Cook Inlet Energy Supply to change name to Macquarie Cook Energy

03 April 2006

The Macquarie Bank Group announced today that effective March 31, 2006, Cook Inlet Energy Supply LLC (“Cook Inlet”) has changed its name to Macquarie Cook Energy, LLC. The name change follows the company’s acquisition by the Macquarie Bank Group on November 1, 2005 and reflects its improved ability to meet the energy needs of customers.

Chairman of Macquarie Cook Energy, Mr Nick O’Kane said, “As Macquarie Cook Energy, we will continue to serve customers under a new name which combines the natural gas market expertise of Cook Inlet with the financial trading expertise and resources of the Macquarie Bank Group.

“The decision to change our name reflects the successful integration of the Cook Inlet platform into the Macquarie Bank Group, building upon Cook Inlet’s expertise that has served the North American gas market over many years. We recognize the brand value that Cook’s reputation has in our industry and its importance as a key strength of our business. Adding the Macquarie name to that foundation underpins the increased services and worldwide network that our company now provides to the industry,” said Mr O’Kane.

Mr Gregory L. Craig, Chief Executive Officer of Macquarie Cook Energy, added, “Importantly, while our name has changed, our commitment to customer service and providing innovative energy solutions has not. We are excited by the opportunities our new name represents and look forward to our continued growth as a leader in our industry.”

Macquarie Cook Energy offers North American natural gas market participants a broad range of short- and long-term energy services and solutions, including asset management and optimization, structured hedging, core needs fulfillment and sophisticated risk management tools.

The terms and conditions of existing agreements between counterparties and Cook Inlet will remain unchanged under Macquarie Cook Energy.
