Capstead Mortgage Corporation Declares Dividends on Its Preferred Stocks

The Board of Directors of Capstead Mortgage Corporation (NYSE: CMO) announced today that it will pay the regular quarterly dividend of $0.40 per share on the $1.60 Cumulative Preferred Stock, Series A (NYSE: CMOPRA), and the regular monthly dividend of $0.105 per share on the $1.26 Cumulative Convertible Preferred Stock, Series B (NYSE: CMOPRB). The dividends are payable on December 31, to stockholders of record as of December 17, 2010.

Holders of the Series A and B preferred shares may convert into shares of the Company's common stock at any time; however, currently it is not economically advantageous for the Series B stockholders to do so. Each Series A Preferred share is currently convertible into 1.6479 shares of common stock. Each Series B Preferred share is currently convertible into 0.6366 shares of common stock.

Any conversion requested after one or more preferred record dates within the quarter and on or before the record date for the quarterly common stock dividend will require payment to the Company of all preferred share dividends declared and paid for the corresponding quarter.
