CALGARY, Feb. 6 /CNW/ - (AET.UN and ARX - TSX) ARC Energy Trust (the
"Trust") announced today the closing of the previously announced offering of
15,474,400 trust units (including 2,018,400 trust units issued pursuant to the
exercise in full of the over-allotment option granted to the underwriters) at
a price of $16.35 per trust unit for total gross proceeds of approximately
$253 million on a bought deal basis. The syndicate of underwriters was led by
RBC Capital Markets and includes: CIBC World Markets Inc., BMO Capital
Markets, Scotia Capital Inc., TD Securities Inc., FirstEnergy Capital Corp.,
National Bank Financial Inc., Canaccord Capital Corporation, Peters & Co.
Limited, Raymond James Ltd., Thomas Weisel Partners LLC, and Tristone Capital
Inc.
Net proceeds of approximately $240 million will be used to partially
finance the Trust's 2009 capital expenditure program and positions the Trust
to execute on its expansion plans.
The securities offered by the Trust have not been, nor will be,
registered under the United States Securities Act of 1933, as amended, and may
not be offered or sold in the United States or to U.S. persons absent
registration or applicable exemption from the registration requirement of such
Act. This release does not constitute an offer for sale of trust units in the
U.S. and any public offering of trust units in the U.S. will be made by means
of a prospectus.

ARC Energy Trust is one of Canada's largest conventional oil and gas
royalty trusts with an enterprise value of approximately $5 billion. The Trust
expects 2009 oil and gas production to average 64,000 to 65,000 barrels of oil
equivalent per day from six 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.

investors with information regarding ARC, including management's assessment of
ARC's future plans and operations, certain information contained in this

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
