               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 or 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 a plan of
arrangement  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.  Effective June 23, 2006,  Advantage and Ketch  completed the  Arrangement
with the combined  entity  continuing  under the name  Advantage  Energy Income
Fund. See "GENERAL DEVELOPMENT OF THE BUSINESS".

Prior to completion of the Arrangement,  Advantage  Investment  Management Ltd.
("AIM")  acted as manager of the Trust and of AOG. As part of the  Arrangement,
Advantage  internalized  its external  management  structure and eliminated all
related  fees by  acquiring  all of the  outstanding  shares  of AIM for  total
consideration  initially valued at $39.1 million,  paid through the issuance of
1,933,208 Trust Units which have been placed in escrow and are releasable as to
one-third on each of the first three anniversaries of the Arrangement.

Effective   September  5,  2007,   Advantage  and  Sound  completed  the  Sound
Arrangement  whereby Advantage acquired all of the issued and outstanding trust
units of Sound and exchangeable  shares of SET for  consideration of either (i)
0.30 of a Unit;  or (ii)  $0.66 in cash and  0.2557 of a Unit,  for each  Sound
trust  unit or SET  exchangeable  share  held.  In  connection  with the  Sound
Arrangement, SET, AOG and various other subsidiaries of Advantage, AOG, SET and
Sound  amalgamated to form "Advantage Oil & Gas Ltd." See "GENERAL  DEVELOPMENT
OF THE BUSINESS".

Our head  office,  the head office of AOG and the  registered  office of AOG is
located at Suite 700, 400, 3 Avenue S.W., Calgary, Alberta T2P 4H2.

In accordance with the terms of the Trust Indenture, 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

as our auditors.


                      GENERAL DEVELOPMENT OF THE BUSINESS

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.


                                       8


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".  The
listing on the NYSE has  resulted in improved  liquidity  for all  Unitholders,
greater access to the U.S.  capital  markets,  and improved cost of capital for
future acquisitions.

2006

On March 8, 2006, AOG elected to exercise its redemption right to redeem all of
its outstanding  exchangeable  shares.  The redemption  price per  exchangeable
share was  satisfied  by  delivering  that  number of Trust  Units equal to the
exchange  ratio of  1.22138 in effect on May 9, 2006.  During  2006,  we issued
127,014 Trust Units for the remaining AOG exchangeable shares.

On June 23, 2006 we completed the merger of Advantage and Ketch under the terms
of the Arrangement.  The merger was  accomplished  through the exchange of each
trust unit of Ketch for 0.565 of a Trust Unit of Advantage and upon completion,
Advantage  Unitholders owned  approximately 65% of the combined trust and Ketch
unitholders owed approximately 35%.

On July 24,  2006 we  announced  that we  adopted a  Premium  Distribution(TM),
Distribution  Reinvestment  and Optional Trust Unit Purchase Plan (the "PLAN").
The Plan  commenced  with the monthly cash  distribution  payable on August 15,
2006  to  Unitholders  who  elected  to  participate  and  have  their  monthly
distribution  obligation settled through the issuance of additional Trust Units
at 95% of the average market price (as defined in the Plan).

On August 1, 2006 we issued 7,500,000 Trust Units under a short-form prospectus
offering at $17.30 per Trust Unit.  An  additional  1,125,000  Trust Units were
issued on August 4, 2006 at $17.30  per Trust  Unit upon full  exercise  of the
over-allotment  option  provided to the  underwriters.  The net proceeds of the
offering  of   approximately   $141.4  million  were  used  to  pay  down  bank
indebtedness   and  to   subsequently   fund  capital  and  general   corporate
expenditures.

2007

On January 19, 2007,  we  announced  that the cash  distribution  to be paid on
February  15,  2007 to  Unitholders  of record on  January  31,  2007  would be
adjusted  to $0.15 per Trust Unit from the then  current  distribution  rate of
$0.18 per Trust Unit and that the  reduction in the monthly  distribution  rate
arose as a result of recent  weakness in crude oil and natural gas prices which
have been driven by an abnormally mild winter heating season.

On January 19,  2007,  we also  announced  that the Board of  Directors  of AOG
approved our 2007 capital expenditure budget at between $120 and $145 million.

On  February  14,  2007 we issued  7,800,000  Trust  Units  under a  short-form
prospectus offering at $12.80 per Trust Unit. An additional 800,000 Trust Units
were  issued on March 7, 2007 at $12.80  per Trust  Unit upon  exercise  of the
over-allotment  option  provided to the  underwriters.  The net proceeds of the
offering  of   approximately   $104.1  million  were  used  to  pay  down  bank
indebtedness and to fund capital and general corporate expenditures.

On June 22, 2007,  new  legislation  was passed  pursuant to which,  commencing
January 1, 2011 (provided that we only experience "normal growth" and no "undue
expansion" before then) certain distributions will be subject to at trust-level
tax,  and will be  characterized  as dividends  to the  unitholders.  See "RISK
FACTORS - CHANGES IN LEGISLATION - SIFT TAX".

On July 9, 2007  Advantage and Sound jointly  announced  that their  respective
boards of directors had approved the Sound  Arrangement.  On September 5, 2007,
the Sound  Arrangement  was  approved  by the  holders of trust  units of Sound
("SOUND UNITS") and holders of exchangeable shares of SET ("SOUND  EXCHANGEABLE
SHARES") and Advantage  completed  the  acquisition  of all of the  outstanding
Sound Units and Sound Exchangeable  Shares.  Pursuant to the Sound Arrangement,
holders of Sound Units  received 0.30 of a Unit for each Sound Unit held or, at
the election of the holder of Sound Units ("SOUND UNITHOLDERS"),  $0.66 in cash
and 0.2557 of a Unit. In addition, all Sound Exchangeable Shares were exchanged
for  Units  or  Units  and  cash  at the  election  of  the  holders  of  Sound
Exchangeable  Shares on the same terms as those  offered  to Sound  Unitholders
based on the  exchange  ratio in  effect  at the  effective  date of the  Sound
Arrangement.  In total 16,977,184 Units and $21.4 million in cash was issued to
holders of Sound Units and Sound  Exchangeable  Shares. In addition,  Advantage
also assumed  approximately $108.0 million of bank indebtedness upon closing of
the Sound Arrangement. See "SIGNIFICANT ACQUISITIONS" below.


                                       9


On August 16, 2007, we announced  that Stephen Balog had been  appointed to the
Board of Directors of AOG.

We  negotiated  an increase to our credit  facilities  in September of 2007 and
currently have a $710 million credit  facility  agreement  consisting of a $690
million  extendible  revolving  loan facility and a $20 million  operating loan
facility.  The credit  facilities are secured by a $1 billion  floating  charge
demand debenture,  a general security  agreement and a subordination  agreement
covering all assets and cash flows.

On September 18, 2007, our former auditors KPMG LLP resigned as auditors of the
Trust and PricewaterhouseCoopers LLP were appointed the auditors of the Trust.

On December 14, 2007,  Advantage announced that in light of the recent strength
of the Canadian dollar  combined with the continuing  weakness in crude oil and
natural gas prices,  the Board of Directors of Advantage  felt it is prudent to
adjust the cash distribution  beginning with the month of December to $0.12 per
Unit from the current $0.15 per Unit.

On December  14,  2007,  we also  announced  that the Board of Directors of AOG
approved our 2008 capital expenditure budget at between $130 and $145 million.

RECENT DEVELOPMENTS

Advantage has completed  additional  hedging for 2008 and 2009 to (i) stabilize
cash flows and (ii) ensure that the Trust's  capital  program is  substantially
funded out of cash flow.  Approximately  53% (net of royalties) of  Advantage's
natural  gas is  hedged  for the 2008  calendar  year at a floor of  $7.52/mcf.
Advantage  also hedged 38% (net of royalties) of its 2008 crude oil  production
at an average price of $94.07/bbl.

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 2008 financial year.

SIGNIFICANT ACQUISITIONS

On September 5, 2007,  Advantage  completed the acquisition of all of the Sound
Units and Sound Exchangeable  Shares.  Pursuant to the Arrangement,  holders of
Sound  Units  received  0.30 of a Unit  for each  Sound  Unit  held or,  at the
election  of the Sound  Unitholders,  $0.66 in cash and  0.2557  of a Unit.  In
addition,  all Sound Exchangeable  Shares were exchanged for Units or Units and
cash at the election of the Sound Exchangeable Shareholder on the same terms as
those offered to Sound Unitholders based on the exchange ratio in effect at the
effective date of the Sound  Arrangement.  In total  16,977,184 Units and $21.4
million in cash was issued to  holders  of Sound  Units and Sound  Exchangeable
Shares.  In addition,  Advantage also assumed  approximately  $108.0 million of
bank indebtedness upon closing of the Sound Arrangement.

On completion of the Sound Arrangement,  Sound became an indirect  wholly-owned
subsidiary of AOG and as part of the Sound Arrangement, certain assets owned by
Sound and SET were  transferred  to Advantage  and AOG and SET was  amalgamated
with Sound  ExchangeCo Ltd, 1135703 Alberta Ltd. and AOG to form "Advantage Oil
& Gas Ltd."

Prior to completion of the Sound Arrangement, the Sound Units traded on the TSX
under  the  symbol  SND.UN  and the  debentures  issued  by Sound  (the  "SOUND
DEBENTURES") traded on the TSX under the symbols SND.DB and SND.DB.A. Following
completion  of the  Arrangement,  the Sound Units were delisted from trading on
the TSX and Advantage  assumed all of Sound's  covenants and  obligations  with
respect to the outstanding  Sound  Debentures.  The debentures now trade on the
TSX under the symbols  "AVN.DB.F" and  "AVN.DB.G" for the 8.75%  Debentures and
the 8.00% Debentures,  respectively. Advantage made an offer to purchase all of
the outstanding  8.75% Debentures and 8.00% Debentures at a price equal to 101%
of the principal amount plus any accrued and unpaid  interest.  Pursuant to the
offer,  $35,958,000  principal  amount of 8.75% Debentures and 8.00% Debentures
plus accrued and unpaid  interest were tendered in exchange for the issuance of
3,131,998 Trust Units,  and $19,214,000  principal  amount of 8.75%  Debentures
plus accrued and unpaid interest were tendered for cash. The Trust Units issued
and cash paid  represented  101% of the  tendered  8.75%  Debentures  and 8.00%
Debentures  principal  amount plus  accrued and unpaid  interest  for July 1 to
October 18, 2007.


                                      10


The Sound Arrangement had the effect of improving  Advantage's payout ratio and
provided  substantial  operating synergies for the combined trust. The combined
entity has a significant prospect inventory and an undeveloped land position of
approximately  686,000 net acres,  providing  significant growth opportunities,
complementary   winter/summer   drilling  programs,   a  reduction  in  general
administration  costs, and further control and synergies in the common combined
properties.  Unitholders benefited through the addition of Sound's tax pools of
approximately $394 million, a 30% increase, for combined tax pools in excess of
approximately $1.7 billion at December 31, 2007. The combined entity had a 2007
exit rate production of approximately 34,300 boe/d weighted 63% natural gas and
37% light oil and NGLs.  The  combined  entity also has a Proved plus  Probable
Reserve  Life Index of  approximately  12.1 years  using  average  2007  fourth
quarter production and December 31, 2007 proved plus probable reserves.

        without limitation, facilities of any kind and whether effected through

        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

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.


                                      11


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.

REORGANIZATIONS

Other  than the  Arrangement  and the  Sound  Arrangement,  there  have been no
material  reorganizations  of Advantage  or AOG and or any of our  subsidiaries
within the three most recently  completed  financial  years or proposed for the
current financial year.

ADDITIONAL INFORMATION RELATING TO RESERVES DATA

UNDEVELOPED RESERVES


Undeveloped reserves are attributed by Sproule in accordance with standards and
procedures  contained in the COGE  Handbook.  Proved  undeveloped  reserves are
those  reserves  that can be estimated  with a high degree of certainty and are
expected  to  be  recovered  from  known   accumulations  where  a  significant
expenditure  is  required  to  render  them  capable  of  production.  Probable
undeveloped  reserves are those  reserves that are less certain to be recovered
than proved reserves and are expected to be recovered from known  accumulations
where  a  significant  expenditure  is  required  to  render  them  capable  of
production.  Proved and probable  undeveloped  reserves  have been  assigned in
accordance  with  engineering  and  geological  practices  as defined  under NI
51-101. In general,  undeveloped  reserves are planned to be developed over the
next two years.

In some cases,  it will take longer than two years to develop  these  reserves.
There  are a number of  factors  that  could  result in  delayed  or  cancelled
development,  including the following: (i) changing economic conditions (due to
pricing,  operating  and  capital  expenditure  fluctuations);   (ii)  changing
technical   conditions   (including   production   anomalies,   such  as  water
breakthrough or accelerated  depletion);  (iii)  multi-zone  developments  (for
instance,  a prospective  formation completion may be delayed until the initial
completion is no longer economic);  (iv) a larger development  program may need
to be spread out


                                      17


over several years to optimize capital allocation and facility utilization; and
(v) surface access issues  (including  those  relating to land owners,  weather
conditions and regulatory approvals). For more information, see "Risk Factors".

The following tables set forth the proved undeveloped reserves and the probable
undeveloped  reserves,  each by product type, first attributed to us in each of
the following financial years.

Sproule has assigned 13.6 MMboe of proven  undeveloped  reserves in the Sproule
Report  under  forecast  prices  and  costs,  together  with  $177  million  of
associated undiscounted future capital expenditures. Proven undeveloped capital
spending in the first two  forecast  years of the Sproule  Report  accounts for
$142 million, or 80 percent,  of the total forecast.  These figures increase to
$176 million or 99 percent,  during the first five years of the Sproule Report.

Sproule  has  assigned  26.6 MMboe of  probable  undeveloped  reserves  and has
allocated  future   development   capital  of  $194  million  to  all  probable
undeveloped reserves with $193 million scheduled for the first five years.


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 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.

There can be no guarantee that funds will be available or that we will allocate
funding  to develop  all of the  reserves  attributed  in the  Sproule  Report.
Failure  to develop  those  reserves  would  have a  negative  impact on future
production  and  cash  flow and  could  result  in  negative  revisions  to our
reserves.

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 four
western Canadian provinces, with the majority of our properties concentrated in
Alberta and northeastern British Columbia and in southeast Saskatchewan.  These
properties  produce from a variety of various aged  geological  formations  and
reservoirs.  We operate over 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 27% of our production and 29% of
our reserves. A further 62% of production and 60% of reserves are natural gas.

Rates referenced in the following property  descriptions are as of December 31,
2007 unless  otherwise noted and reserves quoted are as reported in the Sproule
Report to December 31, 2007.

MARTIN CREEK, BLACK AND CONROY, BRITISH COLUMBIA

The Martin Creek property is located  approximately 100 kilometres northwest of
Fort St. John,  British Columbia.  The property is operated with an average 76%
overall  working  interest.  This property is in the winter drilling area which
requires all drilling,  completion  and tie in activities to occur  essentially
between  January  1 and the end of March  each  season.  In the  latest  winter
program beginning in January 2008, 10 wells averaging 95% working interest were
drilled in the Conroy area in the northern  part of the  property.  These wells
were successful in multiple zones including the Cretaceous Bluesky Formation as
well as  reservoirs  within the Triassic  Charlie Lake  Formation.  These zones
occur at moderate depths between 800 to 1,300 metres.  All 10 wells in the 2008
program  were  cased  with 9 of these  completed  and  tied in  along  with one
additional well from the 2007 program being tied in as well.  Total  production
prior  to this  winter's  drilling  program  from  the  greater  Martin  Creek,
including the Black - Conroy areas is  approximately  18 MMcf/d or 3,000 boe/d.
Additional

facilities,  pipeline and compression  options will be scoped in 2008 to handle
subsequent  anticipated  volumes  from  current and future  drilling  programs.
Advantage  constructed  a 26  kilometre  all  year  access  road  to our  major
compression  sites that will also allow us the flexibility to expand outside of
the winter  operating  season should we choose to bring on extra capacity which
resulted from the successful 2008 program.  This year's  drilling  results have
set up a similar 2009  drilling  program,  should we choose to execute on it at
that time.  In addition we own 60% to 100%  working  interest  ownership in key
facilities,  including five compressor  stations,  one gas plant with 24 MMcf/d
current  throughput  and over 290  kilometres  of  pipelines,  which gives us a
dominant infrastructure position in this portion of British Columbia.

Sproule  evaluated  our proved  reserves in the area and  assigned  37.6 bcf of
natural  gas and 752  Mbbls of crude  oil and NGLs.  In  addition,  22.4 bcf of
probable  natural gas  reserves  and 446 Mbbls of  probable  crude oil and NGLs
reserves have been assigned to this property.

STODDART (NORTH PINE), BRITISH COLUMBIA

The  Stoddart/North  Pine area lies just 8 kilometres  west of the Town of Fort
St. John in northeast  British  Columbia.  This area is within the agricultural
area  and is  accessible  year  round.  The  property  produces  from  multiple
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 operating 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. Recently this area of British
Columbia has become the focus of exploration and  development  interest for the
Triassic  Montney tight gas play which is being  explored on adjacent lands and
developed further along trend to the southeast at Dawson and Swan. Advantage is
evaluating the Montney gas resource potential on our lands which include 16,800
gross (11,800 net) acres of  undeveloped  land with rights to this interval and
we are planning for a possible new drilling  location or recompletion  later in
2008 to evaluate this resource.

Current production from the Stoddart area is 580 boe/d.

Sproule  evaluated  our proved  reserves in the area and  assigned  12.7 bcf of
natural gas and 762 Mbbls of crude oil and NGLs. In addition, 3 bcf of probable
natural gas reserves and 188 Mbbls of probable  crude oil and NGL reserves have
been assigned to this property.

ZAMA LAKE (SOUSA), ALBERTA

The Zama Lake property  lies 150  kilometres  south/southeast  of the Northwest
Territories/British  Columbia/Alberta  border  adjacent  to the Hay  Zama  Lake
Complex.  Productive  zones on this property are primarily oil and gas from the
Devonian Keg River,  Sulphur Point and Slave Point formations as well as gas in
the shallow Cretaceous Bluesky formation.  Regionally,  Keg River oil wells are
characterized by prolific carbonate reefs. Bluesky sandstone reservoirs tend to
provide lower deliverability,  but longer-life sweet-natural-gas production. In
February 2008 we drilled and successfully  completed two new Keg River reefs as
well as two shallow  Bluesky wells which were used to validate land leases.  We
own and operate a sour oil battery,  complete with treaters, tanks, oil-pumping
station  and  solution  gas   compression.   The  area  also  has  an  existing
gas-gathering system comprised of three owned and operated compressors complete
with a small refrigeration package,  dehydration,  and sales point.  Additional
capacity is available for further development of our lands.

Production from the Zama Lake/Sousa property is currently 1,100 boe/d.

The Sproule  Report  assigns 6.1 bcf of proven  natural gas  reserves and 1,195
Mbbls of proven NGL reserves to this property. In addition, 1.2 bcf of probable
natural gas reserves and 439 Mbbls of probable NGL reserves  have been assigned
to this property.

RAINBOW, ALBERTA

The Rainbow  property  lies 175  kilometres  south/southeast  of the  Northwest
Territories/British  Columbia/Alberta  border in northwest  Alberta.  The major
focus of production on this property is the  Cretaceous  Bluesky  formation,  a
shallow  sandstone  reservoir that covers an extensive area and offers low-risk
development.  No new  wells  were  drilled  in the  Bluesky  in 2007.


                                      20


With the  acquisition  of Sound,  we are  planning to optimize  facilities  and
reviewing  opportunities  for  improving  operations  prior to commencing a new
round of  drilling.  Upwards  of 50 infill  and/or  step out  locations  remain
available for development on this property.  In the winter season of 2006/2007,
field compression was added which will support long-term  sustained  production
volumes from the area.  Shallow  natural gas  production at Black is compressed
and  dehydrated  in an  owned  and  operated  facility  before  it  is  further
compressed and processed by a third-party  processor in the area. Other Rainbow
shallow natural gas production is compressed, refrigerated and dehydrated at an
owned and operated facility, then delivered to the TCPL System.

Current production from the Rainbow property is 1,000 boe/d.

The Sproule  Report  assigns 18.1 bcf of proven  natural gas reserves and 1,001
Mbbls of proven NGL reserves to this property. In addition, 3.4 bcf of probable
natural gas reserves and 807 Mbbls of probable NGL reserves  have been assigned
to this property.

FONTAS, ALBERTA

The Fontas  property is situated about 80 kilometres  south of the Rainbow Zama
oilfields and about 20 kilometres east of the British  Columbia/Alberta border.
Fontas is a natural gas property  which produces  primarily from  Mississippian
aged reservoirs in the Debolt, Shunda and Elkton Formations.  Gas is trapped as
these reservoirs are truncated beneath Cretaceous strata and is also trapped in
Cretaceous  channels  which  down cut into the  older  Mississippian  rock.  We
operate this winter only access property at a 65% working interest.  We operate
six strategically  located gas  processing/compression  facilities and over 200
kilometres  of gas  gathering  pipelines.  A  winter  road was  built  into the
property for well servicing and replenishment of perishables this winter but no
drilling program was undertaken.

Production from the Fontas property is currently 1,000 boe/d.

The  Sproule  Report  assigns 9.8 bcf of proven  natural  gas  reserves to this
property.  In  addition,  4.4 bcf of probable  natural gas  reserves  have been
assigned to this property.

SUNSET/VALLEYVIEW, ALBERTA

This area is located  approximately  100 kilometres  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  Triassic  "A"  Unit,  Sunset  "B",  and
Valleyview-Stump.  All  three  properties  produce  from the  Triassic  Montney
Formation,  which  in  this  area  is a  fine  grained  sandstone  conventional
reservoir.

SUNSET "A" - We have a 70% working interest and operate the Sunset Triassic "A"
Unit.  Production from the unit is predominantly  oil (32o API). The unit has a
forty year  production  history  with a very  stable  performance  and very low
decline,  indicating  that there is a lot more oil to be  recovered.  Advantage
commenced  infill  development of the pool in 2005 where two wells were drilled
to evaluate the viability of infill drilling.  These wells came on-stream at an
average rate of 75 bbls/d per well,  similar to that in the original  wells. An
additional  14 oil wells and an injector  were added in 2006  followed with the
addition of 5 oil wells and one water  injection well in 2007, all with similar
results.  Significant  upgrading to oil production and handling  facilities and
gathering systems has been ongoing throughout 2006 and 2007 to handle increased
oil production  and additional  water  injection for pressure  maintenance.  An
additional 22 locations have been identified with 5 wells budgeted for drilling
in 2008.

SUNSET "B" - Production from this Montney  reservoir is  predominantly  natural
gas although  there is a thin oil (32o API) column.  We have a 100% interest in
this pool. We own 100% of a sour gas processing plant and gathering system with
throughput  capacity  of 12  MMcf/d.  Associated  gas from  Sunset "A" and from
Valleyview is gathered and streams through this facility. No wells were drilled
in 2007 at Sunset "B".

VALLEYVIEW  - This  Montney  gas  pool  is  connected  to the  Sunset  "B"  gas
processing plant by a twelve kilometre pipeline.  We have a 93% average working
interest in the pool. There was no new drilling in this pool in 2007.

Currently  production from the  Sunset/Valleyview  area is approximately  1,400
boe/d.


                                      21


For the three  properties,  Sunset "A", Sunset "B" and Valleyview,  the Sproule
Report  assigns  12.7 bcf of proven  natural  gas  reserves  and 2,465 Mbbls of
proven crude oil and NGL reserves.  In addition,  17.1 bcf of probable  natural
gas reserves and 3,130 Mbbls of probable  crude oil and NGL reserves  have been
assigned to these properties.

GLACIER, ALBERTA

The  Glacier  property  lies along the east side of the border  between  Grande
Prairie,  Alberta and Dawson Creek, British Columbia.  The property consists of
83 sections with an average working interest of 93%. Current  production of 350
boe/d is  comprised  all of natural  gas out of various  producing  zones in 13
wells, which is at present processed at a third party facility. Although gas is
produced out of a variety of horizons in the Cretaceous  and Triassic  section,
the primary zone of interest is the rapidly emerging unconventional gas play in
the Triassic Montney formation tight gas siltstones.  We are in early stages of
drilling and scoping  this  resource on our lands and in the first three months
of 2008 Advantage drilled and completed various intervals within the Montney in
5 vertical wells (4.33 net) on the Glacier property.  These wells clearly frame
and  establish  the presence of reservoir in both the Upper  Montney shore face
portion  as  well as in the  Lower  Montney  shelf  /turbidite  portion  of the
formation  similar  to  adjacent  producing  fields  at Swan and  Dawson on the
British Columbia side of the border.  Drilling  locations are being secured for
drilling  horizontal  wells later in the year.  These  horizontal wells will be
split between  targeting both the upper and lower  prospective  portions of the
formation.  Multiple fracs in each  horizontal well will be deployed to achieve
maximum production rates.

Sproule  evaluated  our proved  reserves in the area and  assigned  16.8 bcf of
natural  gas and 151  Mbbls of crude  oil and NGLs.  In  addition,  36.4 bcf of
probable  natural gas  reserves  and 328 Mbbls of  probable  crude oil and NGLs
reserves have been assigned to this property.

WORSLEY, CECIL, CLEAR RIVER AND BOUNDARY LAKE, ALBERTA

These  properties  are  located  150  kilometres  north of the  City of  Grande
Prairie, Alberta in the Peace River Arch region.

WORSLEY - The Worsley property is complex geologically with numerous structural
and stratigraphic  reservoirs  ranging from 600 to 2,200 metres.  The principle
reservoirs are the Devonian,  Wabamun Formation,  Mississippian  Kiskatinaw and
Debolt  Formations  and  Cretaceous  Bluesky  and Gething  Formations.  We hold
varying interests in approximately 35 sections of land in this area,  generally
in excess of 50%.  We hold a 100%  working  interest  a 7 MMcf/d  capacity  gas
processing facility in Worsley.

CECIL - The Cecil area  consists  of varying  interests  in 16 sections of land
adjacent  to Worsley,  again with  multi-zone,  shallow and medium  drill depth
targets.  The principal  producing pool is the Charlie Lake JJ (Doig Formation)
pool. In 2007 our working  interest in this pool increased from 30% to 90% with
the  acquisition  of Sound.  We hold a 10% working  interest in a 50 MMcf/d gas
processing facility at Cecil.

BOUNDARY  LAKE - This property lies  immediately  west of the Worsley  property
just east of the British  Columbia/Alberta  border. The property consists of 15
sections of land  (variable but generally  greater than 40% working  interest.)
The  principle  asset at  Boundary  Lake is our 65.625%  working  interest in a
Halfway  Formation  gas pool  consisting  of two wells  which  have a  combined
extended  production  test  rate  in  excess  of 8  MMcf/d.  Extensive  pooling
discussions  with  partners,  ERCB  applications  and  a  purchase  of  partner
interests have delayed getting this pool coming on stream;  however this should
be on production by mid 2008 as most of the regulatory  and approval  processes
are near  complete.  One  additional  well is planned  for  drilling in 2008 on
expiring land.

CLEAR  RIVER - The  principle  asset on this  property  is our  interest in the
Triassic "CC" oil pool which is a Baldonnel  Formation  reservoir producing 33o
API crude oil at a depth of 1,200  metres.  Two wells  were  drilled in 2007 on
this property, one early in the year by Sound and a second late in 2007.

Current production from these 4 properties is 1,700 boe/d.

Sproule  evaluated our proved  reserves in these areas (Worsley,  Cecil,  Clear
River and  Boundary  Lake) and assigned 7.1 bcf of natural gas and 795 Mbbls of
crude oil and NGLs. In addition,  5.3 bcf of probable  natural gas reserves and
539 Mbbls of probable  crude oil and NGL reserves  have been  assigned to these
properties.


                                      22


NEVIS, ALBERTA

The Nevis  property  is situated 60  kilometres  east of Red Deer.  Nevis is an
operated  property  consisting  of  approximately  90  sections of land with an
average  working  interest  of 76%.  This  property  produces  natural gas from
numerous  shallow depth  horizons  (400 to 800 metres)  including the Horseshoe
Canyon,  Edmonton,  Belly River and Viking  formations.  Oil and natural gas is
produced from the slightly deeper  reservoirs (1,200 metres) of the Glauconite,
Ostacode and Ellerslie  formations within the Mannville Group. The main zone of
interest  however,  is an oil and gas reservoir which occurs at 1,600 metres of
depth in  Devonian  aged  carbonates  of the Big Valley  Member of the  Wabamun
Formation.  Because this reservoir is a low permeability  carbonate and as such
inflow in vertical wells is low, the pool is being  developed  with  horizontal
wells numbering 4 per section each with an average  horizontal  length of 1,200
metres.   Crude  oil  quality   ranges  between  35o  and  42o  API.  In  2007,
approximately  8  sections  of land with  Wabamun  rights  were  acquired  in a
property  acquisition.  An  additional  31  sections of land were added in 2007
through the acquisition of Sound which had a significant  land position synergy
with Advantage at Nevis. Drilling for the Wabamun in 2008 continues to focus on
new lands  primarily  located on the west side of the property.  Facilities and
compression  are  being  expanded  on the west  side of the Red  Deer  River to
accommodate  additional volumes established in 2007 drilling and anticipated in
2008. Oil on the property from all areas is collected at central facilities and
trucked to market.  Natural gas is gathered through company owned pipelines and
delivered to third party  midstream for final  processing and sale.  Currently,
the property is being  scoped for suitable  secondary  recovery  potential.  In
2007, 12 horizontal  wells were drilled into the Wabamun  formation and are all
currently  producing  with an average  first month  initial  production  of 122
boe/d.  The acquisition of Sound added 20 sections (55% net) which have shallow
Horseshoe Canyon coal bed methane ("CBM") potential.  We have budgeted 37 wells
(55% working  interest)  for CBM in 2008.  This program  commenced  drilling in
March. To accommodate shallow pressures  encountered with the CBM,  appropriate
upgrades to facilities and gathering  systems are being  implemented in 2008 as
well.

Nevis is Advantage's  largest producing  property with current  production from
all zones at Nevis over 4,600 boe/d.

The Sproule  Report  assigns 39.4 bcf of proven  natural gas reserves and 4,795
Mbbls of proven crude oil and NGL reserves to this property. In addition,  14.1
bcf of probable  natural gas reserves and 1,898 Mbbls of probable crude oil and
NGL reserves have been assigned to this property.

WILLESDEN GREEN (OPEN LAKE), ALBERTA

The Willesden Green property is located  approximately  35 kilometres  north of
the Town of Rocky Mountain  House. We operate and have in excess of 90% working
interest.  In 2007 we successfully  drilled and completed five 2,400 metre deep
wells (4.2 net) targeting two distinct plays, a Jurassic Rock Creek gas play on
the east side of the property  and a Cretaceous  Ellerslie/Ostracode/Glauconite
play on the north side of the property. In addition 3 wells were farmed out and
these were successfully  completed as well as Rock Creek gas wells. We retain a
15% overriding royalty in these latter three wells. In 2008, 3 additional wells
were  drilled  (100%  working  interest)  in the first  quarter  resulting in 2
Cretaceous oil wells and one additional Rock Creek gas well. Also, one well was
successfully recompleted in the Cretaceous as an oil well. For the remainder of
2008,  two additional  drilling  locations and 3 more  recompletions  have been
budgeted.

Current  production from all zones at Willesden Green is 1,100 boe/d,  with 600
additional  boe/d tested and completed  from the new 2008 wells drilled to date
and which will be coming on-stream in the second quarter of 2008.

Sproule  evaluated our proved reserves in the Willesden Green area and assigned
6.5 bcf of natural gas and 830 Mbbls of crude oil and NGLs.  Probable  reserves
in this area were  evaluated by Sproule at 2.7 bcf of natural gas and 350 Mbbls
of crude oil and NGLs.

WESTEROSE, ALBERTA

The Westerose  property is approximately  60 kilometres  southwest of Edmonton,
Alberta.  Westerose is an oil and gas  property  with  production  from various
Cretaceous  reservoirs but produces  principally  from several pools associated
with the  erosional  subcrop edge of the  Mississippian  Banff  Formation.  The
primary  pool is the  Banff  "C" Oil Unit in which we hold a 52%  interest  and
operate.  The reservoir in the Banff Formation is a dolomitized  carbonate that
is conducive to secondary  recovery  through  waterflooding.  The  reservoir is
currently under active waterflood  pressure  maintenance since 2003 and one new
injection  well was added to the  injection  scheme in 2007  along with two new
additional  oil  producers.  We also


                                      23


operate  five  compressor  stations  and 80  kilometres  of pipeline  gathering
facilities that are connected to the Rimbey gas plant.  One additional well and
one recompletion workover are budgeted for 2008.

Current production from all zones at the greater Westerose area,  including the
Banff "C" Oil Unit is 1,350 boe/d.

Sproule  evaluated  our proved  reserves in the Brazeau River area and assigned
8.9 bcf of natural gas and 2,095 Mbbls of crude oil and NGLs. Probable reserves
in this area were  evaluated  by Sproule  at 2.3 bcf of  natural  gas and 1,220
Mbbls of crude oil and NGLs.

BRAZEAU RIVER, ALBERTA

The Brazeau River property is located  approximately  50 kilometres 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. Major facility  interests
include a 25.7% working interest in the West Pembina Sour Gas Plant and a 31.6%
working interest in the Brazeau River Gas Plant.

Current production from the Brazeau area,  including the Nisku pinnacles is 725
boe/d.

Sproule  evaluated  our proved  reserves in the Brazeau River area and assigned
5.5 bcf of natural gas and 527 Mbbls of crude oil and NGLs.  Probable  reserves
in this area were  evaluated by Sproule at 2.8 bcf of natural gas and 273 Mbbls
of crude oil and NGLs.

LOOKOUT BUTTE, ALBERTA

The Lookout Butte property is located  approximately 90 kilometres southwest of
Lethbridge,  Alberta. Production occurs primarily from the Mississippian Rundle
Formation  where  natural  gas  has  been  trapped  in a  foothills  overthrust
structure in front of Waterton  Park.  We have a 100%  working  interest in the
Rundle gas production.  Production began in 1963 and production  decline is low
at  approximately  12% per year. A well drilled in 2004 in the southern portion
of the pool  indicates  the potential for  significant  undrained  reserves and
additional prospective locations targeting the Rundle carbonates.  The property
includes a 100% operated  working  interest  plant and associated gas gathering
system which dehydrates the gas before final processing at Shell's Waterton gas
plant. Two wells (50% working interest) have been recompleted in the Cretaceous
Dalhousie  Formation  which  occurs  at about  3,100  metres.  Both  wells  are
producing  between 100 and 150 boe/day.  A new well (50% working  interest) was
drilled at year end 2007 and it encountered  two overthrust  repeats of the pay
zone.  Completion of this well is still ongoing.  One  additional  well on this
play is budgeted for 2008.

Current  production  from Lookout  Butte in the  Mississippian  and  Cretaceous
intervals combined is 1,300 boe/d.

Sproule evaluated our proved reserves at Lookout Butte and assigned 30.6 bcf of
natural  gas and 1,592 Mbbls of crude oil and NGLs.  Probable  reserves in this
area were  evaluated  by Sproule  at 11.3 bcf of  natural  gas and 646 Mbbls of
crude oil and NGLs.

SHALLOW GAS PROPERTIES

A significant  portion of our  production  comes from shallow gas properties at
Medicine Hat, Bantry, and Shouldice. These projects are all located in southern
Alberta  and occur  between 500 and 1,200  metres 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.

MEDICINE HAT - The Medicine Hat property is located 20 kilometres  northeast of
the City of Medicine Hat in the heart of the south-eastern shallow gas area. We
have a 100% working  interest in 24 sections of land from where  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


                                      24


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.
From January 2002 to December 2005, 320 new wells were added. No new wells were
added in 2007.  Production  from this property is currently 9.5 MMcf/d or 1,550
boe/d.

Sproule  evaluated  our  reserves in the area and  assigned  43.1 bcf of proved
natural gas reserves and 10.6 bcf of probable reserves.  As such, this property
is our largest property on an assigned reserves basis.

BANTRY - This  property  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. 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  metres.  No new wells were added in 2007.  Natural  gas is gathered
into our operated  compression and dehydration  facilities.  Current production
from this area is 650 boe/d.

The Sproule  Report assigns 8.6 bcf of proven natural gas reserves and 33 Mbbls
of proven NGL  reserves  to this  property.  In  addition,  3.9 bcf of probable
natural gas reserves and 15 Mbbls of probable NGL reserves  have been  assigned
to this property.

SHOULDICE - The Shouldice area of southern Alberta is located  approximately 50
kilometres  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. No new wells were added in 2007. Both natural
gas and crude oil are produced and gathered  through our  facilities of varying
working interests. Current natural gas production of 420 boe/d is produced on a
co-mingled basis from the Medicine Hat Formation sands with various Belly River
Formation sands from approximately 90 wells.

The Sproule  Report assigns 7.3 bcf of proven natural gas reserves and 67 Mbbls
of proven crude oil and NGLs to this property.  In addition,  2 bcf of probable
natural gas reserves and 34 Mbbls of probable  crude oil and NGL reserves  have
been assigned to this property.

SOUTHEAST SASKATCHEWAN

This area  consists of a host of  individual  properties  within the  Williston
Sedimentary  Basin in the southeast corner of  Saskatchewan.  Production at the
major properties  comes  principally from the Ordovician Red River Formation at
Midale, Hardy and Froude,  Devonian Winnipegosis Formation at Steelman and from
Mississippian  Midale/Frobisher  Formations  at Steelman,  Weyburn and Workman,
McCoun and Crystal Hills. In 2007, we drilled 4.7 net wells. These included one
(0.6  net)  horizontal  at  Talmage  for  Ordovician,  Red  River Oil and 2 net
vertical  Frobisher  Oil wells at Pinto.  The  remaining  wells were drilled at
Elswick,  Queensdale and Crystal Hills.  In addition  Advantage  farmed out two
significant  blocks of land to two industry partners in the Midale/Froude  area
which have resulted in 10 Bakken horizontal wells with a 10% overriding royalty
and an  additional  two  additional  horizontals  with a 5 to 12% sliding scale
overriding  royalty. We have an additional 6 wells budgeted spread across these
properties in 2008.

Combined   production  from  all  the  properties  in  southeast   Saskatchewan
(excluding the Wapella area) is 1,755 boe/d.

Sproule  evaluated our proved reserves in southeast  Saskatchewan  and assigned
832  Mmcf of  natural  gas and  5,513  Mbbls of crude  oil and  NGLs.  Probable
reserves in this area were  evaluated by Sproule at 353 Mmcf of natural gas and
3,471 Mbbls of crude oil and NGLs.

WAPELLA/RED JACKET, SASKATCHEWAN

Our Wapella property is located in southeast Saskatchewan,  200 kilometres east
of Regina and  produces  medium-gravity  (25(0)  API) oil from  Cretaceous  and
Jurassic-aged  sandstone reservoirs.  This property was acquired in 2007 in the
Sound  acquisition.  It is  characterized  by its relatively  high reserve life
index, high working interest and substantial  undeveloped  acreage.  There is a
significant inventory of drilling locations. The pool is being developed with a
staged waterflood  program to enhance reserves and  productivity.  Future plans
call for continued delineation and development of the pool as well as expansion
of the  waterflood  scheme.  There are two drilling  locations  and a number of
recompletions budgeted on this property in 2008.


                                      25


Production from the Wapella area is currently 725 boe/d.

Sproule evaluated our proved reserves in Wapella/Red  Jacket and assigned 2,774
Mbbls of crude oil. Probable reserves in this area were evaluated by Sproule at
1,123 Mbbls of crude oil.

HEAVY OIL PROPERTIES (WESTERN SASKATCHEWAN - LLOYDMINSTER AREA)

The  majority of the east  Lloydminster  (Lashburn  and West Hazel) and Eyehill
properties lie on the Saskatchewan side of the  Saskatchewan/Alberta  border in
the  heart of the  Lloydminster  heavy oil  producing  area.  These  properties
produce  primarily from the Cretaceous  Sparky Formation and also from the Rex,
Cummings and Dina  Formations.  Crude gravities are all less than 19(0) API but
are  conventionally  produced  with some  pools  under  active  water  flood as
pressure  maintenance  schemes.  These  properties  were added to our portfolio
through the Sound Arrangement.

Currently production from these heavy oil properties is 475 boe/d.

Sproule  evaluated our proved  reserves in the Heavy Oil  Properties of western
Saskatchewan and assigned 88 Mmcf of natural gas and 902 Mbbls of crude oil and
NGLs.  Probable  reserves in this area were  evaluated by Sproule at 43 Mmcf of
natural gas and 2,666 Mbbls of crude oil and NGLs.

We expect that rights to explore,  develop and exploit 164,577 net acres of our
undeveloped   land  holdings  will  expire  by  December  31,  2008.  The  land
expirations do not consider our 2008 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.

We have  implemented a hedging  policy to use costless  collars and fixed price
swaps to hedge up to 60% of our gross  production for a maximum period of 1 1/2
years.  These  hedging  activities  could expose us to losses or gains.  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.

Overall,  approximately 53% of our gas is now hedged for the 2008 calendar year
at a floor  of  $7.52/mcf.  For the  first  quarter  of 2008,  we have  secured
approximately  22% of our net gas  production  at an $8.85/mcf  floor.  For the
first quarter of 2009, approximately 60% of our net gas production is hedged at
a floor of  $7.87/mcf.  We have also hedged  approximately  38% of our 2008 net
crude  production  at an average  floor price of  Cdn$94.07/bbl  and 32% of our
first quarter 2009 production at Cdn$95.84/bbl.

         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  initially  based upon  Sproule's  methodology,  which  details the cost of
abandonment  for the  major  properties  that we hold.  Our  initial  estimated
expenditures are then further adjusted for non-producing  wells,  pipelines and


                                      27


facilities,  and surface  reclamation  costs.  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 5,425
(gross)  producing and  non-producing  wells.  Costs to abandon and reclaim the
producing wells totals $20.3 million ($97.0 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,  and surface
reclamation costs was estimated to be $22.0 million ($146.9 million  discounted
at 10%),  and was not  deducted  in  estimating  future net  revenue.  Facility
reclamation costs are generally  scheduled to be incurred in the year following
the end of the reserve life of our  associated  reserves  under the  assumption
that  decommissioning of plant/facilities  are mobile assets with a long useful
life.

Abandonment and reclamation costs  undiscounted and included in the estimate of
future net  revenue  for the next three  years are $0.8  million in 2008,  $1.3
million in 2009 and $1.5 million in 2010.

TAX HORIZON

In 2007, we did not pay any income related taxes.

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  prior  to 2011  and it is our
intent to continue with the current  arrangement.  For the 2007  distributions,
100% were taxable to Canadian and U.S. Unitholders.

The Trust does not expect to pay income  taxes  until the earlier of January 1,
2011 or if and when it ceases  to be a trust.  New  legislation  passed in June
2007 will  impose a tax on  distributions  from  entities,  such as the  Trust,
beginning  generally on January 1, 2011.  Commencing in January 2011  (provided
that the Trust experiences only "normal growth" and no "undue expansion" before
then) the Trust will be liable for tax at the federal "net corporate income tax
rate" combined with the "provincial  SIFT tax factor"  (effectively the federal
general corporate tax rate plus 13% on account of provincial  corporate tax) on
all income payable to  Unitholders,  which the Trust will not be able to deduct
in computing its taxable income.

Subject to, among other things,  the  availability of drilling rigs and weather
that permits  access to drill sites,  in 2008,  we plan to drill,  complete and
tie-in 88 net wells and recomplete an additional 14 net wells.

We estimate  capital  expenditures  of between $125 million and $145 million in
2008 to execute our capital  programs.  The primary  components of our programs
are  described  under the  heading  "Other  Oil and Gas  information  - Oil and
Natural Gas Properties".

Notes:

(1)   Before deduction of royalties.
(2)   Production prices are net of costs to transport the product to market.
(3)   This figure includes all field operating expenses.
(4)   We do not record operating expenses on a commodity basis.  Information in
      respect of operating  expenses for crude oil and NGLs ($/bbl) and natural
      gas ($/Mcf) has been determined by allocating 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.
(5)   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 (4) above.

      Units.

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 &
      Petroleum;

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

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

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


                                      31


      (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:

      (e)   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;

      (f)   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;

      (g)   dry hole contributions and bottom hole contributions;

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

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

      "GROSS" means:

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

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

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

      "NET" means:

      (m)   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;

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

      (o)   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


                                      32


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.

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% probability that the quantities  actually  recovered
            will equal or exceed the estimated proved reserves; and

      (b)   at least a 50% 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 11% of our natural
gas


                                      33


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.

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 2008 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.

HEALTH, SAFETY AND ENVIRONMENTAL

AOG  is  committed  to  a  comprehensive  and  effective  health,   safety  and
environmental   program  that  meets  or  exceeds   regulatory   and  corporate
requirements.

Management,  employees and all  contractors are responsible and accountable for
the overall  health,  safety and  environmental  program.  AOG will  operate in
compliance  with all  applicable  regulations  and will  ensure  all  staff and
contractors  employ sound  practices to protect the  environment  and to ensure
employee and public health and safety.

We will maintain a safe and environmentally  responsible work place and provide
training,  equipment  and  procedures  to all  individuals  in  adhering to our
policies.  We will also  solicit  and take into  consideration  input  from our
neighbors,  communities and other  stakeholders in regard to protecting  people
and the environment.

AOG  participates in the  Environment,  Health and Safety  Stewardship  Program
developed by the Canadian  Association  of Petroleum  Producers.  Participation
requires  commitment to continuous  improvement in the environment,  health and
safety management  practices including sound planning and implementation,  open
communication and measured performance against our peers.

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, 2007, we employed 172 full-time employees,  139 of which are
located in the head  office and 33 of which are  located in the field.  We also
employed 27 consultants in the head office.

         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, 2007,  138,269,374 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  three  classes,  as  follows:  (i)
"ordinary  trust  units",  which  are  entitled  to  the  rights,   subject  to
limitations,  restrictions  and conditions set out in the Trust  Indenture,  as
summarized  herein;  (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;  and (iii)
"special trust units", which shall be entitled to the rights and subject to the
limitations,  restrictions  and conditions set out in the Trust  Indenture,  as
summarized  herein. As at the date hereof there are no special voting units and
no special  trust  units  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
(including  ordinary trust units and special 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.  Each special
trust unit  entitles  the holder or holders  thereof to one-half of one vote at
any meeting of the Unitholders and each ordinary trust unit entitles the holder
or holders thereof to one vote at any meeting of the Unitholders.

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 ability of the AOG Board of Directors to effect long term growth in
the value of the Trust.  The market  price of the Trust Units will be sensitive
to a variety of market  conditions  including,  but not  limited  to,  interest
rates,  commodity prices and our ability to acquire additional assets.  Changes
in market conditions may adversely affect the trading price of the Trust Units.

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

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

The after-tax  return from an investment in Trust Units to Unitholders  subject
to Canadian  income tax can be made up of both a return on capital and a return
of capital. That composition may change over time, thus affecting an investor's
after-tax  return.  Returns on capital will  generally  continue to be taxed as
ordinary income in the hands of a Unitholder until


                                      35


January 2011  (provided we do not exceed  "normal  growth" or experience  undue
expansion),  and will be treated  as  dividends  after  such  time.  Returns of
capital are generally  tax-deferred  (and reduce the Unitholder's  cost base in
the Trust Unit for tax purposes). Legislation affecting the tax treatment of an
investment  in Trust Units can change at any time.  See "RISK FACTORS - CHANGES
IN LEGISLATION".

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.

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.


                                      36


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 is 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 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


                                      37


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

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

MEETINGS OF UNITHOLDERS

The Trust  Indenture  provides that meetings of Unitholders  must be called and
held for,  among other  matters,  the election or removal of the  Trustee,  the
appointment or removal of our auditors, the approval of amendments to the Trust
Indenture  (except  as  described  under  "ADDITIONAL   INFORMATION  RESPECTING
ADVANTAGE ENERGY INCOME FUND - AMENDMENTS TO THE TRUST INDENTURE"), the sale of
our assets in their entirety or  substantially in their entirety (other than as
part of an  internal  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 2/3% 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 June 3,
2008.

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.


                                      38


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 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

AOG has generally  been  delegated our  significant  management  decisions.  In
particular, pursuant to the Administration Agreement, the Trustee has delegated

                  certification thereof; and

            (iii) all  matters  concerning  the  entering  into,  terms of, and

      (m)   providing  or causing to be provided  to the  Trustee any  services

            of the Trust Fund;

      (n)   providing advice and, at the request and under the direction of the

      (v)   doing all such things  regarding the use of commodity  price swaps,
            hedges or other such  instruments  or  agreements  on behalf of the
            Trust in  respect  of  commodity  prices  or rates of  exchange  of
            currencies or interest  rates,  the purpose of which is to mitigate
            or eliminate exposure to the fluctuations and prices of commodities
            or rates of exchange of one currency for another or interest rates.

For  more  information  as to the  AOG  Board  of  Directors,  see  "ADDITIONAL
INFORMATION RESPECTING ADVANTAGE OIL & GAS LTD. - MANAGEMENT OF AOG".

LIABILITY OF THE TRUSTEE

The Trustee, its directors, officers, employees,  shareholders and agents shall
not be liable to any  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 AOG or any other  appropriately  qualified person,  any
reliance upon any such evaluation,  any action or failure to act of the 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 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


                                      40


directors,  officers,  employees,  shareholders  or agents.  If the Trustee has
retained an  appropriate  expert,  adviser or legal counsel with respect to any
matter  connected  with its duties  under the Trust  Indenture  or any material
contract,  the  Trustee  may act or refuse to act based upon the advice of such
expert,  adviser or legal counsel,  and the Trustee shall not be liable for and
shall be fully protected from any loss or liability occasioned by any action or
refusal  to act based  upon the  advice of any such  expert,  adviser  or legal
counsel.  In the exercise of the powers,  authorities  or discretion  conferred
upon the  Trustee  under  the  Trust  Indenture,  the  Trustee  is and shall be
conclusively  deemed  to be acting as  Trustee  of the  assets of the Trust and
shall not be  subject to any  personal  liability  for any debts,  liabilities,
obligations,  claims, demands, judgments, costs, charges or expenses against or
with 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

The Trust  Indenture may be amended or altered,  from time to time, by at least
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
      (including  the Tax Act),  regulations,  requirements  or policies of any
      governmental or other authority having  jurisdiction  over the Trustee or
      over the Trust;

2.    ensuring  that we  will  satisfy  the  provisions  of  each  of  Sections
      108(2)(a)  and  132(6) of the Tax Act,  as from time to time  amended  or
      replaced;

3.    which, in the opinion of the Trustee,  provide additional  protection for
      or benefit to the Unitholders;

4.    to remove any  conflicts  or  inconsistencies  in the Trust  Indenture or
      making  corrections,  including the  correction or  rectification  of any
      ambiguities,  defective provisions,  errors, mistakes or omissions, which
      are,  in the  opinion of the  Trustee,  necessary  or  desirable  and not
      prejudicial to the Unitholders;

5.    which,  in the opinion of the  Trustee,  are  necessary or desirable as a
      result of changes in taxation laws; and

6.    removing or curing  inconsistencies  between the Trust  Indenture and the
      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.

In  December  2007,  the  Trust  Indenture  was  amended  to allow the Trust to
participate in the DRS. Effective January 1, 2008, all issuers whose securities
are listed on the New York Stock  Exchange  are  required  to ensure that their
listed  securities  are  eligible  for  participation  in the DRS. DRS eligible
issuers  must  provide an investor  with the  ability to have their  securities
registered in the  investors'  name directly on the issuer's books (through its
transfer agent) or through the investors' brokerage dealer, thereby eliminating
the need for physical  certificates to evidence  ownership of securities.  As a
result of the implementation of the need to be DRS eligible, certain amendments
were required to be made to the Trust Indenture of the Trust.

TERM OF THE TRUST AND SALE OF SUBSTANTIALLY ALL ASSETS

The Trust has been established for a term ending December 31, 2095. Pursuant 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 2/3% of the votes cast at a meeting
of the Unitholders.


                                      41


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

materially the control of the Trust or AOG has, within the last ten years prior
to the date of this document, been a director, chief executive officer or chief
financial  officer of any issuer (including AOG) that, (i) while the person was
acting in the capacity as director,  chief executive officer or chief financial
officer,  was the  subject of a cease  trade or similar  order or an order that
denied the company access to any exemption under securities  legislation,  that
was in effect for a period of more than thirty (30)  consecutive  days; or (ii)
was subject to an order that resulted, after the director, executive officer or
securityholder holding a sufficient number of securities of the Trust or AOG to
affect  materially  the  control of the Trust or AOG  ceased to be a  director,
chief executive  officer or chief financial officer of an issuer, in the issuer
being the subject of a cease trade or similar order or an order that denied the
relevant issuer access to any exemption  under  securities  legislation,  for a
period of more than thirty (30) consecutive  days, which resulted from an event
that  occurred  while that  person was acting as a  director,  chief  executive
officer or chief financial officer if the issuer.

No current director or officer or securityholder holding a sufficient number of
securities of the Trust or AOG to affect materially the control of the Trust or
AOG has,  within the last ten years prior to the date of this document,  been a
director or executive  officer of any company  (including AOG) that, while such
person was acting in that capacity,  or within a year of that person ceasing to
act in that capacity,  became  bankrupt,  made a proposal under any legislation
relating  to  bankruptcy  or  insolvency  or was subject to or  instituted  any
proceedings,  arrangement  for  compromise  with  creditors  or had a receiver,
receiver manager or trustee appointed to hold its assets.

In  addition,  no  current  director  or officer  or  securityholder  holding a
sufficient  number of securities of the Trust or AOG to affect  materially  the
control of the Trust or AOG has, within the last ten years prior to the date of
this document,  become bankrupt, made a proposal under any legislation relating

regulatory  authority;  or (ii) any other  penalties or sanctions  imposed by a
court or  regulatory  body that  would  likely  be  considered  important  to a
reasonable investor in making an investment decision.

CONFLICTS OF INTEREST

The  directors  and officers of AOG may,  from time to time, be involved in the
business and operations of other  issuers,  in which case a conflict may arise.
The ABCA provides that in the event 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  interests  arise,  such  conflicts  will be
resolved in accordance with the provisions of the ABCA.

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. Advantage is the sole holder
of the issued and outstanding  Common Shares.  There are no non-voting  shares,
preferred shares or exchangeable  shares issued and  outstanding.  Advantage 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 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  rights,
privileges,  restrictions  and conditions  attaching to any instruments  having
priority over the Common Shares.

NON-VOTING SHARES

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

PREFERRED SHARES

The preferred  shares may be issued,  from time to time, in one or more series,
each series  consisting of such number of preferred shares as determined by the
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.

NOTES

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

PAYMENT UPON MATURITY

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

RANKING

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

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

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 99% 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  99% 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 acquire or dispose of any properties  that will cost or result
in proceeds in excess of $5 million,  approval of the AOG Board of Directors is
required to approve such acquisition or disposition, respectively.

                              ESCROWED SECURITIES

As part of the Arrangement, shareholders of AIM received Trust Units in payment
for the sale of their  AIM  shares to the  Trust.  All such  shareholders  were
required to enter into an escrow agreement (the "ESCROW  AGREEMENT")  providing
for the release of Trust Units as to one-third on each  anniversary date of the
Arrangement for three years. All distributions  paid on the Trust Units held in
escrow  are  made  directly  to  the  holders  of  the  escrowed  Trust  Units,
notwithstanding that their Trust Units are in escrow.

All Trust Units will be released from escrow if a Change in Control (as defined
in the Escrow  Agreement)  occurs.  All Trust  Units being held in escrow for a
particular  shareholder will be released upon that shareholder ceasing to be an
employee  for any reason  other than  termination  for just cause or  voluntary
departure or resignation.

The Board may consent to the transfer  within escrow or the release from escrow
of Trust Units in such  circumstances  and on such terms and  conditions  as it
shall determine in its sole discretion.

The Trust Units subject to escrow at December 31, 2007 are as follows:

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 PricewaterhouseCoopers
LLP as set forth in item 15 of the Audit Committee charter, which is reproduced
below under the heading  "AUDIT  COMMITTEE  CHARTER".  The Audit  Committee has
approved the  provision of a specified  list of audit and  permitted  non-audit
services  that the audit  committee  believes  to be  typical,  reoccurring  or
otherwise  likely to be  provided  by  PricewaterhouseCoopers  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
of AOG in fulfilling its  responsibilities by reviewing:  the financial reports
and other financial  information provided by 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;


                                      56


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 the  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, or
the Trust and all of whom are  "independent"  (as such term is  defined  in (a)
National  Instrument  52-110 -- Audit  Committees ("NI 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
NI 52-110.  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 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 AOG 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 AOG's Audit Committee and will disclose such determination
in Advantage'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 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.

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

RESPONSIBILITIES AND DUTIES

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

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

      (b)   the Audit Committee is informed of each non-audit service; and

      (c)   the procedures do not include  delegation of the Audit  Committee's
            responsibilities to management.

      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.

                              INDUSTRY CONDITIONS

The oil  and  natural  gas  industry  is  subject  to  extensive  controls  and
regulations  governing  its  operations  (including  land tenure,  exploration,
development,  production, refining,  transportation,  and marketing) imposed by
legislation enacted by various levels of government and with respect to pricing
and  taxation of oil and natural gas by  agreements  among the  governments  of
Canada,  Alberta,  British Columbia,  and Saskatchewan,  all of which should be
carefully  considered  by  investors  in the oil and  gas  industry.  It is not
expected that any of these controls or  regulations  will affect our operations
in a manner  materially  different  than they  would  affect  other oil and gas
entities of similar size. All current  legislation is a matter of public record
and we are unable to predict what  additional  legislation or amendments may be
enacted.  Outlined  below are some of the  principal  aspects  of  legislation,
regulations and agreements governing the oil and gas industry.

PRICING AND MARKETING - OIL AND NATURAL GAS

The producers of oil are entitled to negotiate  sales  contracts  directly with
oil  purchasers,  with the result that the market  determines the price of oil.
Oil prices are  primarily  based on worldwide  supply and demand.  The specific
price depends in part on oil quality,  prices of competing  fuels,  distance to
market,  the value of refined products,  the supply/demand  balance,  and other
contractual  terms.  Oil  exporters  are also  entitled  to enter  into  export
contracts  with terms not exceeding one year in the case of light crude oil and
two years in the case of heavy crude oil, provided that an order approving such
export has been obtained from the National  Energy Board of Canada (the "NEB").
Any oil export to be made  pursuant  to a  contract  of longer  duration  (to a
maximum of 25 years)  requires an exporter to obtain an export licence from the
NEB and the issuance of such  licence  requires the approval of the Governor in
Council.

The price of  natural  gas is  determined  by  negotiation  between  buyers and
sellers.  Natural gas exported  from Canada is subject to regulation by the NEB
and the Government of Canada.  Exporters are free to negotiate prices and other
terms with purchasers, provided that the export contracts must continue to meet
certain  other  criteria  prescribed  by the NEB and the  Government of Canada.
Natural gas (other than propane,  butane and ethane) exports for a term of less
than two years or for a term of two to 20 years (in quantities of not more than
30,000 m3/day),  must be made pursuant to an NEB order.  Any


                                      61


natural gas export to be made  pursuant to a contract of longer  duration (to a
maximum of 25 years) or a larger  quantity  requires  an  exporter to obtain an
export  licence  from the NEB and the  issuance of such  licence  requires  the
approval of the Governor in Council.

The governments of Alberta,  British  Columbia,  and Saskatchewan also regulate
the  volume  of  natural  gas that may be  removed  from  those  provinces  for
consumption   elsewhere   based  on  such  factors  as  reserve   availability,
transportation arrangements, and market considerations.

PIPELINE CAPACITY

Although  pipeline  expansions are ongoing,  the lack of firm pipeline capacity
continues  to affect the oil and natural gas  industry and limit the ability to
produce and to market natural gas production. In addition, the pro-rationing of
capacity on the inter-provincial  pipeline systems also continues to affect the
ability to export oil and natural gas.

THE NORTH AMERICAN FREE TRADE AGREEMENT

The North  American Free Trade  Agreement  ("NAFTA")  among the  governments of
Canada,  United States of America,  and Mexico  became  effective on January 1,
1994.  NAFTA  carries  forward  most of the  material  energy  terms  that  are
contained in the Canada United States Free Trade  Agreement.  In the context of
energy resources,  Canada continues to remain free to determine whether exports
of energy  resources to the United  States or Mexico will be allowed,  provided
that any  export  restrictions  do not:  (i) reduce  the  proportion  of energy
resources  exported  relative  to  domestic  use  (based  upon  the  proportion
prevailing  in the most recent 36 month  period);  (ii) impose an export  price
higher than the domestic  price subject to an exception with respect to certain
voluntary measures which only restrict the volume of exports; and (iii) disrupt
normal  channels of supply.  All three  countries are prohibited  from imposing
minimum or maximum export or import price requirements,  provided,  in the case
of export price  requirements,  prohibition in any  circumstances  in which any
other  form of  quantitative  restriction  is  prohibited,  and in the  case of
import-price  requirements,  such  requirements  do not apply  with  respect to
enforcement of countervailing and anti-dumping orders and undertakings.

NAFTA contemplates the reduction of Mexican  restrictive trade practices in the
energy  sector by 2010 and prohibits  discriminatory  border  restrictions  and
export taxes.  NAFTA also  contemplates  clearer  disciplines  on regulators to
ensure fair implementation of any regulatory changes and to minimize disruption
of  contractual   arrangements  and  avoid  undue  interference  with  pricing,
marketing  and  distribution  arrangements,  which is  important  for  Canadian
natural gas exports.

PROVINCIAL ROYALTIES AND INCENTIVES

GENERAL

In  addition  to  federal   regulation,   each  province  has  legislation  and
regulations   which   govern  land   tenure,   royalties,   production   rates,
environmental   protection,   and  other  matters.  The  royalty  regime  is  a
significant  factor in the  profitability  of crude oil,  natural gas  liquids,
sulphur, and natural gas production. Royalties payable on production from lands
other than Crown lands are determined by negotiations between the mineral owner
and the  lessee,  although  production  from such  lands is  subject to certain
provincial taxes and royalties.  Crown royalties are determined by governmental
regulation  and are  generally  calculated  as a percentage of the value of the
gross  production.  The rate of royalties  payable generally depends in part on
prescribed reference prices, well productivity,  geographical  location,  field
discovery  date,  method of recovery,  and the type or quality of the petroleum
product produced.  Other royalties and royalty-like interests are, from time to
time,  carved out of the working interest  owner's interest through  non-public
transactions.  These are  often  referred  to as  overriding  royalties,  gross
overriding royalties, net profits interests, or net carried interests.

Occasionally the governments of the western Canadian provinces create incentive
programs for  exploration  and  development.  Such  programs  often provide for
royalty rate reductions,  royalty holidays,  and tax credits, and are generally
introduced  when  commodity  prices  are low.  The  programs  are  designed  to
encourage  exploration and development  activity by improving earnings and cash
flow within the  industry.  Royalty  holidays and  reductions  would reduce the
amount  of Crown  royalties  paid by oil and gas  producers  to the  provincial
governments and would increase the net income and funds from operations of such
producers.  However,  the  trend  in  recent  years  has  been  for  provincial
governments  to  eliminate,


                                      62


amend  or  allow  such  incentive  programs  to  expire  without  renewal,  and
consequently few such incentive programs are currently operative.

The  Canadian  federal  corporate  income tax rate levied on taxable  income is
19.5% effective  January 1, 2008 for active business income including  resource
income.  With the elimination of the corporate surtax effective January 1, 2008
and other rate reductions introduced in the October 2007 Economic Statement and
Notice of Ways and Means  Motion,  the federal  corporate  income tax rate will
decrease to 15% in three steps: 19% on January 1, 2009, 18% on January 1, 2010,
18.5% on January 1, 2011, and 15% on January 1, 2012.

ALBERTA

In Alberta,  companies  are  granted the right to explore,  produce and develop
petroleum  and  natural gas  resources  in exchange  for  royalties,  bonus bid
payments  and rents.  Currently,  the amount of  royalties  that are payable is
influenced  by the oil  production,  density of the oil, and the vintage of the
oil.  Originally,  the  vintage  classified  oil in "new  oil"  and  "old  oil"
depending  on when the oil pools were  discovered.  If the pool was  discovered
prior to March 31, 1974 it is considered "old oil", if it was discovered  after
March 31, 1974 and before  September 1, 1992, it is considered  "new oil".  The
Alberta government  introduced in 1992 a Third Tier Royalty with a base rate of
10% and a rate cap of 25% for oil pools discovered after September 1, 1992. The
new oil royalty  reserved to the Crown has a base rate of 10% and a rate cap of
30%.  The old oil  royalty  reserved  to the Crown has a base rate of 10% and a
rate cap of 35%.

The royalty reserved to the Crown in respect of natural gas production, subject
to various incentives,  is between 15% and 30%, in the case of new natural gas,
and  between  15% and 35%, in the case of old  natural  gas,  depending  upon a
prescribed  or corporate  average  reference  price.  Natural gas produced from
qualifying intervals in eligible gas wells spudded or deepened to a depth below
2,500  metres is also  subject  to a  royalty  exemption,  the  amount of which
depends on the depth of the well.

Oil sands projects are subject to a specific  regulation made effective July 1,
1997,  and expiring June 30, 2007,  which,  among other things,  determines the
Crown's share of crude and processed oil sands products.

Regulations  made  pursuant to the MINES AND  MINERALS ACT  (Alberta)  provided
various  incentives  for  exploring  and  developing  oil  reserves in Alberta.
However,  the Alberta Government  announced in August of 2006 that four royalty
programs were to be amended, a new program was to be introduced and the Alberta
Royalty Tax Credit Program ("ARTC") was to be eliminated,  effective January 1,
2007.  The  programs  affected by this  announcement  are: (i) Deep Gas Royalty
Holiday;  (ii) Low Productivity Well Royalty Reduction;  (iii) Reactivated Well
Royalty Exemption;  and (iv) Horizontal Re-Entry Royalty Reduction. The program
being  introduced is the Innovative  Energy  Technologies  Program (the "IETP")
which is intended to promote the producers' investment in research,  technology
and innovation for the purposes of improving  environmental  performance  while
creating  commercial  value.  The IETP provides  royalty  reductions  which are
presumed to reduce  financial  risk.  Alberta  Energy will be the one to decide
which  projects  qualify and the level of support  that will be  provided.  The
deadline  for the IETP's  third round of  applications  was May 31,  2007.  The
successful applicants have not yet been announced and it appears,  based on the
previous two rounds, that the selection process can take at least 8 months. The
technical  information  gathered  from this program is to be made public once a
two year confidentiality period expires.

On October 25, 2007, the Alberta government released a report entitled "The New
Royalty  Framework"  (the "NRF")  containing  the  government's  proposals  for
Alberta's new royalty regime,  which is scheduled to be effective on January 1,
2009. The proposed NRF includes new royalty  formulas for  conventional oil and
natural  gas that  will  operate  on  sliding  scales  that are  determined  by
commodity prices and well productivity. Substantial legislative, regulatory and
systems  updates will be introduced  before changes  become fully  effective in
January 2009.

BRITISH COLUMBIA

Producers  of oil and  natural  gas in the  Province  of British  Columbia  are
required to pay annual  rental  payments  with  respect to the Crown leases and
royalties and freehold production taxes in respect of oil and gas produced from
Crown and  freehold  lands.  The amount  payable as a royalty in respect of oil
depends on the type of oil,  the value of the oil, the quantity of oil produced
in a month, and the vintage of the oil. Generally,  the vintage of oil is based
on the  determination  of whether  the oil


                                      63


is produced from a pool discovered  before October 31, 1975 (old oil),  between
October 31, 1975, and June 1, 1998 (new oil), or after June 1, 1998 (third-tier
oil). The royalty rates are calculated in three stages, which take into account
the  vintage of the oil,  if the oil  produced  has  already  been sold and any
royalty  exempt  value  applicable  (exempt  wells).  Oil  produced  from newly
discovered  pools may be exempt  from the payment of a royalty for the first 36
months of production or 11,450m(3)  produced,  whichever  comes first;  and the
royalties  for  third-tier  oil are the lowest  reflecting  the higher costs of
exploration and extraction that the producers would incur.  The royalty payable
on natural gas is  determined  by a sliding  scale based on a reference  price,
which is the greater of the price  obtained by the  producer,  and a prescribed
minimum price.  However,  when the reference price is below the select price (a
parameter used in the royalty rate formula),  the royalty rate is fixed.  As an
incentive for the  production and marketing of natural gas, which may have been
flared,  natural gas produced in association  with oil has a lower royalty then
the royalty payable on non-conservation gas.

On May 30,  2003,  the Ministry of Energy and Mines for the Province of British
Columbia  announced  an Oil and Gas  Development  Strategy  for the  Heartlands
("STRATEGY").   The  Strategy  is  a  comprehensive  program  to  address  road
infrastructure,  targeted  royalties  and  regulatory  reduction,  and  British
Columbia service sector opportunities. In addition, the Strategy will result in
economic and employment  opportunities  for  communities in British  Columbia's
heartlands.

Some of the financial incentives in the Strategy include:

      o     Royalty  credits  of  up  to  $30  million   annually  towards  the
            construction,  upgrading, and maintenance of road infrastructure in
            support of resource  exploration and  development.  Funding will be
            contingent upon an equal contribution from industry.

      o     Changes  to  provincial  royalties:   new  royalty  rates  for  low
            productivity  natural gas to enhance marginally  economic resources
            plays,  royalty  credits  for deep gas  exploration  to locate  new
            sources of natural gas, and royalty  credits for summer drilling to
            expand the drilling season.

On February 27, 2007 the  Government  of British  Columbia  unveiled the Energy
Plan  outlining  the  Province's  strategy  towards the  environment  and which
includes  targeting  for zero  net  greenhouse  gas  emissions,  promoting  new
investments  in  innovation,  and  becoming the world's  leader in  sustainable
environmental management. For this purpose, on December 18, 2007 proposals were
sought for  applications  to the  Innovative  Clean  Energy  Fund,  in order to
attract new technologies that will help solve energy and environmental  issues.
With  regards to the oil and gas industry  the  objective  is to achieve  clean
energy   through   conservation   and  energy   efficient   practices,   whilst
competitiveness is advocated in order to attract investment for the development
of the oil and gas sector.  Among the changes to be implemented  are: (i) a new
of Net Profit Royalty Program; (ii) the creation of a Petroleum Registry; (iii)
the  establishment of an  infrastructure  royalty program  (combining roads and
pipelines); (iv) the elimination of routine flaring at producing wells; (v) the
creation of policies  and measures for the  reduction  of  emissions;  (vi) the
development of unconventional  resources such as tight gas and coalbed gas; and
(vii) new the Oil and Gas Technology Transfer Incentive Program that encourages
the  research,  development  and use of  innovative  technologies  to  increase
recoveries from existing reserves and promotes  responsible  development of new
oil and gas reserves.

SASKATCHEWAN

In  Saskatchewan,  the amount payable as a royalty in respect of oil depends on
the vintage of the oil,  the type of oil,  the  quantity  of oil  produced in a
month, and the value of the oil. For Crown royalty and freehold  production tax
purposes,  crude oil is considered "heavy oil",  "southwest designated oil", or
"non-heavy oil other than southwest  designated oil". The conventional  royalty
and production tax  classifications  ("fourth tier oil"  introduced  October 1,
2002,  "third  tier  oil",  "new  oil",  or "old  oil") of oil  production  are
applicable to each of the three crude oil types. The Crown royalty and freehold
production  tax structure for crude oil is price  sensitive and varies  between
the base  royalty  rates of 5% for all "fourth  tier oil" to 20% for "old oil".
Marginal royalty rates are 30% for all "fourth tier oil" to 45% for "old oil".

The amount  payable as a royalty in respect of natural gas is  determined  by a
sliding  scale based on a reference  price  (which is the greater of the amount
obtained by the producer and a prescribed minimum price), the quantity produced
in a given month,  the type of natural gas, and the vintage of the natural gas.
As an incentive for the  production and marketing of natural gas which may have
been flared,  the royalty rate on natural gas produced in association  with oil
is less than on  non-associated  natural  gas. The royalty and  production  tax
classifications  of gas production are "fourth tier gas" introduced


                                      64


October 1, 2002,  "third tier gas", "new gas", and "old gas". The Crown royalty
and freehold  production tax for gas is price  sensitive and varies between the
base  royalty  rate of 5% for  "fourth  tier  gas" and 20% for "old  gas".  The
marginal  royalty  rates are between 30% for "fourth tier gas" and 45% for "old
gas".

On October 1, 2002, the following changes were made to the royalty and tax
regime in Saskatchewan:

      o     A new Crown royalty and freehold  production tax regime  applicable
            to  associated  natural gas (gas  produced  from oil wells) that is
            gathered  for use or  sale.  The  royalty/tax  will be  payable  on
            associated  natural  gas  produced  from an oil well  that  exceeds
            approximately 65 thousand cubic metres in a month.

      o     A modified  system of  incentive  volumes and  maximum  royalty/tax
            rates  applicable to the initial  production from oil wells and gas
            wells with a finished  drilling  date on or after  October 1, 2002,
            was  introduced.  The incentive  volumes are  applicable to various
            well types and are subject to a maximum  royalty rate of 2.5% and a
            freehold production tax rate of zero per cent.

      o     The  elimination  of the re entry and short section  horizontal oil
            well  royalty/tax  categories.  All  horizontal  oil  wells  with a
            finished  drilling date on or after  October 1, 2002,  will receive
            the "fourth tier" royalty/ tax rates and new incentive volumes.

In 1975, the Government of Saskatchewan introduced a Royalty Tax Rebate ("RTR")
as a response to the federal government disallowing crown royalties and similar
taxes as a deductible  business expense for income tax purposes.  As of January
1, 2007,  the remaining  balance of any unused RTR limited in its carry forward
to five years since the federal  government  had the  initiative to reintroduce
the full deduction of provincial resource royalties from federal and provincial
taxable income.

On June 19, 2007, the Government of Saskatchewan introduced the Orphan Well and
Facility Liability  Management Program pursuant to the amendment of the OIL AND
GAS CONSERVATION ACT and the OIL AND GAS  CONSERVATION  REGULATIONS,  1985. The
program includes a security deposit, which has two purposes: (i) preventing the
individual with  insufficient  financial  capability from acquiring oil and gas
wells or  facilities;  and (ii) in the case of a  bankrupt  company,  the funds
cover for the decommissioning and reclaiming of orphan property.  An additional
change  introduced  is the  mandatory  licensing  of all  upstream  oil and gas
facilities in Saskatchewan.

LAND TENURE

Crude  oil  and  natural  gas  located  in  the  western   provinces  is  owned
predominantly by the respective provincial governments.  Provincial governments
grant rights to explore for and produce oil and natural gas pursuant to leases,
licences,  and permits for varying terms from two years,  and on conditions set
forth in provincial legislation including requirements to perform specific work
or make  payments.  Oil and natural gas located in such  provinces  can also be
privately  owned and rights to explore for and produce such oil and natural gas
are granted by lease on such terms and conditions as may be negotiated.

ENVIRONMENTAL REGULATION

The  oil and  natural  gas  industry  is  currently  subject  to  environmental
regulations pursuant to a variety of provincial and federal  legislation.  Such
legislation  provides  for  restrictions  and  prohibitions  on the  release or
emission of various substances produced in association with certain oil and gas
industry  operations.  In addition,  such  legislation  requires  that well and
facility  sites be abandoned  and reclaimed to the  satisfaction  of provincial
authorities.   Compliance  with  such   legislation  can  require   significant
expenditures  and a breach of such  requirements  may result in  suspension  or
revocation  of  necessary  licenses and  authorizations,  civil  liability  for
pollution damage, and the imposition of material fines and penalties.

Environmental legislation in the Province of Alberta has been consolidated into
the ENVIRONMENTAL  PROTECTION AND ENHANCEMENT ACT (Alberta) (the "EPEA"), which
came into force on  September  1, 1993,  and the OIL AND GAS  CONSERVATION  ACT
(Alberta)  (the  "OGCA").  The  EPEA  and OGCA  impose  stricter  environmental
standards,   require  more  stringent  compliance,   reporting  and  monitoring
obligations,  and  significantly  increased  penalties.  In 2006,  the  Alberta
Government  enacted  regulations  pursuant to the EPEA to  specifically  target
sulphur oxide and nitrous oxide emissions from industrial


                                      65


operations  including  the oil and gas  industry.  In addition,  the  reduction
emission  guidelines  outlined in the CLIMATE  CHANGE AND EMISSIONS  MANAGEMENT
AMENDMENT ACT came into effect on July 1, 2007. Under this legislation, Alberta
facilities  emitting more than 100,000  tonnes of greenhouse  gases a year must
reduce their  emissions  intensity  by 12%.  Industries  have three  options to
choose  from in order  to meet  the  reduction  requirements  outlined  in this
legislation, and these are: (i) by making improvement to operations that result
in  reductions;  (ii) by  purchasing  emission  credits  from other  sectors or
facilities  that have  emissions  below the  100,000  tonne  threshold  and are
voluntarily  reducing their  emission;  or (iii) by contributing to the Climate
Change and Emissions Management Fund. Industries can either choose one of these
options  or a  combination  thereof.  We  will  be  committed  to  meeting  its
responsibilities   to  protect  the   environment   wherever  it  operates  and
anticipates  making  increased  expenditures  of both a capital  and an expense
nature  as a  result  of  the  increasingly  stringent  laws  relating  to  the
protection  of the  environment,  and will be taking  such steps as required to
ensure compliance with the EPEA and similar  legislation in other jurisdictions
in which it  operates.  We  believe  that we are in  material  compliance  with
applicable  environmental  laws and  regulations.  We also  believe  that it is
reasonably  likely that the trend towards  stricter  standards in environmental
legislation and regulation will continue.

In January 24,  2008,  the Alberta  Government  announced a new climate  change
action plan that will cut Alberta's  projected 400 million  tonnes of emissions
in half by 2050.  This plan is based on three  areas:  (i) carbon  capture  and
storage, which will be mandatory for IN SITU oil sand facilities that use heavy
fuels for steam generation;  (ii) energy conservation and efficiency; and (iii)
greening  production  through increased  investment in clean energy technology,
including supporting research on new oil sands extraction processes, as well as
the  funding of  projects  that  reduce the cost of  separating  CO2 from other
emissions supporting carbon capture and storage.

British Columbia's ENVIRONMENTAL ASSESSMENT ACT became effective June 30, 1995.
This  legislation  rolls the previous  processes for the review of major energy
projects   into  a  single   environmental   assessment   process  with  public
participation  in the  environmental  review process.  On February 27, 2007 the
Government  of  British  Columbia   unveiled  the  Energy  Plan  outlining  the
Province's  strategy  towards the environment and which includes  targeting for
zero net greenhouse gas emissions, promoting new investments in innovation, and
becoming the world's leader in sustainable environmental  management.  For this
purpose,  on December 18, 2007  proposals were sought for  applications  to the
Innovative  Clean Energy Fund, in order to attract new  technologies  that will
help solve  energy and  environmental  issues.  With regards to the oil and gas
industry the  objective is to achieve  clean energy  through  conservation  and
energy efficient  practices,  whilst  competitiveness  is advocated in order to
attract  investment for the  development  of the oil and gas sector.  Among the
changes to be implemented  are: (i) a new of Net Profit Royalty  Program;  (ii)
the  creation  of  a  Petroleum   Registry;   (iii)  the  establishment  of  an
infrastructure  royalty  program  (combining  roads  and  pipelines);  (iv) the
elimination of routine flaring at producing wells; (v) the creation of policies
and  measures  for  the  reduction  of  emissions;   (vi)  the  development  of
unconventional  resources  such as tight gas and coalbed gas; and (vii) new the
Oil and Gas Technology Transfer Incentive Program that encourages the research,
development  and use of innovative  technologies  to increase  recoveries  from
existing  reserves  and  promotes  responsible  development  of new oil and gas
reserves.  Furthering  these  initiatives,  on February 19, 2008 the provincial
Government announced that starting on July 1, 2008, provided the legislation is
approved; a revenue-neutral carbon tax will be applied to all fossil fuels used
in the  Province.  The tax would be phased  in, and the  initial  rate would be
based on CO2e of $10 per tonne  for the  first  six  months of 2009 and $15 per
tonne for the last six months of 2009, following $5 per tonne increases on July
of every year until 2012. Tax credits and  reductions  will be used in order to
offset the tax revenues that the Government would receive otherwise.

In December,  2002, the  Government of Canada  ratified the Kyoto Protocol (the
"PROTOCOL").  The  Protocol  calls  for  Canada to reduce  its  greenhouse  gas
emissions to 6% below 1990  "business-as-usual"  levels  between 2008 and 2012.
Given  revised  estimates  of Canada's  normal  emissions  levels,  this target
translates  into an  approximately  40% gross  reduction  in  Canada's  current
emissions.  It  remains  uncertain  whether  the Kyoto  target of 6% below 1990
emission  levels  will be  enforced  in  Canada.  The  Federal  Government  has
introduced  legislation  aimed at reducing  greenhouse  gas  emissions  using a
"intensity  based" approach,  the specifics of which have yet to be determined.
Bill C-288,  which is intended to ensure that Canada  meets its global  climate
change  obligations  under the Protocol,  was passed by the House of Commons on
February  14,  2007.  On April 26, 2007,  the Federal  Government  released its
Action Plan to Reduce  Greenhouse  Gases and Air Pollution  (the "ACTION PLAN")
also  known as  ecoACTION  which  includes  the  regulatory  framework  for air
emissions.  This Action Plan covers not only large industry,  but regulates the
fuel  efficiency of vehicles and the  strengthening  of energy  standards for a
number of energy using  products.  The Government of Canada and the Province of
Alberta  released on January 31,  2008 the final  report of the  Canada-Alberta
ecoENERGY Carbon Capture and Storage Task Force, which recommends among others:
(i)   incorporating   carbon  capture  and  storage  into  Canada's  clean  air
regulations;  (ii)  allocating  new funding into projects  through  competitive
process; and targeting research to lower the cost of technology.


                                      66


Given the  evolving  nature of the debate  related  to  climate  change and the
control of  greenhouse  gases and resulting  requirements,  it is not currently
possible to predict either the nature of those requirements or the impact on us
and our  operations  and  financial  condition at this time.  As details of the
implementation  of this legislation have not yet been announced,  the effect of
our operations cannot be determined at this time.

TRENDS

There  are a number of trends  that  have  been  developing  in the oil and gas
industry  during  the past  several  years that  appear to be shaping  the near
future of the business.

The  first  trend is the  volatility  of  commodity  prices.  Natural  gas is a
commodity  influenced by factors  within North America.  A tight  supply-demand
balance for  natural  gas causes  significant  elasticity  in pricing,  whereas
higher  than  average  storage  levels  tend to depress  natural  gas  pricing.
Drilling activity, weather, fuel switching and demand for electrical generation
are all factors that affect the supply-demand balance.  Changes to any of these
or other factors create price volatility.

Crude oil is influenced  by the world  economy,  Organization  of the Petroleum
Exporting  Countries'  ability to adjust  supply to world  demand and  weather.
Crude oil prices have been kept high by political events causing disruptions in
the supply of oil and concern over potential  supply  disruptions  triggered by
unrest in the Middle East and more  recently  have been impacted by weather and
increased storage levels.  Political events trigger large fluctuations in price
levels.

The impact on the oil and gas  industry  from  commodity  price  volatility  is
significant.  During periods of high prices, producers generate sufficient cash
flows  to  conduct  active  exploration   programs  without  external  capital.
Increased  commodity  prices  frequently  translate  into very busy periods for
service suppliers triggering premium costs for their services.  Purchasing land
and properties  similarly  increase in price during these  periods.  During low
commodity  price periods,  acquisition  costs drop, as do internally  generated
funds  to spend on  exploration  and  development  activities.  With  decreased
demand, the prices charged by the various service suppliers also decline.

A  second  trend  within  the  Canadian  oil and  gas  industry  is the  fairly
consistent "renewal" of private and small junior oil and gas companies starting
up business.  These  companies  often have  experienced  management  teams from
previous industry  organizations that have disappeared as a part of the ongoing
industry  consolidation.  Many are  able to  raise  capital  and  recruit  well
qualified personnel. We will have to compete with these companies and others to
attract qualified personnel.

A third trend  currently  affecting  the oil and gas  industry is the impact on
capital markets caused by investor  uncertainty in the North American  economy.
The capital market volatility in Canada has also been affected by uncertainties
surrounding  the economic  impact that the  Protocol,  and other  environmental
initiatives,  will  have on the  sector  and,  in  more  recent  times,  by the
enactment of the SIFT Tax  legislation  relating to trusts,  such as the Trust.
Under the  legislation,  trusts  such as the Trust  will be liable for tax at a
rate consistent with the taxes currently imposed on corporations  commencing in
January 2011,  provided that the SIFT  experiences  only "normal growth" and no
"undue  expansion" before then, in which case the tax could be imposed prior to
the January 2011  deadline.  See "RISK FACTORS - CHANGES IN  LEGISLATION - SIFT
TAX".

Generally during the past year, the economic  recovery  combined with increased
commodity prices has caused an increase in new equity financings in the oil and
gas industry,  although the level of same was negatively  impacted by enactment
of the SIFT Tax. We will compete  with  numerous  new  companies  and their new
management  teams  and  development  plans  in  its  access  to  capital.   The
competitive  nature of the oil and gas industry  will cause  opportunities  for
equity financings to be selective.  We may have to rely on internally generated
funds to conduct our exploration and developmental programs.

                                  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.


                                      67


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  2007  averaging  US$72.37 WTI as
compared to an average of US$66.35 WTI in 2006, an increase of 9%.

AECO monthly index prices  averaged  $6.61/Mcf in 2007 as compared to $6.98/Mcf
in 2006, a decrease of 5%. 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 gas related
technologies  such  as  three-


                                      68


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
gas and operating  costs,  future capital  expenditures


                                      69


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 $710,000,000. 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

All phases of the oil and natural gas business present  environmental risks and
hazards and are subject to  environmental  regulation  pursuant to a variety of
federal,  provincial  and  local  laws and  regulations.  Compliance  with such
legislation can require significant expenditures and a breach may result in the
imposition of fines and penalties, some of which may be material. Environmental
legislation  is evolving in a manner  expected to result in stricter  standards
and enforcement,  larger fines and liability and potentially  increased capital
expenditures  and operating  costs.  In 2002, the Government of Canada ratified
the Protocol  which calls for Canada to reduce its  greenhouse gas emissions to
specified  levels.  There has been much public  debate with respect to Canada's
ability to meet these  targets and the  Government's  strategy  or  alternative
strategies with respect to climate change and the control of greenhouse gases.

On March 10, 2008,  the  Government  of Canada  released  "Turning the Corner -
Taking  Action to Fight  Climate  Change"  (the  "UPDATED  ACTION  PLAN") which
provides  some  additional  guidance with respect to the  Government's  plan to
reduce greenhouse gas emissions by 20% by 2020 and by 60% to 70% by 2050.

The Updated Action Plan is primarily directed towards industrial emissions from
certain specified industries including the oil sands, oil and gas and refining.
The  Updated  Action  Plan is  intended  to create a carbon  emissions  trading
market,  including an offset system,  to provide incentive to reduce greenhouse
gas  emission  and  establish a market  price for carbon.  There are  mandatory
reductions of 18% from the 2006 baseline  starting in 2010 and an additional 2%
in  subsequent  years


                                      70


for existing facilities.  This target will be applied to regulated sectors on a
facility-specific,  sector-wide or corporate  basis;  in the case of oils sands
production,  petroleum refining, natural gas pipelines and upstream oil and gas
the  target  will  be  considered   facility-specific  (sectors  in  which  the
facilities are complex and diverse,  or where emissions are affected by factors
beyond the control of the facility  operator).  Emissions from new  facilities,
which are those built  between  2004 and 2011,  will be based on a cleaner fuel
standard to encourage  continuous emissions intensity reductions over time, and
will be granted a 3-year  grace  period  during  which no  emissions  intensity
targets  will  apply.  Targets  will  begin  to  apply  on the  fourth  year of
commercial  operation  and the  baseline  will be the  third  year's  emissions
intensity, with a 2% continuous annual emission intensity improvement required.
The  definition  of new facility  also includes  greenfield  facilities,  major
expansions  constituting  more than a 25%  increase  in a  facility's  physical
capacity,  as well as  transformations  to a facility that involve  significant
changes to its  processes.  For upstream oil and gas and natural gas pipelines,
it will be applied using a  sector-specific  approach.  For the oil sands,  its
application will be process-specific, oil sands plants built in 2012 and later,
those which use heavier  hydrocarbons,  up-graders and IN-SITU  production will
have  mandatory  standards  in 2018 that will be based on  carbon  capture  and
storage.

In the following regulated sectors,  the Updated Action Plan will apply only to
facilities exceeding a minimum annual emissions threshold: (i) 50,000 tonnes of
CO2  equivalent  per year for natural gas  pipelines;  (ii) 3,000 tonnes of CO2
equivalent per upstream oil and gas facilities; and (iii) 10,000 boe/d/company.
These proposed  thresholds are significantly  stricter than the current Alberta
regulatory threshold of 100,000 tonnes of CO2 equivalent per year per facility.

Four  separate  compliance  mechanisms  are  provided  in  respect of the above
targets:  Technology  Fund  contributions,  offset credits,  clean  development
credits and credits for early action.  The most significant of these compliance
mechanisms,  at least  initially,  will be the  Technology  Fund and for  which
regulated entities will be able to contribute in order to comply with emissions
intensity reductions.  The contribution rate will increase over time, beginning
at $15 for the 2010-12 period, rising to $20 in 2013, and thereafter increasing
at the nominal  rate of GDP growth.  Contribution  limits will  correspondingly
decline from 70% in 2010 to 0% in 2018. Monies raised through  contributions to
the Technology  Fund will be used to invest in technology to reduce  greenhouse
gas emissions. Alternatively, regulated entities may be able to receive credits
for  investing  in  large-scale  and   transformative   projects  at  the  same
contribution rate and under similar requirements as mentioned above.

The offset system is intended to encourage emissions reductions from activities
outside of the regulated sphere, allowing non-regulated entities to participate
in and benefit from emissions reduction activities. In order to generate offset
credits,  project  proponents  must propose and receive  approval for emissions
reduction activities that will be verified before offset credits will be issued
to the project proponent.  Those credits can then be sold to regulated entities
for use in compliance or  non-regulated  purchasers  that wish to either cancel
the offset credits or bank them for future use or sale.

Under the Updated Action Plan, regulated entities will also be able to purchase
credits created through the Clean  Development  Mechanism of the Protocol.  The
purchase of such Emissions  Reduction Credits will be restricted to 10% of each
firm's regulatory obligation, with the added restriction that credits generated
through  forest sink projects  will not be available for use in complying  with
the Canadian regulations.

Finally,  a one-time  credit of up to 15 Mt worth of emissions  credits will be
awarded to regulated  entities for emissions  reduction  activities  undertaken
between 1992 and 2006. These credits will be both tradable and bankable.

Implementation of strategies for reducing  greenhouse gases whether to meet the
limits required by the Protocol or the new regulatory  framework,  could have a
material  impact on the nature of oil and  natural  gas  operations,  including
those of the Trust.  Given the evolving nature of the debate related to climate
change and the control of greenhouse  gases and resulting  requirements,  it is
not possible to predict at this time either the nature of those requirements or
the impact on the Trust and its  operations and financial  condition.  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
our 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


                                      71


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.

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 2007,  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 2007 to an
average $0.94 US/Cdn compared to $0.88 US/Cdn in 2006. 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 and the NYSE.

RELIANCE UPON THE SENIOR EXECUTIVES OF AOG

Unitholders  will be  dependent  upon the  management  of 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 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;


                                      72


o     assumptions  about future  commodity  prices,  production and development
      costs, severance and excise taxes, and capital expenditures;

o     initial production rates;

o     production decline rates;

o     ultimate recovery of reserves;

o     timing and amount of capital expenditures;

o     marketability of production;

o     future prices of oil and natural gas;

o     operating costs and royalties; and

o     other  government  levies that may be imposed over the producing  life of
      reserves.

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

DEPLETION OF RESERVES

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

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

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

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

RELIANCE UPON THIRD PARTY OPERATORS

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

ENFORCEMENT OF OPERATING AGREEMENTS

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


                                      73


operators to enforce the terms of the operating agreements;  thus,  Unitholders
will be dependent  upon us, as owner of the working  interest,  to enforce such
rights.

CHANGES IN LEGISLATION - SIFT TAX

New legislation  passed in June 2007 will apply a tax ("SIFT TAX") at the trust
level on  distributions  of certain  income from  publicly  traded  mutual fund
trusts,  known as specified  investment  flow-through  ("SIFT") trusts at rates
comparable to the combined  federal and  provincial  corporation  tax, and will
treat such  distributions as dividends to the unitholders.  The Trust is a SIFT
and  will be  subject  to the  SIFT  Tax.  The  SIFT  Tax  results  in  adverse
consequences to the Trust and certain Unitholders  (including most particularly
Unitholders  that are tax deferred,  or non-residents of Canada) and may impact
cash distributions from the Trust.

Trusts  that were in  existence  on  October  31,  2006 will  generally  have a
four-year  transition  period,  and will not be  subject  to the SIFT Tax until
January  1,  2011.  However,  the  new  legislation  provides  that  there  are
circumstances  under which an existing trust may lose its  transitional  relief
before 2011, including where the "normal growth" of a trust existing on October
31, 2006 is exceeded.

"Normal growth"  includes  equity growth within certain "safe harbour"  limits,
measured  by  reference  to a  SIFT's  market  capitalization  as of the end of
trading on October 31, 2006 (which  would  include only the market value of the
SIFT's  issued  and  outstanding  publicly-traded  trust  units,  and  not  any
convertible debt,  options or other interests  convertible into or exchangeable
for trust  units).  Those  safe  harbour  limits  are 40% for the  period  from
November 1, 2006 to December 31, 2007, and 20% each for calendar 2008, 2009 and
2010.  Moreover,  the safe harbour  limits are  cumulative,  so that any unused
limit for a period carries over into the subsequent  period. The Trust's market
capitalization  was  approximately  $1.6 billion as at October 31, 2006,  which
means that the Trust's safe harbour  amount for the period ending  December 31,
2007 was approximately $640 million, and is an additional $320 million for each
of 2008,  2009 and 2010. The Trust's growth since October 31, 2006 has not been
in excess of "normal growth".

While it is unlikely that the  restrictions  on "normal growth" will affect our
ability  to raise  the  capital  required  to  maintain  and grow our  existing
operations  in the ordinary  course,  they could  adversely  affect the cost of
raising capital and our ability to undertake more significant acquisitions.

Currently,  the SIFT Rules  provide  that the SIFT Tax rate will be the federal
general  corporate  income tax rate (which is  anticipated to be 16.5% in 2011,
and 15% in 2012) plus the  provincial  SIFT tax factor (which is set at a fixed
rate of 13%), for a combined SIFT tax rate of 29.5% in 2011, and 28% in 2012.

On February 26, 2008, the Minister of Finance announced, and on March 11, 2008,
draft  legislation was introduced (the "PROVINCIAL  SIFT TAX PROPOSAL"),  under
which the effect will be that instead of basing the provincial component of the
SIFT tax on a flat rate of 13%, the provincial  component will instead be based
on the general  provincial  corporate income tax rate in each province in which
the SIFT has a  permanent  establishment.  For  purposes  of  calculating  this
component of the tax, the general corporate  taxable income allocation  formula
will be used. Specifically, the Trust's taxable distributions will be allocated
to provinces by taking half of the aggregate of:

      o     that proportion of the Trust's taxable  distributions  for the year
            that the  Trust's  wages and  salaries in the  province  are of its
            total wages and salaries in Canada; and

      o     that proportion of the Trust's taxable  distributions  for the year
            that the Trust's  gross  revenues in the  province are of its total
            gross revenues in Canada.

Under the Provincial  SIFT Tax Proposal the Trust would likely be considered to
have a permanent  establishment  in Alberta,  where the  provincial tax rate in
2011 is expected to be 10%,  which will result in an effective SIFT Tax rate of
26.5% in 2011 and 25% in 2012. Taxable  distributions that are not allocated to
any province would instead be subject to a 10% rate constituting the provincial
component.  There can be no assurance,  however,  that the Provincial  SIFT Tax
Proposal will be enacted as proposed.


                                      74


The new  legislation  has  reduced  the  value of the  Trust  Units,  which has
increased  the cost to the  Trust of  raising  capital  in the  public  capital
markets.  In  addition  management  of AOG  believes  that  the SIFT  Tax:  (a)
substantially  eliminates  the  competitive  advantage that the Trust and other
Canadian  energy trusts enjoyed  relative to their  corporate  peers in raising
capital in a tax-efficient  manner, and (b) places the Trust and other Canadian
energy trusts at a competitive  disadvantage  relative to industry competitors,
including  U.S.  master  limited  partnerships,  which will  continue to not be
subject to entity level taxation.  The SIFT Tax also makes the Trust Units less
attractive as an acquisition  currency. As result, it may become more difficult
for the Trust to compete effectively for acquisition  opportunities.  There can
be no  assurance  that the Trust will be able to  reorganize  its legal and tax
structure to substantially mitigate the expected impact of the SIFT Tax.

No  assurance  can be  provided  that the SIFT Tax will not  apply to the Trust
prior to 2011, or that the income tax  legislation  will not be further changed
in a manner which affects the Trust and its Unitholders.

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.

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 2007 an estimated 70% 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.

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 of 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".

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  that
adversely affects us


                                      75


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 we 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
they invested during the period when reserves may


                                      76


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
is  expected  to develop  for such Long Term Notes or


                                      77


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 AOG 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 AOG 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.

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.

Additionally,  the reduced "Qualified  Dividend" rate of 15% tax applied to our
distributions  under current U.S. tax laws is scheduled to expire at the end of
2010 and there is no  assurance  that this  reduced tax rate will be renewed by
the U.S. government at such time.

Furthermore,  the SIFT Tax is anticipated to result in adverse tax consequences
to certain Unitholders including non-resident Unitholders.  See "RISK FACTORS -
CHANGES IN LEGISLATION - SIFT TAX".

NON-RESIDENT   UNITHOLDERS  ARE  SUBJECT  TO  FOREIGN   EXCHANGE  RISK  ON  THE
DISTRIBUTIONS THAT THEY MAY RECEIVE FROM THE TRUST.

Distributions  from the Trust are declared in Canadian dollars and converted to
foreign  denominated  currencies  at the  spot  exchange  rate  at the  time of
payment.  As a consequence,  investors are subject to foreign exchange risk. To
the extent that the Canadian  dollar  weakens with respect to the currency of a
non-resident,  the amount of the distribution will be reduced when converted to
the home currency of a non-resident.

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 four 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; 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;  and 4) submit an
executed annual written  affirmation,  as well as an interim  affirmation  each
time a change occurs to the Audit Committee.  We have reviewed the NYSE listing
standards  and confirm that our  corporate  governance  practices do not differ
significantly from such standards.

                                  SCHEDULE "A"

   REPORT OF MANAGEMENT AND DIRECTORS ON RESERVES DATA AND OTHER INFORMATION
                                (FORM 51-101F3)

Management  of Advantage Oil & Gas Ltd.  ("AOG") on behalf of Advantage  Energy
Income Fund (collectively,  the "TRUST") is responsible for the preparation and
disclosure of information with respect to the Trust's oil and gas activities in
accordance with securities regulatory  requirements.  This information includes
reserves data which are estimates of proved reserves and probable  reserves and
related  future net revenue as at December 31, 2007,  estimated  using forecast
prices and costs.

An independent  qualified reserves evaluator has evaluated the Trust's reserves
data. The report of the independent  qualified  reserves evaluator is presented
below.

The independent reserves evaluation committee of the Trust has:

      (a)   reviewed the Trust's  procedures  for providing  information to the
            independent qualified reserves evaluator;

      (b)   met with the independent  qualified reserves evaluator to determine
            whether any  restrictions  affected the ability of the  independent
            qualified reserves evaluator to report without reservation; and

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

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

      (a)   the content and filing with  securities  regulatory  authorities of
            Form  51-101F1  containing  reserves  data  and  other  oil and gas
            information;

      (b)   the filing of Form 51-101F2 which is the report of the  independent
            qualified reserves evaluator on the reserves data; and

      (c)   the content and filing of this report.

Because the  reserves  data are based on  judgments  regarding  future  events,
actual  results  will vary and the  variations  may be material.  However,  any
variations  should be consistent  with the fact that  reserves are  categorized
according to the probability of their recovery.

                            REPORT ON RESERVES DATA
             BY INDEPENDENT QUALIFIED RESERVES EVALUATOR OR AUDITOR
                                (FORM 51-101 F2)

To the Board of Directors of Advantage  Oil & Gas Ltd.,  on behalf of Advantage
Energy Income Fund (the "TRUST"):

1.    We have evaluated the Trust's  Reserves Data as at December 31, 2007. The
      reserves data are estimates of proved reserves and probable  reserves and
      related  future net  revenue as at December  31,  2007,  estimated  using
      forecast prices and costs.

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

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

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

4.    The  following  table  sets  forth  the  estimated   future  net  revenue
      attributed to proved plus probable  reserves,  estimated  using  forecast
      prices  and costs on a before tax basis and  calculated  using a discount
      rate of 10%,  included in the reserves data of the Trust  evaluated by us
      as of December 31, 2007, and identifies the respective  portions  thereof
      that we have  audited,  evaluated  and  reviewed  and  reported on to the
      Trust's management and Board of Directors:



                                                                               Net Present Value of Future Net Revenue

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

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

7.    Because  the  reserves  data are  based on  judgements  regarding  future
      events,  actual  results  will vary and the  variations  may be material.
      However,  any variations should be consistent with the fact that reserves
      are categorized according to the probability of their recovery.
