EXHIBIT 99.85 ------------- - -------------------------------------------------------------------------------- [GRAPHIC OMITTED] [ADVANTAGE LOGO OMITTED] - -------------------------------------------------------------------------------- NEWS RELEASE ADVANTAGE ENERGY INCOME FUND COMPLETES $186 MILLION PROPERTY ACQUISITION September 15, 2004 - -------------------------------------------------------------------------------- CALGARY, ALBERTA - Advantage Energy Income Fund ("Advantage" or "the Fund") (AVN.UN-TSX) announced today the closing of its previously announced acquisition of certain petroleum and natural gas properties and related assets in central Alberta, southern Alberta and southeast Saskatchewan from Anadarko Canada Corporation for total consideration of approximately $186 million (subject to adjustment). The transaction has an effective date of July 1, 2004. The Fund financed the acquisition with a $191 million bought deal financing through a syndicate of underwriters, led by Scotia Capital Inc., which was completed on September 14, 2004. Under the bought deal financing, Advantage issued 3,500,000 Subscription Receipts (the "Subscription Receipts") at a price of $18.80 per Subscription Receipt for gross proceeds of $65,800,000, $75 million aggregate principal amount of 7.50% extendible convertible unsecured subordinated debentures (the "7.50% Debentures") and $50 million aggregate principal amount of 7.75% extendible convertible unsecured subordinated debentures (the "7.75% Debentures"). With the closing of the acquisition, trading in the Subscription Receipts will be halted, and the Subscription Receipts will remain halted until the close of business today, September 15, at which time they will be delisted. Holders of Subscription Receipts will receive one trust unit of the Fund for each Subscription Receipt held, effective at 5:00 p.m. (Calgary time) today, September 15. Advantage's previously-announced cash distribution of $0.23 per trust unit for September 2004 will be paid on October 15 to unitholders of record at the close of business on September 30, 2004. Holders of Subscription Receipts will be entitled as unitholders to receive that distribution, provided they continue to hold their trust units on the record date. With the closing of the acquisition, Advantage's cash distribution to be paid on November 15, 2004 to unitholders of record on October 29, 2004 will be $0.25 per trust unit, being an increase of 8.7% form its previous distribution level. As the Subscription Receipts trade in the "book-entry" system and no individual certificates are issued, holders of Subscription Receipts are not required to take any action in order to receive the trust units to which they are entitled. In addition, with the closing of the acquisition, the maturity dates of the 7.50% Debentures and 7.75% Debentures have been automatically extended from November 1, 2004 in each case to October 1, 2009 and December 1, 2011, respectively. The TSX trading symbols of the 7.50% Debentures and 7.75% Debentures are AVN.DB.D and AVN.DB.C, respectively. Advantage's trust units and outstanding convertible debentures are listed on the TSX under the symbols "AVN.UN", "AVN.DB", "AVN.DB.A", "AVN.DB.B", respectively. Further information with respect to Advantage can be found at its website at www.advantageincome.com. The Subscription Receipts, the 7.50% Debentures and the 7.75% Debentures have not been registered under the U.S. Securities Act and were not offered or sold in the United States. - -------------------------------------------------------------------------------- [GRAPHIC OMITTED] [ADVANTAGE LOGO OMITTED] - -------------------------------------------------------------------------------- THIS PRESS RELEASE IS NOT FOR RELEASE OR DISTRIBUTION IN THE UNITED STATES.
