Business Wire, May 16, 2008

HOUSTON -- McDermott International, Inc. (NYSE:MDR) ("McDermott") announced today that a subsidiary of The Babcock & Wilcox Company ("B&W") has been awarded a contract valued at more than $70 million to engineer and supply a circulating fluidized bed ("CFB") boiler and related emissions control equipment for Great River Energy's Spiritwood Station - a combined heat and power plant near Spiritwood, North Dakota.

In addition to the CFB boiler, B&W will design and supply Spiritwood's advanced air quality control system, including a pulse jet fabric filter baghouse for particulate control, a spray dry absorber flue gas desulfurization system and a selective non-catalytic reduction system for nitrogen oxides control. The CFB boiler will be designed to burn lignite coal.

"This is the first project B&W has done for Great River Energy and it presents an outstanding opportunity to showcase our well-established CFB and environmental systems technology and meet the needs of our customer," said Brandon Bethards, President of B&W's Power Generation Group.

Engineering is underway at B&W's Barberton, Ohio facility and at Babcock & Wilcox Beijing Company ("BWBC") Ltd., B&W's joint venture in Beijing, China. B&W also will procure certain pressure parts for the boiler from BWBC. Commercial operation of Spiritwood is scheduled to begin in March 2010.
