AltaGas Sells Stake in Ikhil Joint Venture to AltaGas Utility Group Inc. for $9 Million

August 01, 2007

CALGARY, ALBERTA--(Marketwire - Aug. 1, 2007) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced it has signed an agreement to sell its 33.3335 percent interest in the Ikhil Joint Venture to AltaGas Utility Group Inc. (Utility Group) for $9 million.

The Ikhil Joint Venture owns two natural gas wells in the Ikhil gas field located approximately 50 kilometres northwest of Inuvik in the Northwest Territories. It is the sole source of supply for Inuvik Gas Limited, one of three natural gas distribution systems owned by Utility Group. The wells produce an average of approximately 1.5 Mmcf/d of sweet dry gas into a field processing facility that cools the gas and delivers it to the town of Inuvik through a 6-inch pipeline, both owned by the Joint Venture.

"The sale of our interest in the Ikhil Joint Venture to AltaGas Utility Group Inc. completes our current divestiture plan of non-core production assets," said David Cornhill, Chairman, President and CEO of the Trust. "The proceeds from the sale of the Trust's interest in the Ikhil Joint Venture and the sale of the Cedar assets will reduce debt by more than $20 million."

No gain or loss is expected to result from the sale, which is effective July 1, 2007 and is subject to normal regulatory approvals.

AltaGas Income Trust owns approximately 27 percent of AltaGas Utility Group Inc., which trades on the Toronto Stock Exchange under the symbol AUI.
