                          CAPSTEAD MORTGAGE CORPORATION
                       ANNOUNCES THIRD QUARTER NET INCOME


         DALLAS - October 22, 2003 - Capstead Mortgage Corporation (NYSE: CMO)
today reported net income of $14,779,000, or $0.63 per diluted common share, for
the quarter ended September 30, 2003, compared to $22,751,000, or $1.15 per
diluted common share, for the third quarter of 2002. Operating income, a
non-GAAP financial measure calculated to exclude depreciation on real estate,
gains on asset sales and redemptions of collateralized mortgage obligations
("CMOs"), and the dilutive effects of the Series B preferred shares, was $0.65
per common share for the third quarter of 2003, compared to $0.68 for the second
quarter of 2003 and $1.19 for the third quarter of 2002. A table reconciling
operating income per common share to net income per diluted common share
(calculated in accordance with generally accepted accounting principles
("GAAP")) is included in this release.

THIRD QUARTER RESULTS AND RELATED DISCUSSION

         Operating income declined less during the third quarter than in prior
quarters primarily because of lower borrowing rates and the impact of additions
made to the Company's portfolio of mortgage securities and similar investments.
This portfolio currently consists largely of adjustable-rate mortgage ("ARM")
Fannie Mae, Freddie Mac and Ginnie Mae securities ("Agency Securities").
Financing spreads (the difference between the yields earned on these investments
and the rates charged on related borrowings) declined seven basis points during
the third quarter to 2.69% because of lower portfolio yields, as discussed
below, offset by lower borrowing rates, which benefited from the action taken by
the Federal Reserve on June 25, 2003 to reduce the Federal Funds Rate by 25
basis points. During the third quarter, the Company acquired $163 million of ARM
Agency Securities. In addition, Capstead retained $121 million of fixed-rate
collateral released from financed CMOs that the Company expects will earn
improved financing spreads than when previously financed by CMO bonds. Together,
these additions more than offset $210 million of runoff caused primarily by
mortgage prepayments during the third quarter.

         The overall yield earned on the portfolio averaged 3.82% during the
third quarter of 2003, a decline of 24 basis points from an average yield of
4.06% earned during the previous quarter. Yields on ARM securities fluctuate as
coupon interest rates on the underlying mortgage loans reset to reflect current
interest rates and are expected to continue to decline in the coming quarters.
For example, if interest rates stabilize at current rates, the average yield on
the portfolio could decline approximately 38 basis points by the third quarter
of 2004. Actual yields will depend on portfolio composition as well as
fluctuations in, and market expectations for fluctuations in, interest rates and
levels of mortgage prepayments.




         Average rates on related borrowings were 1.13% during the third quarter
of 2003, a decline of 17 basis points from the second quarter. The Company's
borrowing rates depend on actions by the Federal Reserve to change short-term
interest rates, market expectations of future changes in short-term interest
rates and the extent of changes in financial market liquidity.

         Commenting on Capstead's operations, Andrew F. Jacobs, President and
Chief Executive Officer, said, "Sharp increases in medium and long-term interest
rates in July and August provided us the opportunity to acquire a significant
amount of mortgage assets during the third quarter at attractive prices.
Interest rates declined again in September and although we believe there may
continue to be opportunities to acquire additional mortgage assets at attractive
prices in the near future, such acquisitions may not be sufficient to replace
runoff of our existing portfolio. That being said, portfolio runoff is expected
to begin moderating in the fourth quarter as a higher interest rate environment
has reduced, if not eliminated, the opportunity for homeowners to refinance
their ARM loans into lower rate fixed-rate loans. Additionally, we will continue
to see declines in average yields due to the reset to lower interest rates on
mortgages underlying our ARM securities portfolio. The third quarter common
dividend included the distribution of gains of $0.10 per share from the
redemption of remaining CMO bonds on securitizations previously issued by the
Company. We do not anticipate realizing significant additional gains from CMO
redemptions in the coming quarters."

         Commenting on the Company's investment strategy, Mr. Jacobs added, "We
are currently in the process of reevaluating our investment strategy. While we
fully expect to continue our current strategy of investing in assets that can
provide attractive risk-adjusted returns over the long term with less
sensitivity to changes in interest rates than investments in fixed-rate and
medium-term Agency Securities, we are also examining other real estate-related
opportunities to invest available capital."

         In conclusion, Mr. Jacobs cautioned, "We expect Capstead's operating
income will continue to benefit from excellent financing spreads for the
immediate future; however, opportunities to reinvest capital made available by
maturing investments over the near term may likely not be of the size or have
the return profile capable of generating sufficient returns to offset declining
earnings from our existing portfolios. As a result, quarterly operating income
and common dividends may continue trending lower from current levels."

BOOK VALUE PER COMMON SHARE

         As of September 30, 2003, the Company's book value per common share was
$7.05, a decline of $0.78 during the current quarter and $1.18 since December
31, 2002. Book value declined since year-end because of dividend payments in
excess of quarterly net income (approximately $0.16 per share) and, more
significantly, a reduction in the aggregate unrealized gain on the Company's
investments (most of which are debt securities carried at fair value with
changes in fair value reflected in stockholders' equity) as a result of recent
increases in interest rates and runoff caused by mortgage prepayments. This
unrealized gain can be expected to continue to decline with runoff and to
fluctuate with changes in interest rates and market liquidity, and such changes
will largely be reflected in book value per common share. Book




value will also be affected by other factors, including the level of dividend
distributions and depreciation charges on net-leased real estate; however,
temporary changes in fair values of investments not held in the form of debt or
equity securities generally will not affect book value.

         This document contains "forward-looking statements" (within the meaning
of the Private Securities Litigation Reform Act of 1995) that inherently involve
risks and uncertainties. The Company's actual results and liquidity can differ
materially from those anticipated in these forward-looking statements because of
changes in the level and composition of the Company's investments and unforeseen
factors. As discussed in the Company's filings with the Securities and Exchange
Commission, these factors may include, but are not limited to, changes in
general economic conditions, the availability of suitable investments,
fluctuations in, and market expectations for fluctuations in, interest rates and
levels of mortgage prepayments, deterioration in credit quality and ratings, the
effectiveness of risk management strategies, the impact of leverage, liquidity
of secondary markets and credit markets, increases in costs and other general
competitive factors. Relative to direct investments in real estate, these
factors may include, but are not limited to, lessee performance under lease
agreements, changes in general as well as local economic conditions and real
estate markets, increases in competition and inflationary pressures, changes in
the tax and regulatory environment including zoning and environmental laws,
uninsured losses or losses in excess of insurance limits and the availability of
adequate insurance coverage at reasonable costs.

(a)      Unrealized gains and losses on investments in debt securities
         classified as available-for-sale are recorded in stockholders' equity
         as a component of "Accumulated other comprehensive income." Gains or
         losses are recognized in operating results only if sold. Investments in
         a commercial loan syndication and real estate held for lease are not
         classified as debt securities. Consequently, these assets are not
         subject to mark-to-market accounting and therefore have been excluded
         from this analysis.

(b)      Investments in debt securities classified as held-to-maturity are
         carried on the balance sheet at amortized cost.

(a)  Basis represents the Company's investment before unrealized gains and
     losses. Actual asset yields, runoff rates, borrowing rates and resulting
     financing spread are presented on an annualized basis.

(b)  Projected annualized yields for the fourth quarter 2003 reflect ARM coupon
     resets and lifetime prepayment assumptions as adjusted for expected
     prepayments over the next three months, as of the date of this press
     release. Actual yields realized in future periods will largely depend upon
     (i) changes in portfolio composition, (ii) ARM coupon resets, (iii) actual
     prepayments and (iv) any changes in lifetime prepayment assumptions.

(c)  The Company generally uses its liquidity to pay down borrowings. Return on
     assets is calculated on an annualized basis assuming the use of this
     liquidity to reduce borrowing costs.

*        Capstead reports operating income per common share (a non-GAAP
         financial measure calculated excluding depreciation on real estate,
         gain on asset sales and CMO redemptions, and the dilutive effects of
         the Series B preferred share) under the belief it provides investors
         with a useful supplemental measure of the Company's operating
         performance. Operating income represents a measure of the amount of
         funds generated by operations, which may, at the discretion of
         Capstead's Board of Directors, be used for reinvestment or distributed
         to common stockholders as dividends. Depreciation on real estate,
         although an expense deductible for federal income tax purposes and
         therefore an item that reduces Capstead's REIT distribution
         requirements, is added back to arrive at operating income because it is
         a noncash expense. Gains are excluded because they are considered
         non-operating in nature and the amount and timing of any such gains are
         dependent upon future market conditions. Operating income per common
         share excludes the dilutive effects of the Series B preferred shares
         because it is not economically advantageous to convert these shares at
         the current market prices of both the common shares and Series B
         preferred shares. Consequently, few, if any, actual Series B
         conversions are expected. The Series B preferred shares are considered
         dilutive, for diluted net income per common share purposes only,
         whenever annualized basic net income per common share exceeds $2.21
         (the Series B preferred share annualized dividend of $1.26 divided by
         the current conversion rate of 0.5708).
