LETTER OF AWARD FOR LNG PROJECT

Downer EDI Limited (Downer) announced today that the Clough Downer 50:50 joint venture (CDJV) had received a Letter of Award by Fluor for the construction of pipelines, compression facilities and associated infrastructure relating to the Fairview component of the Santos GLNG project, located in the Surat Basin, Queensland.

The Letter of Award relates to a unit rate re-measurable contract valued at around $600 million and involves the construction of over 400 kilometres of gas and water transmission pipelines, two compression facilities and an 800 person camp, as well as the expansion of the existing Fairview compression facilities.

The Chief Executive Officer of Downer, Grant Fenn, said this is another major win and Downer was pleased to be extending its relationship with Clough.

“We have a compelling service offering and an expanding footprint in the growing Oil & Gas sector,” Mr Fenn said.

“This is a significant project award and represents a breakthrough for our recently established Coal Seam Gas division into the expanding Queensland Coal Seam Gas industry. We will utilise resources and expertise from across the company and will work with our partner Downer to deliver the best possible project outcomes to Santos and their partners for this groundbreaking CSG to LNG project,” said Clough’s Chief Executive Officer John Smith.

Construction work is due to commence in September 2011. At peak the project will employ a workforce of 650.
