ARC Energy Trust files its Annual Information Form

CALGARY, March 26 /CNW/ - (AET.UN and ARX - TSX) ARC Energy Trust (the "Trust") today filed its Annual Information Form ("AIF") with the Canadian securities regulatory authorities on SEDAR in Canada. The AIF includes the Trust's reserve data and other oil and gas information for the year ended December 31, 2009 as mandated by National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities of the Canadian Securities Administrators. The Trust has also filed its Form 40-F, which includes the annual information form, with the U.S. Securities and Exchange Commission on EDGAR in the United States. Copies of the Trust's Annual Information Form may be obtained on www.sedar.com or on the Trust's website at www.arcenergytrust.com.

ARC Energy Trust is one of Canada's largest conventional oil and gas royalty trusts with an enterprise value of approximately $6.1 billion. The Trust expects 2010 oil and gas production to average 70,500 to 72,500 barrels of oil equivalent per day from seven core areas in western Canada. ARC Energy Trust units trade on the TSX under the symbol AET.UN and ARC Resources exchangeable shares trade under the symbol ARX.

Note: Barrels of oil equivalent (boe) may be misleading, particularly if used in isolation. In accordance with NI 51-101, a boe conversion ratio for natural gas of 6 mcf:1 bbl has been used, which is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

ADVISORY - In the interests of providing ARC unitholders and potential investors with information regarding ARC, including management's assessment of ARC's future plans and operations, certain information contained in this document are forward-looking statements within the meaning of the "safe harbour" provisions of the United States Private Securities Litigation Reform Act of 1995 and the Ontario Securities Commission.

Readers are cautioned not to place undue reliance on forward-looking statements, as there can be no assurance that the plans, intentions or expectations upon which they are based will occur. By their nature, forward-looking statements involve numerous assumptions, known and unknown risks and uncertainties, both general and specific, that contribute to the possibility that the predictions, forecasts, projections and other forward-looking statements will not occur, which may cause ARC's actual performance and financial results in future periods to differ materially from any estimates or projections of future performance or results expressed or implied by such forward-looking statements.
