CALGARY--(CCNMatthews - May 26) - AltaGas Income Trust (the "Trust") 
(TSX:ALA.UN) announced today that a subsidiary of the Trust has executed a 
letter of intent to purchase the business of PremStar Energy Canada Ltd. and

the Trust's operating entities through the provision of physical energy 
supply from the gas field directly to end use customers located primarily in 
Ontario. On a fee for service basis, the PremStar group provides energy 
supply, arranges for transportation services, and supports customers with 
valuable market information

the process. The Trust has assets totaling almost $950 million and a market 
capitalization of approximately $900 million. Its steadily expanding asset 
base today includes natural gas gathering and processing facilities, 
interests in ethane and natural gas liquids extraction plants, and 
transmission pipelines. AltaGas distributes natural gas to Alberta customers 
through AltaGas Utilities Inc., to customers in the Northwest Territories 
through the Ikhil Gas Project and distributes gas in Nova Scotia through its 
interest in Heritage Gas Limited. The Trust provides energy services to 
customers, including marketing of natural gas and natural gas liquids and
