on such payment date.
 
     Payments by participants (whether Direct Participants or Indirect
Participants) to beneficial owners will be governed by standing instructions and
customary practices, as is the case with securities held for the account of
customers in bearer form or registered in "street name." These payments will be
the responsibility of the participant and not of DTC, Flagstar Trust or Flagstar
Bancorp.
 
     Except as provided below in "Description of the Junior Subordinated
Debentures -- Discontinuance of the Depositary's Services," a beneficial owner
in a global Preferred Securities certificate will not be entitled to receive
physical delivery of Preferred Securities. Accordingly, each beneficial owner
must rely on the procedures of DTC to exercise any rights under the Preferred
Securities.
 
     DTC may discontinue providing its services as securities depositary with
respect to the Preferred Securities at any time by giving reasonable notice to
Flagstar Trust. In the event that a successor securities depositary is not
obtained, Flagstar Trust will print and deliver Preferred Securities
certificates. Additionally, the Administrative Trustees, with our consent, may
decide to discontinue the book-entry only system of transfers with respect to
the Preferred Securities. In that event, Flagstar Trust will print and deliver
certificates for the Preferred Securities to its holders.
 
     We have obtained the information in this section concerning DTC and DTC's
book-entry system from sources that we and Flagstar Trust believe to be
reliable, but neither we nor they take responsibility for the accuracy of the
information.
 
CERTIFICATED SECURITIES
 
     If the Preferred Securities do not remain in book-entry only form as
described above, the following provisions would apply:
 
     - The Property Trustee will act as paying agent and may designate an
       additional or substitute paying agent at any time.
 
     - Registration of transfers of Preferred Securities will be effected
       without charge by or on behalf of Flagstar Trust, but the registration
       will require payment, with the giving of such indemnity as Flagstar Trust
       or Flagstar Bancorp may require, for any tax or other governmental
       charges that may be imposed.
 
     - Flagstar Trust will not be required to register or cause to be registered
       the transfer of Preferred Securities after they 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 those 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 the Property Trustee is offered
reasonable indemnity against the costs, expenses and liabilities that it might
incur. 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 Trust Agreement or is unsure of the application of
any provision of the Trust
                                       36
<PAGE>   38
 
Agreement, and the matter is not one on which holders of the Preferred
Securities are entitled under the Trust Agreement to vote, then the Property
Trustee shall take such action as is directed by us. If we do not direct any
action, then the Property Trustee shall take such action as it deems advisable
and in the best interests of the holders of 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 operate Flagstar
Trust in such a way so that Flagstar Trust will not be:
 
     - required to register as an "investment company" under the Investment
       Company Act; or
 
     - characterized as other than a grantor trust for United States federal
       income tax purposes.
 
     We are authorized and directed to conduct our affairs so that the Junior
Subordinated Debentures will be treated as indebtedness for United States
federal income tax purposes on our books and accounts.
 
     We and the Administrative Trustees are authorized to take any action, not
inconsistent with applicable law, the certificate of trust of Flagstar Trust or
our articles of incorporation, that either we or the Administrative Trustees
determine in either of our discretion to be necessary or desirable to achieve
that end, as long as the action does not adversely affect the interests of the
holders of the Preferred Securities.
 
     Flagstar Trust may not borrow money, issue debt or mortgage or pledge any
of its assets.
 
               DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES
 
     The Junior Subordinated Debentures will be issued under the Subordinated
Indenture, dated as of April   , 1999 (the "Indenture"), between us and FMB
Bank, as the Indenture Trustee. The following summary of the terms and
provisions of the Junior 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. You should also read the Indenture for the complete
terms of the Junior Subordinated Debentures. The Indenture has been filed as an
exhibit to the Registration Statement. This Prospectus forms a part of the
Registration Statement. The Indenture is also qualified in its entirety by
reference to the Trust Indenture Act. The Indenture is qualified under the Trust
Indenture Act. We believe that this section of the Prospectus describes the
material terms of the Junior Subordinated Debentures and the Related Indenture.
 
     Flagstar Trust will invest the proceeds of the issuance of the Preferred
Securities and Common Securities in the Junior Subordinated Debentures that are
issued by us. Our Junior Subordinated Debentures are subordinated, unsecured
debt under the Indenture.
 
GENERAL
 
     We will issue the Junior Subordinated Debentures as unsecured debt under
the Indenture. The Junior Subordinated Debentures will be limited in aggregate
principal amount to the sum of the Liquidation Amount of the Preferred
Securities and the amount of capital that we contributed to Flagstar Trust in
exchange for the Common Securities.
 
     The Junior Subordinated Debentures contain no sinking fund provisions. The
entire principal amount of the Junior Subordinated Debentures will become due
and payable, together with any accrued and unpaid interest, including compound
interest and additional sums, if any, on                , 2029.
 
     If Junior Subordinated Debentures are distributed to holders of Preferred
Securities in liquidation of those holders' interests in Flagstar Trust, the
Junior Subordinated Debentures will
                                       37
<PAGE>   39
 
initially be issued as a global security. As described in "Description of the
Junior Subordinated Debentures -- Discontinuance of the Depositary's Services",
under limited circumstances, Junior Subordinated Debentures may be issued in
certificated form in exchange for a global security. See "-- Book-Entry and
Settlement; Depositary" below.
 
     If Junior Subordinated Debentures are issued in certificated form, we will
issue them in denominations of $25, and integral multiples of $25, and they may
be transferred or exchanged at the offices described below.
 
     We will make payments on Junior Subordinated Debentures issued as a global
security to DTC, a successor depositary or, if no depositary is used, to a
paying agent for the Junior Subordinated Debentures. If we issue Junior
Subordinated Debentures in certificated form, principal and interest will be
payable, the transfer of the Junior Subordinated Debentures will be registrable,
and Junior Subordinated Debentures will be exchangeable for Junior Subordinated
Debentures of other denominations of a like aggregate principal amount, at the
Corporate Trust Office of the Indenture Trustee in Baltimore, Maryland. At our
option, however, we may pay interest by check mailed to the address of the
persons entitled to the interest.
 
INTEREST
 
     The Junior Subordinated Debentures will bear interest at an annual rate of
     % from the original date of issuance until the principal becomes due and
payable. Interest is payable quarterly in arrears on the last Business Day of
March, June, September and December of each year, beginning June 30, 1999.
Interest payments not paid when due will accrue interest, compounded quarterly,
at the annual rate of      %.
 
     The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months, and, for any period shorter than a
quarter, on the basis of the actual number of days elapsed per 30-day month.
 
     The interest payment provisions for the Junior Subordinated Debentures
correspond to the distribution provisions for the Preferred Securities. See
"Description of the Preferred Securities -- Distributions".
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
     As long as we are not in default on the payment of interest on the Junior
Subordinated Debentures, we have the right, at any time and from time to time,
to defer payments of interest by extending the interest payment period for a
period not exceeding 20 consecutive quarters (an "Extension Period"), but not
beyond the maturity date of the Junior Subordinated Debentures. At the end of
any Extension Period, we will pay all interest then accrued and unpaid, together
with interest on that amount, compounded quarterly, at the annual rate of
     %. After termination of any Extension Period and the payment of all amounts
then due, we may begin a new Extension Period.
 
     During an Extension Period, interest will continue to accrue and holders of
Junior Subordinated Debentures will be required to accrue interest income for
United States federal income tax purposes. See "United States Federal Income Tax
Consequences."
 
     During any Extension Period:
 
     - we may not declare or pay any dividends on, make any distribution, or
       redeem, purchase, acquire or make a liquidation payment on any of our
       capital stock; and
 
     - we may not make any payment of interest, principal or premium on or
       repay, repurchase or redeem any debt securities issued by us that rank
       equal or junior to the Junior Subordinated Debentures, or make any
       guarantee payments on the foregoing.
 
                                       38
<PAGE>   40
 
     The Extension Period restrictions do not apply to:
 
     - repurchases, redemptions or other acquisitions of shares of our capital
       stock in connection with any employment contract, benefit plan or other
       similar arrangement with or for the benefit of any one or more employees,
       officers, directors or consultants, or a dividend reinvestment or
       shareholder stock purchase plan;
 
     - any declaration of a dividend in connection with any shareholders' rights
       plan, or the issuance of rights, stock or other property under any
       shareholders' rights plan, or the redemption or repurchase of rights
       pursuant to the plan;
 
     - any dividend in the form of stock, warrants, options or other rights
       where the dividend or the stock issuable upon exercise of the warrants,
       options or other rights is the same stock as that on which the dividend
       is being paid or ranks equal or junior to that stock; or
 
     - payments by us under the Guarantee.
 
     The restrictions described above will also apply if we default on our
obligations under the Junior Subordinated Debentures or the Guarantee.
 
     Before termination of any Extension Period, we may further extend the
interest payment period. However, the Extension Period, including all previous
and further extensions, may not exceed 20 consecutive quarters or extend beyond
the maturity date of the Junior Subordinated Debentures. After termination of
any Extension Period and the payment of all amounts then due, we may begin a new
Extension Period, for up to an additional 20 consecutive calendar quarters, as
described above.
 
     If the Property Trustee is the sole holder of the Junior Subordinated
Debentures, we will give the Administrative Trustees, the Indenture Trustee and
the Property Trustee notice of our selection of an Extension Period one business
day before the earlier of:
 
     - the next date Distributions on the Preferred Securities are payable; or
 
     - the date the Administrative Trustees are required to give notice to the
       holders of record of the Preferred Securities.
 
     The Indenture Trustee will give notice of our selection of an Extension
Period to the holders of the Preferred Securities. We may elect to begin an
Extension Period an unlimited number of times.
 
     If the Property Trustee is not the sole holder of the Junior Subordinated
Debentures, we will give the holders of the Junior Subordinated Debentures
notice of our selection of an Extension Period ten business days before the
earlier of:
 
     - the next interest payment date; or
 
     - the date upon which we are required to give notice to the New York Stock
       Exchange, or other applicable self-regulatory organization, or to holders
       of the Junior Subordinated Debentures of the record or payment date of
       the related interest payment.
 
     We have no present intention of exercising our right to defer payments of
interest by extending the interest payment period on the Junior Subordinated
Debentures.
 
ADDITIONAL SUMS
 
     If Flagstar Trust is required to pay any additional taxes, duties or other
governmental charges as a result of a Tax Event, we will pay as additional
amounts on the Junior Subordinated Debentures the amounts (i.e., the "Additional
Sums") required to be paid so that the Distributions paid by Flagstar Trust
shall not be reduced as a result of such charges.

REDEMPTION
 
     We have the right, after receipt of prior approval of the federal banking
regulators, if approval is then required, to redeem the Junior Subordinated
Debentures:
 
          (i) on or after             , 2004, 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, an Investment Company Event or a Capital Treatment Event.
 
     In either case, the Redemption Price will equal 100% of the principal
amount to be redeemed, plus any accrued and unpaid interest, to the date of
redemption.
 
     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 Junior Subordinated
Debentures to be redeemed at such holder's registered address. Interest will
cease to accrue on any Junior Subordinated Debentures that we call for
redemption, unless we default in payment of the Redemption Price.
 
     The Junior Subordinated Debentures will not be subject to any sinking fund.
 
OPTION TO ACCELERATE MATURITY DATE
 
     The Junior Subordinated Debentures will mature on             , 2029. We
may, at our option, shorten the maturity to any date not earlier than
            , 2004. We may only shorten the maturity date if we receive prior
approval from the federal banking regulators, if then required. We may only
elect to shorten the maturity once.
 
     If we elect to shorten the maturity, we will give notice to each registered
holder of the Junior Subordinated Debentures, the Property Trustee and the
Indenture Trustee within 90 days of the effective date of the shortened
maturity. The Property Trustee must give notice to the holders of Trust
Securities of the new maturity date of the Junior Subordinated Debentures. You
may be subject to adverse United States federal income tax consequences if we
shorten the maturity. See "United States Federal Income Tax Consequences --
Exercise of Right to Shorten Maturity."
 
DISTRIBUTION UPON LIQUIDATION
 
     As described under "Description of the Preferred Securities -- Liquidation
Distribution upon Dissolution," under certain circumstances involving the
dissolution of Flagstar Trust, the Junior Subordinated Debentures may be
distributed to the holders of the Preferred Securities and Common Securities in
liquidation of Flagstar Trust after the expenses of Flagstar Trust have been
paid in full. If distributed to holders of the Preferred Securities in
liquidation, the Junior 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 Junior
Subordinated Debentures. We anticipate that the depositary arrangements for the
Junior Subordinated Debentures will be substantially identical to those in
effect for the Preferred Securities. See "Book-Entry Issuance".
 
     If the Junior Subordinated Debentures are distributed to the holders of
Preferred Securities upon the liquidation of Flagstar Trust, there can be no
assurance as to the market price of the Junior Subordinated Debentures.
 
SUBORDINATION
 
     The Indenture provides that the Junior Subordinated Debentures rank junior
in right of payment to all of our "Senior and Subordinated Debt," defined below.
We may not make payment
 
                                       40
<PAGE>   42
 
of principal, including redemption payments, or interest on the Junior
Subordinated Debentures if
 
     - any of our Senior and Subordinated Debt is not paid when due and any
       applicable grace period after the default has ended and the default has
       not been cured or waived; or
 
     - the maturity of any of our Senior and Subordinated Debt has been
       accelerated because of a default, and the acceleration has not been
       rescinded.
 
     Upon any distribution of our assets to creditors upon our dissolution,
winding-up, liquidation or reorganization, whether voluntary or involuntary, or
in bankruptcy, insolvency, receivership or other proceedings, all principal,
premium, if any, and interest due or to become due on all of our Senior and
Subordinated Debt must be paid in full before the holders of Junior Subordinated
Debentures are entitled to receive or retain any payment. In that event, any
payment or distribution on the Junior Subordinated Debentures that would
otherwise be payable in respect of the Junior Subordinated Debentures, but for
the subordination provision, will be paid or delivered directly to the holders
of our Senior and Subordinated Debt in accordance with the priorities then
existing among the holders of our Senior and Subordinated Debt until all of our
Senior and Subordinated Debt has been paid in full.
 
     If the Indenture Trustee or any holder of Junior Subordinated Debentures
receives any payment or distribution on account of the Junior Subordinated
Debentures before all of our Senior and Subordinated Debt is paid in full, then
that payment or distribution will be paid to the holders of our Senior and
Subordinated Debt at the time outstanding.
 
     The rights of the holders of the Junior Subordinated Debentures will be
subrogated to the rights of the holders of our Senior and Subordinated Debt to
the extent of any payment we made to the holders of our Senior and Subordinated
Debt that otherwise would have been made to the holders of the Junior
Subordinated Debentures but for the subordination provisions.
 
SELECTED DEFINITIONS
 
     "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:
 
     - every obligation of such person for money borrowed or money owed;
 
     - every reimbursement obligation of such person with respect to letters of
       credit, bankers' acceptances or similar facilities;
 
     - 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);
 
     - every capital lease obligation of such person; and
 
     - every obligation of the type referred to in the foregoing clauses 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.
 
     "Senior and 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 Flagstar Bancorp
whether or not such claim for post-petition interest is allowed in such
proceeding), on Debt, whether incurred on, prior to or after the date of the
Indenture, unless, in the instrument creating or evidencing the Debt, it is
provided that such obligations are not superior in right of payment to the
Junior Subordinated Debentures or to
 
                                       41
<PAGE>   43
 
other Debt which ranks equal with, or subordinated to, the Junior Subordinated
Debentures. However, that Senior and Subordinated Debt will not include:
 
     - 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;
 
     - any Debt of the Company to any of its subsidiaries;
 
     - any Debt to any employee of the Company;
 
     - any Debt which by its terms is subordinated to trade accounts payable or
       accrued liabilities arising in the ordinary course of business but only
       to the extent that payments made to the holders of such Debt by the
       holders of the Junior 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;
 
     - the Guarantee; and
 
     - any other debt securities issued pursuant to the Indenture.
 
     The Indenture does not limit the amount of additional Senior and
Subordinated Debt that we may incur. We expect that from time to time we may
incur additional indebtedness constituting Senior and Subordinated Debt.
 
BOOK-ENTRY AND SETTLEMENT; DEPOSITARY
 
     If we distribute the Junior Subordinated Debentures to holders of Preferred
Securities in connection with the involuntary or voluntary dissolution,
winding-up or liquidation of Flagstar Trust, they will be issued in the form of
one or more global certificates registered in the name of a depositary or its
nominee. Except under the limited circumstances described immediately below
under "-- Discontinuance of the Depositary's Services," Junior Subordinated
Debentures represented by a global security will not be exchangeable for, and
will not otherwise be issuable as, certificated securities.
 
     If Junior Subordinated Debentures are distributed to holders of Preferred
Securities upon termination of Flagstar Trust, DTC will act as securities
depositary for the Junior Subordinated Debentures. For a description of DTC and
the specific terms of the depositary arrangements, see "Description of the
Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company."
 
     As of the date of this Prospectus, that description of DTC's book-entry
system and DTC's practices as they relate to purchases of, transfers of, notices
concerning and payments on the Preferred Securities apply in all material
respects to any debt obligations represented by one or more global securities
held by DTC.
 
     We may appoint a successor to DTC or any successor depositary if the
current depositary is unable or unwilling to continue as a depositary for the
global securities.
 
DISCONTINUANCE OF THE DEPOSITARY'S SERVICES
 
     A global security will be exchangeable for Junior Subordinated Debentures
registered in the names of persons other than the depositary or its nominee only
if:
 
     - the depositary notifies us that it is unwilling or unable to continue as
       a depositary for the global security and no successor depositary has been
       appointed;
 
                                       42
<PAGE>   44
 
     - the depositary ceases to be a clearing agency registered under the
       Exchange Act at a time the depositary is required to be so registered to
       act as depositary, and no successor depositary has been appointed;
 
     - we, in our sole discretion, determine that the global security shall be
       exchangeable for definitive certificates; or
 
     - there shall have occurred a Debenture Event of Default.
 
     Any global security that is exchangeable as described above will be
exchangeable for Junior Subordinated Debentures registered in the names the
depositary directs. We expect that the instructions will be based upon
directions received by the depositary from its participants with respect to
ownership of beneficial interests in the global security.
 
PAYMENT AND PAYING AGENTS
 
     Payment of principal and interest on the Junior Subordinated Debentures
will be made at the office of the Indenture Trustee. In addition, at our option,
we may pay interest by check mailed to the address of the holder of the
Preferred Security as it appears in the securities register or by transfer to an
account of the holder of the Preferred Security pursuant to proper transfer
instructions that we have received prior to the regular record date. However, we
may not exercise these options if the Junior Subordinated Debentures are
represented by a Global Subordinated Debenture. Payment of any interest on
Junior Subordinated Debentures will be made to the person in whose name such
Junior Subordinated Debenture is registered at the close of business on the
regular record date for such interest. We may at any time designate additional
Paying Agents or rescind the designation of any Paying Agent; however, we will
at all times be required to maintain a Paying Agent in each place of payment for
the Junior Subordinated Debentures.
 
     Any moneys deposited with the Indenture Trustee or any Paying Agent, or
held by us in trust, for the payment of the principal of or interest on the
Junior Subordinated Debentures and remaining unclaimed for two years after such
principal or interest has become due and payable shall, at our request, be
repaid to us. Thereafter the holder of our Junior Subordinated Debenture shall
look only to us for payment as one of our general unsecured creditors.
 
MODIFICATION OF INDENTURE
 
     The Indenture provides that we and the Indenture Trustee may enter into
supplemental indentures without the consent of the holders of Preferred
Securities to: (i) secure any securities, (ii) evidence the assumption by a
successor corporation of our obligations, (iii) add covenants for the protection
of the holders of Junior Subordinated Debentures, (iv) cure any ambiguity or
correct any inconsistency in the Indenture, (v) qualify or maintain the
qualification of the Indenture under Trust Indenture Act and (vi) evidence and
provide for the acceptance of appointment by a successor trustee.
 
     The Indenture also provides that we and the Indenture Trustee may, with the
consent of at least a majority of the holders in aggregate principal amount of
the Junior Subordinated Debentures then outstanding and affected, add any
provisions to or change the provisions of the Indenture or the rights of the
holders of the Junior Subordinated Debentures. We and the Indenture Trustee may
not, however, without the consent of each holder of the Junior Subordinated
Debentures:
 
     - extend the final maturity of the Junior Subordinated Debentures;
 
     - reduce the principal amount or premium, if any;
 
     - reduce the rate or extend the time of payment of interest;
 
                                       43
<PAGE>   45
 
     - reduce any amount payable on redemption; or
 
     - reduce the percentage of holders of the Junior Subordinated Debentures
       whose consent is required for any modification of the Indenture.
 
DEBENTURE EVENTS OF DEFAULT
 
     The Indenture provides that any one or more of the following described
events with respect to the Junior Subordinated Debentures that has occurred and
is continuing constitutes a "Debenture Event of Default" with respect to the
Junior Subordinated Debentures:
 
     - failure for 30 days to pay any interest on the Junior Subordinated
       Debentures, when due (not including the deferral of any due date in the
       case of an Extension Period); or
 
     - failure to pay any principal on the Junior Subordinated Debentures when
       due whether at maturity, upon redemption by declaration or otherwise; or
 
     - our failure to observe or perform in any material respect certain other
       covenants contained in the Indenture for 90 days after written notice to
       us from the Indenture Trustee or to us and the Indenture Trustee by the
       holders of at least 25% in aggregate outstanding principal amount of the
       Junior Subordinated Debentures; or
 
     - certain events in bankruptcy, insolvency or reorganization of Flagstar
       Bancorp, including the voluntary commencement of bankruptcy proceedings,
       entry of an order for relief against us in a bankruptcy proceeding,
       appointment of a custodian over substantially all of our property, a
       general assignment for the benefit of creditors, or a court order for our
       liquidation; or
 
     - if Flagstar Trust shall have voluntarily or involuntarily dissolved,
       wound up its business or otherwise terminated its existence (except in
       connection with (i) the distribution of Junior Subordinated Debentures to
       the holders in liquidation of their interests in Flagstar Trust; (ii) the
       redemption of all of the outstanding Trust Securities; or (iii) certain
       mergers, consolidations or amalgamations, each as permitted by the Trust
       Agreement).
 
     The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debentures have the right to direct any proceeding for any
remedy available to the Indenture Trustee. The Indenture Trustee or the holders
of not less than 25% in aggregate outstanding principal amount of the Junior
Subordinated Debentures may declare the principal due and payable immediately
upon a Debenture Event of Default.
 
     However, the holders of a majority in aggregate outstanding principal
amount of the Junior Subordinated Debentures may annul such declaration and
waive the default if the default (other than the non-payment of the principal of
the Junior 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 Indenture Trustee. If the holders of the Junior
Subordinated Debentures fail to annul such declaration and waive such default,
the holders of a majority in aggregate Liquidation Amount of the Preferred
Securities would have such right.
 
     In case a Debenture Event of Default occurs, the Property Trustee may
declare the principal of and the interest on the Junior Subordinated Debentures,
and any other amounts payable under the Indenture, to be due and payable and to
enforce its other rights as a creditor with respect to the Junior Subordinated
Debentures.
 
     We will be required to file annually with the Indenture Trustee a
certificate, signed by one of our officers, stating whether or not such officer
knows of any default by us in the performance, observance or fulfillment of any
condition or covenant of the Indenture.
 
                                       44
<PAGE>   46
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
     If a Debenture Event of Default for failure to pay interest or principal on
the Junior Subordinate Debentures has occurred and is continuing, you may
institute a legal proceeding directly against us for enforcement of payment to
you of the principal of or interest on the Junior Subordinated Debentures in an
amount equal to the aggregate Liquidation Amount of the Preferred Securities you
hold ("Direct Action"). Our failure to pay principal or interest during an
Extension Period is not a Debenture Event of Default. If the right to bring a
Direct Action is removed, Flagstar Trust may become subject to the reporting
obligations under the Exchange Act. We have the right under the Indenture to
set-off any payment made to a holder of Preferred Securities by us in connection
with a Direct Action.
 
     Unless an Event of Default under the Trust Agreement has occurred, you will
not be able to exercise directly any remedies except for those listed above. See
"Description of the Preferred Securities -- Events of Default; Notice."
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
     The Indenture provides that the Company shall not consolidate with, convert
into 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, convert into or merge into the Company or convey, transfer or
lease its properties and assets substantially as an entirety to the Company.
 
     However, this does not apply if (i) in case the Company consolidates with,
converts into 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 Person expressly assumes the Company's
obligations on the Junior 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.
 
     If these conditions are met, the holders of the Preferred Securities have
no grounds to object to a highly leveraged or other transaction involving the
Company even if it may adversely affect holders of the Junior Subordinated
Debentures.
 
SATISFACTION AND DISCHARGE
 
     The Indenture provides that when, among other things, all Junior
Subordinated Debentures not previously delivered to the Indenture Trustee for
cancellation (i) have become due and payable or (ii) will become due and payable
at their maturity date within one year, and we deposit with the Indenture
Trustee, in trust, funds for the purpose and in an amount sufficient to pay and
discharge the entire indebtedness on the outstanding Junior Subordinated
Debentures, for the principal and interest to the date of the deposit or to the
stated maturity, as the case may be, then the Indenture will cease to be of
further effect. However, we will continue to be obliged to pay all other sums
due pursuant to the Indenture and to provide the officers' certificates and
opinions of counsel required by the Indenture. Under these conditions, we will
be deemed to have satisfied and discharged the Indenture.
 
GOVERNING LAW
 
     The Indenture and the Junior Subordinated Debentures will be governed by
and construed in accordance with the laws of the State of Delaware.
 
                                       45
<PAGE>   47
 
INFORMATION CONCERNING THE INDENTURE TRUSTEE
 
     The Indenture Trustee will be unaffiliated with us. For matters relating to
compliance with Trust Indenture Act, the Indenture Trustee will have all of the
duties and responsibilities of an Indenture Trustee under the Trust Indenture
Act. The Indenture Trustee, other than during the occurrence and continuance of
a Debenture Event of Default, undertakes to perform only such duties as are
specifically set forth in the Indenture and, upon a Debenture Event of Default,
must use the same degree of care and skill as a prudent person would use in the
conduct of his or her own affairs. Subject to this provision, the Indenture
Trustee is under no obligation to exercise any of the powers given it by the
Indenture at the request of any holder of Preferred Securities unless it is
offered reasonable security or indemnity against the costs, expenses and
liabilities that it might incur. However, the holders of the Preferred
Securities will not be required to offer such an indemnity where the holders, by
exercising their voting rights, direct the Indenture Trustee to take any action
following a Debenture Event of Default.
 
COVENANTS OF THE COMPANY
 
     We have made certain covenants in the Indenture. One specific covenant we
have agreed to is that we will pay to Flagstar Trust the Additional Sums so long
as Flagstar Trust holds the Junior Subordinated Debentures.
 
     In addition, we have also agreed to the following terms:
 
     - we will maintain directly or indirectly 100% ownership of the Common
       Securities. However, the Indenture does allow us to transfer ownership of
       the Common Securities to certain successors;
 
     - we will not voluntarily dissolve Flagstar Trust unless we have received
       prior approval from federal banking regulators, if required. However, we
       may voluntarily dissolve Flagstar Trust if we distribute the Junior
       Subordinated Debentures to holders of the Preferred Securities or if
       Flagstar Trust is a party to certain mergers, consolidations or
       amalgamations permitted by the Trust Agreement; and
 
     - we will use our reasonable best efforts to cause Flagstar Trust to be
       classified as a grantor trust and thus not be taxed 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, if there is a dissolution of Flagstar Trust, the Junior
Subordinated Debentures. The Preferred Securities and the Junior 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 Junior
Subordinated Debentures and will be deposited with the Depositary.
 
     The Depositary may discontinue providing its services as securities
depositary with respect to any of the Preferred Securities or the Junior
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 Securities or Subordinated Debenture
certificates representing such Preferred Securities or Junior Subordinated
Debentures are required to be printed and delivered. At our option, we 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 Amount of Preferred Securities or aggregate
principal amount of Junior Subordinated Debentures may determine to discontinue
the system of book-entry transfers through the Depositary. In any such event,
definitive
 
                                       46
<PAGE>   48
 
certificates for such Preferred Securities or Junior Subordinated Debentures
will be printed and delivered.
 
     The Depositary's management is aware that some computer applications,
systems, and the like for processing data ("Systems") that are dependent upon
calendar dates, including dates before, on, and after January 1, 2000, may
encounter "Year 2000 problems." The Depositary has informed its participants and
other members of the financial community (the "Industry") that it has developed
and is implementing a program so that its Systems, as the same relate to the
timely payment of distributions (including principal and income payments) to
security holders, book-entry deliveries and settlement of trades with the
Depositary, continue to function appropriately. This program includes a
technical assessment and a remediation plan, each of which is complete.
Additionally, the Depositary's plan includes a testing phase, which is expected
to be completed within appropriate time frames.
 
     However, the Depositary's ability to perform properly its services is also
dependent upon other parties, including but not limited to issuers and their
agents, as well as third-party vendors from whom the Depositary licenses
software and hardware, and third-party vendors on whom the Depositary relies for
information or the provision of services, including telecommunication and
electrical utility service providers, among others. The Depositary has informed
the Industry that it is contacting (and will continue to contact) third-party
vendors from whom the Depositary acquires services to: (i) impress upon them the
importance of such services being Year 2000 compliant and (ii) determine the
extent of their efforts for Year 2000 remediation (and, as appropriate, testing)
of their services. In addition, the Depositary is in the process of developing
such contingency plans as it deems appropriate.
 
     According to the Depositary, the foregoing information with respect to the
Depositary has been provided to the Industry for informational purposes only and
is not intended to serve as a representation, warranty or contract modification
of any kind.
 
                            DESCRIPTION OF GUARANTEE
 
     We will execute and deliver the Preferred Securities Guarantee Agreement
(the "Guarantee") concurrently with the issuance of the Preferred Securities for
the benefit of the holders of the Preferred Securities. FMB Bank will act as
trustee under the Guarantee (the "Guarantee Trustee") for the purposes of
compliance with the Trust Indenture Act, and the Guarantee will be qualified
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,
including the definitions of certain terms, and 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. You should also read the Guarantee. The
Guarantee Trustee will hold the Guarantee for the benefit of the holders of the
Preferred Securities.
 
GENERAL
 
     Pursuant to the Guarantee, we will agree to pay in full on a subordinated
basis, to the extent set forth in the Guarantee, 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 Flagstar Trust
may have or assert other than the defense of payment.
 
     The following payments on the Preferred Securities, if not fully paid by
Flagstar Trust (the "Guarantee Payments"), are covered by the Guarantee, without
duplication:
 
     - any accumulated and unpaid Distributions required to be paid on the
       Preferred Securities, if Flagstar Trust has funds available to make the
       payment;
 
                                       47
<PAGE>   49
 
     - the Redemption Price, if Flagstar Trust has funds available to make the
       payment, with respect to any Preferred Securities called for redemption;
       and
 
     - upon a voluntary or involuntary dissolution, winding up or liquidation of
       Flagstar Trust other than in connection with the distribution of the
       Junior Subordinated Debentures to holders of the Preferred Securities,
       the lesser of
 
        (1) the aggregate of the $25 Liquidation Amount and all accumulated and
            unpaid Distributions on the Preferred Securities to the date of
            payment if Flagstar Trust has funds available to make the payment;
            or
 
        (2) the amount of assets Flagstar Trust has remaining available for
            distribution to holders of Preferred Securities.
 
     Our obligations to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by us to the holders of the Preferred Securities
or by causing Flagstar Trust to pay the amounts to the holders.
 
     The Guarantee will be full and unconditional from the time of issuance.
However, the Guarantee will not apply to any payment of Distributions due if
Flagstar Trust lacks funds legally available for payment as a result of a
failure by us to make payments of interest or principal on the Junior
Subordinated Debentures.
 
     We are a holding company and we have the right to participate in any
distribution of assets of any of our subsidiaries if any of our subsidiaries are
liquidated or reorganized. However, our right to participate is subject to the
prior claim of the subsidiary's creditors. Accordingly, our obligations under
the Guarantee will be effectively subordinated to all existing and future
liabilities of our subsidiaries, and holders of Preferred Securities should look
only to our assets for payments.
 
     The Guarantee does not limit our incurrence or issuance of other secured or
unsecured debt. We may issue or incur Senior and Subordinated Debt in the
future. We expect that we will issue or incur Senior and Subordinated Debt in
the future.
 
     We have, through the Guarantee, the Trust Agreement, the Junior
Subordinated Debentures, the Indenture and the Expense Agreement, taken
together, guaranteed on a subordinated basis all of Flagstar Trust's obligations
under the Preferred Securities. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes the
guarantee. It is only the combined operation of these documents that has the
effect of providing our guarantee on a subordinated basis of all of Flagstar
Trust's obligations under the Preferred Securities. See "Relationship Among the
Preferred Securities, the Junior Subordinated Debentures and the Guarantee."
 
THE EXPENSE AGREEMENT
 
     We will enter into an agreement with Flagstar Trust as to the expenses and
liabilities of Flagstar Trust (the "Expense Agreement"). We will fully and
unconditionally guarantee to each person or entity to whom Flagstar Trust
becomes indebted or liable, the full payment of any costs, expenses or
liabilities of Flagstar Trust, other than obligations of Flagstar Trust to the
holders of the Preferred Securities or other similar interests in Flagstar
Trust.
 
STATUS OF THE GUARANTEE
 
     The Guarantee is unsecured and ranks subordinate and junior in right of
payment to all Senior and Subordinated Debt in the same manner as the Junior
Subordinated Debentures. As such, it is (1) subordinate and junior in right of
payment to all of our other liabilities, (2) equal to the most senior preferred
stock now or hereafter issued by us, and with any guarantee now or
 
                                       48
<PAGE>   50
 
hereafter issued by us in respect of any preferred stock of our affiliates, and
(3) senior to our Common Stock.
 
     The Guarantee will constitute a guarantee of payment and not of collection.
The guaranteed party may institute a legal proceeding directly against us 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 Preferred Securities. The Guarantee will not
be discharged except by payment of the Guarantee Payments in full to the extent
not paid by Flagstar Trust or upon distribution of the Junior Subordinated
Debentures to the holders of the Preferred Securities.
 
AMENDMENTS AND ASSIGNMENT
 
     Except with respect to any changes which do not materially adversely affect
the rights of holders of the 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 the
outstanding Preferred Securities. A description of the way to obtain any
approval is described under "Description of the Preferred Securities -- Voting
Rights; Amendment of the Trust Agreement." All Guarantees and agreements
contained in the Guarantee will bind our successors, assigns, receivers,
trustees and representatives and are for the benefit of the holders of the
Preferred Securities then outstanding.
 
EVENTS OF DEFAULT
 
     An event of default under the Guarantee will occur when we fail to perform
any of our payment or other obligations under the Guarantee. The holders of at
least a majority in aggregate Liquidation Amount of the Preferred Securities
have the right to direct any proceeding for any remedy available to the
Guarantee Trustee relating to the Guarantee or to direct the exercise of any
trust or power conferred upon the Guarantee Trustee under the Guarantee.
 
     If the Guarantee Trustee fails to enforce the Guarantee, you may, after
your written request to the Guarantee Trustee to enforce the Guarantee, sue us
directly to enforce the Guarantee Trustee's rights under the Guarantee without
first instituting a legal proceeding against Flagstar Trust, the Guarantee
Trustee, or any other person or entity.
 
     Notwithstanding the foregoing, if we have failed to make a Guarantee
Payment, you may directly institute a proceeding against us to enforce the
Guarantee.
 
     We are required to file annually with the Guarantee Trustee a certificate
as to our compliance with all the conditions and covenants under the Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, other than during the occurrence and continuance of
a default by us 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 the 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 the Preferred Securities unless it is offered reasonable indemnity
against the costs, expenses and liabilities that it might incur.
 
TERMINATION OF THE GUARANTEE
 
     The Guarantee will remain in effect as long as the Preferred Securities are
outstanding.
 
                                       49

GOVERNING LAW
 
     The Guarantee will be governed by and construed in accordance with the laws
of the State of Delaware.
 
            RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE JUNIOR
                   SUBORDINATED DEBENTURES AND THE GUARANTEE
 
GUARANTEE
 
     Payments of Distributions and other amounts due on the Preferred Securities
are guaranteed by us to the extent described under "Description of Guarantee."
Taken together, our obligations under the Junior Subordinated Debentures, the
Indenture, the Trust Agreement, the Expense Agreement and the Guarantee provide,
in the aggregate, a guarantee on a subordinated basis for payments of
Distributions and other amounts due on the Preferred Securities (but only to the
extent Flagstar Trust has funds available for the payment of such
Distributions). 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 our obligations under those documents that has
the effect of providing a guarantee on a subordinated basis of Flagstar Trust's
obligations under the Preferred Securities.
 
     To the extent that we do not make required payments on the Junior
Subordinated Debentures, Flagstar Trust will not pay Distributions or other
amounts due on the Preferred Securities. Neither the guarantee described above
nor the Guarantee covers payment of Distributions when Flagstar Trust does not
have sufficient funds to pay such Distributions. In those circumstances, your
remedy is to institute a legal proceeding directly against us to enforce the
payment of the Distributions to you. Our obligations under the guarantee and the
Guarantee are subordinate and junior in right of payment to all Senior and
Subordinated Debt.
 
SUFFICIENCY OF PAYMENTS
 
     As long as we make payments required by the Junior Subordinated Debentures
held by Flagstar Trust, there will be sufficient funds to cover Distributions
and other payments due on the Preferred Securities, primarily because:
 
     - the aggregate principal amount of the Junior Subordinated Debentures will
       exceed the aggregate Liquidation Amount of the Preferred Securities by
       the amount of the Common Securities;
 
     - the interest rate and interest and other payment dates on the Junior
       Subordinated Debentures will match the distribution rate and distribution
       and other payment dates for the Preferred Securities;
 
     - we will directly pay for all costs, expenses and liabilities of Flagstar
       Trust except Flagstar Trust's obligations to holders of Preferred
       Securities; and
 
     - the Trust Agreement further provides that Flagstar Trust will not engage
       in any activity that is not consistent with the limited purposes of
       Flagstar Trust.
 
     Notwithstanding anything to the contrary in the Indenture, we have the
right to set-off any payment we are required to make with and to the extent we
have made, or are concurrently making a payment under the Guarantee.
 
                                       50
<PAGE>   52
 
ENFORCEMENT RIGHTS OF HOLDERS OF THE PREFERRED SECURITIES UNDER THE GUARANTEE
 
     A holder of the Preferred Securities may institute a legal proceeding
directly against us to enforce its rights under the Guarantee without first
instituting a legal proceeding against the Guarantee Trustee, Flagstar Trust or
any other person or entity.
 
     A default or event of default under any Senior and Subordinated Debt would
not constitute a Debenture Event of Default. However, in the event of payment
defaults under, or acceleration of, Senior and Subordinated Debt, the
subordination provisions of the Indenture provide that no payments may be made
in respect of the Junior Subordinated Debentures until the Senior and
Subordinated Debt have been paid in full or any payment default has been cured
or waived. Our failure to make the required payments on Junior Subordinated
Debentures will constitute a Debenture Event of Default.
 
LIMITED PURPOSE OF FLAGSTAR TRUST
 
     The Preferred Securities evidence a beneficial interest in Flagstar Trust,
and it exists for the sole purpose of issuing Trust Securities and investing
those proceeds in the Junior Subordinated Debentures. A principal difference
between the rights of a holder of the Preferred Securities and a holder of a
Junior Subordinated Debenture is that a holder of a Junior Subordinated
Debenture is entitled to receive the principal amount of and interest accrued on
Junior Subordinated Debentures from us, while a holder of the Preferred
Securities is entitled to receive Distributions from Flagstar Trust (or from us
under the Guarantee) if and to the extent Flagstar Trust has funds available for
the payment of such Distributions.
 
RIGHTS UPON DISSOLUTION
 
     Upon any voluntary or involuntary dissolution, winding-up or liquidation of
Flagstar Trust involving the liquidation of the Junior Subordinated Debentures,
the holders of Preferred Securities will be entitled to receive, out of assets
held by Flagstar Trust, the liquidation distribution in cash. See "Description
of the Preferred Securities -- Liquidation Distribution upon Dissolution." Upon
our voluntary or involuntary liquidation or bankruptcy, the Property Trustee, as
holder of the Junior Subordinated Debentures, would be one of our subordinated
creditors, subordinated in right of payment to all Senior and Subordinated Debt
as set forth in the Indenture. However, the Property Trustee, and indirectly the
holders of the Preferred Securities are entitled to receive payment in full of
principal and interest, before any of our stockholders receive payments or
distributions. Since we are the guarantor under the Guarantee and have agreed to
pay for all costs, expenses and liabilities of Flagstar Trust (other than
Flagstar Trust's obligations to the holders of its Preferred Securities), the
positions of a holder of the Preferred Securities and a holder of Junior
Subordinated Debentures relative to other creditors and to our stockholders in
the event of our liquidation or bankruptcy are expected to be substantially the
same.
 
                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     This discussion summarizes the opinion of Kutak Rock, special tax counsel
to Flagstar Bancorp and Flagstar Trust ("Tax Counsel"), of the United States
federal income tax consequences of the purchase, ownership, and disposition of
the Preferred Securities that Tax Counsel anticipates to be material to
investors. Unless otherwise stated, this summary only deals with Preferred
Securities held as capital assets (generally, assets held for investment) by
holders who purchase the Preferred Securities upon original issuance. Your tax
treatment may vary depending on your particular situation.
 
                                       51
<PAGE>   53
 
     This summary does not address:
 
     - all of the tax consequences that may be relevant to holders who may be
       subject to special tax treatment such as, for example, financial
       institutions, insurance companies, broker-dealers, tax-exempt
       organizations or investors who have acquired Preferred Securities as part
       of a straddle, hedge or similar transaction or, except as described
       below, non-U.S. Holders, as we define that term below;
 
     - the tax consequences to holders that have a functional currency other
       than the United States dollar;
 
     - the tax consequences to shareholders, partners or beneficiaries of a
       holder of Preferred Securities;
 
     - any aspects of state, local or foreign tax laws; or
 
     - the United States federal alternative minimum tax consequences of the
       purchase, ownership and sale of Preferred Securities.
 
     Tax Counsel's opinion is based on the United States federal income tax law
in effect as of the date of this Prospectus. These laws may change, and any
change could have a retroactive effect. These laws are also subject to various
interpretations, and the IRS or the courts could later disagree with the
explanation of conclusions contained in this summary. The IRS has not formally
ruled (and we do not intend to seek a ruling) on the tax consequences of
purchasing, holding, and selling the Preferred Securities. Accordingly, the IRS
could challenge the opinions expressed in this Prospectus concerning such
consequences, and a court could agree with the IRS. We urge you to consult your
tax advisor as to the particular tax consequences to you of purchasing, owning,
and disposing of the Preferred Securities, including the application and effect
of United States federal, state, local, foreign and other tax laws.
 
     For purposes of this discussion, a "U.S. Holder" means:
 
     - a citizen or resident of the United States (or someone treated as a
       citizen or resident of the United States for federal income tax
       purposes);
 
     - a corporation, partnership, or other entity created or organized (or
       treated as created or organized for United States federal income tax
       purposes) in the United States or under the laws of the United States or
       of any political subdivision of the United States;
 
     - an estate, the income of which is includible in gross income for United
       States federal income tax purposes regardless of its source; or
 
     - a trust, the administration of which is subject to the primary
       supervision of a United States court and that has one or more United
       States persons who have the authority to control all substantial
       decisions of the trust.
 
CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES
 
     Based on the opinion of Tax Counsel, we will treat the Junior Subordinated
Debentures for United States federal income tax purposes as indebtedness of
Flagstar Bancorp. By accepting the Preferred Securities, you agree to treat the
Junior Subordinated Debentures as indebtedness for United States federal income
tax purposes and to treat the Preferred Securities as evidence of an indirect
beneficial ownership interest in the Junior Subordinated Debentures. No
assurance can be given, however, that such treatment will not be challenged by
the IRS or, if challenged, that such a challenge will not be successful.
 
                                       52
<PAGE>   54
 
CLASSIFICATION OF FLAGSTAR TRUST
 
     Tax Counsel is of the opinion that Flagstar Trust 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, you will
generally be treated as the owner of an undivided interest in the Junior
Subordinated Debentures. As further discussed below, you may be required to
include in ordinary income your allocable share of interest paid or accrued on
the Junior Subordinated Debentures.
 
POTENTIAL EXTENSION OF INTEREST PAYMENT PERIOD AND ORIGINAL ISSUE DISCOUNT
 
     We have the right to defer payments of interest on the Junior Subordinated
Debentures, which could cause the Junior Subordinated Debentures treated as
having been issued with OID. In general, a debt instrument will be deemed to
have been issued with OID for United States federal income tax purposes if there
is more than a remote contingency that periodic stated interest payments due on
the instrument will not be timely paid. Because the exercise by us of our option
to defer the payment of stated interest on the Junior Subordinated Debentures
would also prevent us from declaring dividends on any class of equity, we
believe that the likelihood that we would exercise the option is remote.
 
     As a result, we intend to take the position, based on the advice of Tax
Counsel, that the Junior Subordinated Debentures will not be deemed to be issued
with OID. Accordingly, based on this position, stated interest payments on the
Junior Subordinated Debentures will be includible in your ordinary income at the
time that those payments are paid or accrued in accordance with your regular
method of accounting and in the amount of each payment. Because these Treasury
Regulations have not yet been addressed in any revenue rulings or other
published interpretations issued by the IRS, it is possible that the IRS could
take a position contrary to the position taken by us.
 
EXERCISE OF DEFERRAL OPTION
 
     If we exercise our option to defer the payment of stated interest on the
Junior Subordinated Debentures, they would be treated, solely for purpose of the
OID rules, as being "re-issued" at that time with OID. Under these rules, you
would be required to include OID in ordinary income, on a current basis, over
the period that the instrument is held, even though we would not be making any
actual cash payments during the extended interest payment period.
 
     The amount of interest income treated as OID and therefore includible in
the taxable income of a holder of the Junior Subordinated Debentures would be
determined on the basis of a constant yield method over the remaining term of
the instrument, not on the basis of the stated interest amount. The actual
receipt of future payments of stated interest on the Junior Subordinated
Debentures would no longer be separately reported as taxable income because it
would have been replaced, solely for tax purposes, by the amount of OID. The
amount of OID that would accrue, in total, during the extended interest payment
period would be approximately equal to the amount of the cash payment due at the
end of the period. Any OID included in income would increase your adjusted tax
basis in the Preferred Securities or the Junior Subordinated Debentures,
depending on which you held at that time, and interest payments actually
received would reduce your adjusted tax basis.
 
     If the likelihood of the Company deciding to defer any payments of interest
were not treated as remote, the Junior Subordinated Debentures would be
considered as issued initially with OID in an amount equal to the sum of all the
interest payable over the term of the Junior Subordinated Debentures. Again,
this would mean that you would have to include interest income in gross income
for United States federal income tax purposes as it accrued daily on an economic
accrual basis instead of on the dates you actually received the cash payments.
 
                                       53
<PAGE>   55
 
     The IRS has not issued any rulings or interpretations which define the
meaning of the term "remote" as used in the applicable income tax regulations.
The IRS could take a position that differs from what we state in this
Prospectus.
 
CORPORATE U.S. HOLDERS
 
     Because the income from the Preferred Securities will not be considered to
be dividends for federal income tax purposes, corporate U.S. Holders of the
Preferred Securities will not be entitled to a dividends-received deduction for
any income received from the Preferred Securities.
 
RECEIPT OF JUNIOR SUBORDINATED DEBENTURES OR CASH UPON TERMINATION OF FLAGSTAR
TRUST
 
     If we exercise our right to terminate Flagstar Trust and cause the Junior
Subordinated Debentures to be distributed to you on a basis proportionate to
your ownership in the Preferred Securities, the distribution would be treated as
a nontaxable event to you. In that event, you would have an adjusted tax basis
in the Junior Subordinated Debentures that you receive equal to the adjusted tax
basis in the Preferred Securities that you surrender, and the holding period of
the Junior Subordinated Debentures would include the period during which you
held the Preferred Securities. If, however, Flagstar Trust is characterized for
United States federal income tax purposes as an association taxable as a
corporation at the time of the termination, the distribution of the Junior
Subordinated Debentures would be a taxable event to the holders of Preferred
Securities.
 
     If we redeem the Junior Subordinated Debentures for cash and Flagstar Trust
distributes the proceeds of the redemption to holders in redemption of their
Preferred Securities, the redemption would be treated as a sale of the Preferred
Securities in which you would recognize gain or loss as described immediately
below.
 
EXERCISE OF RIGHT TO SHORTEN MATURITY
 
     We have the right to shorten the maturity of the Junior Subordinated
Debentures. If we exercise our right to shorten the maturity of the Junior
Subordinated Debentures, this could result in a taxable event to you. Federal
income tax regulations provide that a significant modification of a debt
instrument is a taxable event. A significant modification includes shortening
the maturity of a debt instrument, provided that the instrument's rate of return
changes by more than the greater of 25 basis points or five percent of the
annual rate of return. At the present time, the extent to which the Junior
Subordinated Debenture's rate of return would change (if we exercised our right
to shorten the maturity) is unclear.
 
SALE OF PREFERRED SECURITIES
 
     Upon the sale of Preferred Securities (including a redemption for cash),
you will recognize gain or loss in an amount equal to the difference between the
amount realized (which for this purpose, will exclude amounts attributable to
accrued interest or OID not previously included in income, which amount will be
subject to tax as ordinary interest income) and your adjusted tax basis in the
Preferred Securities.
 
     If we do not defer interest payments on the Junior Subordinated Debentures,
your adjusted tax basis in the Preferred Securities generally will equal the
initial purchase price that you paid for the Preferred Securities. If, however,
we elect to defer interest payments on the Junior Subordinated Debentures, your
adjusted tax basis in the Preferred Securities will equal: (1) the initial
purchase price that you paid for the Preferred Securities; (2) increased by the
amount of any accrual and unpaid distributions you were required to treat as
OID; and (3) reduced by the amount of cash or other property received by you
with respect to such OID.
 
                                       54
<PAGE>   56
 
     The gain or loss will be capital gain or loss and will be long-term capital
gain or loss if you have held the Preferred Securities for more than one year.
Capital losses generally cannot be applied to offset ordinary income for United
States federal income tax purposes.
 
     The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest, or OID, if the Junior
Subordinated Debentures are treated as having been issued, or reissued, with
OID, relating to the underlying Junior Subordinated Debentures. If you dispose
of your Preferred Securities you will be required to include in your ordinary
income:
 
     - any portion of the amount realized that is attributable to accrued but
       unpaid interest to the extent not previously included in income; or
 
     - any amount of OID that has accrued on your proportionate share of the
       underlying Junior Subordinated Debentures during the taxable year of sale
       through the date of disposition.
 
     However, you can also increase your adjusted tax basis in the Preferred
Securities to the extent that you include these amounts in ordinary income.
 
WITHHOLDING OF U.S. TAXES ON NON-U.S. HOLDERS
 
     This summary assumes that the non-U.S. Holder
 
     - is an individual;
 
     - is not and will not become engaged in a United States trade or business;
       and
 
     - will not be present in the United States for 183 days or more during any
       particular taxable year.
 
     Payments made to a holder of Preferred Securities who is a non-U.S. Holder
generally will not be subject to withholding of United States federal income
tax, if:
 
     - the beneficial owner of the Preferred Securities does not actually or
       constructively own 10% or more of the total combined voting power of all
       classes of stock entitled to vote; and
 
     - either:
 
          (1) the beneficial owner of the Preferred Securities certifies to
              Flagstar Trust or its agent, under penalties of perjury, that it
              is not a United States person and provides his name and address;
              or
 
          (2) a securities clearing organization, bank or other financial
              institution that holds customers' securities in the ordinary
              course of its trade or business (a "Financial Institution"), and
              holds the capital securities in that capacity, certifies to
              Flagstar Trust or its agent, under penalties of perjury, that such
              statement has been received from the beneficial owner by it or by
              a Financial Institution between it and the beneficial owner and
              furnishes Flagstar Trust or its agent with a copy of the
              statement.
 
     In addition, a non-U.S. Holder of Preferred Securities will not be subject
to withholding of United States federal income tax on any gain realized upon the
sale or other disposition of a capital security.
 
BACKUP WITHHOLDING
 
     You may be subject to a "backup withholding" tax of 31% on distributions
made on the Preferred Securities and on the entire price received on the sale of
the Preferred Securities if you:
 
     - fail to provide your Social Security or taxpayer identification number to
       your broker;
 
     - provide your broker with an incorrect Social Security or tax
       identification number;
 
                                       55
<PAGE>   57
 
     - fail to provide your broker with a certified statement that your Social
       Security or tax identification number is correct and that you are not
       subject to backup withholding; or
 
     - improperly report interest and dividends on your tax return.
 
Backup withholding, however, does not apply to payments made to certain exempt
recipients such as corporations or tax-exempt organizations. Any withheld
amounts will be allowed as a credit against your United States federal income
tax, provided the required information is provided to the IRS.
 
                              ERISA CONSIDERATIONS
 
     Retirement plans are generally subject to the rules of the Employee
Retirement Income Security Act of 1974 ("ERISA"), and they are also subject to
requirements in the Code. Retirement plans may purchase Preferred Securities in
accordance with their governing documents. When they do, the fiduciaries for
these retirement plans (usually trustees and custodians) are required to comply
with fiduciary duties under ERISA and other requirements under the Code.
Retirement plans can be employer-sponsored plans like pension plans and profit
sharing plans, individual retirement accounts (IRAs), and other types of plans
which defer the receipt of income.
 
     If a retirement plan is sponsored and/or contributed to by a party that is
affiliated in certain ways with us, we and/or our affiliate could be a "party in
interest" or a "disqualified person" for purposes of ERISA and the Code. The
rules regarding these relationships are very complex. They can arise if we are a
fiduciary to a retirement plan, such as a trustee or custodian. They can arise
if we or one of our affiliates provides any services to or for the retirement
plan. Our affiliates are Flagstar Bank, Douglas Insurance Agency, Inc., FSSB
Real Estate Development Corporation, First Security Investment Group, Inc., FSSB
Mortgage Corporation, Flagstar Capital Corporation, Flagstar Credit Corporation,
Mid-Michigan Service Corporation and SSB Funding Corporation.
 
     There are many other circumstances which can cause the relationship to
exist. When one of these relationships exists, the purchase of Preferred
Securities by the retirement plan is likely to result in a transaction that is
not permitted by ERISA and/or the Internal Revenue Code. These transactions are
referred to as "prohibited transactions" or "disqualifying transactions." These
could lead to excise tax penalties and even tax disqualification of a retirement
plan. However, there may be ways to exempt prohibited transactions from the
excise tax penalties and tax disqualification. This may require application to a
governmental agency.
 
     If we or one of our affiliates is a party in interest or disqualified
person as to a retirement plan, that retirement plan should not acquire
Preferred Securities without first establishing an exemption. Entities like
partnerships and limited liability companies which have a relationship with us
and/or one of our affiliates and that may be holding assets of retirement plans
also have to address these prohibited transaction issues. All of these rules are
very complicated. If you have a relationship of any kind with us and/or one of
our affiliates, you should consult with your benefits counsel before acquiring
Preferred Securities.

                                  UNDERWRITING
 
     Upon the terms and subject to the conditions stated in the Underwriting

     The Underwriters are offering the Preferred Securities subject to their
acceptance of the securities from Flagstar Trust and subject to prior sale. The
Underwriting Agreement provides that the obligations of the Underwriters to pay
for and accept delivery of the Preferred Securities are conditioned on the
delivery of legal opinions by their counsel. The Underwriters are obligated to
purchase all the Preferred Securities if any are purchased.
 
     The Underwriters propose to offer part of the Preferred Securities directly
to the public at the public offering price set forth on the cover page of this
Prospectus and part of the Preferred Securities to certain dealers at a price
which represents a concession not in excess of $       per Preferred Security
under the public offering price. The Underwriters may allow, and such dealers
may reallow, a concession not in excess of $       per Preferred Security to
certain other dealers. After the initial offering of Preferred Securities to the
public, the public offering price and such concessions may be changed by the
Underwriters.
 
     Flagstar Trust has granted to the Underwriters an option, exercisable at
any time during the 30-day period from the date of this Prospectus, to purchase
up to an aggregate of 390,000 additional Preferred Securities at the public
offering price set forth on the cover page less underwriting discounts and
commissions. The Underwriters may exercise such option to purchase additional
Preferred Securities solely for the purpose of covering over-allotments, if any,
incurred in connection with the sale of the Preferred Securities offered by this
Prospectus. To the extent such option is exercised, each Underwriter will become
obligated, subject to certain conditions, to purchase a number of additional
Preferred Securities proportionate to such Underwriter's initial amount
reflected in the preceding table.
 
     Flagstar Bancorp, Flagstar Trust and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.

     The Underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation M
under the Exchange Act. Over-allotment involves syndicate sales in excess of the
offering size, which creates a syndicate short position. Stabilizing
transactions permit bids for and purchase of the Common Stock so long as the
stabilizing bids do not exceed a specified maximum. Syndicate covering
transactions involve purchases of the Preferred Securities in the open market in
order to cover syndicate short positions. Penalty bids permit the Underwriters
to reclaim a selling concession from a syndicate member when the Preferred
Securities originally sold by such syndicate member is purchased in a
stabilizing transaction or syndicate covering transaction to cover syndicate
short positions. Such stabilizing transactions, syndicate covering transactions
and penalty bids may cause the price of the Preferred Securities to be higher
than it would otherwise be in the absence of such transactions. These
transactions may be effected on The Nasdaq Stock Market(R) or otherwise and, if
commenced, may be discontinued at any time.
 
                                 TRANSFER AGENT
 
     Registrar and Transfer Company, Cranford, New Jersey, will act as registrar
and transfer agent for the Preferred Securities.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Flagstar's Restated Articles of Incorporation contain a provision,
authorized by the Michigan Business Corporation Act ("MBCA"), designed to
eliminate in certain circumstances the personal liability of directors for
monetary damages to Flagstar or its stockholders for breach of their fiduciary
duty as directors. This provision, however, does not limit the liability of any
director who breached his or her duty of loyalty to the Company or its
stockholders, failed to act in good faith, obtained an improper personal benefit
or paid a dividend or approved a stock repurchase or redemption that was
prohibited under Michigan law. This provision will not limit or eliminate the
rights of the Company or any stockholder to seek an injunction or any other
nonmonetary relief in the event of a breach of a director's duty of care. In
addition, this provision applies only to claims against a director arising out
of his or her role as a director and does not relieve a director from liability
unrelated to his fiduciary duty of care or from a violation of statutory law
such as certain liabilities imposed on a director under the federal securities
laws.
 
     The Company's Restated Articles of Incorporation and Restated Bylaws also
provide that the Company shall indemnify all directors and officers of the
Company to the full extent permitted by the MBCA. Under the provisions of the
MBCA, any director or officer who, in his or her capacity as such, is made or
threatened to be made a party to any suit or proceeding, may be indemnified if
the Board determines such director or officer 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 Company or its stockholders.
 
     Officers and directors are covered within specified monetary limits by
insurance against certain losses arising from claims made by reason of their
being directors or officers of the Company or of the Company's subsidiaries and
the Company's officers and directors are indemnified against such losses by
reason of their being or having been directors or officers of another
corporation, partnership, joint venture, trust or other enterprise at the
Company's or its subsidiaries' request.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes as follows:
 
          (a) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted form 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 Registrant 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.
 
          (b) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     Prospectus shall be deemed to be a new Registration Statement related 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.
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, when applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement 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 hereof.
 
                                      II-2
<PAGE>   63
 
     Insofar as indemnification for liabilities arising under the Securities Act
for 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

The Board of Directors
Flagstar Bancorp, Inc.
2600 Telegraph Road
Bloomfield Hills, MI 48302

ATTN.: MR. MICHAEL W. CARRIE

                                                          PRIVATE & CONFIDENTIAL
Ladies and Gentlemen:

         This letter of intent ("Letter of Intent") will confirm our recent
conversation and is intended to be an expression of our present mutual intent
concerning the potential initial public offering (the "Offering") of Cumulative
Preferred Securities (the "Preferred Securities") of Flagstar Trust ("Flagstar
Trust") a business trust to be formed as a wholly owned subsidiary of Flagstar
Bancorp, Inc. ("Bancorp") which is also the parent of Flagstar Bank, FSB
("Flagstar" or the "Bank"). Flagstar Trust would upon consummation of the
Offering, purchase a series of junior subordinated debentures from Bancorp for
the same denomination and with the same payment terms as the Preferred
Securities. We are pleased to advise you that, based on the information made
available to us, representations which you have made to us concerning the Bank
and Bancorp, their principals, their business and their prospects, and current
market conditions, Roney Capital Markets, a division of First Chicago Capital
Markets, Inc. ("Roney Capital Markets"), McDonald Investments Inc., Stifel,
Nicolaus & Company, Incorporated and JWGenesis Capital Markets, LLC
(collectively referred to as the "Managing Underwriters") hereby confirm in
principle their interest in underwriting on a firm commitment basis (subject to
the terms and conditions of the Underwriting Agreement) the Offering, the
general terms of which would be in accordance with the terms outlined below.

1.       PUBLIC OFFERING OF PREFERRED SECURITIES

The Managing Underwriters propose an offering as follows:

Issuer:                                       Flagstar Trust

Managing Underwriters:                        Roney Capital Markets (books)
                                              McDonald Investments Inc.
                                              Stifel, Nicolaus & Company,
                                              Incorporated
                                              JWGenesis Capital Markets, LLC

Security:                                     A  minimum   of   2,600,000  
                                              shares  of   Preferred Securities

Liquidation Preference:                       $25.00 per share

FLAGSTAR TRUST    
LETTER OF INTENT  
FEBRUARY 15, 1999 
PAGE 2 of 6




2.  CAPITALIZATION

         Flagstar Trust would have a minimum of 2,600,000 shares of Preferred
Securities outstanding immediately after the Offering, excluding the
over-allotment option. Flagstar Trust would also have outstanding Common Stock
owned by Bancorp which would represent an aggregate liquidation amount equal to
at least 3.00% of the total capital of Flagstar Trust, assuming no exercise of
the over-allotment option.


3.  OVER-ALLOTMENT OPTION  

         Flagstar Trust would grant the underwriters, for the purpose of
covering over-allotments, the right for a 30-day period after commencement of
the Offering to purchase from Flagstar Trust up to an additional 15% of the
shares of Preferred Securities offered at the public offering price less the
underwriting discount.


4.  ESTIMATED OFFERING PRICE AND DIVIDEND 

         The public offering price per share is currently estimated at $25.00
per share. It is currently anticipated that the dividend yield, which is subject
to market and other conditions at the time of the Offering and is based, in
part, upon our preliminary review of the Bank's and Bancorp's financial plans
and prospects, will approximate 9.00% to 9.25% based on the current dividend
yield scenario.


5.  LISTING

         Flagstar Trust's Preferred Securities would be quoted on the National
Association of Securities Dealers, Inc. National Market System and Flagstar
Trust and the Bank would comply with the National Association of Securities
Dealers, Inc.'s (the "NASD") requirements for such quotation.


6.  UNDERWRITING COMPENSATION  

         Assuming the gross proceeds from the sale of Flagstar Trust's Preferred
Securities in the Offering is $65,000,000 the underwriting discount will be
3.15%. If any or all of the over-allotment is exercised, the underwriting
discount will be 3.15% on the over-allotment shares.


7.  REGISTRATION STATEMENT  

         The Offering would be subject to compliance with the Securities Act of
1933, as amended (the "Act"), the Office of Thrift Supervision (the "OTS") and
other applicable federal and state laws and regulations, including, without
limitation, "Blue Sky" laws. The Bank and Flagstar Trust, working with its
counsel, would prepare and file the appropriate registration

statement (the "Registration Statement"). The Registration Statement
(anticipated to be on Form S-3) would conform to the requirements of applicable
laws, the Act and the rules and regulations of the SEC and OTS. Flagstar Trust
would use its best efforts to file such amendments with the SEC and OTS as may
be necessary to have the Registration Statement declared effective by the SEC
as promptly as practicable.


8.  OFFERING EXPENSES  

         Flagstar Trust, Bancorp and the Bank will be jointly and severally
liable for all expenses and fees incurred in connection with the proposed
financing, including but not limited to, fees and expenses related to preparing,
printing and filing of the Registration Statement, all amendments and
supplements thereto, the preliminary and final prospectus, other related
underwriting and selling documents, and certificates for the Preferred
Securities and for accounting, legal, SEC, NASD, appraisal and listing fees. In
addition to the underwriting discount, Bancorp, the Bank and Flagstar Trust also
agree to pay the out-of-pocket expenses, including road show expenses and
underwriters' legal fees (such out-of-pocket expenses payable by Flagstar Trust,
Bancorp and the Bank shall not exceed $75,000 for legal fees and $25,000 for all
other out-of-pocket expenses). In addition, legal fees and disbursements
relating to the "Blue Sky" survey, any required state filing registrations and
the filing fees relating thereto shall be the responsibility of Flagstar Trust.
The underwriters' out-of-pocket expense reimbursement and the Blue Sky legal
fees and disbursements shall be paid regardless of whether the Offering is
completed or not completed for any reason, including market conditions, unless
the Offering is not completed because of the underwriters' refusal (except for
bona fide reasons related to Bancorp, Flagstar Trust, the Bank, or their
officers, directors, employees or agents or market conditions) or inability to
perform. Upon completion of the Offering the Managing Underwriters will agree to
credit the out-of-pocket expense reimbursement (up to a maximum of $100,000)
against the underwriting fee but not the Blue Sky legal fees and disbursements.

         Flagstar Trust, Bancorp and the Bank will be responsible for all of
their own out-of-pocket expenses, including, without limitation, transportation,
meals, and lodging with respect to any road shows and other selling efforts.

         If the Offering does not close for any reason other than the Managing
Underwriters' refusal (except for bona fide reasons related to Flagstar Trust,
Bancorp, the Bank, or their officers, directors, employees or agents or market
conditions) or inability to perform, the underwriters will account for their
reimbursable expenses and will be entitled to reimbursement from Flagstar Trust,
Bancorp and the Bank of such expenses, as described above, including: (i)
documented out-of-pocket expenses relating to the Registration Statement,
including, without limitation, expenses relating to road shows, syndicate
expenses, sales literature expenses and advertising expenses, (ii) documented
underwriters' legal fees (described above) actually incurred. Documented
expenses for "Blue Sky" survey, any required state filing registrations and
filing fees disbursements and expenses, shall be paid directly by Flagstar Trust
and shall not be part of the $100,000 legal fee and out-of-pocket reimbursement
and will be subject to negotiation in advance, between Flagstar Trust and
Honigman Miller Schwartz and Cohn ("Blue Sky Counsel").

FLAGSTAR TRUST   
LETTER OF INTENT 
FEBRUARY 15, 1999
PAGE 4 OF 6

         Flagstar Trust shall have the right to cancel the Offering or terminate
this Letter of Intent at any time without further recourse; provided, however,
that any such cancellation or termination by Flagstar Trust shall not affect the
Bank's, Bancorp's or Flagstar Trust's obligation to pay the out-of-pocket
expense reimbursements (as capped above, i.e., not to exceed $100,000) and the
legal fees and disbursements of Blue Sky Counsel.


9. SALE OF ADDITIONAL SHARES IN THE PUBLIC MARKET

         For a period of 180 days after the effective date of the Registration
Statement, Bancorp, the Bank and their executive officers and directors would
agree not to make any sales of the Flagstar Trust's Preferred Securities without
the consent of Roney Capital Markets.


10. TIMING OF THE OFFERING  

         We and our counsel are prepared to begin work with Flagstar Trust and
its counsel toward preparation and filing of the Registration Statement with the
SEC as soon as possible. Following the filing of the Registration Statement, we
would move forward promptly with the formation of an underwriting syndicate or
selling group, to include a select group of firms capable of providing
complementary distribution. We would consult with you as to firms to be included
in the syndicate and selling group.

         The marketing program would be designed cooperatively by the Managing
Underwriters and Flagstar Trust, and will reflect the need to balance
management's work schedule with the necessary exposure required for the
underwriting.

         After the initial filing, we would expect that a period of up to four
to six weeks would be required for review by the SEC of the Registration
Statement and any necessary amendments thereto, and that a marketing program
would run simultaneously with SEC review. The marketing program would be
completed prior to the time the Registration Statement is declared effective.


11. AUDITORS AND FINANCIAL STATEMENTS  

         The Registration Statement would contain financial information of
Bancorp, the Bank, and Flagstar Trust. For two years from the effective date of
the Registration Statement, Bancorp would furnish the Managing Underwriters and
investors with quarterly unaudited financial statements and copies of all
reports filed with the SEC covering both Bancorp and Flagstar Trust. The
Managing Underwriters will also require a comfort letter from Grant Thornton,
LLP in relation to the Registration Statement.


12.  ACCESS TO INFORMATION  

         In connection with the preparation of the Registration Statement and
other matters pertaining to the Offering, Bancorp, the Bank and Flagstar Trust,
their officers, accountants and counsel shall furnish to us and our counsel on a
timely basis for our use in connection with the Offering such information and
documents as we or they may reasonably request. In addition,

management would be available for consultation and meetings until the closing of
the Offering.






13.  UNDERTAKING TO GIVE NOTICE OF EVENTS  

         In providing this letter, we have assumed no material changes from the
information provided us to date and that no information of a material adverse
nature may come up in the completion of due diligence. Until the signing of the
Underwriting Agreement, Flagstar Trust and the Bank will notify us of any
business or operating events which might materially adversely affect the
Offering or the status of Bancorp, the Bank, or Flagstar Trust and will give
serious consideration to the Managing Underwriters' recommendation as to the
required disclosures relating thereto.


14. UNDERWRITING AGREEMENT  

         The terms of the Offering would be negotiated between the Managing
Underwriters and Flagstar Trust immediately prior to the effective date of the
Registration Statement. Matters regarding the Offering and other matters between
Flagstar Trust and Bancorp and the Managing Underwriters, would be subject to
the terms and conditions of an Underwriting Agreement to be signed concurrently
with the effective date of the Registration Statement. The Underwriting
Agreement would contain terms and conditions usual and customary for a
transaction of this nature, as negotiated between Flagstar Trust and Bancorp and
the Managing Underwriters, including indemnification and contribution clauses
acceptable to Flagstar Trust, Bancorp and the Managing Underwriters.


15. NON-BINDING LETTER  

         This Letter of Intent is only a brief outline of the proposed financing
and, with the exception of paragraph 8, is merely an expression of our present
intention concerning the proposed Offering along the lines indicated. While it
is the present mutual intention of the parties that a public offering of
Flagstar Trust's Preferred Securities be made, this Letter of Intent shall not
in any way be construed as a commitment by the Managing Underwriters to proceed
with a public offering or purchase or sell the Preferred Securities and the
Managing Underwriters may, in their sole judgment and discretion, determine at
any time not to proceed with the Offering, in which event no party shall have
any liability under this Letter of Intent, except as otherwise provided in
paragraph 8. With the exception of paragraph 8 which shall be enforceable in
accordance with its terms, this Letter of Intent does not constitute a binding
contract or represent or create any legally binding obligations of the Managing
Underwriters, Bancorp, the Bank, Flagstar Trust or any of their partners,
officers, directors, agents or affiliates, which obligations would arise only
upon the signing of a definitive Underwriting Agreement.

         With the exception of paragraph 8 the Offering is conditioned in its
entirety upon, and a binding contract will come into existence only upon,
execution and delivery of the Underwriting

Agreement between the Managing Underwriters, Flagstar Trust and Bancorp in form

indemnification and a tax opinion from Grant Thornton, LLP or counsel acceptable
to the Managing Underwriters relating to, among other things, the tax status of
Flagstar Trust.

(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 


<PAGE>   2

         agree that the Trust shall issue and sell to the several Underwriters,
         and the Underwriters agree, severally and not jointly, to purchase from
         the Trust, at a purchase price of $25.00 per Preferred Security (the
         "Purchase Price"), the Firm Preferred Securities each in the amount set
         forth in Schedule A. Because the proceeds from the sale of the
         Preferred Securities will be used to purchase from the Company its
         Debentures (as hereinafter defined and as described in the Prospectus),
         the Company shall pay to the Underwriters a commission as described in
         Section 3 (the "Preferred Securities Commission").

                  In addition, on the basis of the representations, warranties
         and agreements herein contained and subject to the terms and conditions
         herein set forth, the Trust hereby grants to the Underwriters an option
         to purchase all or any portion of the 390,000 Option Preferred
         Securities, and upon the exercise of such option in accordance with
         this Section 1, the Offerors hereby agree that the Trust shall issue
         and sell to the Underwriters, and the Underwriters agree to purchase
         from the Trust, all or any portion of the Option Preferred Securities
         at the same Purchase Price per Preferred Security paid for the Firm
         Preferred Securities. Because the proceeds from the sale of the Firm
         Preferred Securities will be used to purchase from the Company its
         Debentures, the Company shall pay to the Underwriters the Preferred
         Securities Commission described in Section 3 for each Option Preferred
         Security purchased. 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 Preferred Securities,
         and may only be exercised with the express written consent of Roney
         Capital Markets, a division of First Chicago Capital Markets, Inc. (the
         "Representative"). The Option may be exercised in whole or in part at
         any time (but not more than once) by the Underwriters by the
         Representative giving notice (confirmed in writing) to the Trust
         setting forth the number of Option Preferred Securities as to which the
         Underwriters are exercising the Option and the time, date and place for
         payment and delivery of certificates for such Option Preferred
         Securities. Such time and date of payment and delivery for the Option
         Preferred Securities (the "Option Closing Date") shall be determined by
         the Underwriters, 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 the Preferred Securities
         Commission and delivery of certificates for the Firm Preferred
         Securities shall be made at the offices of Honigman Miller Schwartz and
         Cohn, counsel for the Underwriters, 2290 First National Building,
         Detroit, Michigan 48226, or such other place as shall be agreed to by
         the Underwriters and the Offerors, at 10:00 a.m., Eastern time, on
         ___________, 1999, or at such other time not more than five full
         business days thereafter as the Offerors and the Underwriters shall
         determine (the "Closing Date"). If the Underwriters exercise the Option
         to purchase any or all of the Option Preferred Securities, payment of
         the Purchase Price and the Preferred Securities Commission and delivery
         of certificates for such Option Preferred Securities shall be made on
         the Option Closing Date at the Underwriter's offices, or at such other
         place as the Offerors and the Underwriter shall determine. Such
         payments shall be made to an account designated or on behalf of by the
         Trust by wire transfer or certified or bank cashier's check, in
         clearing house or similar 


                                       2

         next day available funds in the amount of the Purchase Price therefor,
         against delivery by or on behalf of the Trust to the Underwriters of
         certificates for the Designated Preferred Securities to be purchased by
         the Underwriters.

                  The Agreement contained herein with respect to the timing of
         the Closing Date and the 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 Designated Preferred Securities to be
         purchased hereunder shall be in book-entry form and registered in the
         name of Cede & Co. not later than 12:00 noon, Eastern time, two
         business days prior to the Closing Date and, if applicable, the Option
         Closing Date. Delivery of the Preferred Securities may be made by
         credit through full fast transfer to the accounts at The Depository
         Trust Company ("DTC") designated by you and if not made by such credit
         delivery with will be made to DTC. Certificates for Designated
         Preferred Securities to be purchased by or on behalf of the
         Underwriters and registered in the name of Cede & Co. shall be made
         available by the Offerors to the Underwriters for inspection, checking
         and packaging at such office as the Underwriters may designate in
         writing not later than 1:00 p.m., Eastern 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 Designated Preferred Securities at the time and place specified
         pursuant to this Agreement is a further condition of the obligations of
         the Underwriters hereunder.

                  (b)     The Offerors propose that the Trust issue the 
         Designated Preferred Securities pursuant to a Trust Agreement among,
         ______________ Trust Company, as Delaware Trustee,
         _____________________________, as the Property Trustee, the
         Administrative Trustees named therein, (collectively, the "Trustees"),
         and the Company, in substantially the form heretofore delivered to the
         Underwriters, said Agreement being hereinafter referred to as the
         "Trust Agreement." In connection with the issuance of the Designated
         Preferred Securities, the Company proposes (i) to issue its Junior
         Subordinated Debentures (the "Debentures") pursuant to an Indenture, to
         be dated as of __________________, 1999, between the Company and
         _____________________, as Trustee (the "Indenture") and (ii) to
         guarantee certain payments on the Preferred Securities pursuant to a
         Preferred Securities Guarantee Agreement between the Company and
         ______________________, as Guarantee Trustee (the "Guarantee"), to the
         extent described therein.

                  (c)     The Representative hereby represents and warrants to 
         the Offerors that it has the authority to enter into this Agreement on
         behalf of the several Underwriters and that the Underwriters have
         indicated their intention to the Representative their willingness to
         purchase severally and not jointly Designated Preferred Securities as
         provided herein.

2.       REPRESENTATIONS AND WARRANTIES.

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

                          (i)     The reports filed with the Securities and 
                  Exchange Commission (the "Commission") by the Company under
                  the Securities Exchange Act of 1934, as amended (the "1934
                  Act") and the rules and regulations thereunder (the "1934 Act
                  Regulations") and incorporated into the Prospectus by
                  reference, 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 fact or omit to state
                  any 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-3 (File Number
                  333-______) for the registration of $65,000,000 aggregate
                  amount of the Designated Preferred Securities, the Guarantee
                  and Debentures under the Securities Act of 1933, as amended
                  (the "1933 Act"), including the related preliminary prospectus
                  subject to completion included therein, and one or more
                  amendments or supplements to such registration statement may
                  have been so filed, in each case in conformity with the
                  requirements of the 1933 Act, the rules and regulations
                  promulgated thereunder (the "1933 Act Regulations") and the
                  Trust Indenture Act of 1939, as amended (the "Trust Indenture
                  Act") and the rules and regulations thereunder. Copies of such
                  registration statement, including any amendments thereto, each
                  Preliminary Prospectus (as defined herein) contained therein
                  and the exhibits, financial statements and schedules to such
                  registration statement, as finally amended and revised, have
                  heretofore been delivered by the Offerors to the Underwriters.
                  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 the form most
                  recently included in an amendment to such registration
                  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 permitted by Rule 424(b) of the 1933 Act
                  Regulations ("Rule 424(b)") and as have been provided to and
                  not objected to by the Underwriters prior to (or as are agreed
                  to by the Underwriters 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 Underwriters prior to (or is agreed to
                  by the Underwriters subsequent to) the execution of this
                  Agreement. Except as required by applicable law as evidenced
                  by a written opinion of counsel relating thereto, the Offerors
                  will not file any amendment to the registration statement or
                  any amended Preliminary Prospectus 


                                       4

                  or any amendment thereto, of which the Underwriters have not
                  been previously furnished a copy or to which the Underwriters
                  or counsel thereto shall have reasonably objected in writing.
                  As used in this Agreement, the term "Registration Statement"
                  means such registration statement, as amended at the time when
                  it was or is declared effective under the 1933 Act, including
                  (1) all financial schedules and exhibits thereto, (2) all
                  documents (or portions thereof) incorporated by reference
                  therein filed under the 1934 Act, and (3) any information
                  omitted therefrom pursuant to Rule 430A and included in the
                  Prospectus (as hereinafter defined); the term "Preliminary
                  Prospectus" means each preliminary prospectus subject to
                  completion filed with such registration statement or any
                  amendment thereto including all documents (or portions
                  thereof) incorporated by reference therein to documents filed
                  under the 1934 Act (including the preliminary 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) or (4) if no prospectus is required to be filed
                  pursuant to Rule 424(b)(1) or (4), the prospectus included in
                  the Registration Statement, in each case including the
                  financial schedules and all documents (or portions thereof)
                  incorporated by reference therein to documents filed under the
                  1934 Act. The date on which the Registration Statement becomes
                  effective under the 1933 Act is hereinafter referred to as the
                  "Effective Date."

                          (iii)   The documents incorporated by reference in the
                  Preliminary Prospectus or Prospectus when they became
                  effective or were filed with the Commission, as the case may
                  be, complied in all material 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 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.

                          (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
                  fact or omit to state any 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 statements or omissions made in reliance upon and
                  in conformity with information furnished in writing to the
                  Offerors by the Underwriters expressly for inclusion in the
                  Prospectus beneath the heading "Underwriting" and on the cover



                                       5
<PAGE>   6

                  page of the Prospectus with respect to price, underwriting
                  discount and terms of the offering (such information referred
                  to herein as the "Underwriter 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
                  fact or omit to state any 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. At
                  the Effective Date and at all times when the Prospectus is
                  required to be delivered in connection with offers and sales
                  of Designated Preferred Securities, including, without
                  limitation, the Closing Date and, if applicable, the Option
                  Closing Date, the Prospectus, as amended or supplemented, (1)
                  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 (2) did not contain and will not contain an
                  untrue statement of fact or omit to state any 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 Information. (vi) The
                  Company is duly incorporated, validly existing and in good
                  standing under the laws of the State of Michigan, with full
                  corporate 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.

                          (vii)   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 its common securities (the "Common Securities")
                  to the Company pursuant to the Trust Agreement, to issue and
                  sell the Designated Preferred Securities, to enter into and
                  perform its 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 to 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

                  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

                  Offerors, classified as an association taxable as a

                  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.

                          (viii)  The Company has six subsidiaries,  Flagstar 
                  Bank, FSB (the "Bank"), the Trust, Douglas Insurance Agency,
                  Inc. ("DIA"), FSSB Real Estate Development Corporation
                  ("REDC"), Mortgage Video Network, Inc. ("Video"), and First
                  Security Investment Group, Inc. ("Investment"). The Bank, the
                  Trust, DIA, REDC, Video and Investment are hereinafter
                  collectively referred to as the "Subsidiaries". 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 Subsidiaries. The
                  Bank is a federally chartered stock savings bank, validly
                  existing and in good standing under the federal Home Owners'
                  Loan Act. The Bank has full corporate 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. The 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
                  the Bank are insured by the Savings Association Insurance Fund
                  ("SAIF") administered by the Federal Deposit Insurance
                  Corporation (the "FDIC") up to the maximum amount provided by
                  law; and no proceedings for the modification, termination or
                  revocation of any such insurance are pending or, to the
                  knowledge of the Offerors, threatened.

                          (ix)    The Company, the Bank, DIA, REDC, Video and 
                  Investment are each duly qualified to transact business as a
                  foreign corporation and are each 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 financial
                  condition, earnings, business, prospects or results of
                  operations of the Company and the Subsidiaries on a
                  consolidated basis. All of the issued and outstanding shares
                  of capital stock of the Subsidiaries (A) have been duly
                  authorized and are validly issued, (B) are fully paid and
                  nonassessable 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 


                                       7

                  instruments convertible into or exchangeable for any capital
                  stock or equity securities of the Subsidiaries.

                          (x)     The capital stock of the Company and the 
                  equity securities of the Trust conform to the description
                  thereof contained in the Prospectus or the financial
                  information included therein (or, if the Prospectus is not in
                  existence, the most recent Preliminary Prospectus). The
                  outstanding shares of capital stock and equity securities of
                  each Offeror 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 an Offeror; no person has any preemptive or
                  similar right to purchase any shares of capital stock or
                  equity securities 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 from the Offerors any
                  securities of the Offerors other than options and warrants
                  issued under the Company's 1997 Employees and Directors 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 or equity securities of the Trust
                  pursuant to the Company's corporate charter or bylaws, the
                  Trust Agreement or any agreement or other instrument to which
                  an Offeror is a party or by which an Offeror is bound.

                          (xi)    (A)     The Trust has all  requisite  power 
                          and authority to issue, sell and deliver the
                          Designated Preferred Securities in accordance with and
                          upon the terms and conditions set forth in this
                          Agreement, the Trust Agreement, the Registration
                          Statement and the Prospectus (or, if the Prospectus is
                          not in existence, the most recent Preliminary
                          Prospectus). All corporate and trust action required
                          to be taken by the Offerors for the authorization,
                          issuance, sale and delivery of the Designated
                          Preferred Securities in accordance with such terms and
                          conditions has been validly and sufficiently taken.
                          The Designated Preferred Securities, 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 in all material respects 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 Trust Agreement. None of the Designated Preferred
                          Securities, 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.

                                  (B)     The Debentures have been duly and 
                          validly authorized, and, when duly and validly
                          executed, authenticated and issued as provided in the
                          Indenture and delivered to the Trust pursuant to the
                          Trust Agreement, will constitute valid and legally
                          binding obligations of the 


                                       8

                          Company entitled to the benefits of the Indenture and
                          will conform in all material respects to the
                          description thereof contained in the Prospectus.

                                  (C)     The Guarantee has been duly and 
                          validly authorized, and, when duly and validly
                          executed and delivered to the Guarantee Trustee for
                          the benefit of the Trust, will constitute a valid and
                          legally binding obligation of the Company and will
                          conform in all material respects to the description
                          thereof contained in the Prospectus.

                                  (D)     The Agreement as to Expenses and 
                          Liabilities (the "Expense Agreement") has been duly
                          and validly authorized, and, when duly and validly
                          executed and delivered by the Company, will constitute
                          a valid and legally binding obligation of the Company
                          and will conform in all material respects to the
                          description thereof contained in the Prospectus.

                          (xii)   The Offerors and the Subsidiaries have 
                  complied 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 except for such
                  matters as would not be expected to have a materially adverse
                  effect thereon.

                         (xiii)   The Offerors and the Subsidiaries have all 
                  governmental and regulatory permits, easements, consents,
                  licenses, franchises and other 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,
                  except as such matters that would not have a material adverse
                  effect on the Offerors and the Subsidiaries or their financial
                  condition, earnings, business, prospects or results of
                  operations. All such Permits are in full force and effect and
                  each of the Offerors and the Subsidiaries are complying
                  therewith in all material respects, 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
                  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)
                  except as such matters that would not have a material adverse
                  effect on the Offerors and the Subsidiaries or their financial
                  condition, earnings, business, prospects or results of
                  operations. Such Permits contain no restrictions that would
                  materially impair the ability of the Company or the
                  Subsidiaries to conduct their businesses in the manner
                  consistent with their past practices. Neither of the Offerors
                  nor any of the Subsidiaries has received notice or otherwise
                  has knowledge of any proceeding or action relating to the
                  revocation or modification of any such Permit.

                  Subsidiaries is in breach or violation of their corporate
                  charter, bylaws or other governing documents (including
                  without limitation, the Trust Agreement). Neither of the
                  Offerors nor any of the Subsidiaries is, 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 would
                  reasonably be expected to have a material adverse effect on
                  the Offerors and the Subsidiaries on a consolidated basis, and
                  to the knowledge of the Offerors, no other party has asserted
                  that the Offerors or any of the Subsidiaries is in such
                  violation, breach or default (provided that the foregoing
                  representations in clause (A) shall not apply to defaults by
                  borrowers from the Bank), 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 Subsidiaries or any of their respective properties the
                  breach, violation or default of which would have a material
                  adverse effect on the financial condition, earnings, business,
                  prospects or results of operations of the Offerors and the
                  Subsidiaries on a consolidated basis.

                         (xv)     The execution,  delivery and performance of 
                  this Agreement and the consummation of the transactions
                  contemplated by this Agreement, the Trust Agreement, the
                  Guarantee, the Expense Agreement, the Registration Statement
                  and the Prospectus (or, if the Prospectus is not in existence,
                  the most recent Preliminary Prospectus) do not and will not
                  conflict with, result in the creation or imposition of any
                  lien, claim, charge, encumbrance or restriction upon any
                  property or assets of the Offerors or the Subsidiaries or the
                  Designated Preferred Securities 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 or bylaws of the
                  Company or the Subsidiaries, the Trust Agreement, the
                  Guarantee, the Expense Agreement, the Indenture, 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 Subsidiaries is a
                  party or by which any 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 instrumentality, domestic or foreign,
                  having jurisdiction over the Offerors or the Subsidiaries 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
                  financial condition, earnings, business, prospects or results
                  of operations of the Offerors and the Subsidiaries on a
                  consolidated basis. No authorization, approval, consent or

                  applicable securities laws or public policy. Each of the
                  Indenture, the Trust Agreement and the Guarantee has been duly
                  qualified under the Trust Indenture Act and will conform in
                  all material respects to the description thereof contained in

                  other defects except such as are referred to in or are

                  hold real or personal property are valid, existing and
                  enforceable leases and in full force and effect and do not
                  interfere with the use made or proposed to be made of such
                  real or personal property, and neither the Company nor any of
                  the Subsidiaries is in default of any of the terms or

                  Subsidiaries or their financial condition, earnings, business,
                  prospects or results of operations.

                          order or decree which would have a material adverse
                          effect on the financial condition, earnings, business,
                          prospects or results of operations of the Offerors and
                          the Subsidiaries on a consolidated basis;

                                  (B)     there has not been any change in, or

                          transactions, other than in the ordinary course of
                          business which would have a material adverse effect on
                          the financial condition, earnings, business, prospects
                          or results of operations of the Offerors and the
                          Subsidiaries on a consolidated basis;

                                  (D)     neither of the Offerors has declared 
                          or paid any dividend and neither of the Offerors nor
                          any of the Subsidiaries has become delinquent in the
                          payment of principal or interest on any outstanding
                          borrowings; and

                                  (E)     there has not been any change in the 
                          capital stock (except for the exercise of employee
                          stock options issued under the Company's 1997
                          Employees and Directors Stock Option Plan, and

                          other than in the ordinary course of business,
                          short-term borrowings of the Offerors or the
                          Subsidiaries.

                          (xxi)   Except as set forth in the Registration 
                  Statement and the Prospectus (or, if the Prospectus is not in
                  existence, the most recent Preliminary Prospectus), no
                  investigation, action, suit or proceeding is pending or, to
                  the knowledge of the Offerors, threatened, against or
                  affecting the Offerors or the Subsidiaries or any of their
                  respective properties before or 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
                  would have a material adverse effect on the consummation of
                  this Agreement or the transactions contemplated herein or the
                  financial condition, earnings, business, prospects or results
                  of operations of the Offerors and the Subsidiaries on a
                  consolidated basis or which is required to be disclosed in the
                  Registration Statement or the Prospectus (or such Preliminary
                  Prospectus) and is not so disclosed.

                         (xxii)   There are no contracts or other documents 
                  required to be filed as exhibits to the Registration Statement
                  under 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 or incorporated by reference
                  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.

                         (xxiii)  Neither of the Offerors has taken, directly
                  or indirectly, any action designed to result in or which has
                  constituted or which might cause or result in stabilization or
                  manipulation of the price of any security of the Offerors to


                                       13
<PAGE>   14

                  facilitate the sale or resale of the Designated Preferred
                  Securities, and neither of the Offerors is aware of any such
                  action taken or to be taken by any affiliate of the Offerors.

                         (xxiv)   The Offerors and the Subsidiaries own, or
                  possess adequate rights to use, all patents, copyrights,
                  trademarks, service marks, trade names and other rights
                  necessary to conduct the businesses now conducted by them or
                  as described in the Prospectus (or, if the Prospectus is not
                  in existence, the most recent Preliminary Prospectus) and
                  neither of the Offerors nor any of the Subsidiaries has
                  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 financial condition, earnings, business,
                  prospects or results of operations of the Offerors and the
                  Subsidiaries on a consolidated basis, and the Offerors do not
                  know of any basis for any such infringement or conflict.

                         (xxv)    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 Subsidiaries exists or, to the
                  knowledge of the Offerors, is imminent which would reasonably
                  be expected to have a material adverse effect on the financial
                  condition, earnings, business, prospects or results of
                  operations of the Offerors and the Subsidiaries 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
                  any of the Subsidiaries has 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 an adverse effect on the condition (financial
                  or otherwise), earnings, affairs, business, prospects or
                  results of operations of the Company and the Subsidiaries on a
                  consolidated basis.

                         (xxvi)   Each of the Offerors and the Subsidiaries has
                  timely and properly prepared and filed all necessary federal,
                  state, local and foreign tax returns which are required to be
                  filed and has paid all taxes shown as due thereon and has 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 financial condition, earnings, business, prospects or
                  results of operations of the Offerors and the Subsidiaries on
                  a consolidated basis. The Offerors have no knowledge of any
                  tax deficiency which has been or might be assessed against the
                  Offerors or the Subsidiaries which, if the subject of an
                  unfavorable decision, ruling or finding, would have a material
                  adverse effect on the financial condition, earnings, business,
                  prospects or results of operations of the Offerors and the
                  Subsidiaries on a consolidated basis.

                          (xxvii) Each of the contracts, agreements and
                  instruments described or referred to in the Registration
                  Statement or the Prospectus (or, if the Prospectus is 


                                       14
<PAGE>   15

                  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
                  Subsidiaries, enforceable in accordance with its terms, except
                  as the enforcement thereof may be limited by general
                  principles of equity and by bankruptcy, moratorium,
                  reorganization, fraudulent transfer or other laws relating to
                  or affecting creditors rights generally, except as such
                  matters that would not have a material adverse effect on the
                  Offerors or their financial condition, earnings, business,
                  prospects or results of operations. Except as disclosed in the
                  Prospectus (or such Preliminary Prospectus), to the knowledge
                  of the Offerors, no other party to any such agreement is (with
                  or without notice or lapse of time or both) in breach or
                  default thereunder, except as to such matters that would not
                  have a material adverse effect on the Offerors or their
                  financial condition, earnings, business, prospects or results
                  of operations; provided however, that the foregoing shall not
                  apply to defaults by borrowers from the Bank.

                         (xxviii) No relationship, direct or indirect, exists
                  between or among the Offerors or the Subsidiaries, on the one
                  hand, and the directors, officers, trustees, shareholders,
                  customers or suppliers of the Offerors or the Subsidiaries, 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.

                         (xxix)   Except as adequately disclosed in the
                  Registration Statement and the Prospectus (or, if the
                  Prospectus is not in existence, the most recent Preliminary
                  Prospectus), persons with the right to request or require the
                  Offerors or the Subsidiaries 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 Designated Preferred Securities have
                  executed waivers of such rights.

                         (xxx) The Designated Preferred Securities have been
                  approved for quotation on the Nasdaq National Market subject
                  to official notice of issuance.

                         (xxxi) 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 legal restrictions on the ability of the
                  Subsidiaries (A) to pay dividends or make any other
                  distributions on its capital stock or to pay any indebtedness
                  owed to the Offerors, (B) to make any loans or advances to, or
                  investments in, the Offerors or (C) to transfer any of its
                  property or assets to the Offerors.

                         (xxxii) Neither of the Offerors is an "investment
                  company" or a company "controlled" by an investment company as
                  such terms are defined in the Investment Company Act of 1940,
                  as amended (the "Investment Company Act").

                         (xxxiii) Other than due diligence material
                  distributed to the Underwriters, the Offerors have not
                  distributed and will not distribute prior to the Closing Date
                  any prospectus in connection with the offering of the
                  Designated Preferred Securities, 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 Underwriters.

          3.      OFFERING BY THE UNDERWRITERS. After the Registration Statement
becomes effective or, if the Registration Statement is already effective, after
this Agreement becomes effective, the Underwriters propose severally and not
jointly to offer the Designated Preferred Securities for sale to the public upon
the terms and conditions set forth in the Prospectus. Each Underwriter may from
time to time thereafter reduce the public offering price and change the other
selling terms, provided that the proceeds to the Trust shall not be reduced as a
result of such reduction or change.

         Each Underwriter shall be entitled to a commission from the Company of
$0.7875 per Firm Preferred Security sold by such Underwriter. Each Underwriter
shall be entitled to a commission of $0.7875 per Option Preferred Security sold
by such Underwriter.

         Each Underwriter may reserve and sell such of the Designated Preferred
Securities purchased by such Underwriter as such 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 Underwriters 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 several Underwriters 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 after execution 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
         Underwriters of such timely filing.

                 (b)     The Offerors shall notify the Underwriters 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 with
                  the Commission;


                                       16
<PAGE>   17

                         (ii)     of the receipt of any comments or requests 
                  from the Commission relating to the Registration Statement and
                  any 1934 Act documents incorporated by reference therein;

                         (iii)    of any request of the Commission to amend or 
                  supplement the Registration Statement, any Preliminary
                  Prospectus, the Prospectus or the 1934 Act documents
                  incorporated therein by reference or for additional
                  information relating thereto; 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 Designated Preferred Securities 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.

                  (c)      The Offerors shall furnish to the Underwriters, from 
         time to time without charge, as soon as available, as many copies as
         the Underwriters may reasonably request of (i) the registration
         statement as originally filed and of all amendments thereto, in
         executed form, including exhibits, whether filed before or after the
         Registration Statement becomes effective, (ii) all exhibits and
         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 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
         Preferred Securities as contemplated herein and in the Trust Agreement
         and the Prospectus. Except as required by applicable law as evidenced
         by a written opinion of counsel relating thereto, 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 the Underwriters shall not
         previously have been advised in writing and provided a copy a
         reasonable time prior to the proposed filings thereof or to which the
         Underwriters or counsel to the Underwriters shall reasonably object. If
         it is necessary, in the Underwriters' reasonable opinion or in the
         reasonable written opinion of counsel to the Underwriters to amend or
         supplement the Registration Statement or the Prospectus in connection
         with the distribution of the Designated Preferred Securities, 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 the Underwriters, such number of copies as
         the Underwriters may reasonably request of an amendment or amendments
         of, or a supplement or supplements to, the Registration Statement or
         the Prospectus, as the case 


                                       17
<PAGE>   18

         may be (in form and substance reasonably satisfactory to the
         Underwriters and counsel to the Underwriters). 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 fact or to include any
         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 the Underwriters, such
         number of copies as the Underwriters may reasonably request of an
         amendment or amendments of, or a supplement or supplements to, the
         Prospectus (in form and substance satisfactory to the Underwriters and
         counsel to the Underwriters) so that, as so amended or supplemented,
         the Prospectus shall not contain an untrue statement of fact or omit to
         state any 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 the Underwriters and 
         counsel to the Underwriters in order to qualify the Designated
         Preferred Securities for offering and sale under the securities or blue
         sky laws of such jurisdictions as the Underwriters may reasonably
         request and shall continue such qualifications in effect so long as may
         be advisable for distribution of the Designated Preferred Securities;
         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 Designated
         Preferred Securities have been qualified as above. The Offerors will
         notify the Underwriters immediately of, and confirm in writing, the
         suspension of qualification of the Preferred Securities or threat
         thereof in any jurisdiction.

                  (f)    The Offerors shall make generally available to their 
         security holders in the manner contemplated by Rule 158 of the 1933 Act
         Regulations and furnish to the Underwriters as soon as practicable, but
         in any event not later than 16 months after the Effective Date, a
         consolidated earnings statement of the Offerors conforming with the
         requirements of Section 11(a) of the 1933 Act and Rule 158.

                  (g)    The Offerors shall use the proceeds from the sale of 
         the Designated Preferred Securities to be sold by the Trust hereunder
         in the manner specified in the Prospectus under the caption "Use of
         Proceeds."

                  (h)    For five years from the Effective Date, the Offerors 
         shall furnish to the Underwriters copies of all reports and
         communications (financial or otherwise) furnished by the Offerors to
         the holders of the Designated Preferred Securities 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.


                                       18
<PAGE>   19

                  (i) For a period of 180 days from the Effective Date, the 
         Offerors, the Bank and their executive officers and directors shall
         not, directly or indirectly, offer for sale, sell or agree to sell or
         otherwise dispose of any Designated Preferred Securities other than
         pursuant to this Agreement, any other beneficial interests in the
         assets of the Trust or any securities of the Trust or the Company that
         are substantially similar to the Preferred Securities, including any
         guarantee of 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 the Representative's prior
         written consent.

                  (j)    The Offerors shall use their best efforts to cause the 
         Designated Preferred Securities 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
         Underwriters, provided this shall not prevent the Company from
         redeeming the Designated Preferred Securities pursuant to the terms of
         the Trust Agreement. If the Designated Preferred Securities are
         exchanged for Debentures, the Company will use its best efforts to have
         the Debentures promptly listed on the Nasdaq National Market or other
         organization on which the Designated Preferred Securities are then
         listed, and to have the Debentures promptly registered under Section 12
         of the Exchange Act.

                  (k)    The Offerors shall not, for a period of 180 days after 
         the date hereof, without the Representative's prior written consent,
         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 the Offerors' securities;
         provided, however, 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 1997 Employees and
         Directors Stock Option Plan.

                  (l)    The Offerors shall not take, directly or indirectly, 
         any action designed to result in or which has constituted or which
         might cause or result in stabilization or manipulation of the price of
         any security of the Offerors to facilitate the sale or resale of the
         Designated Preferred Securities and the Offerors are not aware of any
         such action taken or to be taken by any affiliate of the Offerors.

                  (m)    Prior to the 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 Offerors, the Subsidiaries or
         the offering of the Designated Preferred Securities (the "Offering")
         without the Representative's prior written consent, which will not be
         unreasonably withheld.

         5.       PAYMENT OF EXPENSES. Whether or not this Agreement is 
terminated or the sale of the Designated Preferred Securities to the
Underwriters is consummated, each of the Company, the Bank and the Trust,
jointly and severally, covenants and agrees that it will pay or cause to be paid
(directly or by reimbursement) all costs and expenses incident to the
performance of the obligations of the Offerors under this Agreement, including:

         shipping of the initial registration statement, the Preliminary
         Prospectus or Prospectuses, the Registration Statement and the
         Prospectus and any amendments or supplements thereto, and the printing,
         delivery and shipping of this Agreement and any other underwriting
         documents (including, without limitation, selected dealers agreements),
         the certificates for the Designated Preferred Securities and the
         Preliminary and Final Blue Sky Memoranda and any legal investment
         surveys and any supplements thereto;

                  (b)    all fees, expenses and disbursements of the Offerors' 
         counsel and accountants;

                  (c)    with respect to the Trust only, all fees and expenses 
         incurred in connection with the qualification of the Designated
         Preferred Securities, Debentures and the Guarantee under the securities
         or blue sky laws of such jurisdictions as the Underwriters may request,
         including all filing fees and reasonable fees and disbursements of
         counsel to the Underwriters in connection therewith, including, without
         limitation, in connection with the preparation of the Preliminary and
         Final Blue Sky Memoranda and any legal investment surveys and any
         supplements thereto;

                  (d)    payment to the Representative of its documented 
         expenses up to $75,000 for legal counsel and up to $25,000 for all
         other expenses;

         connection with the listing of the Designated Preferred Securities and,
         if applicable, the Guarantee and the Debentures on the Nasdaq National
         Market;

                  (g)    the cost of furnishing to the Underwriters copies of 
         the initial registration statements, any Preliminary Prospectus, the
         Registration Statement and the Prospectus and all amendments or
         supplements thereto;

                  (h)    the costs and charges of any transfer agent or 
         registrar and the fees and disbursements of counsel to any transfer
         agent or registrar;

                  (i)    all costs and expenses (including stock transfer taxes)
         incurred in connection with the printing, issuance and delivery of the
         Designated Preferred Securities to the Underwriters;

         performance of the obligations of the Company hereunder and under the
         Trust Agreement that are not otherwise specifically provided for in
         this Section 5.


                                       20

         If the sale of Designated Preferred Securities contemplated by this
Agreement is not completed due to a default of this Agreement by the Company
(including a termination pursuant to Section 8(a), (b) or (c)), the Company will
pay the Underwriters their accountable out-of-pocket expenses in connection
herewith or in contemplation of the performance of the Underwriters' obligations
hereunder, including without limitation travel expenses, reasonable fees,
expenses and disbursements of counsel or other out-of-pocket expenses incurred
by the Underwriters in connection with any discussion of the Offering or the
contents of the Registration Statement, any investigation of the Offerors and
the Subsidiaries, or any preparation for the marketing, purchase, sale or
delivery of the Designated Preferred Securities, in each case following
presentation of reasonably detailed invoices therefor.

         6.       CONDITIONS OF THE UNDERWRITERS' OBLIGATIONS. The obligations 
of each of the several Underwriters to purchase and pay for the Firm Preferred
Securities and, following exercise of the Option granted by the Offerors in
Section 1 of this Agreement, the Option Preferred Securities, as set forth in
Schedule A, are subject to the accuracy of and compliance with the
representations and warranties and agreements of the Offerors herein as of the
date hereof and as of the Closing Date (or in the case of the Option Preferred
Securities, if any, as of the Option Closing Date), to the accuracy of the
written statements of the Offerors made pursuant to the provisions hereof, to
the performance by the Offerors of their covenants and obligations hereunder and
to the following additional conditions:

                  (a)    If the  Registration  Statement or any amendment  
         thereto filed prior to the Closing Date has not been declared effective
         prior to the time of execution hereof, the Registration Statement shall
         become effective not later than 10:00 a.m., Eastern time, on the first
         business day following the time of execution of this Agreement, or at
         such later time and date as the Underwriters may agree to in writing.
         If required, the Prospectus and any amendment or supplement thereto
         shall have been timely filed in accordance with Rule 424(b) and Rule
         430A under the 1933 Act and Section 4(a) hereof. No stop order
         suspending the effectiveness of the Registration Statement or any
         amendment or supplement thereto shall have been issued under the 1933
         Act or any applicable state securities laws and no proceedings for that
         purpose shall have been instituted or shall be pending, or, to the
         knowledge of the Offerors or the Underwriters, shall be contemplated by
         the Commission or any state authority. Any request on the part of the
         Commission or any state authority for additional information (to be
         included in the Registration Statement or Prospectus or otherwise)
         shall have been disclosed to the Underwriters and complied with to the
         Underwriters' reasonable satisfaction and to the reasonable
         satisfaction of counsel to the Underwriters.

                  (b)    The Underwriters shall not have advised the Company at

         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 Subsidiaries is duly
                  incorporated, validly existing and in good standing under the

                  there are no outstanding rights, options or warrants to
                  purchase any such shares or securities convertible into or
                  exchangeable for any such shares. The Bank is a member of the
                  Federal Reserve System, and no proceedings for termination or
                  revocation of such membership are pending or, to the best
                  knowledge of such counsel, threatened. The deposit accounts of
                  the Bank are insured by the SAIF up to the maximum amount
                  provided by law, and no proceedings for the termination or
                  revocation of such insurance are pending or, to the best
                  knowledge of such counsel, threatened.

                  behalf of the Trust and is in due and proper form and complies
                  with all applicable requirements. There are no outstanding
                  rights, options or warrants to purchase from the Company, no
                  other outstanding securities convertible into or

                  issue, any shares of capital stock of the Company or equity
                  securities of the Trust, except as described in the
                  Prospectus.

                  power and authority to issue, sell and deliver the Designated
                  Preferred Securities and Debentures in accordance with and

                  Indenture, the Trust Agreement, the Registration Statement and
                  the Prospectus. All corporate or trust action required to be

                  corporate charter, bylaws or other governing documents
                  (including without limitation, the Trust Agreement) of the
                  Offerors or the Subsidiaries, or, to such counsel's knowledge,
                  any agreement or other instrument to which either Offeror or
                  any of the Subsidiaries is a party or by which either Offeror
                  or any of the Subsidiaries may be bound.

                  trust power to enter into and perform their obligations under 
                  this Agreement, and this Agreement has been duly and validly 
                  authorized, executed and delivered by the Offerors and 
                  constitutes the legal, valid and binding obligations of the 
                  Offerors enforceable in accordance with its terms, except as

                         (xvii)   The Trust will be classified for United States
                  federal income tax purposes as a grantor trust and not as an
                  association taxable as a corporation for United States federal
                  income tax purposes, and as a result, each beneficial owner of
                  Preferred Securities (a "Securityholder") will be treated as
                  owning an undivided beneficial interest in the Junior
                  Subordinated Debentures.

                         (xviii)  Unless the Company exercises its option to
                  extend the interest payment period, stated interest on the
                  Junior Subordinated Debentures generally will be included in
                  income by a Securityholder at the time such interest income is
                  paid or accrued in accordance with the Securityholder's
                  regular method of tax accounting.

                         (xix)    Gain or loss will be recognized by a
                  Securityholder on a sale of Preferred Securities (including a
                  redemption for cash) in an amount equal to the difference
                  between the amount realized (which for this purpose, will
                  exclude amounts attributable to accrued interest or original
                  issue discount not previously included in income) and the
                  Securityholder's adjusted tax basis in the Preferred
                  Securities sold or so redeemed. Gain or loss recognized by the
                  Securityholder on Preferred Securities held for more than one
                  year will generally be taxable as long-term capital gain or
                  loss.

                  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 Offerors including, without limitation,
         certificates as to the identity of any and all contracts, indentures,
         mortgages, deeds of trust, loans or credit agreements, notes, leases,
         franchises, licenses or other agreements or instruments, and all
         permits, easements, consents, licenses, franchises and government
         regulatory authorizations, for purposes of paragraphs (viii), (xiii)
         and (xvii) hereof and certificates of public officials. In giving such
         opinion, such counsel may rely as to matters of Delaware law upon the
         opinion of _______________ described herein.

                  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 Offerors and with their independent public accountants and with the
         Underwriters and counsel to the Underwriters, 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 the documents incorporated therein by
         reference and such counsel has no reason to believe (A) that the
         Registration Statement or any amendment thereto (except for the
         financial statements and related schedules and financial and
         statistical data included therein or omitted therefrom or Underwriter
         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 omitted to state 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 (B) that the Prospectus or any amendment
         or supplement thereto or the documents contained therein by reference
         (except for the financial statements and related schedules and
         financial and statistical data included therein or omitted therefrom or
         Underwriter 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 a material fact required to be stated therein
         or necessary to make the statements therein not misleading in light of
         the circumstances under which they were made, or (C) that there is any
         amendment to the Registration Statement required to be filed that has
         not already been filed.

                  (e) ____________________, special Delaware counsel to the 
         Offerors, shall have furnished to the Underwriters their signed
         opinion, dated as of Closing Date or the Option Closing Date, as the
         case may be, in form and substance satisfactory to such counsel, 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 Trust and the Trustees, and is
                  enforceable against the Company, as sponsor, 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 Designated Preferred Securities have been 
                  duly authorized by the Trust Agreement, and when issued and
                  sold in accordance with the Trust Agreement, the Designated
                  Preferred Securities 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. The form of certificates
                  to evidence the Designated Preferred Securities has been
                  approved by the Trust and is in due and proper form and
                  complies with all applicable requirements of the Delaware
                  Business Trust Act.

                         (v)      Holders of Designated Preferred Securities, as
                  beneficial owners of the Trust, will be entitled to the same
                  limitation of personal liability extended to shareholders of
                  private, for-profit corporations organized under the General
                  Corporation Law of the State of Delaware. Such opinion may
                  note that the holders of Designated Preferred Securities 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 Designated Preferred
                  Securities is not subject to preemptive rights.

                         (vii)    The issuance and sale by the Trust of the 
                  Designated Preferred Securities and the Common Securities, 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.

                  (f)    Honigman Miller Schwartz and Cohn, counsel to the 
         Underwriters, shall have furnished to the Underwriters their opinion,
         dated the Closing Date or the Option Closing Date, as the case may be,
         with respect to the sufficiency of all corporate 


                                       28
<PAGE>   29

         proceedings and other legal matters relating to this Agreement, the
         validity of the Designated Preferred Securities, the Registration
         Statement, the Prospectus and such other related matters as the
         Underwriters 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,
         Honigman Miller Schwartz and Cohn may rely as to matters of fact upon
         statements and certifications of officers of the Offerors and of other
         appropriate persons and may rely as to matters of law, other than law
         of the United States and the State of Michigan, upon the opinion of
         _________________ described herein. 

                  (g)    On the date of this Agreement and on the Closing Date, 
         the Underwriters shall have received from Grant Thornton LLP a letter,
         dated the date of this Agreement and the Closing Date (and, if
         applicable, any Option Closing Date), respectively, in form and
         substance satisfactory to the Underwriters, confirming that they are
         independent public accountants with respect to the Company and the
         Bank, 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 Bank audited by them and
                  included in the Registration Statement comply as to form 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 Bank 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 its subsidiary included in the Registration
                  Statement do not comply as to form 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, except as noted in the Registration
                  Statement, with the basis for the audited consolidated
                  financial statements of the Company and its subsidiary
                  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
                  its subsidiary, inspection of the minute books of the Company
                  and the Bank since the date of the latest audited financial
                  statements of the Company and its subsidiary included in the
                  Registration Statement, inquiries of officials of the Company
                  and the Bank 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 its subsidiary, any increase in the
                         consolidated long-term debt, short term borrowings,
                         obligations under capital leases or real estate owned
                         of the Company and its subsidiary, any decreases in
                         consolidated total assets or shareholders equity of the
                         Company and its subsidiary, or any changes, decreases
                         or increases in other items specified by the
                         Underwriters, in each case as compared with amounts
                         shown in the latest unaudited interim consolidated
                         statement of financial condition of the Company and its
                         subsidiary 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 its subsidiary or in the
                         per share amount of net income of the Company and its
                         subsidiary, any increase in consolidated other
                         operating expense of the Company and its subsidiary, or
                         any changes, decreases or increases in any other items
                         specified by the Underwriters, in each case as compared
                         with the comparable period of the preceding year and
                         with any other period of corresponding length specified
                         by the Underwriters, 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
                  Underwriters which are derived from the general accounting
                  records and consolidated financial statements of the Company
                  and its subsidiary which appear in the Registration Statement
                  specified by the Underwriters 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 its subsidiary 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 Underwriters that the Underwriters
         shall have determined, after discussions with officers of the Company
         and the Bank responsible for financial and accounting matters, that
         such changes, decreases, increases or exceptions as are set forth in
         such letters do not (x) reflect an 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 its subsidiary included in the Registration
         Statement, (y) reflect an 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 Underwriters, or (z)
         reflect a material change in items specified in Clause (iv) above from
         the amounts shown in the Preliminary Prospectus distributed by the
         Underwriters in connection with the offering contemplated hereby or
         from the amounts shown in the Prospectus.

                  (h)    At the Closing Date (and, if applicable, the Option 
         Closing Date), the Underwriters 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 in all material respects 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
         financial condition, earnings, business, prospects or results of
         operations of the Offerors and the Subsidiaries on a consolidated
         basis; (iii) since such dates there has not been any transaction
         entered into by the Offerors or the Subsidiaries 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. The officers
         certificate of the Company shall further state that no stop order
         affecting the Registration Statement is in effect or, to their
         knowledge, threatened.

                  (i) At the Closing Date (and, if applicable, the Option 
         Closing Date), the Underwriters shall have received a certificate of an
         authorized representative of the Trust to the effect that to the best
         of his or her knowledge after due investigation, the representations
         and warranties of the Trust in this Agreement are true and correct as
         though made on and as of the Closing Date (and, if applicable, the
         Option Closing Date);


                                       31
<PAGE>   32

         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
         liabilities or obligations, direct or contingent, or entered into any
         transactions not in the ordinary course of business and there has not
         been any adverse change in the condition (financial or otherwise) of
         the Trust.

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

                  (k) The NASD, upon review of the terms of the public offering 
         of the Preferred Securities, shall not have objected to the
         Underwriters' participation in such offering.

                  (l) Prior to the Closing Date, the Offerors shall have 
         furnished to the Underwriters and counsel to the Underwriters 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 the Underwriters. Any certificate signed by an officer
of an Offeror and delivered to the Underwriters pursuant hereto shall also be
deemed to be a representation and warranty of such Offeror to the Underwriters
as to the statements made therein. The Offerors shall furnish to the
Underwriters conformed copies of such opinions, certificates, letters and other
documents as the Underwriters may 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
the several Underwriters' obligations hereunder may be terminated by the
Underwriters on notice to the Company at, or at any time before, the Closing
Date or the Option Closing Date. Any such termination shall be without liability
of the Underwriters to the Offerors.

         7.       INDEMNIFICATION AND CONTRIBUTION.

                  (a)    The Offerors agree to jointly and severally indemnify 
         and hold harmless each of the Underwriters, each of their directors,
         officers and agents, and each person, if any, who controls any
         Underwriter within the meaning of the 1933 Act and the 1934 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 fact made by the
         Company or the Trust contained in the Registration Statement, any
         Preliminary Prospectus or the Prospectus, or in any amendment or
         supplement thereto, (ii) upon any untrue statement or alleged untrue
         statement of fact made by the Company or the Trust 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 


                                       32
<PAGE>   33

         or the Trust filed in any state or other jurisdiction in order to
         qualify any of the Designated Preferred Securities 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, 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), 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 or 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(d); 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 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 the Underwriter Information; provided further that the
         indemnification contained in this paragraph with respect to any
         Preliminary Prospectus shall not inure to the benefit of any
         Underwriter (or of any person controlling such Underwriter) to the
         extent any such losses, claims, damages, liabilities or expenses result
         from the fact that such Underwriter sold Designated Preferred
         Securities 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 such 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)    Each Underwriter severally 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
         Underwriters, but only with respect to the Underwriter Information or
         information furnished by an Underwriter in a Blue Sky Application and
         only for failure to deliver a final prospectus to investors in
         accordance with the 1933 Act. The foregoing indemnity agreement is in
         addition to any liability which any such Underwriter may otherwise have
         to any such indemnified party.


                                       33
<PAGE>   34

                  (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 as separate counsel and the payment of such counsel's fees 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 in writing by such counsel that the
         representation of both parties by the same counsel would be
         inappropriate due to the actual or potential differing interests
         between them (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 be required 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 and shall
         be reasonably acceptable to the indemnifying party. Each indemnified
         party and each controlling person, as a condition of such indemnity,
         shall use reasonable best 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 prior 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.

                  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 


                                       34
<PAGE>   35

         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.

                  (d)    If the indemnification provided for in this Section 7 
         is legally 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
         Underwriters on the other from the offering of the Designated Preferred
         Securities 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 Underwriters 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
         Underwriters on the other shall be deemed to be in the same proportion
         as the total net proceeds from the offering of the Designated Preferred
         Securities (before deducting expenses) received by the Offerors bear to
         the total underwriting discounts, commissions and compensation received
         by the Underwriters, 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 Underwriters on the other shall be determined by
         reference to, among other things, whether the untrue or alleged untrue
         statement of fact or the omission or alleged omission to state a fact
         relates to information supplied by the Offerors or by the Underwriters
         and the parties, relative intent, knowledge, access to information and
         opportunity to correct or prevent such untrue statement or omission.
         The Offerors and each of the Underwriters agree 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), an Underwriter
         shall not be required to contribute any amount in excess of the amount
         by which the total price at which the Designated Preferred Securities
         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.


                                       35
<PAGE>   36

                  For purposes of this paragraph (d), each person who controls
         an Underwriter within the meaning of the 1933 Act shall have the same
         rights to contribution as the Underwriters, and each person who
         controls an Offeror within the meaning of the 1933 Act and the 1934
         Act, each officer and trustee 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 Underwriters under this
         paragraph (d) shall be in addition to any liability that the
         Underwriters 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 Underwriters or any person controlling an Underwriter or by or on
         behalf of the Offerors, or such directors, trustees or officers (or any
         person controlling an Offeror), (ii) acceptance of any Designated
         Preferred Securities and payment therefor hereunder and (iii) any
         termination of this Agreement. A successor of an Underwriter or of an
         Offeror, such directors, trustees or officers (or of any person
         controlling an 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. The Underwriters shall have the right to 
terminate this Agreement at any time at or prior to the Closing Date or, with
respect to the Underwriters' option to purchase the Option Preferred Securities,
at any time at or prior to the Option Closing Date, without liability on the
part of the Underwriters 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 any of the Subsidiaries shall have 
         sustained any 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 Underwriters impairs in
         any material respect the investment quality of the Designated Preferred
         Securities;

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


                                       36
<PAGE>   37

                  (d)    there has occurred any outbreak of hostilities or other
         calamity or crisis or 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
         the Underwriters' reasonable judgment, impracticable to market the
         Designated Preferred Securities or enforce contracts for the sale of
         the Designated Preferred Securities;

                  (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 the Underwriters' reasonable
         judgment, has an 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 Underwriters except as
provided in Sections 5 and 7 hereof.

         9.       DEFAULT BY UNDERWRITERS. If on the Closing Date or the Option 
Closing Date, as the case may be, any Underwriter shall fail to purchase and pay
for the portion of the Firm Preferred Securities, as the case may be, which such
Underwriter has agreed to purchase and pay for on such date otherwise than by
reason of the nonfulfillment of any condition to its obligation to do so
hereunder, you, as Representative of the Underwriters, shall use your best
efforts to procure within 36 hours thereafter one or more of the other
Underwriters, or any others, to purchase such amounts as may be agreed upon, and
upon the terms set forth herein, of the Firm Preferred Securities or Option
Preferred Securities, as the case may be, which the defaulting Underwriter or
Underwriters failed to purchase. If during such 36 hours you, as Representative,
shall not have procured such other Underwriters, or any others, to purchase the
Firm Preferred Securities or Option Preferred Securities, as the case may be,
agreed to be purchased by the defaulting Underwriter or Underwriters, then (a)
if the aggregate number of Preferred Securities with respect to which such
default shall occur does not exceed 10% of the Firm Preferred Securities or
Option Preferred Securities, as the case may be, which they are obligated to
purchase hereunder, you and the other non-defaulting Underwriters each agree to
purchase your pro rata share (based on the number of Preferred Securities which
each non-defaulting Underwriter agreed to purchase hereunder) of the Firm
Preferred Securities or Option Preferred Securities, as the case may be, which
such defaulting Underwriter or Underwriters failed to purchase, or (b) if the
aggregate number of Preferred Securities with respect to which such default
shall occur exceeds 10% of the Firm Preferred Securities or Option Preferred
Securities, as the case may be, covered hereby, you as the Representative of the
Underwriters will have the right, by written notice given within the next
36-hour period to the parties to this Agreement, to terminate this Agreement
without liability on the part of the nondefaulting Underwriters or of the
Offerors except for expenses to be borne by the Offerors and the Underwriters as
provided in Section 5 hereof and the indemnity and contribution agreements in
Section 7 hereof. In the event 


                                       37
<PAGE>   38

of a default by any Underwriter or Underwriters, as set forth in this Section 9,
the Closing Date or Option Closing Date, as the case may be, may be postponed
for such period, not exceeding seven days, as you, as Representative, may
determine in order that the required changes in the Registration Statement or in
the Prospectus or in any other documents or arrangements may be effected. The
term "Underwriter" includes any person substituted for a defaulting Underwriter.
Any action taken under this Section 9 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

                                 TRUST AGREEMENT
                                       OF
                                 FLAGSTAR TRUST

     THIS TRUST AGREEMENT is made as of March 25, 1999 (this "Trust

"Trustees"). The Depositor and the Trustees hereby agree as follows:

     1. The trust created hereby shall be known as "Flagstar Trust" (the

herein, may conduct the business of the Trust, make and execute contracts, and
sue and be sued.

     2. The Depositor hereby assigns, transfers, conveys and sets over to
the Trust the sum of $10. Such amount shall constitute the initial trust estate.
It is the intention of the parties hereto that the Trust created hereby
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code,
12 Del. C. Section 3801, et seq. (the "Business Trust Act"), and that this
document constitute the governing instrument of the Trust. The Trustees are
hereby authorized and directed to execute and file a certificate of trust with
the Delaware Secretary of State in such form as the Trustees may approve.

     3. The Depositor and the Trustees will enter into an Amended and
Restated Trust Agreement satisfactory to each such party to provide for the
contemplated operation of the Trust created hereby and the issuance of the
Preferred or Capital Securities and Common Securities referred to therein. Prior
to the execution and delivery of such Amended and Restated Trust Agreement, (a)
the Trustees shall not have any duty or obligation hereunder or with respect of
the trust estate, except as otherwise required by applicable law and (b) the
Depositor shall take or cause to be taken any action as may be necessary to
obtain prior to such execution and delivery any licenses, consents or approvals
required by applicable law or otherwise. Notwithstanding the foregoing, the
Trustees may take all actions requested by the Depositor that the Depositor
deems necessary, convenient or incidental to effect the transactions
contemplated herein.

     4. The Depositor, as sponsor of the Trust, is hereby authorized, in its
discretion, (i) to prepare and file with the Securities and Exchange Commission
(the "Commission") and to execute, in the case of the 1933 Act Registration
Statement and 1934 Act Registration Statement (as herein defined), on behalf of
the Trust, (a) a Registration Statement (the "1933 Act Registration Statement"),
including all pre-effective and post-effective amendments thereto, relating to
the registration under the Securities Act of 1933, as amended (the "1933 Act"),
of the Preferred or Capital Securities of the Trust, (b) any preliminary
prospectus or prospectus or supplement thereto relating to the Preferred or
Capital Securities of the Trust required to be filed pursuant to the 1933 Act,
and (c) a Registration Statement on Form 8-A or other appropriate form (the
"1934 Act Registration Statement"), including all pre-effective and
post-effective amendments thereto, relating to the registration of the Preferred
or Capital Securities of the Trust under the Securities Exchange Act of 1934, as
amended; (ii) if and at such time as determined by


<PAGE>   2

the Depositor, to file with the New York Stock Exchange or other exchange, or
the National Association of Securities Dealers ("NASD"), and execute on behalf
of the Trust a listing application and all other applications, statements,
certificates, agreements and other instruments as shall be necessary or
desirable to cause the Preferred or Capital Securities of the Trust to be listed
on the New York Stock Exchange or such other exchange, or the NASD's Nasdaq
Stock Market; (iii) to file and execute on behalf of the Trust, such
applications, reports, surety bonds, irrevocable consents, appointments of
attorney for service of process and other papers and documents that shall be
necessary or desirable to register the Preferred or Capital Securities of the
Trust under the securities or "Blue Sky" laws of such jurisdictions as the
Depositor, on behalf of the Trust, may deem necessary or desirable; (iv) to
execute and deliver letters or documents to, or instruments for filing with, a
depository relating to the Preferred or Capital Securities of the Trust; and (v)
to execute, deliver and perform on behalf of the Trust an underwriting agreement
or purchase agreement with one or more underwriters or purchasers relating to
the offering of the Preferred or Capital Securities of the Trust.
     
     In the event that any filing referred to in this Section 4 is required
by the rules and regulations of the Commission, the New York Stock Exchange or
other exchange, NASD, or state securities or "Blue Sky" laws to be executed on
behalf of the Trust by the Trustees, the Trustees, in their capacity as trustees
of the Trust, are hereby authorized to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that the
Trustees, in their capacity as trustees of the Trust, shall not be required to
join in any such filing or execute on behalf of the Trust any such document
unless required by the rules and regulations of the Commission, the New York
Stock Exchange or other exchange, NASD, or state securities or "Blue Sky" laws.

     5. This Trust Agreement may be executed in one or more counterparts.

     6. The number of trustees of the Trust initially shall be two and
thereafter the number of trustees of the Trust 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 of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
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. Subject to the foregoing, the Depositor is entitled to
appoint or remove without cause any trustee of the Trust at any time. Any
trustee of the Trust may resign upon thirty days prior notice to the Depositor.

     7. The Depositor hereby agrees to (i) reimburse the Trustees for all
reasonable expenses (including reasonable fees and expenses of counsel and other
experts) and (ii) indemnify, defend and hold harmless the Trustees and any of
the officers, directors, employees and agents of the Trustees (the "Indemnified
Persons") from and against all losses, damages, liabilities, claims, actions,
suits, costs, expenses, disbursements (including the reasonable fees and
expenses of counsel), taxes and penalties of any kind and nature whatsoever
(collectively, "Expenses"), to the extent that such Expenses arise out of or are
imposed upon or asserted at any time against such Indemnified Persons with
respect to the performance of this Trust Agreement, the creation, operation or
termination of the Trust or the transactions contemplated hereby; provided,
however, that the Depositor shall not be required to indemnify any Indemnified
Person for any Expenses 

                                       2

which are a result of the willful misconduct, bad faith or gross negligence of 
such Indemnified Person.

     8. This Trust Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).

     IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement
to be duly executed as of the day and year first above written.

              than actions which must be taken by or on behalf of the Trust, and

              Trust, and prepare for execution and filing any documents to be
              executed and filed by the Trust or on behalf of the Trust, as the

              file or cause an Administrative Trustee to file thereafter with

                   (iv) if required, the preparation for filing by the Trust
              with the Commission and the execution on behalf of the Trust of a
              registration statement on Form 8-A relating to the registration of
              the Preferred Securities under Section 12(b) or 12(g) of the
              Exchange Act, including any amendments thereto;

                   (v) the negotiation of the terms of, and the execution and
              delivery of, the Underwriting Agreement providing for the sale of
              the Preferred Securities;

                   (vi) the negotiation of the terms of, and execution of, the
              Original Trust Agreement, and the preparation of this Trust
              Agreement and the selection of the Trustee; and

                   (vii) the taking of any other actions necessary or desirable
              to carry out any of the foregoing activities.

              (d) Notwithstanding anything herein to the contrary, the
         Administrative Trustees are authorized and directed to conduct the
         affairs of the Trust and to operate the Trust so that the Trust will
         not be deemed to be an "investment company" required to be registered
         under the Investment Company Act, will be classified as a "grantor
         trust" and not as an association taxable as a corporation for United
         States federal income tax purposes and so that the Junior Subordinated
         Debentures will be treated as indebtedness of the Depositor for United
         States federal income tax purposes. In this connection, subject to
         Section 10.02, the Depositor and the Administrative Trustees are
         authorized to take any action, not inconsistent with applicable law or
         this Trust Agreement, that each of the Depositor and the Administrative
         Trustees determines in their discretion to be necessary or desirable
         for such purposes. In no event shall the Trustees be liable





                                       14
<PAGE>   17

         to the Trust or the Securityholders for any failure to comply with this
         Section that results from a change in law or regulations or in the
         interpretation thereof.

         .8. ASSETS OF TRUST. The assets of the Trust shall consist of the Trust
Property.

         .9. TITLE TO TRUST PROPERTY. Legal title to all Trust Property shall be
vested at all times in the Property Trustee (in its capacity as such) and shall
be held and administered by the Property Trustee for the benefit of the
Securityholders in accordance with this Trust Agreement.

                                  ARTICLE III

                                 PAYMENT ACCOUNT

         .1. PAYMENT ACCOUNT. (a) On or prior to the Closing Date, the Property
Trustee shall establish the Payment Account. The Property Trustee and any agent
of the Property Trustee shall have exclusive control and sole right of
withdrawal with respect to the Payment Account for the purpose of making
deposits and withdrawals from the Payment Account in accordance with this Trust
Agreement. All monies and other property deposited or held from time to time in
the Payment Account shall be held by the Property Trustee in the Payment Account
for the exclusive benefit of the Securityholders and for distribution as herein
provided, including (and subject to) any priority of payments provided for
herein.

         (b) The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other
payments or proceeds with respect to, the Junior Subordinated Debentures.
Amounts held in the Payment Account shall not be invested by the Property
Trustee pending distribution thereof.

                                   ARTICLE IV

                            DISTRIBUTIONS; REDEMPTION

         .1. 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 _________________, 1999,
and, except during any Extension Period with respect to the Junior Subordinated
Debentures, shall be payable quarterly in arrears on the 15th day of March,
June, September and December in each year, commencing June 15, 1999. The amount
of each Distribution due with respect to the Trust Securities will include
amounts accrued through the date the Distribution payment is due. 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






                                       15
<PAGE>   18

date on which Distributions are payable in accordance with this Section 4.01(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 Junior Subordinated Debentures,
Distributions on the Preferred Securities will be deferred for 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 1st day of the month in which the
relevant Distribution Date occurs.

         .2. REDEMPTION.

         (a) On each Debenture Redemption Date and on the Maturity Date of the
Junior Subordinated 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 Securities 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, or if the Redemption Price cannot
              be calculated prior to the time the notice is required to be sent,
              the estimate of the Redemption Price provided pursuant to the
              Indenture together with a statement that it is an estimate and
              that the actual Redemption Price will be calculated on the third
              Business Day prior to the Redemption Date (and, if an estimate is
              provided, a further notice shall be sent of the actual Redemption
              Price on the date, or as soon






                                       16
<PAGE>   19


              as practicable thereafter, that notice of such actual Redemption
              Price is received pursuant to the Indenture);

                   (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;

                   (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, except as provided in Section 4.02(d)
              below; and

                   (vi) the place or places where Trust Securities are to be
              surrendered for the payment of the Redemption Price.

         (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Junior Subordinated Debentures. Redemptions of the Trust
Securities shall be made and the Redemption Price shall be payable on each
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 10:00 a.m., Michigan time, on the Redemption
Date, subject to Section 4.02(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 4.02(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 Securities 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, but without interest on such
Redemption Price, 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
preceding Business Day, in each case, with the same force and






                                       17
<PAGE>   20

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 4.03(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 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
Securities 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.

         .3. 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 4.02(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





                                       18
<PAGE>   21

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. The existence of
an Event of Default does not entitle the Holders of Preferred Securities to
accelerate the maturity thereof.

         (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.

         .4. PAYMENT PROCEDURES. Payments of Distributions (including Additional
Amounts, if applicable) in respect of the Preferred Securities shall be made by
check mailed to the address of the Person entitled thereto as such address shall
appear on the Securities Register or, if the Preferred Securities are held by a
Clearing Agency, such Distributions shall be made to the Clearing Agency in
immediately available funds, which shall credit the relevant Persons' accounts
at such Clearing Agency on the applicable Distribution Dates. Payments in
respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Property Trustee and the Holder of the Common
Securities.

         .5. TAX RETURNS AND REPORTS. The Administrative Trustees shall prepare
(or cause to be prepared), at the Depositor's expense, and file all United
States federal, state and local tax and information returns and reports required
to be filed by or in respect of the Trust. In this regard, the Administrative
Trustees shall (a) prepare and file (or cause to be prepared and filed) the
appropriate Internal Revenue Service Form required to be filed in respect of the
Trust in each taxable year of the Trust and (b) prepare and furnish (or cause to
be prepared and furnished) to each Securityholder the appropriate Internal
Revenue Service form required to be furnished to such Securityholder or the
information required to be provided on such form. The Administrative Trustees
shall provide the Depositor with a copy 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.

         .6. PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST. Upon receipt under the
Junior Subordinated Debentures of Additional Sums, the Property Trustee, at the
direction of an Administrative Trustee or the Depositor, shall promptly pay any
taxes, duties or governmental charges of whatsoever nature (other than
withholding taxes) imposed on the Trust by the United States or any other taxing
authority.







                                       19
<PAGE>   22

         .7. PAYMENTS UNDER INDENTURE. Any amount payable hereunder to any
Holder of Preferred Securities shall be reduced by the amount of any
corresponding payment such Holder has directly received under the Indenture
pursuant to Section 5.14(b) or (c) hereof.

                                    ARTICLE V

                          TRUST SECURITIES CERTIFICATES

         .1. INITIAL OWNERSHIP. Upon the creation of the Trust and the
contribution by the Depositor pursuant to Section 2.03 and until the issuance of
the Trust Securities, and at any time during which no Trust Securities are
outstanding, the Depositor shall be the sole beneficial owner of the Trust.

         .2. THE TRUST SECURITIES CERTIFICATES. The Preferred Securities
Certificates shall be issued in minimum denominations of $25.00 Liquidation
Amount and integral multiples of $25.00 in excess thereof, and the Common
Securities Certificates shall be issued in denominations of $25.00 Liquidation
Amount and integral multiples of $25.00 in excess thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual signature of at
least one Administrative Trustee. Trust Securities Certificates bearing the
manual signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust, shall be
validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the delivery of such Trust Securities Certificates or did
not hold such offices at the date of delivery of such Trust Securities
Certificates. A transferee of a Trust Securities Certificate shall become a
Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.04, 5.11
and 5.13.

         .3. EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES. On the
Closing Date, the Administrative Trustees shall cause Trust Securities
Certificates, in an aggregate Liquidation Amount as provided in Sections 2.04
and 2.05, to be executed on behalf of the Trust by at least one of the
Administrative Trustees and delivered, without further corporate action by the
Depositor, in authorized denominations.

         .4. REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
CERTIFICATES. The Property Trustee shall keep or cause to be kept, at the office
or agency maintained pursuant to Section 5.08, 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
Register") in which the registrar designated by the Property Trustee (the
"Securities Registrar"), subject to such reasonable regulations as it may
prescribe, shall provide for the registration of Preferred Securities
Certificates and Common Securities Certificates (subject to Section 5.10 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.







                                       20
<PAGE>   23

         Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 5.08, the
Administrative Trustees or any one of them shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date of execution by such Administrative Trustee or
Trustees. The Securities Registrar shall not be required to register the
transfer of any Preferred Securities that have been called for redemption. At
the option of a Holder, Preferred Securities Certificates may be exchanged for
other Preferred Securities Certificates in authorized denominations of the same
class and of a like aggregate Liquidation Amount upon surrender of the Preferred
Securities Certificates to be exchanged at the office or agency maintained
pursuant to Section 5.08.

         Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Property Trustee and the
Securities Registrar duly executed by the Holder or such Holder's attorney duly
authorized in writing. Each Preferred Securities Certificate surrendered for
registration of transfer or exchange shall be canceled and subsequently disposed
of by the Property Trustee in accordance with its customary practice. The Trust
shall not be required to (i) issue, register the transfer of, or exchange any
Preferred 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.

         .5. MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES CERTIFICATES.
If (a) any mutilated Trust Securities Certificate shall be surrendered to 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
save each of them harmless, then in the absence of notice that such Trust
Securities Certificate shall have been acquired by a bona fide purchaser, the
Administrative Trustees, or any one of them, on behalf of the Trust shall
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 issued
pursuant to this Section shall constitute conclusive evidence of an undivided
beneficial interest in the assets of the Trust, as if originally issued, whether
or not the lost, stolen or destroyed Trust Securities Certificate shall be found
at any time.







                                       21
<PAGE>   24

         .6. PERSONS DEEMED SECURITYHOLDERS. 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.

         .7. 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 regular
record date (as provided in Section 4.01(d)) and (b) promptly after receipt by
any Administrative Trustee or the Depositor of a request therefor from the
Property Trustee, such other information as the Property Trustee may reasonably
require 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.

         .8. MAINTENANCE OF OFFICE OR AGENCY. The Administrative Trustees shall
maintain 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, 25 South
Charles Street, Baltimore, Maryland 21203, Attention: Corporate Trust
Administration, 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.

         .9. 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 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






                                       22
<PAGE>   25

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 the Property Trustee. The provisions of
Sections 8.01, 8.03 and 8.06 shall apply to the Property Trustee also in its
role as Paying Agent, for so long as the Property Trustee shall act as Paying
Agent and, to the extent applicable, to any 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.

         .10. 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 12.01 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".

         .11. BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON SECURITIES
CERTIFICATE.

         (a) The Preferred Securities Certificates, upon original issuance, will
be issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to or held on behalf of The Depository Trust Company, the initial
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 5.13. Unless and until
Definitive Preferred Securities Certificates have been issued to beneficial
owners pursuant to Section 5.13:

                   (i) the provisions of this Section 5.11(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;






                                       23
<PAGE>   26

                   (iii) to the extent that the provisions of this Section 5.11
              conflict with any other provisions of this Trust Agreement, the
              provisions of this Section 5.11 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 5.13, the
              initial Clearing Agency will make book-entry transfers among the
              Clearing Agency Participants and will 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.

         .12. NOTICES TO CLEARING AGENCY. To the extent that a notice or other
communication to the Owners is required under this Trust Agreement, unless and
until Definitive Preferred Securities Certificates shall have been issued to
Owners pursuant to Section 5.13, 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.

         .13. DEFINITIVE PREFERRED SECURITIES CERTIFICATES. If (a) the Depositor
advises the Trustees in writing that the Clearing Agency is no longer willing or
able to discharge properly 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






                                       24
<PAGE>   27

acceptable to the Administrative Trustees, as evidenced by the execution thereof
by the Administrative Trustees or any one of them.

         .14. 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 2.09, 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 Junior Subordinated
Debentures fail to declare the principal of all of the Junior Subordinated
Debentures to be immediately due and payable, the Holders of at least 25% in
Liquidation Amount of the Preferred Securities then Outstanding shall have the
right to make such declaration 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 Junior Subordinated Debentures shall become
immediately due and payable, provided that the payment of principal and interest
on such Junior Subordinated Debentures shall remain subordinated to the extent
provided in the Indenture. If, as a result of a Debenture Event of Default, the
Debenture Trustee or the holders of not less than 25% in aggregate outstanding
principal amount of the Junior Subordinated Debentures have declared the Junior
Subordinated Debentures due and payable and if such default has been cured and a
sum sufficient to pay all matured installments due (otherwise than by
acceleration) under the Junior Subordinated Debentures has been deposited with
the Debenture Trustee, then (if the holders of not less than a majority in
aggregate outstanding principal amount of Junior Subordinated Debentures have
not annulled such declaration and waived such default) the Holders of a majority
in aggregate Liquidation Amount of the Preferred Securities may annul such
declaration and waive such default.

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

                                   ARTICLE VI

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

         .1. LIMITATIONS ON VOTING RIGHTS.

         (a) Except as provided in this Section, in Sections 5.14, 8.10 and
10.02 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 Junior 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 Debenture Trustee with respect
to such Junior Subordinated Debentures, (ii) waive any past default which is
waivable under Article Seven of the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Junior Subordinated
Debentures shall be due and payable or (iv) consent to any amendment,
modification or termination of the Indenture or the Junior Subordinated
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 Junior Subordinated 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 Junior 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, 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 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








                                       26
<PAGE>   29

classified as a grantor trust or would be classified as an association taxable
as a corporation for United States federal income tax purposes.

         .2. NOTICE OF MEETINGS. Notice of all meetings of the Holders of
Preferred Securities, stating the time, place and purpose of the meeting, shall
be given by the Property Trustee pursuant to Section 10.08 to each Holder of
Preferred Securities of record, at such Securityholder's 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.

         .3. MEETINGS OF HOLDERS OF PREFERRED SECURITIES. 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 Holders 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 Holders
of the Preferred Securities to vote on any matters as to which the Holders of
the Preferred Securities are entitled to vote. Holders 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 such Securityholders. If a quorum is present at a meeting, an affirmative
vote by the Holders 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 Holders of Preferred Securities of record present, either in
person or by proxy, at such meeting shall constitute the action of the Holders
of the Preferred Securities, unless this Trust Agreement requires a greater
number of affirmative votes.

         .4. 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.

         .5. 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
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.

         .6. 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)






                                       27
<PAGE>   30

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).

         .7. 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 any
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.

         .8. 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 8.01) 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 officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him or her the execution thereof. Where such
execution is by a signer acting in a capacity other than such signer's
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of such signer's 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 Holder of Preferred
Securities may institute a legal proceeding directly against the Depositor under
the Guarantee to enforce its rights under the







                                       28
<PAGE>   31

Guarantee without first instituting a legal proceeding against the Guarantee
Trustee (as defined in the Guarantee), the Trust or any Person.

         .9. 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 VII

                         REPRESENTATIONS AND WARRANTIES

         .1. REPRESENTATIONS AND WARRANTIES OF THE TRUST COMPANY AND THE
PROPERTY TRUSTEE. The Trust Company, in its separate corporate capacity and as
Property Trustee, as of the date hereof, and each successor Property Trustee at
the time of the successor Property Trustee's acceptance of its appointment as
Property Trustee hereunder (the term "Trust Company" being used hereafter in
this Article VII to refer to such successor Property Trustee in its separate
corporate capacity and as Property Trustee), hereby represents and warrants (as
applicable) for the benefit of the Depositor and the Securityholders that:

              (a) the Trust Company is a trust company duly organized, validly
         existing and in good standing under the laws of the United States of
         America;

              (b) the Trust Company has full corporate power, authority and
         legal right to execute, deliver and perform its obligations under this
         Trust Agreement and has taken all necessary action to authorize the
         execution, delivery and performance by it of this Trust Agreement;

              (c) this Trust Agreement has been duly authorized, executed and
         delivered by the Trust Company and constitutes the valid and legally
         binding agreement of the Trust Company enforceable against it in
         accordance with its terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles;

              (d) the execution, delivery and performance by the Trust Company
         of this Trust Agreement has been duly authorized by all necessary
         corporate or other action on the part of the Trust Company and does not
         require any approval of the stockholders of the Trust Company and such
         execution, delivery and performance will not (i) violate the Trust
         Company's charter or by-laws, (ii) violate any provision of, or
         constitute, with or without notice or lapse of time, a default under,
         or result in the creation or imposition of, any Lien on any properties
         included in the Trust Property pursuant to the provisions of, any
         indenture, mortgage, credit agreement, license or other agreement or
         instrument to which the Trust Company is a party or by which it is
         bound, or (iii) violate any law, governmental rule or regulation of the
         United States or the State of Delaware, as the case may be,

                                  ARTICLE VIII

                                  THE TRUSTEES

         .1. 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 such
Trustee's acts or omissions hereunder except as a result of such Trustee's 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 or an Administrative Trustee has duties (including
fiduciary duties) and liabilities relating thereto to the Trust or to the
Securityholders, the Delaware Trustee or 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 or 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 Delaware Trustee and 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 such Securityholder's acceptance of a Trust Security, agrees
that such Securityholder will look solely to the revenue and proceeds from the
Trust Property to the extent legally available for distribution to such
Securityholder as herein provided and that the Trustees are not personally
liable to such Securityholder for any amount distributable in respect of any
Trust Security or for any other liability in respect of any Trust Security. This
Section 8.01(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
negligent failure to act, or its own willful misconduct, except that:

              (i) the Property Trustee shall not be liable for any error of
         judgment made in good faith by an authorized officer of the Property
         Trustee, unless it shall






                                       32
<PAGE>   35

         be proved that the Property Trustee was negligent in ascertaining the
         pertinent facts;

              (ii) the Property 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
         Liquidation Amount of the Trust Securities relating to the time, method
         and place 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 Junior
         Subordinated Debentures and the Payment Account shall be to deal with
         such Property in a similar manner as the Property Trustee deals with
         similar property for its own account, subject to the protections and
         limitations on liability afforded to the Property Trustee under this
         Trust Agreement and the Trust Indenture Act;

              (iv) the Property Trustee shall not be liable for any interest on
         any money received by it except as it may otherwise agree with the
         Depositor and money held by the Property Trustee need not be segregated
         from other funds held by it except in relation to the Payment Account
         maintained by the Property Trustee pursuant to Section 3.01 and except
         to the extent otherwise required by law; and

              (v) the Property Trustee shall not be responsible for monitoring
         the compliance by the Administrative Trustees or the Depositor with
         their respective duties under this Trust Agreement, nor shall the
         Property Trustee be liable for the negligence, default or misconduct of
         the Administrative Trustees or the Depositor.

         .2. CERTAIN NOTICES.

         (a) Within five Business Days after the Property Trustee learns of
occurrence of any Event of Default, the Property Trustee shall transmit, in the
manner and to the extent provided in Section 10.08, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived prior to the
sending of such notice. For purposes of this Section the term "Event of Default"
means any event that is, or after notice or lapse of time or both would become,
an Event of Default.

         (b) The Administrative Trustees shall transmit, to the Securityholders
in the manner and to the extent provided in Section 10.08, notice of the
Depositor's election to begin or further extend an Extension Period on the
Junior Subordinated Debentures (unless such election shall have been revoked)
within the time specified for transmitting such notice to the holders of the
Junior Subordinated Debentures pursuant to the Indenture as originally executed.

         (c) In the event the Depositor elects to accelerate the Maturity Date
in accordance with Section 2.02 of the Indenture, the Property Trustee shall
give notice to each Holder of Trust Securities of the acceleration of the
Maturity Date and the Accelerated Maturity Date not later






                                       33
<PAGE>   36

than five Business Days after the Property Trustee receives the notice provided
in Section 2.02(c) of the Indenture.

         .3. CERTAIN RIGHTS OF PROPERTY TRUSTEE. Subject to the provisions of
Section 8.01:

         (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond, debenture, note, other
evidence of indebtedness 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) 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
Trustee finds the same ambiguous or inconsistent with other provisions contained
herein or (iii) the Property Trustee is unsure of the application of any
provision of this Trust Agreement, then, except as to any matter as to which the
Holders of the Preferred Securities are entitled to vote under the terms of this
Trust Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within 10
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than two Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Securityholders, in
which event the Property Trustee shall have no liability except for its own bad
faith, negligence or willful misconduct;

         (c) any direction or act of the Depositor or the Administrative
Trustees contemplated by this Trust Agreement shall be sufficiently evidenced by
an Officers' Certificate;

         (d) whenever in the administration of this Trust Agreement, the
Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and conclusively rely upon an Officer's
Certificate which, upon receipt of such request, shall be promptly delivered by
the Depositor or the Administrative Trustees;

         (e) the Property Trustee shall have no duty to see to any recording,
filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

         (f) the Property Trustee may consult with counsel of its choice and the
advice of such counsel shall be full and complete authorization and protection
in respect of any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon and in accordance







                                       34
<PAGE>   37

with such advice (such counsel may be counsel to the Depositor or any of its
Affiliates, and may include any of its employees); the Property Trustee shall
have the right at any time to seek instructions concerning the administration of
this Trust Agreement from any court of competent jurisdiction;

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Securityholders pursuant to this Trust Agreement, unless
such Securityholders shall have offered to the Property Trustee such reasonable
security or indemnity as the Property Trustee may request against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

         (h) the Property 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,
debenture, note or other evidence of indebtedness or other paper or document,
unless requested in writing to do so by one or more Securityholders, but the
Property Trustee may make such further inquiry or investigation into such facts
or matters as it may see fit;

         (i) the Property Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through its
agents or attorneys, provided that the Property Trustee shall be responsible for
its own negligence or recklessness with respect to selection of any agent or
attorney appointed by it hereunder;

         (j) whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive instructions with respect to
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, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement. No provision of this
Trust Agreement shall be deemed to impose any duty or obligation on the Property
Trustee to perform any act or acts or exercise any right, power, duty 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 exercise
any such right, power, duty or obligation. No permissive power or authority
available to the Property Trustee shall be construed to be a duty.

         .4. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The
recitals contained herein and in the Trust Securities Certificates shall be
taken as the statements of the Trust, and the






                                       35
<PAGE>   38

Trustees do not assume any responsibility for their correctness. The Trustees
(as such) shall not be accountable for the use or application by the Depositor
of the proceeds of the Junior Subordinated Debentures.

         .5. MAY HOLD SECURITIES. Any Trustee or any other agent of any Trustee
or the Trust, in its individual or any other capacity, may become the owner or
pledgee of Trust Securities and, subject to Sections 8.08 and 8.13 and except as
provided in the definition of the term "Outstanding" in Article I, may otherwise
deal with the Trust with the same rights it would have if it were not a Trustee
or such other agent.

         .6. COMPENSATION; INDEMNITY; FEES. The Depositor agrees:

         (a) to pay to the Trustees from time to time reasonable compensation
for all services rendered by them hereunder (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust);

         (b) except as otherwise expressly provided herein, to reimburse the
Trustees upon request for all reasonable expenses, disbursements and advances
incurred or made by the Trustees in accordance with any provision of this Trust
Agreement (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to such Trustee's negligence, bad faith or
willful misconduct (or, in the case of the Administrative Trustees or the
Delaware Trustee, any such expense, disbursement or advance as may be
attributable to its, his or her gross negligence, bad faith or willful
misconduct); and

         (c) to the fullest extent permitted by applicable law, to indemnify and
hold harmless (i) each Trustees and any predecessor Trustee, (ii) any Affiliate
of any Trustee, (iii) any officer, director, shareholder, employee,
representative or agent of any Trustee, and (iv) any employee or agent of the
Trust, (referred to as an "Indemnified Person") from and against, any loss,
damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person arising out of or in connection
with the creation, operation or dissolution of the Trust or any act or omission
performed or omitted by such Indemnified Person reasonably believed to be within
the scope of authority conferred on such Indemnified Person by this Trust
Agreement, except that no Indemnified Person shall be entitled to be indemnified
in respect of any loss, damage or claim incurred by such Indemnified Person by
reason of gross negligence, bad faith or willful misconduct with respect to such
acts or omissions (or, in the case of the Property Trustee, by reason of
negligence, bad faith or willful misconduct with respect to such acts or
omissions).

         The provisions of this Section 8.06 shall survive the termination of
this Trust Agreement.

         The Depositor and any Trustee may engage in or possess an interest in
other business ventures of any nature or description, independently or with
others, similar or dissimilar to the business of the Trust, and the Trust and
the Holders of Trust Securities shall have no rights by virtue of the Trust
Agreement in and to such independent ventures or the income or profits derived
therefrom, and the pursuit of any such venture, even if competitive with the
business of






                                       36
<PAGE>   39

the Trust, shall not be deemed wrongful or improper. Neither the Depositor nor
any Trustee shall be obligated to present any particular investment or other
opportunity to the Trust even if such opportunity is of a character that, if
presented to the Trust, could be taken by the Trust, and the Depositor or any
Trustee shall have the right to take for its own account (individually or as a
partner of fiduciary) or to recommend to others any such particular investment
or other opportunity. Any Trustee may engage or be interested in any financial
or other transaction with the Depositor or any Affiliate of the Depositor, or
may act as depository for, trustee or agent for, or act on any committee or body
of holders of, securities or other obligations of the Depositor or its
Affiliates.

         No Trustee may claim any Lien on any Trust Property as a result of any
amount due pursuant to this Section 8.06.

         .7. CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

         (a) There shall at all times be a Property Trustee hereunder with
respect to the Trust Securities. The Property Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $500,000 (and its principal parent holding
company having a combined capital and surplus of at least $50 million). If any
such Person publishes reports of condition at least annually, pursuant to law or
to the requirements of its supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such Person shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Property Trustee with
respect to the Trust Securities shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article.

         (b) There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities. Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal
entity that shall act through one or more persons authorized to bind that
entity.

         (c) There shall at all times be a Delaware Trustee with respect to the
Trust Securities. The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal place of business in the State of Delaware and
that otherwise meets the requirements of applicable Delaware law that shall act
through one or more persons authorized to bind such entity.

         .8. CONFLICTING INTERESTS. If the Property Trustee has or shall acquire
a conflicting interest within the meaning of the Trust Indenture Act, the
Property Trustee shall either eliminate such interest or resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust
Indenture Act and this Trust Agreement.

         .9. 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





                                       37
<PAGE>   40

Property may at the time be located, the Depositor and the Administrative
Trustees shall have power to appoint, and upon the written request of the
Property Trustee, the Depositor and the Administrative Trustees 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 and the
Administrative Trustees do not join in such appointment within 15 days after the
receipt by them of a request so to do, or in case a Debenture Event of Default
has occurred and is continuing, the Property Trustee alone shall have power to
make such appointment. Any co-trustee or separate trustee appointed pursuant to
this Section shall either be (i) a natural person who is at least 21 years of
age and a resident of the United States or (ii) a legal entity with its
principal place of business in the United States that shall act through one or
more persons authorized to bind such entity.

         Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, 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





                                       38
<PAGE>   41

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 8.09.

         (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.

         .10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. 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 8.11.

         Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time by giving written notice thereof to the Securityholders.
If the instrument of acceptance by the successor Trustee required by Section
8.11 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 Depositor, any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

         Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Holder of the
Common Securities. 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 such Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Holder of the Common Securities at any time. In no event will
the Holders of the Preferred Securities have the right to vote to appoint,
remove or replace the Administrative Trustees.

         If the Relevant Trustee shall resign, be removed or become incapable of
acting as Trustee, or if a vacancy shall occur in the office of such Relevant
Trustee for any cause, at a time when no Debenture Event of Default shall have
occurred and be continuing, the Holder of the Common Securities, by Act of the
Holder of the Common Securities delivered to the retiring Relevant 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 8.11. 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 Holders of
the Preferred Securities by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities then Outstanding delivered to the retiring
Relevant Trustee, shall promptly appoint a successor Trustee or Trustees, and
such successor Trustee shall comply with the applicable requirements of Section
8.11. If an Administrative Trustee shall resign, be removed






                                       39
<PAGE>   42

or become incapable of acting as Administrative Trustee, at a time when a
Debenture Event of Default shall have occurred and be continuing, the Holder of
the Common Securities, by Act of the Holder of the Common Securities delivered
to an Administrative Trustee, shall promptly appoint a successor Administrative
Trustee or Administrative Trustees, and such successor Administrative Trustee or
Administrative Trustees shall comply with the applicable requirements of Section
8.11. If no successor Trustee with respect to the Trust Securities shall have
been so appointed by the Holder of the Common Securities or the Holders of the
Preferred Securities, as the case may be, and accepted appointment in the manner
required by Section 8.11, any Securityholder who has been a Securityholder for
at least six months may, on behalf of such Securityholder and all others
similarly situated, petition a court of competent jurisdiction for the
appointment of a successor Trustee.

         The Property Trustee shall give notice of each resignation and each
removal of a Relevant Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.08 and shall give notice to
the Depositor. Each notice shall include the name of the successor Trustee and
the address of its Corporate Trust office if it is the Property Trustee.

         Subject to 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 the 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 or the Delaware Trustee, as the case may be, set
forth in Section 8.07).

         .11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. In case of the appointment
hereunder of a successor Trustee, the retiring Relevant Trustee and each
successor Trustee shall execute and deliver an instrument wherein each successor
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 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 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 Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor 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 Trustee, the Trust 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 the
immediately preceding paragraph, as the case may be. 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.







                                       40
<PAGE>   43

         .12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS. Any
Person into which a 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 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.

         .13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR TRUST. If
and when the Property Trustee shall be or become a creditor of the Depositor or
the Trust (or any other obligor upon the Junior Subordinated Debentures or the
Trust Securities), the Property Trustee 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).

         .14. REPORTS BY PROPERTY TRUSTEE.

         (a) Not later than January 31 of each year commencing with January 31,
2000, the Property Trustee shall transmit to all Securityholders in accordance
with Section 10.08, and to the Depositor, a brief report dated as of the
preceding December 31 with respect to:

              (i) its eligibility under Section 8.07 or, in lieu thereof, if to
         the best of its knowledge it has continued to be eligible under said
         Section, a written statement to such effect; and

              (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 may be listed,
with the Commission and with the Depositor.

         .15. REPORTS TO THE PROPERTY TRUSTEE. The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information as required by Section 314 of
the Trust Indenture Act (if any) and the compliance certificate required by
Section 314(a) of the Trust Indenture Act in the form, in the manner and at the
times required by Section 314 of the Trust Indenture Act.

         .16. EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT. Each of the
Depositor and the Administrative Trustees on behalf of the Trust shall provide
to the Property Trustee such






                                       41
<PAGE>   44

evidence of compliance with the 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 Section 314(c)(1) of the Trust Indenture Act
shall be given in the form of an Officers' Certificate.

         .17. NUMBER OF TRUSTEES.

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

              (b) If a Trustee ceases to hold office for any reason and the
number of Administrative Trustees is not reduced pursuant to Section 8.17(a), or
if the number of Trustees is increased pursuant to Section 8.17(a), a vacancy
shall occur. The vacancy shall be filled with a Trustee appointed in accordance
with Section 8.10.

              (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul the Trust. Whenever a vacancy in the number of Administrative Trustees
shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 8.10, the Administrative
Trustees in office, regardless of their number (and notwithstanding any other
provision of this Agreement), shall have all the powers granted to the
Administrative Trustees and shall discharge all the duties imposed upon the
Administrative Trustees by this Trust Agreement.

         .18. DELEGATION OF POWER.

         (a) Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
2.07(a)(i); and

         (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or otherwise as the Administrative Trustees may
deem expedient, to the extent such delegation is not prohibited by applicable
law or contrary to the provisions of the Trust, as set forth herein.

         .19. VOTING. Except as otherwise provided in this Trust Agreement, the
consent or approval of the Administrative Trustees shall require consent or
approval by not less than a majority of the Administrative Trustees, unless
there are only two, in which case both must consent.

                                   ARTICLE IX

                       DISSOLUTION, LIQUIDATION AND MERGER

         .1. DISSOLUTION UPON EXPIRATION DATE. Unless earlier dissolved, the
Trust shall automatically dissolve on ____________________, 2029 (the
"Expiration Date"), and thereafter the Trust Property shall be distributed in
accordance with Section 9.04.

         .2. EARLY DISSOLUTION. The first to occur of any of the following
events is an "Early Termination Event," upon the occurrence of which the Trust
shall dissolve:

              (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 Junior Subordinated Debentures to Securityholders in exchange for
         the Preferred Securities in accordance with Section 9.04;

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

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

         .3. 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 9.04, or upon the
         redemption of all of the Trust Securities pursuant to Section 4.02, 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;

              (c) the discharge of all administrative duties of the
         Administrative 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 cancellation by the
         Administrative Trustee under the Delaware Business Trust Act.

         .4. LIQUIDATION.

         (a) If an Early Termination Event specified in clause (a), (b), or (d)
of Section 9.02 occurs or upon the Expiration Date, the Trust shall be
liquidated by the Trustees as expeditiously





                                       43
<PAGE>   46

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 Junior Subordinated Debentures, subject to
Section 9.04(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 Junior Subordinated Debentures; and

              (iii) provide such information with respect to the mechanics by
         which Holders may exchange Trust Securities certificates for Junior
         Subordinated Debentures, or if Section 9.04(d) applies receive a
         Liquidation Distribution, as the Administrative Trustees or the
         Property Trustee shall deem appropriate.

         (b) Except where Section 9.02(c) or 9.04(d) applies, in order to effect
the liquidation of the Trust and distribution of the Junior Subordinated
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 Junior Subordinated
Debentures in exchange for the Outstanding Trust Securities Certificates.

         (c) Except where Section 9.02(c) or 9.04(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
Subordinated Debenture, subject to the provisions of the Indenture) representing
a Like Amount of Junior Subordinated 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 Junior Subordinated Debentures listed on
the NASDAQ National Market or on such other securities exchange or other
organization as the Preferred Securities may then be listed or traded, (iv) any
Trust Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of Junior Subordinated Debentures, accruing interest at
the rate provided for in the Junior Subordinated 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 or principal will be
made to Holders of Trust Securities Certificates with respect to such Junior
Subordinated Debentures) and (v) all rights of Securityholders holding Trust
Securities will cease, except the right of such Securityholders to receive
Junior Subordinated Debentures upon surrender of Trust Securities Certificates.







                                       44
<PAGE>   47

         (d) In the event that, notwithstanding the other provisions of this
Section 9.04, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Junior Subordinated
Debentures in the manner provided herein is determined by the Property Trustee
not to be practical, the Trust shall be dissolved and the Trust Property shall
be liquidated by the Property Trustee in such manner as the Property Trustee
determines. In such event, on the date of the dissolution 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, 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, 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 with respect to any distributions.

         .5. 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 9.05. 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 Junior Subordinated Debentures, (iii) 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, (iv)
such successor entity has a purpose identical to that of the Trust, (v) the
Successor Securities will be listed or traded on any national securities
exchange or other organization on which the Preferred Securities may then be
listed, (vi) prior to such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, the Depositor has received an Opinion of Counsel
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 the






                                       45
<PAGE>   48

Trust nor such successor entity will be required to register as an "investment
company" under the Investment Company 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.

                                   ARTICLE X

                            MISCELLANEOUS PROVISIONS

         .1. 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, 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.

         .2. 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 8.11 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 Investment Company Act; provided, however,
that in the case of clause (ii), such action shall not adversely affect in any
material respect the interests of 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 6.01(c) or Section 10.02(c) hereof,
any provision of this Trust Agreement may be amended by the Trustees and the
Depositor (i) with the consent of 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





                                       46
<PAGE>   49

States federal income tax purposes or the Trust's exemption from status of an
"investment company" under the Investment Company 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 6.03 or 6.06 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 6.03 or 6.06 hereof),
this paragraph (c) of this Section 10.02 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 Investment Company 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.

         .3. SEPARABILITY. In case any provision in this Trust Agreement or in
the Trust Securities Certificates shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

         .4. GOVERNING LAW. THIS TRUST AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF EACH OF THE SECURITYHOLDERS, THE TRUST AND THE TRUSTEES WITH RESPECT TO THIS
TRUST AGREEMENT AND THE TRUST SECURITIES SHALL BE CONSTRUED IN ACCORDANCE WITH
AND GOVERNED BY THE LAWS OF THE STATE OF DELAWARE (WITHOUT REGARD TO CONFLICT OF
LAWS PRINCIPLES).

         .5. PAYMENTS DUE ON NON-BUSINESS DAY. If the date fixed for any payment
on any Trust Security shall be a day that is not a Business Day, then such
payment need not be made on such date but may be made on the next succeeding day
which is a Business Day (except as





                                       47
<PAGE>   50

otherwise provided in Sections 4.01(a) and 4.02(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.

         .6. SUCCESSORS. This Trust Agreement shall be binding upon and shall
inure to the benefit of any successor to the Depositor, the Trust or the
Relevant Trustee(s), including any successor by operation of law. Except in
connection with a consolidation, merger or sale involving the Depositor that is
permitted under Article Twelve of the Indenture and pursuant to which the

               (a)  In connection with a Dissolution Event:

                    (i)  the Junior  Subordinated  Debentures in certificated
               form may be presented to the Trustee by the Property Trustee in
               exchange for a Global Subordinated Debenture in an aggregate
               principal amount equal to the aggregate principal amount of all
               outstanding Junior Subordinated Debentures (a "Global
               Subordinated Debenture"), to be registered in the name of the
               Depositary, or its 


                                       9

<PAGE>   12


               nominee, and delivered by the Trustee to the Depositary for
               crediting to the accounts of its participants pursuant to the
               instructions of the Administrative Trustees. The Company upon any
               such presentation shall execute a Global Subordinated Debenture
               in such aggregate principal amount and deliver the same to the
               Trustee for authentication and delivery in accordance with this
               Indenture. Payments on the Junior Subordinated Debentures issued
               as a Global Subordinated Debenture will be made to the
               Depositary; and

                    (ii) if any Preferred Securities are held in non book-entry
               certificated form, the Junior Subordinated Debentures in
               certificated form may be presented to the Trustee by the Property
               Trustee and any Preferred Securities Certificate which represents
               Preferred Securities other than Preferred Securities held by the
               Depositary or its nominee ("Non Book-Entry Preferred Securities")
               will be deemed to represent beneficial interests in Junior
               Subordinated Debentures presented to the Trustee by the Property
               Trustee having an aggregate principal amount equal to the
               aggregate Liquidation Amount of the Non Book-Entry Preferred
               Securities until such Preferred Securities Certificates are
               presented to the Securities Registrar for transfer or reissuance
               at which time such Preferred Securities Certificates will be
               canceled and a Junior Subordinated Debenture, registered in the
               name of the holder of the Preferred Securities Certificate or the
               transferee of the holder of such Preferred Securities
               Certificate, as the case may be, with an aggregate principal
               amount equal to the aggregate Liquidation Amount of the Preferred
               Securities 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 Junior
               Subordinated Debentures, Junior Subordinated 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 Subordinated 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.

               (c)  If at any time the Depositary notifies the Company 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 Exchange Act 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 Junior Subordinated Debentures in definitive registered form
     without coupons, in authorized denominations, and in an aggregate principal
     amount equal to the principal amount of the Global Subordinated Debenture
     in exchange for such Global Subordinated Debenture. In addition, the
     Company may at any time determine that the Junior Subordinated Debentures
     shall no longer be represented by a Global Subordinated 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 Junior 


                                       10

<PAGE>   13

     Subordinated Debentures in definitive registered form without coupons, in
     authorized denominations, and in an aggregate principal amount equal to the
     principal amount of the Global Subordinated Debenture in exchange for such
     Global Subordinated Debenture. Upon the exchange of the Global Subordinated
     Debenture for such Junior Subordinated Debentures in definitive registered
     form without coupons, in authorized denominations, the Global Subordinated
     Debenture shall be canceled by the Trustee. Such Junior Subordinated
     Debentures in definitive registered form issued in exchange for the Global
     Subordinated 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 Junior Subordinated Debentures to
     the Depositary for delivery to the Persons in whose names such Junior
     Subordinated Debentures are so registered.

     .5.    INTEREST.

               (a)  Each Junior Subordinated Debenture will bear interest at
     the rate of __% per annum (the "Coupon Rate") from the original date of
     issuance until the principal thereof becomes due and payable, and on any   
     overdue principal and (to the extent that payment of such interest is
     enforceable under applicable law) on any overdue installment of interest
     at the Coupon Rate, compounded quarterly, payable (subject to the
     provisions of Article IV) quarterly in arrears on the fifteenth day of
     March, June, September and December in each year (each, an "Interest
     Payment Date"), commencing on June 15, 1999, to the Person in whose name
     such Junior Subordinated Debenture or any Predecessor Junior Subordinated
     Debenture is registered at the close of business on the regular record
     date for such interest installment, which, in respect of (i) Junior
     Subordinated Debentures of which the Property Trustee is the Holder and
     the Preferred Securities are in book-entry-only form or (ii) a Global
     Subordinated Debenture, shall be the close of business on the Business Day
     next preceding that Interest Payment Date. Notwithstanding the foregoing
     sentence, if (A) the Junior Subordinated Debentures are held by the
     Property Trustee and the Preferred Securities are no longer in book-entry
     only form or (B) the Junior Subordinated Debentures are not represented by
     a Global Subordinated Debenture, the record date for such interest
     installment shall be the first day of the month in which such payment is
     to be made. The amount of each interest payment due with respect to the
     Junior Subordinated Debentures will include amounts accrued through the
     date the interest payment is due.

               (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 quarterly period. In the event that any date on which interest is payable
     on the Junior Subordinated 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.

                                       11

<PAGE>   14

               (c)  If, at any time while the Property Trustee is the Holder of
     any Junior Subordinated 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 Sums") on the Junior Subordinated
     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.

     .6.    EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The Junior 
Subordinated Debentures shall be executed on behalf of the Company by its Chief
Executive Officer, its President or any Vice President and attested by its
Secretary or Assistant Secretary. The signature of any of these officers on the
Junior Subordinated Debentures may be manual or facsimile.

     Junior Subordinated Debentures bearing the manual or facsimile signatures
of individuals who were at any time the proper officers of the Company shall
bind the Company, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication and delivery of such
Junior Subordinated Debentures or did not hold such offices at the date of such
Junior Subordinated Debentures.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Junior Subordinated Debentures executed by
the Company to the Trustee for authentication, together with a Company order for
the authentication and delivery of such Junior Subordinated Debentures. The
Trustee in accordance with such Company order shall authenticate and deliver
such Junior Subordinated Debentures as provided in this Indenture and not
otherwise.

     Upon the initial issuance, each Junior Subordinated Debenture shall be
dated March__, 1999, and thereafter Junior Subordinated Debentures issued
hereunder shall be dated the date of their authentication.

     No Junior Subordinated Debenture shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless there appears on
such Junior Subordinated Debenture a certificate of authentication substantially
in the form provided for herein executed by the Trustee by manual signature, and
such certificate upon any Junior Subordinated Debenture shall be conclusive
evidence, and the only evidence, that such Junior Subordinated Debenture has
been duly authenticated and delivered hereunder and is entitled to the benefits
of this Indenture.

     .7.    REGISTRATION AND TRANSFER. The Company shall cause to be kept at the
Corporate Trust Office of the Trustee a register (the register maintained in
such office or any other office or agency pursuant to Section 5.02 being herein
sometimes referred to as the "Securities Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of the Junior Subordinated Debentures and transfers of the Junior



                                       12

<PAGE>   15

Subordinated Debentures. The Trustee is hereby appointed "Securities Registrar"
for the purpose of registering the Junior Subordinated Debentures and transfers
of the Junior Subordinated Debentures as herein provided.

     Upon surrender for registration of transfer of any Junior Subordinated
Debenture at an office or agency of the Company designated pursuant to Section
5.02 for such purpose, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, a new Junior Subordinated Debenture of the authorized denomination.

     All Junior Subordinated Debentures issued upon any registration of transfer
of Junior Subordinated Debentures shall be valid obligations of the Company,
evidencing the same debt and entitled to the same benefits under this Indenture
as the Junior Subordinated Debentures surrendered upon such registration of
transfer.

     Every Junior Subordinated Debenture presented or surrendered for
registration of transfer shall be duly endorsed for transfer (if so required by
the Company or the Trustee), or shall be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Securities Registrar duly
executed by the Holder thereof or such Holder's attorney duly authorized in
writing.

     No service charge shall be made for any registration of transfer of Junior
Subordinated Debentures, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer of Junior Subordinated Debentures.

     The Company shall not be required to issue or register the transfer of any
Junior Subordinated Debenture during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Junior Subordinated Debentures selected for redemption pursuant to Article III
and ending at the close of business on the day of such mailing.

     .8.    MUTILATED, DESTROYED, LOST AND STOLEN JUNIOR SUBORDINATED 
DEBENTURES. If any mutilated Junior Subordinated Debenture is surrendered to the
Trustee, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Junior Subordinated Debenture of like tenor
and principal amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (a) evidence to
their satisfaction of the destruction, loss or theft of any Junior Subordinated
Debenture and (b) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Junior Subordinated Debenture has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Junior
Subordinated Debenture, a new Junior Subordinated Debenture of like tenor and
principal amount and bearing a number not contemporaneously outstanding.


                                       13
<PAGE>   16


     In case any such mutilated, destroyed, lost or stolen Junior Subordinated
Debenture has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Junior Subordinated Debenture, pay such
Junior Subordinated Debenture.

     Upon the issuance of any new Junior Subordinated Debenture under this
Section, the Company may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee) connected
therewith.

     Every new Junior Subordinated Debenture issued pursuant to this Section in
lieu of any destroyed, lost or stolen Junior Subordinated Debenture shall
constitute an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Junior Subordinated Debenture shall be at
any time enforceable by anyone, and shall be entitled to all of the benefits of
this Indenture.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Junior Subordinated Debentures.

                                  ARTICLE III

                  REDEMPTION OF JUNIOR SUBORDINATED DEBENTURES

     .1.    REDEMPTION. Subject to the Company having received prior approval of
the OTS, if then required under the applicable capital guidelines or policies of
the OTS, the Company may redeem the Junior Subordinated Debentures in accordance
with this Article III.

     .2.    SPECIAL EVENT REDEMPTION. Subject to the Company having received the
prior approval of the OTS, if then required under the applicable capital
guidelines or policies of the OTS, if a Special Event has occurred and is
continuing, then, notwithstanding Section 3.03, the Company shall have the right
upon not less than 30 days' nor more than 60 days' notice to the Holders of the
Junior Subordinated Debentures to redeem the Junior Subordinated Debentures, in
whole but not in part, for cash within 90 days following the occurrence of such
Special Event (the "90-Day Period") at 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 Junior Subordinated
Debentures while the Trust is pursuing any Ministerial Action to eliminate the
Tax Event. The Redemption Price shall be paid prior to 2:00 p.m., Bloomfield
Hills, Michigan, 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 12:00 noon, Bloomfield
Hills, Michigan, time, on the date such Redemption Price is to be paid.



                                       14

<PAGE>   17

     .3.    OPTIONAL REDEMPTION BY COMPANY.

               (a)   Except as otherwise may be specified in this Indenture, the
     Company shall have the right to redeem the Junior Subordinated Debentures,
     in whole or in part, from time to time, on or after March __, 2004, at the
     Redemption Price. Any redemption pursuant to this Section 3.03 will be made
     upon not less than 30 days' nor more than 60 days' notice to the Holders of
     the Junior Subordinated Debentures, at the Redemption Price. If the Junior
     Subordinated Debentures are only partially redeemed pursuant to this
     Section 3.03, the Junior Subordinated 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 Junior Subordinated Debentures are registered
     as a Global Subordinated Debenture, the Depositary shall determine, in
     accordance with its procedures, the principal amount of such Junior
     Subordinated Debentures held by each Holder of Junior Subordinated
     Debentures to be redeemed. The Redemption Price shall be paid prior to 2:00
     p.m., Bloomfield Hills, Michigan 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 Redemption Price
     by 12:00 noon, Bloomfield Hills, Michigan time, on the date such Redemption
     Price is to be paid.

               (b)  If a partial redemption of the Junior Subordinated 
     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 may then
     be listed, if any, the Company shall not be permitted to effect such
     partial redemption and may only redeem the Junior Subordinated Debentures
     in whole or in part to such extent as would not cause such delisting.

     .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 Junior Subordinated
     Debentures 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 Junior Subordinated Debentures 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 to such
     Holders at their last addresses as they shall appear upon the Securities
     Register. 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 Junior Subordinated Debenture 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
     Junior Subordinated Debentures. In the case of any redemption of Junior
     Subordinated Debentures prior to the expiration of any restriction on such
     redemption provided 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, and shall state that payment of the
     Redemption Price of such Junior 


                                       15

<PAGE>   18

     Subordinated Debentures to be redeemed will be made at the office or agency
     of the Company in Bloomfield Hills, Michigan, upon presentation and
     surrender of such Junior Subordinated 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. If less than
     all the Junior Subordinated Debentures are to be redeemed, the notice to
     the Holders of Junior Subordinated Debentures to be redeemed in whole or in
     part shall specify the particular Junior Subordinated Debentures to be so
     redeemed. In case any Junior Subordinated Debenture is to be redeemed in
     part only, the notice that relates to such Junior Subordinated Debenture
     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
     Junior Subordinated Debenture, a new Junior Subordinated Debenture or
     Junior Subordinated Debentures in principal amount equal to the unredeemed
     portion thereof shall be issued to the Holder.

               (b) If less than all the Junior Subordinated Debentures 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 Junior Subordinated Debentures 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 ______dollars U.S. ($_____) or
     any integral multiple thereof), the Junior Subordinated Debentures to be
     redeemed and shall thereafter promptly notify the Company in writing of the
     numbers of the Junior Subordinated 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 Chief Executive Officer, its President
or any Vice President, instruct the Trustee or any paying agent to call all or
any part of the Junior Subordinated Debentures 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 in the name of the Trustee or the paying agent, 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 Securities 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.

     .5.    PAYMENT UPON REDEMPTION.

               (a) If the giving of notice of redemption shall have been 
     completed as above provided, the Junior Subordinated Debentures or portions
     of Junior Subordinated Debentures 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 Redemption Price (which includes interest accrued to the date
     fixed for redemption) and interest on such Junior Subordinated Debentures
     or 


                                       16

<PAGE>   19

     portions of Junior Subordinated 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 with respect to any such Junior
     Subordinated Debentures or portions thereof. On presentation and surrender
     of such Junior Subordinated Debentures on or after the date fixed for
     redemption at the place of payment specified in the notice, such Junior
     Subordinated Debentures shall be paid and redeemed at the Redemption Price
     (which includes the 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 2.05(a)).

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

     .6.    NO SINKING FUND. The Junior Subordinated Debentures are not 
entitled to the benefit of any sinking fund.

                                   ARTICLE IV

                      EXTENSION OF INTEREST PAYMENT PERIOD

     .1.    EXTENSION OF INTEREST PAYMENT PERIOD. So long as no Event of Default
has occurred and is continuing, the Company shall have the right, at any time
and from time to time during the term of the Junior Subordinated Debentures, to
defer payments of interest by extending the interest payment period of such
Junior Subordinated 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 4.01, 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 Junior Subordinated Debentures,
including any Additional Sums and Compounded Interest (together, "Deferred
Interest") that shall be payable to the Holders of the Junior Subordinated
Debentures in whose names the Junior Subordinated Debentures are registered in
the Securities Register on the record date for the Interest Payment Date
coinciding with 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. 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.

Subordinated Debentures at the time and place and in the manner provided herein

<PAGE>   21

to such office or agency until the Company shall, by written notice signed by
its Chief Executive Officer, 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 Trustee with the address thereof, such
presentations, notices and demands may 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.

     .3.    PAYING AGENTS.

               (a)  If the Company shall appoint one or more paying agents for 
     the Junior Subordinated Debentures, 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 or interest on the Junior
               Subordinated Debentures (whether such sums have been paid to it
               by the Company or by any other obligor) 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) to make any payment of the
               principal of or interest on the Junior Subordinated Debentures
               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)(ii) 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 the Junior Subordinated Debentures, it will on or before each
     due date of the principal of or interest on Junior Subordinated Debentures,
     set aside, segregate and hold in trust for the benefit of the Persons
     entitled thereto a sum sufficient to pay such principal or interest so
     becoming due 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) to take such action.
     Whenever the Company shall have one or more paying agents for the Junior
     Subordinated Debentures, it will, prior to each due date of the principal
     of or interest on the Junior Subordinated Debentures, deposit with the
     paying agent a sum sufficient to pay the principal or interest so becoming
     due, such sum to be held in trust for the benefit of the Persons entitled
     to such principal 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.

<PAGE>   22




               (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 13.05, 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 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.

     .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.

     .5.    COMPLIANCE WITH CONSOLIDATION PROVISIONS. The Company will not, 
while any of the Junior Subordinated Debentures 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 XII hereof are complied with.

     .6.    RESTRICTIONS ON CERTAIN PAYMENTS. If at any time (a) there shall 
have occurred any event of which the Company has actual knowledge that (i) with
the giving of notice or the lapse of time, or both, would constitute an Event of
Default and (ii) in respect to which the Company shall not have taken reasonable
steps to cure, or (b) the Company shall have given notice of its election of an
Extended Interest Payment Period as provided herein with respect to the Junior
Subordinated Debentures and shall not have rescinded such notice, or such
Extended Interest Payment Period, or any extension thereof, shall be continuing;
or (c) while the Junior Subordinated Debentures are held by the Trust, the
Company shall be in default with respect to its payment of any obligation under
the Preferred Securities Guarantee, then the Company will not (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 the Junior
Subordinated Debentures) that rank pari passu with or junior in interest to the
Junior 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 Junior
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 Preferred Securities Guarantee and (D) purchases of
common stock related to the issuance of common stock or rights under any of the
Company's benefit plans for its directors, officers or employees).

     .7.    COVENANTS AS TO THE TRUST. For so long as the Trust Securities of
the Trust remain outstanding, the Company will (a) maintain 100% direct or
indirect ownership of the Common Securities of the Trust; provided, however,
that any permitted successor of the Company under this Indenture may succeed to
the Company's ownership of the Common Securities, (b) use its 

                                       20

<PAGE>   23


reasonable efforts to cause the Trust (i) to remain a business trust, except in
connection with a distribution of Junior Subordinated Debentures, the redemption
of all of the Trust Securities of the Trust or certain mergers, consolidations
or amalgamations, each as permitted by the Trust Agreement, and (ii) to
otherwise continue not to be treated as an association taxable as a corporation
or partnership for United States federal income tax purposes and (c) to use its
reasonable efforts to cause each Holder of Trust Securities to be treated as
owning an individual undivided beneficial interest in the Junior Subordinated
Debentures.

     If the Junior Subordinated Debentures are to be issued as a Global
Subordinated Debenture in connection with the distribution of the Junior
Subordinated Debentures to the holders of the Preferred Securities issued by the
Trust upon a Dissolution Event, the Company will use its best efforts to list
such Junior Subordinated Debentures on the NASDAQ National Market or on such
other exchange as the Preferred Securities may then be listed.

               (a)  The Trustee shall preserve, in as current a form as is 
     reasonably practicable, all information as to the names and addresses of

     in Section 6.01 and as to the names and addresses of Holders received by
     the Trustee in its capacity as Securities Registrar (if acting in such
     capacity).

               (b)  The Trustee may destroy any list furnished to it as provided
     in Section 6.01 upon receipt of a new list so furnished.

               (c)  Securityholders may communicate as provided in Section

                           REMEDIES OF THE TRUSTEE AND
                       SECURITYHOLDERS ON EVENT OF DEFAULT

     .1.    EVENTS OF DEFAULT.

               (a)  Whenever used herein, "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 Junior Subordinated Debentures, as
               and when the same shall become due and payable, and continuance
               of such default for a period of 30 days; provided, however, that
               a valid extension of an interest payment period by the Company in
               accordance with the terms of this Indenture shall not constitute
               a default in the payment of interest for this purpose;

                    (ii) the Company defaults in the payment of the principal of
               any of the Junior Subordinated Debentures as and when the same
               shall become due and payable whether at maturity, upon
               redemption, by declaration or otherwise;

                    (iii) the Company fails to observe or perform any other of
               its covenants or agreements hereunder with respect to the Junior
               Subordinated Debentures 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
               Junior Subordinated Debentures at the time Outstanding;

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

                    (v) a court of competent jurisdiction enters an order under
               any Bankruptcy Law that (A) is for relief against the Company in
               an involuntary case, (B) appoints a custodian of the Company for
               all or substantially all of its property, or (C) orders the
               liquidation of the Company, and the order or decree remains
               unstayed and in effect for 90 days; or

                    (vi) in the event Junior Subordinated Debentures are issued
               to the Trust or a trustee of the Trust in connection with the
               issuance of Trust Securities by the Trust, the Trust shall have
               voluntarily or involuntarily dissolved, wound up its business or
               otherwise terminated its existence, except in connection with (A)
               the distribution of Junior Subordinated Debentures to holders of
               Trust Securities in 

                                       23

<PAGE>   26
               liquidation of their interests in the Trust, (B) the redemption
               of all of the outstanding Trust Securities of the Trust or (C)
               certain mergers, consolidations or amalgamations, each as
               permitted by the Trust Agreement.

               (b)  In each and every such case, unless the principal of all the
     Junior Subordinated Debentures shall have already become due and payable,
     either the Trustee or the Holders of not less than 25% in aggregate
     principal amount of the Junior Subordinated Debentures 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 Junior
     Subordinated Debentures 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
     Junior Subordinated Debentures to the contrary.

               (c)  At any time after the principal of the Junior Subordinated
     Debentures 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 Junior Subordinated Debentures then
     Outstanding, 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 Junior Subordinated Debentures and
     the principal of any and all Junior Subordinated Debentures that shall have
     become due otherwise than by acceleration (with interest upon such
     principal 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 Junior Subordinated Debentures to the date of such
     payment or deposit) and the amount payable to the Trustee under Section
     9.06, and (ii) any and all Events of Default under this Indenture, other
     than the nonpayment of principal on Junior Subordinated Debentures that
     shall not have become due by their terms, shall have been remedied or
     waived as provided in Section 7.06. Should the Holders fail to annul such
     declaration and waive such default, then the holders of a majority in
     aggregate Liquidation Amount of the Preferred Securities shall have such
     right.

               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 Junior Subordinated Debentures 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.

     .2.    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

               (a) The Company covenants that (i) in case it shall default in 
     the payment of any installment of interest on any of the Junior
     Subordinated Debentures 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 (ii) in case it shall default in the payment of the principal of
     any of the Junior Subordinated Debentures when the same shall have become
     due and payable, whether upon maturity of the Junior Subordinated
     Debentures or upon redemption or upon declaration or otherwise, then, upon
     demand of the Trustee, the Company will pay to the Trustee, for the benefit
     of the Holders of the Junior Subordinated Debentures, the whole amount that
     then shall have become due and payable on all such Junior Subordinated
     Debentures for principal or interest, or both, as the case may be, with
     interest upon the overdue principal and (to the extent that payment of such
     interest is enforceable under applicable law and, if the Junior
     Subordinated Debentures are held by the Trust or a trustee of the Trust,
     without duplication of any other amounts paid by the Trust or trustee in
     respect thereof) upon overdue installments of interest at the rate per
     annum expressed in the Junior Subordinated Debentures; 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
     9.06.

               (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 Junior Subordinated Debentures 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 Junior
     Subordinated Debentures, wherever situated.

               (c) In case of any receivership, insolvency, liquidation,
     bankruptcy, reorganization, readjustment, arrangement, composition or
     judicial proceedings affecting 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
     Junior Subordinated Debentures allowed for the entire amount due and
     payable by the Company under this 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 9.06; and any receiver, assignee or trustee in
     bankruptcy or reorganization is hereby authorized by each of the Holders to
     make such payments to the Trustee, and, in the event that the Trustee shall
     consent to the making of such payments directly to such Securityholders, to
     pay to the Trustee any amount due it under Section 9.06.



                                       25

<PAGE>   28

               (d) All rights of action and of asserting claims under this 
     Indenture may be enforced by the Trustee without the possession of any of
     the Junior Subordinated Debentures, 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 9.06, be for the
     ratable benefit of the Holders of the Junior Subordinated Debentures.

     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 this 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
Junior Subordinated Debentures 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.

     .3.    APPLICATION OF MONEYS COLLECTED. Any moneys collected by the Trustee
pursuant to this Article with respect to the Junior Subordinated Debentures
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 interest, upon presentation of the Junior Subordinated Debentures, 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 9.06;

               SECOND, to the payment of all Senior and Subordinated Debt of the
     Company if and to the extent required by Article XVI; and

               THIRD, to the payment of the amounts then due and unpaid upon 
     Junior Subordinated Debentures for principal 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 Junior Subordinated Debentures for principal and
     interest, respectively.

     .4.    LIMITATION ON SUITS. No Holder shall have any right by virtue of or
by availing 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 (a) such Holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof; (b) the
Holders of not less than 25% in aggregate principal amount of the Junior
Subordinated Debentures then Outstanding shall have 


                                       26


<PAGE>   29

made written request upon the Trustee to institute such action, suit or
proceeding in its own name as trustee hereunder; (c) 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 (d) 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 (e) during such 60-day period, the Holders of a majority in
principal amount of the Junior Subordinated Debentures do not give the Trustee a
direction inconsistent with the request.

     Notwithstanding any other provisions of this Indenture to the contrary, the
right of any Holder to receive payment of the principal of and interest on the
Junior Subordinated Debentures on or after the respective due dates (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 Junior Subordinated Debenture hereunder it is expressly
understood, intended and covenanted by the Holder thereof with every other such
Holder and the Trustee, that no one or more Holders shall have any right in any
manner whatsoever by virtue of or by availing any provision of this Indenture to
affect, disturb or prejudice the rights of any other Holders, or to obtain or
seek to obtain priority over or preference to any such other Holders, 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 Junior Subordinated
Debentures. 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.

     .5.    RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER.

               (a) Except as otherwise provided in Section 7.02, 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 Junior Subordinated Debentures, 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 Junior Subordinated Debentures.

               (b) No delay or omission of the Trustee or of any Holder of any 
     of the Junior Subordinated Debentures to exercise any right or power
     accruing upon any Event of Default occurring and continuing 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 7.04, 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.

     .6.    CONTROL BY SECURITYHOLDERS. The Holders of a majority in aggregate
principal amount of the Junior Subordinated Debentures at the time Outstanding,
determined in accordance with Section 10.04, 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;
provided, however, that such direction shall not be in conflict with any rule of
law or 


                                       27

<PAGE>   30


with this Indenture. Subject to the provisions of Section 9.01, 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 Junior Subordinated Debentures at the time Outstanding affected thereby,
determined in accordance with Section 10.04, may on behalf of the Holders of all
of the Junior Subordinated Debentures waive any past default in the performance
of any of the covenants contained herein and its consequences, except (a) a
default in the payment of the principal of or interest on any of the Junior
Subordinated Debentures as and when the same shall become due by its terms
otherwise than by acceleration (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal has been
deposited with the Trustee in accordance with Section 7.01(c)), (b) a default in
the covenants contained in Section 5.06 or (c) in respect of a covenant or
provision hereof which under Article XI cannot be modified or amended without
the consent of the Holder of each Outstanding Junior Subordinated Debenture
affected; provided, however, that if the Junior Subordinated Debentures are held
by the Trust or a Trustee of the Trust, such waiver or modification to such
waiver shall not be effective until the Holders of a majority in Liquidation
Amount of Trust Securities of the Trust shall have consented to such waiver or
modification to such waiver; provided further, that if the consent of the Holder
of each Outstanding Junior Subordinated Debenture is required, such waiver shall
not be effective until each Holder of the Trust Securities of the Trust 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 Junior Subordinated Debentures 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.

     .7.    UNDERTAKING TO PAY COSTS. All parties to this Indenture agree, and 
each Holder of any Junior Subordinated Debentures by such Holder's acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the 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 Junior Subordinated
Debentures, or to any suit instituted by any Securityholder for the enforcement
of the payment of the principal of or interest on the Junior Subordinated
Debentures on or after the due dates thereof.

<PAGE>   31


the forms contained as Exhibit A to this Indenture, attached hereto and
incorporated herein by reference.

     .2.    ORIGINAL ISSUE OF JUNIOR SUBORDINATED DEBENTURES. Junior 
Subordinated Debentures in the aggregate principal amount of $__________ may,

Company, signed by its Chairman, its Vice Chairman, its Chief Executive Officer,
its President or any Vice President, without any further action by the Company.

                                   ARTICLE IX

                             CONCERNING THE TRUSTEE

     .1.    CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

               (a)  The Trustee, prior to the occurrence of an Event of Default 
     and after the curing of all Events of Default that may have occurred, shall
     undertake to perform with respect to the Junior Subordinated Debentures
     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 has occurred (that has not
     been cured or waived), the Trustee shall exercise 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.

               (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:

                    (i)  prior to the occurrence of an Event of Default and 
               after the curing or waiving of all such Events of Default that
               may have occurred:

                         (A)  the duties and obligations of the Trustee shall be
                    determined solely by the express provisions of this
                    Indenture, and the Trustee shall not be liable 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

                         (B)  in the absence of bad faith on the part of the 
                    Trustee, the Trustee may 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 




                                       29

<PAGE>   32

                    determine whether or not they conform to the requirement of
                    this Indenture;

                    (ii) 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;

                    (iii) 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 Junior Subordinated
               Debentures 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; and

                    (iv) 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.

     .2.    CERTAIN RIGHTS OF TRUSTEE. Except as otherwise provided in Section
9.01:

               (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 Chief Executive
     Officer, the President or any Vice President and by the Secretary or an
     Assistant Secretary or the Chief Accounting Officer 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 (that has not been cured or waived) to
     exercise 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 


                                       30

<PAGE>   33

     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 Junior Subordinated Debentures (determined as provided in
     Section 10.04); 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 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.

     .3.    TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF THE JUNIOR
SUBORDINATED DEBENTURES.

               (a)  The recitals contained herein and in the Junior 
     Subordinated Debentures 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 Junior Subordinated Debentures.

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

     .4.    MAY HOLD JUNIOR SUBORDINATED DEBENTURES. The Trustee or any paying
agent or Securities Registrar, in its individual or any other capacity, may
become the owner or pledgee of Junior Subordinated Debentures with the same
rights it would have if it were not Trustee, paying agent or Securities
Registrar.



                                       31
<PAGE>   34


     .5.    MONEYS HELD IN TRUST. Subject to the provisions of Section 13.05,
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.

     .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 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 Junior Subordinated Debentures 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 the Junior Subordinated Debentures.

     .7.    RELIANCE ON OFFICERS' CERTIFICATE. Except as otherwise provided in
Section 9.01, 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.

     .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 


                                       32

<PAGE>   35

and the Company shall in all respects comply with the provisions of 
Section 310(b) of the Trust Indenture Act.

     .9.    CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. There shall at all times be
a Trustee with respect to the Junior Subordinated Debentures 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 $500,000 (and
its parent holding company having a combined capital and surplus of at least
$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 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. No Affiliate of the Company may 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 9.10.

     .10.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

               (a)  The Trustee, or any successor hereafter appointed, may at 
     any time resign by giving written notice thereof to the Company and by
     transmitting notice of resignation by mail, first class postage prepaid, to
     the Securityholders, as their names and addresses appear upon the
     Securities Register. Upon receiving such notice of resignation, the Company
     shall promptly 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 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, or any
     Securityholder who has been a bona fide Holder of Junior Subordinated
     Debentures for at least six months may, subject to the provisions of
     Section 7.07, on behalf of such Securityholder and all other Holders,
     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
               Section 9.08 after written request therefor by the Company or by
               any Securityholder who has been a bona fide Holder of Junior
               Subordinated Debentures for at least six months; or

                    (ii) the Trustee shall cease to be eligible in accordance
               with the provisions of Section 9.09 and shall fail to resign
               after written request therefor by the Company or by any such
               Securityholder; or

                                       33

<PAGE>   36


                    (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 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 removed and one copy to the successor trustee,
     or, subject to the provisions of Section 7.07, unless the Trustee's duty to
     resign is stayed as provided herein, any Securityholder who has been a bona
     fide Holder of Junior Subordinated Debentures for at least six months may,
     on behalf of that Holder and all other Holders, 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 Junior Subordinated Debentures at the time Outstanding may at any time
     remove the Trustee by so notifying the Trustee and the Company and may
     appoint a successor Trustee with the consent of the Company.

               (d)  Any resignation or removal of the Trustee and appointment of
     a successor trustee 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.

     .11.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

               (a) In case of the appointment hereunder of a successor trustee,
     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)  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) of this Section.

               (c)  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.


                                       34

<PAGE>   37

               (d)  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
     Securities 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.

     .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
qualified and eligible under the provisions of this Article IX, 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
Junior Subordinated Debentures 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 Junior Subordinated Debentures so authenticated with the same effect
as if such successor Trustee had itself authenticated such Junior Subordinated
Debentures.

     .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.

     .14.   APPOINTMENT OF AUTHENTICATING AGENT. At any time when any of the
Junior Subordinated Debentures remain Outstanding, the Trustee may appoint an
Authenticating Agent or Agents which shall be authorized to act on behalf of the
Trustee to authenticate Junior Subordinated Debentures issued upon original
issuance, exchange, registration of transfer or partial redemption thereof or
pursuant to Section 2.08, and Junior Subordinated Debentures so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery
of Junior Subordinated Debentures by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any state thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $500,000 (and its parent holding company having a
combined capital and surplus of at least $50,000,000) and subject to supervision
or examination by federal or state authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of such supervision or examining authority, for the purposes of
this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition


                                       35

<PAGE>   38


so published. If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this
Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such notice of
resignation or upon such termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this
Section, the Trustee may appoint a successor Authenticating Agent which shall be
acceptable to the Company and shall mail written notice of such appointment by
first class mail, postage prepaid, to all Securityholders as their names and
addresses appear in the Securities Register. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with the like effect as
if originally named as an Authenticating Agent herein. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 9.06.

     If an appointment is made pursuant to this Section, the Junior Subordinated
Debentures may have endorsed thereon, in lieu of the form of certificate of
authentication set forth in Section 8.01, a certificate of authentication in the
following form:

     "This is one of the Junior Subordinated Debentures described in the within
mentioned Indenture."

                                   ------------------------------------------,
                                   as Trustee

                                   ARTICLE X

                         CONCERNING THE SECURITYHOLDERS

     .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 Junior Subordinated Debentures 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
have joined therein may be evidenced by any instrument or any number of
instruments of similar tenor executed by such Holders in Person or by agent or
proxy appointed in writing.

     If the Company shall solicit from the Securityholders 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 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 Junior Subordinated
Debentures have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other action, and for that
purpose the Outstanding Junior Subordinated Debentures 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.

     .2.    PROOF OF EXECUTION BY SECURITYHOLDERS. Subject to the provisions of
Section 6.01, 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 Junior Subordinated Debentures 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 Junior Subordinated Debentures shall be
     proved by the Securities Register or by a certificate of the Securities
     Registrar thereof.

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

     .3.    WHO MAY BE DEEMED OWNERS. Prior to the due presentment for 
registration of transfer of any Junior Subordinated Debenture, the Company, the
Trustee, any paying agent and 


                                       37

<PAGE>   40


any Securities Registrar may deem and treat the Person in whose name such Junior
Subordinated Debenture shall be registered upon the books of the Company as the
absolute owner of such Junior Subordinated Debenture (whether or not such Junior
Subordinated Debenture shall be overdue and notwithstanding any notice of
ownership or writing thereon made by anyone other than the Securities Registrar)
for the purpose of receiving payment of or on account of the principal of and
(subject to Section 2.03) interest on such Junior Subordinated Debenture and for
all other purposes; and neither the Company nor the Trustee nor any paying agent
nor any Securities Registrar shall be affected by any notice to the contrary.

     .4.    CERTAIN JUNIOR SUBORDINATED DEBENTURES OWNED BY COMPANY DISREGARDED.
In determining whether the Holders of the requisite aggregate principal amount
of Junior Subordinated Debentures have concurred in any direction, consent or
waiver under this Indenture, the Junior Subordinated Debentures that are owned
by the Company or any other obligor on the Junior Subordinated Debentures or by
any Person directly or indirectly controlling or controlled by or under common
control with the Company or any other obligor on the Junior Subordinated
Debentures 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 Junior Subordinated Debentures that the Trustee actually knows are
so owned shall be so disregarded. The Junior Subordinated Debentures 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 with respect to such Junior Subordinated
Debentures 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.

     .5.    ACTIONS BINDING ON FUTURE SECURITYHOLDERS. At any time prior to 
(but not after) the evidencing to the Trustee, as provided in Section 10.01, of
the taking of any action by the Holders of the majority or percentage in
aggregate principal amount of the Junior Subordinated Debentures specified in
this Indenture in connection with such action, any Holder who is shown by the
evidence to have consented to such action may, by filing written notice with the
Trustee, and upon proof of holding as provided in Section 10.02, revoke such
action so far as concerns such Holder's Junior Subordinated Debentures. Except
as aforesaid any such action taken by the Holder shall be conclusive and binding
upon such Holder and upon all future Holders and owners of such Holder's Junior
Subordinated Debentures, and of any Junior Subordinated Debentures 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
Junior Subordinated Debentures. Any action taken by the Holders of the majority
or percentage in aggregate principal amount of the Junior Subordinated
Debentures specified in this Indenture in connection with such action shall be
conclusively binding upon the Company, the Trustee and the Holders of all the
Junior Subordinated Debentures.

                                   ARTICLE XI

                             SUPPLEMENTAL INDENTURES

     .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, or 
     in the Junior Subordinated Debentures, provided that any such action does
     not materially adversely affect the interests of the Holders or the holders
     of the Preferred Securities so long as they remain outstanding;

            (b)  to comply with Article XII;

            (c)  to provide for uncertificated Junior Subordinated Debentures
     in addition to or in place of certificated Junior Subordinated Debentures;

            (d)  to add to the covenants of the Company for the benefit of 
     the Holders 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 Junior Subordinated Debentures,
     as herein set forth;

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

            (g)  to establish the form of any certifications required to be 
     furnished pursuant to the terms of this Indenture or to add to the rights
     of the Holders.

     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 Junior Subordinated Debentures at the time Outstanding,
notwithstanding any of the provisions of Section 11.02.

     .2.    SUPPLEMENTAL INDENTURES WITH CONSENT OF SECURITYHOLDERS. With the
consent (evidenced as provided in Section 10.01) of the Holders of not less than
a majority in aggregate principal amount of the Junior Subordinated Debentures
at the time Outstanding, the Company, 


                                       39

<PAGE>   42

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 11.01 the rights
of the Holders of the Junior Subordinated Debentures under this Indenture;
provided, however, that no such supplemental indenture shall without the consent
of the Holders of each Junior Subordinated Debenture then Outstanding, (a)
change (except as expressly provided herein pursuant to Section 2.02) the stated
maturity of the Junior Subordinated Debentures or reduce the principal amount
thereof; or reduce the rate or extend (except as expressly provided herein
pursuant to Section 4.01) the time of payment of interest thereon; or (b) reduce
the percentage of principal amount of Junior Subordinated Debentures, the
Holders of which are required to consent to any such supplemental indenture;
provided, further, that if the Junior Subordinated Debentures are held by the
Trust or a trustee of the Trust, such supplemental indenture shall not be
effective until the holders of a majority in aggregate Liquidation Amount of
Preferred Securities shall have consented to such supplemental indenture;
provided further, that if the consent of the Holder of each Outstanding Junior
Subordinated Debenture is required, such supplemental indenture shall not be
effective until each Holder of the Trust Securities shall have consented to such
supplemental indenture.

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

     .3.    EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article or of Section
12.01, this Indenture shall be and be deemed to be modified and amended in
accordance therewith.

     .4.    JUNIOR SUBORDINATED DEBENTURES AFFECTED BY SUPPLEMENTAL INDENTURES.
Junior Subordinated Debentures, 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 12.01, may bear a
notation in form approved by the Company, as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Junior
Subordinated Debentures so modified as to conform, in the opinion of the Board
of Directors, 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 Junior Subordinated Debentures then
Outstanding.

     .5.    EXECUTION OF SUPPLEMENTAL INDENTURES. Upon the request of the
Company, accompanied by 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 9.01, may receive
an Opinion of Counsel as conclusive


                                       40

<PAGE
<PAGE>   43

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 as their names and addresses appear upon the Securities
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.

                                  ARTICLE XII

                              SUCCESSOR CORPORATION

         .1. COMPANY MAY CONSOLIDATE, ETC. 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 (a) 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 Junior Subordinated Debentures issued under
this Indenture; (b) immediately after giving effect thereto, no Event of
Default, and no event which, after notice or lapse of time or both, would become
an Event of Default, shall have occurred and be continuing; and (c) such
successor Person expressly assumes the due and punctual performance and
observance of all the covenants and conditions of this Indenture to be kept and
performed by the Company by executing and delivering a supplemental indenture in
form and substance satisfactory to the Trustee.

         .2. SUCCESSOR SUBSTITUTED.

              (a) In case of any such consolidation, merger, sale, conveyance,
         transfer or other disposition and upon the assumption by the successor
         Person by supplemental indenture, executed and delivered to the Trustee
         and satisfactory in form to the Trustee, of the due and punctual
         payment of the principal of and interest on all of the Junior
         Subordinated Debentures Outstanding and the due and punctual
         performance of all of the covenants and conditions of this Indenture to
         be performed by the Company, such successor Person shall succeed to and
         be substituted for the Company, with the same effect as if it had been
         named as the Company herein, and thereupon the predecessor corporation
         shall be relieved of all obligations and covenants under this Indenture
         and the Junior Subordinated Debentures.

              (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 Junior Subordinated Debentures
         thereafter to be issued as may be appropriate.

         .3. EVIDENCE OF CONSOLIDATION, ETC., TO TRUSTEE. The Trustee, subject
to the provisions of Section 9.01, 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.

                                  ARTICLE XIII

                           SATISFACTION AND DISCHARGE

         .1. SATISFACTION AND DISCHARGE OF INDENTURE. If at any time: (a) the
Company shall have delivered to the Trustee for cancellation all Junior
Subordinated Debentures theretofore authenticated (other than any Junior
Subordinated Debentures that shall have been destroyed, lost or stolen and that
shall have been replaced or paid as provided in Section 2.08) and Junior
Subordinated Debentures for 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 13.05); or (b) all such Junior Subordinated Debentures not
theretofore delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for 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 be deposited with the Trustee as trust funds the entire
amount in moneys or 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 Junior Subordinated
Debentures not theretofore delivered to the Trustee for cancellation, including
principal 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 by the Company; then this
Indenture shall thereupon cease to be of further effect except for the
provisions of Sections 2.02, 2.03, 2.04, 2.05, 4.01, 4.02, 4.03 and 9.10, that
shall survive until the date of maturity or redemption date, as the case may be,
and Sections 9.06 and 13.05, 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.

         .2. DISCHARGE OF OBLIGATIONS. If at any time all such Junior
Subordinated Debentures not theretofore delivered to the Trustee for
cancellation or that have not become due and payable as described in Section
13.01 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 Junior Subordinated
Debentures not theretofore delivered to the Trustee for cancellation, including
principal 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 by the Company, 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 shall cease
to be of further effect except for the provisions of Sections 2.02, 2.03, 2.04,
2.05, 4.01, 4.02, 4.03, 9.06, 9.10 and 13.05 hereof that




                                       42
<PAGE>   45

shall survive until such Junior Subordinated Debentures shall mature and be
paid. Thereafter, Sections 9.06 and 13.05 shall survive.

         .3. DEPOSITED MONEYS TO BE HELD IN TRUST. All moneys or Governmental
Obligations deposited with the Trustee pursuant to Sections 13.01 or 13.02 shall
be held in trust and shall be available for payment as due, either directly or
through any paying agent (including the Company acting as its own paying agent),
to the Holders of the Junior Subordinated Debentures for the payment or
redemption of which such moneys or Governmental Obligations have been deposited
with the Trustee.

         .4. PAYMENT OF MONEYS 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 provisions of this Indenture
shall, upon demand of the Company, be paid to the Trustee and thereupon such
paying agent shall be released from all further liability with respect to such
moneys or Governmental Obligations.

         .5. REPAYMENT TO COMPANY. Any moneys or Governmental Obligations
deposited with any paying agent or the Trustee, or then held by the Company in
trust for payment of principal of or interest on the Junior Subordinated
Debentures that are not applied but remain unclaimed by the Holders of such
Junior Subordinated Debentures for at least two years after the date upon which
the principal of or interest on such Junior Subordinated Debentures shall have
respectively become due and payable, shall be repaid to the Company on the
second annual anniversary of when such payment was originally due 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
Junior Subordinated Debentures entitled to receive such payment shall
thereafter, as an unsecured general creditor, look only to the Company for the
payment thereof.

                                  ARTICLE XIV

                           IMMUNITY OF INCORPORATORS,
                      STOCKHOLDERS, OFFICERS AND DIRECTORS

         .1. NO RECOURSE. No recourse under or upon any obligation, covenant or
agreement of this Indenture, or of any Junior Subordinated Debenture, or for any
claim based thereon or otherwise in respect thereof, shall be had against any
incorporator, stockholder, officer or director as such, past, present or future,
of the Company or of any predecessor or successor corporation, either directly
or through the Company or any such 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; it being expressly understood that this
Indenture and the obligations issued hereunder are solely corporate obligations,
and that no such personal liability whatever shall attach to, or is or shall be
incurred by, the incorporators, stockholders, officers or directors as such, of
the Company or of any predecessor or successor corporation, or any of them,
because of the creation of the indebtedness hereby authorized, or under or by
reason of the obligations, covenants or agreements contained in this Indenture
or in any of the Junior Subordinated Debentures or implied therefrom; and that
any and all such personal liability of






                                       43
<PAGE>   46

every name and nature, either at common law or in equity or by constitution or
statute, of, and any and all such rights and claims against, every such
incorporator, stockholder, officer or director as such, because of the creation
of the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Indenture or in any of the Junior
Subordinated Debentures or implied therefrom, are hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Junior Subordinated Debentures.

                                   ARTICLE XV

                            MISCELLANEOUS PROVISIONS

         .1. EFFECT ON SUCCESSORS AND ASSIGNS. All the covenants, stipulations,
promises and agreements in this Indenture contained by or on behalf of the
Company or the Trustee shall bind their respective successors and assigns,
whether so expressed or not.

         .2. ACTIONS BY SUCCESSOR. Any act or proceeding by any provision of
this Indenture authorized or required to be done or performed by any board,
committee or officer of the Company shall and may be done and performed with
like force and effect by the corresponding board, committee or officer of any
corporation that shall at the time be the lawful sole successor of the Company.

         .3. SURRENDER OF COMPANY POWERS. The Company by instrument in writing
executed by authority of two-thirds of its Board of Directors and delivered to
the Trustee may surrender any of the powers reserved to the Company, and
thereupon such power so surrendered shall terminate both as to the Company and
as to any successor corporation.

         .4. NOTICES. Except as otherwise expressly provided herein any notice
or demand that by any provision of this Indenture is required or permitted to be
given or served by the Trustee or by the Holders of Junior Subordinated
Debentures to or on the Company may be given or served by being deposited first
class postage prepaid in a post-office letterbox addressed (until another
address is filed in writing by the Company with the Trustee), as follows: c/o
Flagstar Bancorp, Inc., 2600 Telegraph Road, Bloomfield Hills, Michigan 48302,
Attention: Chief Executive Officer. Any notice, election, request or demand by

been sufficiently given or made, for all purposes, if given or made in writing
at the Corporate Trust Office of the Trustee.

         .5. GOVERNING LAW. This Indenture and each Junior Subordinated
Debenture shall be deemed to be a contract made under the internal laws of the
State of Michigan and for all purposes shall be construed in accordance with the
laws of said state, provided that the immunities and the standard of care of the
Trustee shall be governed by Michigan law.

         .6. TREATMENT OF JUNIOR SUBORDINATED DEBENTURES AS DEBT. It is intended
that the Junior Subordinated Debentures will be treated as indebtedness and not
as equity for federal income tax purposes. The provisions of this Indenture
shall be interpreted to further this intention.






                                       44
<PAGE>   47

         .7. COMPLIANCE CERTIFICATES AND OPINIONS.

              (a) Upon any application or demand by the Company to the Trustee
         to take any action under any of the provisions of this Indenture, the
         Company shall furnish to the Trustee an Officers' Certificate stating
         that all conditions precedent provided for in this Indenture relating
         to the proposed action have been complied with and an Opinion of
         Counsel stating that in the opinion of such counsel all such conditions
         precedent have been complied with, except that in the case of any such
         application or demand as to which the furnishing of such documents is
         specifically required by any provision of this Indenture relating to
         such particular application or demand, no additional certificate or
         opinion need be furnished.

              (b) Every certificate or opinion delivered to the Trustee with
         respect to compliance with a condition or covenant in this Indenture
         shall include (i) a statement that the Person making such certificate
         or opinion has read such covenant or condition; (ii) a brief statement
         as to the nature and scope of the examination or investigation upon
         which the statements or opinions contained in such certificate or
         opinion are based; (iii) a statement that, in the opinion of such
         Person, such Person has made such examination or investigation as is
         necessary to enable such Person to express an informed opinion as to
         whether or not such covenant or condition has been complied with; and
         (iv) a statement as to whether or not, in the opinion of such Person,
         such condition or covenant has been complied with.

         .8. PAYMENTS ON BUSINESS DAYS. In any case where the date of maturity
of interest or principal of the Junior Subordinated Debentures or the date of
redemption of the Junior Subordinated Debentures shall not be a Business Day,
then payment of interest or principal will be made on the next succeeding
Business Day (without any additional 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 the date such
payment was originally payable.

         .9. CONFLICT WITH TRUST INDENTURE ACT. If and to the extent that any
provision of this Indenture limits, qualifies or conflicts with the duties
imposed by Sections 310 to 317, inclusive, of the Trust Indenture Act, such
imposed duties shall control.

         .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.

         .11. SEPARABILITY. In case any one or more of the provisions contained
in this Indenture or in the Junior Subordinated Debentures 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 the Junior Subordinated Debentures, but this Indenture and the
Junior Subordinated Debentures shall be construed as if such invalid or illegal
or unenforceable provision had never been contained herein or therein.







                                       45
<PAGE>   48

         .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 will remain liable for all such obligations.
Subject to the foregoing, this 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 hereto.

         .13. ACKNOWLEDGMENT OF RIGHTS. The Company acknowledges that, with
respect to any Junior Subordinated Debentures held by the Trust or a trustee of
the Trust, if the Property Trustee of the Trust fails to enforce its rights
under this Indenture as the Holder of the Junior Subordinated Debentures held as
the assets of the Trust, 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 Junior Subordinated Debentures 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 Junior Subordinated Debentures having a
principal amount equal to the aggregate Liquidation Amount of the Preferred
Securities of such holder on or after the respective due date specified in the
Junior Subordinated Debentures. This Section 15.13 may not be amended without
the prior written consent of the holders of all of the Preferred Securities.

                                  ARTICLE XVI

                 SUBORDINATION OF JUNIOR SUBORDINATED DEBENTURES

         .1. AGREEMENT TO SUBORDINATE. The Company covenants and agrees, and
each Holder of Junior Subordinated Debentures issued hereunder by such Holder's
acceptance thereof likewise covenants and agrees, that all Junior Subordinated
Debentures shall be issued subject to the provisions of this Article XVI; and
each Holder, 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 and interest on all
Junior Subordinated 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 and Subordinated Debt, 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.

         .2. DEFAULT ON SENIOR AND SUBORDINATED DEBT. 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 and Subordinated Debt
of the Company or in the event that the maturity of any Senior and Subordinated
Debt of the Company has been accelerated because of a 





                                       46
<PAGE>   49

default, then, in either case, no payment shall be made by the Company with
respect to the principal of or interest on the Junior Subordinated 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 16.02, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior and
Subordinated Debt or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior and
Subordinated Debt may have been issued, as their respective interests may
appear, but only to the extent that the holders of the Senior and Subordinated
Debt (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 and Subordinated Debt and only the amounts specified in such
notice to the Trustee shall be paid to the holders of Senior and Subordinated
Debt.

         .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 and Subordinated Debt 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 or
interest on the Junior Subordinated 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 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 or by the Trustee under the Indenture if received by them or it,
directly to the holders of Senior and Subordinated Debt of the Company (pro rata
to such holders on the basis of the respective amounts of Senior and
Subordinated Debt 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 and
Subordinated Debt may have been issued, as their respective interests may
appear, to the extent necessary to pay such Senior and Subordinated Debt 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 and Subordinated Debt,
before any payment or distribution is made to the Holders 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 and Subordinated Debt 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 and Subordinated Debt or
their representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior and
Subordinated Debt may have been issued, and their respective interests may
appear, as calculated by the Company, for application to the payment of





                                       47
<PAGE>   50

all Senior and Subordinated Debt of the Company, as the case may be, remaining
unpaid to the extent necessary to pay such Senior and Subordinated Debt 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 and
Subordinated Debt.

         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 Junior Subordinated Debentures to the payment of all Senior and
Subordinated Debt of the Company, as the case may be, that may at the time be
outstanding, provided that (a) such Senior and Subordinated Debt is assumed by
the new corporation, if any, resulting from any such reorganization or
readjustment, and (b) the rights of the holders of such Senior and Subordinated
Debt are not, without the consent of such holders, altered by such
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 XII of this Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section 16.03 if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article XII of this Indenture. Nothing in Section 16.02 or in this Section
16.03 shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 9.06 of this Indenture.

         .4. SUBROGATION. Subject to the payment in full of all Senior and
Subordinated Debt of the Company, the rights of the Holders of the Junior
Subordinated Debentures shall be subrogated to the rights of the holders of such
Senior and Subordinated Debt to receive payments or distributions of cash,
property or securities of the Company, as the case may be, applicable to such
Senior and Subordinated Debt until the principal of and interest on the Junior
Subordinated Debentures shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of such Senior and
Subordinated Debt of any cash, property or securities to which the Holders of
the Junior Subordinated 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 and Subordinated Debt by Holders of the Junior Subordinated Debentures or
the Trustee, shall, as between the Company, its creditors other than holders of
Senior and Subordinated Debt of the Company, and the Holders of the Junior
Subordinated Debentures, be deemed to be a payment by the Company to or on
account of such Senior and Subordinated Debt. 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 Junior Subordinated
Debentures, on the one hand, and the holders of such Senior and Subordinated
Debt on the other hand.

         Nothing contained in this Article XVI or elsewhere in this Indenture or
in the Junior Subordinated Debentures is intended to or shall impair, as between
the Company, its creditors other than the holders of Senior and Subordinated
Debt of the Company, and the Holders of the Junior Subordinated Debentures, the
obligation of the Company, which is absolute and





                                       48
<PAGE>   51

unconditional, to pay to the Holders of the Junior Subordinated Debentures the
principal of and interest on the Junior Subordinated 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 Junior Subordinated
Debentures and creditors of the Company, other than the holders of Senior and
Subordinated Debt of the Company, nor shall anything herein or therein prevent
the Trustee or the Holder of any Junior Subordinated Debenture from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article XVI of the holders
of such Senior and Subordinated Debt 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 9.01, and
the Holders of the Junior Subordinated 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, agent or other Person making such
payment or distribution, delivered to the Trustee or to the Holders of the
Junior Subordinated Debentures, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior and
Subordinated Debt 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.

         .5. TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder of Junior
Subordinated 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.

         .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 moneys to or by the Trustee in
respect of the Junior Subordinated 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
moneys to or by the Trustee in respect of the Junior Subordinated 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 and Subordinated Debt or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 9.01, 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 16.06 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 interest on any Junior Subordinated 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 it was received, and shall not be affected






                                       49
<PAGE>   52

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 9.01, 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 and Subordinated Debt of
the Company (or a trustee on behalf of such holder), to establish that such
notice has been given by a holder of such Senior and Subordinated Debt 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 and Subordinated Debt 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 and Subordinated
Debt 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 any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

         .7. RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR AND SUBORDINATED DEBT. The
Trustee in its individual capacity shall be entitled to all the rights set forth
in this Article XVI in respect of any Senior and Subordinated Debt at any time
held by it, to the same extent as any other holder of Senior and Subordinated
Debt, and nothing in this Indenture shall deprive the Trustee of any of its
rights as such holder.

         With respect to the holders of Senior and Subordinated Debt 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 XVI, and
no implied covenants or obligations with respect to the holders of such Senior
and Subordinated Debt shall be read into this Indenture against the Trustee. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of such
Senior and Subordinated Debt and, subject to the provisions of Section 9.01, the
Trustee shall not be liable to any holder of such Senior and Subordinated Debt
if it shall pay over or deliver to Holders of Junior Subordinated Debentures,
the Company or any other Person money or assets to which any holder of such

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,

                 (FORM OF FACE OF JUNIOR SUBORDINATED DEBENTURE)


         This Junior Subordinated Debenture is a [Global] Subordinated Debenture
within the meaning of the Indenture hereinafter referred to and is registered in
the name of [______________] [a Depositary or a nominee of a Depositary]. This
Junior Subordinated Debenture is exchangeable for Junior Subordinated Debentures
registered in the name of a person other than [____________] [the Depositary or
its nominee] only in the limited circumstances described in the Indenture, and
no transfer of this Junior Subordinated Debenture [(other than a transfer of
this Junior Subordinated Debenture as a whole by the Depositary to a nominee of
the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary)] may be registered except in such limited
circumstances.

         [Unless this Junior Subordinated Debenture is presented by an
authorized representative of TRUSTEE ( ____[address]_______________) to the
issuer or its agent for registration of transfer, exchange or payment, and any
Junior Subordinated Debenture issued is registered in the name of Cede & Co. or
such other name as requested by an authorized representative of TRUSTEE (and any
payment hereon is made to Cede & Co. or to such other entity as is requested by
an authorized representative of TRUSTEE), ANY TRANSFER, PLEDGE OR OTHER USE
HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch the
registered owner hereof, Cede & Co., has an interest herein.]

                           DUE ________________, 2029

         Flagstar Bancorp, Inc., a Delaware corporation (the "Company," which
term includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to TRUSTEE or registered
assigns, the principal sum of
____________________________________________________________________ Dollars
($__________) on ________________, 2029 (which date may be shortened as provided
in the Indenture, the "Stated Maturity"), and to pay interest on said principal
sum from ________________, 1999, or from the most recent interest payment date
(each such date, an "Interest Payment Date") to which interest has been paid or
duly provided for, quarterly (subject to deferral as set forth herein) in
arrears on the 15th day of March, June, September and December in each year
commencing June 15, 1999, at the rate of ____% per annum until the principal
hereof shall have become due and payable, and on any overdue principal and
(without duplication and to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the
same rate per annum compounded quarterly. The

<PAGE>   57

amount of each interest payment due with respect to the Junior Subordinated
Debentures will include amounts accrued through the date the interest payment is
due. The amount of interest payable on any Interest Payment Date shall 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 this Junior Subordinated Debenture
is not a Business Day (as defined in the Indenture), then payment of 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),
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. The 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 Junior Subordinated Debenture (or one or more Predecessor Junior
Subordinated Debentures, as defined in the 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. The principal of and
the interest on this Junior Subordinated Debenture shall be payable at the
office or agency of the Trustee (as defined in the Indenture) 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 (as defined in the Indenture)
at such address as shall appear in the Securities Register (as defined in the
Indenture). Notwithstanding the foregoing, so long as the Holder of this Junior
Subordinated Debenture is the Property Trustee (as defined in the Indenture),
the payment of the principal of and interest on this Junior Subordinated
Debenture will be made at such place and to such account as may be designated by
the Property Trustee.

         The Stated Maturity may be shortened at any time by the Company to any
date not earlier than ________________, 2004, subject to the Company having
received prior approval of the OTS (as defined in the Indenture) if then
required under applicable capital guidelines or policies of the OTS.

         The indebtedness evidenced by this Junior Subordinated 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 and Subordinated Debt (as defined in
the Indenture), and this Junior Subordinated Debenture is issued subject to the
provisions of the Indenture with respect thereto. Each Holder of this Junior
Subordinated 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 and Subordinated Debt, whether now outstanding or hereafter incurred, and
waives reliance by each such holder upon said provisions.

         This Junior Subordinated Debenture shall not be entitled to any benefit
under the Indenture, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

         The provisions of this Junior Subordinated Debenture are continued on
the reverse side hereof and such continued provisions shall for all purposes
have the same effect as though fully set forth at this place.

         IN WITNESS WHEREOF, the Company has caused this instrument to be
executed.

               [FORM OF REVERSE OF JUNIOR SUBORDINATED DEBENTURE]
                       ____% JUNIOR SUBORDINATED DEBENTURE
                                   (CONTINUED)


         This Junior Subordinated Debenture is one of the junior subordinated
debentures of the Company (herein sometimes referred to as the "Junior
Subordinated Debentures"), specified in the Indenture, all issued under and
pursuant to a Subordinated Indenture dated as of ________________, 1999 (the
"Indenture") duly executed and delivered between the Company and TRUSTEE, 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 Junior
Subordinated Debentures. The Junior Subordinated Debentures are limited in
aggregate principal amount as specified in the Indenture.

         Because of the occurrence and continuation of a Special Event (as
defined in the Indenture), in certain circumstances, this Junior Subordinated
Debenture may become due and payable at the option of the Company at the
principal amount together with any interest accrued thereon (the "Redemption
Price"). The Redemption Price shall be paid prior to 2:00 p.m. Bloomfield Hills,
Michigan 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 Junior Subordinated
Debenture at the option of the Company, in whole or in part, from time to time,
on or after ________________, 2004, at a redemption price equal to 100% of the
principal amount to be redeemed plus any accrued but unpaid interest thereon to
the date of such redemption. Any redemption pursuant to this paragraph will be
made upon not less than 30 days' nor more than 60 days' notice. If the Junior
Subordinated Debentures are only partially redeemed by the Company pursuant to
this paragraph, the Junior Subordinated 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 Junior Subordinated Debentures are registered as a
Global Subordinated Debenture (as defined in the Indenture), the Depositary (as
defined in the Indenture) shall determine the principal amount of such Junior
Subordinated Debentures held by each Junior Subordinated Debenture Holder to be
redeemed in accordance with its procedures.

         In the event of redemption of this Junior Subordinated Debenture in
part only, a new Junior Subordinated Debenture 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 Junior Subordinated
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 Junior Subordinated Debentures at the time
Outstanding, as defined in the Indenture, to execute







                                      A-5
<PAGE>   61

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 the rights of the Holders
of the Junior Subordinated Debentures; provided, however, that no such
supplemental indenture shall (i) change the stated maturity of the Junior
Subordinated 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, without the consent of the Holder of each Junior Subordinated
Debenture so affected, or (ii) reduce the aforesaid percentage of Junior
Subordinated Debentures, the Holders of which are required to consent to any
such supplemental indenture, without the consent of the Holders of each Junior
Subordinated Debenture then Outstanding and affected thereby. The Indenture also
contains provisions permitting the Holders of a majority in aggregate principal
amount of the Junior Subordinated Debentures at the time Outstanding, on behalf
of all of the Holders of the Junior Subordinated 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 interest on any of the Junior Subordinated
Debentures. Any such consent or waiver by the registered Holder of this Junior
Subordinated 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 Junior Subordinated Debenture and of any Junior Subordinated 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 Junior Subordinated Debenture.

         No reference herein to the Indenture and no provision of this Junior
Subordinated 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
interest on this Junior Subordinated 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
Junior Subordinated Debentures and from time to time to extend the interest
payment period of such Junior Subordinated 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 Junior Subordinated 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 or extend beyond the Stated
Maturity. 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.

         The Company has agreed that if at any time (a) there shall have
occurred any event of which the Company has actual knowledge that (i) with the
giving of notice or the lapse of time, or both, would constitute an Event of
Default and (ii) in respect to which the Company shall not have taken reasonable
steps to cure, or (b) the Company shall have given notice of its election of an
Extended Interest Payment Period as provided herein and shall not have rescinded
such notice, or such Extended Interest Payment Period, or any extension thereof,
shall be continuing; or (c)






                                      A-6
<PAGE>   62

while the Junior Subordinated Debentures are held by the Trust, the Company
shall be in default with respect to its payment of any obligation under the
Preferred Securities Guarantee, then the Company will not (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 the Junior
Subordinated Debentures) that rank pari passu with or junior in interest to the
Junior 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 Junior
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 Preferred Securities Guarantee and (D) purchases of
common stock related to the issuance of common stock or rights under any of the
Company's benefit plans for its directors, officers or employees).

         As provided in the Indenture and subject to certain limitations therein
set forth, this Junior Subordinated Debenture is transferable by the registered
Holder hereof on the Securities Register of the Company, upon surrender of this
Junior Subordinated Debenture for registration of transfer at the office or
agency of the Trustee 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 such Holder's attorney duly authorized in writing,
and thereupon one or more new Junior Subordinated Debentures of authorized
denominations and for the same aggregate principal amount will be issued to the
designated transferee or transferees. No service charge will be made for any
such transfer, but the 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 Junior
Subordinated Debenture, the Company, the Trustee, any paying agent and the
Securities Registrar (as defined in the Indenture) may deem and treat the
Registered Holder hereof as the absolute owner hereof (whether or not this
Junior Subordinated Debenture shall be overdue and notwithstanding any notice of
ownership or writing hereon made by anyone other than the Securities Registrar)
for the purpose of receiving payment of or on account of the principal hereof
and interest due hereon and for all other purposes, and neither the Company nor
the Trustee nor any paying agent nor any Securities 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 Junior Subordinated 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 Junior Subordinated Debentures are issuable only in registered form
without coupons in denominations of $_____ and any integral multiple thereof.

         interests of the Holders of the Preferred Securities.

              (b) The Preferred Guarantee Trustee shall not be deemed to have

                           PREFERRED GUARANTEE TRUSTEE

         .1. POWERS AND DUTIES OF THE PREFERRED GUARANTEE TRUSTEE.

              (a) This Preferred Securities Guarantee shall be held by the
         Preferred Guarantee Trustee for the benefit of the Holders of the
         Preferred Securities, and the Preferred Guarantee Trustee shall not
         transfer this Preferred Securities Guarantee to any Person except a
         Holder of Preferred Securities exercising such Holder's rights pursuant
         to Section 5.04(b) or to a Successor Preferred Guarantee Trustee on
         acceptance by such Successor Preferred Guarantee Trustee of its
         appointment to act as Successor Preferred Guarantee Trustee. The right,
         title and interest of the Preferred Guarantee Trustee shall




                                       6
<PAGE>   9

         automatically vest in any Successor Preferred Guarantee Trustee, and
         such vesting and cessation of title shall be effective whether or not
         conveyancing documents have been executed and delivered pursuant to the
         appointment of such Successor Preferred Guarantee Trustee.

              (b) If an Event of Default actually known to a Responsible Officer
         of the Preferred Guarantee Trustee has occurred and is continuing, the
         Preferred Guarantee Trustee shall enforce this Preferred Securities
         Guarantee for the benefit of the Holders of the Preferred Securities.

              (c) The Preferred Guarantee Trustee, before the occurrence of any
         Event of Default and after the curing of all Events of Default that may
         have occurred, shall undertake to perform only such duties as are
         specifically set forth in this Preferred Securities Guarantee, and no
         implied covenants shall be read into this Preferred Securities
         Guarantee against the Preferred Guarantee Trustee. In case an Event of
         Default has occurred (that has not been cured or waived pursuant to
         Section 2.06) and is actually known to a Responsible Officer of the
         Preferred Guarantee Trustee, the Preferred Guarantee Trustee shall
         exercise such of the rights and powers vested in it by this Preferred
         Securities Guarantee, and use the same degree of care and skill in its
         exercise thereof, as a prudent person would exercise or use under the
         circumstances in the conduct of such person's own affairs.

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

                   (i) prior to the occurrence of any Event of Default and after
              the curing or waiving of all such Events of Default that may have
              occurred:

                        (A) the duties and obligations of the Preferred
                   Guarantee Trustee shall be determined solely by the express
                   provisions of this Preferred Securities Guarantee, and the
                   Preferred Guarantee Trustee shall not be liable except for
                   the performance of such duties 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 therein, upon any
                   certificates or opinions furnished to the Preferred Guarantee
                   Trustee and conforming to the requirements of this Preferred
                   Securities Guarantee; but in the case of any such
                   certificates or opinions that by any provision hereof are
                   specifically required to be furnished to the Preferred
                   Guarantee Trustee, the Preferred Guarantee Trustee shall be
                   under a duty to examine the same to determine whether or



                                       7
<PAGE>   10

                   not they conform to the requirements of this Preferred
                   Securities Guarantee;

                   (ii) the Preferred Guarantee Trustee shall not be liable for
              any error of judgment made in good faith by a Responsible Officer
              of the Preferred Guarantee Trustee, unless it shall be proved that
              the Preferred Guarantee Trustee was negligent in ascertaining the
              pertinent facts upon which such judgment was made;

                   (iii) the Preferred Guarantee 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 liquidation amount of the Preferred
              Securities relating to the time, method and place of conducting
              any proceeding for any remedy available to the Preferred Guarantee
              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.

              Securities Guarantee, the Preferred Guarantee Trustee shall deem

              suffering or omitting any action hereunder, the Preferred
              Guarantee Trustee (unless other evidence is herein specifically
              prescribed) may, in the absence of bad faith on its part, request
              and conclusively rely upon an Officers' Certificate which, upon

              including such reasonable advances as may be requested by the
              Preferred Guarantee Trustee; provided that, nothing contained in
              this Section 3.02(a)(vi) shall be taken to relieve the Preferred
              Guarantee Trustee, upon the occurrence of an Event of Default, of
              its obligation to exercise the rights and powers vested in it by
              this Preferred Securities Guarantee.

              attorneys, and the Preferred Guarantee 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.

                   (ix) Any action taken by the Preferred Guarantee Trustee or
              its agents hereunder shall bind the Holders of the Preferred
              Securities, and the signature of the Preferred Guarantee Trustee
              or its agents alone shall be sufficient and effective to perform
              any such action. No third party shall be required to inquire as to
              the authority of the Preferred Guarantee Trustee to so act or as
              to its compliance with any of the terms and provisions of this
              Preferred Securities Guarantee, both of

              Preferred Guarantee Trustee (A) may request instructions from the
              Holders of a Majority in liquidation amount of the Preferred
              Securities, (B) may refrain from enforcing such remedy or right or
              taking such other action until such instructions are received, and
              (C) shall be protected in conclusively relying on or acting in
              accordance with such instructions.

              (b) No provision of this Preferred Securities Guarantee shall be
         deemed to impose any duty or obligation on the Preferred Guarantee

                           PREFERRED GUARANTEE TRUSTEE

         .1. PREFERRED GUARANTEE TRUSTEE; ELIGIBILITY.

              (a) There shall at all times be a Preferred Guarantee Trustee
         which shall:

                   (i) not be an Affiliate of the Guarantor; and

                   (ii) 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 Person
              permitted by the Securities and Exchange Commission to act as an
              institutional trustee under the Trust Indenture Act, authorized
              under such laws to exercise corporate trust powers, having a
              combined capital and surplus of at least with respect to the
              initial Trustee $500,000 (and its principal parent holding company
              having a combined capital and surplus of at least $50,000,000) and
              with respect to any successor Trustee $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 supervising or examining authority referred to
              above, then, for the purposes of this Section 4.01(a)(ii), 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.

              (b) If at any time the Preferred Guarantee Trustee shall cease to
         be eligible to so act under Section 4.01(a), the Preferred Guarantee
         Trustee shall immediately resign in the manner and with the effect set
         out in Section 4.02(c).

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

         .2. APPOINTMENT, REMOVAL AND RESIGNATION OF PREFERRED GUARANTEE
TRUSTEES.

              (a) Subject to Section 4.02(b), the Preferred Guarantee Trustee
         may be appointed or removed without cause at any time by the Guarantor.

              (b) The Preferred Guarantee Trustee shall not be removed in
         accordance with Section 4.02(a) until a Successor Preferred Guarantee
         Trustee has been appointed and has accepted such appointment by written
         instrument executed by such Successor Preferred Guarantee Trustee and
         delivered to the Guarantor.

              (c) The Preferred Guarantee Trustee appointed to office shall hold
         office until a Successor Preferred Guarantee Trustee shall have been
         appointed or until its removal or resignation. The Preferred Guarantee
         Trustee may resign from office (without need for





                                       11
<PAGE>   14


         prior or subsequent accounting) by an instrument in writing executed by
         the Preferred Guarantee Trustee and delivered to the Guarantor, which
         resignation shall not take effect until a Successor Preferred Guarantee
         Trustee has been appointed and has accepted such appointment by
         instrument in writing executed by such Successor Preferred Guarantee
         Trustee and delivered to the Guarantor and the resigning Preferred
         Guarantee Trustee.

              (d) If no Successor Preferred Guarantee Trustee shall have been
         appointed and accepted appointment as provided in this Section 4.02
         within 60 days after delivery to the Guarantor of an instrument of
         resignation, the resigning Preferred Guarantee Trustee may petition any
         court of competent jurisdiction for appointment of a Successor
         Preferred Guarantee Trustee. Such court may thereupon, after
         prescribing such notice, if any, as it may deem proper, appoint a
         Successor Preferred Guarantee Trustee.

              (e) No Preferred Guarantee Trustee shall be liable for the acts or
         omissions to act of any Successor Preferred Guarantee Trustee.

              (f) Upon termination of this Preferred Securities Guarantee or
         removal or resignation of the Preferred Guarantee Trustee pursuant to
         this Section 4.02, the Guarantor shall pay to the Preferred Guarantee
         Trustee all amounts accrued to the date of such termination, removal or
         resignation.

         .1. GUARANTEE. The Guarantor irrevocably and unconditionally agrees to
pay in full to the Holders the Guarantee Payments (without duplication of
amounts theretofore paid by Flagstar Trust), as and when due, regardless of any
defense, right of set-off or counterclaim that Flagstar Trust may have or
assert. The Guarantor's obligation to make a Guarantee Payment may be satisfied
by direct payment of the required amounts by the Guarantor to the Holders or by
causing Flagstar Trust to pay such amounts to the Holders.

         .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, presentment, demand for payment, any right to require a
proceeding first against Flagstar Trust or any other Person before proceeding
against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice
of redemption and all other notices and demands.

         payable that results from the extension of any interest payment period
         on the Junior Subordinated Debentures or any extension of the maturity
         date of the Junior Subordinated Debentures permitted by the Indenture);

              (c) any failure, omission, delay or lack of diligence on the part
         of the Holders to enforce, assert or exercise any right, privilege,
         power or remedy conferred on the Holders pursuant to the terms of the
         Preferred Securities, or any action on the part of Flagstar Trust
         granting indulgence or extension of any kind;

              (d) the voluntary or involuntary liquidation, dissolution, sale of
         any collateral, receivership, insolvency, bankruptcy, assignment for
         the benefit of creditors, reorganization, arrangement, composition or
         readjustment of debt of, or other similar proceedings affecting,
         Flagstar Trust or any of the assets of Flagstar Trust;

              (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 5.03 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.

         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 Flagstar Trust, the Preferred Guarantee Trustee or
         any other Person.

         .5. GUARANTEE OF PAYMENT. This Preferred Securities Guarantee creates a
Guarantee of payment and not of collection.

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

Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

obligations hereunder are independent of the obligations of Flagstar Trust with
respect to the Preferred Securities, and that the Guarantor shall be liable as

stock, (b) the Guarantor shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by

the Guarantor shall not make any guarantee payments with respect to any
guarantee by the guarantor of the debt securities of any subsidiary of the
Guarantor if such guarantee ranks pari passu or junior in interest to the Junior
Subordinated Debentures (other than (i) dividends or distributions in common

Preferred Securities or under this Preferred Securities Guarantee.

         Re:      Registration Statement on Form S-3

Ladies and Gentlemen:

         You have requested our opinion as special counsel to Flagstar Bancorp,
Inc. (the "Company") and Flagstar Trust (the "Trust") in connection with
securities to be offered pursuant to the Registration Statement on Form S-3 to
be filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "Registration Statement"). The Registration Statement
relates to the registration of 2,990,000 preferred securities of the Trust (the
"Preferred Securities") in connection with the proposed offer and sale of such
Preferred Securities by the Trust.

         In rendering this opinion, we understand that the Preferred Securities
will be offered and sold in the manner described in the Prospectus, which is a
part of the Registration Statement. We have examined such records and documents
and made such examination as we have deemed relevant in connection with this
opinion.

         Based upon the foregoing, it is our opinion that:

         1. The Preferred Securities have been, and when issued and sold as
contemplated by the Registration Statement, will be, legally issued, fully paid
and nonassessable.

         2. The Guarantee, when executed and delivered as contemplated by the
Registration Statement, and the Junior Subordinated Debentures, when issued and
paid for as contemplated by the Registration Statement, will be validly issued
obligations of the Company enforceable in accordance with their terms except as
such enforceability may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting the rights of creditors generally and subject to general
principles of equity.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm in the Prospectus under
the heading "Legal Matters."

                                 Very truly yours,


                                 /s/ Kutak Rock

               Re: Flagstar Trust

Ladies and Gentlemen:

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

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

         (a) The Trust Agreement of the Trust, dated as of March   , 1999,
between Flagstar Bancorp, Inc., a Michigan Corporation (the "Company"), and the
trustees of the Trust named therein;

         (b) The Certificate of Trust of the Trust, as filed in the office of
the Secretary of State of the State of Delaware (the "Secretary of State") on
March 25, 1999 (the "Certificate");

         (c) The Registration Statement (the "Registration Statement") on Form
S-3, including a prospectus (the "Prospectus") relating to, among other things,
   % Cumulative Trust Preferred Securities (Liquidation Amount $25.00 per
Preferred Security) of the Trust representing preferred undivided beneficial 
interests in the assets 


<PAGE>   2

of the Trust (each, a "Preferred Security", and collectively, the "Preferred
Securities"), as proposed to be filed by the Company, the Trust and others as
set forth therein with the Securities and Exchange Commission on or about March
   , 1999;

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

         (e) A Certificate of Good Standing for the Trust, dated March   , 1999,
obtained from the Secretary of State.

         Unless otherwise defined herein, all capitalized terms used in this
opinion letter shall have the respective meanings provided in the Agreement,
except that reference herein to any document shall mean such document as in
effect on the date hereof.

         For the purposes of this opinion letter, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that 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, (iii) the genuineness of all signatures, and (iv) such documents
submitted to us in final or execution form have not been and will not be altered
or amended in any respect material to our opinions as expressed in this letter
and conform in all material respects to the final, executed originals of such
documents.

         For purposes of this opinion letter, we have assumed (i) that the
Agreement constitutes the entire agreement among the parties thereto with
respect to the creation, operation, and termination of the Trust, and that the
Agreement and the Certificate are in full force and effect and have not been
amended, (ii) that there are no proceedings, pending or contemplated, for the
merger, consolidation, liquidation, dissolution or termination of the Trust,
(iii) except to the extent provided in paragraph 1 below, the due creation, due
formation or due organization, 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, formation or organization, (iv) the
legal capacity of each natural person who is a party to the documents examined
by us, (v) 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, (vi) that each of the parties to the documents examined
by us has duly authorized, executed and delivered such documents, (vii) the
receipt by each Person to whom a Preferred Security is to be issued by the Trust
(collectively, the "Preferred Securities Holders") of an appropriate certificate
for such Preferred Security, and the payment for the Preferred Security acquired
by it, in accordance with the Agreement and the Registration Statement, and
(viii) that the Preferred Securities are issued to the Preferred Securities
Holders in accordance with the Agreement and the Registration Statement. We have
not participated in the preparation of the Registration Statement and assume no
responsibility for its contents.

         The opinions in this letter are 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 the federal laws of the United States of America and rules and
regulations relating thereto.

         Based upon the foregoing, and subject to the assumptions,
qualifications, limitations and exceptions set forth herein, we are of the
opinion that:

         1. The Trust has been duly formed 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 Securities 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 Securities
Holders may be obligated to make payments as provided in the Agreement.

         We consent to the filing of this opinion letter 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

thereunder. Except as stated above, without our prior written consent, this

Person for any purpose.

         Re:      Preferred Securities of Flagstar Trust

Ladies and Gentlemen:

         We have acted as special tax counsel for Flagstar Bancorp, Inc. (the
"Company"), a Michigan corporation, and Flagstar Trust (the "Trust"), a
statutory business trust organized under the Business Trust Act of the State of
Delaware (12 Del. Code Ann., tit. 12, Section 3801, et seq.), in connection with
the sale, pursuant to an underwriting agreement (the "Underwriting Agreement")
to be entered into among the Company, the Trust, and the underwriters (the
"Underwriters") named therein, of trust preferred securities (the "Preferred
Securities") (liquidation amount $25 per Preferred Security), which will
represent undivided beneficial interests in the assets of the Trust.

         The Preferred Securities will be guaranteed by the Company with respect
to distributions and payments upon liquidation, redemption, and otherwise
pursuant to the guarantee agreement (the "Guarantee Agreement"), to be entered
into, between the Company and FMB Bank, as trustee (the "Guarantee Trustee"),
for the benefit of the holders of the Preferred Securities.

         In connection with the issuance of the Preferred Securities, the Trust
will also issue common securities (the "Common Securities") (liquidation amount
$25 per Common Security), which will represent undivided beneficial interests in
the assets of the Trust.
<PAGE>   2
Flagstar Bancorp, Inc.
Flagstar Trust

Page 2 of 5



         The proceeds from the sale of the Preferred Securities and the Common
Securities are to be used by the Trust to purchase junior subordinated
debentures (the "Junior Subordinated Debentures"), to be issued by the Company.
The Preferred Securities and the Common Securities are to be issued pursuant to
the Amended and Restated Trust Agreement (the "Trust Agreement"), to be entered
into among the Company, as depositor, First Omni Bank, National Association
(Delaware), as Delaware trustee (the "Delaware Trustee"), FMB Bank, as property
trustee (the "Property Trustee"), and the administrative trustees (the
"Administrative Trustees") named therein. The Junior Subordinated Debentures are
to be issued pursuant to an indenture (the "Indenture"), to be entered into,
between the Company and FMB Bank, as indenture trustee.

         In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the preliminary
Prospectus dated March 26, 1999; (ii) the Certificate of Trust filed with the
Secretary of State of the State of Delaware as of March 25, 1999, by the
Administrative Trustees, and the Delaware Trustee; (iii) the form of the Trust
Agreement including the designation of the terms of the Preferred Securities;
(iv) the form of the Preferred Securities and a specimen certificate thereof;
(v) the form of the Guarantee Agreement; (vi) the form of the Indenture; (vii)
the form of Junior Subordinated Debentures and a specimen certificate thereof;
(viii) the form of Common Securities and a specimen certificate thereof; and
(ix) the form of the Underwriting Agreement. We have also examined originals or
copies, certified or otherwise identified to our satisfaction, of such records
of the Company and the Trust and such agreements, certificates of public
officials, certificates of officers, trustees or other representatives of the
Company, the Trust and others, as applicable, and such other documents,
certificates and records as we have deemed necessary or appropriate as a basis
for the opinions set forth herein.

         In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies, and the
authenticity of the originals of such latter documents. In making our
examination of documents executed, or to be executed by parties other than the
Company or the Trust, we have assumed that such parties had, or will have, the
power, corporate or other, to enter into and perform all obligations thereunder,
and we have also assumed the due authorization by all requisite action,
corporate or other, and execution and delivery by such parties of such documents
and that such documents constitute, or will constitute, valid and binding
obligations of such parties. As to any facts material to the opinions expressed
herein which were not independently established or verified, we have relied upon
oral or written statements and representations of officers, trustees and other
representatives of the Company, the Trust, and others.

         In rendering our opinion, we have participated in the preparation of
the preliminary Prospectus. Our opinion is conditioned on, among other things,
the initial and continuing accuracy of the facts, information, covenants,
representations, and assumptions set forth in the documents referred to above
and the statements and representations made by the Company and the Trust. In
rendering our opinion, we have considered the provisions of the Internal Revenue
Code of 1986, as amended, Treasury regulations (proposed, temporary, and final)
promulgated thereunder, judicial decisions, and Internal Revenue Service rulings
all as of the date hereof, and all of which are subject to change, which changes
may be retroactively applied. A change in the authorities upon which our opinion
is based could affect our conclusions. There can be no assurance, moreover, that
any of the opinions expressed herein will be accepted by the Internal Revenue
Service or, if challenged, by a court.

         Based solely upon the foregoing, we are of the opinion that under
current United States federal income tax law:

                  (1) The Trust should be classified as a grantor trust and not
         as an association taxable as a corporation. Accordingly, each holder of
         Preferred Securities will generally be treated as the owner of an
         undivided interest in the Junior Subordinated Debentures.

                  (2) The Junior Subordinated Debentures should be classified as
         indebtedness of the Company.

                  (3) Assuming that the likelihood of the exercise by the
         Company of the election to defer the payment of interest on the Junior
         Subordinated Debentures is remote, the Junior Subordinated Debentures
         will not be deemed to be issued with original issue discount.
         Accordingly, stated interest payments on the Junior Subordinated
         Debentures will be includible in a holder's income at the time those
         payments are paid or accrued in accordance with a holder's regular
         method of accounting. A determination as to the remoteness of a
         contingency under United States federal income tax law is inherently a
         factual determination, and thus, no opinion is expressed herein
         regarding the remoteness of the likelihood of the exercise of the
         Company's election to defer the payment of interest on the Junior
         Subordinated Debentures.

                  (4) If the Company exercises its option to defer the payment
         of stated interest, (i) solely for purposes of the original issue
         discount rules, the Junior Subordinated Debentures would be treated as
         being "reissued," (ii) the amount of interest income includible in the
         taxable income of a holder of the Junior Subordinated Debentures would
         be determined on the basis of a constant yield method over the
         remaining term of the Junior Subordinated Debentures, (iii) the actual
         receipt of future payments of stated interest on the Junior
         Subordinated Debentures would no longer be separately reported as


                                       3
<PAGE>   4
Flagstar Bancorp, Inc.
Flagstar Trust

Page 4 of 5

         taxable income, (iv) any original issue discount included in income
         would increase the holder's adjusted tax basis in the Preferred
         Securities or the Junior Subordinated Debentures, as the may be, and
         (v) the holder's actual receipt of interest payments would reduce the
         holder's adjusted tax basis.

                  (5) Because payments on the Preferred Securities will be
         treated as interest income for United States federal income tax
         purposes, corporate holders of Preferred Securities will not be
         entitled to claim a dividends received deduction.

                  (6) If the Company exercises its right to liquidate the Trust
         and cause the Junior Subordinated Debentures to be distributed to
         holders on a basis proportionate to a holder's ownership in the
         Preferred Securities, such a distribution will be treated as a
         nontaxable event to a holder, provided that the Trust is classified,
         for United States federal income tax purposes, as a grantor trust and
         not an association taxable as a corporation at the time of the
         liquidation. In such event, a holder will have an adjusted tax basis in
         the Junior Subordinated Debentures received in the liquidation of the
         Trust equal to such holder's adjusted tax basis in the Preferred
         Securities surrendered and the holding period of the Junior
         Subordinated Debentures will include the period during which the holder
         held the Preferred Securities.

                  (7) If the Trust is characterized, for United States federal
         income tax purposes, as an association taxable as a corporation at the
         time of the liquidation of the Trust, the distribution of Junior
         Subordinated Debentures would be taxable to holders.

                  (8) Upon the sale or redemption for cash of Preferred
         Securities, a holder will recognize gain or loss in an amount equal to
         the difference between (i) the holder's adjusted tax basis in the
         Preferred Securities and (ii) the amount realized in the sale, except
         for any amount received for accrued but unpaid interest not previously
         included in income.

                  (9) The gain or loss on the sale or redemption for cash of
         Preferred Securities will be long term capital gain or loss if a holder
         held the Securities as capital assets for United States federal income
         tax purposes for more than one year, provided that the holder will be
         required to include in ordinary income any portion of the amount
         realized in the sale that is attributable to (i) accrued but unpaid
         interest to the extent not previously included in income and (ii) any
         amount of original issue discount that has accrued on a holder's
         proportionate share of the underlying Junior Subordinated Debentures
         during the taxable year through the date of disposition.

                  (10) Capital losses generally cannot be applied to offset
         ordinary income.

                  (11) Payments made to non-U.S. Holders (as defined in the
         preliminary Prospectus) will generally not be subject to withholding of
         United States federal income tax if (A) the beneficial owner of the
         Preferred Securities does not actually or constructively own 10% or
         more of the total combined voting power of all classes of the stock of
         the Company entitled to vote and (B) either (i) the beneficial owner of
         the Preferred Securities certifies to the Trust or its agent, under
         penalties of perjury, that it is not a United States person and
         provides his name and address or (ii) a securities clearing
         organization, bank or other financial institution that holds customers'
         securities in the ordinary course of its trade or business ("Financial
         Institution"), and holds the Preferred Securities in that capacity,
         certifies to the Trust or its agent, under penalties of perjury, that
         such statement has been received from the beneficial owner by it or by
         a Financial Institution between it and the beneficial owner and
         furnishes the Trust or its agent with a copy of the statement.
