CALGARY, ALBERTA--(Marketwire - Aug. 10, 2010) -

NOT FOR DISTRIBUTION INTO THE UNITED STATES OR TO UNITED STATES WIRE SERVICES

AltaGas Ltd. ("AltaGas") (TSX:ALA) announced today that it will issue 6,000,000 Cumulative Redeemable Five-Year Fixed Rate Reset Preferred Shares, Series A (the "Series A Preferred Shares") at a price of $25 per Series A Preferred Share ("the Offering") for aggregate gross proceeds of $150 million on a bought deal basis with a syndicate of underwriters, led by TD Securities Inc., RBC Capital Markets and CIBC World Markets Inc.

Holders of the Series A Preferred Shares will be entitled to receive a cumulative quarterly fixed dividend for the initial period ending on but excluding September 30, 2015 (the "Initial Period") at an annual rate of 5.00%, payable on the last day of March, June, September and December, as and when declared by the board of directors of AltaGas. The first quarterly dividend payment is payable on December 31, 2010 and shall be $0.4589 per Series A Preferred Share. The dividend rate will reset on September 30, 2015 and every five years thereafter at a rate equal to the sum of the then five-year Government of Canada bond yield plus 2.66%. The Series A Preferred Shares are redeemable by AltaGas, at its option, on September 30, 2015 and on September 30 of every fifth year thereafter.

Holders of Series A Preferred Shares will have the right to convert all or any part of their shares into Cumulative Redeemable Floating Rate Preferred Shares, Series B (the "Series B Preferred Shares"), subject to certain conditions, on September 30, 2015 and on September 30 of every fifth year thereafter. Holders of Series B Preferred Shares will be entitled to receive a cumulative quarterly floating dividend at a rate equal to the sum of the then 90-day Government of Canada Treasury Bill yield plus 2.66%, as and when declared by the board of directors of AltaGas.

The Offering is expected to close on or about August 19, 2010. Net proceeds will be used to reduce outstanding indebtedness under AltaGas' credit facilities, thereby strengthening AltaGas' balance sheet and giving it the financial flexibility to support, among other things, construction activities related to the Forrest Kerr project.

The Series A Preferred Shares will be issued pursuant to a prospectus supplement that will be filed with securities regulatory authorities in Canada under AltaGas' short form base shelf prospectus dated July 15, 2010. An application has been made to list the Series A Preferred Shares on the Toronto Stock Exchange as of the closing date. The Offering is subject to receipt of all necessary regulatory and stock exchange approvals.

The Series A Preferred Shares have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any offer, solicitation or sale of the securities in any state in which such offer, solicitation or sale would be unlawful.
