CALGARY, ALBERTA--(Marketwire - July 2, 2010) - AltaGas Income Trust (the "Trust') and AltaGas Ltd. ("AltaGas") are pleased to announce the successful completion of the previously announced plan of arrangement (the "Arrangement") by virtue of which the business of the Trust was reorganized into a dividend paying corporation. Pursuant to the Arrangement, former holders of trust units of the Trust ("Trust Units") and exchangeable limited partnership units of AltaGas Holding Limited Partnership No.1 ("LP #1") are entitled to receive one common share of AltaGas (a "Common Share") for each Trust Unit or exchangeable limited partnership unit. A letter of transmittal pursuant to which holders could transmit their units in exchange for Common Shares was previously delivered to all such holders.

After giving effect to the Arrangement, AltaGas has approximately 81,635,284 Common Shares issued and outstanding.

Within 2 to 3 business days of the Toronto Stock Exchange (the "TSX") confirming receipt of all necessary documentation in connection with the completion of the Arrangement and related matters, the Trust Units will be delisted from the TSX and the Common Shares of AltaGas will be substitutionally listed in their place under the symbol "ALA".

AltaGas has entered into agreements for a new $600 million credit facility with a syndicate of nine banks. The credit facility will be used to retire and replace LP#1's $150 million credit facility and $375 million credit facility that would have matured in August and September 2010 respectively. The facility has a three year term expiring on June 30, 2013.

In July 2010, AltaGas expects to file a new base shelf prospectus to replace the Trust base shelf prospectus as a normal course of business associated with the conversion to a dividend paying corporation.
