                        CONSOLIDATED FINANCIAL STATEMENTS


MANAGEMENT'S REPORT

The Management of Advantage Energy Income Fund (the "Fund") is responsible for
the preparation  and  presentation of the  consolidated  financial  statements
together with all operational and other financial information contained in the
annual report.  The financial  statements  have been prepared by Management in
accordance with Canadian generally accepted accounting  principles and utilize
the best  estimates and careful  judgments of Management,  where  appropriate.
Operational and other financial  information  contained  throughout the annual
report  is  consistent  with  that  provided  in  the  consolidated  financial
statements.

Management has developed and maintains a system of internal  controls designed
to provide  reasonable  assurance  that all  transactions  are  accurately and
reliably  recorded,  that the  consolidated  financial  statements  accurately
report the Fund's operating and financial  results within acceptable limits of
materiality, that all other operational and financial information presented is
accurate, and that the Fund's assets are properly safeguarded.

The Audit Committee,  comprised of non-management directors, acts on behalf of
the Board of  Directors  to  ensure  that  Management  fulfils  its  financial
reporting  and  internal  control  responsibilities.  The Audit  Committee  is
responsible for meeting regularly with Management,  the external auditors, and
the internal  auditor to discuss  internal  controls over financial  reporting
processes,  auditing matters and various aspects of financial  reporting.  The
Audit Committee reviewed the consolidated financial statements with Management
and the external auditors, and recommended approval to the Board of Directors.
The Board of Directors has approved these consolidated financial statements.

KPMG LLP, an  independent  firm of  Chartered  Accountants,  appointed  by the
Unitholders as the external  auditor of the Fund, has audited the consolidated
financial  statements in accordance with Canadian  generally accepted auditing
standards.  KPMG LLP have  unlimited  and  unrestricted  access  to the  Audit
Committee.

AUDITORS' REPORT

To the Unitholders of Advantage Energy Income Fund

We have audited the  consolidated  balance  sheets of Advantage  Energy Income
Fund as at  December  31,  2005 and 2004 and the  consolidated  statements  of
income and accumulated  income and cash flows for the years then ended.  These
financial  statements are the  responsibility  of the Fund's  management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We  conducted  our  audits 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 consolidated financial statements present fairly, in all
material respects,  the financial position of the Fund as at December 31, 2005
and 2004 and the  results of its  operations  and its cash flows for the years
then  ended  in  accordance  with  Canadian  generally   accepted   accounting
principles.

December 31, 2005

All tabular amounts in thousands except for Units and per Unit amounts

1.   BUSINESS AND STRUCTURE OF THE FUND

     Advantage  Energy Income Fund  ("Advantage"  or the "Fund") was formed on
     May 23,  2001 as a result  of a plan of  arrangement.  For  Canadian  tax
     purposes,  Advantage is an  open-ended  unincorporated  mutual fund trust
     created  under the laws of the  Province  of Alberta  pursuant to a Trust
     Indenture  originally dated April 17, 2001, and as occasionally  amended,
     between Advantage Oil & Gas Ltd. ("AOG") and Computershare  Trust Company
     of Canada, as trustee. The Fund commenced operations on May 24, 2001. The
     beneficiaries  of the  Fund  are the  holders  of the  Trust  Units  (the
     "Unitholders").

     The principal  undertaking of the Fund is to indirectly  acquire and hold
     interests  in petroleum  and natural gas  properties  and assets  related
     thereto.  The business of the Fund is carried on by its subsidiary,  AOG,
     which is  primarily  owned by the Fund  with a small  residual  interest,
     represented  by the  Exchangeable  Share  ownership held by other parties
     (see note 9). The Fund's  primary  assets are currently the common shares
     of AOG, a royalty in the producing  properties of AOG (the "AOG Royalty")
     and notes of AOG (the "AOG Notes"). The Fund's strategy,  through AOG, is
     to minimize exposure to exploration risk while focusing on growth through
     acquisition  and  development  of  producing  crude oil and  natural  gas
     properties.

     The  purpose  of  the  Fund  is to  distribute  available  cash  flow  to
     Unitholders on a monthly basis in accordance  with the terms of the Trust
     Indenture.  The Fund's available cash flow includes principal  repayments
     and interest income earned from the AOG Notes, royalty income earned from
     the AOG Royalty,  and any dividends  declared on the common shares of AOG
     less  any  expenses  of  the  Fund  including   interest  on  convertible
     debentures. Cash received on the AOG Notes, AOG Royalty and common shares
     of AOG result in the effective  transfer of the economic  interest in the
     properties  of  AOG  to  the  Fund.  However,  while  the  royalty  is  a
     contractual  interest in the properties  owned by AOG, it does not confer
     ownership  in the  underlying  resource  properties.  The  extent of cash
     distributions  from AOG to the Fund are  determined by Management and the
     Board of Directors and are based on the cash available  after retaining a
     portion to meet  expenditure  requirements.  The  distribution  policy is
     closely monitored considering forecasted cash flows, optimal debt levels,
     capital  spending  activity,  working  capital  requirements,  and  other
     potential cash expenditures.  Cash inflows are predominantly dependent on
     the current level of production and the prevailing  commodity  prices. It
     is the Funds long-term  objective to provide stable and sustainable  cash
     distributions to the Unitholders.

     The Fund is actively managed by Advantage Investment Management Ltd. (the
     "Manager").  As  compensation,   the  Manager  receives  management  fees
     pursuant to a Management  Agreement as approved by the Board of Directors
     (see note 13).

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The Management of the Fund prepares its consolidated financial statements
     in accordance with Canadian generally accepted accounting  principles and
     all  amounts  are  stated  in  Canadian   dollars.   The  preparation  of
     consolidated  financial  statements requires Management to make estimates
     and assumptions  that effect the reported  amount of assets,  liabilities
     and  equity  and  disclosures  of   contingencies  at  the  date  of  the
     consolidated  financial  statements and the reported  amounts of revenues
     and expenses  during the period.  The  following  significant  accounting
     policies  are  presented  to  assist  the  reader  in  evaluating   these
     consolidated financial statements and, together with the notes, should be
     considered an integral part of the consolidated financial statements.

     (a) CONSOLIDATION AND JOINT OPERATIONS

     These consolidated  financial statements include the accounts of the Fund
     and all  subsidiaries,  including  AOG.  All  intercompany  balances  and
     transactions have been eliminated.

     The Fund conducts  exploration  and  production  activities  jointly with
     other  participants.  The accounts of the Fund reflect its  proportionate
     interest in such joint operations.


                       Advantage Energy Income Fund - 5


     (b) PROPERTY AND EQUIPMENT

         (i) PETROLEUM AND NATURAL GAS PROPERTIES AND RELATED EQUIPMENT

         The Fund follows the "full cost" method of  accounting  in accordance
         with the  guideline  issued by the  Canadian  Institute  of Chartered
         Accountants   ("CICA")   whereby  all  costs   associated   with  the
         acquisition of and the  exploration  for and development of petroleum
         and natural gas reserves,  whether  productive or  unproductive,  are
         capitalized  in a Canadian  cost  centre and charged to income as set
         out below. Such costs include lease acquisition, drilling, production
         facilities,  asset retirement costs, geological and geophysical costs
         and  overhead   expenses   related  to  exploration  and  development
         activities.

         Gains or losses are not recognized upon  disposition of petroleum and
         natural  gas  properties   unless   crediting  the  proceeds  against
         accumulated  costs would  result in a change in the rate of depletion
         and depreciation of 20% or more.

         Depletion of petroleum and natural gas properties and depreciation of
         lease,  well  equipment  and  production  facilities  is  provided on
         accumulated  costs  using the  "unit-of-production"  method  based on
         estimated  net proved  petroleum  and  natural gas  reserves,  before
         royalties,  as determined by independent  engineers.  For purposes of
         the  depletion and  depreciation  calculation,  proved  petroleum and
         natural gas reserves are converted to a common unit-of-measure on the
         basis of one barrel of oil or  liquids  being  equal to six  thousand
         cubic feet of natural gas.

         The depletion and depreciation  cost base includes total  capitalized
         costs, less costs of unproved properties, plus a provision for future
         development costs of proved undeveloped reserves.  Costs of acquiring
         and  evaluating  unproved  properties  are  excluded  from  depletion
         calculations  until it is determined  whether or not proved  reserves
         are attributable to the properties or impairment occurs.

         Petroleum  and natural  gas assets are  evaluated  in each  reporting
         period to  determine  that the  carrying  amount in a cost  centre is
         recoverable  and does not exceed the fair value of the  properties in
         the cost  centre  (the  "ceiling  test").  The  carrying  amounts are
         assessed to be recoverable  when the sum of the undiscounted net cash
         flows expected from the production of proved  reserves,  the lower of
         cost  and  market  of  unproved  properties  and the  cost  of  major
         development  projects exceeds the carrying amount of the cost centre.
         When the  carrying  amount  is not  assessed  to be  recoverable,  an
         impairment  loss is recognized to the extent that the carrying amount
         of the cost centre  exceeds the sum of the  discounted net cash flows
         expected  from the  production of proved and probable  reserves,  the
         lower of cost and market of unproved properties and the cost of major
         development  projects  of the cost  centre.  The net cash  flows  are
         estimated  using  expected  future  product  prices and costs and are
         discounted using a risk-free interest rate.

         (ii) FURNITURE AND EQUIPMENT

         The  Fund  records  furniture  and  equipment  at cost  and  provides
         depreciation  on the  declining  balance  method at a rate of 20% per
         annum which is designed to amortize the cost of the assets over their
         estimated useful lives.

     (c) GOODWILL

     Goodwill is the excess  purchase  price of a business over the fair value
     of identifiable  assets and liabilities  acquired.  Goodwill is stated at
     cost  less  impairment  and  is not  amortized.  Goodwill  impairment  is
     assessed at year-end,  or as economic  events  dictate,  by comparing the
     fair  value of the  reporting  unit  (the  Fund) to its  carrying  value,
     including  goodwill.  If the  fair  value  of the  Fund is less  than its
     carrying  value, a goodwill  impairment  loss is recognized by allocating
     the fair value of the Fund to the identifiable  assets and liabilities as
     if the Fund had been  acquired in a business  acquisition  for a purchase
     price equal to the fair  value.  The excess of the fair value of the Fund
     over the values  assigned to the  identifiable  assets and liabilities is
     the implied fair value of the goodwill.  Any excess of the carrying value
     of the goodwill over the implied fair value is the impairment  amount and
     is charged to income in the period incurred. There has been no impairment
     of the Fund's goodwill.

     (d) CASH DISTRIBUTIONS

     Cash  distributions  are  calculated  on an accrual basis and are paid to
     Unitholders monthly.

     (e) FINANCIAL INSTRUMENTS

     The  Fund  occasionally  uses  various  types  of  derivative   financial
     instruments  to manage  risk  associated  with crude oil and  natural gas
     price  fluctuations.  These  instruments  are not  used  for  trading  or
     speculative  purposes.  Proceeds  and costs  realized  from  holding  the
     related contracts are recognized in petroleum and natural gas revenues at
     the time that each  transaction  under a  contract  is  settled.  For the
     unrealized portion of such contracts, Advantage utilizes the "fair value"
     method of accounting. The


                       Advantage Energy Income Fund - 6


     fair value is based on an estimate  of the  amounts  that would have been
     paid to or received from counterparties to settle these instruments given
     future market prices and other relevant factors. This method requires the
     fair value of the derivative financial instruments to be recorded at each
     balance  sheet  date.  There  were no  derivative  financial  instruments
     outstanding at December 31, 2005.

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

     The  effect  of this  change  in  accounting  policy  has  been  recorded
     retroactively  with  restatement  of prior  periods.  The  effect  of the
     adoption is presented below as increases (decreases):

     (f) ASSET RETIREMENT OBLIGATIONS

     The Fund follows the "asset retirement obligation" method of recording the
     future cost associated with removal, site restoration and asset retirement
     costs. The fair value of the liability for the Fund's asset retirement
     obligation is recorded in the period in which it is incurred, discounted to
     its present value using the Fund's credit adjusted risk-free interest rate
     and the corresponding amount recognized by increasing the carrying amount
     of property and equipment. The asset recorded is depleted on a
     "unit-of-production" basis over the life of the reserves consistent with
     the Fund's depletion and depreciation policy for petroleum and natural gas
     properties and related equipment. The liability amount is increased each
     reporting period due to the passage of time and the amount of accretion is
     charged to income in the period. Revisions to the estimated timing of cash
     flows or to the original estimated undiscounted cost could also result in
     an increase or decrease to the obligation. Actual costs incurred upon
     settlement of the retirement obligation are charged against the obligation
     to the extent of the liability recorded.


                       Advantage Energy Income Fund - 7


     (g) INCOME TAXES

     The Fund is  considered an  open-ended  unincorporated  mutual fund trust
     under the Income Tax Act (Canada). Any taxable income is allocated to the
     Unitholders  and therefore no provision for current income taxes relating
     to the Fund is included in these financial statements.

     The Fund and its subsidiaries follow the "liability" method of accounting
     for income taxes. Under this method future tax assets and liabilities are
     determined based on differences  between  financial  reporting and income
     tax bases of assets and liabilities, and are measured using substantially
     enacted  tax  rates  and  laws  expected  to apply  when the  differences
     reverse.  The effect on future tax assets and  liabilities of a change in
     tax rates is  recognized  in net income in the period in which the change
     is substantially enacted.

     (h) EXCHANGEABLE SHARES

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

     (i) UNIT-BASED COMPENSATION

     The Fund has a  unit-based  compensation  plan (the  "Plan") for external
     directors of the Fund, which is described in note 10.  Advantage  elected
     to   prospectively   adopt  amendments  to  CICA  Handbook  Section  3870
     "Stock-based Compensation and Other Stock-based Payments" pursuant to the
     transitional  provisions contained therein.  Under this amended standard,
     the Fund must account for compensation  expense based on the "fair value"
     of rights granted under its unit-based compensation plan.

     Since   awards  under  the  Plan  are  vested   immediately,   associated
     compensation  expense is  recognized in the current  period  earnings and
     estimated  forfeiture rates for such rights are not  incorporated  within
     the determination of fair value. The compensation  expense results in the
     creation  of   contributed   surplus  until  the  rights  are  exercised.
     Consideration  paid upon the  exercise  of the rights  together  with the
     amount  previously  recognized in  contributed  surplus is recorded as an
     increase in Unitholders' capital.

     (j) REVENUE RECOGNITION

     Revenue  associated  with the sale of crude oil,  natural gas and natural
     gas liquids is recognized when the title and risks pass to the purchaser,
     normally  at the  pipeline  delivery  point  for  natural  gas and at the
     wellhead for crude oil.

     (k) PER TRUST UNIT AMOUNTS

     Net income per Trust Unit is calculated using the weighted average number
     of Trust Units outstanding  during the year. Diluted net income per Trust
     Unit is  calculated  using the  "if-converted"  method to  determine  the
     dilutive effect of convertible debentures and exchangeable shares and the
     "treasury stock" method for trust unit rights.

     (l) MEASUREMENT UNCERTAINTY

     The amounts  recorded  for  depletion  and  depreciation  of property and
     equipment,  the  provision  for  asset  retirement  obligation  costs and
     related accretion expense,  and impairment  calculations for property and
     equipment  and  goodwill  are based on  estimates.  These  estimates  are
     significant and include proved and probable  reserves,  future production
     rates,  future  crude oil and natural gas prices,  future  costs,  future
     interest  rates,  relevant  fair value  assessments,  and other  relevant
     assumptions.  By their nature, these estimates are subject to measurement
     uncertainty and the effect on the  consolidated  financial  statements of
     changes in such estimates in future years could be material.

     Certain  comparative  figures  have been  reclassified  to conform to the
     current year's presentation.

3.   ACQUISITIONS

     (a) DEFIANT ENERGY CORPORATION

     On December 21, 2004 Advantage acquired all of the issued and outstanding
     shares of Defiant Energy  Corporation  ("Defiant") for  consideration  of
     $143.1 million. Defiant was a corporation engaged in the exploration for,
     and the development, acquisition and production of, natural gas and crude
     oil in  western  Canada.  The  acquisition  was  accounted  for using the
     "purchase  method"  with  the  results  of  operations  included  in  the
     consolidated   financial  statements  as  of  the  closing  date  of  the
     acquisition.  Defiant was  amalgamated  with AOG on January 1, 2005.  The
     purchase price has been allocated as follows:



     Net assets acquired and liabilities assumed:            Consideration:

                                                                                                   ------------
     Net working capital

                                            -----------
                                           $   143,088


     The value of the Trust Units and  Exchangeable  Shares  issued as partial
     consideration  was determined based on the weighted average trading value
     of Advantage  Trust Units during the two-day  period before and after the
     terms of the acquisition were agreed to and announced.  The allocation of
     the purchase  price has been revised in 2005 due to the  finalization  of
     net working capital acquired, tax balances and certain cost estimates. As
     a result,  net working  capital  deficit  increased $1.2 million,  future
     income tax liability  decreased  $1.9 million,  goodwill  decreased  $1.8
     million and acquisition costs decreased $1.1 million.

     (b) ASSET ACQUISITION

     On  September  15,  2004  Advantage  closed  the  acquisition  of certain
     petroleum  and  natural  gas   properties  and  related  assets  for  net
     consideration of $179.1 million. The asset retirement  obligation assumed
     and recorded on this acquisition was $6.6 million.

4.   FIXED ASSETS

     During the year ended December 31, 2005,  Advantage  capitalized  general
     and  administrative  expenditures  directly  related to  exploration  and
     development  activities  of  $3,293,000  (2004 -  $2,401,000).

     Costs of $17,805,000  (2004 - $25,700,000)  for unproved  properties have
     been  excluded  from the  calculation  of depletion  expense,  and future
     development costs of $ 87,843,000 (2004 - $64,200,000) have been included
     in costs subject to depletion.

     The Fund  performed a ceiling  test  calculation  at December 31, 2005 to
     assess the  recoverable  value of property  and  equipment.  Based on the
     calculation,  the carrying amounts are recoverable as compared to the sum
     of the undiscounted net cash flows expected from the production of proved
     reserves based on the following benchmark prices:

     Benchmark  prices are  adjusted  for a variety of factors such as quality
     differentials  to determine the expected price to be realized by the Fund
     when performing the ceiling test calculation.

5.   CAPITAL LEASE OBLIGATIONS

     The Fund has  capital  leases on a variety  of  property  and  equipment.
     Future  minimum  lease  payments  at  December  31,  2005  consist of the
     following:

6.   BANK INDEBTEDNESS

     Advantage has a credit  facility  agreement  with a syndicate of Canadian
     chartered  banks which provides for a $345 million  extendible  revolving
     loan  facility  and a $10 million  operating  loan  facility.  The loan's
     interest  rate is based on either prime or bankers'  acceptance  rates at
     the  Fund's  option  subject  to  certain  basis  point or  stamping  fee
     adjustments  ranging  from 0.85% to 1.4%  depending on the Fund's debt to
     cash flow ratio.  The credit  facilities  are  secured by a $500  million
     floating  charge demand  debenture,  a general  security  agreement and a
     subordination agreement from the Fund covering all assets and cash flows.
     The credit  facilities are subject to review on an annual basis, with the
     next  review  anticipated  to take place in May 2006.  Various  borrowing
     options  are  available  under the  credit  facilities,  including  prime
     rate-based advances and bankers' acceptances loans. The credit facilities
     constitute a revolving  facility  for a 364 day term which is  extendible
     annually  for a further  364 day  revolving  period at the  option of the
     syndicate. If not extended, the revolving credit facility is converted to
     a two year term  facility with the first payment due one year and one day
     after  commencement of the term. The credit  facilities  contain standard
     commercial  covenants for facilities of this nature, and distributions by
     AOG to  the  Fund  (and  effectively  by the  Fund  to  Unitholders)  are
     subordinated  to the  repayment  of any  amounts  owing  under the credit
     facilities. Distributions to Unitholders are not permitted if the Fund is
     in  default  of such  credit  facilities  or if the  amount of the Fund's
     outstanding  indebtedness under such facilities exceeds the then existing
     current  borrowing base.  Interest payments under the debentures are also
     subordinated  to  indebtedness  under the credit  facilities and payments
     under the debentures are similarly restricted.  At December 31, 2005, the
     effective interest rate on the outstanding amounts under the facility was
     approximately 4.4%.


7.   CONVERTIBLE DEBENTURES

     The   convertible   unsecured   subordinated   debentures   pay  interest
     semi-annually  and are convertible at the option of the holder into Trust
     Units of Advantage at the applicable conversion price per Trust Unit plus
     accrued and unpaid interest.  Based on revised accounting  standards (see
     note 2),  Advantage  initially  records the  proceeds as a liability  and
     equity component, net of issue costs, based on their relative fair market
     values. The details of the convertible  debentures  including fair market
     values initially assigned and issuance costs are as follows:



                                   10.00%           9.00%          8.25%            7.75%           7.50%        TOTAL

8.   ASSET RETIREMENT OBLIGATIONS

     The  Fund's  asset  retirement  obligations  result  from  net  ownership
     interests  in  petroleum  and  natural gas assets  including  well sites,
     gathering systems and processing facilities. The Fund estimates the total
     undiscounted and inflated amount of cash flows

     required to settle its asset retirement  obligations is approximately $94
     million  which will be incurred  between 2006 to 2056. A  credit-adjusted
     risk-free  rate of 7% was used to  calculate  the fair value of the asset
     retirement   obligations.

     A reconciliation of the asset retirement obligations is provided below:

     AOG is authorized to issue an unlimited number of non-voting Exchangeable
     Shares.  As partial  consideration  for the  acquisition of Defiant which
     closed on December 21, 2004, AOG issued  1,450,030  Exchangeable  Shares.
     The value of the  Exchangeable  Shares issued was determined based on the
     weighted  average  trading  value of  Advantage  Trust  Units  during the
     two-day period before and after the terms of the acquisition  were agreed
     to and announced.  Each Exchangeable  Share issued by AOG is exchangeable
     for Advantage  Trust Units at any time (subject to the  provisions of the
     Voting and  Exchange  Trust  Agreement),  on the basis of the  applicable
     exchange  ratio in effect at that time.  The exchange  ratio was equal to
     1.16949 at December  31, 2005 and will be  increased  on each date that a
     distribution  is paid by  Advantage  on the  Advantage  Trust Units by an
     amount  equal to the  cash  distribution  paid  divided  by the  five-day
     weighted  average  unit  price  preceding  the  record  date.  It is  not
     anticipated  that dividends will be declared or paid on the  Exchangeable
     Shares. The Exchangeable Shares are not publicly traded. However, holders
     of AOG  Exchangeable  Shares  can  exchange  all or a  portion  of  their
     holdings  at any time by giving  notice to their  investment  advisor  or
     AOG's transfer agent, Computershare Trust Company of Canada.

     The  Exchangeable  Shares will not be entitled to any vote at meetings of
     shareholders of AOG but will,  through a Special Voting Unit of Advantage
     held by the  Trustee as  trustee  under the  Voting  and  Exchange  Trust
     Agreement, be entitled to vote (on the basis of the number of votes equal
     to the number of Advantage Trust Units into which the Exchangeable Shares
     are then  exchangeable)  with the holders of  Advantage  Trust Units as a
     class.  The  Exchangeable  Shares will be  redeemable  by AOG, in certain
     circumstances, and will be retractable by holders of Exchangeable Shares,
     in certain circumstances.

     Exchangeable Shares not previously redeemed or retracted will be redeemed
     by AOG or purchased  by  Advantage on January 15, 2008.  If the number of
     Exchangeable Shares outstanding is less than 100,000,  the Fund can elect
     to redeem the  Exchangeable  Shares for Trust  Units or an amount in cash
     equal to the amount  determined by multiplying  the exchange ratio on the
     last  business  day prior to the  redemption  date by the current  market
     price of a Trust Unit on the last  business day prior to such  redemption
     date.

     (b) TRUST UNITS RIGHTS INCENTIVE PLAN

     Effective June 25, 2002, a Trust Units Rights Incentive Plan for external
     directors of the Fund was  established and approved by the Unitholders of
     Advantage. A total of 500,000 Trust Units have been reserved for issuance
     under the plan with an aggregate of 400,000 rights  granted.  The initial
     exercise  price of rights granted under the plan may not be less than the
     current  market  price of the Trust Units as of the date of the grant and
     the maximum term of each right is not to exceed ten years with all rights
     vesting  immediately upon grant. At the option of the rights holder,  the
     exercise  price of the rights can be adjusted  downwards  over time based
     upon distributions paid by the Fund to Unitholders.

     On June 17, 2004,  the Fund issued  225,000 Series B Trust Unit rights to
     the independent directors of Advantage at a price of $18.42 per right and
     recorded a non-cash  unit-based  compensation  expense of $1.0 million to
     recognize  the fair  value of the rights  granted.  The fair value of the
     Trust Unit rights was  determined  using the  Black-Scholes-Merton  model
     which  included the following  assumptions:  4% risk-free  interest rate,
     approximate  4 year  expected  life,  15%  expected  volatility,  and 15%
     expected  dividend yield. As the rights vested  immediately and are fully
     exercisable,  no further expense will be recognized related to the rights
     issuance.  No Trust  Unit  rights  were  issued  in 2005 and there was no
     compensation expense recorded.

     The  Series A Trust  Unit  rights  were  issued  in 2002 and the Fund was
     unable to determine the fair value for the rights  granted under the Plan
     at that time.  Several  essential  factors  required to value such rights
     include   expected  future  exercise   price,   distributions,   exercise
     timeframe,  volatility and risk-free interest rates. In determining these
     assumptions, both historical data and future expectations are considered.
     However,  when the Series A Trust Unit  rights were  originally  granted,
     Advantage had only been  established  during the prior year and there was
     little   historical   information   available  that  may  suggest  future
     expectations  concerning such  assumptions.  Therefore,  it was concluded
     that a fair value  determination at that time was not possible.  The Fund
     has  disclosed  pro forma  results as if the Fund  followed the intrinsic
     value  methodology  in accounting  for such rights.  The intrinsic  value
     methodology would result in recording compensation expense for the rights
     based on the  underlying  Trust Unit price at the date of  exercise or at
     the date of the financial  statements for unexercised  rights as compared
     to the exercise price.

     The  calculation of diluted net income per Trust Unit excludes all series
     of  convertible  debentures as the impact would be  anti-dilutive.  Total
     weighted  average  Trust Units  issuable in exchange for the  convertible
     debentures  and  excluded  from the  diluted  net  income  per Trust Unit
     calculation  for the year ended  December 31, 2005 was 7,288,894  (2004 -
     5,970,897).  As at December 31, 2005,  the total  convertible  debentures
     outstanding  were  immediately   convertible  to  6,818,833  Trust  Units
     (December 31, 2004 - 7,602,487).


11.  INCOME TAXES

     The taxable income of the Fund is comprised of interest income related to
     the AOG Notes and royalty income from the AOG Royalty less deductions for
     Canadian  Oil and Gas  Property  Expense,  Trust  Unit issue  costs,  and
     interest on convertible debentures. Given that taxable income of the Fund
     is allocated to the  Unitholders,  no provision for current  income taxes
     relating  to the Fund is included in these  financial  statements.  As at
     December  31,  2005,  the  Fund  had  unrecognized  deductible  temporary
     differences of $19.6 million.

     The  provision  for income  taxes  varies  from the amount  that would be
     computed by applying the combined  Canadian federal and provincial income
     tax rates for the following reasons:

- ------------------------------------------------------------------------------------


     AOG has non-capital tax loss carry forward of approximately $33.0 million
     of which $0.3 million  expires in 2007,  $20.7 million in 2009, and $12.0
     million in 2014.

12.  FINANCIAL INSTRUMENTS

     Financial instruments of the Fund include accounts receivable,  deposits,
     accounts payable and accrued  liabilities,  cash  distributions  payable,
     capital  lease  obligations,  and bank  indebtedness.  As at December 31,
     2005, there were no significant  differences between the carrying amounts
     reported  on the  balance  sheet and the  estimated  fair values of these
     financial instruments due to the short terms to maturity and the floating
     interest rate on the bank debt.  Substantially all of the Fund's accounts
     receivable are due from  customers and joint venture  partners in the oil
     and gas industry and are subject to normal industry credit risks.  Credit
     risk is  mitigated  by entering  into sales  contracts  with only stable,
     creditworthy  parties  and  through  frequent  reviews  of  exposures  to
     individual  entities.  The carrying value of accounts receivable reflects
     Management's  assessment  of the  associated  credit  risks.  The Fund is
     further  exposed to interest rate risk to the extent that bank debt is at
     a floating rate of interest.

     In addition,  the Fund has outstanding  convertible debenture obligations
     that are financial liabilities. The convertible debentures have different
     fixed terms and interest rates (see note 7) resulting in fair values that
     will vary over time as market conditions change. As at December 31, 2005,
     the estimated fair value of the total outstanding  convertible  debenture
     obligation was $137.5 million.


13.  MANAGEMENT FEE AND PERFORMANCE INCENTIVE FEE

     The Manager  receives both a management  fee and a performance  incentive
     fee as compensation  pursuant to a Management  Agreement  approved by the
     Board  of  Directors.  Management  fees are  calculated  based on 1.5% of
     operating  cash flow which is  defined as  revenues  less  royalties  and
     operating costs.  Management fees are paid quarterly and $1.0 million was
     payable at December 31, 2005 (December 31, 2004 - $0.7 million).

     The Manager of the Fund is also  entitled  to earn an annual  performance
     incentive fee when the Fund's total annual  return  exceeds 8%. The total
     annual  return  is  calculated  at the end of the  year by  dividing  the
     year-over-year  change  in Unit  price  plus  cash  distributions  by the
     opening  Unit price,  as defined in the  Management  Agreement.  The 2005
     opening  and closing  Unit  prices  were $21.71 and $22.19,  respectively
     (2004   opening  and   closing   Unit  prices  were  $17.83  and  $21.71,
     respectively).  Cash  distributions  for the year  amounted  to $3.12 per
     Trust Unit  (2004 cash  distributions  were  $2.82 per Trust  Unit).  Ten
     percent  of the  amount  of the  total  annual  return in excess of 8% is
     multiplied  by the market  capitalization  (defined as the  opening  Unit
     price   multiplied  by  the  weighted   average  number  of  Trust  Units
     outstanding during the year) to determine the performance  incentive fee.
     The  performance  incentive  fee  payable  at year end for 2005 was $10.5
     million (2004 - $21.6  million).  The  Management  Agreement  provides an
     option  to the  Manager  to  receive  the  performance  incentive  fee in
     equivalent Trust Units.  The Manager  exercised the option and on January
     20, 2006,  the Fund issued 475,263  Advantage  Trust Units at the closing
     Unit price of $22.19 to  satisfy  the  performance  fee  obligation.  The
     Manager  does  not  receive  any  form  of  compensation  in  respect  of
     acquisition  or  divestiture  activities  nor is there  any form of stock
     option  or bonus  plan for the  Manager  or the  employees  of  Advantage
     outside of the management and  performance  fees. The management fees and
     performance fees are shared amongst all management and employees.

14.  LEASE COMMITMENTS

     Advantage  has  lease  commitments  relating  to  office  buildings.  The
     estimated  annual  minimum   operating  lease  rental  payments  for  the
     buildings, after deducting sublease income, are as follows:

         2006                                       $ 1,430

15.  RECONCILIATION  OF  FINANCIAL   STATEMENTS  TO  UNITED  STATES  GENERALLY
     ACCEPTED ACCOUNTING PRINCIPLES

     The consolidated  financial statements of Advantage have been prepared in
     accordance  with  accounting  principles  generally  accepted  in  Canada
     ("Canadian GAAP"). Canadian GAAP, in most respects, conforms to generally
     accepted  accounting  principles  in the United  States ("US GAAP").  Any
     differences in accounting  principles  between Canadian GAAP and US GAAP,
     as they apply to Advantage, are not material,  except as described below.
     All adjustments are measurement differences only and disclosure items are
     not noted.

     (a) UNIT-BASED COMPENSATION

     Effective January 1, 2003, the Fund  prospectively  adopted amendments to
     CICA 3870  "Stock-based  Compensation  and Other  Stock-based  Payments".
     Under this  amended  standard,  the Fund must  account  for  compensation
     expense based on the fair value of rights  granted  under its  unit-based
     compensation  plan.  Under US GAAP, the Fund  similarly  adopted SFAS 123
     "Accounting  for  Stock-Based   Compensation"  and  applied   prospective
     transitional  provisions  of SFAS 148 relative to grants after January 1,
     2003.  As a  result,  both  Canadian  GAAP and US GAAP are  substantially
     similar  with regards to  accounting  for such  stock-based  compensation
     arrangements  and there are no  accounting  differences  for grants after
     January 1, 2003.

     For grants prior to January 1, 2003, no compensation  cost was recognized
     at the grant date given that the options were issued at market value.  As
     options are  subsequently  exercised  under the  unit-based  compensation
     plan, the  consideration  received is recorded as  unitholders'  capital.
     However,  the  Fund  does  calculate  compensation  expense  based on the
     intrinsic  value of the  rights  which is  disclosed  in the notes to the
     consolidated financial statements along with the associated impact on net
     income and net income per Trust Unit.  Intrinsic  value is  calculated as
     the  difference  between the quoted market price and the exercise  price.
     Under US GAAP,  as the Trust Units  Rights  Incentive  Plan is a variable
     compensation  plan,  grants  prior to  January  1,  2003  continue  to be
     accounted  for in accordance  with  Accounting  Principles  Board ("APB")
     Opinion No. 25, whereby  compensation  expense is actually  recorded each
     period-end  using  the  intrinsic  value   methodology.   This  different
     accounting treatment has resulted in additional  unit-based  compensation
     expense for the Fund related to options granted during 2002.

     (b) CONVERTIBLE DEBENTURES

     The Fund applies CICA 3860  "Financial  Instruments  -  Presentation  and
     Disclosure" in accounting  for  convertible  debentures  which results in
     their classification as long-term liabilities. The convertible debentures
     also have an embedded conversion feature which must be segregated between
     liabilities  and equity,  based on the relative  fair market value of the
     liability and equity portions.  Therefore,  the debenture liabilities are
     presented at less than their eventual maturity values.  The liability and
     equity  components  are further  reduced  for  issuance  costs  initially
     incurred. The discount of the liability component, net of issuance costs,
     as  compared to maturity  value is  accreted  by the  effective  interest
     method over the  debenture  term.  As  debentures  are converted to Trust
     Units, an appropriate  portion of the liability and equity components are
     transferred to unitholders'  capital.  Interest and accretion  expense on
     the convertible  debentures are shown on the  Consolidated  Statements of
     Income.

     Under US GAAP, the entire convertible debenture balance would be shown as
     a long-term  liability.  The  embedded  conversion  feature  would not be
     accounted for separately as a component of equity. Additionally, under US
     GAAP, issuance costs are generally shown as a deferred charge rather than
     netted from the convertible  debenture  balance.  As a result of these US
     GAAP  differences,   the  convertible   debenture  balance  in  long-term
     liabilities  represents  the  actual  maturity  value of the  outstanding
     debentures.  Issuance costs are shown separately as a deferred charge and
     are amortized to interest  expense over the term of the debenture.  Given
     that the convertible  debentures are carried at maturity value, it is not
     necessary  to accrete the balance over the term of the  debentures  which
     results in an expense  reduction.  Interest and accretion on  convertible
     debentures represents interest expense on the convertible  debentures and
     amortization of the associated deferred issuance costs.


                       Advantage Energy Income Fund - 17


     (c) DEPLETION AND DEPRECIATION

     For Canadian GAAP,  depletion of petroleum and natural gas properties and
     depreciation of lease and well equipment is provided on accumulated costs
     using  the  unit-of-production  method  based  on  estimated  net  proved
     petroleum and natural gas reserves,  before royalties,  based on forecast
     prices and costs.

     US  GAAP  provides  for a  similar  accounting  methodology  except  that
     estimated  net proved  petroleum  and  natural  gas  reserves  are net of
     royalties and based on constant  prices and costs.  Therefore,  depletion
     and depreciation under US GAAP will be different since changes to royalty
     rates will impact both proved  reserves and  production  and  differences
     between  constant  prices and costs as compared  to  forecast  prices and
     costs will impact proved reserve  volumes.  Additionally,  differences in
     depletion  and  depreciation  will result in divergence of net book value
     for  Canadian  GAAP  and US GAAP  from  year-to-year  and  impact  future
     depletion and depreciation expense as well as the net book value utilized
     for future ceiling test calculations.

     (d) CEILING TEST

     Under Canadian GAAP,  petroleum and natural gas assets are evaluated each
     reporting period to determine that the carrying amount is recoverable and
     does not exceed the fair value of the  properties in the cost centre (the
     "ceiling test"). The carrying amounts are assessed to be recoverable when
     the sum of the  undiscounted  net cash flows expected from the production
     of proved reserves,  the lower of cost and market of unproved  properties
     and the cost of major development projects exceeds the carrying amount of
     the  cost  centre.  When  the  carrying  amount  is  not  assessed  to be
     recoverable,  an  impairment  loss is  recognized  to the extent that the
     carrying  amount of the cost centre exceeds the sum of the discounted net
     cash flows expected from the production of proved and probable  reserves,
     the lower of cost and market of unproved properties and the cost of major
     development  projects of the cost  centre.  The cash flows are  estimated
     using expected future product prices and costs and are discounted using a
     risk-free  interest rate.  For Canadian GAAP purposes,  Advantage has not
     recognized an impairment loss since inception.

     Under US GAAP, the carrying  amounts of petroleum and natural gas assets,
     net of deferred income taxes, shall not exceed an amount equal to the sum
     of the present  value of  estimated  net future  after-tax  cash flows of
     proved  reserves  (at current  prices and costs as of the  balance  sheet
     date) computed  using a discount  factor of ten percent plus the lower of
     cost or  estimated  fair  value of  unproved  properties.  Any  excess is
     charged  to  expense  as an  impairment  loss.  Under US GAAP,  Advantage
     recognized an impairment loss of $49.5 million in 2001, $28.3 million net
     of tax.  The  impairment  loss  decreased  net book value of property and
     equipment which reduced depletion and depreciation  expense  subsequently
     recorded as well as future ceiling test calculations.

     (e) FUTURE INCOME TAX

     The  future  income  tax  accounting  standard  under  Canadian  GAAP  is
     substantially  similar to the deferred income tax approach as required by
     US GAAP. Pursuant to Canadian GAAP,  substantively  enacted tax rates are
     used to calculate  future income tax, whereas US GAAP applies enacted tax
     rates.  However,  there were no tax rate  differences for the years ended
     December 31, 2005 and 2004. The differences  between Canadian GAAP and US
     GAAP relate to future income tax impact on GAAP differences for depletion
     and depreciation, and impairments from ceiling test calculations.

     (f) NON-CONTROLLING INTEREST

     The Fund owns a significant  majority of AOG and  consolidates the entire
     entity. As a result,  non-controlling interest expense is presented which
     represents the residual ownership interests. Accounting standards for the
     determination  of   non-controlling   interest  under  Canadian  GAAP  is
     substantially  similar as compared to US GAAP.  The  differences  between
     Canadian  GAAP  and US  GAAP  non-controlling  interest  expense  relates
     entirely  to  the  non-controlling  interests  share  of all  other  GAAP
     difference that have impacted net income.

     (g) UNITHOLDERS' EQUITY

     Unitholders'  equity of Advantage  consists primarily of Trust Units. The
     Trust Units are redeemable at any time on demand by the holders, which is
     required  for the Fund to retain its Canadian  mutual fund trust  status.
     The holders  are  entitled to receive a price per Trust Unit equal to the
     lesser of: (i) 85% of the simple  average of the closing market prices 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;  and (ii) the closing market price on the principal market on
     which the Trust Units are quoted for trading on the redemption  date. For
     Canadian GAAP purposes,  the Trust Units are considered  permanent equity
     and are presented as a component of unitholders' equity.


                       Advantage Energy Income Fund - 18


     Under US GAAP, it is required that equity with a redemption feature be
     presented as temporary equity between the liability and equity sections of
     the balance sheet. The temporary equity is shown at an amount equal to the
     redemption value based on the terms of the Trust Units. The same accounting
     treatment would be applicable to the Exchangeable Shares. Changes in the
     redemption value from year-to-year are charged to deficit. All components
     of unitholders' equity related to Trust Units and Exchangeable Shares are
     eliminated. When calculating net income per Trust Unit, increases in the
     redemption value during a period results in a reduction of net income
     available to Unitholders while decreases in the redemption value increases
     net income available to Unitholders. For the years ended December 31, 2005
     and 2004, net income available to Unitholders was increased by $3.7 million
     and reduced by $104.4 million corresponding to changes in the Trust Units
     redemption value for the respective periods.

     (h) COMPREHENSIVE INCOME

     US GAAP requires the presentation of net income and comprehensive income.
     Comprehensive  income includes net income plus other comprehensive income
     items as  specifically  identified by US GAAP.  The Fund currently has no
     financial  items  that  qualify  as  other   comprehensive   income,  and
     therefore, net income and comprehensive income are equivalent.

     (i) STATEMENTS OF CASH FLOW

     The  differences  between  Canadian GAAP and US GAAP have not resulted in
     any  significant  variances  concerning  the  statements of cash flows as
     reported.

     (j) RECENT US ACCOUNTING PRONOUNCEMENTS ISSUED BUT NOT IMPLEMENTED

     SFAS 123R  SHARE-BASED  PAYMENT:  SFAS 123R was issued December 2004 as a
     revision to SFAS 123. This statement establishes accounting standards for
     transactions in which an entity exchanges equity instruments for goods or
     services.  The standard also  addresses  transactions  in which an entity
     incurs  liabilities  in exchange for goods or services  that are based on
     the fair value of the entity's equity  instruments or that may be settled
     by the issuance of equity  instruments.  This statement focuses primarily
     on  accounting  for  transactions  in which an  entity  obtains  employee
     services  in  share-based   payment   transactions.   The  implementation
     effective  date for this  standard  is as of the  beginning  of the first
     interim or annual  reporting  period that begins after June 15, 2005. The
     Fund has not yet assessed the full  impact,  if any, of this  standard on
     the consolidated financial statements.

     SFAS 153  EXCHANGES OF  NONMONETARY  ASSETS:  This  statement  amends APB
     Opinion No. 29, Accounting for Nonmonetary Transactions.  APB Opinion No.
     29 is based on the principle that exchanges of nonmonetary  assets should
     be measured based on the fair value of the assets  exchanged with certain
     exceptions  to  that  basic  principle.  This  statement  eliminates  the
     exception  for  nonmonetary  exchanges of similar  productive  assets and
     replaces it with a general exception for exchanges of nonmonetary  assets
     that  do not  have  commercial  substance.  A  nonmonetary  exchange  has
     commercial  substance if the future cash flows of the entity are expected
     to change  significantly as a result of the exchange.  The implementation
     effective date for this standard is for nonmonetary  exchanges  occurring
     in fiscal periods beginning after June 15, 2005. The Fund does not expect
     this statement to have a material  impact on the  consolidated  financial
     statements.

     SFAS 154 ACCOUNTING CHANGES AND ERROR CORRECTIONS: This statement applies
     to all voluntary changes in accounting  principle and changes required by
     an   accounting   pronouncement   in  the  unusual   instance   that  the
     pronouncement  does not include specific  transition  provisions.  When a
     pronouncement includes specific transition  provisions,  those provisions
     should be followed.  This statement  replaces prior accounting  standards
     that  required  most  voluntary   changes  in  accounting   principle  be
     recognized  by  including  in net  income of the period of the change the
     cumulative  effect of  changing  to the new  accounting  principle.  This
     statement requires retrospective  application to prior periods' financial
     statements of changes in accounting  principle (with certain  exceptions)
     as if  that  principle  had  always  been  used or as the  adjustment  of
     previously  issued  financial  statements  to  reflect  a  change  in the
     reporting  entity.  When it is  impracticable  to  determine  the  period
     specific effects of an accounting  change on one or more individual prior
     periods  presented,  this  statement  requires  that  the new  accounting
     principle be applied to the balances of assets and  liabilities as of the
     beginning of the earliest period for which  retrospective  application is
     practicable  and that a  corresponding  adjustment be made to the opening
     balance of retained earnings (or other  appropriate  components of equity
     or net assets in the  statement  of financial  position)  for that period
     rather  than  being  reported  in  an  income   statement.   When  it  is
     impracticable to determine the cumulative  effect of applying a change in
     accounting  principle to all prior periods,  this statement requires that
     the  new   accounting   principle  be  applied  as  if  it  were  adopted
     prospectively  from the earliest  date  practicable.  The  implementation
     effective  date  for  this  standard  is  for   accounting   changes  and
     corrections of errors made in fiscal years  beginning  after December 15,
     2005.  The  impact  of  this  standard  on  the  consolidated   financial
     statements  will be dependent on the nature and extent of subsequent  new
     and revised accounting pronouncements.
