CALGARY--(CCNMatthews - Aug. 19) - AltaGas Income Trust (TSE:ALA.UN) today 
announced it has acquired an additional 1,605,000 limited partnership units 
("Units") of Taylor NGL Limited Partnership ("Taylor") from Taylor's equity

made our initial investment in Taylor in 2003. We are very pleased with this 
investment and the opportunity to maintain our ownership interest and 
strengthen our existing business relationship."

Extraction Plant, a facility capable of processing 250 Mmcf/d of natural gas 
and producing 10,400 bbls/d of ethane and natural gas liquids.

of influencing the control or direction of Taylor. AltaGas has no present 
intention of purchasing any additional securities of Taylor, but AltaGas
