AltaGas Income Trust Announces Monthly Distribution

September 12, 2007





CALGARY, ALBERTA--(Marketwire - Sept. 12, 2007) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced that a monthly distribution will be paid on October 15, 2007 to holders of record on September 25, 2007, of Trust Units and limited partnership units that are exchangeable into Trust Units (Exchangeable Units). The amount of the distribution will be $0.175 for each Trust Unit and each Exchangeable Unit.

As previously announced in the Trust's second quarter earnings release, a special distribution of one AltaGas Utility Group Inc. (Utility Group) common share for every 100 Trust units and Exchangeable units of AltaGas held on August 27, 2007 will be made on September 17, 2007. As part of the distribution plan, any Trust unitholder allocated fewer than 50 common shares of Utility Group will receive cash. The cash received by Trust unitholders will be based on the proceeds received on sale of the Utility Group shares. Fractional shares will not be distributed and the number of common shares of Utility Group distributed to each holder will be rounded down to the next whole number of common shares.

Registered holders of record of Trust and Exchangeable units (collectively Unitholders) will receive a share certificate for common shares of Utility Group in the mail. Common shares distributed to non-registered Unitholders will be credited to their investment accounts. Non-resident Unitholders will be subject to withholding taxes as a result of the distribution of Utility Group common shares.

AltaGas has a Premium DistributionTM, Distribution Reinvestment and Optional Unit Purchase Plan (the Plan) for eligible Unitholders of AltaGas Income Trust and AltaGas Holding Limited Partnership No. 1. Information on the Plan is available on the AltaGas website at www.altagas.ca.

Effective with the August 15, 2007 distribution payment, AltaGas has suspended the Premium component of the Plan. The regular component of the DRIP will remain in effect and will continue to support the Trust's financing strategy. In the future, as conditions warrant, the Trust may consider reinstating the Premium DRIP (PDRIP) component based on AltaGas' capital requirements and desire to maintain an efficient capital structure. While the PDRIP component of the plan is suspended, PDRIP participants will continue to receive regular cash distributions.
