                                     PART I
 
ITEM 1. BUSINESS
 
GENERAL
 
     Flagstar Capital Corporation (the "Company") was incorporated in Michigan
in June 1995 and remained dormant until reorganized in December 1997. The
Company was formed by Flagstar Bank (the "Bank"), a federally chartered savings
bank, to provide the Bank and its parent holding company and sole stockholder,
Flagstar Bancorp, Inc. ("Flagstar"), with a means of raising capital for bank
regulatory purposes in a cost-effective manner.
 
     The principal business of the Company is to acquire and hold residential
mortgage loans ("Mortgage Loans") that will generate net income for distribution
to stockholders. The Company intends to acquire all its Mortgage Loans from the
Bank, consisting of whole loans secured by first mortgages on single-family
residential real estate properties. The residential mortgage loans consist of
Adjustable Rate Mortgages ("ARMs") and Fixed Rate Mortgages ("FRM's").
 
     On February 24, 1998, the Company offered to the public and sold 2,000,000
shares of the Company's 8.50%, noncumulative, Series A Preferred Shares, $25 par
value per share, providing gross proceeds totaling $50.0 million (the "Series A
Preferred Shares"), and sold to the Bank, 499,900 shares of the Company's common
stock, $1.00 par value providing proceeds totaling $65.5 million (the "Common
Stock").
 
     On May 24, 1998, in response to the underwriters exercising their
over-allotment option, the Company issued an additional 300,000 shares of its
Series A Preferred Shares, to the public and 500,000 shares of Common Stock to
the Bank, providing additional gross proceeds totaling $17.0 million. All shares
of Common Stock are held by the Bank. The Series A Preferred Shares are traded
on the Nasdaq Stock Market(R), under the symbol "FLGSP".
 
     The Company used the net proceeds raised from the initial public offering
of the Series A Preferred Shares and the sale of the Common Stock to the Bank to
purchase from the Bank the Company's initial portfolio of $113.5 million of
Mortgage Loans ("Initial Portfolio"). The Company's Initial Portfolio consisted
of ARMs and FRM's. Reinvestments made in Mortgage Loans have been and will
continue to be made with a composition of Mortgage Loans that will allow the
Company to maintain the original composition of approximately 70% ARMs and 30%
FRM's. Mortgage Loans are purchased from the Bank on a fair value basis.
 
     In order to preserve its status as a real estate investment trust ("REIT")
under the Internal Revenue Service Code ("Code"), the Company must distribute
annually at least 95% of its "REIT taxable income" (excluding capital gains) to
stockholders and meet certain capital ownership and administrative tests as
defined by the Code. The Company must also annually satisfy three gross income
requirements. First, at least 75% of the Company's gross income for each taxable
year must be derived directly or indirectly from investments relating to real
property or mortgages on real property or from certain types of temporary
investments. Second, at least 95% of the Company's gross income for each taxable
year must be derived from the above described real property investments and from
dividends, interest, and gain from the sale or other disposition of stock or
securities and certain other types of gross income. Third, short-term gains from
the sale or other disposition of stock or securities, and gains on the sale or
other disposition of real property held for less than four years (apart from
involuntary conversions and sales of foreclosure property) from the date of
acquisition must represent less than 30% of the Company's gross income for each
taxable year.
 
     The Company must also satisfy three tests relating to the nature of its
assets at the close of each quarter of its taxable year. First, at least 75% of
the value of the Company's total assets must be represented by real estate
assets. Second, not more than 25% of the Company's total assets may be
represented by securities other than those in the 75% asset class. Third, of the
investments included in the 25% asset class, the value of any one issuer's
securities owned by the Company may not exceed 5% of the value of the Company's
total assets and the Company may not own more than 10% of any one issuer's
outstanding voting securities.
 
                                        3
<PAGE>   4
 
     The Company does not anticipate that it will engage in the business of
originating Mortgage Loans and does not expect to compete with mortgage conduit
programs, investment banking firms, savings and loan associations, banks, thrift
and loan associations, finance companies, mortgage bankers or insurance
companies in acquiring its Mortgage Loans. As noted above, the Company has
purchased all of its Mortgage Loans from the Bank and intends on making all of
its future purchases from the Bank.
 
     The Company has entered into an Advisory Agreement (the "Advisory
Agreement") with the Bank (the "Advisor") requiring an annual payment of
$250,000. The Bank provides advice to the Board of Directors and manages the
operations of the Company as defined in the Agreement. The Agreement has an
initial term of five years which commenced on February 24, 1998 and will
automatically renew for additional five year periods, unless the Company
delivers prior notice to the Advisor as defined in the Advisory Agreement.
 
     The Company also entered into a Servicing Agreement (the "Servicing
Agreement") with the Bank for the servicing of the Mortgage Loans. Pursuant to
the Servicing Agreement, the Bank services the Mortgage Loans held by the
Company, in accordance with normal industry practices. The Servicing Agreement
can be terminated without cause upon a thirty day advance notice and payment of
a termination fee equal to 2% of the aggregate outstanding principal amount of
the loans then serviced under the Agreement. The servicing fee is 0.375% per
annum of the outstanding principal balance of the Mortgage Loans.
 
     The Company operations are conducted in a manner that will not subject it
to regulation under the Investment Company Act of 1940. The Company may, under
certain circumstances, purchase the Series A Preferred Shares and other shares
of its capital stock in the open market or otherwise, provided, however, that
the Company will not redeem or repurchase any shares of its Common Stock for so
long as any Series A Preferred Shares are outstanding without the approval of a
majority of the Independent Directors. The Company has no present intention of
repurchasing any shares of its capital stock, and any such action would be taken
only in conformity with applicable federal and state laws and the regulations
and the requirements for qualifying as a REIT.
 
     The Company has no foreign operations.
 
ITEM 2. PROPERTIES
 
     The principal executive offices of the Company are located at 2600
Telegraph Road, Bloomfield Hills, Michigan 48302 and its telephone number is
(248) 338-7700.
 
ITEM 3. LEGAL PROCEEDINGS
 
     The Company is not the subject to any litigation. The Company is not
currently involved in nor, to the Company's knowledge, currently threatened with
any litigation with respect to the Mortgage Loans included in the portfolio.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     None
 
                                    PART II
 
ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
 
     The Company is authorized to issue up to 1,000,000 shares of Common Stock
and 2,300,000 shares of Preferred Stock, $25 par value per share ("Preferred
Stock"). All of the 1,000,000 shares of Common Stock and all of the 2,300,000
shares of Preferred Stock have been issued. The Bank owns 100% of the Company's
1,000,000 shares of Common Stock outstanding at December 31, 1998 and,
accordingly, there is no trading market for the Company's Common Stock. In
addition, the Bank intends that, as long as any Series A Preferred Shares are
outstanding, it will maintain ownership of the outstanding Common Stock of the
 
                                        4
<PAGE>   5
 
Company. All voting rights are vested in the Common Stock. The holder of Common
Stock is entitled to one vote per share. Holders of Common Stock are entitled to
receive dividends when, and if declared by the Board of Directors of the Company
out of funds legally available. No dividends or other distributions may be made
with respect to the Common Stock as long as any shares of Preferred Stock are
outstanding and the full dividends on those shares have not been paid. The
Company must distribute annually at least 95% of its annual "REIT taxable
income" to stockholders.
 
     In the event of the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, after there have been set aside for the
holders of Preferred Stock the full preferential amounts to which such holders
are entitled, the holders of Common Stock will be entitled to any assets
remaining after the payment of all debts and liabilities.
 
RESTRICTIONS ON OWNERSHIP AND TRANSFER:
 
     The Company's Certificate of Incorporation contains certain restrictions on
the number of shares of Common Stock and Preferred Stock that individual
stockholders may own. For the Company to qualify as a REIT under the Code, no
more than 50% in number or value of its outstanding shares of capital stock may
be owned, directly or indirectly, by five or fewer individuals during the last
half of a taxable year or during a proportionate part of a shorter taxable year
(the "Five or Fewer Test"). The capital stock of the Company must also be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year or during a proportionate part of a shorter taxable year (the "One Hundred
Person Test"). The ownership by the Bank of 100% of the shares of Common Stock
of the REIT will not adversely affect the Company's REIT qualification because
each stockholder of Flagstar Bancorp, Inc. (the sole stockholder of the Bank)
counts as a separate beneficial owner for purposes of the Five or Fewer Test and
the capital stock of Flagstar Bancorp, Inc. is widely held. Further, the
Certificate of Incorporation of the Company contains restrictions on the
acquisition of Preferred Stock intended to ensure compliance with the One
Hundred Persons Test. Such provisions include a restriction that if any transfer
of shares of capital stock of the Company would cause the Company to be
beneficially owned by fewer than 100 persons, such transfer shall be null and
void and the intended transferee will acquire no rights to the stock.
 
COMMON STOCK
 
     There is no established public trading market in the Company's Common
Stock. As of March 15, 1999, there were 1,000,000 issued and outstanding shares
of Common Stock held by one stockholder, the Bank. The following table reflects
the distributions paid or payable by the Company on the Common Stock since the
Company's initial capitalization on February 24, 1998.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
OVERVIEW
 
     Flagstar Capital Corporation was formed by Flagstar Bank, a federally
chartered savings bank, to provide the Bank and its parent holding company and
sole stockholder, Flagstar Bancorp, Inc., with a means of raising capital for
bank regulatory purposes in a cost-effective manner.
 
     The principal business of the Company is to acquire and hold residential
mortgage loans that will generate net income for distribution to stockholders.
The Company intends to acquire all its Mortgage Loans from the Bank, consisting
of whole loans secured by first mortgages on single-family residential real
estate properties. The residential mortgage loans consist of Adjustable Rate
Mortgages ("ARMs"), and Fixed Rate Mortgages ("FRM's").
 
     On February 24, 1998, the Company sold in a public offering 2,000,000
shares of the Company's 8.50%, noncumulative, Series A Preferred Shares, $25 par
value per share, providing gross proceeds totaling $50.0 million (the "Series A
Preferred Shares"), and sold to the Bank, 499,900 shares of the Company's common
stock, $1.00 par value providing proceeds totaling $65.5 million (the "Common
Stock").
 
     On May 24, 1998, in response to the underwriters exercising their
over-allotment option, the Company issued an additional 300,000 shares of its
Series A Preferred Shares, to the public and 500,000 shares of Common Stock to
the Bank, providing additional gross proceeds totaling $17.0 million, gross. All
shares of common stock are held by the Bank. The Series A Preferred Shares are
traded on the Nasdaq Stock Market, under the symbol "FLGSP".
 
RESULTS OF OPERATIONS
 
     The Company reported net earnings for the period ended December 31, 1998 of
$6.2 million. Interest income from loans was $6.6 million, which was offset by
approximately $213,000 in advisory fees, $6,000 in outside directors fees, and
$104,000 in other administrative expenses. The Company reported earnings per
common share of $2.50 for the period ended December 31, 1998.
 
     The Company declared and paid $4,149,000 in preferred stock dividends for
the period ended December 31, 1998.
 
     The Company declared and paid or accrued $2,093,000 in common stock
dividends for the period ended December 31, 1998.
 
MORTGAGE LOANS
 
     As of December 31, 1998, the Company owned Mortgage Loans with a principal
balance of $115,380,000. This amount represents the remaining principal amount
of mortgage loans purchased with the Initial Portfolio plus the principal amount
of mortgage loans purchased during the period beginning on February 24, 1998 and
ending on December 31, 1998. Purchases made during the period ending December
31, 1998 were made to replace principal amortizations and payoffs in the
portfolio. All Mortgage Loans were purchased from the Bank. In conjunction with
the purchase of these Mortgage Loans the Company paid a premium amount equal to
$1.3 million. This premium amount is recorded by the Company as an adjustment to
the basis of the Mortgage Loans.

     ALLOWANCE FOR LOSSES. The Company did not have an allowance for losses at
December 31, 1998. The Company's non-performing loans were limited to three
mortgage loans, totaling $342,969, or 0.30% of the portfolio, that were 30 days
delinquent. The Company has certain representations and warranties which are
related to the performance of the Mortgage Loans.
 
     The Company expects to record an allowance for losses during 1999 which
will be based upon management's assessment of relevant factors, including the
types and amounts of delinquent loans, historical and anticipated loss
experience on such types of loans experienced by the Bank, and current and
projected economic conditions.
 
     The Bank, in its role as Advisor, has implemented comprehensive internal
asset review systems to provide for early detection of problem assets. Although
this system will not eliminate future losses due to unanticipated declines in
the real estate market or economic downturns, it should provide for timely
identification of any losses created from problem loans.
 
INTEREST RATE RISK
 
     The Company's income consists primarily of interest payments on Mortgage
Loans. Currently, the Company does not use any derivative products to manage
interest rate risk. If there is a decline in interest rates (as measured by the
indices upon which the interest rates of the Adjustable Rate Mortgage Loans are
based), then the Company will experience a decrease in income available to be
distributed to its shareholders. There can be no assurance that an interest rate
environment in which there is a significant decline in interest rates, over an
extended period of time, would not adversely affect the Company's ability to pay
dividends on the Series A Preferred Shares.
 
SIGNIFICANT CONCENTRATION OF CREDIT RISK
 
     Concentration of credit risk arises when a number of customers engage in
similar business activities, or activities in the same geographical region, or
have similar economic features that would cause their ability to meet
contractual obligations to be similarly affected by changes in economic
conditions. Concentration of credit risk indicates the relative sensitivity of
the Company's performance to both positive and negative developments affecting a
particular industry. The geographic concentrations within the Mortgage Loans
directly affects the overall credit risk of the Company.

-------------------------
* No other state has more than 3% of the total Mortgage Loan portfolio
 
     Approximately 40.1% of the Company's total Mortgage Loans are secured by
residential real estate properties located in California and Michigan.
Consequently, these residential mortgage loans may be subject to a greater risk
of default than other comparable residential mortgage loans in the event of
adverse economic, political or business developments and natural hazards in
California and Michigan that may affect the ability of residential property
owners in California and Michigan to make payments of principal and interest on
the underlying mortgages.
 
LIQUIDITY RISK MANAGEMENT
 
     The objective of liquidity management is to ensure the availability of
sufficient cash flows to meet all of the Company's financial commitments. In
managing liquidity, the Company takes into account various legal limitations
placed on a REIT as discussed below in REIT Qualification.
 
     The Company's principal liquidity needs are to maintain the current
portfolio size through the acquisition of additional Mortgage Loans as Mortgage
Loans currently in the portfolio mature or prepay, and to pay dividends on the
Series A Preferred Shares and Common Shares issued. The Company does not have
and does not anticipate having any material capital expenditures.
 
     To the extent that the Board of Directors determines that additional
funding is required, the Company may raise such funds through additional equity
offerings, debt financing or retention of cash flow (after consideration of
provisions of the Code pertaining to a REIT), or a combination of these methods.
The Company, however, may not, without the approval of a majority of the
Independent Directors, incur debt in excess of 20% of the aggregate amount of
the net proceeds received from the sale of the Series A Preferred Shares and
Common Stock of the Company. This limitation includes intercompany advances made
by the Bank to the Company.
 
     The Company may also issue additional series of Preferred Stock. However,
the Company may not issue additional shares of Preferred Stock senior to the
Series A Preferred Shares without the consent of holders of at least 66 2/3% of
the shares of Preferred Stock outstanding at that time. The Company also may not
issue additional shares of Preferred Stock on a parity with the Series A
Preferred Shares without the approval of a majority of the Company's Independent
Directors.
 
MARKET RISK
 
     The Company considers that its primary business objective is to ensure the
availability of sufficient cash flows to meet the obligations mandated by the
Series A Preferred Shares. In managing its investments, the Company accepts a
certain credit risk posture and assumes some interest rate risk.
 
     Interest rate risk generally refers to the potential volatility in net
interest income resulting from changes in interest rates. The Company's interest
rate risk management focuses on the replacement of amortized loans with current
production mortgages. These replacement loans are chosen in a manner to maintain
an interest rate risk posture similar to the Initial Portfolio. The Company must
monitor the ratio of fixed costs (the
 
                                        9
<PAGE>   10
 
Series A Preferred Shares' dividends, advisory fees, and servicing costs) to the
interest income potential of the Mortgage Loans. When, in management's opinion,
the coverage ratio is at risk of being depleted, the Company must look to its
parent company, the Bank, for support or utilize the investment powers of the
Company.
 
     The Company will record higher levels of interest income in a rising
interest rate environment and will experience declining interest income during
periods of falling interest rates. This happens because the Company's assets
reprice while the Series A Preferred Shares have a fixed cost of 8.5%.
 
     At December 31, 1998 the Company had a coverage ratio (Projected interest
income divided by REIT dividends plus Advisory fees) of 1.53 versus the coverage
ratio at inception of 1.67.
 
REIT QUALIFICATION
 
     As of December 31, 1998, the Company believed that it was in compliance
with the REIT tax rules and that it will continue to qualify as a REIT under the
provisions of the Code. The Company calculates:
 
     - its Qualified REIT Assets, as defined in the Code, to be 100% of its
       total assets, as compared to the federal tax requirements that at least
       75% of its total assets must be Qualified REIT assets.
 
     - that 100% of its revenues qualify for the 75% source of income test and
       100% of its revenues qualify for the 95% source of income test under the
       REIT rules.
 
     - none of the revenues were subject to the 30% income limitation under the
       REIT rules.
 
     The Company also met all REIT requirements regarding the ownership of its
common and preferred stocks.
 
YEAR 2000 COMPLIANCE
 
     As with many other companies, the Company is dependant on others for its
computer technology. Flagstar provides computer programming and administrative
services through the Advisory Agreement and the Servicing Agreement.
 
     Flagstar's computer programs and other applications were originally
designed to recognize calendar years by their last two digits. Calculations
performed using these truncated fields will not work properly with dates from
the year 2000 and beyond. Many of the systems utilized by Flagstar are
vendor-supplied and almost all of these vendors have provided Flagstar with a
certification of compliance or have given a completion date within the first
quarter of 1999. Flagstar began reviewing its year 2000 conversion needs
mid-1996 and has two project committees that are monitoring the status of these
conversions. A comprehensive review to identify the systems affected by this
issue was completed and an implementation plan was compiled and is currently
being executed. Flagstar has not and does not expect to spend any significant
amounts with outside contractors relative to the completion of these tasks.
Therefore, costs do not represent any material incremental costs, but rather
will represent the redeployment of existing technology resources. Flagstar
presently believes that with the planned modifications to existing systems and
vendor delivery of millennium-compliant systems, all year 2000 compliance issues
will be resolved no later than the end of the first quarter of 1999.
Additionally, Flagstar believes that any related costs will not have a material
impact on the operations, cash flows, or financial condition of future periods.
 
     Although Flagstar has conducted internal development and testing of their
computer systems to insure millennium compliance. They we can not give the
Company assurance that their internal systems will be completely free of errors.
Furthermore, they can not give any assurance that all of their 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 their
computer systems or those of their vendors fail to function properly because of
the Year 2000 problem, the results of our operations may materially suffer.

Corporation as of December 31, 1998, and the related statements of earnings,
stockholders' equity and cash flows for the period from the inception of

statements are the responsibility of the company's management. Our
responsibility is to express an opinion of these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Flagstar Capital Corporation
at December 31, 1998, and the results of its operations and its cash flows for

                          FLAGSTAR CAPITAL CORPORATION
 
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- NATURE OF BUSINESS
 
     Flagstar Capital Corporation (the "Company"), is a wholly-owned subsidiary
of Flagstar Bank, FSB (the "Bank") a federally chartered stock savings bank,
which itself is a wholly-owned subsidiary of Flagstar Bancorp, Inc ("Flagstar"),
a financial services holding company. The Company is a Michigan corporation
which commenced operations on February 24, 1998. The Company's primary business
consists of acquiring, holding, and managing residential mortgage loans.
 
     On February 24, 1998, the Company offered to the public and sold 2,000,000
shares of the Company's 8.50% noncumulative preferred stock, Series A, $25
liquidation value per share, providing gross proceeds totaling $50.0 million
(the "Series A Preferred Shares"), and sold to the Bank, 499,900 shares of the
Company's common stock, $1.00 par value providing proceeds totaling $65.5
million (the "Common Stock").
 
     On May 24, 1998, in response to the underwriters exercising their
over-allotment option, the Company issued an additional 300,000 shares of its
Series A Preferred Shares, to the public and 500,000 shares of Common Stock to
the Bank, providing additional gross proceeds of $17.0 million. All shares of
Common Stock are held by the Bank. The Series A Preferred Shares are traded on
the Nasdaq Stock Market(R), under the symbol as "FLGSP".
 
     The Company used the net proceeds raised from the initial public offering
of the Series A Preferred Shares and the sale of the Common Stock to the Bank to
purchase from the Bank the Company's Initial Portfolio of $113.5 million of
residential mortgage loans ("Mortgage Loans") at their estimated fair values.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Mortgage Loans:
 
     Mortgage loans are carried at the principal amount outstanding, net of any
purchase discount and premium. The amortization of the premiums or discounts are
recorded as an adjustment to interest income using a method which approximates
the interest method.
 
     Non-accrual loans are those loans on which the accrual of interest has
ceased. Loans are placed on non-accrual status immediately if, in the opinion of
management, principal or interest is not likely to be paid in accordance with
the terms of the loan agreement, or when principal or interest is past due 90
days or more and collateral, is insufficient to cover principal and interest.
Interest income on non-accrual loans is recognized only to the extent of cash
receipts. However, where there is doubt regarding the ultimate collectibility of
the loan principal, cash receipts, whether designated as principal or interest,
are thereafter applied to reduce the carrying value of the loan. Loans are
restored to accrual status only when interest and principal payments are brought
current and future payments are reasonably assured.
 
     Statement of Financial Accounting Standards No. 114, entitled "Accounting
by Creditors for Impairment of a Loan" ("SFAS 114"), requires that the carrying
value of an impaired loan be based on the present value of expected future cash
flows discounted at the loan's effective interest rate or, as a practical
expedient, at the loan's observable market price, or the fair value or the
collateral, if the loan is collateral dependent. Under SFAS 114, a loan is
considered impaired when, based on current information, it is probable that the
borrower will be unable to pay contractual interest or principal payments as
scheduled in the loan agreement. SFAS 114 applies to all loans except
smaller-balance homogeneous consumer loans, loans carried at fair value or the
lower of cost or fair value, debt securities and leases. The Company will apply
SFAS 114 to non-accrual mortgage loans. In addition, SFAS 114 modifies the
accounting for in-substance foreclosures ("ISF"). A collateralized loan is
considered an ISF and is reclassified to Assets Acquired as Loan Satisfactions
only when the Company has taken physical possession of the collateral regardless
of whether formal foreclosure proceedings have taken place.

<PAGE>   17
                          FLAGSTAR CAPITAL CORPORATION
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Statement of Financial Accounting Standards No. 118, entitled "Accounting
by Creditors for Impairment of a Loan Income Recognition and Disclosure" ("SFAS
118"), permits a creditor to use existing methods for recognizing interest
revenue on impaired loans. The Company recognizes interest income on impaired
loans pursuant to the discussion above for non-accrual loans.
 
     Allowance for loan losses:
 
     An allowance for loan losses is provided when a risk of losses is inherent
in the credit extension process. An allowance is a general allowance and is
based on a periodic review and analysis of the Mortgage Loans. The periodic
analysis will include consideration of such factors as the risk rating of
individual credits, the size and diversity of the portfolio, economic conditions
and market conditions, prior loss experience, results of periodic credit reviews
of the portfolio, and any guarantees provided by the seller of the loans. The
allowance for losses is increased by provisions for losses charged against
income and is reduced by charge-offs, net of recoveries. Charge-offs are
recorded when, in the judgment of management, an extension of credit is deemed
uncollectible, in whole or in part. No allowance has been recorded as of
December 31, 1998
 
     Cash:
 
     The Company considers all short-term, highly liquid investments that are
both readily convertible to cash and have a maturity of generally three months
or less at the time of purchase to be cash equivalents. At December 31, 1998,
the Company's cash was held in the custody of the Bank.
 
     Offering costs:
 
     Costs incurred in connection with the raising of capital through the sale
of preferred stock were recorded as an adjustment to the additional paid in
capital of the Company.
 
     Dividends:
 
          Preferred Stock
 
     Dividends on the Series A Preferred Shares are non cumulative. The stock
was issued on February 24, 1998. Quarterly dividends are payable on the last day
of March, June, September and December at a rate of 8.50% per annum of the
initial liquidation preference ($25.00 per share).
 
          Common Stock
 
     Stockholders are entitled to receive dividends when, and if declared by the
Board of Directors out of funds available after the preferred dividends have
been paid.
 
     Earnings per common share:
 
     Earnings per share is computed by dividing net income after preferred
dividends by the weighted average number of common shares outstanding. There are
no dilutive securities which would require a diluted earnings per share
computation. The Company had 837,902 weighted average shares outstanding during
1998.
 
     Income Taxes:
 
     The Company has elected for Federal income tax purposes, to be treated as a
Real Estate Investment Trust ("REIT") and intends to comply with the provisions
of the Internal Revenue Code of 1986 (the "Code"), as amended. Accordingly, the
Company will not be subject to federal income tax to the extent it distributes
its income to shareholders and as long as certain asset, income and stock
ownership tests are met in

                          FLAGSTAR CAPITAL CORPORATION
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
accordance with the Code. As the Company expects to qualify as a REIT for
federal income tax purposes, no provision for income taxes is included in the
accompanying financial statements.
 
     Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
     Recently Issued Accounting Standards
 
     In June 1997, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"), which requires that an entity
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. The statement is
effective January 1, 2000 for the Company; however, management does not expect
this pronouncement to have a significant impact on the Company's financial
position.
 
     The FASB has issued SFAS No. 134, "Accounting for Mortgage-Backed
Securities Retained after the Securitization of Mortgage Loans Held for Sale by
a Mortgage Banking Enterprise" ("SFAS 134"), The statement requires that an
entity engaged in mortgage banking activities classify any resulting mortgage-
backed securities or other retained interests based on its ability and intent to
sell or hold these investments. The statement is effective for 1999 for the
Company; however, management does not expect this pronouncement to have a
significant impact on the Company's financial position.

     Properties collateralizing Mortgage Loans are geographically disbursed
throughout the United States. As of December 31, 1998, approximately 21.9% of
these properties are located in California (measured by principal balance), and
another 18.2% are located in the state of Michigan. No other state contains more
than 10% of the properties collateralizing these loans.

NOTE 4 -- RELATED PARTY TRANSACTIONS
 
     The Company has entered into an Advisory Agreement (the "Advisory
Agreement") with the Bank (the "Advisor") requiring an annual payment of
$250,000. The Bank provides advice to the Board of Directors and manages the
operations of the Company as defined in the Agreement. The Agreement has an
initial term of five years commencing on February 24, 1998 and automatically
renews for additional five year periods, unless the Company delivers a notice of
non-renewal to the Bank as defined in the Advisory Agreement. Advisory fees
incurred for the period ended December 31, 1998 totaled approximately $213,000.
 
     The Company also entered into a servicing agreement with the Bank for the
servicing of the Mortgage Loans. Pursuant to the servicing agreement, the Bank
performs the servicing for the Mortgage Loans, in accordance with normal
industry practices. The servicing agreement can be terminated without cause upon
a thirty day advance notice given to the Bank. The servicing fee is 0.375% of
the outstanding principal balance of the Mortgage Loans. The servicing fee is
withheld by the Bank from interest income proceeds received on the Mortgage
Loans.
 
NOTE 5 -- FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     Statement of Financial Accounting Standards No. 107, entitled "Disclosures
About Fair Value of Financial Instruments" ("SFAS 107"), requires the Company to
disclose fair value information about financial instruments for which it is
practicable to estimate the value, whether or not such financial instruments are
recognized on the balance sheet. Fair value is defined as the amount at which a
financial instrument could be exchanged in a current transaction between willing
parties, other than in a forced sale or liquidation, and is best evidenced by a
quoted market price, if one exists. The calculation of estimated fair value is
based on market conditions at a specific point in time and may not be reflective
of future fair values.
 
     Certain financial instruments and all non-financial instruments are
excluded from the scope of SFAS 107. Accordingly, the fair value disclosures
required by SFAS 107 provide only a partial estimate of the fair value of the
Company. Fair values among REITs are not comparable due to the wide-range of
limited valuation techniques and numerous estimates which must be made. This
lack of an objective valuation standard introduces a great degree of
subjectivity to these derived or estimated fair values. Therefore, readers are
cautioned in using this information for purposes of evaluating the financial
condition of the Company compared with other REITs.
 
     Mortgage Loans
 
     The fair value of the Company's residential mortgage loans are estimated by
comparing values for similar residential mortgages sold in the secondary market.
 
     At December 31, 1998, the estimated fair value of the Mortgage Loans was
$118,000,000 based on the valuation technique described in the preceding
paragraph.
 
     Assets and liabilities in which fair value approximates carrying value:
 
     The fair values of certain financial assets and liabilities carried at
cost, including cash, accrued interest receivable, loan payments in process- due
from parent, due to parent, and other liabilities are considered to approximate
their respective carrying value due to their short-term nature and negligible
credit losses.

outstanding, certain actions by the Company be approved by a majority of the

Company's Independent Directors. For as long as there are only two Independent

Directors must be approved by both Independent Directors. Additionally, the
audit committee is comprised of the independent directors.

the Series A Preferred Shares, the number of directors constituting the Board of
Directors of the Company will be increased by two at the Company's next annual
meeting and the holders of Series A Preferred Shares, voting together with the
holders of any other outstanding series of Preferred Stock as a single class,
will be entitled to elect the two additional directors to serve on the Company's
Board of Directors. Any member of the Board of Directors elected by holders of
the Company's Preferred Stock will be deemed to be an Independent Director for
