NEWPORT BEACH, Calif., Sept. 28 /PRNewswire-FirstCall/ -- Joseph R. Tomkinson, Chairman and CEO of Impac Mortgage Holdings, Inc. (NYSE: IMH), or the "Company," a Maryland corporation, being taxed as a Real Estate Investment Trust ("REIT"), is pleased to announce the Board of Directors' approval and declaration of a third quarter dividend of $0.75 per common share. The third quarter dividend will be paid October 15th, 2004 to shareholders of record on October 8th, 2004. The ex-dividend date will be October 6th, 2004, therefore, new shareholders interested in receiving the third quarter dividend must purchase common stock on or before October 5th, 2004.
