Shaw Capital Awarded Construction Management Contract for Clean Fuel Project at Marathon Illinois Refinery

BATON ROUGE, La.,--The Shaw Group Inc. (NYSE: SHAW) today announced it has been awarded a capital contract from Marathon Oil Corporation (NYSE: MRO) to provide construction management services for a benzene reduction project at its refinery in Robinson, Ill. Services include management of site construction activities such as contractor selection, safety warning, materials management and project controls. The construction is expected to be completed before the mandated date for reduction of benzene content in gasoline to meet new EPA standards.

The award follows Shaw's earlier project management, engineering and procurement services work for the feasibility and definition phases of the project.

"Shaw has extensive refinery expertise and a strong reputation for helping customers meet clean fuels regulations at their plants," said Lou Pucher, president of Shaw's Energy & Chemicals Group. "We place a priority on understanding key environmental and economic drivers and working closely with our customers to ensure success."

Most recently, Shaw management completed engineering and procurement services for another benzene reduction capital project at Marathon's Catlettsburg, Ky., refinery and a 70,000 barrel per day heavy gas oil hydrocracker unit and 47,000 barrel per day kerosene hydrotreater unit at Marathon's Garyville, La., refinery as part of that plant's recent major expansion project. Last year, Shaw was awarded a maintenance, capital construction, turnaround support and specialty services contract for Marathon's Texas Refining Division.

The undisclosed value of the new contract will be included in Shaw's Energy & Chemicals segment's backlog of unfilled orders in the third quarter of fiscal year 2010.
