                YOU SHOULD NOT RELY ON FORWARD-LOOKING STATEMENTS
                      BECAUSE THEY ARE INHERENTLY UNCERTAIN

Certain statements contained in this renewal annual information form, and in
certain documents incorporated by reference into this renewal annual information
form, constitute forward-looking statements. These statements relate to future
events or our future performance. All statements other than statements of
historical fact may be forward-looking statements. Forward-looking statements
are often, but not always, identified by the use of words such as "seek",
"anticipate", "plan", "continue", "estimate", "expect", "may", "will",
"project", "predict", "potential", "targeting", "intend", "could", "might",
"should", "believe" and similar expressions. These statements involve known and
unknown risks, uncertainties and other factors that may cause actual results or
events to differ materially from those anticipated in such forward-looking
statements. We and AOG believe the expectations reflected in those
forward-looking statements are reasonable but no assurance can be given that
these expectations will prove to be correct and such forward-looking statements
included in, or incorporated by reference into, this renewal annual information
form should not be unduly relied upon. These statements speak only as of the
date of this renewal annual information form or as of the date specified in the
documents incorporated by reference into this renewal annual information form,
as the case may be.

In particular, this renewal annual information form, and the documents
incorporated by reference, contain forward-looking statements pertaining to the
following:

o        the performance characteristics of our assets;
o        oil and natural gas production levels;
o        the size of the oil and natural gas reserves;
o        projections of market prices and costs and the related sensitivities of
         distributions;
o        supply and demand for oil and natural gas;
o        expectations regarding the ability to raise capital and to continually
         add to reserves through acquisitions and development;
o        treatment under governmental regulatory regimes; and
o        capital expenditures programs.

The actual results could differ materially from those anticipated in these
forward-looking statements as a result of the risk factors set forth below and
elsewhere in this renewal annual information form:

o        volatility in market prices for oil and natural gas;
o        liabilities inherent in oil and natural gas operations;
o        uncertainties associated with estimating oil and natural gas reserves;
o        competition for, among other things, capital, acquisitions of reserves,
         undeveloped lands and skilled personnel;
o        incorrect assessments of the value of acquisitions;
o        fluctuation in foreign exchange or interest rates;
o        stock market volatility and market valuations;
o        changes in income tax laws or changes in tax laws and incentive
         programs relating to the oil and gas industry and income trusts;
o        geological, technical, drilling and processing problems and other
         difficulties in producing petroleum reserves; and
o        the other factors discussed under "Risk Factors".


Statements relating to "reserves" or "resources" are deemed to be
forward-looking statements, as they involve the implied assessment, based on
certain estimates and assumptions, that the resources and reserves described can
be profitably produced in the future. Readers are cautioned that the foregoing
lists of factors are not exhaustive. The forward looking statements contained in
this renewal annual information form and the documents incorporated by reference
herein are expressly qualified by this cautionary statement. Neither the Trust,
the Manager, nor AOG undertakes any obligation to publicly update or revise any
forward-looking statements and readers should also carefully consider the
matters discussed under the heading "Risk Factors" in this renewal annual
information form.

                          ADVANTAGE ENERGY INCOME FUND

GENERAL

Advantage Energy Income Fund ("ADVANTAGE", the "TRUST", the "FUND", "US", "WE",
or "OUR" and, where the context requires, also includes the Trust's
subsidiaries) is an entity that provides monthly cash distributions to its
holders ("UNITHOLDERS") of trust units ("TRUST UNITS") of the Trust. Advantage
was created under the laws of the Province of Alberta pursuant to the Trust
Indenture. It is, for Canadian tax purposes, an open-ended mutual fund trust and
is categorized as a "natural resource issuer" for the purposes of Canadian
securities laws. The Trust is administered by the Trustee. The beneficiaries of
the Trust are the Unitholders.

Advantage Oil & Gas Ltd. ("AOG") is an oil and natural gas exploitation and
development company that is wholly-owned by us. It was originally incorporated
in 1979 as Westrex Energy Corp. ("WESTREX"). Through a plan of arrangement under
the BUSINESS CORPORATIONS ACT (Alberta) ("ABCA"), Westrex merged with Search
Energy Inc. on December 31, 1996, and changed its name to Search Energy Corp.
("SEARCH") on January 2, 1997.

Effective May 24, 2001, all of the issued and outstanding common shares of
Search were acquired by 925212 Alberta Ltd. ("ACQUISITIONCO"), a corporation
wholly-owned by us. Search and AcquisitionCo were then amalgamated and continued
as "Search Energy Corp.". On July 26, 2001, Search acquired all of the shares of
Due West Resources Inc. ("DUE WEST"). Effective August 1, 2001, Search and Due
West were amalgamated and continued as "Search Energy Corp.". Effective January
1, 2002, Search acquired a number of natural gas properties located primarily in
southern Alberta formerly administered by Gascan Resources Ltd. On June 26,
2002, Search changed its name to Advantage Oil & Gas Ltd. On November 18, 2002,
AOG acquired all of the issued and outstanding shares of Best Pacific Resources
Ltd. ("BEST PACIFIC"). On December 2, 2003, AOG acquired all of the issued and
outstanding shares of MarkWest Resources Canada Corp. ("MARKWEST"). MarkWest was
amalgamated with AOG effective January 1, 2004. On September 15, 2004, we
indirectly acquired certain petroleum and natural gas properties and related
assets from Anadarko Canada Corporation ("ANADARKO") for approximately
$186,000,000 before closing adjustments. On December 21, 2004, we indirectly
acquired Defiant Energy Corporation ("DEFIANT") by way of the Arrangement (as
defined herein) involving a combination of cash consideration, Trust Units and
Exchangeable Shares of AOG. Effective January 1, 2005, Defiant amalgamated with
AOG.

In accordance with the Management Agreement, Advantage Investment Management
Ltd. (the "MANAGER") has agreed to act as manager of the Trust and AOG. The
Manager is a Canadian-owned energy advisory management corporation, incorporated
on March 19, 2001, pursuant to the provisions of the ABCA.

Our head office, the head office of the Manager and AOG and the registered
office of AOG is located at Suite 3100, 150 - 6th Avenue S.W., Calgary, Alberta,
T2P 3Y7. The registered office of the Manager is located at Suite 1400, 350 -
7th Avenue S.W., Calgary, Alberta, T2P 3N9.

                             [ORGANIZATIONAL CHART]
Notes:

(1)      The Unitholders own 100% of the Trust.
(2)      Cash distributions are made to Unitholders monthly based upon our cash
         flow.
(3)      AOG has two wholly-owned subsidiaries, namely Best Pacific Resources
         (U.S.) Inc. and Spirit Waste Management Inc., both of which
         corporations do not own any material assets.

In accordance with the terms of the Trust Indenture and the Shareholder
Agreement, holders of Trust Units are entitled to direct us as to how to vote in
respect of all matters to be placed before us, including the selection of
directors of AOG, approving AOG's financial statements, and appointing the
auditors of AOG, who shall be the same as our auditors. The Shareholder
Agreement provides that the Unitholders are entitled to elect a majority of the
board of directors of AOG and the Manager has the right to designate two of such
directors.


                       GENERAL DEVELOPMENT OF THE BUSINESS

2002

On January 29, 2002, we issued 2,500,000 Trust Units to the public at a price of
$7.90 per Trust Unit for gross proceeds of $19,750,000. We used the net proceeds
of the issue to complete the acquisition of certain natural gas properties, to
repay bank debt and to fund our 2002 capital expenditure program.

The first annual and special meeting of Unitholders was held on June 25, 2002 at
which, among other things, Unitholders considered and approved the name change
from "Search Energy Corp." to "Advantage Oil & Gas Ltd." and the addition of a
class of non-voting common shares for AOG. On September 10, 2002, we completed
an asset exchange transaction whereby it acquired additional interests in
producing natural gas properties at Vermilion, Alberta in consideration for our
interest in heavy oil properties located in Wainwright, Alberta. The exchange
was structured as a property swap with us neither receiving nor paying any cash
in relation to the transaction.

On September 30, 2002, we announced that it had entered into an acquisition
agreement providing for an offer to purchase, by way of formal take-over bid,
all of the issued and outstanding common shares of Best Pacific, including all
shares issued upon the exercise of outstanding options and warrants, on the
basis of $1.25 cash consideration for each share. We acquired 95% of the shares
and completed the compulsory acquisition of the remaining shares effective
November 21, 2002. The acquisition of Best Pacific had a net purchase price,
after adjustments and fees, of


                                       8


approximately $53.4 million, which amount includes the assumption of
approximately $21.7 million of net debt. The properties owned by Best Pacific
consisted primarily of high working interest natural gas and light oil
properties located in southern Alberta and southeastern Saskatchewan.

On October 18, 2002, in conjunction with the acquisition of Best Pacific, we
closed an offering, on a bought deal basis by way of short form prospectus, of
$55,000,000 aggregate principal amount of debentures, which debentures have a
coupon of 10%, mature on November 1, 2007 and are convertible into Trust Units
at a price of $13.30 per Trust Unit (the "10% DEBENTURES"). Interest is payable
on the 10% Debentures semi-annually and commenced on May 1, 2003. The net
proceeds of the offering were used to fund the acquisition of Best Pacific, to
reduce bank indebtedness and for general corporate purposes.

2003

On July 8, 2003, we completed the issue, by way of short form prospectus, of
$30,000,000 principal amount of 9% convertible unsecured subordinated
debentures, which debentures mature on August 1, 2008 and are convertible into
Trust Units at $17.00 per Trust Unit (the "9% DEBENTURES"). The net proceeds of
the offering were used to fund an expanded capital expenditure program and to
repay debt.

On December 8, 2003, we completed a second issue, by way of short form
prospectus, of 5,100,000 Trust Units at $15.75 per Trust Unit for gross proceeds
of $80,325,000 and $60,000,000 aggregate principal amount of 8 1/4% convertible
unsecured subordinated debentures, which debentures mature on February 1, 2009
and are convertible into Trust Units at $16.50 per Trust Unit (the "8 1/4%
DEBENTURES"). The net proceeds of the offering were used to fund the acquisition
of MarkWest, to reduce amounts outstanding under our credit facility and to fund
drilling and exploitation capital expenditures. In conjunction with the
completion of the financing, we also announced the completion of the MarkWest
acquisition for total cash consideration of $96,800,000 prior to adjustments.

2004

On September 15, 2004, we completed an issue, by way of short form prospectus,
of 3,500,000 Trust Units and $75 million aggregate principal amount of 7.50%
convertible unsecured subordinated debentures (the "7.50% Debentures") and $50
million aggregate principal amount of 7.75% convertible unsecured subordinated
debentures (the "7.75% DEBENTURES") to partially finance the acquisition of
certain petroleum and natural gas properties and related assets from Anadarko.
On December 21, 2004, we closed the Defiant Acquisition in exchange for a
combination of cash consideration, Trust Units and Exchangeable Shares of AOG.
See "Significant Acquisitions" for further details.

On December 21, 2004, we announced the closing of our acquisition of Defiant
(the "DEFIANT ACQUISITION") by way of plan of arrangement (the "ARRANGEMENT")
under section 193 of the ABCA. Pursuant to the Arrangement, shareholders of
Defiant could elect to receive (i) 0.201373 of a Trust Unit for each Defiant
share, (ii) 0.201373 of an AOG exchangeable share for each Defiant share, or
(iii) $2.79889 per Defiant share and the balance of the consideration in Trust
Units as set out in option (i). In addition, Defiant shareholders received one
sixth of one common share of Defiant Resources Corporation, a newly incorporated
exploration company.

The Defiant Acquisition is consistent with our strategy of focusing on natural
gas and light oil properties that provide low risk drilling upside. The
transaction is accretive to our 2005 cash flow and production per unit and
provides us with additional lower risk drilling and recompletion opportunities.
The asset base acquired from Defiant is highly concentrated consisting of three
core areas located in central Alberta in close proximity to our existing
operations and approximately 90% of the production is operated, with four
projects representing 85% of the current production.

SIGNIFICANT ACQUISITIONS

On September 15, 2004, we indirectly acquired certain petroleum and natural gas
properties and related assets from Anadarko Canada Corporation (the "ACQUIRED
ASSETS") for total consideration of approximately $186 million before closing
adjustments (the "ASSET ACQUISITION"). The Asset Acquisition has an effective
date of July 1, 2004. The Business Acquisition Report in respect of the Asset
Acquisition, dated September 30, 2004, was filed in accordance with Part 8 of
National Instrument 51-102 Continuous Disclosure Obligations ("NI 51-102") and
is incorporated herein by reference.

ANTICIPATED CHANGES IN THE BUSINESS

As at the date hereof, we do not anticipate that any material change in our
business shall occur during the balance of the 2005 financial year.

                               RECENT DEVELOPMENTS

On February 9, 2005, we completed an issue, by way of short form prospectus, of
5,250,000 Trust Units at $21.65 per Trust Unit for gross proceeds of
$113,662,500. We initially used the net proceeds of the offering to repay a
portion of our indebtedness under our credit facilities incurred in connection
with, among other things, the Defiant Acquisition. The net proceeds will
ultimately be used for our 2005 capital expenditure program and for general
purposes. As at the closing of the offering, 56,575,489 Trust Units were issued
and outstanding.

ADVANTAGE OIL & GAS LTD.

AOG is actively engaged in the business of oil and gas exploration, development,
acquisition and production in the provinces of Alberta, British Columbia and
Saskatchewan.

We employ a strategy to maintain production from AOG's existing production base
while focusing capital expenditures on low-risk development opportunities. AOG
utilizes financial hedges, when deemed appropriate, to manage and reduce the
volatility in commodity prices. See "Risk Factors". AOG generally sells or farms
out higher risk projects while actively pursuing growth opportunities through
oil and gas property acquisitions, as well as through corporate acquisitions.
AOG targets acquisitions that are accretive to net asset value and that increase
our reserve and production base per Trust Unit outstanding. Acquisitions must
also meet reserve life index criteria and exhibit low risk opportunities to
increase reserves and production. It is currently intended that AOG will finance
acquisitions and investments through bank financing, the issuance of additional
Trust Units from treasury and the issuance of subordinated convertible
debentures, maintaining prudent leverage.

ADVANTAGE INVESTMENT MANAGEMENT LTD.

Pursuant to the Management Agreement, the Manager has agreed to act as manager
of the Trust and AOG. The board of directors of AOG has retained the Manager to
provide comprehensive management services and has delegated certain authority to
the Manager to assist in the administration and regulation of the day-to-day
operations of the Trust and AOG and assist in executive decisions which conform
to the general policies and general principles previously established by the
board of directors. The Manager is entitled to designate two directors to serve
on the board of directors. The Manager also provides executive officers to AOG,
subject to the approval of the board of directors of AOG.

ADDITIONAL INFORMATION RELATING TO RESERVES DATA


UNDEVELOPED RESERVES

Proved and probable undeveloped reserves have been assigned in accordance with
engineering and geological practices as defined under NI 51-101. In general,
undeveloped reserves are planned to be developed over the next two years with
close to 75 percent being completed in 2005. The following tables set forth the
proved undeveloped reserves and the probable undeveloped reserves, each by
product type, attributed to us in the most recent financial year.

SIGNIFICANT FACTORS OR UNCERTAINTIES

High operating costs substantially reduce our netback, which in turn reduces the
amount of cash available for reinvestment in drilling opportunities. This
becomes most relevant during periods of low commodity prices when profits are
more significantly impacted by high costs.

FUTURE DEVELOPMENT COSTS

The following table sets forth development costs deducted in the estimation of
our future net revenue attributable to the reserve categories noted below.

To fund our capital program, including future development costs, we have many
financing alternatives available including partial retention of cash flow from
operations, bank debt financing, issuance of additional Trust Units, and
convertible debentures. We evaluate the appropriate financing alternatives
closely and have made use of all these options dependent on the given investment
situation and the capital markets. We maintain a capital structure that is
similar to our industry peer group and that will maximize the investment return
to Unitholders as compared to the cost of financing. We expect to continue using
all financing alternatives available to continue pursuing our oil and gas
development strategy. The assorted financing instruments have certain inherent
costs which we consider in the economic evaluation of pursuing any development
opportunity.

OTHER OIL AND GAS INFORMATION

OIL AND GAS PROPERTIES

The following is a description of our principal oil and natural gas properties
on production or under development as at January 1, 2005. The term "net", when
used to describe our share of production, means the total of our working
interest share before deduction of royalties owned by others. Reserve amounts
are stated, before deduction of royalties, at December 31, 2004, based upon
forecast cost and price assumptions (gross) as evaluated in the Sproule Report.
Unless otherwise specified, gross and net acres and well count information are
as at January 1, 2005. Information in respect of current production is 2004 exit
production, net to us, except where otherwise indicated.

MEDICINE HAT, ALBERTA

The Medicine Hat (Bowmanton) property is located 20 km northeast of the City of
Medicine Hat in the heart of the southeastern shallow gas area. We have a 100%
working interest in 24 sections of land from which production is taken from all
of the main shallow gas producing formations including the Medicine Hat "A", "C"
and "D" sands, as well as both the Upper and Lower Milk River sands. When the
property was acquired in January 2002 there were 115 wells producing 5.2 MMcf/d
of natural gas. In 2002 and 2003, several recompletions along with an additional
164 wells were drilled. Late in 2003 an additional 57 wells were drilled and
completed in 2004. In 2004 a further 68 wells were drilled and completed. As a
result, in January 2005 this property was producing 21.2 MMcf/d from
approximately 380 wells. Compression capacity was increased in late 2003 by
approximately 10 MMcf/d to accommodate added production from the drilling
programs. No additional compression was added in 2004.

Sproule evaluated our reserves in the area and assigned 65.6 bcf of proved
natural gas reserves and 8.2 bcf of probable reserves. As such, this property is
our largest property on an assigned reserves basis.

NEVIS, ALBERTA

The Nevis property is situated 50 km east of Red Deer. Nevis consists of
approximately 35 sections of land with an average working interest over 75% and
is 90% operated. Natural gas production occurs from numerous shallow depth
horizons including the Edmonton, Belly River and Viking formations. Oil and
natural gas is produced from the slightly deeper reservoirs (1,200 m) of the
Glauconite, Ostacod and Ellerslie formations within the Mannville Group. The
main zone of interest however occurs at 1,600 meters in Devonian aged carbonates
of the Big Valley Member of the Wabamun Formation. In 2004, Wabamun oil was
principally targeted, although gas was also drilled in both the Wabamun and
shallower horizons. Development of the oil is being accomplished by horizontal
drilling into the average 3 meter thick


                                       18


carbonate. Completion of wells is accomplished with selective acid squeezes over
the main porous intervals. Crude quality is exceptional ranging in the most part
between 36 and 42o API. Natural gas is gathered through AOG owned pipelines and
processed at a third party plant. Oil is trucked from single well batteries.

In 2004, 16 horizontal wells and 5 vertical wells were drilled. We currently
have on production, or awaiting imminent tie-in, 14 horizontal wells, which were
all drilled prior to year end of 2004. Production at the end of January 2005 is
2,039 boe/d. An additional 12 wells have been drilled in 2005 to the end of
February. Currently the pool is spaced to allow for 4 wells per section.
Drilling continues at the current spacing; however, the property is being
reviewed for down spacing to 8 wells per section in the second half of 2005. In
addition a study is underway to evaluate the potential waterflood of this
reservoir to increase future recoveries.

The Sproule Report assigns 13 bcf of proven natural gas reserves and 3,314 Mbbls
of proven crude oil and NGL reserves to this property. In addition, 8.4 bcf of
probable natural gas reserves and 2,445 Mbbls of risked probable crude oil and
NGL reserves have been assigned to this property.

BANTRY, ALBERTA

Bantry is located immediately east of the town of Brooks straddling the
TransCanada Highway. The property consists of 86 sections of land ranging
between 50% and 100% working interest. Since the acquisition of this property in
November 2003, 48 (gross) new wells were drilled. Production occurs primarily
from Basal Colorado Formation channel sandstones and various sandstones within
the Bow Island Formation. Drilling depth is shallow with average wells less than
1,000 meters.

Natural gas is gathered into our operated compression and dehydration
facilities. Current net production from this area is approximately 1.6 Mboe/d.
Additional compression capacity was added in the first quarter of 2004 to handle
incremental volumes. The property was last drilled in June 2004 and all
productive wells have been completed and tied-in, however it is being reviewed
for additional drilling with 5 to 6 new wells possible in late 2005 or into
2006.

The Sproule Report assigns 17.1 bcf of proven natural gas reserves and 28 Mbbls
of proven NGL reserves to this property. In addition, 6.9 bcf of probable
natural gas reserves and 11 Mbbls of probable NGL reserves have been assigned to
this property.

CHIP LAKE, ALBERTA

The Chip Lake property is located 125 km west of Edmonton. It produces light oil
(37oAPI) from the Jurassic aged Rock Creek Formation, with some associated
natural gas. This property was acquired in December 2004 with the Defiant
Acquisition. Currently the property produces 250 bbls/d and 300 mcf/d. One well
drilled in the 4th quarter of 2004 has been completed and is being equipped for
production. Additional drilling will occur after regulatory approval of the
facility and waterflood has been received. Defiant had essentially built the oil
facility and water handling facilities but had not received approval to commence
operations. We are currently working through the process with the EUB and expect
to have the property fully operational in the second half of 2005. Production is
however occurring by the use of single well batteries. In addition to the
existing pool, we also acquired some additional undeveloped land with the
Defiant Acquisition and has seismically identified stepout opportunities.

The Sproule Report assigns 1.5 bcf of proven natural gas reserves and 2,300
Mbbls of proven crude oil and NGL reserves to this property. In addition, 1.7
bcf of probable natural gas reserves and 2,441 Mbbls of risked probable crude
oil and NGL reserves have been assigned to this property.

SUNSET-VALLEYVIEW AREA, ALBERTA

This area is located approximately 100 km east of the city of Grande Prairie,
just north of the town of Valleyview. It consists of a group of three main
producing properties: Sunset A, Sunset B, and Valleyview. All three properties
produce from the Triassic Montney Formation, with some production from younger
Cretaceous reservoirs such as the Gething. These properties came with the
Defiant Acquisition in December 2004.


                                       19


SUNSET A- Montney production in these reservoirs is both oil and gas and occurs
from progressively younger stratigraphic traps beneath the Jurassic
unconformity. The youngest sand is preserved the furthest downdip at the Sunset
A pool and production is predominantly oil at 32oAPI. This pool is unitized and
we have a 70% interest in the unit and operate. Development plans include the
drilling of three wells spaced across the unit which will evaluate the viability
of moving the full pool onto a downspaced basis. In addition, a pipeline and
accompanying compression is planned to gather solution gas and transport it to
the Sunset B facility to the north. Gas is currently being flared. Current net
production from the Sunset A unit is 158 bbls/d and 160 mcf/d. The Sunset A pool
was discovered in 1960 and has a long history of stable low decline production.
It is one of our longest life reservoirs.

SUNSET B - Production from this Montney reservoir is predominantly gas although
there is a thin oil column. Oil gravity is light at 33oAPI. Defiant began
operations at Sunset B in mid 2000 and commissioned a sour gas processing plant
and gathering system late that year. The plant and gathering system were
expanded in December 2003, increasing total throughput capacity to 12 MMcf/d.
There is potential to add further compression and upgrades in modular increments
to increase throughput capacity to approximately 20 MMcf/d. Current production
from Sunset B is 3,000 Mcf/d and 100 bbls/d. A small amount of gas is produced
as well from the Cretaceous and Bluesky reservoirs. Sunset B has a long
production history and long reserve life. The original discovery well, Defiant
Sunset 2-14-70-20 W5M, has been on production for 28 years, and has recovered
350 Mboe to date and still produces 12 bbls/d and 85 mcf/d.

VALLEYVIEW - The Sunset B and Valleyview properties are in close proximity to
each other, with the Valleyview property connected to the Sunset B gas
processing plant by a twelve kilometre pipeline where natural gas, NGL and light
oil from both properties are processed. Production at Valleyview is from three
separate sands all older than those at Sunset A or B. Additional drilling
locations exist and seismic re-interpretation is underway to confirm these.
Production at Valleyview is essentially all natural gas with current rates of
5.1 MMcf/d. All wells require fracture stimulation to bring them on production
and cost about $750,000 drilled, completed and tied-in.

For the three properties, Sunset A, Sunset B and Valleyview, the Sproule Report
assigns 25.2 bcf of proven natural gas reserves and 1,537 Mbbls of proven crude
oil and NGL reserves to this property. In addition, 9.8 bcf of probable natural
gas reserves and 1,034 Mbbls of probable crude oil and NGL reserves have been
assigned to this property.

SHOULDICE, ALBERTA

The Shouldice area of southern Alberta is located approximately 45 km southeast
of the city of Calgary. We have an average working interest of more than 85% in
34 sections of land and operate in excess of 90% of our production. Much of this
acreage is downspaced to accommodate additional drilling. In January 2005,
natural gas production of 5,521 MMcf/d was produced on a co-mingled basis from
the Medicine Hat sand with various Belly River Formation sands. In addition to
natural gas, we also produce 42 bbls/d of medium gravity (33(degree) API) crude
oil from the deeper, Mannville Group, Basal Quartz Formation.

During 2003, 20 net wells were added to the existing 70 producers. Both natural
gas and crude oil are produced and gathered through AOG owned facilities of
varying working interests. An additional 4 MMcf/d of new compression capacity
was added in 2004 to handle additional production. Four additional sections of
land have been assembled and the project is under review for additional drilling
later in 2005.

The Sproule Report assigns 12.2 bcf of proven natural gas reserves and 79 Mbbls
of proven crude oil and NGLs to this property. In addition, 2.7 bcf of probable
natural gas reserves and 19 Mbbls of probable crude oil and NGL reserves have
been assigned to this property.

STODDART/NORTH PINE, BRITISH COLUMBIA

The Stoddart/North Pine area lies immediately northwest of the town of Fort St.
John in northeast British Columbia. The area contains multiple producing
horizons, predominantly natural gas from the Permian, Belloy formation and oil
from the Triassic, Charlie Lake formation. Production from this area has very
low decline, is low cost and requires minimal capital expenditures. We own an
interest in 30 producing wells (22 net) in the area. We operate approximately
80% of the natural gas production and have a 40% working interest in the oil
production. The area includes 12,000 gross (9,176


                                       20


net) acres of undeveloped land. Current production from this area is 5 MMcf/d of
natural gas and 140 bbls/d of light oil and NGLs.

Sproule evaluated our proved reserves in the area and assigned 11.1 bcf of
natural gas and 466 Mbbls of crude oil and NGLs. In addition, 4.1 bcf of
probable natural gas reserves and 227 Mbbls of probable crude oil and NGLs
reserves have been assigned to this property.

WAINWRIGHT, ALBERTA

This property, which has varying working interests averaging more than 80% in
approximately 175 sections of land, is located in east central Alberta,
approximately 40 kilometers northwest of Wainwright, Alberta. Current net
production from the property is 5,000 Mcf/d natural gas, 30 bbl/d NGLs and crude
oil. In 2002, we swapped out virtually all of our heavy oil assets in this area
for producing natural gas assets in our adjacent area of Vermilion. Natural gas
production occurs from the Manville Group and Viking Formations at shallow
depths of between 450 and 700 meters. We operate 95% of our production in this
area as well as own and operate a majority interest in an extensive gas
gathering system tied into three Advantage-operated gas compression facilities.
In 2003, 23.3 net wells were drilled for a combination of Viking and Upper
Mannville zones.

Sproule evaluated our proved reserves in the Wainwright area and assigned 9.3
bcf of natural gas. Probable reserves in this area were evaluated by Sproule at
5.6 bcf of natural gas.

BRAZEAU RIVER, ALBERTA

The Brazeau River property is located approximately 50 km west of the town of
Drayton Valley, Alberta. The property produces sour light oil and natural gas
primarily from Devonian aged Nisku pinnacle reefs. The majority of the
production is from a non-operated 50% working interest in the Nisku C, D and E
pools and a 17% working interest in the Nisku A unit. The property was acquired
in the package of assets purchased from Anadarko in 2004. Sweet natural gas is
also produced from eight natural gas wells out of reservoirs in either of the
Cretaceous aged Cardium, Viking or Lower Mannville Formations. Major facility
interests include a 25.7% working interest in the West Pembina Sour Gas Plant
and a 31.6% working interest in the Brazeau River Gas Plant. Current net
production from the property is 4,000 Mcf/d natural gas and 310 bbl/d NGLs and
crude oil.

Sproule evaluated our proved reserves in the Brazeau River area and assigned 3.8
bcf of natural gas and 323 Mbbls of crude oil and NGLs. Probable reserves in
this area were evaluated by Sproule at 2.3 bcf of natural gas and 288 Mbbls of
crude oil and NGLs.

OPEN LAKE, ALBERTA

The Open Lake property is located approximately 35 km north of the town of Rocky
Mountain House, Alberta. The property was acquired in the package of assets
purchased from Anadarko in 2004. We operate and have a 100% working interest in
the Open Lake property. Oil and natural gas production from this property is
multi-zoned from various Cretaceous and Jurassic reservoirs including the Rock
Creek, Ellerslie, Ostracod, Viking, Second White Specks and Belly River
Formations. We have recently re-entered an existing wellbore and completed a
Glauconite zone which has production tested gas rates in excess of 1 MMcf/d. The
well is expected to be tied-in by the end of the 1st quarter 2005. Additional
re-completion opportunities exist in several offsetting wells and we are
actively engaged in re-completing and evaluating these. Net current production
from the property is 2,648 Mcf/d natural gas and 283 bbl/d NGLs and crude oil.

Sproule evaluated our proved reserves in the Open Lake area and assigned 3.4 bcf
of natural gas and 341 Mbbls of crude oil and NGLs. Probable reserves in this
area were evaluated by Sproule at 2.3 bcf of natural gas and 247 Mbbls of crude
oil and NGLs.

We expect that rights to explore, develop and exploit 117,205 net acres of our
undeveloped land holdings will expire by December 31, 2005. The land expirations
do not consider our 2005 exploitation and development program that may result in
extending or eliminating such potential expirations. We closely monitor land
expirations as compared to our development program with the strategy of
minimizing undeveloped land expirations relating to significant identified
opportunities.

ADDITIONAL INFORMATION CONCERNING ABANDONMENT AND RECLAMATION COSTS

We estimate the costs to abandon and reclaim all our shut-in and producing
wells, facilities, gas plants, pipelines, batteries and satellites. No estimate
of salvage value is netted against the estimated cost. Our model for estimating
the amount and timing of future abandonment and reclamation expenditures was
done on an operating area level. Estimated expenditures for each operating area
are based upon Sproule's methodology, which details the cost of abandonment and
reclamation for the major properties that we hold. Each property was assigned an
average cost per well to abandon and reclaim the wells in an area and
abandonment and reclamation costs have been estimated over a 50 year period.

We estimate that we will incur reclamation and abandonment costs on 1,888.1 net
producing and non-producing wells. Costs to abandon and reclaim the producing
wells totals $43.5 million ($10.7 million discounted at 10%) and are included in
the estimate of future net revenue. The additional liability associated with
non-producing wells, pipelines and facilities reclamation costs was estimated to
be $14 million ($2.8 million discounted at 10%), and was not deducted in
estimating future net revenue. Facility reclamation costs are scheduled to be
incurred in the year following the end of the reserve life of our associated
reserves under the assumption that decommissioning of plant/facilities are
mobile assets with a long useful life.

Abandonment and reclamation costs included in the estimate of future net revenue
for the next three years are $0.7 million in 2005, $1.2 million in 2006 and $1.3
million in 2007.

TAX HORIZON

In 2004, we did not pay any income related taxes. However, we did pay capital
taxes that are determined based on the debt and equity levels of the Trust at
the end of a given year. As a result of new legislation in 2003, capital taxes
are to be gradually eliminated over the next four years.

In the Fund's structure, the operating company utilizes available tax pools to
significantly reduce taxable income and makes other required payments to the
Trust transferring both income and associated tax liability to the Unitholders.
Therefore, it is expected, based on current legislation that no cash income
taxes are to be paid by the operating company in the future and it is our intent
to continue with the current arrangement. For the 2004 distributions, 38.33%
were taxable to the Unitholders and 61.67% were deemed a return of capital.

(5)      We do not record royalties and operating expenses on a commodity basis.
         Information in respect of royalties and operating expenses for crude
         oil and NGLs ($/bbl) and natural gas ($/Mcf) has been determined by
         allocating royalties and expenses on an area by area basis based upon
         the relative volume of production of crude oil and NGLs and natural gas
         in those areas.
(6)      Information in respect of netbacks received for crude oil & NGLs
         ($/bbl) and natural gas ($/Mcf) is calculated using operating expense
         figures for crude oil and NGLs ($/bbl) and natural gas ($/Mcf), which
         figures have been estimated. See note (5) above.

DEFINITIONS AND OTHER NOTES

1.       Columns may not add due to rounding.

2.       The crude oil, natural gas liquids and natural gas reserve estimates
         presented in the Sproule Report are based on the definitions and
         guidelines contained in the COGE Handbook. A summary of those
         definitions are set forth below.

     "COGE HANDBOOK" means the Canadian Oil and Gas Evaluation Handbook prepared
     jointly by the Society of Petroleum Evaluation Engineers (Calgary chapter)
     and the Canadian Institute of Mining, Metallurgy & Petroleum;

     "DEVELOPMENT COSTS" means costs incurred to obtain access to reserves and
     to provide facilities for extracting, treating, gathering and storing the
     oil and gas from reserves. More specifically, development costs, including
     applicable operating costs of support equipment and facilities and other
     costs of development activities, are costs incurred to:

         (a)      gain access to and prepare well locations for drilling,
                  including surveying well locations for the purpose of
                  determining specific development drilling sites, clearing
                  ground, draining, road building, and relocating public roads,
                  gas lines and power lines, pumping equipment and wellhead
                  assembly;

         (b)      drill and equip development wells, development type
                  stratigraphic test wells and service wells, including the
                  costs of platforms and of well equipment such as casing,
                  tubing, pumping equipment and wellhead assembly;

         (c)      acquire, construct and install production facilities such as
                  flow lines, separators, treaters, heaters, manifolds,
                  measuring devices and production storage tanks, natural gas
                  cycling and processing plants, and central utility and waste
                  disposal systems; and

         (d)      provide improved recovery systems.

     "EXPLORATION COSTS" means costs incurred in identifying areas that may
     warrant examination and in examining specific areas that are considered to
     have prospects that may contain oil and gas reserves, including costs of
     drilling exploratory wells and exploratory type stratigraphic test wells.
     Exploration costs may be incurred both before acquiring the related
     property and after acquiring the property. Exploration costs, which include
     applicable operating costs of support equipment and facilities and other
     costs of exploration activities, are:


                                       26


         (a)      costs of topographical, geochemical, geological and
                  geophysical studies, rights of access to properties to conduct
                  those studies, and salaries and other expenses of geologists,
                  geophysical crews and others conducting those studies;

         (b)      costs of carrying and retaining unproved properties, such as
                  delay rentals, taxes (other than income and capital taxes) on
                  properties, legal costs for title defence, and the maintenance
                  of land and lease records;

         (c)      dry hole contributions and bottom hole contributions;

         (d)      costs of drilling and equipping exploratory wells; and

         (e)      costs of drilling exploratory type stratigraphic test wells.

     "GROSS" means:

         (a)      in relation to our interest in production and reserves, our
                  "Trust gross reserves", which are our interest (operating and
                  non-operating) share before deduction of royalties and without
                  including any royalty interest of the Trust;

         (b)      in relation to wells, the total number of wells in which we
                  have an interest; and

         (c)      in relation to properties, the total area of properties in
                  which we have an interest.

     "NET" means:

         (a)      in relation to our interest in production and reserves, our
                  interest (operating and non-operating) share after deduction
                  of royalties obligations, plus our royalty interest in
                  production or reserves;

         (b)      in relation to wells, the number of wells obtained by
                  aggregating our working interest in each of our gross wells;
                  and

         (c)      in relation to our interest in a property, the total area in
                  which we have an interest multiplied by the working interest
                  owned by us.

RESERVE CATEGORIES

Reserves are estimated remaining quantities of oil and natural gas and related
substances anticipated to be recoverable from known accumulations, from a given
date forward, based on:

o        analysis of drilling, geological, geophysical and engineering data;

o        the use of established technology; and

o        specified economic conditions.

Reserves are classified according to the degree of certainty associated with the
estimates.

         (a)      PROVED RESERVES are those reserves that can be estimated with
                  a high degree of certainty to be recoverable. It is likely
                  that the actual remaining quantities recovered will exceed the
                  estimated proved reserves.

         (b)      PROBABLE RESERVES are those additional reserves that are less
                  certain to be recovered than proved reserves. It is equally
                  likely that the actual remaining quantities recovered will be
                  greater or less than the sum of the estimated proved plus
                  probable reserves.

Other criteria that must also be met for the categorization of reserves are
provided in the COGE Handbook.


                                       27


Each of the reserve categories (proved and probable) may be divided into
developed and undeveloped categories:

         (a)      DEVELOPED RESERVES are those reserves that are expected to be
                  recovered from existing wells and installed facilities or, if
                  facilities have not been installed, that would involve a low
                  expenditure (for example, when compared to the cost of
                  drilling a well) to put the reserves on production. The
                  developed category may be subdivided into producing and
                  non-producing.

                  (i)      DEVELOPED PRODUCING RESERVES are those reserves that
                           are expected to be recovered from completion
                           intervals open at the time of the estimate. These
                           reserves may be currently producing or, if shut-in,
                           they must have previously been on production, and the
                           date of resumption of production must be known with
                           reasonable certainly.

                  (ii)     DEVELOPED NON-PRODUCING RESERVES are those reserves
                           that either have not been on production, or have
                           previously been on production, but are shut-in, and
                           the date of resumption of production is unknown.

         (b)      UNDEVELOPED RESERVES are those reserves expected to be
                  recovered from known accumulations where a significant
                  expenditure (for example, when compared to the cost of
                  drilling a well) is required to render them capable of
                  production. They must fully meet the requirements of the
                  reserves classification (proved, probable) to which they are
                  assigned.

LEVELS OF CERTAINTY FOR REPORTED RESERVES

The qualitative certainty levels referred to in the definitions above are
applicable to individual reserve entities (which refers to the lowest level at
which reserves calculations are performed) and to reported reserves (which
refers to the highest level sum of individual entity estimates for which
reserves are presented). Reported reserves should target the following levels of
certainty under a specific set of economic conditions:

         (a)      at least a 90 percent probability that the quantities actually
                  recovered will equal or exceed the estimated proved reserves;
                  and

         (b)      at least a 50 percent probability that the quantities actually
                  recovered will equal or exceed the sum of the estimated proved
                  plus probable reserves.

Additional clarification of certainty levels associated with reserves estimates
and the effect of aggregation is provided in the COGE Handbook.

MARKETING

Our crude oil and natural gas production is primarily sold through marketing
companies at current market prices. These contracts are generally for less than
a year and are cancellable on 30 days notice. Approximately 23% of our natural
gas production is sold to aggregators who accumulate production from various
producers and market the gas on behalf of the group. Such contracts are reserve
specific and continue for the life of production from the specified reserves.

CYCLICAL AND SEASONAL IMPACT OF INDUSTRY

Our operational results and financial condition will be dependent on the prices
received for oil and natural gas production. Oil and natural gas prices have
fluctuated widely during recent years and are determined by supply and demand
factors, including weather and general economic conditions, as well as
conditions in other oil and natural gas regions. Any decline in oil and natural
gas prices could have an adverse effect on our financial condition. We mitigate
such price risk through closely monitoring the various commodity markets and
establishing hedging programs, as deemed necessary, to provide stability to
Unitholders' cash distributions and lock-in high netbacks on production volumes.
See "Other Oil and Gas Information - Forward Contracts" for our current hedging
program.


                                       28


RENEGOTIATION OR TERMINATION OF CONTRACTS

As at the date hereof, we do not anticipate that any aspect of our business will
be materially affected in the remainder of 2005 by the renegotiation or
termination of contracts or subcontracts.

ENVIRONMENTAL CONSIDERATIONS

We are pro-active in our approach to environment concerns. Procedures are in
place to ensure that the utmost care is taken in the day-to-day management of
our oil and gas properties. All government regulations and procedures are
followed in strict adherence to the law. We believe in well abandonment and site
restoration in a timely manner to ensure minimal damage to the environment and
lower overall costs to us.

COMPETITIVE CONDITIONS

We are a member of the petroleum industry, which is highly competitive at all
levels. We compete with other companies for all of our business inputs,
including exploitation and development prospects, access to commodity markets,
acquisition opportunities, available capital and staffing.

We strive to be competitive by maintaining a strong financial condition and by
utilizing current technologies to enhance exploitation, development and
operational activities.

HUMAN RESOURCES

As at December 31, 2004, we employ 77 full-time employees, all of which are
located in the head office and 15 consultants.

         ADDITIONAL INFORMATION RESPECTING ADVANTAGE ENERGY INCOME FUND


TRUST UNITS

An unlimited number of Trust Units may be created and issued pursuant to the
Trust Indenture. As at December 31, 2004, 49,674,783 Trust Units were issued and
outstanding. Each Trust Unit represents an equal fractional undivided beneficial
interest in any distributions from, and in any net assets of, the Trust in the
event of termination or winding up of the Trust. The beneficial interests in the
Trust are divided into two classes, as follows: (i) Trust Units, which are
entitled to the rights, subject to limitations, restrictions and conditions set
out in the Trust Indenture, as summarized herein and (ii) "special voting
units", which shall be issued to a trustee and which are entitled to such number
of votes at meetings of Unitholders as is equal to the number of Trust Units
reserved for issuance that such special voting units represent, such number of
votes and any other rights or limitations to be prescribed by AOG's board of
directors. As at the date hereof there is one special voting unit outstanding.
The special voting unit gives AOG the flexibility to acquire the securities of
another issuer in consideration for securities which are ultimately exchangeable
for Trust Units. All Trust Units are of the same class with equal rights and
privileges. Each Trust Unit is transferable, entitles the holder thereof to
participate equally in distributions, including the distributions of net income
and net realized capital gains of the Trust, and distributions on liquidation,
is fully paid and non assessable and entitles the holder thereof to one vote at
all meetings of Unitholders for each Trust Unit held.

The Trust Units do not represent a traditional investment and should not be
viewed by investors as "shares" in either AOG or the Trust. Corporate law does
not govern the Trust and the rights of Unitholders. As holders of Trust Units in
the Trust, the Unitholders will not have the statutory rights normally
associated with ownership of shares of a corporation including, for example, the
right to bring "oppression" or "derivative" actions. The rights of Unitholders
are specifically set forth in the Trust Indenture. In addition, trusts are not
defined as recognized entities within the definitions of legislation such as the
Bankruptcy and Insolvency Act (Canada) and the Companies' Creditors Arrangement
Act (Canada). As a result, in the event of an insolvency or restructuring, a
Unitholder's position as such may be quite different than that of a shareholder
of a corporation.


                                       29


The price per Trust Unit is a function of anticipated distributable income from
AOG and the combined ability of AOG's board of directors and the Manager to
effect long term growth in the value of the Trust. The market price of the Trust
Units will be sensitive to a variety of market conditions including, but not
limited to, interest rates, commodity prices and our ability to acquire
additional assets. Changes in market conditions may adversely affect the trading
price of the Trust Units.

A return on an investment in the Trust is not comparable to the return on an
investment in a fixed-income security. The recovery of an initial investment in
the Trust is at risk, and the anticipated return on such investment is based on
many performance assumptions. Although the Trust intends to make distributions
of its available cash to holders of Trust Units, these cash distributions may be
reduced or suspended. The actual amount distributed will depend on numerous
factors including: the financial performance of AOG, debt obligations, working
capital requirements and future capital requirements. In addition, the market
value of the Trust Units may decline if the Trust's cash distributions decline
in the future, and that market value decline may be material.

It is important for an investor to consider the particular risk factors that may
affect the industry in which it is investing, and therefore the stability of the
distributions that it receives. See "Risk Factors".

The after-tax return from an investment in Trust Units to Unitholders subject to
Canadian income tax can be made up of both a return on capital and a return of
capital. That composition may change over time, thus affecting an investor's
after-tax return. Returns on capital are generally taxed as ordinary income in
the hands of a Unitholder. Returns of capital are generally tax-deferred (and
reduce the Unitholder's cost base in the Trust Unit for tax purposes).

EXCHANGEABLE SHARES

As at December 31, 2004, AOG had 1,450,030 Exchangeable Shares outstanding. The
Exchangeable Shares were issued in connection with our acquisition of Defiant.
Each Exchangeable Share is exchangeable for Trust Units at any time (subject to
the provisions of the Voting and Exchange Trust Agreement), on the basis of the
applicable exchange ratio in effect at that time, in accordance with the share
provisions applicable to such shares and the terms and provisions of the Voting
and Exchange Trust Agreement. The exchange ratio was initially equal to one upon
issuance of the Exchangeable Shares and will increase on each date that a
distribution is paid by us on the Trust Units. The exchange ratio will decrease
on each record date for the payment of dividends on the Exchangeable Shares. The
holders of Exchangeable Shares are not entitled to any vote at meetings of
shareholders of AOG but are, through the Special Voting Unit of Advantage held
by the Trustee as trustee under the Voting and Exchange Trust Agreement,
entitled to vote (on the basis of the number of votes equal to the number of
Trust Units into which the Exchangeable Shares are then exchangeable) with the
holders of Trust Units as a class. In addition, holders are provided with all
information sent by us to Unitholders. Holders of Exchangeable Shares will be
entitled to receive, as and when declared by the board of directors of AOG in
its sole discretion from time to time, such cash dividends as may be declared
thereon by the board of directors. It is not anticipated that dividends will be
declared or paid on the Exchangeable Shares. The Exchangeable Shares will be
redeemable by AOG, in certain circumstances, and will be retractable by holders
of Exchangeable Shares, in certain circumstances. Exchangeable Shares not
previously redeemed or retracted will be redeemed by AOG or purchased by us on
January 15, 2008.

TRUST UNITHOLDER LIMITED LIABILITY

The Trust Indenture provides that no Trust Unitholder will be subject to any
liability in connection with the Trust or its obligations and affairs and, in
the event that a court determines our Unitholders are subject to any such
liabilities, the liabilities will be enforceable only against, and will be
satisfied only out of the Trust Unitholder's share of our assets. Pursuant to
the Trust Indenture, we will indemnify and hold harmless each Trust Unitholder
from any cost, damages, liabilities, expenses, charges and losses suffered by a
Trust Unitholder resulting from or arising out of such Trust Unitholder not
having such limited liability.

The Trust Indenture provides that all written instruments signed by or on behalf
of us must contain a provision to the effect that such obligation will not be
binding upon our Unitholders personally. Notwithstanding the terms of the Trust
Indenture, Unitholders may not be protected from our liabilities to the same
extent as a shareholder is protected from the liabilities of a corporation.
Personal liability may also arise in respect of claims against the Trust (to the
extent that claims are not satisfied by the Trust Fund) that do not arise under
contracts, including claims in tort, claims for taxes and


                                       30


possibly certain other statutory liabilities. The possibility of any personal
liability to Unitholders of this nature arising is considered unlikely in view
of the fact that our sole business activity is to hold securities, and all of
the business operations currently carried on by AOG will be carried on by a
corporate entity, directly or indirectly.

Our business and that of our wholly-owned subsidiary, AOG, is conducted, upon
the advice of counsel, in such a way and in such jurisdictions as to avoid as
far as possible any material risk of liability to our Unitholders for claims
against us, including obtaining appropriate insurance, where available, for the
operations of AOG and having written agreements, signed by or on our behalf,
include a provision that such obligations are not binding upon our Unitholders
personally.

ISSUANCE OF TRUST UNITS

The Trust Indenture provides that Trust Units or rights to acquire Trust Units
may be issued at the times, to the persons, for the consideration, and on the
terms and conditions that the board of directors of AOG determines. The Trust
Indenture also provides that immediately after any PRO RATA distribution of
Trust Units to all Unitholders in satisfaction of any non-cash distribution, the
number of outstanding Trust Units will be consolidated such that each Trust
Unitholder will hold, after the consolidation, the same number of Trust Units as
the Trust Unitholder held before the non-cash distribution. In this case, each
certificate representing a number of Trust Units prior to the non-cash
distribution is deemed to represent the same number of Trust Units after the
non-cash distribution and the consolidation.

CASH DISTRIBUTIONS

The amount of cash to be distributed annually per Trust Unit shall be equal to a
PRO RATA share of interest on the Notes, royalty income from the Royalty,
dividends on or in respect of shares of AOG received by us and income from the
Permitted Investments; less: (i) our administrative expenses and other
obligations; and (ii) amounts which may be paid by us in connection with any
cash redemptions of Trust Units. AOG may apply some or all of its cash flow to
capital expenditures to develop the Oil and Natural Gas Properties of AOG or to
acquire additional Oil and Natural Gas Properties prior to making any
distributions to us in the form of principal repayments on the Notes or
dividends on the Common Shares, Non-Voting Shares or Preferred Shares. If, on
any Distribution Record Date, the Trustee determines that we do not have cash in
an amount sufficient to pay the full distribution to be made on such
Distribution Record Date in cash or if any cash distribution should be contrary
to any subordination agreement, the distribution payable to Unitholders on such
Distribution Record Date may, at the option of the Trustee, include a
distribution of additional Trust Units having an equal value to the cash
shortfall. Trust Units will be issued pursuant to exemptions under applicable
securities laws, discretionary exemptions granted by applicable securities
regulatory authorities or a prospectus or similar filing.

We derive interest income from our holdings of the Notes. It is expected that
our income will generally be limited to: (i) the interest received on the
principal amount of the Notes; (ii) royalty income received on the Royalty; and
(iii) dividends (if any) received on shares of AOG. See "Additional Information
Respecting Advantage Oil & Gas Ltd. - Notes".

The board of directors of AOG intends for the Trust to make monthly cash
distributions. Cash distributions will be made monthly to the Unitholders of
record on the last day of each month (unless such day is not a Business Day, in
which case the date of record shall be the next following Business Day) and
shall be payable on the 15th day of each month or, if such day is not a Business
Day, the following Business Day or such other date as determined from time to
time by the Trustee.

REDEMPTION RIGHT

Trust Units are redeemable at any time on demand by the holders thereof upon
delivery to us of the certificate or certificates representing such Trust Units,
accompanied by a duly completed and properly executed notice requesting
redemption. Upon our receipt of the redemption request, all rights to and under
the Trust Units tendered for redemption shall be surrendered and the holder
thereof shall be entitled to receive a price per Trust Unit (the "REDEMPTION
PRICE") equal to the lesser of: (i) 85% of the "market price" of the Trust Units
on the principal market on which the Trust Units are quoted for trading during
the 10 trading-day period commencing immediately after the date on which the
Trust Units are surrendered for redemption (the "REDEMPTION DATE"); and (ii) the
"closing market price" on the principal market on which the Trust Units are
quoted for trading on the Redemption Date.


                                       31


For the purposes of this calculation, "market price" is an amount equal to the
simple average of the closing price of the Trust Units for each of the trading
days on which there was a closing price, provided that, if the applicable
exchange or market does not provide a closing price but only provides the
highest and lowest prices of the Trust Units traded on a particular day, the
market price shall be an amount equal to the simple average of the highest and
lowest prices for each of the trading days on which there was a trade, and
provided further that if there was trading on the applicable exchange or market
for fewer than five of the 10 trading days, the market price shall be the simple
average of the following prices established for each of the 10 trading days: the
average of the last bid and last ask prices for each day on which there was no
trading; the closing price of the Trust Units for each day that there was
trading if the exchange or market provides a closing price; and the average of
the highest and lowest prices of the Trust Units for each day that there was
trading, if the market provides only the highest and lowest prices of Trust
Units traded on a particular day. The "closing market price" shall be: an amount
equal to the closing price of the Trust Units if there was a trade on the date;
an amount equal to the average of the highest and lowest prices of the Trust
Units if there was trading and the exchange or other market provides only the
highest and lowest prices of Trust Units traded on a particular day; and the
average of the last bid and last ask prices if there was no trading on the date.

The aggregate Redemption Price payable by us in respect of any Trust Units
surrendered for redemption during any calendar month shall be satisfied by way
of a cash payment on or before the last day of the following month; provided
that the entitlement of Unitholders to receive cash upon the redemption of their
Trust Units is subject to the limitations that: (i) the total amount payable by
us in respect of such Trust Units and all other Trust Units tendered for
redemption in the same calendar month shall not exceed $100,000 (provided that
the Trustee may, in its sole discretion, waive such limitation in respect of any
calendar month); (ii) at the time such Trust Units are tendered for redemption
the outstanding Trust Units shall be listed for trading on a stock exchange or
traded or quoted on any other market which the Trustee considers, in its sole
discretion, provides representative fair market value prices for the Trust
Units; and (iii) the normal trading of Trust Units is not suspended or halted on
any stock exchange on which the Trust Units are listed (or, if not listed on a
stock exchange, on any market on which the Trust Units are quoted for trading)
on the Redemption Date or for more than five trading days during the 10-day
trading period commencing immediately after the Redemption Date.

If a Trust Unitholder is not entitled to receive cash upon the redemption of
Trust Units as a result of the foregoing limitations, then the Redemption Price
for such Trust Units shall be the Fair Market Value thereof (as defined in the
Trust Indenture), as determined by the Trustee in the circumstances described in
subparagraphs (ii) and (iii) above, and shall, subject to any applicable
regulatory approvals, be paid and satisfied by way of distribution IN SPECIE of
a PRO RATA number of Long Term Notes (in a minimum amount of $100.00 and
integral multiples of $1.00), from time to time outstanding (i.e., in a
principal amount equal to the Redemption Price). No fractional Long Term Notes
will be distributed and where the number of Long Term Notes to be received by a
Trust Unitholder includes a fraction, such number shall be rounded to the next
lowest whole number. We shall be entitled to all interest paid, or accrued and
unpaid, on the Long Term Notes on or before the date of the distribution IN
SPECIE. If we do not hold Long Term Notes having a sufficient principal amount
outstanding to effect such payment, we will be entitled to create and, subject
to any applicable regulatory approvals, issue in satisfaction of the Redemption
Price our own debt securities (the "REDEMPTION NOTES") having terms and
conditions substantially the same as the Long Term Notes, and with recourse of
the holder limited to our assets. Holders of such Long Term Notes and Redemption
Notes will be required to acknowledge that they are subject to the subordination
agreements described below under the heading "Additional Information Regarding
Advantage Oil & Gas Ltd. - Notes". Long Term Notes and Redemption Notes may not
be qualified investments for trusts governed by registered retirement savings
plans, registered retirement income funds and deferred profit sharing plans if
the Trust ceases to qualify as a mutual fund trust.

It is anticipated that the redemption right will not be the primary mechanism
for holders of Trust Units to dispose of their Trust Units. Long Term Notes or
Redemption Notes which may be distributed IN SPECIE to Unitholders in connection
with a redemption will not be listed on any stock exchange and no market is
expected to develop in such Long Term Notes or Redemption Notes.

MEETINGS OF UNITHOLDERS

The Trust Indenture provides that meetings of Unitholders must be called and
held for, among other matters, the election or removal of the Trustee, the
appointment or removal of our auditors, the approval of amendments to the Trust
Indenture (except as described under "Additional Information Respecting
Advantage Energy Income Fund - Amendments to the Trust Indenture"), the sale of
our assets in their entirety or substantially in their entirety (other than as
part of an internal


                                       32


reorganization), the termination of the Trust and the direction of the Trustee
as to the selection of the directors of AOG. Meetings of Unitholders will be
called and held annually for, among other things, the election of the Trustee,
the appointment of our auditors, and the direction of the Trustee as to the
selection of the directors of AOG. A resolution appointing or removing a
Trustee, our auditors, or the direction of the Trustee as to the selection of
the directors of AOG must be passed by a simple majority of the votes cast by
Unitholders. The balance of the foregoing matters must be passed by at least
66?% of the votes cast at a meeting of Unitholders called for such purpose.

A meeting of Unitholders may be convened at any time and for any purpose by the
Trustee and must be convened if requisitioned by the holders of not less than
20% of the Trust Units then outstanding by a written requisition. A requisition
must, among other things, state in reasonable detail the business proposed to be
transacted at the meeting.
Unitholders may attend and vote at all meetings of Unitholders either in person
or by proxy and a proxyholder need not be a Trust Unitholder. Two persons
present in person or represented by proxy and representing, in the aggregate, at
least 10% of the votes attaching to all outstanding Trust Units shall constitute
a quorum for the transaction of business at all such meetings.

The Trust Indenture contains provisions as to the notice required and other
procedures with respect to the calling and holding of meetings of Unitholders.
The next annual and special meeting of Unitholders is scheduled for April 27,
2005.

INFORMATION AND REPORTS

We will furnish to Unitholders such financial statements (including quarterly
and annual financial statements) and other reports as are, from time to time,
required by applicable law, including prescribed forms needed for the completion
of Unitholders' tax returns under the Tax Act and equivalent provincial
legislation.

Prior to each meeting of Unitholders, the Trustee will provide the Unitholders
(along with notice of such meeting) a proxy form and an information circular
containing information similar to that required to be provided to shareholders
of a Canadian public corporation.

The board of directors of AOG will ensure that AOG provides us with proper
disclosure as to its business and financial operations and sufficient
information and materials on a timely basis to allow us to meet our public
reporting requirements. With respect to material changes, the board of directors
of AOG will ensure that AOG provides timely disclosure to us as if AOG were a
public corporation.

TAKEOVER BIDS

The Trust Indenture contains provisions to the effect that if a takeover bid is
made for the Trust Units and not less than 90% of the Trust Units (other than
Trust Units held at the date of the takeover bid by or on behalf of the offeror
or associates or affiliates of the offeror) are taken up and paid for by the
offeror, the offeror will be entitled to acquire the Trust Units held by
Unitholders who did not accept the takeover bid on the terms offered by the
offeror.

THE TRUSTEE

The Trust Indenture provides that the Trustee shall exercise its powers and
carry out its functions thereunder as Trustee honestly, in good faith and in the
best interests of the Trust and the Unitholders and, in connection therewith,
shall exercise that degree of care, diligence and skill that a reasonably
prudent trustee would exercise in comparable circumstances.

The initial term of the Trustee's appointment is until the first annual meeting
of Unitholders. The Trustee is reappointed or changed every year as may be
determined by a majority of the votes cast at a meeting of our Unitholders. The
Trustee may resign upon 60 days' notice to us. The Trustee may also be removed
by special resolution of our Unitholders. Such resignation or removal becomes
effective upon the acceptance or appointment of a successor trustee.

DECISION-MAKING

Although the Manager will provide certain advisory and management services to us
pursuant to the Management Agreement, the board of directors of AOG will
supervise the management of our business and affairs, including our business and
affairs delegated to AOG. In particular, significant operational decisions and
all decisions relating to: (i) the acquisition and disposition of properties,
assets or securities (individually or in the aggregate with respect to any
single type of security) for a purchase price or proceeds in excess of
$2,000,000; (ii) the approval of annual operating and capital expenditure
budgets; and (iii) establishment of credit facilities, will be made by the board
of directors of AOG. In addition, the Trustee has delegated certain matters to
the board of directors of AOG, including making all decisions relating to: (i)
issuance of additional Trust Units; and (ii) the determination of the amount of
distributable income. Any amendment to any material contract to which we are a
party will require the approval of the board of directors of AOG on our behalf.
The board of directors of AOG generally intends to hold regularly scheduled
meetings to review the business and affairs of the Trust and AOG and to make any
necessary decisions relating thereto.

LIABILITY OF THE TRUSTEE

The Trustee, its directors, officers, employees, shareholders and agents shall
not be liable to any Trust Unitholder or any other person, in tort, contract or
otherwise, in connection with any matter pertaining to the Trust or the Trust
Fund, arising from the exercise by the Trustee of any powers, authorities or
discretion conferred under the Trust Indenture, including, without limitation,
any action taken or not taken in good faith in reliance upon any documents that
are, PRIMA FACIE, properly executed, any depreciation of, or loss to, the Trust
Fund incurred by reason of the sale of any asset, any inaccuracy in any
evaluation provided by the Manager or any other appropriately qualified person,
any reliance upon any such evaluation, any action or failure to act of the
Manager, AOG, or any other person to whom the Trustee has, with the consent of
AOG, delegated any of its duties hereunder, or any other action or failure to
act (including failure to compel in any way any former trustee to redress any
breach of trust or any failure by the Manager or AOG to perform its duties under
or delegated to it under the Trust Indenture or any material contract), unless
such liabilities arise out of the gross negligence, wilful default or fraud of
the Trustee or any of its directors, officers, employees, shareholders or
agents. If the Trustee has retained an appropriate expert, adviser or legal
counsel with respect to any matter connected with its duties under the Trust
Indenture or any material contract, the Trustee may act or refuse to act based
upon the advice of such expert, adviser or legal counsel, and the Trustee shall
not be liable for and shall be fully protected from any loss or liability
occasioned by any action or refusal to act based upon the advice of any such
expert, adviser or legal counsel. In the exercise of the powers, authorities or
discretion conferred upon the Trustee under the Trust Indenture, the Trustee is
and shall be conclusively deemed to be acting as Trustee of the assets of the
Trust and shall not be subject to any personal liability for any debts,
liabilities, obligations, claims, demands, judgments, costs, charges or expenses
against or with


                                       34


respect to the Trust or the Trust Fund. In addition, the Trust
Indenture contains other customary provisions limiting the liability of the
Trustee.

66?% of the votes cast at a meeting of our Unitholders called for such purpose.

amendments to the Trust Indenture, including amendments:

         prejudicial to the Unitholders;

the Trust Indenture, termination of the Trust or the sale or transfer of our
assets in their entirety or substantially in their entirety, except as part of
an internal reorganization of the our assets as approved by the board of
directors of AOG, requires approval by at least 66?% of the votes cast at a
meeting of the Unitholders.

EXERCISE OF VOTING RIGHTS ATTACHED TO COMMON SHARES

The Trust Indenture provides that the Trustee may vote securities of AOG held by
it at any meeting of shareholders of AOG as well as any Permitted Investments
held, from time to time, as part of the Trust Fund which carry voting rights.
However, the Trustee may not, under any circumstances whatsoever, vote any AOG
securities or any other Permitted Investments which carry voting rights to
authorize the sale, lease or exchange of all or substantially all of the
property of AOG or any other entity owned directly or indirectly by us which
represents more than 51% of the Trust Fund, except as part of a reorganization
of AOG and any one or more of our directly or indirectly owned subsidiaries

         Columbia Securities Commission on November 8, 2002 and October 23,
         2002, respectively. Cease trade orders were issued because Shenandoah
         failed to file certain required financial statements. As of the date
         hereof, the cease trade orders remain outstanding. Shenandoah's common
         shares were suspended from trading on the TSX Venture Exchange on April

         July 7, 2000 and July 17, 2000, respectively. The cease trade orders
         were issued because Probe failed to file certain required financial
         statements. As at the date hereof, the cease trade orders remain
         outstanding. Probe's common shares were suspended from trading on the
         TSX on March 17, 2000, and were subsequently delisted from the TSX at
         the close of business on March 16, 2001. Mr. Tourigny resigned his
         directorship with Probe effective April 14, 2000.

As at February 15, 2005, the directors and executive officers of AOG, as a
group, beneficially owned, directly or indirectly, or exercised control or
direction over, 2,039,452 Trust Units, or approximately 3.6% of the issued and
outstanding Trust Units.


CEASE TRADE ORDERS, BANKRUPTCIES, PENALTIES OR SANCTIONS

Except as disclosed above, no director or officer of Advantage, or a shareholder
holding a sufficient number of securities of Advantage to affect materially the
control of Advantage is, or within the last ten years has been, a director or
officer of any reporting issuer that, while such person was acting in that
capacity, was the subject of a cease trade or similar order or an order that
denied us access to any statutory exemption for a period of more than 30
consecutive days or, within a year of such person ceasing to act in that
capacity or within the 10 years prior to the date hereof, become bankrupt, made
a proposal under any legislation relating to bankruptcy or insolvency or was
subject to or instituted any proceedings, arrangement or compromise with
creditors or had a receiver, receiver manager or trustee appointed to hold the
assets of that person.

No director or officer of Advantage, or a shareholder holding a sufficient
number of securities of Advantage to affect materially the control of Advantage,
has been subject to any penalties or sanctions under securities legislation or
by a


                                       38


securities regulatory authority or has entered into a settlement agreement
with a securities regulatory authority or any other penalties or sanctions
imposed by a court or regulatory body that would likely be considered important
to a reasonable investor in making an investment decision.

DISTRIBUTION POLICY

It is anticipated that income we receive will be from: (i) the interest received
on the principal amount of the Notes; (ii) royalty income from the Royalty; and
(iii) the dividends received from the shares of AOG. The Trustee makes monthly
cash distributions to Unitholders of the interest income earned from the Notes,
royalty income from the Royalty and dividends, if any, received on Common
Shares, after expenses, if any, and any cash redemptions of Trust Units. See
"Risk Factors - Oil and Natural Gas Prices/Delay in Cash
Distributions/Dependence on AOG".

SHARE CAPITAL

AOG is authorized to issue an unlimited number of Common Shares, Non-Voting
Shares, Preferred Shares and Exchangeable Shares. We are the sole holder of the
issued and outstanding Common Shares. There are no Non-Voting Shares or
Preferred Shares issued and outstanding. We are also the sole holder of the
outstanding Notes.

The following is a description of the rights attaching to the Common Shares,
Non-Voting Shares, Preferred Shares, Exchangeable Shares and Notes.

COMMON SHARES

Each Common Share entitles its holder to receive notice of and to attend all
meetings of the shareholders of AOG and to one vote at such meetings. The
holders of Common Shares are, at the discretion of the Board of Directors and
subject to applicable legal restrictions, entitled to receive any dividends
declared by the Board of Directors on the Common Shares. The holders of Common
Shares are entitled to share equally in any distribution of the assets of AOG
upon the liquidation, dissolution, bankruptcy or winding-up of AOG or other
distribution of its assets among its shareholders for the purpose of winding-up
its affairs. Such participation is subject to the rights, privileges,
restrictions and conditions attaching to any instruments having priority over
the Common Shares.

NON-VOTING SHARES

The Non-Voting Shares have identical rights to the Common Shares except that
holders of Non-Voting Shares are not generally entitled to receive notice of or
attend at meetings of shareholders of AOG or to vote their shares at such
meetings.

PREFERRED SHARES

The Preferred Shares may be issued, from time to time, in one or more series,
each series consisting of such number of Preferred Shares as determined by the
Board of Directors, who may also fix the designations, rights, privileges,
restrictions and conditions attached to the shares of each series of Preferred
Shares. No Preferred Shares are presently issued and outstanding. The Preferred
Shares of each series shall, with respect to payment of dividends and
distributions of assets in the event of liquidation, dissolution or winding-up
of AOG, whether voluntary or involuntary, or any other distribution of the
assets of AOG among its shareholders for the purpose of winding-up its affairs,
rank on a parity with the Preferred Shares of every other series and shall be
entitled to preference over the Common Shares and the shares of any other class
ranking junior to the Preferred Shares.

EXCHANGEABLE SHARES

As at December 31, 2004, AOG had 1,450,030 Exchangeable Shares outstanding. The
Exchangeable Shares were issued in connection with our acquisition of Defiant.
Each Exchangeable Share is exchangeable for Trust Units at any time (subject to
the provisions of the Voting and Exchange Trust Agreement), on the basis of the
applicable exchange ratio in effect at that time, in accordance with the share
provisions applicable to such shares and the terms and provisions of the Voting
and Exchange Trust Agreement. The exchange ratio was initially equal to one upon
issuance of the Exchangeable


                                       39


Shares and will increase on each date that a distribution is paid by us on the
Trust Units. The exchange ratio will decrease on each record date for the
payment of dividends on the Exchangeable Shares. The holders of Exchangeable
Shares are not entitled to any vote at meetings of shareholders of AOG but are,
through the Special Voting Unit of Advantage held by the Trustee as trustee
under the Voting and Exchange Trust Agreement, entitled to vote (on the basis of
the number of votes equal to the number of Trust Units into which the
Exchangeable Shares are then exchangeable) with the holders of Trust Units as a
class. In addition, holders are provided with all information sent by us to
Unitholders. Holders of Exchangeable Shares will be entitled to receive, as and
when declared by the board of directors of AOG in its sole discretion from time
to time, such cash dividends as may be declared thereon by the board of
directors. It is not anticipated that dividends will be declared or paid on the
Exchangeable Shares. The Exchangeable Shares will be redeemable by AOG, in
certain circumstances, and will be retractable by holders of Exchangeable
Shares, in certain circumstances. Exchangeable Shares not previously redeemed or
retracted will be redeemed by AOG or purchased by us on January 15, 2008.

NOTES

The following is a summary of the material attributes and characteristics of the
Notes. This summary does not purport to be complete and is qualified in its
entirety by reference to the provisions of the Note Indentures, pursuant to
which the Notes are issued.

PAYMENT UPON MATURITY

On maturity and subject to any applicable subordination restrictions, AOG will
repay the indebtedness represented by the Notes by paying to the Note Trustee,
in lawful money of Canada, an amount equal to the principal amount of the
outstanding Notes, together with accrued and unpaid interest thereon.

RANKING

Payment of the principal and interest (other than regularly scheduled interest
and principal at maturity, provided no default on Senior Indebtedness (as
hereinafter defined) has occurred and payment of such interest or principal is
not otherwise required to be suspended in accordance with the terms of
subordination agreements which may be entered into with the holders of Senior
Indebtedness (as herein defined)) on the Notes will be subordinated in right of
payment, as set forth in the Note Indentures, to the prior payment in full of
the principal of and accrued and unpaid interest on, and all other amounts owing
in respect of, all senior indebtedness ("SENIOR INDEBTEDNESS") which is defined
as: (a) all indebtedness, obligations and liabilities of AOG in respect of
borrowed money (including the deferred purchase price of property), other than:
(i) indebtedness evidenced by the Note Indentures; and (ii) indebtedness which,
by the terms of the instrument creating or evidencing the same, is expressed to
rank in right of payment equally with or subordinate to the indebtedness
evidenced by the Note Indentures; and (b) from and after the commencement of,
and during the continuance of, any creditor proceedings (including bankruptcy,
liquidation, winding-up, dissolution, restructuring or arrangement proceedings),
all indebtedness, obligations and liabilities of AOG, other than indebtedness,
obligations and liabilities of AOG represented by the Notes. The Note Indentures
provide that in the event of any creditor proceedings relative to AOG, the
holders of all Senior Indebtedness, which would include bank debt and suppliers
of AOG, will be entitled to receive payment in full before the holders of the
Notes are entitled to receive any payment. Any amount of property received
contrary to these provisions shall be held in trust for and paid over to the
holders of Senior Indebtedness.

In the event of any creditor proceedings, the indebtedness represented by the
Notes is not to be classified with any Senior Indebtedness for voting or
distribution, which means that holders of Senior Indebtedness may vote
separately from the holders of Notes in respect of any restructuring or
arrangement proposal regarding AOG.

DEFAULT

The Note Indentures provides that any of the following shall constitute an
"Event of Default": (i) default in payment of the principal of the Notes when
the same becomes due; (ii) the failure to pay the interest obligations of the
Notes for a period of 12 months; (iii) default on any indebtedness exceeding
$10,000,000; (iv) certain events of winding-up, liquidation, bankruptcy,
insolvency or receivership; (v) the taking of possession by an encumbrancer of
all or substantially all of the property of AOG; or (vi) default in the
observance or performance of any other covenant or


                                       40


condition of the Note Indenture and the continuance of such default for a period
of 30 days after notice in writing has been given by the Note Trustee to AOG
specifying such default and requiring AOG to rectify the same.

SUBORDINATION AGREEMENTS

Pursuant to the terms of the Note Indentures, the Note Trustee may enter into
subordination agreements with the holders of certain Senior Indebtedness under
which the Note Trustee, on behalf of the holders of Notes, may agree directly
with a holder of Senior Indebtedness in implementation of and/or in addition to
the subordination terms described under "Ranking" directly above. The Note
Trustee may give a holder of Senior Indebtedness a power of attorney to be
exercised in any creditor proceedings to enforce the terms thereof. The Note
Trustee may also agree to ensure that any transferee of Notes (or other
securities of AOG) agrees to be bound by the provisions of the subordination
agreements.

LONG TERM NOTES

The aggregate principal amount of Long Term Notes as at December 31, 2004 was
$475,312,732. The Long Term Notes mature on December 31, 2031. The Long Term
Notes consist of a series of notes, which as at the date hereof, includes Long
Term Notes bearing interest at a rate of 14% and 12.5% per annum, payable
monthly on the 15th day of the month (or, if such day is not a Business Day, the
first Business Day thereafter) for interest earned during the preceding month.
The principal and interest on the Long Term Notes are payable in lawful money of
Canada. The Long Term Notes are issuable only as fully-registered notes in
minimum denominations of $100.00 and integral multiples of $1.00.

REDEMPTION OF LONG TERM NOTES

The Long Term Notes will not be redeemable at the option of AOG or by the
holders thereof prior to maturity except in the limited circumstances prescribed
by Long Term Note Indenture, where the Board of Directors believe the
indebtedness represented by the Long Term Notes could not be refinanced on
maturity, or where AOG is prevented by applicable law from paying dividends or
making other distributions in respect of Common Shares.

MEDIUM TERM NOTES

The original aggregate principal amount of Medium Term Notes was $259,200,000
("ORIGINAL PRINCIPAL AMOUNT") and the aggregate principal amount of the Medium
Term Notes as at December 31, 2004 was $207,624,757. The Medium Term Notes
consist of a series of notes, which as of December 31, 2004, includes Medium
Term Notes bearing interest at rates between 7.75% and 10.375% per annum,
payable twice annually, and maturing between December 31, 2012 and December 21,
2015. The principal and interest on the Medium Term Notes are payable in lawful
money of Canada. The Medium Term Notes are issuable only as fully-registered
notes in minimum denominations of $100.00 and integral multiples of $1.00.

PRINCIPAL REPAYMENTS AND REDEMPTION OF MEDIUM TERM NOTES

From time to time and in any event not less frequently than each anniversary of
December 31, 2004, AOG shall make principal repayments on the Notes in an
aggregate amount equal to not less than 5% of the Original Principal Amount
(and, if applicable, the aggregate principal amount of any additional Notes
issued under the Medium Term Note Indenture in excess of the Original Principal
Amount (the "SUPPLEMENTAL PRINCIPAL AMOUNT")), provided, however that during the
period commencing on September 30, 2004 and ending on December 31 of the year
ended five years before the Maturity Date, AOG shall make, in aggregate,
principal payments on the Notes in an amount equal to not less than 50% of the
Original Principal Amount. In the event that, at any time during the term of
this Indenture, a Supplemental Principal Amount is outstanding, during the
period commencing with the issue date of the Notes relating to the Supplemental
Principal Amount and ending five years from such issue date, AOG shall make
principal payments on the Notes relating to the Supplemental Principal Amount in
an aggregate amount equal to not less than 50% of the Supplemental Principal
Amount. In the event that AOG makes principal repayments on the Notes pursuant
to this section of the Medium Note Indenture and there is more than one holder
thereof, such principal prepayments shall be made as near as may be pro rata as
between the holders and without discrimination or preference, based upon the
aggregate principal amount of Notes held by them (rounded, if necessary, to the
nearest One Dollar ($1.00)).


                                       41


THE ROYALTY AGREEMENT

Pursuant to the Royalty Agreement, AOG has granted to us the Royalty on AOG's
interest in Petroleum Substances within, upon or under all of AOG's developed
and undeveloped Canadian Oil and Natural Gas Properties

The Royalty will consist of the right to receive a monthly payment from AOG
equal to the "Royalty Production Income", which in respect of any period for
which Royalty is calculated, means 95% of the production revenues from the
Properties less an equivalent portion of the amount of all deductions permitted
under the Royalty Agreement. The Royalty does not constitute an interest in land
and we are not entitled to take our share of production in kind or to separately
sell or market our share of Petroleum Substances.

Pursuant to the Royalty Agreement approximately 95% of the economic benefit
derived from the assets of AOG accrues to the benefit of the Fund and ultimately
to us and our Unitholders. The term of the Royalty Agreement will be for so long
as there are Properties to which the Royalty Agreement applies.

If AOG wishes to dispose of any properties that will result in proceeds in
excess of $2 million, AOG's board of directors is required to approve such
disposition.

SHAREHOLDER AGREEMENT

Pursuant to the Shareholder Agreement, prior to us voting our shares in AOG,
each Unitholder shall be entitled to vote in respect of the matter on the basis
of one vote per Trust Unit held and we shall be required to vote our shares in
AOG in accordance with the result of the vote of Unitholders. Holders of Trust
Units shall be entitled to direct the Trust as to how to vote in respect of all
matters placed before the shareholder of AOG, including, subject to the right of
the Manager to designate two directors, the election of the directors of AOG,
approving its financial statements, and appointing auditors of AOG, who shall be
the same as our auditors. In addition, Unitholders will be entitled to direct us
as to how to vote our shares in AOG on any proposed amendment to the Shareholder
Agreement, where such amendment affects the rights of Unitholders to elect a
majority of the Board of Directors. We will not be entitled, without the
direction of Unitholders, to exercise our rights as the sole shareholder of AOG
except as set forth above.

It is a term of the Shareholder Agreement that the Board of Directors shall
consist of a minimum of five and a maximum of nine directors, with the present
number of directors set at seven. The Shareholder Agreement provides that
Unitholders are entitled to select a majority of the Board of Directors. Under
the terms of the Shareholder Agreement, the Manager has the right to designate
two directors to be elected to the Board of Directors.

                  discharge by them of their responsibilities as officers or

2.       to us:

                  securities legislation;

         (b)      provide investor relations services;

         (g)      recommend investments in Permitted Investments.

The Manager is paid fees for providing all of the services in items 1 and 2
above. See "Additional Information Respecting Advantage Investment Management
Ltd. - Compensation and Term". Notwithstanding the delegations provided in items
1 and 2 above, the board of directors of AOG will supervise the management of
the business and affairs of AOG, including our business and affairs delegated to
AOG, and, in particular:

1.       significant operational decisions in respect of AOG as identified by
         the Manager, acting reasonably; and

2.       decisions relating to:

         (a)      any offerings, including the issuance of additional Trust
                  Units or securities convertible into or exchangeable for Trust
                  Units;

         (b)      the acquisition and disposition of properties, assets,
                  securities (individually or in the aggregate with respect to
                  any single type of security) for a purchase price or proceeds
                  in excess of $2,000,000;

         (c)      the approval of operating and capital expenditure budgets;

         (d)      the establishment of credit facilities;

         (e)      all matters to do with the continued listing of the Trust
                  Units on any exchange and to maintain our status as a
                  reporting issuer, including press releases and material change
                  reports as required by continuous disclosure requirements of
                  applicable securities legislation;

         (f)      the determination of the amount of distributable income; and

         (g)      the approval of any amendment to the Management Agreement, the
                  Royalty Agreement, the Note Indentures or the Shareholder
                  Agreement on our behalf, and those matters as set forth in the
                  Trust Indenture, that may be amended without the approval of
                  Unitholders;

shall be subject to the approval of the board of directors of AOG.

The Manager and the Trust are responsible for ensuring compliance with the
continuous disclosure obligations under all applicable securities legislation.
The Manager has been indemnified by AOG and the Trust in respect of damages
suffered relating to the performance of services under the Management Agreement
provided that the Manager is in compliance with the standard of care described
below, and any of its directors, officers or employees have been indemnified by
AOG and the Trust provided that such person shall not be found to be liable for
or guilty of wilful misfeasance, bad faith, gross negligence or reckless
disregard of his or her duty to AOG or the Trust.

In exercising its powers and discharging its duties under the Management
Agreement, the Manager is required to exercise that degree of care, diligence
and skill that a reasonably-prudent operator and manager in respect of oil and
gas properties in western Canada and a manager of a publicly-traded reporting
issuer, having responsibility for the subject management, advisory and
administrative services, would exercise in comparable circumstances.

ACQUISITION AND DISPOSITION STRATEGY

The strategy employed by the Manager is to maintain the level of production of
oil and natural gas from AOG's existing properties and to supplement production
by reserve acquisitions. To maintain production, capital expenditures are


                                       45


focused on development activity as opposed to exploration. Exploration
properties are generally sold, farmed out or developed using third party
resources. Reserve replacement and additions are achieved through development
activity and acquisitions.

In addition, as part of the services to be provided by the Manager to AOG and
the Trust, the Manager may recommend that AOG enter into agreements to dispose
of Oil and Natural Gas Properties and make farmouts and other dispositions of
such properties. Approval by the board of directors of AOG of any acquisitions
or dispositions is required where the properties being acquired or disposed of
have a purchase price or proceeds in excess of $2,000,000.

COMPENSATION AND TERM

In its role under the Management Agreement as manager and administrator of us
and AOG, the Manager receives the following:

1.       a fee in an amount equal to 1.5% of Operating Cash Flow, such amount to
         be calculated as at the end of each calendar quarter or portion
         thereof, if applicable, and paid on the 45th day following any such
         calendar quarter, or, if such day is not a Business Day, on the next
         Business Day; and

2.       a fee in an amount equal to 10% of the Total Return Amount (which
         means, in respect of any Return Period, an amount equal to the Total
         Return Percentage minus 8% if the Return Period is a full calendar
         year, and adjusted appropriately should the Return Period be less than
         a full calendar year, multiplied by the Market Capitalization for that
         Return Period), such amount to be calculated as at the end of each
         Return Period and paid on the 15th day following the end of each such
         Return Period, or, if such day is not a Business Day, on the next
         Business Day.

In addition, the Manager has the option (subject to any necessary regulatory
approval) of receiving all or part of the fee provided in paragraph 2 above in
Trust Units at the Unit Market Price calculated as at the end of the relevant
period.

The Manager representatives who act as employees or officers of AOG are entitled
to participate in any benefit plans in place for AOG employees (including under
any incentive plan) and are entitled to industry-competitive salaries (as
approved by the board of directors of AOG) for acting in such capacity.

The Manager does not receive any acquisition or disposition fees.

It is the intention of the Manager that the management fees referred to in
paragraphs 1 and 2 above (collectively, the "MANAGEMENT FEES") will fund all
employee bonuses and incentive plans. Effective October 4, 2004, such fees are
allocated by the Manager, subject to the discretion of the Manager, on the
following basis:

                Manager
                          Operating Fee                    66 2/3%
                         Termination Fee                   66 2/3%
                         Performance Fee                   60%
                Employees of AOG
                         Operating Fee                     33 1/3%
                         Termination Fee                   33 1/3%
                         Performance Fee                   40%

The allocation of the Management Fees and the Termination Fees (as defined
below) amongst the employees of AOG will be based upon the recommendations of
the Manager as approved by the board of directors of AOG.

The initial term of the Management Agreement was for 3 years, and on each
anniversary date of the Management Agreement it automatically renews on an
"evergreen" basis for additional one-year periods, provided that the board of
directors of AOG has not provided notice to the Manager prior to any such
renewal that such renewal shall not occur. In all instances of termination
(except where the Management Agreement terminates at the end of the term), a
termination fee ("TERMINATION FEES") equal to the Management Fees paid for the
immediately-prior 2 1/2 years shall be payable.


                                       46


In addition, the Manager is entitled to reimbursement, by us and AOG, of General
and Administrative Costs and expenses related to the Manager's performance under
the Management Agreement, other than costs related solely to the Manager and
costs related to employee bonuses and incentive plans.

CONFLICTS OF INTEREST

The executive officers of the Manager have extensive experience in the oil and
gas business and in the management of private and public entities. As a result,
certain of the directors, officers and employees of the Manager, and certain of
the consultants retained by the Manager, from time to time, may also be
directors, officers and employees of affiliates of the Manager or may be
consultants retained by affiliates of the Manager. The Management Agreement
contains provisions which require the Manager to make disclosure to the Trustee
and the board of directors of AOG of the fact and substance of any particular
conflict of interest, if one should occur, and to use all reasonable efforts to
resolve such conflict of interest in a manner which will treat us or AOG, as the
case may be, and the other interested party in an even-handed manner, taking
into account all of the circumstances of the Trust or AOG, as the case may be,
and such interested party, and to act honestly and in good faith in resolving
such matters.

Pursuant to the Management Agreement, the Manager has agreed to make Kelly
Drader available for the performance of the services to be provided to us and
AOG and in acting as AOG's President and Chief Executive Officer.

The Management Agreement also provides that the Manager and the ManagementCo
Group agree that they will not do any of the following activities except with
prior disclosure to the board of directors of AOG of the nature and extent of
their interest in such activities and a description of such activities and
unless, in each case, the consent of the board of directors of AOG is first
obtained:

1.       they will not manage another oil and gas income fund or royalty trust;

2.       they will not, without prior approval of us and AOG, acting reasonably,
         as determined by the board of directors of AOG, make investments in or
         acquire oil and gas assets or income funds, royalty trusts or companies
         owning oil and gas assets, except for the purchase of securities of
         public oil and gas companies, income funds or royalty trusts on a
         recognized stock exchange for investment purposes. Such shareholding in
         each such investment shall not exceed 10% of the issued and outstanding
         securities of any such issuer; and

3.       they will not, without prior approval of us and AOG, acting reasonably,
         as determined by the board of directors of AOG, conduct any other
         business activities relating to Canadian resource properties or
         rendering services or acting as advisor or manager to any other person
         or entity that may have investment or business interests similar to
         those of us or AOG.

As at the date hereof, neither the Trust, AOG nor the Manager is aware of any
existing or potential material conflicts of interest between the Trust and/or
AOG and a director or officer of the Manager.

PRE-APPROVAL OF POLICIES AND PROCEDURES

We have adopted polices and procedures with respect to the pre-approval of audit
and permitted non-audit services to be provided by KPMG LLP as set forth in item
15 of the Audit Committee charter, which is reproduced below under the heading
"Audit Committee Charter". The Audit Committee has approved the provision of a
specified list of audit and permitted non-audit services that the audit
committee believes to be typical, reoccurring or otherwise likely to be provided
by KPMG LLP during the current fiscal year. The list of services is sufficiently
detailed as to the particular services to be provided to ensure that the audit
committee knows precisely what services it is being asked to pre-approve and it
is not necessary for any member of management to make a judgment as to whether a
proposed service fits within pre-approved services.

                             AUDIT COMMITTEE CHARTER

The following is a summary of our Audit Committee charter which was originally
approved by the board of directors of AOG on April 30, 2002 and amended in April
2003 and April 2004:


                                       53


PURPOSE

The primary function of the Audit Committee is to assist the Board of Directors
(the "BOARD OF DIRECTORS" or "BOARD") of Advantage Oil & Gas Ltd. in fulfilling
its responsibilities by reviewing: the financial reports and other financial
information provided by Advantage Energy Income Fund to any governmental body or
the public; the Trust's systems of internal controls regarding finance,
accounting, legal compliance and ethics that management and the Board have
established; and the Trust's auditing, accounting and financial reporting
processes generally. Consistent with this function, the Audit Committee should
endeavor to encourage continuous improvement of, and should endeavor to foster
adherence to, the Trust's policies, procedures and practices at all levels. The
Audit Committee's primary objectives are to:

1.       To assist directors meet their responsibilities (especially for
         accountability) in respect of the preparation and disclosure of the
         financial statements of the Trust and related matters;

2.       To provide better communication between directors and external
         auditors;

3.       To enhance the external auditor's independence;

4.       To increase the credibility and objectivity of financial reports; and

5.       To strengthen the role of the outside directors by facilitating
         discussions between directors on the Audit Committee, management and
         external auditors.

COMPOSITION

The Audit Committee shall be comprised of three or more directors as determined
by the Board of Directors, none of whom are members of management of AOG, the
Trust or Advantage Investment Management Ltd. and all of whom are "unrelated
directors" (as such term is used in the Report of the Toronto Stock Exchange on
Corporate Governance in Canada) and "independent" (as such term is used in
Multilateral Instrument 52-110 -- Audit Committees ("MI 52-110"). All of the
members of the Audit Committee shall be "financially literate". The Board of
Directors has adopted the definition for "FINANCIAL LITERACY" used in MI 52-110
which means "the ability to read and understand a set of financial statements
that present a breadth and level of complexity of accounting issues that are
generally comparable to the breadth and complexity of the issues that can
reasonably be expected to be raised by the issuer's financial statements". Audit
Committee members may enhance their familiarity with finance and accounting by
participating in educational programs conducted by the Trust or an outside
consultant.

The members of the Audit Committee shall be elected by the Board of Directors at
the annual organizational meeting of the Board of Directors and remain as
members of the Audit Committee until their successors shall be duly elected and
qualified. Unless a Chair is elected by the full Board of Directors, the members
of the Audit Committee may designate a Chair by majority vote of the full Audit
Committee membership.

MEETINGS

The Audit Committee shall meet at least four times annually, or more frequently
as circumstances dictate. As part of its job to foster open communication, the
Audit Committee should meet at least annually with management and the
independent auditors in separate executive sessions to discuss any matters that
the Audit Committee or each of these groups believe should be discussed
privately. In addition, the Audit Committee or at least its Chair should meet
with the independent auditors and management quarterly to review the Trust's
financials consistent with item 4 below.

A quorum for meetings of the Audit Committee shall be a majority of its members,
and the rules for calling, holding, conducting and adjourning meetings of the
Audit Committee shall be the same as those governing the Board.

RESPONSIBILITIES AND DUTIES

To fulfill its responsibilities and duties, the Audit Committee shall endeavor
to:

         auditors and determine which non-audit services the external auditor is
         prohibited from providing. The Audit Committee may delegate to one or
         more members of the Audit Committee authority to pre-approve non-audit
         services in satisfaction of this requirement and if such delegation
         occurs, the pre-approval of non-audit services by the Audit Committee
         member to whom authority has been delegated must be presented to the
         Audit Committee at its first scheduled meeting following such
         pre-approval. The Audit Committee shall be entitled to adopt specific

                  which the services are provided;

16.      the services are promptly brought to the attention of the Audit

                                  RISK FACTORS

The following is a summary of certain risk factors relating to the business of
AOG and the Trust. The following information is a summary only of certain risk
factors and is qualified in its entirety by reference to, and must be read in
conjunction with, the detailed information appearing elsewhere in this renewal
annual information form.

DEPENDENCE ON AOG

We are an open-ended, limited purpose trust which will be entirely dependent
upon the operations and assets of AOG through our ownership of the Common
Shares, the Notes and the Royalty. Accordingly, the cash distributions to our
Unitholders will be dependent upon the ability of AOG to meet its interest and
principal repayment obligations under the Notes to declare and pay dividends on
the Common Shares, and to pay the Royalty. AOG's income will be received from
the production of oil and natural gas from AOG's existing Canadian resource
properties and will be susceptible to the risks and uncertainties associated
with the oil and natural gas industry generally. AOG is generally not involved
in the exploration for oil and natural gas. As a result, if the oil and natural
gas reserves associated with AOG's Canadian resource properties are not
supplemented through additional development or the acquisition of additional Oil
and Natural Gas Properties, the ability of AOG to meet its obligations to us may
be adversely affected.


                                       57


EXPLOITATION AND DEVELOPMENT

Exploitation and development risks are due to the uncertain results of searching
for and producing oil and natural gas using imperfect scientific methods. These
risks are mitigated by using highly skilled staff, focusing exploitation efforts
in areas in which we have existing knowledge and expertise or access to such
expertise, using up-to-date technology to enhance methods, and controlling costs
to maximize returns. Advanced oil and natural gas related technologies such as
three-dimensional seismography, reservoir simulation studies and horizontal
drilling have been and will be used by us to improve our ability to find,
develop and produce oil and natural gas.

OPERATIONS

AOG's operations are subject to all of the risks normally incident to the
operation and development of Oil and Natural Gas Properties and the drilling of
oil and natural gas wells, including encountering unexpected formations or
pressures, blow-outs, craterings and fires, all of which could result in
personal injuries, loss of life and damage to the property of AOG and others.
AOG has both safety and environmental policies in place to protect its operators
and employees, as well as to meet the regulatory requirements in those areas
where it operates. In addition, AOG has liability insurance policies in place,
in such amounts as it considers adequate, however, it will not be fully insured
against all of these risks, nor are all such risks insurable. Costs incurred to
repair any of such damage or pay any of such liabilities will reduce Royalty
Income.

Continuing production from a property, and, to some extent the marketing of
production therefrom, are largely dependent upon the ability of the operator of
the property. To the extent the operator fails to perform these functions
properly, revenue may be reduced. Payments from production generally flow
through the operator and there is a risk of delay and additional expense in
receiving such revenues if the operator becomes insolvent. Although satisfactory
title reviews are generally conducted in accordance with industry standards,
such reviews do not guarantee or certify that a defect in the chain of title may
not arise to defeat the claim of AOG to certain Properties. A reduction of the
income from the Royalty could result in such circumstances.

EXPANSION OF OPERATIONS

The operations and expertise of our management are currently focused on
conventional oil and gas production and development in the Western Canadian
Sedimentary Basin. In the future, we may acquire oil and gas properties outside
this geographic area. In addition, the Trust Indenture does not limit our
activities to oil and gas production and development, and we could acquire other
energy related assets, such as oil and natural gas processing plants or
pipelines, or an interest in an oil sands project. Expansion of our activities
into new areas may present new additional risks or alternatively, may
significantly increase the exposure to one or more of the present risk factors
which may result in our future operational and financial conditions being
adversely affected.

OIL AND NATURAL GAS PRICES

The monthly cash distributions we pay to Unitholders are highly dependent upon
the prices received for AOG's oil and natural gas production. Oil and natural
gas prices can fluctuate widely on a month-to-month basis in response to a
variety of factors that are beyond the control of us and AOG. These factors
include, among others:

o        political conditions throughout the world;
o        worldwide economic conditions;
o        weather conditions;
o        the supply and price of foreign oil and natural gas;
o        the level of consumer demand;
o        the price and availability of alternative fuels;
o        the proximity to, and capacity of, transportation facilities;
o        the effect of worldwide energy conservation measures; and
o        government regulations.


                                       58


Declines in oil or natural gas prices will have an adverse effect upon our
operations, financial condition, reserves and ultimately on our ability to pay
distributions to Unitholders.

We may manage the risk associated with changes in commodity prices by entering
into oil or natural gas price hedges. If we hedge our commodity price exposure,
we will forego the benefits it would otherwise experience if commodity prices
were to increase. In addition, commodity hedging activities could expose us to
losses. To the extent that we engage in risk management activities related to
commodity prices, we will be subject to credit risks associated with
counterparties with which we contract.

Oil prices were relatively high throughout 2004 averaging US$41.43 WTI as
compared to an average of US$31.06 WTI in 2003, an increase of 33%.

Monthly AECO prices averaged $6.79/Mcf in 2004 as compared to $6.67/Mcf in 2003,
an increase of 2%. The monthly AECO price in 2004 ranged from a high of
$8.00/Mcf in November to a low of $5.69/Mcf in October. The price of oil and
natural gas will fluctuate and price and demand are factors beyond our control.
Such fluctuations will have a positive or negative effect upon the revenue to be
received by it. Such fluctuations will also have an effect upon the acquisition
costs of any future Oil and Natural Gas Properties that we may acquire. As well,
cash distributions from us will be highly sensitive to the prevailing price of
crude oil and natural gas.

MARKETING

The marketability and price of oil and natural gas that may be acquired or
discovered by us will be affected by numerous factors beyond our control. These
factors include demand for oil and natural gas, market fluctuations, the
proximity and capacity of oil and natural gas pipelines and processing equipment
and government regulations, including regulations relating to environmental
protection, royalties, allowable production, pricing, importing and exporting of
oil and natural gas.

CAPITAL INVESTMENT

To the extent that AOG uses cash flow to finance acquisitions, development costs
and other significant expenditures, the net cash flow of the Trust will be
reduced. Hence, the timing and amount of capital expenditures may affect the
amount of net cash flow available to us and, as a consequence, the amount of
cash available to distribute to Unitholders. Therefore, distributions may be
reduced, or even eliminated, at times when significant capital or other
expenditures are made.

The board of directors of AOG has the discretion to determine the extent to
which cash flow will be allocated to the payment of debt service charges as well
as the repayment of outstanding debt, including under the credit facility. As a
consequence, the amount of funds retained by AOG to pay debt services charges or
reduce debt will reduce the amount of cash distributed to Unitholders during
those periods in which funds are so retained.

ASSESSMENTS OF VALUE OF ACQUISITIONS

Acquisitions of resource issuers and resource assets will be based in large part
upon engineering and economic assessments made by independent engineers. These
assessments will include a series of assumptions regarding such factors as
recoverability and marketability of oil and gas, future prices of oil and gas
and operating costs, future capital expenditures and royalties and other
government levies which will be imposed over the producing life of the reserves.
Many of these factors are subject to change and are beyond our control. In
particular, the prices of and markets for resource products may change from
those anticipated at the time of making such assessment. In addition, all such
assessments involve a measure of geologic and engineering uncertainty which
could result in lower production and reserves than anticipated. Initial
assessments of acquisitions may be based upon reports by a firm of independent
engineers that are not the same as the firm that we use for our year end reserve
evaluations. Because each of these firms may have different evaluation methods
and approaches, these initial assessments may differ significantly from the
assessments of the firm used by us. Any such instance may offset the return on
and value of the Trust Units.


                                       59


CHANGES IN ACCOUNTING STANDARDS APPLICABLE TO CONVERTIBLE DEBENTURES

On November 3, 2003 the Accounting Standards Board of the Canadian Institute of
Chartered Accountants approved a change to the accounting standards applicable
to convertible debentures such as those issued by us. The new standard requires
that the amounts outstanding under the Debentures be classified as liabilities
and that the interest costs on the Debentures be included as interest expense in
the determination of net income. The new standards are effective for fiscal
periods beginning on or after November 1, 2004.

DEBT SERVICE

AOG has credit facilities in the amount of $310,000,000. Variations in interest
rates and scheduled principal repayments could result in significant changes in
the amount required to be applied to debt service before payment of any amounts
to us. Although it is believed that the bank line of credit is sufficient, there
can be no assurance that the amount will be adequate for the financial
obligations of AOG or that additional funds can be obtained.

The lenders have been provided with security over substantially all of the
assets of AOG. If AOG becomes unable to pay its debt service charges or
otherwise commits an event of default such as bankruptcy, the lenders may
foreclose on or sell the Properties free from or together with the Royalty. The
payment of interest and principal on debt may also result in us or our
subsidiaries having taxable income and cash taxes payable as taxable income
would no longer be reduced by royalty payments at the time debt repayment
occurs.

PRIOR RANKING INDEBTEDNESS; ABSENCE OF COVENANT PROTECTION

The Debentures will be subordinate to all Senior Indebtedness and to any
indebtedness of our creditors. The payment of principal and interest on the
Debentures will be subordinated to the Senior Indebtedness of us and to
indebtedness of our trade creditors. The Debentures will also be effectively
subordinate to claims of creditors of our subsidiaries except to the extent we
are a creditor of such subsidiaries ranking at least pari passu with such other
creditors.

The Indentures will not limit the ability of us to incur additional liabilities
(including Senior Indebtedness) or to make distributions, except, in respect of
distributions, where an Event of Default has occurred or would occur and such
default has not been cured or waived. The Indentures do not contain any
provision specifically intended to protect holders of the Debentures in the
event of a future leveraged transaction involving Advantage. However, the
Indentures, among other things, restrict our level of indebtedness, provides
operating investment guidelines, mandates the making of distributions and
specify the nature of our business.

THE ECONOMIC IMPACT ON ADVANTAGE OF CLAIMS OF ABORIGINAL TITLE IS UNKNOWN.

Aboriginal people have claimed aboriginal title and rights to a substantial
portion of western Canada. We are unable to assess the effect, if any, that any
such claim would have on our business and operations.

ENVIRONMENTAL CONCERNS

The oil and natural gas industry is subject to environmental regulation pursuant
to local, provincial and federal legislation. A breach of such legislation may
result in the imposition of fines or issuance of clean-up orders in respect of
AOG or the Properties. Such legislation may be changed to impose higher
standards and potentially more costly obligations on AOG. Although AOG has
established a reclamation fund for the purpose of funding its currently
estimated future environmental and reclamation obligations based upon its
current knowledge, there can be no assurance that we will be able to satisfy its
actual future environmental and reclamation obligations.

Although AOG maintains insurance coverage considered to be customary in the
industry, it is not fully insured against certain environmental risks, either
because such insurance is not available, or because of high premium costs. In
particular, insurance against risks from environmental pollution occurring over
time (compared to sudden and catastrophic damages) is not available.
Accordingly, AOG's properties may be subject to liability due to hazards which
cannot be insured against, or have not been insured against due to prohibitive
premium costs or for other reasons. In such


                                       60


an event, these environmental obligations will be funded out of AOG's cash flow
and could therefore reduce distributable income payable to Unitholders.

Additionally, the potential impact on our operations and business of the
December 1997 Kyoto Protocol, which has now been ratified by Canada, with
respect to instituting reductions of greenhouse gases is difficult to quantify
at this time as specific measures for meeting Canada's commitments have not been
developed.

UNFORESEEN TITLE DEFECTS

Although title reviews are generally conducted prior to any purchase of resource
issuers or resource assets, such reviews do not guarantee that an unforeseen
defect in the chain of title will not arise to defeat AOG's title to certain
assets. A reduction of the distributable cash flow of the Trust and possible
reduction of capital could result from such defects.

Any site reclamation or abandonment costs actually incurred in the ordinary
course of business in a specific period will be funded out of cash flow and,
therefore, will reduce the amounts available for distribution to Unitholders.
Should we be unable to fully fund the cost of remedying an environmental
problem, it might be required to suspend operations or enter into interim
compliance measures pending completion of the required remedy.

DELAY IN CASH DISTRIBUTIONS

In addition to the usual delays in payment by purchasers of oil and natural gas
to the operators of the Properties, and by the operator to the Manager or AOG,
payments between any of such parties may also be delayed by restrictions imposed
by lenders, delays in the sale or delivery of products, delays in the connection
of wells to a gathering system, blowouts or other accidents, recovery by the
operator of expenses incurred in the operation of the Properties, or the
establishment by the operator of reserves for such expenses. Any of these delays
could adversely affect distributions to Unitholders.

FOREIGN CURRENCY EXCHANGE RATES AND INTEREST RATES

World oil prices are quoted in United States dollars and the price received by
Canadian producers is therefore affected by the $US/$Cdn exchange rate that may
fluctuate over time. A material increase in the value of the Canadian dollar,
which occurred in 2004, negatively impacted our net production revenue and may
affect the future value of our reserves as determined by independent evaluations
at this time. The impact is reduced to the extent that we have engaged in, or in
the future will engage in risk management activities related to commodity prices
and foreign exchange rates. We will be subject to unfavourable price changes and
credit risks associated with the counterparties with which it contracts. We have
not entered into any foreign exchange contracts at this time.

Variations in interest rates could result in a significant increase in the
amount we pay to service debt which may result in a decrease in distributions to
Unitholders, as well as impact the market price of the Trust Units on the TSX.

RELIANCE UPON THE MANAGER AND SENIOR EXECUTIVES OF AOG

Unitholders will be dependent upon the management of the Manager and AOG in
respect of the administration and management of all matters relating to the
Properties, the Royalty, the Trust and the Trust Units. The loss of the services
of key individuals who currently comprise our management team could have a
detrimental effect upon us. Investors who are not willing to rely on the
management of the Manager and AOG should not invest in the Trust Units.

RESERVES

The value of the Trust Units will depend upon, among other things, the reserves
attributable to our properties. Estimating reserves is inherently uncertain.
Ultimately, actual production, revenues and expenditures for our properties will
vary from estimates and those variations could be material. The reserve and cash
flow information contained in this renewal annual information form represent
estimates only. Reserves and estimated future net cash flow from our properties
have been independently evaluated at the dates indicated by independent oil and
gas reservoir engineering firms. These firms consider a number of factors and
make assumptions when estimating reserves. These factors and assumptions
include:


                                       61


o        historical production in the area compared with production rates from
         similar producing areas;
o        the assumed effect of governmental regulation;
o        assumptions about future commodity prices, production and development
         costs, severance and excise taxes,
         and capital expenditures;
o        initial production rates;
o        production decline rates;
o        ultimate recovery of reserves;
o        timing and amount of capital expenditures;
o        marketability of production;
o        future prices of oil and natural gas;
o        operating costs and royalties; and
o        other government levies that may be imposed over the producing life of
         reserves.

These factors and assumptions were based upon prices at the date the relevant
evaluations were prepared. If these factors and assumptions prove to be
inaccurate, actual results may vary materially from the reserve estimates. Many
of these factors are subject to change and are beyond our control. For example,
evaluations are based in part upon the assumed success of exploitation
activities intended to be undertaken in future years. Actual reserves and
estimated cash flows will be less than those contained in the evaluations to the
extent that such exploitation activities do not achieve the level of success
assumed in the evaluations. Furthermore, cash flows may differ from those
contained in the evaluations depending upon whether capital expenditures and
operating costs differ from those estimated in the evaluations.

DEPLETION OF RESERVES

We have certain unique attributes that differentiate it from other oil and gas
industry participants. Distributions of distributable income in respect of
Properties, absent commodity price increases or cost effective acquisition and
development activities will decline over time in a manner consistent with
declining production from typical oil, natural gas and natural gas liquids
reserves. AOG will not be reinvesting cash flow in the same manner as other
industry participants. Accordingly, absent capital injections, AOG's initial
production levels and reserves will decline.

AOG's future oil and natural gas reserves and production, and therefore its cash
flows, will be highly dependent upon AOG's success in exploiting its reserve
base and acquiring additional reserves. Without reserve additions through
acquisition or development activities, AOG's reserves and production will
decline over time as reserves are exploited.

To the extent that external sources of capital, including the issuance of
additional Trust Units, become limited or unavailable, AOG's ability to make the
necessary capital investments to maintain or expand its oil and natural gas
reserves will be impaired. To the extent that AOG is required to use cash flow
to finance capital expenditures or property acquisitions, the level of
distributable income will be reduced.

There can be no assurance that we will be successful in developing or acquiring
additional reserves on terms that meet our investment objectives.

RELIANCE UPON THIRD PARTY OPERATORS

Continuing production from a property and marketing of product produced from the
property are dependent to a large extent upon the ability of the operator of the
property. We currently operate properties that represent approximately 85% of
our total daily production. To the extent the operator fails to perform these
functions properly or becomes insolvent, revenue may be reduced.

ENFORCEMENT OF OPERATING AGREEMENTS

Operations of the wells on properties not operated by us are generally governed
by operating agreements, which typically require the operator to conduct
operations in a good and workmanlike manner. Operating agreements generally
provide, however, that the operator will have no liability to the other
non-operating working interest owners for losses sustained or liabilities
incurred, except such as may result from gross negligence or wilful misconduct.
In addition, third-party operators are generally not fiduciaries with respect to
us or our Unitholders. As an owner of working interests in


                                       62


properties we do not operate, we will generally have a cause of action for
damages arising from a breach of such duty. Although not established by
definitive legal precedent, it is unlikely that the Trust or Unitholders would
be entitled to bring suit against third-party operators to enforce the terms of
the operating agreements; thus, Unitholders will be dependent upon us, as owner
of the working interest, to enforce such rights.

CHANGES IN LEGISLATION

There can be no assurance that the treatment of mutual fund trusts will not be
changed in a manner adversely affecting Unitholders. If we cease to qualify as a
"mutual fund trust" under the Tax Act, the Trust Units will cease to be
qualified investments for registered retirement savings plans, registered
education savings plans, deferred profit sharing plans and registered retirement
income funds.

Income tax laws, or other laws or government incentive programs relating to the
oil and gas industry, such as the treatment of mutual fund trusts and resource
taxation, may in the future be changed or interpreted in a manner that adversely
affects us and our Unitholders. Tax authorities having jurisdiction over the
Trust or the Unitholders may disagree with how we calculate our income for tax
purposes or could change administrative practises to the detriment of us or the
detriment of our Unitholders.

We expect that it will continue to qualify as a mutual fund trust for purposes
of the Tax Act. We may not, however, always be able to satisfy any future
requirements for the maintenance of mutual fund trust status. Should the status
of the Trust as a mutual fund trust be lost or successfully challenged by a
relevant tax authority, certain adverse consequences may arise for us and our
Unitholders. Some of the significant consequences of losing mutual fund trust
status are as follows:

o        We would be taxed on certain types of income distributed to
         Unitholders, including income generated by the royalties held by us.
         Payment of this tax may have adverse consequences for some Unitholders,
         particularly Unitholders that are not residents of Canada and residents
         of Canada that are otherwise exempt from Canadian income tax.

o        We would cease to be eligible for the capital gains refund mechanism
         available under Canadian tax laws if it ceased to be a mutual fund
         trust.

o        Trust Units held by Unitholders that are not residents of Canada would
         become taxable Canadian property. These non-resident holders would be
         subject to Canadian income tax on any gains realized on a disposition
         of Trust Units held by them.

o        Trust Units would not constitute qualified investments for registered
         retirement savings plans ("RRSPs"), registered retirement income funds
         ("RRIFs"), registered education savings plans ("RESTs") or deferred
         profit sharing plans ("DPSPs"). If, at the end of any month, one of
         these exempt plans holds Trust Units that are not qualified
         investments, the plan must pay a tax equal to 1% of the fair market
         value of the Trust Units at the time the Trust Units were acquired by
         the exempt plan. An RRSP or RRIF holding non-qualified Trust Units
         would be subject to taxation on income attributable to the Trust Units.
         If an RESP holds non-qualified Trust Units, it may have our
         registration revoked by the Canada Customs and Revenue Agency.

In addition, we may take certain measures in the future to the extent it
believes necessary to ensure that we maintain our status as a mutual fund trust.
These measures could be adverse to certain holders of Trust Units.

INVESTMENT ELIGIBILITY

We will endeavour to ensure that the Trust Units continue to be qualified
investments for registered retirement savings plans, registered education
savings plans, deferred profit sharing plans and registered retirement income
funds. The Tax Act imposes penalties for the acquisition or holding of
non-qualified or ineligible investments and there is no assurance that the
conditions prescribed for such qualified or eligible investments will be adhered
to at any particular time.


                                       63


NATURE OF TRUST UNITS

The Trust Units do not represent a traditional investment in the oil and natural
gas sector and should not be viewed by investors as shares in AOG. The Trust
Units represent a fractional interest in the Trust. As holders of Trust Units,
Unitholders will not have the statutory rights normally associated with
ownership of shares of a corporation including, for example, the right to bring
"oppression" or "derivative" actions. Our primary assets will be the Notes, the
Common Shares, the Royalty and other investments in securities. The price per
Trust Unit is a function of anticipated distributable income, the Properties
acquired by AOG, and the Manager's ability to effect long-term growth in our
value. The market price of the Trust Units will be sensitive to a variety of
market conditions including, but not limited to, interest rates and our ability
to acquire suitable oil and natural gas properties. Changes in market conditions
may adversely affect the trading price of the Trust Units.

The Trust Units are also unlike conventional debt instruments in that there is
no principal amount owing to Unitholders. The Trust Units will have minimal
value when reserves from our properties can no longer be economically produced
or marketed. Unitholders will only be able to obtain a return of the capital
they invested during the period when reserves may be economically recovered and
sold. Accordingly, the distributions received over the life of the investment
may not be equal to or greater than the initial capital investment.

THE TRUST UNITS ARE NOT "DEPOSITS" WITHIN THE MEANING OF THE CANADA DEPOSIT
INSURANCE CORPORATION ACT (CANADA) AND ARE NOT INSURED UNDER THE PROVISIONS OF
THAT ACT OR ANY OTHER LEGISLATION. FURTHERMORE, THE TRUST IS NOT A TRUST COMPANY
AND, ACCORDINGLY, IS NOT REGISTERED UNDER ANY TRUST AND LOAN COMPANY LEGISLATION
AS IT DOES NOT CARRY ON OR INTEND TO CARRY ON THE BUSINESS OF A TRUST COMPANY.

NET ASSET VALUE

The net asset value of our assets from time to time will vary depending upon a
number of factors beyond the control of management, including oil and gas
prices. The trading prices of the Trust Units from time to time is also
determined by a number of factors which are beyond the control of management and
such trading prices may be greater than the net asset value of our assets.

ADDITIONAL FINANCING

In the normal course of making capital investments to maintain and expand our
oil and gas reserves, additional Trust Units are issued from treasury which may
result in a decline in production per Trust Unit and reserves per Trust Unit.
Additionally, from time to time we issue Trust Units from treasury in order to
reduce debt and maintain a more optimal capital structure. To the extent that
external sources of capital, including the issuance of additional Trust Units,
become limited or unavailable, our ability and AOG's ability to make the
necessary capital investments to maintain or expand our oil and gas reserves
will be impaired. To the extent that the Trust and AOG are required to use cash
flow to finance capital expenditures or property acquisitions or to pay debt
service charges or to reduce debt, the level of distributable income will be
reduced.

COMPETITION

There is strong competition relating to all aspects of the oil and gas industry.
There are numerous trusts in the oil and gas industry, who are competing for the
acquisitions of properties with longer life reserves and properties with
exploitation and development opportunities. As a result of such increasing
competition, it will be more difficult to acquire reserves on beneficial terms.
The Trust and AOG also compete for reserve acquisitions and skilled industry
personnel with a substantial number of other oil and gas companies, many of
which have significantly greater financial and other resources than the Trust
and AOG.

RETURN OF CAPITAL

Trust Units will have no value when reserves from the Properties can no longer
be economically produced and, as a result, cash distributions do not represent a
"yield" in the traditional sense and are not comparable to bonds or other fixed
yield securities, where investors are entitled to a full return of the principal
amount of debt on maturity in addition to a


                                       64


return on investment through interest payments. Distributions represent a blend
of a return of Unitholders' initial investment and a return on Unitholders'
initial investment.

Unitholders have a limited right to require us to repurchase their Trust Units,
which is referred to as a redemption right. See "Information Relating to the
Trust - Right of Redemption". It is anticipated that the redemption right will
not be the primary mechanism for Unitholders to liquidate their investment. The
right to receive cash in connection with a redemption is subject to limitations.
Any securities which may be distributed IN SPECIE to Unitholders in connection
with a redemption may not be listed on any stock exchange and a market may not
develop for such securities. In addition, there may be resale restrictions
imposed by law upon the recipients of the securities pursuant to the redemption
right.

REDEMPTION RIGHT

It is anticipated that the redemption right will not be the primary mechanism
for Unitholders to liquidate their investments. Long Term Notes or Redemption
Notes which may be distributed IN SPECIE to Unitholders in connection with a
redemption will not be listed on any stock exchange and no established market is
expected to develop for such Long Term Notes or Redemption Notes. Cash
redemptions are subject to limitations. See "Additional Information Respecting
Advantage Energy Income Fund - Redemption Right".

UNITHOLDER LIMITED LIABILITY

The Trust Indenture provides that no Trust Unitholder will be subject to any
liability in connection with us or our affairs or obligations and, in the event
that a court determines that Unitholders are subject to any such liabilities,
the liabilities will be enforceable only against, and will be satisfied only out
of, such Unitholder's share of our assets.

The Trust Indenture provides that all written instruments signed by or on behalf
of us must contain a provision to the effect that such obligation will not be
binding upon Unitholders personally. Personal liability may also arise in
respect of claims against us that do not arise under contracts, including claims
in tort, claims for taxes and possibly certain other statutory liabilities. The
possibility of any personal liability of this nature arising is considered
unlikely.

FUTURE DILUTION

One of our objectives is to continually add to our reserves through acquisitions
and through development, and because we does not reinvest our cash flow, our
success is in part dependent upon our ability to raise capital from time to
time. Holders of Trust Units may also suffer dilution in connection with future
issuances of Trust Units, whether issued pursuant to a financing or acquisition
or otherwise.

REGULATORY MATTERS

Our operations are subject to a variety of federal and provincial laws and
regulations, including laws and regulations relating to the protection of the
environment.

CONFLICTS OF INTEREST

The directors and officers of the Corporation are engaged in and will continue
to be engaged in other activities in the oil and natural gas industry and, as a
result of these and other activities, the directors and officers of the
Corporation may become subject to conflicts of interest. The ABCA provides that
in the event that a director has an interest in a contract or proposed contract
or agreement, the director shall disclose his interest in such contract or
agreement and shall refrain from voting on any matter in respect of such
contract or agreement unless otherwise provided under the ABCA. To the extent
that conflicts of interest arise, such conflicts will be resolved in accordance
with the provisions of the ABCA.

                             ADDITIONAL INFORMATION

Additional information, including directors' and officers' remuneration and
indebtedness, principal holders of securities and interests of insiders in
material transactions, where applicable, is contained in our information

The independent reserves evaluation committee of the Trust has

         (b)      reviewed the Trust's procedures for providing information to
                  Sproule;

         (c)      met with Sproule to determine whether any restrictions
                  affected Sproule's ability to report without reservation; and

         (d)      reviewed the reserves data with management and the independent
                  qualified reserves evaluator.

The independent reserves evaluation committee has reviewed the Trust's
procedures for assembling and reporting other information associated with oil
and gas activities and has reviewed that information with management. The board
of directors has, on the recommendation of the independent reserves evaluation
committee, approved

         (e)      the content and filing with securities regulatory authorities
                  of the reserves data and other oil and gas information;

         (f)      the filing of the report of the independent qualified reserves
                  evaluator on the reserves data; and

         (g)      the content and filing of this report.

Because the reserves data are based upon judgments regarding future events,
actual results will vary and the variations may be material.

                             REPORT ON RESERVES DATA

To the board of directors of Advantage Energy Income Fund (the "Trust"):

1.       We have evaluated the Trust's reserves data as at December 31, 2004.
         The reserves data consist of the following:

         (a)      (i)      proved and proved plus probable oil and gas reserves
                           estimated as at December 31, 2004 using forecast
                           prices and costs; and

                  (ii)     the related estimated future net revenue; and

         (b)      (i)      proved oil and gas reserves estimated as at December
                           31, 2004 using constant prices and costs; and

                  (ii)     the related estimated future net revenue.

2.       The reserves data are the responsibility of the Trust's management. Our
         responsibility is to express an opinion on the reserves data based upon
         our evaluation.

         We carried out our evaluation in accordance with standards set out in
         the Canadian Oil and Gas Evaluation Handbook (the "COGE Handbook")
         prepared jointly by the Society of Petroleum Evaluation Engineers
         (Calgary Chapter) and the Canadian Institute of Mining, Metallurgy &
         Petroleum (Petroleum Society).

3.       Those standards require that we plan and perform an evaluation to
         obtain reasonable assurance as to whether the reserves data are free of
         material misstatement. An evaluation also includes assessing whether
         the reserves data are in accordance with principles and definitions
         presented in the COGE Handbook.

4.       The following table sets forth the estimated future net revenue
         attributed to proved plus probable reserves, estimated using forecast
         prices and costs and calculated using a discount rate of 10 percent,
         included in the reserves data of the Trust evaluated by us for the year
         ended December 31, 2004, and identifies the respective portions thereof
         that we have audited, evaluated and reviewed and reported on to the
         Trust's board of directors:



                                                                Location of           Net Present Value of Future Net Revenue

5.       In our opinion, the reserves data respectively evaluated by us have, in
         all material respects, been determined and are in accordance with the
         COGE Handbook.

6.       We have no responsibility to update our reports referred to in
         paragraph 4 for events and circumstances occurring after its
         preparation date.

7.       Because the reserves data are based upon judgements regarding future
         events, actual results will vary and the variations may be material.
