ARC Energy Trust is one of Canada's largest conventional oil and gas royalty trusts with an enterprise value of approximately $7.7 billion. The Trust currently produces approximately 83,000 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 Ltd. Series A exchangeable shares trade under the symbol ARX.A.

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.

ARC RESOURCES LTD.

Chief Executive Officer
