Marsulex Press Release dated May 25, 2006

MARSULEX AWARDED CONTRACT FOR SUPPLY OF FLUE GAS DESULFURIZATION SYSTEMS TO LOWER COLORADO RIVER AUTHORITY

TORONTO, May 25, 2006 –Marsulex Inc. (TSX: MLX) announced today that its Power Generation Group has been awarded a contract by the Lower Colorado River Authority (LCRA) to install wet limestone-gypsum flue gas desulfurization (FGD) systems at its Fayette Power Project near La Grange, Texas. Marsulex will supply technology, engineering and FGD equipment for Units 1 and 2, each rated at 600 megawatts, to reduce sulfur dioxide and other air emissions. The contact is valued in excess of US $60 million.

Engineering will commence immediately. Delivery of components is expected to commence in June 2007 and substantial completion is expected in the fourth quarter 2008 for Unit 1 and in the second quarter 2009 for Unit 2.

Marsulex President and Chief Executive Officer, Laurie Tugman, said the win signals the re-entry of Marsulex into the U.S. FGD market.  “With the return in recent years to the view that coal is a viable long-term source of energy in the U.S., the industry is investing in infrastructure, including FGD systems, and demand for these systems is expected to increase.  This project with the LCRA was won in competition against top suppliers in the industry and demonstrates Marsulex’s depth of experience in the industry.”

Marsulex has one of the largest installed bases of wet FGD systems in the world.  In recent years, through its extensive base of licensees, Marsulex has won numerous contracts in China to supply engineering, technology and equipment for wet FGD systems.

Marsulex, which is based in Toronto, Ontario, is a leading provider of industrial services, including environmental compliance solutions for air quality control, processing or handling of industrial by-products or waste streams, and is a producer and marketer of sulphur-based industrial chemicals. The Company’s services and products are provided to a broad base of industrial customers in a wide range of industries. Website:www.marsulex.com.
