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

Certain  statements  contained in this annual information form, and in certain
documents  incorporated  by  reference  into  this  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  annual
information form should not be unduly relied upon. These statements speak only
as of the date of this annual  information form or as of the date specified in
the documents  incorporated by reference into this annual information form, as
the case may be.

In particular, this 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 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 annual  information  form and the documents  incorporated by
reference herein are expressly qualified by this cautionary statement.  Except
as required by law,  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 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 our  wholly-owned  oil and  natural  gas
exploitation and development  company. 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 company
wholly-owned  by us.  Search and  AcquisitionCo  amalgamated  and continued as
"Search Energy Corp.". On July 26, 2001, Search acquired all of the issued and
outstanding  shares of Due West Resources Inc. ("DUE WEST").  Effective August
1, 2001,  Search and Due West  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"),  after
which  Best  Pacific  assigned  all of its  assets  to AOG and  dissolved.  On
December 2, 2003,  AOG  acquired all of the issued and  outstanding  shares of
MarkWest Resources Canada Corp.  ("MARKWEST").  MarkWest  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.
Effective February 1, 2006, Advantage ExchangeCo Ltd. amalgamated with AOG.

In accordance with the Management  Agreement,  Advantage Investment Management
Ltd.  (the  "MANAGER")  agreed to act as manager of the Trust and of 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 of 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

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 (the "AOG BOARD OF  DIRECTORS")  and the Manager
has the right to designate two of such directors.


                      GENERAL DEVELOPMENT OF THE BUSINESS

2003

On July 8, 2003, we completed the issue, by way of short form  prospectus,  of
$30,000,000   aggregate   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  2,  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 8.25%
convertible  unsecured  subordinated  debentures,  which debentures  mature on
February 1, 2009 and are convertible into Trust Units at $16.50 per Trust Unit
(the "8.25%  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.


                                      8


2004

On September 15, 2004, we completed an issue, by way of short form prospectus,
of 3,500,000 Trust Units and $75,000,000  aggregate  principal amount of 7.50%
convertible  unsecured  subordinated  debentures (the "7.50%  DEBENTURES") and
$50,000,000   aggregate  principal  amount  of  7.75%  convertible   unsecured
subordinated  debentures  (the "7.75%  DEBENTURES")  to partially  finance the
$186,000,000 (before closing adjustments) acquisition of certain petroleum and
natural  gas  properties  and  related  assets (the  "ACQUIRED  ASSETS")  from
Anadarko (the "ASSET ACQUISITION").  The 7.50% Debentures mature on October 1,
2009 and are convertible into Trust Units at a price of $20.25 per Trust Unit.
The 7.75% Debentures mature on December 1, 2011 and are convertible into Trust
Units at a price of  $21.00  per Trust  Unit.  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.

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.  As a result of this transaction,  we paid
total cash  consideration  of  $34,000,000,  issued  3,666,286 Trust Units and
issued 1,450,030 AOG exchangeable shares.

2005

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.  The net  proceeds  of the  offering  were used to pay down debt
incurred in the Defiant Acquisition,  for our 2005 capital expenditure program
and for general corporate purposes.

On December 9, 2005, the Trust Units were listed and posted for trading on the
New York Stock  Exchange  (the  "NYSE")  under the trading  symbol  "AAV".  We
believe  the listing on the NYSE will  result in  improved  liquidity  for all
Unitholders,  greater access to the U.S. capital markets, and improved cost of
capital for future acquisitions.

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 2006 financial year.

                  DESCRIPTION OF OUR BUSINESS AND OPERATIONS

ADVANTAGE ENERGY INCOME FUND

We are a limited purpose trust and are restricted to:

1.   investing in the Initial Permitted Securities, the Permitted Investments,
     Subsequent  Investments and such other  securities and investments as AOG
     may determine,  provided that under no  circumstances  shall the Trustee,
     AOG or the Manager  purchase or authorize  the purchase of any  security,
     asset or  investment  (collectively  a  "Prohibited  Investment")  on our
     behalf  or using any of our  assets or  property  which  are  defined  as
     "foreign property" under subsection 206(1) of the INCOME TAX ACT (Canada)
     ("TAX ACT") or are a "small business security" as that expression is used
     in Part LI of the  Regulations  to the Tax Act or would  result in us not
     being  considered  either a "unit  trust" or a "mutual  fund  trust"  for
     purposes of the Tax Act at the time such investment was made;

2.   disposing of any part of the Trust Fund,  including,  without limitation,
     any Permitted Investments;

3.   acquiring  the  Royalty  and  other  royalties  in  respect  of  Resource
     Properties;


                                      9


4.   temporarily   holding   cash,   and  Permitted   Investments   (including
     investments  in AOG) for the purposes of paying Trust  expenses and Trust
     liabilities,  paying  amounts  payable  by  us  in  connection  with  the
     redemption of any Trust Units, and making distributions to Unitholders;

5.   acquiring or investing in  securities  of AOG or any other  subsidiary of
     ours to fund the acquisition,  development,  exploitation and disposition
     of all types of  petroleum  and natural gas  related  assets,  including,
     without  limitation,  facilities of any kind and whether effected through
     the  acquisition of assets or the  acquisition of shares or other form of
     ownership interest in any entity, the substantial  majority of the assets
     of which are comprised of like assets;

6.   undertaking  such other  business and activities  including  investing in
     securities as shall be approved by AOG from time to time provided that we
     shall not  undertake  any  business  or  activity  which is a  Prohibited
     Investment (as defined in the Trust Indenture);

and to pay the costs,  fees and expenses  associated  therewith or  incidental
thereto.

In  accordance  with the  terms of the  Trust  Indenture,  we will  make  cash
distributions  to our  Unitholders of the interest income earned from the Long
Term Notes and Medium Terms Notes and  principal  repayments,  royalty  income
earned on the Royalty,  dividends (if any)  received on, and amounts,  if any,
received on redemption of, Common Shares and Preferred Shares,  and income and
distributions  received  from any  Permitted  Investments  after  expenses and
capital  expenditures,   any  cash  redemptions  of  Trust  Units,  and  other
expenditures.  See "Additional  Information Respecting Advantage Energy Income
Fund - Cash Distributions".

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.  As a practice, AOG may manage the risk associated with changes
in commodity prices by entering into oil or natural gas hedges related only to
specific acquisition or project economics.  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 AOG Board of  Directors  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 AOG  Board  of
Directors.

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.

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
issuance of  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

Our  properties  are spread  geographically  throughout  the Western  Canadian
Sedimentary  Basin.  This  sedimentary  basin covers a large  portion of the 4
western Canadian provinces,  with the majority of our properties  concentrated
in Alberta,  along with a few in northeast British Columbia and also southeast
Saskatchewan.  These  properties  produce  from  a  variety  of  various  aged
geological formations and reservoirs. We have managed our portfolio so that we
now  operate  more than 85% of our  properties.  This allows us to control the
nature  and  timing of the  capital  investments  necessary  to  maximize  the
potential in developing these assets.

Our  properties  can be  divided  on  the  broad  basis  of  commodity  and of
production  type.  Light  or  medium  gravity  oil  accounts  for  35%  of our
production  and 33% of our reserves.  A further 65% of  production  and 67% of
reserves are natural gas.

SHALLOW GAS PROPERTIES

A significant  portion of our production  comes from shallow gas properties at
Medicine Hat, Bantry, Shouldice and Wainwright. These projects are all located
in southern  Alberta and occur between 500 and 1,200 meters of depth.  Typical
of shallow gas,  these  properties  are resource  plays which  require a large
number of wells to extract the very large in place  reserves at relatively low
per well production rates. As a result, they have a long production life (long
reserve  life index or RLI).  These  reservoirs  consist  of low  permeability
strata, requiring fracture stimulation to enhance and induce productivity. The
wells are gathered by an extensive  network of low  pressure  pipelines  which
feed into large central gas compression  facilities.  All of these  properties
have been downspaced to allow for multiple gas wells per section, ranging from
just 2 per  section at  Wainwright  to the  current 16 per section at Medicine
Hat.

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  approximately 5.2 MMcf/d of natural gas. In 2002 and 2003,  several
recompletions along with an additional 164 wells were


                                      19


drilled.  Late in 2003 an  additional  57 wells were drilled and  completed in
2004. In 2004 a further 68 wells were drilled and completed.  Late in 2005 and
early in 2006, 30 low  production  rate wells were  recompleted.  As a result,
current  production from this property is 15.3 MMcf/d from  approximately  385
wells. No new wells were added in 2005.  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 or 2005.

Sproule  evaluated  our reserves in the area and  assigned  58.7 bcf of proved
natural gas reserves and 9.9 bcf of probable reserves.  As such, this property
is our largest property on an assigned reserves basis.

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.  This property was acquired in November
2003.  During 2004 we drilled 48 (gross) wells.  An additional 5 (gross) wells
were drilled during 2005. Of these 5 wells, one has been abandoned. 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  1,286
boe/d.  Additional compression capacity was added in the first quarter of 2004
to handle  incremental  volumes.  In 2005, a  rationalization  of  compression
facilities was undertaken to reduce future operating costs and free up capital
from surplus compression equipment.

The Sproule  Report  assigns 11.7 bcf of proven  natural gas reserves and 18.7
Mbbls of  proven  NGL  reserves  to this  property.  In  addition,  6.6 bcf of
probable  natural gas reserves  and 10.6 Mbbls of probable  NGL reserves  have
been assigned to this property.

SHOULDICE, ALBERTA

The  Shouldice  area  of  southern  Alberta  is  located  approximately  50 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
in the area.  Much of this acreage is  downspaced  to  accommodate  additional
drilling.  Current  natural  gas  production  of  approximately  4.1 MMcf/d is
produced on a  co-mingled  basis from the Medicine  Hat  Formation  sands with
various Belly River Formation sands.

During 2003, 20 net wells were added to the existing 70 producing wells.  Both
natural gas and crude oil are produced and gathered  through our facilities of
varying working interests.  An additional 4 MMcf/d of new compression capacity
was added in 2004 to handle additional  production.  In 2005, one new well was
drilled and produces at an approximate rate of 500 Mcf/d. Additional drilling,
potentially up to 10 wells, is planned on this property in 2006.

The Sproule Report assigns 9.1 bcf of proven natural gas reserves and 90 Mbbls
of  proven  crude  oil and  NGLs to this  property.  In  addition,  3.8 bcf of
probable  natural  gas  reserves  and 39 Mbbls of  probable  crude oil and NGL
reserves have been assigned to this property.

WAINWRIGHT, ALBERTA

The Wainwright property is located  approximately 175 kilometres  southeast of
the City of Edmonton.  We have  varying  working  interests  in this  property
averaging 85% in  approximately  175 sections of land.  Current net production
from the property is  approximately  4.3 MMcf/d natural gas and 24 bbls/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. No drilling  occurred on this property in
2004 and 2005.


                                      20


Sproule  evaluated our proved reserves in the Wainwright area and assigned 8.1
bcf of natural gas.  Probable  reserves in this area were evaluated by Sproule
at 2.3 bcf of natural gas.

CONVENTIONAL OIL AND NATURAL GAS PROPERTIES

Conventionally  produced oil and gas properties constitute the majority of our
property  portfolio.  Some of these  properties  produce  only natural gas or,
occasionally,  only oil.  In most  instances  both  products  co-exist  in the
production  and we operate in excess of 80% of these  properties.  In 2005 the
bulk  of our  capital  expenditures  occurred  on  these  properties,  and was
significantly spread out amongst many individual projects.

NEVIS, ALBERTA

The Nevis  property  is  situated  60 km east of Red Deer.  Nevis  consists of
approximately  55 sections of land with an average  working  interest over 80%
and is 95% 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. Crude oil quality to date has been exceptional ranging
for the most part between 35o and 42o API. Natural gas is gathered through our
pipelines  and  processed at a third party  plant.  Oil is trucked from single
well batteries.

In 2005,  13  horizontal  wells and 4  vertical  wells were  drilled.  Current
production is approximately 2,000 boe/d. Currently the pool is spaced to allow
for 4 wells per section. Currently, the property is being reviewed to evaluate
the potential  waterflood of this reservoir to increase future  recoveries and
to evaluate future downspacing.

The Sproule  Report  assigns 17.6 bcf of proven natural gas reserves and 3,693
Mbbls of proven crude oil and NGL reserves to this property. In addition,  5.5
bcf of probable natural gas reserves and 1,285 Mbbls of probable crude oil and
NGL reserves have been assigned to this property.

CHIP LAKE, ALBERTA

The Chip Lake property is located 125 kilometers west of the City of Edmonton.
The  property  produces  light  crude  oil  (37o  API)  with  associated  gas.
Production at the end of 2005 is  approximately  490 boe/d.  This property was
acquired in December 2004.  Prior to the  acquisition,  the previous owner had
constructed a central sour oil and water handling facility without appropriate
Energy  Utilities  Board  ("EUB")  approval.  We  are  involved  in  extensive
discussion with the EUB and public stakeholders to resolve this issue in 2006.
Currently  the property  will  continue to produce from single well  batteries
under maximum rate limitation allowables until the issues are resolved.

The Sproule  Report has assigned  proved  reserves for this  property of 2,128
Mbbls of crude oil and NGL's and 1.9 Bcf of natural  gas. In  addition,  2,648
Mbbls of  probable  crude oil and NGL's and 1.8 Bcf of  probable  natural  gas
reserves have been assigned to the property.

SUNSET/VALLEYVIEW, 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 were acquired in
December 2004 by virtue of the acquisition of Defiant.

SUNSET A - Production is predominantly  oil at  approximately  32oAPI to date.
This pool is unitized and we have a 70% working  interest in the unit which we
also operate.  During 2005,  two wells were drilled and spaced across the unit
which evaluated the viability of moving the full pool onto a downspaced basis.
Plans are to drill an additional 14 wells in 2006. Current net production from
the Sunset A unit is 240 bbls/d of crude oil and 240 Mcf/d of natural gas. 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.


                                      21


SUNSET B - Production from this Montney reservoir is predominantly natural gas
although there is a thin oil column. Oil gravity is light at 33oAPI. We have a
100% interest in this pool.  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 1.9
MMcf/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. No wells were drilled in 2005 and plans
for 2006 are being investigated.

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, NGLs and
light oil from both  properties are processed.  We have a 93% average  working
interest in the pool.  One new well was drilled in 2005 and there are plans to
drill 2 new wells in 2006. Production at Valleyview is essentially all natural
gas with current rates of approximately 3.0 MMcf/d. All wells require fracture
stimulation  to  bring  them on  production  and cost  approximately  $750,000
drilled, completed and tied-in.

For the three  properties,  Sunset A,  Sunset B and  Valleyview,  the  Sproule
Report  assigns  19.8 bcf of proven  natural gas  reserves  and 2,096 Mbbls of
proven crude oil and NGL reserves to this property.  In addition,  13.2 bcf of
probable  natural gas reserves  and 2,274 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 just west 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. Historically,  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 North Pine Charlie  Lake oil pool.  The area  includes  12,000
gross (9,176 net) acres of undeveloped land. Current production from this area
is 3.2 MMcf/d of natural gas and 177 bbls/d of light oil and NGLs.

Sproule  evaluated  our proved  reserves in the area and assigned  10.9 bcf of
natural  gas and 561  Mbbls of crude  oil and NGLs.  In  addition,  4.2 bcf of
probable  natural gas  reserves  and 265 Mbbls of probable  crude oil and NGLs
reserves have been assigned to this property.

SOUTHEAST SASKATCHEWAN

This area consists of a host of individual properties all within the Williston
Sedimentary  Basin in the  southeast  corner of  Saskatchewan.  We operate the
majority of this  production  at 100% which comes  principally  from the major
properties  being the Ordovician Red River Formation oil at Midale,  Hardy and
Froude,   Devonian  Winnipegosis  Formation  oil  at  Steelman  and  oil  from
Mississippian Midale/Frobisher Formations at Steelman, Weyburn and Workman. We
drilled two multi-leg horizontal Frobisher wells at Steelman in 2005. Also one
vertical Red River oil well and a vertical  Mannville water injector well were
drilled at Froude. Numerous well re-activations and re-entries were undertaken
in 2005 in several pools.  Production from Saskatchewan,  all light crude oil,
was 1,720 bbls/d.  Southeast  Saskatchewan  will continue to be an active area
for us with additional  drilling and/or side track re-entries  planned in 2006
at Hardy,  Midale and  Steelman.  The Workman  property is being  reviewed for
unitization and waterflood.

Sproule  evaluated our reserves in the area and assigned 3,556 Mbbls of proven
crude oil.  Probable  reserves in this area were evaluated by Sproule at 2,940
Mbbls of crude oil.

BRAZEAU RIVER, ALBERTA

The Brazeau River property is located  approximately 50 km west of the town of
Drayton Valley. 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


                                      22


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.  In 2005,  this property  experienced  numerous  production  issues
related to various delays in servicing the wells by the operator. These issues
have been resolved and production  has been  restored.  Current net production
from the property is approximately  2.5 MMcf/d natural gas and 310 bbls/d NGLs
and crude oil.

Sproule  evaluated our proved  reserves in the Brazeau River area and assigned
3.0 bcf of natural gas and 329 Mbbls of crude oil and NGLs.  Probable reserves
in this area were evaluated by Sproule at 2.5 bcf of natural gas and 220 Mbbls
of crude oil and NGLs.

OPEN LAKE (WILLESDEN GREEN), ALBERTA

The Willesden Green property is located  approximately 35 km north of the Town
of Rocky  Mountain  House.  The property was acquired in the package of assets
purchased  from  Anadarko  in 2004.  We  operate  and have in  excess of a 90%
working  interest  in the  Willesden  Green  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.  Net current  production from
the property is  approximately  3.2 mmcf/d natural gas and 432 bbls/d NGLs and
crude oil.

Sproule evaluated our proved reserves in the Willesden Green area and assigned
5.5 bcf of natural gas and 660 Mbbls of crude oil and NGLs.  Probable reserves
in this area were evaluated by Sproule at 2.4 bcf of natural gas and 335 Mbbls
of crude oil and NGLs.

We expect that rights to explore,  develop and exploit 85,227 net acres of our
undeveloped  land  holdings  will  expire  by  December  31,  2006.  The  land
expirations do not consider our 2006 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.


FORWARD CONTRACTS

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 in recent years.  Such prices are primarily  determined
by  economic,  and in the case of oil prices,  political  factors.  Supply and
demand  factors,  as  well  as  weather,  general  economic  conditions,   and
conditions  in other oil and  natural  gas  regions of the world  also  impact
prices.  Any upward or downward  movement in oil and natural gas prices  could
have  an  effect  on  our  financial   condition,   thus  impacting  the  cash
distributions made to Unitholders.

In the past,  we have entered into short term  hedging  agreements  which have
limited  the risk  associated  with  downward  changes  in  commodity  prices.
However, these agreements have also meant that we have foregone the benefit of
any price increases.  As a future practice,  we may manage the risk associated
with  changes in  commodity  prices by entering  into oil or natural gas price
hedges. These hedging activities could expose us to losses or gains.  However,
such oil or natural  gas price  hedges  will only be entered  into on specific
acquisitions  and  projects.  To the extent that we engage in risk  management
activities  related to  commodity  prices,  we will be subject to credit  risk
associated  with the parties with which we contract.  This credit risk will be
mitigated by entering into contracts with only stable and creditworthy parties
and through the frequent review of our exposure to these entities entities.

We currently do not have any hedge contracts or forward commitments in place.

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 2,433
(gross)  producing and non-producing  wells.  Costs to abandon and reclaim the
producing wells totals $45.8 million ($11.6 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 $48.2 million ($3.5 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.


                                      24


Abandonment  and  reclamation  costs  included  in the  estimate of future net
revenue for the next three  years are $0.6  million in 2006,  $0.8  million in
2007 and $1.3 million in 2008.

TAX HORIZON

In 2005, 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 taxation year. As a result of legislation in 2003,  capital
taxes are to be gradually eliminated over the next four years.

In our  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  2005
distributions,  40% were  taxable  to the  Canadian  Unitholders  and 60% were
deemed a return of capital. For U.S. Unitholders,  2005 distributions were 44%
taxable and 56% were deemed a return of capital.

CAPITAL EXPENDITURES

The following tables summarize  capital  expenditures  (including  capitalized
general and  administrative  expenses)  related to our activities for the year

Subject to, among other things,  the availability of drilling rigs and weather
that permits  access to drill sites,  in 2006, we plan to drill,  complete and
tie-in  96.2  net  wells  and   recomplete  an  additional   52.0  net  wells.
Approximately  30 net wells will be drilled at  Medicine  Hat, 14 net wells at
Nevis,  10 net wells at Sunset and 7 net wells in the Red Deer Area.  The well
recompletions   will  be  focussed  in  Medicine   Hat,   Wainwright   and  SE
Saskatchewan.

(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 set forth above 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 &

     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

          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:


                                      27


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

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

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

     "NET" means:

     (i)  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;

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

     (k)  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.


                                      28


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

     (c)  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.

     (d)  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  15% 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.


                                      29


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 2006 by the  renegotiation or
termination of contracts or subcontracts.

ENVIRONMENTAL CONSIDERATIONS

We are pro-active in our approach to environmental 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, 2005,  we employ 80  full-time  employees,  68 of which are
located in the head office and 12 of which are  located in the field.  We also
employ 9 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, 2005,  57,846,324 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 the AOG 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.

The price per Trust Unit is a function  of  anticipated  distributable  income
from  AOG and the  combined  ability  of the AOG  Board of  Directors  and the
Manager to effect long term growth in the value of the Trust. The market price
of the  Trust  Units


                                      30


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, 2005, AOG had 104,672 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
AOG Board of Directors  in its sole  discretion  from time to time,  such cash
dividends as may be declared thereon by the AOG 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
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.


                                      31


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 AOG Board of Directors  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 AOG  Board  of  Directors  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.

Pursuant to the  provisions  of the Trust  Indenture  all income earned by the
Trust in a fiscal year, not previously  distributed in that fiscal year,  must
be distributed to Unitholders of record on December 31. This excess income, if
any, will be allocated to  Unitholders  of record at December 31 but the right
to receive this income,  if the amount if not determined and declared  payable
at December 31, will trade with the Trust Units until  determined and declared
payable in  accordance  with the rules of the Toronto Stock  Exchange.  To the
extent  that a  Unitholder  trades  Trust  Units in this  period  they will be
allocated  such  income  but will  dispose  of their  right  to  receive  such
distribution.

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


                                      32


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.

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.


                                      33


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  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 26,
2006.

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 AOG Board of  Directors  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 AOG Board of
Directors 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  was 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


                                      34


resign upon providing 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.

DELEGATION OF AUTHORITY, ADMINISTRATION AND TRUST GOVERNANCE

The AOG Board of  Directors  has  generally  been  delegated  our  significant
management decisions and the Manager has been retained to administer the Trust
on behalf of the Trustee. In particular,  the Trustee has delegated to the AOG
Board of Directors  responsibility  for any and all matters relating to, among
other  things:  (a) any offering of our  securities,  including:  (i) ensuring
compliance with all applicable  laws; (ii) all matters relating to the content
of any offering documents,  the accuracy of the disclosure  contained therein,
and the certification  thereof;  (iii) all matters concerning any subscription
agreements  or  underwriting  or agency  agreements  providing for the sale of
Trust Units or securities  convertible for or exchangeable into Trust Units or
rights to Trust  Units;  and (iv) all  matters  concerning  the  adoption of a
unitholder rights plan; (b) all matters concerning the terms of, and amendment
from time to time of,  material  contracts;  (c) all  matters  relating to the
redemption of Trust Units; (d) the  determination  of any Distribution  Record
Date other than the last day of each  calendar  month and the  payment of cash
distributions  to Unitholders;  (e) the  determination of any borrowings under
the  Trust  Indenture;  (f)  our  acquisition  of  Permitted  Investments  and
Subsequent Investments and the negotiation of agreements respecting Subsequent
Investments;  (g)  maintaining  our books and  records  and  providing  timely
reports  to  Unitholders;  (h) our  financial  statements  and  the  financial
statements  of AOG;  (i) the  continued  listing  of our  Trust  Units  on any
exchange and to maintain  our status as a reporting  issuer,  including  press
releases and material change reports as required by the continuous  disclosure
requirements  of  applicable  securities  legislation;  and  (j)  the  Initial
Permitted Securities.  Unitholders are entitled to elect a majority of the AOG
Board of Directors pursuant to the terms of the Shareholder Agreement. Subject
to the  ultimate  authority of the AOG Board of  Directors,  AOG and the Trust
will be managed by the Manager.  For more  information  as to the AOG Board of
Directors,  see "Additional  Information Respecting Advantage Oil & Gas Ltd. -
Management of AOG".

DECISION-MAKING

Although the Manager will provide certain advisory and management  services to
us pursuant  to the  Management  Agreement,  the AOG Board of  Directors  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 AOG Board of  Directors.  In addition,  the Trustee has  delegated
certain matters to the AOG Board of Directors,  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 AOG
Board of Directors on our behalf. The AOG Board of Directors 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


                                      35


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

AMENDMENTS TO THE TRUST INDENTURE

66 2/3% of the votes  cast at a meeting  of our  Unitholders  called  for such
purpose.

The  Trustee  may,  without  the  approval of the  Unitholders,  make  certain
amendments to the Trust Indenture, including amendments:

1.   for the purpose of ensuring  continuing  compliance  with applicable laws

     over the Trust;

     result of changes in taxation laws; and

     Material Contracts (as such term is defined in the Trust Indenture) which
     are,  in the  opinion of the  Trustee,  necessary  or  desirable  and not
     prejudicial to the Unitholders.

TERM OF THE TRUST AND SALE OF SUBSTANTIALLY ALL ASSETS

to 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 AOG
Board of Directors,  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

legislation  or by a  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

DISTRIBUTION POLICY

It is anticipated that income received 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.  AOG is the sole holder of
the issued and outstanding  Common Shares.  There are no Non-Voting  Shares or
Preferred  Shares issued and  outstanding.  AOG is 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 AOG Board of Directors
and  subject  to  applicable  legal  restrictions,  entitled  to  receive  any
dividends  declared by the AOG 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

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
AOG 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, 2005, AOG had 104,672 Exchangeable Shares outstanding.  The
Exchangeable Shares were issued in connection with our acquisition of Defiant.

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.



                                       40


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  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.

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,  approval of the AOG 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 AOG 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 AOG  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 AOG  Board of
Directors.  Under the terms of the Shareholder Agreement,  the Manager has the
right to designate two directors to be elected to the AOG Board of Directors.

The Manager is paid fees for  providing  all of the  services in items 1 and 2

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 AOG Board of Directors.

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


                                      45


expenditures  are 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 AOG Board of Directors 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 60th 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 AOG  Board of  Directors)  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  December 30, 2005, such fees
are allocated by the Manager, subject to the discretion of the Manager, on the
following basis:

                Manager
                          Operating Fee                    60%
                         Termination Fee                   60%
                         Performance Fee                   40%
                Employees of AOG
                         Operating Fee                     40%
                         Termination Fee                   40%
                         Performance Fee                   60%

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 AOG Board of Directors.

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 AOG Board
of Directors 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 AOG  Board of  Directors  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 AOG Board of  Directors  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 AOG Board of  Directors  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 AOG Board of  Directors,  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 AOG Board of Directors,  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


                                      53


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 AOG Board of  Directors on April 30, 2002 and amended in April
2003, April 2004, June 2005, August 2005, October 2005 and March 2006:

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.
("AOG") in fulfilling its responsibilities by reviewing: the financial reports
and other financial  information provided by Advantage Energy Income Fund (the
"Trust")  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  endeavour  to  encourage  continuous
improvement  of, and should  endeavour  to foster  adherence  to, the  Trust's
policies,  procedures  and practices at all levels.  In performing its duties,
the external auditor is to report directly to the Audit  Committee.  The Audit
Committee's primary objectives are:

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 assist the  Board's  oversight  of the  auditor's  qualifications  and
     independence;

4.   To  assist  the  Board's  oversight  of the  credibility,  integrity  and
     objectivity of financial reports;

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

6.   To assist the  Board's  oversight  of the  performance  of  Corporation's
     internal audit function and independent auditors; and

7.   To assist the Board's  oversight  of the  Corporation's  compliance  with
     legal and regulatory requirements.

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
"independent"  (as such term is defined in (a) Multilateral  Instrument 52-110
- -- Audit  Committees  ("MI  52-110") and (b) Section  303A.02 of the Corporate
Governance  Rules of the New York Stock  Exchange).  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
definition  is set forth in Schedule  "A"  attached  hereto.  Audit  Committee
members  may  enhance  their   familiarity  with  finance  and  accounting  by
participating  in  educational  programs  conducted by the Trust or an outside
consultant.  In addition, at least one member of the Audit Committee must have
accounting or related  financial  management  expertise,  as the Corporation's
Board of Directors interprets such qualification in its business judgment.

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


                                      54


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.

In  connection  with the election of the members of the Audit  Committee,  the
Board will  determine  whether any  proposed  nominee for the Audit  Committee
serves on the Audit  Committees  of more than three public  companies.  To the
extent  that any  proposed  nominee  of the  Corporation  serves  on the Audit
Committees  of more  than  three  public  companies,  the  Board  will  make a
determination  as to  whether  such  simultaneous  services  would  impair the
ability  of such  member  to  effectively  serve  on the  Corporation's  Audit
Committee and will disclose such  determination  in the  Corporation's  annual
information  circular and annual report on Form 40-F filed with the Securities
and Exchange Commission.

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,  internal  auditors  (if  any)  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 Section IV.4 below.  The Audit Committee should also meet with management
and  independent  auditors  on an annual  basis to review and  discuss  annual
financial statements and the management's discussion and analysis of financial
conditions and results of  operations.  Attached as Schedule "B" is an example
of an annual meeting schedule/agenda.

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.

     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
     policies and procedures for the engagement of non-audit services if:

     (a)  the  pre-approval  policies  and  procedures  are detailed as to the
          particular service;

     The Audit Committee will satisfy the  pre-approval  requirement set forth
     in this paragraph 22 if:

     (d)  the  aggregate  amount  of all  non-audit  services  that  were  not
          pre-approved is reasonably expected to constitute no more than 5% of
          the  total  amount  of fees  paid by the  Trust  and its  subsidiary
          entities  to the  auditors  during  the  fiscal  year in  which  the
          services are provided;

     (e)  the  Trust or the  subsidiary  entity,  as the case may be,  did not
          recognize  the  services  as  non-audit  services at the time of the
          engagement;

     (f)  the  services  are  promptly  brought to the  attention of the Audit
          Committee  and approved,  prior to  completion of the audit,  by the
          Audit  Committee or by one or more of its members to whom  authority
          to grant such approvals has been  delegated by the Audit  Committee;
          and

23.  Review,  set and approve hiring policies relating to staff of current and
     former auditors.

28.  Request  reporting to the Audit  Committee by each of management  and the
     independent   auditors  of  any   significant   judgments   made  in  the
     management's preparation of the financial statements and the view of each
     group as to appropriateness of such judgments.

29.  Following  completion of the annual audit, review separately with each of
     management  and the  independent  auditors any  significant  difficulties
     encountered during the course of the audit, including any restrictions on
     the scope of work or access to required information.

30.  Review any significant disagreements among management and the independent
     auditors in connection with the preparation of the financial statements.

                                 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 annual
information form.


                                      58


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.

OIL AND NATURAL GAS PRICES

AOG's  results of  operations  and  financial  condition  and 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    global energy  policy,  including the ability of OPEC to set and maintain
     production levels and prices for oil;
o    political  conditions  throughout  the  world,   including  the  risk  of
     hostilities in the Middle East and global terrorism;
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.

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  2005 averaging  US$56.61 WTI as
compared to an average of US$41.43 WTI in 2004, an increase of 37%.

AECO monthly index prices averaged  $8.49/Mcf in 2005 as compared to $6.79/Mcf
in 2004,  an increase of 25%. 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.

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


                                      59


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.

OPERATING COSTS AND PRODUCTION DECLINES

Higher  operating  costs for the  underlying  properties  of AOG will directly
decrease  the amount of cash flow  received by us and,  therefore,  may reduce
distributions   to  our   Unitholders.   Electricity,   chemicals,   supplies,
reclamation  and  abandonment  and labour  costs are a few of AOG's  operating
costs that are susceptible to material fluctuation.

The level of production  from AOG's  existing  properties may decline at rates
greater than  anticipated due to unforeseen  circumstances,  many of which are
beyond AOG's  control.  A significant  decline in  production  could result in
materially  lower  revenues  and cash flow and,  therefore,  could  reduce the
amount available for distributions to Unitholders.

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.

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 AOG Board of Directors 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


                                      60


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.

DEBT SERVICE

AOG has  credit  facilities  in the  amount  of  $355,000,000.  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.

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 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.


                                      61


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,  accounting  delays,  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 $Cdn/$US  exchange rate that
may  fluctuate  over time.  A material  increase in the value of the  Canadian
dollar, which occurred in 2005, negatively impacted our net production revenue
and may affect the future value of our reserves as determined  by  independent
evaluations at this time. The Canadian dollar  strengthened in 2005 to average
$0.83 US/Cdn  compared to $0.77  US/Cdn in 2004.  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 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:

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;


                                      62


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 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.



                                      63


CHANGES IN TAX AND OTHER LAWS MAY ADVERSELY AFFECT UNITHOLDERS.

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  allowance,  may in the future be changed or  interpreted in a manner
that adversely affects us and our Unitholders.

In  particular,  generally  speaking,  the Tax Act provides  that a trust will
permanently  lose its "mutual  fund trust"  status  (which is essential to the
income trust  structure) if it is established or maintained  primarily for the
benefit of  non-residents  of Canada (which is generally  interpreted  to mean
that the majority of unitholders must not be non-residents of Canada),  unless
at all times  after  February  21,  1990,  "all or  substantially  all" of the
trust's property  consisted of property other than taxable  Canadian  property
(the "TCP  EXCEPTION").  Based on the most recent  information  obtained by us
through our transfer agent and financial  intermediaries,  in February 2006 an
estimated  60%  of our  issued  and  outstanding  Trust  Units  were  held  by
non-residents  of Canada  (as  defined  in the Tax Act) at that  time.  We are
currently able to take advantage of the TCP  Exception,  and as a result,  the
Trust  Indenture does not currently have a specific limit on the percentage of
Trust Units that may be owned by non-residents.

On March 23, 2004 the Canadian federal  government  announced proposed changes
to the Tax Act which would have effectively eliminated, over a period of time,
the TCP Exception  currently relied on by us to maintain our mutual fund trust
status,  and, if implemented,  would require us to comply with the requirement
that it "not be  maintained  primarily for the benefit of  non-residents".  In
response to submissions from and discussions with  stakeholders,  the Canadian
federal government  suspended the implementation of those proposed amendments.
The  Canadian  Minister of Finance  indicated in the February 23, 2005 federal
budget  that  further  consultations  would be pursued  with  stakeholders  on
taxation issues related to income trusts and other flow-through  entities.  On
September 8, 2005,  the Canadian  Department of Finance  released a discussion
paper on these matters and invited  interested  parties to make submissions to
the Department of Finance.  On November 23, 2005, the former Canadian Minister
of Finance  issued a news release  announcing  that no change would be made to
the tax  treatment  of  income  trusts  in Canada  and  calling  an end to the
consultation process initiated in September 2005.

Notwithstanding  the above,  there is no assurance that the TCP Exception will
continue to be available to the Trust or that the Canadian federal  government
will not  introduce  new changes or proposals to tax  regulations  directed at
non-resident  ownership which,  given our level  non-resident  ownership,  may
result  in  us  losing  our  mutual  fund  trust  status  or  could  otherwise
detrimentally  affect us and the market price of the Trust Units. We intend to
continue to take the necessary measures in order to ensure that we continue to
qualify as a mutual  fund trust  under the Tax Act.  There  would be  material
adverse  consequences  if we lost our  status  as a mutual  fund  trust  under
Canadian  tax laws.  See  "Changes  in  Legislation  -  Material  Adverse  Tax
Consequences to Loss of Mutual Fund Trust Status".

However, we may not be able to take steps necessary to ensure that we maintain
our  mutual  fund  trust  status.  Even if we are  successful  in taking  such
measures,  these measures could be adverse to certain  holders of Trust Units,
particularly  "non-residents" of Canada (as defined in the Tax Act). There can
be no assurance that such  circumstances  would not  detrimentally  affect the
market price of the Trust Units.

Additionally, legislation may be implemented to limit the investment in income
funds and royalty trusts by certain investors or to change the manner in which
these entities are taxed. Tax authorities  having  jurisdiction over us or our
Unitholders  may disagree with how we calculate our income for tax purposes or
could change administrative practices to our detriment or the detriment of our
Unitholders.

CHANGES IN LEGISLATION - MATERIAL  ADVERSE TAX  CONSEQUENCES TO LOSS OF MUTUAL
FUND TRUST STATUS

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


                                      64


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.

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


                                      65


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 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


                                      66


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  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.  Notwithstanding the provisions of
the Trust Indenture and the fact that Alberta (our governing jurisdiction) has
adopted legislation purporting to limit trust unitholder liability, because of
uncertainties in the law relating to investment trusts, there is a risk that a
Unitholder  could be held  personally  liable for  obligations of the Trust in
respect of  contracts  or  undertakings  which the Trust  enters  into and for
certain  liabilities  arising otherwise than out of 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.

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.

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.

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.

CHANGES IN ACCOUNTING STANDARDS

During 2005 there were several  changes to financial  reporting  requirements.
The changes impacting us are noted below.

     FINANCIAL INSTRUMENTS - PRESENTATION AND DISCLOSURE

Effective  January  1,  2005,  the  Fund  retroactively  adopted  the  revised
accounting  standard  Section 3860 "Financial  Instruments - Presentation  and
Disclosure" as issued by the CICA. The revised  standard  applies to financial
instruments  that may be  settled  at the  issuer's  option in cash or its own
equity instruments and impacts our prior accounting for convertible debentures
and the  performance  incentive fee. We previously  classified the issuance of
convertible  debentures  and the  performance  fee obligation as components of
equity on the basis that the obligations could be settled with the issuance of
Trust Units.  Interest  expense and issuance  costs related to the  debentures
were  charged to  accumulated  income as a component  of equity.  Based on the
revised standard,  a financial  instrument is presented based on the substance
of the  contractual  arrangement  regardless of the means of settlement.  This
results  in  the  reclassification  of  convertible  debentures  to  long-term
liabilities and the performance fee to current  liabilities.  Additionally,  a
financial  instrument with an embedded  conversion  feature must be segregated
between  liabilities and equity based on the relative fair market value of the
liability  and equity  portions.  Therefore,  the  debenture  liabilities  are
presented at less than their  eventual  maturity  values.  The  liability  and
equity  components are further reduced for issuance costs initially  incurred.
The  discount of the  liability  component  as  compared to maturity  value is
accreted by the  "effective  interest"  method  over the  debenture  term.  As
debentures  are  converted  to Trust  Units,  an  appropriate  portion  of the
liability and equity  components  are  transferred  to  Unitholders'  capital.
Interest and accretion expense on the convertible  debentures are shown on the
Consolidated Statements of Income.

     EXCHANGEABLE SHARES

In  March  2005,  the  CICA's  Emerging  Issues   Committee   amended  EIC-151
"Exchangeable  Securities  Issued by Subsidiaries  of Income Trusts".  The EIC
specifies the required criteria to present  exchangeable shares as a component
of Unitholders' equity. Exchangeable shares that do not meet both criteria are
classified as either debt or non-controlling  interest depending on the nature
of the  instrument.  Prior to the amendment,  Exchangeable  Shares of AOG were
shown as a component of Unitholders' equity.  However, the Exchangeable Shares
do not meet the requirements of the amended standard given that the shares are
transferable, although not publicly traded. Therefore, Exchangeable Shares are
now classified as non-controlling  interest,  outside of Unitholders'  equity.
The Exchangeable Shares and Trust Units are considered economically equivalent
since the exchange ratio is increased on each date that a distribution is paid
on the Trust Units and all shares must be exchanged  for either Trust Units or
cash,  based  on the  current  market  price of the  Trust  Units.  Since  the
Exchangeable  Shares  are  required  to be  exchanged,  there is no  permanent
non-controlling  interest. As a consequence of presenting  Exchangeable Shares
as non-controlling interest, a corresponding expense is recorded that reflects
the earnings attributable to the non-controlling  interest.  When Exchangeable
Shares are  converted to Trust Units,  the carrying  value of  non-controlling
interest on the balance sheet is  reclassified  to  Unitholders'  capital.  We
retroactively  implemented the revised standard but there was no income impact
on periods prior to 2005 given that the Exchangeable Shares were issued at the
end of 2004.

     FINANCIAL INSTRUMENTS -- RECOGNITION AND MEASUREMENT

In April  2005,  a series of new  accounting  standards  were  released  which
established   guidance  for  the  recognition  and  measurement  of  financial
instruments.  These new standards include Section 1530 "Comprehensive Income",
Section 3855  "Financial  Instruments --  Recognition  and  Measurement",  and
Section 3865 "Hedges", in each case issued by the CICA. The new standards also
resulted  in  a  number  of  significant  consequential  amendments  to  other
accounting  standards to accommodate the new sections.  The standards  require
all  applicable  financial  instruments  to be classified  into one of several
categories  including:  financial  assets and financial  liabilities  held for
trading,     held-to-maturity    investments,     loans    and    receivables,
available-for-sale  financial  assets,  or other  financial  liabilities.  The
financial  instruments  are then  included  on an issuer's  balance  sheet and
measured  at  fair  value,   cost  or  amortized   value,   depending  on  the
classification.  Subsequent measurement and recognition of changes in value of
the financial  instruments also depends on the initial  classification.  These
standards are effective for interim and annual financial statements for fiscal
years  beginning  on  or  after  October  1,  2006  and  must  be  implemented
simultaneously.  We have not yet assessed  the full  impact,  if any, of these
standards on the consolidated  financial  statements.  However,  we anticipate
adoption of the new standards on January 1, 2007.

RISKS PARTICULAR TO UNITED STATES AND OTHER NON-RESIDENT UNITHOLDERS

In addition to the risk factors set forth above,  the  following  risk factors
are particular to unitholders who are not residents of Canada.

UNITED STATES AND OTHER NON-RESIDENT  UNITHOLDERS MAY BE SUBJECT TO ADDITIONAL
TAXATION.

The Tax Act and the tax treaties between Canada and other countries may impose
additional  withholding  or other  taxes on the  cash  distributions  or other
property paid by us to Unitholders who are not residents of Canada,  and these
taxes may change from time to time. For instance, since January 1, 2005, a 15%
withholding tax is applied to return of capital portion of distributions  made
to non-resident unitholders.

THE ABILITY OF UNITED STATES AND OTHER NON-RESIDENT  UNITHOLDERS  INVESTORS TO
ENFORCE CIVIL REMEDIES MAY BE LIMITED.

We are a trust organized under the laws of Alberta,  Canada, and our principal
place of business is in Canada.  All of the  directors and officers of AOG are
residents  of Canada and most of the experts who provide  services to us (such
as its auditors and some of its independent  reserve  engineers) are residents
of Canada, and all or a substantial portion of their assets and our assets are
located within Canada.  As a result,  it may be difficult for investors in the
United States or other non-Canadian  jurisdictions (a "FOREIGN  JURISDICTION")
to effect  service of  process  within  such  Foreign  Jurisdiction  upon such
directors,  officers and  representatives  of experts who are not residents of
the Foreign Jurisdiction or to enforce against them judgments of courts of the
applicable   Foreign   Jurisdiction  based  upon  civil  liability  under  the
securities laws of such Foreign Jurisdiction,  including United States federal
securities  laws or the securities laws of any state within the United States.
In particular, there is doubt as to the enforceability in Canada against us or
any of our  directors,  officers  or  representatives  of experts  who are not
residents  of the  United  States,  in  original  actions  or in  actions  for
enforcement of judgments of United States courts of  liabilities  based solely
upon the United States federal  securities  laws or the securities laws of any
state within the United States.

    DISCLOSURE PURSUANT TO THE REQUIREMENTS OF THE NEW YORK STOCK EXCHANGE

As a Canadian  issuer listed on the New York Stock  Exchange (the "NYSE"),  we
are not  required to comply with most of the NYSE rules and listing  standards
and  instead  may comply  with  domestic  requirements.  As a foreign  private
issuer,  we are only required to comply with three of the NYSE Rules:  1) have
an audit  committee  that  satisfies  the  requirements  of the United  States
Securities  Exchange Act of 1934; 2) the Chief Executive Officer must promptly
notify the NYSE in writing  after an executive  officer  becomes  aware of any
material non-compliance with the applicable NYSE Rules; and 3) provide a brief
description of any significant  differences  between our corporate  governance
practices and those followed by U.S.  companies listed under the NYSE. We have
reviewed the NYSE listing standards and confirm that our corporate  governance
practices do not differ significantly from such standards.

                            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
circular for the most recent annual meeting of shareholders  that involved the
election of directors.  Additional  financial  information  is provided in our
financial  statements  and  management's  discussion and analysis for the year
ended December 31, 2005.  Documents  affecting the rights of  securityholders,
along with additional information relating to Advantage, may be found on SEDAR

                            REPORT ON RESERVES DATA

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

2.   We have evaluated the Trust's  reserves data as at December 31, 2005. The
     reserves data consist of the following:

     (a)  (i)   proved and proved plus probable oil and gas reserves estimated
                as at December 31, 2005 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, 2005
                using constant prices and costs; and

          (ii)  the related estimated future net revenue.

3.   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).

4.   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.

5.   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, 2005, and identifies the respective  portions  thereof
     that we have  audited,  evaluated  and  reviewed  and  reported on to the
     Trust's board of directors:

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  judgments  regarding  future
     events, actual results will vary and the variations may be material.
