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

This  annual  information  form  contains  forward-looking   statements.   These
statements  relate  to future  events or the  Trust's  future  performance.  All
statements  other  than  statements  of  historical  fact  are   forward-looking
statements.  The  use  of any of the  words  "anticipate",  "plan",  "continue",
"estimate",   "expect",  "may",  "will",  "project",   "predict",   "potential",
"should",   "believe"   and  similar   expressions   are  intended  to  identify
forward-looking  statements.  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. The
Trust  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     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     geological, technical, drilling and processing problems; and

o     the other factors discussed under "Risk Factors".

These  factors  should not be construed as  exhaustive.  None of the Trust,  the
Manager,  nor AOG  undertakes  any  obligation to publicly  update or revise any
forward-looking statements.

                          ADVANTAGE ENERGY INCOME FUND

Corporate Structure

Advantage Energy Income Fund,  Advantage Oil & Gas Ltd. and Advantage Investment
Management Ltd.

Advantage   Energy  Income  Fund  is  an  entity  that  provides   monthly  cash
distributions  to its  Unitholders.  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.

AOG is an oil and natural  gas  exploitation  and  development  company  that is
wholly-owned  by the Trust.  It was originally  incorporated  in 1979 as Westrex
Energy Corp. ("Westrex").  Through a plan of arrangement under the ABCA, Westrex
merged with Search  Energy Inc. on December  31,  1996,  and changed its name to
Search  Energy Corp.  ("Search") on January 2, 1997.  The  management of Westrex
was, for the most part,  replaced with the management of Search.  The merger was
accounted for as a "reverse  take-over" in  accordance  with Canadian  generally
accepted accounting principles.

Effective  May 24,  2001,  all of the issued and  outstanding  common  shares of
Search were acquired by AcquisitionCo,  a corporation wholly-owned by the Trust,
and Search and  AcquisitionCo  were then  amalgamated  and  continued as "Search
Energy Corp.".  On July 26, 2001, Search acquired all of the shares of Due West.
Due West's oil and natural gas  properties  were  comprised  of mainly long life
natural  gas and  light  oil  reserves,  many of  which  are  operated  by major
exploration and development companies.  Effective August 1, 2001, Search and Due
West were amalgamated and continued as "Search Energy Corp.".  Effective January
1, 2002 Search  acquired the Gascan Assets.  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.  On December 2, 2003 AOG acquired
all of the issued and outstanding shares of Markwest Resources Canada Corp.

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

The head  office  of the  Trust  and the  Manager  and the head  office  and the
registered  office  of AOG is  located  at Suite  3100,  150 -6th  Avenue  S.W.,
Calgary,  Alberta T2P 3H7.  The  registered  office of the Manager is located at
Suite 3700, 400 - 3rd Avenue S.W., Calgary, Alberta, T2P 4H2.

Notes:

(1)   The Unitholders own 100% of the Trust.

(2)   Cash distributions are made to Unitholders  monthly based upon the Trust's
      cash flow.

(3)   AOG has two  wholly-owned  subsidiaries,  namely  Best  Pacific  Resources
      (U.S.) Inc. and Spirit Waste Management  Inc., both of which  corporations

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

                       GENERAL DEVELOPMENT OF THE BUSINESS

History and Development

Search Energy Corp.

2001

During  the  fall of 2000 and in  early  2001,  management  of  Search  reviewed
strategic  alternatives and considered  possible methods for enhancing value for
shareholders  and ensuring the  continued  growth of Search.  In February  2001,
after  reviewing a variety of alternatives  and proposals,  management of Search
began to evaluate  the  benefits  that might  accrue to its  shareholders  if it
reorganized itself into an income trust.  Management requested that the Board of
Directors give consideration to such reorganization. On February 23 and February
26,  2001,  the Board of  Directors  met to consider  various  alternatives  for
Search,  including the  reorganization of Search into an income trust. After due
deliberation and  consideration of other  alternatives  available to Search,  on
February  28,  2001 the Board of  Directors  retained a third  party  advisor to
assist Search in the  evaluation of the  reorganization  proposal.  The Board of
Directors met on three further occasions and, after extensive review of Search's
asset base and detailed  production  cash flow modeling,  the Board of Directors
concluded that the best alternative available to Search for maximizing value for
shareholders  would be to convert  Search into an oil and gas income trust.  See
"General  Development  of the  Business - History  and  Development  - Advantage
Energy Income Fund".

On April 1, 2001, the Board of Directors unanimously approved the Reorganization
Agreement and on April 12, 2001, the Board of Directors unanimously approved the
Arrangement Agreement.

Advantage Energy Income Fund

2001

The  Arrangement  Agreement  provided  for  implementation  of  the  Arrangement
pursuant  to Section 193 of the ABCA.  On May 24,  2001,  each of the  following
events occurred in the following sequence:

1.    the shareholder  rights plan of Search and all  outstanding  rights issued
      pursuant thereto were terminated;

2.    all of the right,  title and interest of shareholders in the Common Shares
      were transferred to AcquisitionCo in exchange for  AcquisitionCo  Units on
      the basis of one  AcquisitionCo  Unit for every four Common  Shares  held,
      resulting in the  acquisition  by  AcquisitionCo  of all of the issued and
      outstanding Common Shares;

3.    all of the  right,  title  and  interest  of  former  shareholders  in the
      AcquisitionCo  Units were  transferred  to the Trust in exchange for Trust
      Units of the Trust on the basis of one Trust  Unit for each  AcquisitionCo
      Unit,  resulting in the  acquisition by the Trust of all of the issued and
      outstanding AcquisitionCo common shares and 14% Notes;

4.    all right, title and interest of former Search  optionholders who executed
      an  option   cancellation   agreement   exchanged   their   options   with
      AcquisitionCo for AcquisitionCo Units which were, in turn,  transferred to
      the Trust in  exchange  for Trust Units on the basis of one Trust Unit for
      each  AcquisitionCo  Unit. Any remaining options which were not subject to
      an option  cancellation  agreement  and which had not, as at May 24, 2001,
      been  exercised by the  optionholder,  were deemed to have been  exchanged
      with the Trust for  options to purchase  Trust Units which were,  in turn,
      exercised for Trust Units on May 25, 2001; and

5.    Search and  AcquisitionCo  amalgamated  and continued as one  corporation,
      and:

      (a)   all of the issued and  outstanding  Common Shares of Search,  all of
            which were then held by  AcquisitionCo,  were cancelled  without any
            repayment of capital; and

      (b)   the amalgamated  corporation  continued as "Search Energy Corp." and
            adopted the articles of incorporation of AcquisitionCo.

The Trust  Units  commenced  trading on the TSX on May 29, 2001 under the symbol
"AVN.UN".

On July 26, 2001 Advantage  acquired all of the issued and outstanding shares of
Due West, a private light oil and natural gas company with working  interests in
several  well-established  properties.  The Trust acquired all the shares of Due
West at a price of $2.24 per  share,  for an  aggregate  cash  consideration  of
$59.68  million  (the "Due West  Acquisition").  Advantage  funded  the Due West
Acquisition using its existing credit facilities.

On October 4, 2001,  Advantage  issued  5,000,000 Trust Units to the public at a
price of $7.50 per Trust Unit for gross proceeds of $37,500,000.  On October 11,
2001,  Advantage  issued an  additional  750,000  Trust  Units  pursuant  to the
exercise  of the  underwriters'  over-allotment  option  at a price of $7.50 per
Trust Unit for  additional  gross  proceeds of  $5,625,000.  The  aggregate  net
proceeds of $43,125,000 were used by Advantage to reduce its debt (a substantial
portion of which was incurred to fund the Due West Acquisition),  to fund future
acquisitions and capital expenditures, and for general corporate purposes.

On November 28, 2001,  Advantage and the Vendors entered into the Share Purchase
Agreement  providing for the  acquisition  by the Trust of all of the issued and
outstanding  securities of Newco,  which company,  as of the closing date of the
Asset  Transfer,  was the legal and beneficial  owner of the Gascan Assets.  The
effective  date of the  Gascan  Acquisition  was  January  1, 2002 with  closing
occurring on January 4, 2002. The net cash consideration payable by the Trust in
respect of the Gascan Acquisition was $69 million prior to adjustments.

On December 18, 2001,  Advantage issued 6,014,500 Trust Units to the public at a
price of $7.65  per  Trust  Unit for  gross  proceeds  of  $46,010,925.  The net
proceeds of the issue were used by Advantage  to repay a portion of  Advantage's
long term debt, some of which was incurred in connection with the acquisition of
the Gascan Assets owned by Newco.

                                       11


2002

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

The first annual and special  meeting of Unitholders  was held on June 25, 2002.
At such meeting,  Unitholders  considered and approved various matters including
the name change from "Search  Energy Corp." to "Advantage  Oil & Gas Ltd.",  the
addition of a class of non-voting  common shares for AOG, certain  amendments to
the Trust  Indenture and the  pre-authorization  of private  placements of Trust
Units during the ensuing 12-month period.

On September 10, 2002, Advantage completed an asset exchange transaction whereby
it  acquired  additional  interests  in  producing  natural  gas  properties  at
Vermilion,  Alberta  in  consideration  for  Advantage's  interest  in heavy oil
properties  located in  Wainwright,  Alberta.  The exchange was  structured as a
property swap with Advantage  neither  receiving nor paying any cash in relation
to the transaction.  Based upon the reserve engineering reports of Sproule dated
July 1, 2002 and January 1, 2002, the Fund acquired  approximately 14.7 bcf (2.5
mmboe) of  established  natural gas  reserves at  Vermilion  in exchange for 2.2
mmboe of established heavy oil reserves, of which 61% were classified as proved.

On  September  30,  2002,  Advantage  announced  that  it had  entered  into  an
acquisition agreement with Best Pacific providing for the purchase of all of the
issued and  outstanding  common  shares of Best  Pacific,  including  all shares
issued upon the exercise of outstanding  options and warrants (the "Best Pacific
Shares"),  on the basis of $1.25 cash  consideration for each Best Pacific Share
(the  "Offer").  The Offer was made by formal  take-over bid circular  which was
mailed on October  11,  2002.  The Offer  expired on  November  18,  2002,  with
Advantage  acquiring 95% of the Best Pacific  Shares on such date and completing
the  compulsory  acquisition  of the  remaining  5% of the Best  Pacific  Shares
effective November 21, 2002.

The acquisition of Best Pacific had a net purchase price,  after adjustments and
fees, of  approximately  $53.4 million,  which amount includes the assumption of
approximately $21.7 million of net debt.

The  properties  owned  by Best  Pacific  consisted  primarily  of high  working
interest  natural gas and light oil properties  located in southern  Alberta and
southeastern Saskatchewan.

In  conjunction  with the  acquisition of Best Pacific,  Advantage  announced on
September 30, 2002 that it had signed an agreement providing for the offering on
a bought deal basis of $55,000,000 aggregate principal amount of Debentures. The
Debentures  have a coupon of 10%, mature on November 1, 2007 and are convertible
into Trust Units at a price of $13.30 per Trust Unit. Interest is payable on the
Debentures  semi-annually,  with the first  interest  payment to occur on May 1,
2003.  The  offering  of  Debentures  closed on October 18,  2002,  with the net
proceeds of the offering used to fund the acquisition of Best Pacific, to reduce
bank indebtedness and for general corporate purposes.

2003

On January 24, 2003,  Advantage  announced the  appointment of Peter Hanrahan to
the  position of Chief  Financial  Officer in addition to his prior  position as
Controller.

At an  annual  and  special  meeting  of  Unitholders  held  on  May  28,  2003,
Unitholders  considered and approved various matters including amendments to the
Trust  Indenture,  the issuance of up to 1,500,000 Trust Units to the Manager in
payment  of  its  performance  fee  under  the  Management   Agreement  and  the
pre-authorization  of private  placements  of Trust Units  during the ensuing 12
month period.

On July 8, 2003, Advantage completed the issue, by way of short form prospectus,
of  $30,000,000  principal  amount  of  9%  convertible  unsecured  subordinated
debentures through a syndicate of underwriters. The convertible debentures had a
face value of $1,000  each with a coupon of 9%,  maturing  on August 1, 2008 and
are  convertible  into Trust Units at $17.00 per Trust Unit. The net proceeds of
the offering were used to fund an expanded  capital  expenditure  program and to
repay debt.

On December 8, 2003,  Advantage  completed a second issue,  by way of short form
prospectus, of 5,100,000 Trust Units at $15.75 per Trust Unit for gross proceeds
of $80,325,000 and $60,000,000  aggregate principal amount of 8 1/4% convertible
unsecured

                                       12


subordinated  debentures  through a syndicate of  underwriters.  The convertible
debentures had a face value of $1,000 each with a coupon of 8 1/4%,  maturing on
February 1, 2009 and are convertible  into Trust Units at $16.50 per Trust Unit.
The net proceeds of the offering were used to fund the  acquisition of MarkWest,
to reduce amounts  outstanding  under  Advantage's  credit  facility and to fund
drilling and exploitation capital expenditures.

In  conjunction  with the completion of the December  financing,  Advantage also
announced the completion of the MarkWest  acquisition.  The acquisition was made
for total cash consideration of $96,800,000 prior to adjustments.

                   DESCRIPTION OF THE BUSINESS AND OPERATIONS

Advantage Energy Income Fund

The Trust is a limited purpose trust and is restricted to:

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

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

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

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

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

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

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

In accordance  with the terms of the Trust  Indenture,  the Trust will make cash
distributions  to Trust  Unitholders of the interest  income earned from the 14%
Notes, royalty income earned on the Royalty, dividends (if any) received on, and
amounts,  if any, received on redemption of, Common Shares and Preferred Shares,
and income and  distributions  received  from any  Permitted  Investments  after
expenses and capital  expenditures,  any cash  redemptions  of Trust Units,  and
other  expenditures.  See "Additional  Information  Respecting  Advantage Energy
Income Fund - Cash Distributions".

Advantage Oil & Gas Ltd.

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

The Trust  employs  a  strategy  to  maintain  production  from  AOG's  existing
production  base while focusing  capital  expenditures  on low-risk  development
opportunities. AOG utilizes financial hedges, when deemed appropriate, to manage
and reduce the volatility in commodity prices. See "Risk Factors". AOG generally
sells  or  farms  out  higher  risk  projects  while  actively  pursuing

                                       13


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 the Trust's  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  and the  issuance  of  additional  Trust  Units from  treasury,
maintaining prudent leverage.

Significant Acquisitions

Effective October 1, 2003,  Advantage acquired all of the shares of MarkWest,  a
wholly-owned   subsidiary  of  MarkWest   Hydrocarbon,   Inc.,  for  total  cash
consideration  of  $96,800,000  prior to  adjustments.  The MarkWest  Properties
consist primarily of natural gas assets located in southeast Alberta and central
Alberta which at the date of acquisition was producing approximately 4,448 boe/d
(approximately 91% of which is natural gas). Approximately 98% of the production
from the  MarkWest  Properties  is  operated by MarkWest  with  MarkWest  having
approximately  a 78%  average  working  interest  in  such  production.  Audited
financial  statements  as at and  for the  year  ended  December  31,  2002  and
unaudited financial  statements as at and for the six months ended June 30, 2003
are attached hereto as Schedule "A".

Effective  January 1, 2002,  Advantage  acquired  the  Gascan  Assets.  Selected
pro-forma combined operational  information,  financial information,  as well as
production and drilling  histories for the Gascan Assets on an historical  basis
are set forth in the Trust's Renewal Annual Information Form dated May 16, 2002.

          STATEMENT OF RESERVES DATA AND OTHER OIL AND GAS INFORMATION

The statement of reserves data and other oil and gas information set forth below
(the  "Statement")  is  dated  December  31,  2003.  The  effective  date of the
Statement  is December  31, 2003 and the  preparation  date of the  Statement is
April 19, 2004.

Disclosure of Reserves Data

The  reserves  data set forth  below  (the  "Reserves  Data")  is based  upon an
evaluation by Sproule Associates  Limited  ("Sproule") with an effective date of
December  31, 2003  contained  in a report of Sproule  dated April 19, 2004 (the
"Sproule Report"). The Reserves Data summarizes the oil, liquids and natural gas
reserves of the Corporation and the net present values of future net revenue for
these reserves using  constant  prices and costs and forecast  prices and costs.
The Reserves Data conforms with the requirements of National  Instrument  51-101
Standards of Disclosure  for Oil and Gas Activities  ("NI  51-101").  Additional
information  not required by NI 51-101 has been presented to provide  continuity
and additional  information which we believe is important to the readers of this
information.  Advantage  Energy  Income  Fund  engaged  Sproule  to  provide  an
evaluation of proved and proved plus  probable  reserves and no attempt was made
to evaluate possible reserves.

All of the Trust's reserves are in Canada and, specifically, in the provinces of
Alberta, British Columbia and Saskatchewan.

It should not be assumed that the estimates of future net revenues  presented in
the tables below  represent the fair market value of the  reserves.  There is no
assurance that the constant prices and costs assumptions and forecast prices and
costs assumptions will be attained and variances could be material. The recovery
and reserve  estimates of the Trust's crude oil, natural gas liquids and natural
gas reserves  provided  herein are estimates only and there is no guarantee that
the  estimated  reserves will be  recovered.  Actual crude oil,  natural gas and
natural  gas  liquid  reserves  may be greater  than or less than the  estimates
provided herein.

Note:

(1)   The evaluation as at December 31, 2002 was prepared using National  Policy
      2-B reserves definitions. Under those definitions,  probable reserves were
      adjusted  by a factor  to  account  for the  risk  associated  with  their
      recovery.  The Trust previously  applied a risk factor of 50% in reporting
      probable  reserves.  Under NI 51-101 reserves  definitions,  estimates are
      prepared such that the full proved plus probable reserves are estimated to
      be  recoverable  (proved plus  probable  reserves are  effectively a "best
      estimate").  The above  reconciliation  reflects current probable reserves
      versus  previous risk adjusted  (50%)  probable  reserves  reported by the
      Trust.

Other Oil and Gas Information

Oil and Gas Properties

The  following is a  description  of  Advantage's  principal oil and natural gas
properties on production or under  development  as at January 1, 2004.  The term
"net", when used to describe Advantage's share of production, means the total of
Advantage's  working  interest  share before  deduction  of  royalties  owned by
others.  Reserve amounts are stated, before deduction of royalties,  at December
31, 2004, based upon escalating cost and price assumptions  (gross) as evaluated
in the Sproule Report (see  "Description  of the Business and Operations Oil and
Natural Gas Reserves"). Unless otherwise specified, gross and net acres and well
count  information are as at January 1, 2004.  Information in respect of current
production is 2003 exit  production,  net to Advantage,  except where  otherwise
indicated.

      Medicine Hat, Alberta

The Medicine Hat area is located in  southeastern  Alberta where Advantage has a
100% working interest in 24 sections of land.  Production in the area comes from
all of the main shallow gas  formations  including the Medicine Hat "A", "C" and
"D" sands,  both the Upper and Lower  Milk  River,  as well as the Second  White
Specks  sands.  When the  property  was  acquired in January 2002 there were 115
wells  producing  5.2  mmcf/d  of  natural  gas.  In  2002  and  2003,   several
recompletions  along with an additional 164 wells were drilled on this property.
Late in 2003 and continuing into early 2004, an additional 57 wells were drilled
and will be completed  during 2004.  Exiting  2003,  this property was producing
18.6  mmcf/d  from  approximately  300 wells.  Another 43 wells are  planned for
drilling  and are  expected  to be  on-stream  during the  second  half of 2004.
Compression  capacity was also increased in late 2003 by approximately 10 mmcf/d
to accommodate added production from the 2004 drilling programs.

Sproule  evaluated  Advantage's  reserves in the area and  assigned  73.8 bcf of
proved  natural gas reserves  and 8.3 bcf of probable  reserves.  As such,  this
property is Advantage's largest property on an assigned reserves basis.

      Wainwright and Kinsella, Alberta

These  properties  cover varying  working  interests  averaging more than 80% in
approximately   175  sections  of  land,   located  in  east  central   Alberta,
approximately 40 kilometers northwest of Wainwright,  Alberta.  Current combined
production  from these  areas is 5.6  mmcf/d.  In 2002,  Advantage  swapped  out
virtually all of its heavy oil assets which were  concentrated  in this area for
producing  natural  gas  assets in  Advantage's  other  core area of  Vermilion,
immediately to the north of this property.

Natural gas production occurs from the Manville Group and Viking Formations. All
production  occurs from shallow  depths of between 450 and 700 meters.  The Fund
operates  95% of its  natural  gas  production  in this area and owns a majority
interest in and  operates an  extensive  gas  gathering  system tying into three
Advantage-operated gas compression facilities

                                       21


Advantage has downspaced  almost a township of land to allow for the drilling of
two Viking wells per section.  In 2003,  Advantage  drilled 23.3 net wells which
encountered a combination of Viking and Upper Mannville  zones.  The Viking zone
represents  long life  reserves  with moderate  producing  rates.  Advantage has
approximately  2 1/2  townships of land covered  with  three-dimensional  ("3D")
seismic to aid in the selection of these drilling locations.

Sproule  evaluated  Advantage's  proved  reserves in the Wainwright and Kinsella
areas  and  assigned  7.7 bcf of  natural  gas and 4.0  mbbls  of oil.  Probable
reserves  for  Advantage  in this area were  evaluated  by Sproule at 6.1 bcf of
natural gas and 0.6 mbbls of oil.

      Stoddart/North Pine, British Columbia

The Stoddart/North Pine area lies immediately  northwest of the town of Fort St.
John in  northeast  British  Columbia.  The  area  contains  multiple  producing
horizons,  predominantly natural gas from the Permian,  Belloy formation and oil
from the Triassic,  Charlie Lake  formation.  Production from this area has very
low  decline  rates,  is low cost and  required  minimal  capital  expenditures.
Advantage owns an interest in 30 producing wells (22 net) in the area. Advantage
operates  approximately  80% of the natural gas production and has a 40% working
interest in the oil production. The area includes 12,000 gross (9,176 net) acres
of undeveloped land.  Current production from this area is 4.1 mmcf/d of natural
gas and 233 bbls/d of light oil and NGLs.

Sproule evaluated  Advantage's proved reserves in the area and assigned 11.5 bcf
of natural gas and 477.9 mbbls of crude oil and NGLs.  In  addition,  3.1 bcf of
probable  natural gas  reserves  and 164.7 mbbls of probable  crude oil and NGLs
reserves have been assigned to this property.

      Shouldice, Alberta

The Shouldice area of southern  Alberta is located  approximately  45 kilometers
southeast of the city of Calgary.  Advantage has an average working  interest of
more  than 85% in 34  sections  of land and  operates  in  excess  of 90% of its
production. Much of this acreage is downspaced to accommodate additional stepout
and infill  drilling.  Natural gas  production  of  approximately  7.0 mmcf/d is
produced on a co-mingled  basis from the  Medicine  Hat sand with various  Belly
River Formation sands.

In addition to natural gas,  Advantage also produced 57 bbls/d of medium gravity
(33(degree)  API) crude  oil.  This  production  is from the  deeper,  Mannville
formation, Basal Quartz sands.

During 2003, 20 net wells were added to the existing 70 producers.  Both natural
gas and crude oil are produced and gathered  through company owned facilities of
varying  working  interests.  An  additional  38 new  locations are licenced for
drilling which will commence in the second  quarter of 2004.  Theses will target
the  Medicine  Hat and Belly River  Formations  with 5 targeting  the deeper Bow
Island Formation.  Advantage is adding an additional 4 mmcf/d of new compression
capacity to handle the expected production increase.

The Sproule  Report  assigns  14.4 bcf of proven  natural gas reserves and 100.2
mbbls of proven crude oil and NGLs to this  property.  In  addition,  3.2 bcf of
probable  natural gas  reserves  and 16.0 mbbls of  probable  crude oil and NGLs
reserves have been assigned to this property.

      Bantry, Alberta

Bantry is  located  immediately  east of the town of Brooks and  consists  of 86
sections of land ranging between 50 and 100% working interest, with over half at
100%.  This  property  was  acquired in December  2003 with the  acquisition  of
MarkWest Resources. Since the acquisition, 25 new wells were drilled of which 18
earned additional acreage through a farm-in  arrangement with a major integrated
oil company.  Eleven  additional  sections  will be earned  through this farm-in
arrangement in the first half of 2004.  Production occurs primarily from various
sandstones  within  the Bow  Island  Formation  as well as from  Basal  Colorado
Formation channel sandstones.  Drilling is shallow with average well depths less
than 1,000 meters.

Natural gas is gathered into  Advantage  operated  compression  and  dehydration
facilities  and  current net  production  from this area is  approximately  14.7
mmcf/d.  Advantage has added 15 mmcf/d gross of additional  compression capacity
in the first quarter of 2004 to handle additional volumes from the new drilling.
Completion and tie-in of the new drills has been delayed due to spring  break-up
but  production is  anticipated to be on-stream by the end of the second quarter
2004.

                                       22


The Sproule  Report assigns 19.5 bcf of proven natural gas reserves and 35 mbbls
of proven NGL  reserves  to this  property.  In  addition,  6.0 bcf of  probable
natural gas reserves and 10.7 mbbls of probable NGL reserves  have been assigned
to this property.

      Nevis, Alberta

The Nevis  property  was  acquired  in  December  2003 with the  acquisition  of
Markwest  Resources.  Situated  50 km  east  of  Red  Deer,  Nevis  consists  of
approximately  32 sections of land with an average  working  interest  over 75%.
Natural gas production occurs from numerous shallow depth horizons including the
Edmonton,  Belly  River and Viking  formations.  Oil and natural gas is produced
from several slightly deeper reservoirs in the Glauconite, Ostacod and Ellerslie
formations of the Mannville Group.  Recent drilling in the Wabamun  formation is
developing  oil and natural  gas  production  from 2 to 4 meter thick  carbonate
reservoirs at the top of the formation, which occurs at moderate depths of 1,600
meters.

Current net  production to Advantage is 3.6 mmcf/d of natural gas and 302 bbls/d
of crude oil and NGLs.  Advantage operates 90% of its Nevis properties.  Natural
gas is gathered  through  company owned pipelines and processed at a third party
plant. Oil is trucked from single well batteries.

The Sproule  Report  assigns 9.5 bcf of proven  natural gas  reserves  and 917.3
mbbls of proven crude oil and NGLs reserves to this property.  In addition,  4.5
bcf of probable  natural gas reserves and 952.5 mbbls of risked  probable  crude
oil and NGLs reserves have been assigned to this property.

Forward Contracts

In March and April of 2003 Advantage  entered into costless collar  contracts on
approximately  60% of its natural gas production  (net of royalties).  Advantage
does not currently have any oil hedges in place.  The specific volumes and terms
of such commitments are set forth below:



       Type of Commitment               Average Fixed Price             Volume                   Term of Commitment

Additional Information Concerning Abandonment and Reclamation Costs

Advantage  estimates  the  costs  to  abandon  and  reclaim  all its shut in and
producing wells, facilities, gas plants, pipelines, batteries and satellites. No
estimate of salvage  value is netted  against the  estimated  cost.  Advantage's
model for estimating the amount and timing of future abandonment and reclamation
expenditures  was done on an operating area level.  Estimated  expenditures  for
each operating area are based upon Sproule's methodology, which details the cost
of abandonment and reclamation  for the major  properties that Advantage  holds.
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.

Advantage  estimates that they will incur  reclamation and abandonment  costs on
1,157.6 net  producing  and  non-producing  wells.  Costs to abandon and reclaim
these wells totals  $38.9  million  ($10.8  million  discounted  at 10%) and are
included  in the  estimate  of future  net  revenue.  The  additional  liability
associated with pipelines and facilities  reclamation  costs was estimated to be
$60 million ($0.5 million discounted at 10%), and was not deducted in estimating
future net revenue.  Facility  reclamation costs are scheduled to be incurred in
the year following the end of the reserve life of its associated  reserves under
the assumption that decommissioning of plant/facilities are mobile assets with a
long useful life.

Abandonment and reclamation costs included in the estimate of future net revenue
for the next three years are $0.7 million in 2004, $1.3 million in 2005 and $0.9
million in 2006.

Notes:

(1)   Before deduction of royalties.

(2)   Production  prices are net of costs to transport the product to market and
      net of hedging gains and losses.

(3)   Royalties are net of ARC.

(4)   This figure includes all field operating expenses.

(5)   Advantage does not record royalties and operating  expenses on a commodity
      basis.  Information  in respect of royalties  and  operating  expenses for
      crude oil and NGLs ($/bbl) and natural gas ($/mcf) has been  determined by
      allocating  royalties and expenses on an area by area basis based upon the
      relative  volume of  production  of crude oil and NGLs ($/bbl) and natural
      gas ($/mcf) in those areas.

(6)   Information  in respect of netbacks  received for crude oil & NGLs ($/bbl)
      and natural gas ($/mcf) is calculated using operating  expense figures for
      crude oil and NGLs  ($/bbl) and natural gas  ($/mcf),  which  figures have
      been estimated. See note (5) above.

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

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

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

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

      (d)   provide improved recovery systems.

                                       26


      "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:

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

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

      (c)   dry hole contributions and bottom hole contributions;

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

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

      "Gross" means:

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

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

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

      "Net" means:

      (a)   in relation to the Trust's interest in production and reserves,  the
            Trust's interest (operating and non-operating) share after deduction
            of  royalties  obligations,  plus the  Trust's  royalty  interest in
            production or reserves.

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

      (c)   in relation to the Trust's interest in a property, the total area in
            which the Trust has an interest  multiplied by the working  interest
            owned by the Trust.

      "NI 51-101" means National  Instrument  51-101 Standards of Disclosure for
      Oil and Gas Activities;

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 upon

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

o     the use of established technology; and

o     specified economic conditions.

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

                                       27


      (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:

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

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

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

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

Levels of Certainty for Reported Reserves

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

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

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

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

    REPORT OF MANAGEMENT AND DIRECTORS ON RESERVES DATA AND OTHER INFORMATION

Management of Advantage are  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 consist of the following:

      (a)   (i)   proved and proved plus probable oil and gas reserves estimated
                  as at December 31, 2003 using forecast prices and costs; and

                                       28


            (ii)  the related estimated future net revenue; and

            (iii) proved and proved plus probable oil and gas reserves estimated
                  as at December 31, 2003 using constant prices and costs; and

            (iv)  the related estimated future net revenue.

Sproule Associates Limited  ("Sproule") has evaluated the Trust's reserves data.
The report of Sproule is presented below.

The independent reserves evaluation committee of the Trust has

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

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

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

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

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

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

      (g)   the content and filing of this report.

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

                             REPORT ON RESERVES DATA

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

1.    We have  evaluated the Trust's  reserves data as at December 31, 2003. The
      reserves data consist of the following:

      (a)   (i)   proved and proved plus probable oil and gas reserves estimated
                  as at December 31, 2003 using forecast prices and costs; and

            (ii)  the related estimated future net revenue; and

      (b)   (i)   proved oil and gas reserves  estimated as at December 31, 2003
                  using constant prices and costs; and

                                       29


            (ii)  the related estimated future net revenue.

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

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

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

4.    The following  table sets forth the estimated  future net revenue  (before
      deduction of income taxes)  attributed  to proved plus probable  reserves,
      estimated using forecast prices and costs and calculated  using a discount
      rate of 10 percent,  included in the reserves data of the Trust  evaluated
      by us for the year ended  December 31, 2003, and identifies the respective
      portions thereof that we have audited, evaluated and reviewed and reported
      on to the Trust's board of directors:

      all material respects, been determined and are in accordance with the COGE
      Handbook.  We express no opinion on the reserves data that we reviewed but
      did not audit or evaluate.

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

         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 April 30, 2004,  39,502,390 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  interests in two classes as follows:  (i)  described and
designated  as "Trust  Units",  which are  entitled  to the  rights,  subject to
limitations,  restrictions  and  conditions set out in the Trust  Indenture,  as
summarized  herein; and (ii) described and designated as "Special Voting Units",
which shall be issued to a trustee and shall be entitled to such number of votes
at  meetings  of Trust  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 Board of
Directors.  The Special  Voting  Units give AOG the  flexibility  to acquire the
securities  of  another  issuer  in  consideration   for  securities  which  are
ultimately  exchangeable  for Trust Units. All Trust Units are of the same class
with equal rights and privileges. Each Trust Unit is

                                       30


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  upon  liquidation,  is fully paid
and  non-assessable  and entitles the holder thereof to one vote at all meetings
of Trust 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.  As holders of Trust
Units in the Trust,  the Trust  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 price per
Trust Unit is a function of  anticipated  distributable  income from AOG and the
combined  ability of the Board of Directors and the Manager to effect  long-term
growth  in the  value of the  Trust.  The  market  price of the  Trust  Units is
sensitive  to a variety of market  conditions  including,  but not  limited  to,
interest  rates,  commodity  prices  and the  ability  of the  Trust to  acquire
additional assets. Changes in market conditions may adversely affect the trading
price of the Trust Units.

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.

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  Trust  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 the  Trust's  assets.
Pursuant to the Trust Indenture, the Trust 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 the Trust must  contain a provision to the effect that such  obligation  will
not be binding upon Trust Unitholders  personally.  Notwithstanding the terms of
the Trust Indenture,  Trust Unitholders may not be protected from liabilities of
the Trust 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 Trust Unitholders of this nature arising is considered  unlikely in
view of the  fact  that  the  sole  business  activity  of the  Trust 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.

The business of the Trust and its  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 the Trust  Unitholders  for
claims  against the Trust,  including  obtaining  appropriate  insurance,  where
available, for the operations of AOG and having written agreements, signed by or
on behalf  of the  Trust,  include a  provision  that such  obligations  are not
binding upon Trust Unitholders personally.

Issuance of Trust Units

The Trust  Indenture  provides that Trust Units or rights to acquire Trust Units
may be issued at the times, to the persons,  for the  consideration,  and on the
terms and conditions that the Board of Directors determines. The Trust Indenture
also provides that immediately after any pro rata distribution of Trust Units to
all Trust 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.

                                       31


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 14% Notes, 10?% Notes, royalty income from the
Royalty,  dividends  on or in respect of shares of AOG received by the Trust and
income from the Permitted  Investments;  less: (i)  administrative  expenses and
other  obligations of the Trust; and (ii) amounts which may be paid by the Trust
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 the Trust 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 the
Trust does 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.

The Trust derives  interest income from its holdings of the Notes. The 14% Notes
bear interest at 14% per annum,  payable monthly and will mature on December 31,
2031, subject to extension for an additional 20-year term at the instance of the
Board of  Directors,  with the approval  thereof by resolution of the holders of
the Notes if the Trust  does not then hold  substantially  all of the 14% Notes.
The 10?% Notes bear interest at 10?% per annum,  payable on May 1 and November 1
in each  calendar  year and  mature on  December  31,  2012.  The 9?% Notes bear
interest  at 9?% per annum  while the 8 1/2% Notes bear  interest  at 8 1/2% per
annum and both are payable on February 1 and August 1 in each  calendar year and
both mature on December 31, 2013.  It is expected  that the Trust's  income will
generally be limited to: (i) the interest  received on the  principal  amount of
the Notes; (ii) royalty income received on the Royalty;  and (iii) dividends (if
any) received on shares of AOG. See "Additional Information Respecting Advantage
Oil & Gas Ltd. - Notes".

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

Redemption Right

Trust Units are  redeemable  at any time on demand by the holders  thereof  upon
delivery to the Trust of the certificate or certificates representing such Trust
Units,  accompanied by a duly completed and properly  executed notice requesting
redemption.  Upon receipt of the redemption  request by the Trust, 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.

                                       32


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

If a Trust  Unitholder  is not entitled to receive cash upon the  redemption  of
Trust Units as a result of the foregoing limitations,  then the Redemption Price
for such Trust Units shall be the Fair Market  Value  thereof (as defined in the
Trust Indenture), as determined by the Trustee in the circumstances described in
subparagraphs  (ii) and  (iii)  above,  and  shall,  subject  to any  applicable
regulatory approvals,  be paid and satisfied by way of distribution in specie of
a pro rata  number of 14% 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 14% Notes will be distributed and
where the number of 14% Notes to be  received by a Trust  Unitholder  includes a
fraction,  such number  shall be rounded to the next lowest  whole  number.  The
Trust shall be entitled to all interest paid, or accrued and unpaid,  on the 14%
Notes on or before the date of the distribution in specie. If the Trust does not
hold 14% Notes having a sufficient  principal amount  outstanding to effect such
payment,  the Trust will be entitled to create  and,  subject to any  applicable
regulatory approvals, issue in satisfaction of the Redemption Price its own debt
securities (the  "Redemption  Notes") having terms and conditions  substantially
the same as the 14% Notes, and with recourse of the holder limited to the assets
of the Trust. Holders of such 14% 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".  14% 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.  14% Notes or
Redemption  Notes which may be  distributed  in specie to Trust  Unitholders  in
connection  with a  redemption  will not be listed on any stock  exchange and no
market is expected to develop in such 14% Notes or Redemption Notes.

Meetings of Trust Unitholders

The Trust Indenture  provides that meetings of Trust  Unitholders must be called
and held for, among other matters,  the election or removal of the Trustee,  the
appointment or removal of the auditors of the Trust,  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 the assets of the Trust 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 Trust  Unitholders  will be called and held  annually  for,
among other things, the election of the Trustee,  the appointment of auditors of
the Trust, and the direction of the Trustee as to the selection of the directors
of AOG. A  resolution  appointing  or  removing a Trustee,  the  auditors of the
Trust,  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 Trust  Unitholders.
The  balance  of the  foregoing  matters  must be passed by at least 66?% of the
votes cast at a meeting of Trust Unitholders called for such purpose.

A meeting of Trust  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.

Trust  Unitholders  may attend  and vote at all  meetings  of Trust  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 Trust
Unitholders.  The next  annual  and  special  meeting  of Trust  Unitholders  is
scheduled for May 26, 2004.

                                       33


Information and Reports

The Trust will furnish to Trust 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 Trust  Unitholders'  tax returns under the Tax Act and  equivalent
provincial legislation.

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

The Board of  Directors  will  ensure  that AOG  provides  the Trust with proper
disclosure  as  to  its  business  and  financial   operations   and  sufficient
information  and  materials  on a timely  basis to allow  the  Trust to meet its
public reporting  requirements.  With respect to material changes,  the Board of
Directors will ensure that AOG provides timely disclosure to the Trust 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 Trust
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  Trust  Unitholders  and,  in  connection
therewith,  shall  exercise  that  degree of care,  diligence  and skill  that a
reasonably prudent trustee would exercise in comparable circumstances.

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

Delegation of Authority, Administration and Trust Governance

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

                                       34


Decision-Making

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

Liability of the Trustee

The Trustee, its directors,  officers, employees,  shareholders and agents shall
not be liable to any Trust Unitholder or any other person, in tort,  contract or
otherwise,  in connection  with any matter  pertaining to the Trust or the Trust
Fund,  arising  from the exercise by the Trustee of any powers,  authorities  or
discretion conferred under the Trust Indenture,  including,  without limitation,
any action taken or not taken in good faith in reliance upon any documents  that
are, prima facie, properly executed,  any depreciation of, or loss to, the Trust
Fund  incurred  by  reason  of the  sale of any  asset,  any  inaccuracy  in any
evaluation provided by the Manager or any other appropriately  qualified person,
any  reliance  upon any such  evaluation,  any  action or  failure to act of the
Manager,  AOG, or any other person to whom the Trustee has,  with the consent of
AOG,  delegated any of its duties  hereunder,  or any other action or failure to
act  (including  failure to compel in any way any former  trustee to redress any
breach of trust or any failure by the Manager or AOG to perform its duties under
or delegated to it under the Trust Indenture or any material  contract),  unless
such liabilities arise out of the gross  negligence,  wilful default or fraud of
the  Trustee  or any of its  directors,  officers,  employees,  shareholders  or
agents.  If the Trustee has  retained an  appropriate  expert,  adviser or legal
counsel  with  respect to any matter  connected  with its duties under the Trust
Indenture or any material  contract,  the Trustee may act or refuse to act based
upon the advice of such expert,  adviser or legal counsel, and the Trustee shall
not be  liable  for and  shall be  fully  protected  from any loss or  liability
occasioned  by any  action or  refusal  to act based upon the advice of any such
expert, adviser or legal counsel. In the exercise of the powers,  authorities or
discretion 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?% of the votes  cast at a meeting  of the Trust  Unitholders  called for such
purpose.

The Trustee  may,  without the approval of the Trust  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 the Trust 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 Trust 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 Trust Unitholders;

                                       35


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.

Unitholders  will be asked to  approve,  by way of special  resolution,  certain
proposed  changes to the Trust  Indenture  at the annual and special  meeting of
Unitholders  scheduled for May 26, 2004. The specific details of such amendments
are set forth in the Trust's Information  Circular - Proxy Statement dated April
16, 2004.

Private Placements

At the upcoming annual and special meeting of Unitholders,  Unitholders  will be
asked to authorize the sale by the Trust in one or more private placements of up
to  15,000,000  Trust Units on such terms as may be  determined  by the Board of
Directors  and by the  Trust.  It is  anticipated  that the Trust may  undertake
private placements to complete  acquisitions or raise equity capital in order to
fund capital  expenditures or acquisitions that may enhance the Trust's business
prospects.  The Trust will regularly evaluate opportunities which will assist in
enhancing Trust Unitholder  value,  and the private  placement of Trust Units or
instruments  convertible  into Trust  Units will be  routinely  considered  as a
financing  alternative,  particularly  as a private  placement  can typically be
structured  to reduce the market  risk  associated  with  traditional  long form
public financings. The Trust obtained such approval last year in order to retain
the  flexibility to issue up to 18,000,000  Trust Units by private  placement in
2004. The Trust is not currently  considering  the specific terms of any private
placement pursuant to which it may issue Trust Units.

Any private placement must be undertaken in accordance with applicable corporate
law,  securities  legislation  and  stock  exchange  by-laws,   regulations  and
policies.  Among other things, such regulations limit the discount to the market
price at which the Trust Units may be sold pursuant to a private placement.

Some or all of the Trust Units offered by private  placement may be purchased by
insiders of the Trust or AOG.  The  issuance of greater  than 25% of the Trust's
issued and outstanding  Trust Units to a new or existing  Unitholder or group of
Unitholders  may  result  in a change of  control  of the  Trust or  enhance  an
existing  control  position.  To the extent  that Trust Units are  purchased  by
insiders,  persons having a significant or controlling interest in the Trust may
enhance their ownership position with respect to existing Unitholders who do not
participate  in the  private  placement.  Where  insiders  of the  Trust  or AOG
participate in any such private  placement,  the TSX may require evidence of the
approval of the majority of Unitholders,  excluding the participating  insiders,
to the private  placement.  Funds  received from any private  placement  will be
added  to the  Trust's  working  capital  to be  used  for  financing  programs,
projects, acquisitions, debt reduction or for general corporate purposes.

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 the
assets of the Trust in their entirety or substantially in their entirety, except
as part of an internal  reorganization of the assets of the Trust as approved by
the Board of Directors,  requires approval by at least 66?% of the votes cast at
a meeting of the Trust Unitholders.

Exercise of Voting Rights Attached to Common Shares

The Trust Indenture provides that the Trustee may vote securities of AOG held by
it at any meeting of  shareholders  of AOG as well as any Permitted  Investments
held,  from time to time,  as part of the Trust Fund which carry voting  rights.
However, the Trustee may not, under any circumstances  whatsoever,  vote any AOG
securities  or any other  Permitted  Investments  which carry  voting  rights to
authorize  the  sale,  lease  or  exchange  of all or  substantially  all of the
property of AOG or any other entity owned  directly or  indirectly  by the Trust
which  represents  more  than  51%  of the  Trust  Fund,  except  as  part  of a
reorganization  of AOG  and  any  one  or  more  directly  or  indirectly  owned
subsidiaries  of the Trust  without  the  approval of at least 66?% of the votes
cast at a meeting of the Trust Unitholders called for such purpose.

Distribution Policy

It is anticipated  that income to be received by the Trust 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 Trust  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  and  Preferred  Shares.  The Trust is the sole  holder of the issued and
outstanding  Common Shares.  There are no Non-Voting  Shares or Preferred Shares
issued and  outstanding.  The Trust 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 Board of Directors and
subject to  applicable  legal  restrictions,  entitled to receive any  dividends
declared by the Board of Directors on the Common  Shares.  The holders of Common
Shares are entitled to share  equally in any  distribution  of the assets of AOG
upon the  liquidation,  dissolution,  bankruptcy  or  winding-up of AOG or other
distribution of its assets among its  shareholders for the purpose of winding-up
its  affairs.   Such  participation  is  subject  to  the  rights,   privileges,
restrictions  and conditions  attaching to any instruments  having priority over
the Common Shares.

Non-Voting Shares

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

                                       39


Preferred Shares

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

14% Notes

The following is a summary of the material attributes and characteristics of the
14% Notes.  This summary does not purport to be complete and is qualified in its
entirety by reference to the provisions of 14% Note Indenture, pursuant to which
the 14% Notes are issued.

The  aggregate  principal  amount of the 14% Notes as at  December  31, 2003 was
$314,239,188  and the 14% Notes  mature on  December  31,  2031,  subject  to an
extension  for an additional  20-year  term.  The 14% Notes bear interest at the
rate of 14% per annum, payable monthly on the 15th day of the month (or, if such
day is not a Business  Day,  the first  Business  Day  thereafter)  for interest
earned during the preceding  month.  The principal and interest on the 14% Notes
are payable in lawful money of Canada.

The  14%  Notes  are  issuable  only  as   fully-registered   notes  in  minimum
denominations of $100.00 and integral multiples of $1.00.

Payment upon Maturity

On maturity and subject to any applicable subordination  restrictions,  AOG will
repay  the  indebtedness  represented  by the 14%  Notes by  paying  to the Note
Trustee,  in lawful money of Canada,  an amount equal to the principal amount of
the outstanding 14% Notes, together with accrued and unpaid interest thereon.

Redemption

The 14% Notes  will not be  redeemable  at the  option of AOG or by the  holders
thereof prior to maturity except in the limited circumstances  prescribed by 14%
Note  Indenture,   where  the  Board  of  Directors   believe  the  indebtedness
represented  by the 14% Notes could not be refinanced on maturity,  or where AOG
is  prevented  by  applicable   law  from  paying   dividends  or  making  other
distributions in respect of Common Shares.

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 14% Notes will be subordinated in right
of payment, as set forth in 14% Note Indenture,  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 14% Note  Indenture;  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 14% Note  Indenture;  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
14% Notes.  The 14% Note  Indenture  provides  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 14% Notes are  entitled to receive any  payment.
Any amount of property  received  contrary to these  provisions shall be held in
trust for and paid over to the holders of Senior Indebtedness.

                                       40


In the event of any creditor  proceedings,  the indebtedness  represented by the
14% 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 14% Notes in respect  of any  restructuring  or
arrangement proposal regarding AOG.

Default

The 14% Note Indenture  provides that any of the following  shall  constitute an
"Event of  Default":  (i) default in payment of the  principal  of the 14% Notes
when the same becomes due; (ii) the failure to pay the interest  obligations  of
the 14% Notes for a period  of 12  months;  (iii)  default  on any  indebtedness
exceeding   $5,000,000;   (iv)  certain  events  of   winding-up,   liquidation,
bankruptcy,  insolvency  or  receivership;  (v) the taking of  possession  by an
encumbrancer of all or substantially all of the property of AOG; or (vi) default
in the  observance or performance of any other covenant or condition of 14% Note
Indenture  and the  continuance  of such  default  for a period of 30 days after
notice in writing  has been given by the Note  Trustee  to AOG  specifying  such
default and requiring AOG to rectify the same.

Subordination Agreements

Pursuant  to the terms of 14% Note  Indenture,  the Note  Trustee may enter into
subordination  agreements with the holders of certain Senior  Indebtedness under
which the Note  Trustee,  on  behalf  of the  holders  of 14%  Notes,  may agree
directly with a holder of Senior  Indebtedness  in  implementation  of and/or in
addition to the  subordination  terms described under "Ranking"  directly above.
The Note Trustee may give a holder of Senior Indebtedness a power of attorney to
be exercised in any creditor  proceedings to enforce the terms thereof. The Note
Trustee  may also  agree to ensure  that any  transferee  of 14% Notes (or other
securities  of AOG) agrees to be bound by the  provisions  of the  subordination
agreements.

an amount  equal to not less than 5% of the  original  principal  amount  (being
$52,800,000 - the "Original  Principal Amount") provided,  however,  that during
the period  commencing  from the date of issue to  December  31,  2007 AOG shall
make, in aggregate, principal repayments on the 10 3/8% Notes of an amount equal
to not less than 50% of the Original Principal Amount.

Ranking

The Royalty Agreement

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

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

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

If AOG wishes to dispose  of any  properties  that will  result in  proceeds  in
excess of $5 million,  AOG's  board of  directors  is  required to approve  such
disposition.

Shareholder Agreement

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

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

      (k)   provide or arrange for all necessary  exploitation,  development and

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

1 and 2 above,  the Board of Directors  will  supervise  the  management  of the
business  and affairs of AOG,  including  the  business and affairs of the Trust
delegated to AOG, and, in particular:

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

4.    decisions relating to:

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

      (b)   the acquisition and  disposition of properties,  assets,  securities

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

      (d)   the establishment of credit facilities;

            any  exchange  and to  maintain  the  Trust's  status as a reporting
            issuer,  including  press  releases and material  change  reports as

      (g)   the  approval of any  amendment  to the  Management  Agreement,  the

            on behalf of the Trust,  and those matters as set forth in the Trust
            Indenture, that may be amended without the approval of Unitholders;

shall be subject to the approval of the Board of Directors.

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

In  exercising  its  powers and  discharging  its  duties  under the  Management
Agreement,  the Manager is required to exercise  that degree of care,  diligence
and skill that a  reasonably-prudent  operator and manager in respect of oil and
gas  properties in western

                                       46


Canada   and  a  manager  of  a   publicly-traded   reporting   issuer,   having
responsibility for the subject management, advisory and administrative services,
would exercise in comparable circumstances.

Acquisition and Disposition Strategy

The strategy  employed by the Manager is to maintain the level of  production of
oil and natural gas from AOG's existing properties and to supplement  production
by reserve  acquisitions.  To  maintain  production,  capital  expenditures  are
focused  on  development   activity  as  opposed  to  exploration.   Exploration
properties  are  generally  sold,  farmed out or  developed  using  third  party
resources.  Reserve  replacement and additions are achieved through  development
activity and acquisitions.

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

Compensation and Term

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

1.    a fee in an amount equal to 1.5% of Operating Cash Flow, such amount to be
      calculated as at the end of each calendar quarter or portion  thereof,  if
      applicable,  and paid on the 15th day following any such calendar quarter,
      or, if such day is not a Business Day, on the next Business Day; and

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

In addition,  the Manager has the option  (subject to any  necessary  regulatory
approval) of  receiving  all or part of the fee provided in paragraph 2 above in
Trust Units at the Unit Market  Price  calculated  as at the end of the relevant
period. To date, no such election has been made.

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

The Manager does not receive any acquisition or disposition fees.

It is the  intention  of the Manager  that the  management  fees  referred to in
paragraphs 1 and 2 above  (collectively,  the  "Management  Fees") will fund all
employee bonuses and incentive plans and, to date, such fees have been allocated
by the Manager on the following basis:

              Manager Shareholders                       66 2/3%
              Employees of AOG                           33 1/3%

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

The initial term (the "Initial  Term") of the  Management  Agreement is 3 years,
and on each anniversary date of the Management Agreement it automatically renews
on an "evergreen" basis for additional one-year periods, provided that the Board
of Directors  has not provided  notice to the Manager  prior to any such renewal
that such renewal shall not occur. In all instances of termination (except where
the Management  Agreement  terminates at the end of the term), a termination fee
(the  "Initial  Termination  Fee")  equal to the  Management  Fees  paid for the
immediately-prior  two years shall be  payable,  which will be adjusted on a pro
rata

                                       47


basis to reflect a full  two-year  period if a two-year  time period has not yet
passed.  Upon  completion of the Initial  Term, in all instances of  termination
(except where the  Management  Agreement  terminates at the end of the term),  a
termination fee ("Subsequent Termination Fee") equal to the Management Fees paid
for the immediately-prior 2 1/2 years shall be payable. In no instance shall the
Manager be  entitled  to both the  Initial  Termination  Fee and the  Subsequent
Termination Fee. The Initial Termination Fee and the Subsequent  Termination Fee
are, collectively, referred to herein as the "Termination Fees". Notwithstanding
the  foregoing,  if,  during the Initial Term,  Kelly Drader (or an  alternative
individual with  comparable  skill and experience who is acceptable to the Board
of Directors) no longer  provides all or  substantially  all of his work time to
AOG and the Trust,  the  Management  Agreement  can be terminated by AOG and the
Trust and the Manager will not be entitled to any Termination Fees.

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

Conflicts of Interest

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

Pursuant  to the  Management  Agreement,  the  Manager  has agreed to make Kelly
Drader available for the performance of the services to be provided to the Trust
and AOG, and Mr. Drader will, during the Initial Term, commit  substantially all
of his work  time on an  annual  basis to AOG and the  Trust in  performing  the
services to be provided  under the  Management  Agreement and in acting as AOG's
President and Chief Executive Officer.

The  Management  Agreement  also provides that the Manager and the  ManagementCo
Group agree that during the Initial Term:

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

                                  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.

Dependence on AOG

The  Trust is an  open-ended,  limited  purpose  trust  which  will be  entirely
dependent  upon the  operations  and assets of AOG through its  ownership of the
Common Shares, the Notes and the Royalty. Accordingly, the cash distributions to
the Trust  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 the
Trust may be adversely affected.

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  Advantage  has existing  knowledge and expertise or access to
such expertise,  using up-to-date technology to enhance methods, and controlling
costs to maximize  returns.  Advanced  oil and natural gas related  technologies
such  as  three-dimensional  seismography,   reservoir  simulation  studies  and
horizontal  drilling  have been and will be used by  Advantage  to  improve  its
ability to find, develop and produce oil and natural gas.

Operations

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

Continuing  production  from a property,  and, to some extent the  marketing  of
production therefrom,  are largely dependent upon the ability of the operator of
the  property.  To the extent the  operator  fails to  perform  these  functions
properly,  revenue may be  reduced.  Payments  from  production  generally  flow
through  the  operator  and there is a risk of delay and  additional  expense in

                                       51


receiving such revenues if the operator becomes insolvent. Although satisfactory
title reviews are generally  conducted in  accordance  with industry  standards,
such reviews do not guarantee or certify that a defect in the chain of title may
not arise to defeat the claim of AOG to certain  Properties.  A reduction of the
income from the Royalty could result in such circumstances.

Expansion of Operations

The operations and expertise of management of the Trust are currently focused on
conventional  oil and gas  production and  development  in the Western  Canadian
Sedimentary  Basin. In the future,  the Trust may acquire oil and gas properties
outside this  geographic  area. In addition,  the Trust Indenture does not limit
the activities of the Trust to oil and gas production and  development,  and the
Trust 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 future  operational  and  financial
conditions of the Trust being adversely affected.

Oil and Natural Gas Prices

The  monthly  cash  distributions  the  Trust  pays 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 the Trust and
AOG. These factors include, among others:

o     political conditions throughout the world;

o     worldwide economic conditions;

o     weather conditions;

o     the supply and price of foreign oil and natural gas;

o     the level of consumer demand;

o     the price and availability of alternative fuels;

o     the proximity to, and capacity of, transportation facilities;

o     the effect of worldwide energy conservation measures; and

o     government regulations.

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

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

Oil prices were  relatively  high  throughout  2003  averaging  US$31.04  WTI as
compared to and average of US$26.08  WTI in 2002.  The only  quarter in the last
two years that saw  relatively low prices was the first quarter of 2002 when oil
prices averaged US$21.64 WTI.

Monthly AECO prices averaged $6.71/mcf in 2003 as compared to $4.07/mcf in 2002,
an increase of 65%. The AECO gas price was weak throughout the first nine months
of 2002 averaging  $3.67/mcf;  however,  such price increased  significantly  to
$5.26/mcf  in the fourth  quarter.  The monthly AECO price in 2003 ranged from a
high of $10.13/mcf in March to a low of $5.48/mcf in November.  The price of oil
and  natural  gas will  fluctuate  and  price  and  demand  are  factors  beyond
Advantage's  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 Advantage may acquire.  As well, cash  distributions from the Trust will be
highly sensitive to the prevailing price of crude oil and natural gas.

                                       52


Marketing

The  marketability  and price of oil and  natural  gas that may be  acquired  or
discovered by Advantage will be affected by numerous factors beyond  Advantage's
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 the Trust and, as a consequence, the amount
of cash available to distribute to Unitholders.  Therefore, distributions may be
reduced,  or even  eliminated,  at  times  when  significant  capital  or  other
expenditures are made.

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

Assessments of Value of Acquisitions

Acquisitions of resource issuers and resource assets will be based in large part
upon engineering and economic assessments made by independent  engineers.  These
assessments  will  include a series of  assumptions  regarding  such  factors as
recoverability  and  marketability  of oil and gas, future prices of oil and gas
and  operating  costs,  future  capital  expenditures  and  royalties  and other
government levies which will be imposed over the producing life of the reserves.
Many of these factors are subject to change and are beyond the Trust's  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 the Trust uses for its 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 the Trust.  Any such instance may offset the
return on and value of the Trust Units.

Possible Changes in Accounting Standards Applicable to Convertible Debentures

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

Debt Service

AOG has credit facilities in the amount of $180,000,000.  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 the  Trust.  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 the Trust or its
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.

                                       53


Prior Ranking Indebtedness; Absence of Covenant Protection

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

The  Indentures  will not limit the  ability of  Advantage  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 the Trust's  level of  indebtedness,
provides operating investment  guidelines,  mandates the making of distributions
and specify the nature of the Trust's business.

The economic impact on Advantage of claims of aboriginal title is unknown.

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

Environmental Concerns

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

Although AOG  maintains  insurance  coverage  considered  to be customary in the
industry,  it is not fully insured against certain  environmental  risks, either
because such  insurance is not available,  or because of high premium costs.  In
particular,  insurance against risks from environmental pollution occurring over
time   (compared  to  sudden  and   catastrophic   damages)  is  not  available.
Accordingly,  AOG's  properties may be subject to liability due to hazards which
cannot be insured  against,  or have not been insured against due to prohibitive
premium  costs or for  other  reasons.  In such an  event,  these  environmental
obligations  will be funded  out of AOG's cash flow and could  therefore  reduce
distributable income payable to Unitholders.

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

Unforeseen Title Defects

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

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

Delay in Cash Distributions

In addition to the usual delays in payment by  purchasers of oil and natural gas
to the operators of the  Properties,  and by the operator to the Manager or AOG,
payments between any of such parties may also be delayed by restrictions imposed
by lenders, delays in the sale or delivery of products, delays in the connection
of wells to a gathering  system,  blowouts or other  accidents,

                                       54


recovery  by  the  operator  of  expenses  incurred  in  the  operation  of  the
Properties,  or the establishment by the operator of reserves for such expenses.
Any of these delays could adversely affect distributions to Unitholders.

Foreign Currency Exchange Rates and Interest Rates

World oil prices are quoted in United States  dollars and the price  received by
Canadian  producers is therefore affected by the $US/$CAN exchange rate that may
fluctuate  over time. A material  increase in the value of the Canadian  dollar,
which occurred in 2003,  negatively  impacted the Trust's net production revenue
and may  affect  the future  value of the  Trust's  reserves  as  determined  by
independent  evaluations  at this time. The impact is reduced to the extent that
the Trust  has  engaged  in, or in the  future  will  engage in risk  management
activities  related to commodity  prices and foreign  exchange rates.  The Trust
will be subject to unfavourable  price changes and credit risks  associated with
the counterparties  with which it contracts.  The Trust has not entered into any
foreign exchange contracts at this time.

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

Reliance upon the Manager and Senior Executives of AOG

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

Reserves

The value of the Trust Units will depend upon, among other things,  the reserves
attributable  to the  Trust's  properties.  Estimating  reserves  is  inherently
uncertain.  Ultimately,  actual  production,  revenues and  expenditures for the
Trust's  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 the Trust's properties have been  independently  evaluated at the
dates indicated by independent oil and gas reservoir  engineering  firms.  These
firms  consider  a number  of  factors  and  make  assumptions  when  estimating
reserves. These factors and assumptions include:

o     historical  production  in the area compared  with  production  rates from
      similar producing areas;

o     the assumed effect of governmental regulation;

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

o     initial production rates;

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 the Trust's  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.

                                       55


Depletion of Reserves

The Trust has 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 the Trust,  will be  successful in developing or
acquiring  additional  reserves  on  terms  that  meet  the  Trust's  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.  The Trust currently operates properties that represent  approximately
85% of its total daily  production.  To the extent the operator fails to perform
these functions properly or becomes insolvent, revenue may be reduced.

Accounting Write-Downs as a Result of GAAP

Canadian  Generally  Accepted   Accounting   Principles  ("GAAP")  require  that
management  apply  certain  accounting  policies and make certain  estimates and
assumptions  that  affect  reported   amounts  in  the  consolidated   financial
statements of the trust. The accounting  policies may result in non-cash charges
to net income and  write-downs of net assets in the financial  statements.  Such
non-cash  charges and write-downs  may be viewed  unfavourably by the market and
may result in an inability to borrow funds and/or may result in a decline in the
Trust Unit price.

Under  GAAP,  the net  amounts at which  petroleum  and  natural  gas costs on a
property or project basis are carried are subject to a  cost-recovery  test that
is based in part upon  estimated  future  net cash flow  from  reserves.  If net
capitalized costs exceed the estimated  recoverable amounts, the Trust will have
to charge the amounts of the excess to  earnings.  A decline in the net value of
oil and natural gas properties could cause  capitalized costs to exceed the cost
ceiling, resulting in a charge against earnings.

Emerging  GAAP  surrounding  hedge  accounting  may result in  non-cash  charges
against  net income as a result of changes in the fair  market  value of hedging
instruments.  A decrease in the fair market value of the hedging  instruments as
the result of  fluctuations in commodity  prices and foreign  exchange rates may
result in a write-down of net assets and a non-cash  charge  against net income.
Such  write-downs  and  non-cash  charges may be temporary in nature if the fair
market value subsequently increases.

Enforcement of Operating Agreements

Operations  of the wells on  properties  not operated by the Trust 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
the Trust or the  Unitholders.  The  Trust,  as owner of  working  interests  in
properties not operated by it, will generally have a cause of action for damages
arising from a breach of such duty. Although not established by definitive legal
precedent,  it is unlikely  that the Trust or  Unitholders  would be entitled to
bring suit against  third-party  operators to enforce

                                       56


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

Changes in Legislation

There can be no assurance  that the  treatment of mutual fund trusts will not be
changed in a manner adversely  affecting Trust Unitholders.  If the Trust ceases
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 the Trust and its Unitholders.  Tax authorities having jurisdiction over
the Trust or the  Unitholders  may disagree  with how the Trust  calculates  its
income  for  tax  purposes  or  could  change  administrative  practises  to the
detriment of the Trust or the detriment of its Unitholders.

The Trust  expects  that it will  continue to qualify as a mutual fund trust for
purposes of the Tax Act. The Trust 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 the Trust  and its  Unitholders.  Some of the  significant  consequences  of
losing mutual fund trust status are as follows:

o     The  Trust  would be taxed on  certain  types  of  income  distributed  to
      Unitholders,  including  income  generated  by the  royalties  held by the
      Trust.  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     The  Trust  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 its  registration  revoked by the Canada  Customs  and
      Revenue Agency.

In addition,  the Trust may take certain measures in the future to the extent it
believes  necessary  to ensure that the Trust  maintains  its status as a mutual
fund trust.  These measures could be adverse to certain  holders of Trust Units,
particularly  "non-residents"  of Canada as  defined  in the Tax Act.  See "Risk
Factors - Non Resident Ownership of Trust Units".

Investment Eligibility

The Trust 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.

                                       57


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.  The Trust's 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 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
and the ability of the Trust 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  Advantage's  properties can no longer be  economically
produced or  marketed.  Unitholders  will only be able to obtain a return of the
capital  they  invested  during the period  when  reserves  may be  economically
recovered and sold. Accordingly, the distributions received over the life of the
investment may not be equal to or greater than the initial capital investment.

The Trust  Units are not  "deposits"  within the  meaning of the Canada  Deposit
Insurance  Corporation  Act (Canada) and are not insured under the provisions of
that Act or any other legislation. Furthermore, the Trust is not a trust company
and, accordingly, is not registered under any trust and loan company legislation
as it does not carry on or intend to carry on the business of a trust company.

Net Asset Value

The net  asset  value of the  assets  of the  Trust  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
the Trust's assets.

Additional Financing

In the normal course of making  capital  investments  to maintain and expand the
oil and gas  reserves  of the Trust,  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 the Trust  issues  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,  the Trust's
and AOG's  ability to make the  necessary  capital  investments  to  maintain or
expand its 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.

                                       58


Unitholders  have a limited right to require the Trust 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 Trust  Unitholders to liquidate their  investments.  14% Notes or Redemption
Notes which may be distributed in specie to Trust Unitholders in connection with
a redemption will not be listed on any stock exchange and no established  market
is expected to develop for such 14% Notes or Redemption  Notes. Cash redemptions
are subject to limitations.  See "Additional  Information  Respecting  Advantage
Energy Income Fund - Redemption Right".

Non-resident Ownership of Trust Units

In order for the Trust to  maintain  its status as a mutual fund trust under the
Tax Act,  the Trust must not be  established  or  maintained  primarily  for the
benefit of non-residents of Canada  ("non-residents")  within the meaning of the
Tax Act.  The  Board is  proposing  that  certain  changes  be made to the Trust
Indenture to provide that if at any time AOG becomes  aware that the  beneficial
owners  of 45% or  more  of  the  Trust  Units  then  outstanding  are or may be
non-residents or that such a situation is imminent,  AOG, on the Trust's behalf,
shall  review  such  actions  as may be  necessary  to carry  out the  foregoing
intention.

Unitholder Limited Liability

The Trust  Indenture  provides that no Trust  Unitholder  will be subject to any
liability in connection with the Trust or its affairs or obligations and, in the
event that a court  determines  that Trust  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 the Trust's assets.

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

The  operations of the Trust will be 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 on the Trust Unitholders for claims against the Trust.

Future Dilution

An  objective  of the  Trust  is to  continually  add to  its  reserves  through
acquisitions  and through  development,  and because the Trust does not reinvest
its cash flow, the success of the Trust is in part dependent upon its 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

The Trust's  operations are subject to a variety of federal and provincial  laws
and  regulations,  including laws and regulations  relating to the protection of
the environment.

Conflicts of Interest

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

                                       59


respect of such contract or agreement unless otherwise  provided under the ABCA.
To the extent that conflicts of interest arise,  such conflicts will be resolved
in accordance with the provisions of the ABCA.

                             ADDITIONAL INFORMATION

Additional  information,  including  directors' and officers'  remuneration  and
indebtedness,  principal  holders of  securities  and  interests  of insiders in
material  transactions,  where  applicable,  is  contained  in  the  Information
Circular of the Trust dated April 16, 2004.  Additional financial information is

             FINANCIAL STATEMENTS OF MARKWEST RESOURCES CANADA CORP.

November 12, 2003

Auditors' Report

To the Directors of
MarkWest Resources Canada Corp.

We have  audited  the balance  sheet of MarkWest  Resources  Canada  Corp.  (the
"Company")  as at December 31, 2002 and the  statements of earnings and retained
earnings  (deficit)  and cash  flows for the year then  ended.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility is to express an opinion on these financial statements based upon
our audit.

We conducted our audit in accordance with Canadian  generally  accepted auditing
standards.  Those standards  require that we plan and perform an audit to obtain
reasonable  assurance  whether  the  financial  statements  are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management, as well as evaluating the overall financial statement presentation.

In our opinion,  these  financial  statements  present  fairly,  in all material
respects,  the financial position of the Company as at December 31, 2002 and the
results  of its  operations  and its  cash  flows  for the  year  then  ended in
accordance with Canadian generally accepted accounting principles.

1.    Nature of operations

            MarkWest  Resources  Canada Corp. (the  "Company")  explores for and
            produces  oil and natural gas and is a wholly  owned  subsidiary  of
            MarkWest Hydrocarbon, Inc.

2.    Significant accounting policies

            Cash

            Cash  consists  of the  balance  with  the  bank,  cash on hand  and
            short-term  investments with a maturity of three months or less when
            purchased.

            Property, plant and equipment

            The Company  follows the full cost method of accounting  for oil and
            gas  operations,  whereby all costs of exploring for and  developing
            oil and gas properties and related  reserves are  capitalized.  Such
            costs  include  land  acquisition  costs,  costs  of  drilling  both
            productive and non-productive  wells, and geological and geophysical
            expenses and related  overhead.  Proceeds of disposition are applied
            against the cost pools with no gain or loss recognized  except where
            the  disposition  results  in a  significant  change  in the rate of
            depletion.

            The  carrying  value  is  limited  to  the  recoverable   amount  as
            determined  by  estimating  the  future  net  revenues  from  proven
            properties  (based on period  end prices and costs) and the value of
            unproven  properties (at the lower of cost and net realizable value)
            less  estimated   future  site   restoration   costs,   general  and
            administrative expenses and financing costs.

            Capitalized costs,  excluding costs relating to unproven properties,
            are depleted using the unit-of-production  method based on estimated
            proven  reserves of oil and gas before  royalties as  determined  by
            independent  petroleum  engineers.  For  purposes  of the  depletion
            calculation,  oil  and  natural  gas  reserves  and  production  are
            converted to a common unit-of-measure.  Other assets are depreciated
            on a  straight-line  basis over the  estimated  service lives of the
            assets.

            Assets under  capital lease are recorded at the present value of the
            lease payments at the inception of the lease.

            Provision for future site restoration

            The Company  estimates its future site  restoration  and abandonment
            costs  for  its  oil  and  gas   properties.   The  costs  represent
            management's best estimate of the future restoration and abandonment
            costs based upon current  legislation  and industry  practices.  The
            total estimated costs are being provided for on a unit-of-production
            basis. The annual provision is included in amortization  expense and
            actual site restoration  costs are charged to the liability  account
            as incurred.

            Joint ventures

            Certain of the Company's activities are conducted jointly with other
            parties.   These   financial   statements   reflect  the   Company's
            proportionate interest in such activities.

            Financial instruments

            The Company's financial  instruments are comprised of cash, accounts
            receivable,  accounts payable,  advances from parent, long term debt
            and commodity instruments (note 10). The fair value of the financial
            instruments   approximates  their  carrying  amount.  A  significant
            portion of the  Company's  accounts  receivable  is from oil and gas
            companies.   Although  collection  of  these  receivables  could  be
            influenced by economic factors affecting this industry,  the risk of
            significant loss is considered remote.

            Income taxes

            The Company  follows the liability  method of accounting  for income
            taxes.  Under this method,  the Company  records future income taxes
            for the effect of any  differences  between the  accounting  and the
            income  tax basis of an asset or  liability  using  income tax rates
            substantially  enacted on the balance  sheet  date.  The effect of a
            change in income  tax rates on the  future  income  tax  assets  and
            liabilities is recognized in income in the period of the change.

            Measurement uncertainty

            The amount recorded for depletion and depreciation of capital assets
            and the  provision  for future site  restoration  costs are based on
            estimates.  The ceiling  test  calculation  is based on estimates of
            proven reserves,  production rates, oil and gas prices, future costs
            and other relevant assumptions. By their nature, these estimates are
            subject to measurement uncertainty and the effect upon the financial
            statements from changes in such estimates in future periods could be
            significant.

      Costs  for  unproven  properties  of  $45,443,638  at June  30,  2003  and
      $48,420,924  at December 31, 2002 have been  excluded  from the  depletion
      calculation.  During the six month period ended June 30, 2003 and the year
      ended December 31, 2002, the Company capitalized no overhead costs related
      to exploration and development  activities and capitalized  $1,109,482 and
      $2,251,374 of interest expense respectively.

      Month end prices of $29.16/bbl  (December  31, 2002 - $33.49/bbl)  for oil
      and  $6.34/mcf  (December  31,  2002  -$5.66/mcf)  for gas  resulted in no
      ceiling test deficiency at June 30, 2003 or December 31, 2002.

4.    Long-term debt

      On May 24,  2002,  the  Company  amended its credit  agreement  ("Canadian
      Credit  Facility") with various  financial  institutions  for an amount of
      US$35,000,000.  This  facility is a component of the overall debt facility
      of the parent company,  MarkWest Hydrocarbons,  Inc. ("Parent") of Denver,
      Colorado.  The overall amount of the Parent's facility ("Credit Facility")
      is US$60,000,000.

      Available  borrowings  under  the  Credit  Facility  are  determined  by a
      borrowing  base that is determined by the value of the proved  reserves of
      oil  and  gas  owned  by  the  Parent  (directly  or  indirectly   through
      subsidiaries,  including MarkWest Resources Canada Corp.), and also on the
      working  capital of the Parent,  the level of which is  determined  by NGL
      product accounts  receivable and inventory  levels.  The borrowing base on
      proved reserves is calculated  semi-annually,  while the borrowing base on
      working capital is calculated  monthly.  Actual  borrowing  limits for the
      Credit  Facility  may be less  than  US$60,000,000,  depending  on  proved
      reserves, working capital levels, and financial covenants. The Company had
      outstanding borrowings of C$18,000,000, or approximately US$13,320,000, at
      June 30,  2003,  and  C$53,000,000,  or  approximately  US$33,758,000,  at
      December 31, 2002 of the US$35,000,000 available.

      The Canadian Credit Facility  permits  MarkWest  Resources Canada Corp. to
      borrow  money  at a  rate  equal  to the  London  Interbank  Offered  Rate
      ("LIBOR") plus an applicable  margin of between 1.75% and 2.75% based on a
      certain  leverage ratio,  which is determined as the ratio of total funded
      debt to EBITDA. Funds can also be borrowed at the Canadian Prime Rate plus
      an applicable  margin of between 0.375% and 1.375%,  based on the leverage
      ratio.  There  is a fee on the  unused  portion  of  the  Canadian  Credit
      Facility of between  0.25% and 0.50%,  based on the  leverage  ratio.  The
      weighted  average  interest  rate was 5.32% for the period  ended June 30,
      2003, and 5.02% for the year ended December 31, 2002.

      The Credit  Facility is a revolving  facility,  with a maturity and expiry
      date of August 9, 2004. The entire outstanding principal balance is due in
      full on this date. The Credit Facility is  collateralized  by a first lien
      on substantially all the Company's assets.

10.   Commodity instruments

      Derivative  commodity  instruments  may be used  from  time to time by the
      Company to manage its  exposure  to price  risks  relating  to natural gas
      prices.  The  Company's  policy  is to not  utilize  derivative  commodity
      instruments for trading or speculative purposes.

      Realized  gains and losses on  derivative  instruments  used as hedges are
      recognized in income in the period that the hedge is settled.

      The Company had the following natural gas hedge agreements  outstanding at
      June 30, 2003 and December 31, 2002:

       SCHEDULE B - UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

                               COMPILATION REPORT

The Board of Directors of Advantage Oil & Gas Ltd.

We have read the accompanying  unaudited pro forma consolidated balance sheet of
Advantage  Energy Income Fund (the "Fund") as at June 30, 2003 and unaudited pro
forma consolidated statement of operations for the six months then ended and for
the year ended December 31, 2002, and have performed the following procedures:

1.    Compared the figures in the columns captioned "Advantage" to the unaudited
      consolidated  financial statements of the Fund as at June 30, 2003 and for
      the  six  months  then  ended,  and  the  audited  consolidated  financial
      statements of the Fund for the year ended December 31, 2002, respectively,
      and found them to be in agreement.

2.    Compared the figures in the columns captioned  "MarkWest" to the unaudited
      financial  statements  of MarkWest  Resources  Canada Corp. as at June 30,
      2003  and  for the six  months  then  ended,  and  the  audited  financial
      statements of MarkWest  Resources Canada Corp. for the year ended December
      31, 2002, respectively, and found them to be in agreement.

3.    Made  enquiries of certain  officials of the Fund who have  responsibility
      for financial and accounting matters about:

            (a)   The basis for determination of the pro forma adjustments; and

            (b)   Whether the pro forma consolidated financial statements comply
                  as to  form  in all  material  respects  with  the  securities
                  regulations of various provinces.

      The officials:

            (a)   described to us the basis for  determination  of the pro forma
                  adjustments, and

            (b)   stated that the pro forma  consolidated  financial  statements
                  comply as to form in all material respects with the securities
                  regulations of various provinces.

4.    Read the notes to the pro forma  consolidated  financial  statements,  and
      found  them  to  be  consistent   with  the  basis  described  to  us  for
      determination of the pro forma adjustments.

5.    Recalculated the application of the pro forma adjustments to the aggregate
      of the amounts in the columns  captioned  "Advantage" and "MarkWest" as at
      June 30, 2003 and for the six months  then  ended,  and for the year ended
      December  31,  2002,  and found the amounts in the column  captioned  "Pro
      forma" to be arithmetically correct.

A  pro  forma  financial  statement  is  based  on  management  assumptions  and
adjustments  which are  inherently  subjective.  The  foregoing  procedures  are
substantially  less than either an audit or a review,  the objective of which is
the expression of assurance with respect to  management's  assumptions,  the pro
forma  adjustments,  and the  application  of the  adjustments to the historical
financial information.  Accordingly, we express no such assurance. The foregoing
procedures would not necessarily reveal matters of significance to the pro forma
consolidated financial statements, and we therefore make no representation about
the  sufficiency  of the  procedures  for  the  purposes  of a  reader  of  such
statements.

      financial  statements")  have been prepared based on the unaudited balance

ADVANTAGE ENERGY INCOME FUND

Notes to Pro Forma Consolidated Financial Statements

Six months Ended June 30, 2003 and Year Ended December 31, 2002
(unaudited)

      The  above  represents  management's   preliminary  assessment  of  assets
      acquired. The allocation of the purchase price will be finalized after the
      business  combination has been completed and the fair values of the assets
      and liabilities have been determined,  accordingly the above allocation is
      subject to change.  Transaction  costs incurred by Advantage in connection
      with the acquisition include legal,  advisory and other professional costs
      of  $2,000,000  and have been  included  in  accounts  payable and accrued
      liabilities.

      Consideration comprised of:

      Cash                                                         $79,037
      Transaction costs                                              2,000
                                                                   -------
                                                                   $81,037
                                                                   =======

      The acquisition is to be financed through the issuance of $60,000,000 of
      8 1/4% subordinated convertible debentures and the issuance of 5.1 million
      trust units issued at a price of $15.75 per unit. Associated underwriters'
      fees of $2,400,000 are included in  accumulated  income.  Excess  proceeds
      over the purchase price of MarkWest will be used to reduce bank debt.

      (b)   Alberta  Royalty Credit has been reduced to reflect the  requirement
            of   Advantage   to  share  the  maximum   annual   limit  with  its
            subsidiaries.

      (c)   A reduction  of interest  expense  has been  calculated  by applying
            applicable  bank interest rates averaging 5.0% for the period to the
            decrease  in the bank loan with  respect to the  proceeds  raised in
            excess of the purchase price.

      (d)   Depletion,  depreciation  has been adjusted on a consolidated  basis
            incorporating  the fair value of the assets of  MarkWest  determined
            under the purchase method as set out in note 2(a) and  incorporating
            the combined reserves and production.

      (e)   Current  taxes  have  been  adjusted  to  reflect  changes  in large
            corporations tax.

      (f)   Future  income tax expense  has been  adjusted to tax effect the pro
            forma income statement adjustments.

      (g)   Pro forma basic per unit amounts are based on the  weighted  average
            number  of  Advantage  units  outstanding  for the  period  plus the
            additional  units  issued  pursuant  to the  prospectus.  Pro  forma
            diluted per unit amounts are based on the weighted average number of
            diluted   Advantage  units  outstanding  for  the  period  plus  the
            additional  units  that  would be  issued on the  conversion  of the
            convertible debentures referenced under 2(a) and 2(h).

      (h)   Convertible  debentures  and bank debt have been adjusted to reflect
            Advantage's   issuance   of   $30,000,000   of  9.00%   subordinated
            convertible  debentures  on July 8, 2003.  Associated  underwriters'
            fees of $1,200,000 are included in accumulated income.

3.    Convertible Debentures

      The  convertible  debentures and related  interest  obligations  have been
      classified  as  equity  on the  balance  sheet as the  Trust  may elect to
      satisfy the debenture interest and principle obligation by the issuance of
      Trust Units.  Issue costs associated with the debentures have been treated
      as a reduction to retained  earnings.  When calculating cash available for
      distribution  to Unitholders,  interest on the  convertible  debentures is
      deducted from cash flow from operations.
