AltaGas Income Trust Announces Trust Unit Offering

May 27, 2004


CALGARY--(CCNMatthews - May 27) - AltaGas Income Trust ("AltaGas") 
(TSX:ALA.UN) announced today that it has filed a preliminary short form 
prospectus with the securities commissions in each of the provinces of Canada 
with respect to the issue of Trust Units. AltaGas intends to raise 
approximately $75 million from the offering which is anticipated to close 
during the week of June 7, 2004. The syndicate of Underwriters is lead by RBC 
Capital Markets and Clarus Securities Inc., and includes BMO Nesbitt Burns 
Inc., Scotia Capital Inc., CIBC World Markets Inc., National Bank Financial 
Inc., Canaccord Capital Corporation and Peters & Co. Limited. AltaGas has 
also granted the Underwriters an over-allotment option to purchase up to an 
additional 10 percent of the issue, exercisable, in whole or in part, within 
30 days following the date of closing.

The net proceeds attributable to the sale of Trust Units will be used to 
reduce bank indebtedness, which may be redrawn and used for general corporate 
purposes including AltaGas' ongoing capital program, the funding of the 
Edmonton Ethane Extraction Plant acquisition announced on March 18, 2004 and 
future acquisitions.

Commenting on the offering, David W. Cornhill, Chairman and Chief Executive 
Officer of AltaGas Ltd., administrator of AltaGas, said, "This unit offering, 
our first since our conversion into an income trust on May 1, 2004, will 
reduce our debt to total capitalization ratio to within our new target range 
of 45 to 50 percent. With a considerably stronger balance sheet and 
predictable, long term cash flows generated by our diversified asset base we 
will continue to be positioned to take advantage of attractive investment 
opportunities as they arise."

AltaGas Income Trust will commence monthly distributions on June 15, 2004 to 
holders of Trust Units and Exchangeable Securities of record on May 25, 2004. 
The amount of the distribution on that date will be $0.15 for each Trust Unit 
and each Exchangeable Security. It is expected that purchasers of Trust Units 
under this offering will be eligible to receive the anticipated July 15, 2004 

Enbridge Inc. (Enbridge) is not participating in this offering of Trust 
Units. Upon completion of the offering Enbridge is expected to hold a fully 
diluted ownership interest of approximately 36 percent.

ECNG Inc. and Energistics Group Inc. for approximately $22.0 million payable 
by way of 993,789 Trust Units issued from AltaGas Income Trust treasury plus 
approximately $1.2 million cash. The transaction is conditional on the
