                         NOTES TO FINANCIAL STATEMENTS

                       THREE MONTHS ENDED MARCH 31, 1998
                                  (UNAUDITED)
                                        

NOTE 1 - THE COMPANY

         Apex Mortgage Capital, Inc. (the "Company") was incorporated in
         Maryland on September 15, 1997. The Company commenced its operations of
         acquiring and managing a portfolio of mortgage assets on December 9,
         1997, upon receipt of the net proceeds from the initial public offering
         of the Company's common stock. The Company uses its equity capital and
         borrowed funds to seek to generate income based on the difference
         between the yield on its mortgage backed securities and the cost of its
         borrowings. The Company is structured for tax purposes as a real estate
         investment trust ("REIT") under the Internal Revenue Code of 1986, as
         amended (the "Code").


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         These interim financial statements are unaudited, internally prepared
         statements, that reflect the necessary interim adjustments which, in
         the opinion of management, are necessary to present a fair statement of
         the results for such interim period. The results of operations for this
         interim period are not indicative of the results for a full fiscal
         year. This filing should be read in conjunction with the Annual Report
         on Form 10-K for the year ended December 31, 1997.

  Cash and Cash Equivalents

         Cash and cash equivalents include cash on hand and highly liquid
         investments with original maturities of three months or less. The
         carrying amount of cash equivalents approximates their fair value.

  Mortgage-Backed Securities

         The Company's mortgage-backed securities consist of securities backed
         by single-family residential real estate mortgage loans. Mortgage-
         backed securities are recorded at cost on the date the assets are
         purchased. Realized gains and losses on sales of the securities are
         determined on a specific identification basis. Substantially all of the
         Company's mortgage-backed securities are expected to qualify as real
         estate assets under the REIT provisions of the Code.

         Interest income is accrued based on the outstanding principal amount of
         the mortgage-backed securities and their contractual terms. Premiums
         and discounts are amortized into interest income over the lives of the
         securities using the effective yield method adjusted for the effects of
         estimated prepayments.

         The Company's policy is to generally classify its mortgage-backed
         securities as available-for-sale. The mortgage-backed securities are
         reported at fair value with unrealized gains and losses excluded from
         earnings and reported as a separate component of equity.

  Hedging Assets

         The Company purchases interest rate cap agreements in order to mitigate
         the impact of rising interest rates on the cost of its short-term
         borrowings. Premiums paid for interest rate cap agreements that are
         matched to the 

                                       7
<PAGE>
 
     Company's short-term borrowings are recorded as hedging assets and are
     amortized over the life of the cap agreements as an adjustment to interest
     expense. Periodic payments receivable under the term of the cap agreements
     are recorded on a accrual basis as reduction of interest expense. In some
     instances, interest rate cap agreements may be entered into based upon
     anticipated future levels of funding. Under these circumstances, to the
     extent the notional amount of interest rate caps exceed the existing level
     of short-term borrowings, the cap agreements are recorded at fair value,
     with unrealized gains or losses recorded as other income or expense, until
     such time as the expected level is achieved.

  Stock Based Compensation

     The Company grants stock options to its directors and officers and to
     certain directors, officers and employees of its investment manager and the
     investment manager itself, as discussed in note 9.  Options granted to
     directors of the Company are accounted for using the intrinsic method, and
     generally no compensation expense is recognized in the statement of
     operations for such options.  Other options are accounted for using the
     fair value method; such options are measured at their fair value when they
     are granted and are recognized as a general and administrative expense
     during the periods when the options vest and the related services are
     performed.

  Federal and State Income Taxes

     The Company will elect to be taxed as a REIT and generally will not be
     subject to federal and state taxes on its income to the extent it
     distributes annually 95% of its predistribution taxable income to
     stockholders and meets certain other asset, income and stock ownership
     tests.  As such, no accrual for income taxes has been included in the
     financial statements.

  Net Income Per Share

     Net income per share is computed in accordance with Statement of Financial
     Accounting Standards ("SFAS") No. 128, Earnings Per Share, and is
     calculated on the basis of the weighted average number of common shares
     outstanding during each period plus the additional dilutive effect of
     common stock equivalents.  The dilutive effect of outstanding stock options
     is calculated using the treasury stock method.

     Stock options that could potentially dilute basic net income per share in
     the future were not included in the computation of diluted net income per
     share because to do so would have been antidilutive for the period
     presented.

  Income Recognition

     Income and expenses are recorded on the accrual basis of accounting.

  Credit Risk

     At March 31, 1998, the Company has limited its exposure to credit losses on
     its portfolio of mortgage-backed securities by purchasing securities that
     are either rated "AAA" by at least one nationally recognized rating agency
     or are issued by the Federal Home Loan Mortgage Corporation ("FHLMC"),
     Fannie Mae (formerly known as the Federal National Mortgage Corporation) or
     the Government National Mortgage Association ("GNMA").  The payment of
     principal and interest on the FHLMC, Fannie Mae and GNMA securities are
     guaranteed by those respective agencies.  At March 31, 1998, all of the
     Company's mortgage-backed securities have an actual or implied "AAA"
     rating.

  Use of Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets 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.

  Comprehensive Income

     During the quarter ended March 31, 1998, the Company adopted SFAS No. 130,
     Reporting Comprehensive Income. This statement establishes standards for
     reporting and display of comprehensive income and its 

                                       8
<PAGE>
 
         components in a full set of general-purpose financial statements.
         Comprehensive income is defined as "the change in equity of a business
         enterprise during a period from transactions and other events and
         circumstances from non-owner sources. It includes all changes in equity
         during a period except those resulting from investments by owners and
         distributions to owners."

</TABLE>

         The contractual final maturity of the mortgage loans supporting the
         mortgage-backed securities is generally 30 years at origination.
         Because of prepayments on the underlying mortgage loans, the actual
         weighted-average maturity is expected to be less.

         The Company did not sell securities or realize any gains or losses in
         the period ended March 31, 1998.

         The adjustable rate mortgage-backed securities are typically subject to
         periodic and lifetime caps that limit the amount an adjustable rate
         mortgage-backed securities' interest rate can change during any given
         period and over the life of the asset. At March 31, 1998, the average
         periodic cap on the adjustable rate mortgage assets was 1.9% per annum
         and the average lifetime cap was equal to 11.4%. At December 31, 1997,
         the average periodic cap on the adjustable rate mortgage assets was
         2.0% per annum and the average lifetime cap was equal to 11.4%.


NOTE 4 - HEDGING ASSETS

         The Company enters into derivative financial instruments for purposes
         of managing interest rate risk, and does not enter into such
         instruments for trading or speculative purposes. The Company's 
         mortgage-backed securities include adjustable rate mortgage products 
         that are funded primarily by short-term borrowings. Because these
         securities are subject to lifetime interest rate caps, the Company
         faces the risk in a rising interest rate environment that yields earned
         on the securities will cease to increase when these cap levels are
         reached, while borrowing costs

                                       9
<PAGE>
 
         continue to rise. In order to mitigate the impact of rising interest
         rates on the cost of its short-term borrowings, the Company has entered
         into interest rate cap agreements.

         Hedging assets consisted of London Interbank Offered Rate ("LIBOR")
         based interest rate cap agreements as follows:

<TABLE>

</TABLE>


         Under these agreements, the Company will receive cash payments to the
         extent of the excess of three month LIBOR over the agreements' contract
         rate times the notional amount.

         The Company expects the level of its short-term borrowings to reach
         approximately the $900,000,000 level of purchased interest rate
         protection during the quarter ended June 30, 1998.


NOTE 5 - REVERSE REPURCHASE AGREEMENTS

         The Company has entered into reverse repurchase agreements to finance
         certain of its mortgage-backed securities. These agreements are secured
         by a portion of the Company's mortgage-backed securities and bear
         interest rates that have historically moved in close relationship to
         LIBOR.

         At March 31, 1998, the Company had outstanding $597,282,000 of reverse
         repurchase agreements with a weighted average current borrowing rate of
         5.52% and a maturity of 6.8 months. The reverse repurchase agreements
         were collateralized by mortgage-backed securities with an estimated
         fair value of $600,829,000.

         At December 31, 1997, the Company had outstanding $87,818,000 of
         reverse repurchase agreements with a weighted average current borrowing
         rate of 5.82% and a maturity of 2.8 months. The reverse repurchase
         agreements were collateralized by mortgage-backed securities with an
         estimated fair value of $90,043,000.

         For the quarter ended March 31, 1998, the average reverse repurchase
         agreement balance was $287,088,000 with a weighted average interest
         cost of 5.59%. The maximum reverse repurchase agreement balance
         outstanding during the quarter ended March 31, 1998 was $597,282,000.



NOTE 6 - FAIR VALUE OF FINANCIAL INSTRUMENTS

         The following table presents the amortized cost and estimated fair
         values of the Company's financial instruments. SFAS No. 107,
         Disclosures About Fair Value of Financial Instruments, defines the fair
         value of a financial instruments as the amount at which the instrument
         could be exchanged in current transaction between willing parties,
         other than in a forced or liquidation sale (dollars in thousands):

         Management bases its fair value estimates for mortgage-backed
         securities and hedging assets primarily on third party bid price
         indications provided by dealers who make markets in these financial
         instruments when such indications are available. However, the fair
         value reported reflects estimates and may not necessarily be indicative
         of the amounts the Company could realize in a current market exchange.
         Cash and cash equivalents, interest receivable and reverse repurchase
         agreements are reflected in the financial statements at their costs,
         which approximates their fair value because of the short-term nature of
         these instruments.


NOTE 7 - STOCK REPURCHASE PROGRAM

         On January 13, 1998, the Company's board of directors authorized a
         program to repurchase up to 750,000 shares of the Company's Common
         Stock. The Company repurchased 197,700 shares of its Common Stock
         pursuant to the program during the quarter ended March 31, 1998. The
         average price per share repurchased was $12.82. The repurchased shares
         are held in treasury at cost.

         An additional 552,300 shares are currently authorized for potential
         repurchase in the future. The Company may continue to repurchase shares
         in the future when market conditions warrant.


NOTE 8 - TRANSACTIONS WITH AFFILIATES

         The Company has entered into a Management Agreement (the "Management
         Agreement") with TCW Investment Management Company (the "Manager"), a
         wholly owned subsidiary of The TCW Group, Inc., under which the Manager
         will manage its day-to-day operations, subject to the direction and
         oversight of the Company's Board of Directors. The Company will pay the
         Manager annual base management compensation, payable monthly in
         arrears, equal to 3/4 of 1% of the average net invested capital as
         further defined in the Management Agreement.

         The Company paid the Manager $173,000 in base management compensation
         in accordance with the terms of the Management Agreement for the
         quarter ended March 31, 1998.

         The Company will also pay the Manager, as incentive compensation, an
         amount equal to 30% of the Net Income of the Company, before incentive
         compensation, in excess of the amount that would produce an annualized
         return on equity equal to the ten-year US Treasury rate plus 1% as
         further defined in the Management Agreement.

         The Company did not accrue for or pay the Manager any incentive
         compensation for the quarter ended March 31, 1998.

         The Company may also grant stock options to directors, officers and key
         employees of the Company, the Manager, its directors, officers and key
         employees.


NOTE 9 - STOCK OPTIONS

         The Company has adopted a stock option plan (the "1997 Stock Option
         Plan") that provides for the grant of both qualified incentive stock
         options that meet the requirements of Section 422 of the Code, and non-
         qualified stock options, stock appreciation rights and dividend
         equivalent rights. Stock options may be granted to directors, officers
         and key employees of the Company, the Manager, its directors, officers
         and key employees.

         The exercise price for any stock option granted under the 1997 Stock
         Option Plan may not be less than 100% of the fair market value of the
         shares of common stock at the time the option is granted. Each option
         must terminate no more than ten years from the date it is granted.
         Subject to anti-dilution provisions for stock splits, stock dividends
         and similar events, the 1997 Stock Option Plan authorizes the grant of
         options to purchase an aggregate 

                                       11
<PAGE>
 
         of up to 10% of the outstanding shares of the Company's common stock,
         but not more than 1,000,000 shares of common stock.

         No options were granted under the 1997 Stock Option Plan during the
         quarter ended March 31, 1998. The Company recognized compensation
         expense of $28,000 during the quarter ended March 31, 1998 for stock
         options previously granted to non-employees.

         If the Company had recorded stock option grants to Company directors at
         fair value and related compensation expense, the pro forma effect on
         the Company's net income and earnings per share would have been as
         follows:

         The fair value of each option grant was estimated to be $1.05 as of the
         grant date using the Black-Scholes option pricing model with the
         following assumptions: dividend yield of 11% per annum; expected
         volatility of 30%; risk free interest rate of 5.82% per annum; and an
         expected life of 10 years.

NOTE 10 - COMMITMENTS AND CONTINGENCIES

          A mortgage company with a similar name recently filed suit against the
          Company demanding that the Company not operate under the name "Apex
          Mortgage Capital." The litigation was instituted by Apex Mortgage
          Corp., a Pennsylvania corporation engaged in the origination, trading
          and servicing of mortgage loans, on November 24, 1997 in the United
          States District Court for the Southern District of New York.

          Subsequent to March 31, 1998, the Company began definitive settlement
          negotiations with the plaintiff to resolve the pending litigation.
          Although there can be no assurance that the matter will be resolved
          favorably in a timely manner, the Company anticipates entering into a
          settlement agreement with the plaintiff that will not have a material
          impact on the financial statements or operations of the Company.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
           RESULTS OF OPERATIONS


Certain information contained in this Quarterly Report on Form 10-Q constitutes
"forward-looking statements" which can be identified by the use of forward-
looking terminology such as "may," "will," "should," "expect," "anticipate,"
"estimate," "intend," "continue," or "believes" or the negatives thereof or
other variations thereon or comparable terminology. Some important factors that
would cause actual results to differ materially from those in any forward-
looking statements include changes in interest rates; domestic and foreign
business, market, financial or legal conditions; differences in the actual
allocation of the assets of the company from those assumed; and the degree to
which assets are hedged and the effectiveness of the hedge, among others. In
addition, the degree of risk is increased by the company's leveraging of its
assets.

                                    GENERAL
                                        
Apex Mortgage Capital, Inc.  (the "Company"), a Maryland corporation, was
formed on September 15, 1997, primarily to acquire United States agency and
other highly rated, single-family real estate mortgage securities and mortgage
loans.  The Company commenced operations on December 9, 1997, upon receipt of
the net proceeds from the initial public offering of the Company's common stock.
The Company's principal executive offices are located at 865 South Figueroa
Street, Suite 1800, Los Angeles, California 90017, and its telephone number is
(213) 244-0440.

The Company uses its equity capital and borrowed funds to seek to generate
income based on the difference between the yield on its mortgage assets and the
cost of its borrowings. The Company will elect to be taxed as a real estate
investment trust ("REIT") under the Internal Revenue Code of 1986, as amended
(the "Code"). The Company will not generally be subject to federal taxes on its
income to the extent that it distributes its net income to its stockholders and
maintains its qualification as a REIT.

The goal of the Company is to be an efficient investor in mortgage assets.  The
Company generally acquires mortgage assets primarily in the secondary mortgage
market through the operational experience and market relationships of TCW
Investment Management Company (the "Manager") and its affiliates.

The day-to-day operations of the Company are managed by the Manager subject to
the direction and oversight of the Company's Board of Directors, a majority of
whom are unaffiliated with the Manager.  The Manager is a wholly-owned
subsidiary of TCW Group Inc. ("TCW").  The Manager was established in 1992 and
TCW began operations in 1971 through one of its affiliates.  The Company's
investment management team consists of selected members of TCW's mortgage-backed
securities group, all of whom have over ten years of experience in raising and
managing mortgage capital.  The Company has elected to be externally managed by
the Manager to take advantage of the existing operational systems, expertise and
economies of scale associated with the Manager's current business operations,
among other reasons.


                                    STRATEGY
                                        
To achieve its business objective and generate dividend yields that provide a
competitive rate of return for its stockholders, the Company's strategy is to:

 .  purchase primarily single-family mortgage assets;

 .  manage the credit risk of its mortgage assets through, among other activities
   (i) carefully selecting mortgage assets to be acquired, (ii) complying with
   the Company's policies with respect to credit risk concentration which, among
   other things, require the Company to maintain a mortgage asset portfolio with
   a weighted average rating generally equivalent to AA (or a comparable rating)
   or better, (iii) actively monitoring the ongoing credit quality and servicing
   of its mortgage assets, and (iv) maintaining appropriate capital levels and
   allowances for possible credit losses;

                                       13
<PAGE>
 
 .  finance purchases of mortgage assets with the net proceeds of equity
   offerings and to utilize leverage to increase potential returns to
   stockholders through borrowings (primarily reverse repurchase agreements)
   with interest rates that will generally reflect changes in short-term market
   interest rates;

 .  seek to structure its borrowings to have interest rate adjustment indices and
   interest rate adjustment periods that, on an aggregate hedged basis,
   generally correspond to the interest rate adjustment periods and weighted
   average lives of its mortgage assets financed with leverage and

 .  utilize interest rate caps, swaps and similar financial instruments to
   mitigate the risk of the cost of its variable-rate liabilities exceeding the
   earnings on its mortgage assets during a period of rising interest rates.

The Company has established the foregoing strategies along with certain
operating policies and procedures to implement them.  However, these strategies
and policies may be modified or waived by the Board of Directors at any time
without the consent or approval of the Company's stockholders.  The ultimate
effect of any such changes is uncertain.


FINANCIAL CONDITION
-------------------

MORTGAGE ASSETS

At March 31, 1998, the Company held $762,953,000 of mortgage assets as compared
to $265,880,000 at December 31, 1997.  The original maturity of a significant
portion of the mortgage assets is approximately thirty years; the actual
maturity is subject to change based on the prepayments of the underlying
mortgage loans.

HEDGING ASSETS

The Company enters into derivative financial instruments for purposes of
managing interest rate risk.  The Company's mortgage-backed securities include
adjustable rate mortgage products that are funded primarily by short-term
borrowings.  Because these securities are subject to lifetime interest rate
caps, the Company faces the risk in a rising interest rate environment that
yields earned on the securities will cease to increase when these cap levels are
reached, while borrowing costs continue to rise.  In order to mitigate the
impact of rising interest rates on the cost of its short-term borrowings, the
Company has entered into interest rate cap agreements.

Hedging assets consisted of London Interbank Offered Rate ("LIBOR") based
interest rate cap agreements as follows:

</TABLE>

Under these agreements, the Company will receive cash payments to the extent of
the excess of three-month LIBOR over the agreements' contract rate times the
notional amount.


LIABILITIES

The Company has entered into reverse repurchase agreements to finance certain of
its mortgage-backed securities.  These agreements are secured by a portion of
the Company's mortgage-backed securities and bear interest rates that have
historically moved in close relationship to LIBOR.

                                       15

At March 31, 1998, the Company had outstanding $597,282,000 of reverse
repurchase agreements with a weighted average current borrowing rate of 5.52%
and a maturity of 6.8 months.  The reverse repurchase agreements were
collateralized by mortgage-backed securities with an estimated fair value of
$600,829,000.

At December 31, 1997, the Company had outstanding $87,818,000 of reverse
repurchase agreements with a weighted average current borrowing rate of 5.82%
and a maturity of 2.8 months.  The reverse repurchase agreements were
collateralized by mortgage-backed securities with an estimated fair value of
$90,043,000.

The Company had $90,637,000 and $90,492,000 of other liabilities at March 31,
1998 and December 31, 1997, respectively, consisting primarily of payables for
unsettled securities.  The Company anticipates settling all other liabilities
within one year by entering into additional reverse repurchase agreements.


RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 1998

For quarter ended March 31, 1998, the Company's net income was $564,000, or
$0.09 per share on both a basic and diluted basis, based on a weighted average
of 6,603,000 shares outstanding.  Net interest income for the period was
$896,000 consisting of interest income on mortgage assets and cash balance less
interest expense on reverse repurchase agreements.  The Company incurred
operating expenses of $332,000 for the quarter consisting of management fees,
audit, tax, legal, printing, insurance and other expenses.

As a REIT, the Company is required to declare dividends amounting to 85% of each
year's taxable income by the end of each calendar year and to have declared
dividends amounting to 95% of its taxable income for each year by the time it
files its applicable tax return.  The Company currently intends to distribute
100% of its taxable net income each year.

The Company anticipates that it will experience differences between its net
income based on generally accepted accounting principles ("GAAP") and its
taxable net income due primarily to differences in the methods used to amortize
purchase premiums and discounts and to the recognition of certain compensation
expenses that are not recognized for tax purposes.

The following table provides a reconciliation between the Company's GAAP net
income and its taxable net income for the three months ended March 31, 1998:

The difference in amortization expense represents a timing difference that will
reverse in future periods.

At March 31, 1998, the Company had distributed $1,180,000 in excess of reported
net income due primarily to the differences between taxable and GAAP net income.

</TABLE>


The effective yield data is computed by dividing the annualized net interest
income or expense into the average daily balance shown.

The Company experienced a negative net interest spread during the quarter ended
March 31, 1998 resulting from faster than expected prepayments on its mortgage
assets.  When actual prepayment experience exceeds expectations, the Company
must amortize its purchase premiums over a shorter time period, resulting in a
reduced yield on the Company's mortgage assets.  For the three months ended
March 31, 1998, the Company's mortgage assets prepaid at an approximate average
annualized constant prepayment rate of 48%.

Although the Company has invested the majority of its assets in adjustable-rate
mortgage securities since its initial public offering in December 1997, the
Company has invested in fixed-rate mortgage assets.  The Company may continue to
purchase fixed-rate mortgage assets in the future should the potential returns
on capital invested, after hedging and all other costs, exceed the returns
available from adjustable-rate mortgage assets or if the purchase of such fixed-
rate mortgage assets would serve to reduce or diversify the risks of the
Company's balance sheet.  If the current high level of prepayment activity in
the adjustable-rate mortgage market continues, the Company may significantly
increase its investments in fixed-rate mortgage assets and correspondingly
reduce its adjustable-rate mortgage holdings.

On January 13, 1998, the Company's board of directors authorized a program to
repurchase up to 750,000 shares of the Company's Common Stock. The Company
repurchased 197,700 shares of its Common Stock pursuant to the program during
the quarter ended March 31, 1998.  The average price per share repurchased was
$12.82.  The repurchased shares are held in treasury at cost.

An additional 552,300 shares are currently authorized for potential repurchase
in the future.  The Company may continue to repurchase shares in the future when
market conditions warrant.


Liquidity and Capital Resources

The Company's primary sources of funds for the quarter ended March 31, 1998
consisted of reverse repurchase agreements totaling $597,282,000.  The Company
expects to continue to borrow funds in the form of reverse repurchase agreements
with maturities that generally correspond to the average reset date or average
life of the Company's mortgage assets after 

                                       17
<PAGE>
 
taking into account certain hedging transactions. At March 31, 1998, the Company
had borrowing arrangements with twelve different investment banking firms.
Increases in short-term interest rates could negatively impact the valuation of
the Company's mortgage assets which could limit the Company's borrowing ability
or cause its lenders to initiate margin calls.

The Company will also rely on the cash flow from operations, primarily monthly
principal and interest payments to be received on the mortgage assets, for
liquidity.

The Company believes that equity capital, combined with the cash flow from
operations and the utilization of borrowings, will be sufficient to enable the
Company to meet anticipated liquidity requirements.  If the Company's cash
resources are at any time insufficient to satisfy the Company's liquidity
requirements, the Company may be required to liquidate mortgage assets or sell
debt or additional equity securities.  If required, the sale of mortgage assets
at prices lower than the carrying value of such assets would result in losses.

The Company may in the future increase its capital resources by making
additional offerings of equity and debt securities, including classes of
preferred stock, common stock, commercial paper, medium-term notes, CMOs and
senior or subordinated notes.  All debt securities, and other borrowings, and
classes of preferred stock will be senior to the common stock in a liquidation
of the Company.  The effect of additional equity offerings may be the dilution
of the equity of stockholders of the Company or the reduction of the price of
shares of the common stock, or both.  The Company is unable to estimate the
amount, timing or nature of additional offerings as they will depend upon market
conditions and other factors.


EFFECTS OF INTEREST RATE CHANGES

The Company invests in adjustable-rate mortgage assets that are typically
subject to periodic and lifetime interest rate caps that limit the amount an
adjustable-rate mortgage asset's interest rate can change during any given
period, as well as the minimum rate payable.  The Company's borrowings will not
be subject to similar restrictions.  Hence, in a period of increasing interest
rates, interest rates on its borrowings could increase without limitation by
caps, while the interest rates on its mortgage assets are generally limited by
caps.  This problem will be magnified to the extent the Company acquires
mortgage assets that are not fully indexed.  Further, some adjustable-rate
mortgage assets may be subject to periodic payment caps that result in some
portion of the interest being deferred and added to the principal outstanding.
This could result in receipt by the Company of less cash income on its
adjustable-rate mortgage assets than is required to pay interest on the related
borrowings.  These factors could lower the Company's net interest income or
cause a net loss during periods of rising interest rates, which would negatively
impact the Company's financial condition, cash flows and results of operations.

The Company intends to fund a substantial portion of its acquisitions of
adjustable-rate mortgage assets with borrowings that have interest rates based
on indices and repricing terms similar to, but of somewhat shorter maturities
than, the interest rate indices and repricing terms of the mortgage assets.
Thus, the Company anticipates that in most cases the interest rate indices and
repricing terms of its mortgage assets and its funding sources will not be
identical, thereby creating an interest rate mismatch between assets and
liabilities.  While the historical spread between relevant short-term interest
rate indices has been relatively stable, there have been periods, especially
during the 1979-1982 and 1994 interest rate environments, when the spread
between such indices was volatile.  During periods of changing interest rates,
such interest rate mismatches could negatively impact the Company's financial
condition, cash flows and results of operations.

Prepayment rates generally increase when prevailing interest rates fall below
the interest rates on existing mortgage assets.  In addition, prepayment rates
generally increase when the difference between long-term and short-term interest
rates declines.  Prepayments of mortgage assets could adversely affect the
Company's results of operations in several ways.  The Company anticipates that a
substantial portion of its adjustable-rate mortgage assets may bear initial
"teaser" interest rates that are lower than their "fully indexed" rates (the
applicable index plus a margin).  In the event that such an adjustable-rate
mortgage asset is prepaid prior to or soon after the time of adjustment to a
fully indexed rate, the Company will have held the mortgage asset while it was
less profitable and lost the opportunity to receive interest at the fully
indexed rate over the expected life of the adjustable-rate mortgage asset.  In
addition, the prepayment of any mortgage asset that had been purchased at a
premium by the Company would result in the immediate write-off of any remaining
capitalized premium amount and consequent reduction of the Company's net
interest income by such amount.  Finally, in the event that the 

                                       18

Company is unable to acquire new mortgage assets to replace the prepaid mortgage
assets, its financial condition, cash flow and results of operations could be
materially adversely affected.

The Company also invests in fixed-rate mortgage assets that are expected to be
funded with short-term borrowings.  During periods of rising interest rates, the
borrowing costs associated with funding such fixed-rate assets are subject to
increase while the income earned on such assets may remain substantially
unchanged.  This would result in a narrowing of the net interest spread between
the related assets and borrowings and may even result in losses. The Company may
enter into derivative transactions seeking to mitigate the negative impact of a
rising interest rate environment. Hedging techniques will be based, in part, on
assumed levels of prepayments of the Company's mortgage assets.  If prepayments
are slower or faster than assumed, the life of the mortgage assets will be
longer or shorter which would reduce the effectiveness of the Company's hedging
techniques and may result in losses on such transactions.  Hedging techniques
involving the use of derivative securities are highly complex and may produce
volatile returns. The hedging activity of the Company will also be limited by
the asset and sources of income requirements applicable to the Company as a
REIT.


PART 2.      OTHER INFORMATION

Item 1.  Legal Proceedings

           A mortgage company with a similar name recently filed suit against
           the Company demanding that the Company not operate under the name
           "Apex Mortgage Capital." The litigation was instituted by Apex
           Mortgage Corp., a Pennsylvania corporation engaged in the
           origination, trading and servicing of mortgage loans, on November 24,
           1997 in the United States District Court for the Southern District of
           New York.

           Subsequent to March 31, 1998, the Company began definitive settlement
           negotiations with the plaintiff to resolve the pending litigation.
           Although there can be no assurance that the matter will be resolved
           favorably in a timely manner, the Company anticipates entering into a
           settlement agreement with the plaintiff that will not have a material
           impact on the financial statements or operations of the Company.
