Australia Pacific LNG and Sinopec Sign Binding Agreements for LNG Supply and 15% Equity Interest

Australia Pacific LNG and Sinopec International Petroleum Exploration & Production Corporation ("SIPC", a subsidiary 100% owned by Sinopec Group) also signed a Subscription Agreement for SIPC to subscribe for a 15% interest in Australia Pacific LNG thereby reducing ConocoPhillips' and Origin Energy's ownership interest from 50% to 42.5% respectively.

These agreements reflect the commercial terms outlined in the Heads of Agreement signed between Australia Pacific LNG and Sinopec on 25 February 2011. The agreements are subject to approvals by the Chinese Government and in Australia, the Foreign Investment Review Board and are conditional on Australia Pacific LNG reaching a final investment decision.

Origin Energy Managing Director, Mr Grant King said, "Today marks an important milestone in the development of the Australia Pacific LNG project and represents the largest LNG supply agreement in Australian history by annual volume.

"These agreements are testament to the strength of the Australia Pacific LNG project, which is based on Australia's largest coal seam gas reserves and resources together with ConocoPhillips' proven Cascade© LNG technology that is well-suited to a CSG application," Mr King said.

ConocoPhillips' Senior Vice President Exploration and Production, Mr Ryan Lance said, "We welcome Sinopec as an equity partner of Australia Pacific LNG and as a foundation buyer of LNG.

"It is through the large amount of ground work and cooperation by all parties that we have been able to move from a Heads of Agreement to binding agreements in such a short period of time. We reaffirm our target of first LNG cargo to be delivered to Sinopec in 2015.

"Australia Pacific LNG continues to be in discussions with other customers that have the potential to secure off-take agreements," Mr Lance said.

Mr Zhang Yaocang, Vice President of Sinopec Group and Vice Chairman of Sinopec Corporation, indicated that he was pleased to have signed these agreements with Mr Grant King and Mr Ryan Lance, thereby signalling intentions for long-term cooperation between Sinopec, ConocoPhillips and Origin Energy.

"This will help Sinopec diversify its natural gas supply, secure domestic energy supply and meet the rapidly increasing demand of customers in China. Sinopec continues looking for more cooperation opportunities in Australia," Mr Zhang said.

The LNG volumes from Australia Pacific LNG will underpin Sinopec's yet to be constructed Guangxi Receiving Terminal and could also be directed to other LNG import and gasification terminals within China.

"The LNG export agreement builds on Australia Pacific LNG's existing domestic business, which currently provides 40 percent of Queensland's natural gas requirements. The Project stands to create thousands of jobs in regional Queensland and deliver significant opportunities for many local communities in which we operate as well as broader economic benefits," Mr King said.

The agreements were signed today in Brisbane by Zhang Yaocang, Vice President of Sinopec, Grant King, Managing Director of Origin Energy and Ryan Lance, Senior Vice President Exploration and Production of ConocoPhillips. The signing was witnessed by the Minister for Resources, Energy and Tourism, The Hon Martin Ferguson, Queensland Minister for Finance, The Hon Rachel Nolan MP, the Deputy Director General, Oil and Gas China Department, China National Energy Administration, Mr Hu Weiping, Chinese Consul General, Dr Sun Dali.
