Advantage Energy Income Fund Converted Into Advantage Oil & Gas Ltd.

    CALGARY, July 9 /CNW/ - Advantage Oil & Gas Ltd. ("AOG" or the
"Corporation") (AAV - TSX, AAV - NYSE) announced today that it has completed
the previously announced plan of arrangement (the "Arrangement") involving AOG
and Advantage Energy Income Fund (the "Fund"), pursuant to which, the Fund
converted into the Corporation.
    Unitholders of the Fund voted 91.64% in favour of the Arrangement at the
annual general and special meeting of Fund unitholders held earlier in the
day. In accordance with the terms of the Arrangement, former unitholders of
the Fund who have or will complete the letter of transmittal provided to such
unitholders will receive common shares of AOG on a one-for-one basis. In
addition, as part of the Arrangement, the Fund was dissolved and the
Corporation assumed all of the existing liabilities of the Fund, including the
Fund's convertible debentures which are now convertible debentures of the
Corporation.
    It is anticipated that the Corporation's common shares and convertible
debentures will commence trading on the Toronto Stock Exchange under the new
trading symbols "AAV", "AAV.DB.C", "AAV.DB.D", "AAV.DB.E", and "AAV.DB.G" and
the Corporation's common shares will commence trading on the New York Stock
Exchange under the symbol "AAV" on or about July 14, 2009. The trust units and
convertible debentures of the Fund will be delisted at this time as well.
    At the annual general and special meeting of the Fund, unitholders also
approved the Shareholders' Rights Plan and the Restricted Share Performance
Incentive Plan of AOG.
    At the annual general and special meeting of the Fund, unitholders also
appointed Stephen Balog, Kelly I. Drader, Paul Haggis, John A. Howard, Andy J.
Mah, Ronald A. McIntosh, Sheila O'Brien, Carol D. Pennycook and Steven Sharpe
as directors of the Corporation. Messrs. Gary Bourgeois and Rodger Tourigny
did not stand for re-election as directors and AOG would like to express its
sincere thanks to Messrs. Bourgeois and Tourigny for their dedicated service
to the Corporation and the Fund over the previous eight years.
