AltaGas Sells Cedar Energy Partnership

May 30, 2007

CALGARY, ALBERTA--(CCNMatthews - May 30, 2007) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced it has signed an agreement to sell Cedar Energy Partnership (Cedar Energy) to a private energy company (the purchaser) for approximately $12 million effective June 1, 2007. In addition, AltaGas will receive 1 million warrants of the purchaser, each of which will allow AltaGas to subscribe for, and purchase, one fully-paid and non-assessable common share in the capital of the purchaser for a three-year term ending June 1, 2010.

"Over the years AltaGas has accumulated a portfolio of oil and natural gas production assets in connection with larger field gathering and processing facility acquisitions. The assets were held and produced primarily to supply a long-term natural gas sales contract. In late 2006 AltaGas secured third-party supply to this long-term gas commitment, thereby eliminating the need for these production assets," said David Cornhill, Chairman, President and CEO of AltaGas. "The sale of these non-core oil and gas production assets will allow AltaGas to focus more on its core natural gas and power businesses."

The assets owned by Cedar Energy comprise oil and natural gas reserves located throughout Alberta and in the Weyburn area of southeast Saskatchewan. These assets produce approximately 400 barrels of oil equivalent per day, which constitutes approximately 85 percent of the Trust's oil and gas production business. The remainder of the Trust's oil and gas portfolio is an interest in the Ikhil Joint Venture in the Northwest Territories.

The sale of Cedar Energy is expected to modestly increase net income, providing approximately $0.01 per unit on an annual basis. The sale of Cedar Energy will also result in a one-time gain of approximately $1.5 million. The sale is subject to normal regulatory approvals.
