Enbridge Increases Interest in Nautilus Natural Gas Transmission and Manta Ray Gathering Pipelines in Offshore Gulf of Mexico.

CALGARY, Alberta -- Enbridge Inc. (TSX:ENB) (NYSE:ENB) announced today that it has increased its interest in Neptune Pipeline Company, L.L.C. through the acquisition of Marathon Gas Transmission Inc., a wholly owned subsidiary of Marathon Oil Company. The subsidiary owns a 24.33% interest in Neptune, a holding company that owns the Nautilus gas transmission pipeline and the Manta Ray gathering pipeline system, both in the offshore Gulf of Mexico. The value of the transaction was not disclosed.

As a result of the acquisition of MGTI, Enbridge will hold a 74.33% interest in Neptune with Enterprise Products Partners continuing to hold the remainder.

Nautilus is a 30-inch diameter natural gas transmission pipeline extending 103 miles from a platform in the Ship Shoal Block 207 in the central Gulf of Mexico region to the offshore Garden City area in south central Louisiana, where it interconnects with seven pipelines. Nautilus receives gas supply from the Manta Ray gathering system, which has various receipt points in the central Gulf including the newly constructed Cleopatra Gathering system in which Enbridge has a 22% ownership interest. The recently approved Neptune Gas Lateral will connect to the Cleopatra system. Nautilus has certificated capacity of 600 million cubic feet per day.

Manta Ray consists of 250 miles of pipe ranging from 10-inch to 24-inch diameter and also has 21,100 horsepower of compression located offshore. Capacity on Manta Ray ranges from 800 million cubic feet per day to 1 billion cubic feet per day.

"We are very pleased to increase our interest in both the Nautilus and Manta Ray systems," said Enbridge President & Chief Executive Officer Patrick D. Daniel. "As we noted when we acquired our original interest in the Gulf of Mexico last November, our ownership position in the Enbridge Offshore Pipelines systems provides us with a new growth platform with good upside potential, one that is financially and strategically attractive. While Hurricanes Katrina and Rita have certainly had a significant impact on the people of the Gulf, and on some of the energy infrastructure there, the hurricanes in no way diminish our interest in the future of the Gulf as a source of energy supply for North America. The Gulf of Mexico remains a key region for continental supply growth, and Enbridge plans to be a key player in that development."
