CASH DISTRIBUTIONS TO UNITHOLDERS

o     The Fund declared three distributions during the quarter totalling $0.69
      per Unit. The distributions amounted to $0.23 per Unit, payable on
      February 17, March 15 and April 15 to Unitholders of record on January 30,
      February 27 and March 31 respectively.

o     Cash available for distribution for the first quarter was $29.9 million or
      $0.79 per Unit compared to the amount reported in Q1 2003 of $0.84 per
      Unit and represents a payout ratio of 88% of total cash available for
      distribution.

OIL & NATURAL GAS PRODUCTION

o     Production volumes increased by 28% to 15,449 boe/d in the first quarter
      of 2004 from 12,029 boe/d in the first quarter of 2003.

NATURAL GAS

o     Natural gas production for the first quarter of 2004 was 75.6 mmcf/d, a
      39% increase over the 54.5 mmcf/d reported in the first quarter of 2003.

o     The acquisition of MarkWest Resources, which closed December 2, 2003,
      added approximately 20 mmcf/d of new natural gas production in the first
      quarter of 2004.

o     During the first quarter of 2004 Advantage drilled 34.4 net (38 gross)
      wells resulting in 30.5 net (32 gross) natural gas wells, 1 net (1 gross)
      dry hole and 2.9 net (5 gross) untested wells.

CRUDE OIL & NGLS

o     Crude oil and natural gas liquids production averaged 2,841 bbls/d
      compared to 2,946 bbls/d in the first quarter of 2003 representing a
      decline of 4%. First quarter 2003 oil production included 240 bbls/d
      related to a minor property disposition that occurred in the fourth
      quarter of 2003.

o     The acquisition of MarkWest Resources partially offset this decline adding
      461 bbls/d of oil and NGL production in Q1 2004.

o     During the first quarter the Fund drilled 3.7 net (6 gross) successful oil
      wells.

DEVELOPMENT ACTIVITY

MEDICINE HAT

o     A total of 57 net (57 gross) natural gas wells have been drilled during Q4
      2003 and Q1 2004 (30 wells and 27 wells, respectively) with a 100% success
      rate. Total costs incurred on these wells was $8.0 million ($2.0 million
      in Q4 2003 and $6.0 million in Q1 2004).

o     An additional 9 net (9 gross) wells will be drilled in the second quarter.

o     Pipelines and compression facilities were installed during the first
      quarter in order to process additional production from the new wells at a
      cost of $3.7 million.

o     As the result of an early spring break-up, completion and tie-in of these
      wells has been delayed and it is expected that these wells will all be
      on-stream by the end of the second quarter of 2004.

BANTRY

o     During the first quarter the Fund drilled 3.9 net (7 gross) wells at
      Bantry bringing the total number of wells drilled to 14.5 net (25 gross)
      since the property was acquired in December 2003.

o     A total of 11.3 net (19 gross) wells have been tested resulting in 8.8 net
      (15 gross) natural gas wells. The remaining wells will be tested when
      spring break-up is completed.

o     It is anticipated that the successful wells will be tied-in and on
      production by the end of the second quarter.



PRESS RELEASE                                                       May 13, 2004
Advantage Energy Income Fund                                        Page 3 of 15

o     In addition the Fund expended approximately $4.5 million on pipelines and
      compression in the first quarter to expand the productive capacity of the
      field.

o     25 additional well locations have been identified for drilling over the
      balance of 2004.

OTHER AREAS

o     At Shouldice, Alberta the Fund commenced a 38 well drilling program late
      in the first quarter. New production from this program will be added in
      the third quarter. In addition, the Fund expended $1.5 million to enhance
      the productive capacity of the field for this program.

o     At Nevis, Alberta the Fund drilled three successful 100% working interest
      horizontal oil wells which came on-stream late March and early April.

o     At Princess, Alberta a 50% working interest natural gas well was drilled
      and is expected to be on production late in the second quarter.

MANAGEMENT'S DISCUSSION & ANALYSIS

The following MD&A provides a detailed explanation of the financial and
operating results of Advantage Energy Income Fund ("Advantage" or "the Fund")
for the quarter ended March 31, 2004 and should be read in conjunction with the
financial statements contained within this press release and the audited
financial statements and MD&A for the year ended December 31, 2003.

All per barrel of oil equivalent ("boe") numbers are stated at a 6:1 conversion
rate for natural gas to oil.

CASH DISTRIBUTIONS

Cash distributions per Unit for the three months ended March 31, 2004 were $0.69
per Unit, or $26.3 million, an increase of 8% over the $0.64 per Unit paid in
the first quarter of 2003. The first quarter 2004 distributions were comprised
of $0.23 per month for each of January, February and March. The amount
distributed for the quarter represents 88% of total cash available for
distribution. Cash available for distribution is defined as cash flow from
operations less interest on convertible debentures. The remaining cash withheld
of $3.6 million was used to partially finance the Fund's ongoing capital
expenditure program. Since its inception on May 23, 2001 the Fund has
distributed $178.7 million or $6.58 per Unit.

      Cash distributions to Unitholders were paid as follows:



Period ended    Record date     Payment date     Distribution   Distribution per Unit
- -------------------------------------------------------------------------------------

Mar. 31, 2004   Mar. 31, 2004   Apr. 15, 2004     $   8,778               0.23

                                                  $  26,267           $   0.69
=====================================================================================


PRODUCTION

During the three months ended March 31, 2004 Advantage's natural gas production
increased by 39% to 75.6 mmcf/d compared to 54.5 mmcf/d for the quarter ended
March 31, 2003 and by 10.3 mmcf/d or 16% over the fourth quarter of 2003. The
increase in natural gas production is primarily due to the acquisition of
MarkWest Resources on December 2, 2003. MarkWest added approximately 20 mmcf/d
of new natural gas production to Advantage. Additional natural gas production
related to the Fund's active first quarter drilling program are expected to come
on-stream late in the second quarter.

Crude oil and natural gas liquids production averaged 2,841 bbls/d in the first
quarter of 2004 compared to 2,946 bbls/d for the quarter ending March 31, 2003.
The 4% decline in production from the first quarter of 2003 is due to a minor
property disposition of approximately 240 bbls/d and natural declines partially
offset by the acquisition of MarkWest Resources on December 2, 2003.

PRICES

During the three months ended March 31, 2004 Advantage's natural gas price
averaged $6.28 per mcf ($6.28 per mcf including hedging) compared to $7.65 per
mcf ($6.18 per mcf including hedging) in the first quarter of 2003. Advantage
did not have natural gas hedges in place during the first quarter of 2004. For
the three months ended March 31, 2004 AECO daily prices averaged $6.36 per mcf
compared to $7.95 per mcf in the same period in 2003.

Natural gas prices have remained relatively strong during the first quarter of
2004. Continued strength of natural gas has been attributed to (i) the strength
of crude oil prices which has eliminated the economic advantage of fuel
switching away from natural gas, (ii) the potential for a hotter than normal
summer and reduced coal inventories which may increase



PRESS RELEASE                                                       May 13, 2004
Advantage Energy Income Fund                                        Page 5 of 15

demand for gas-fired power generation and (iii) the US economy is showing signs
of sustained growth which will add to non-weather demand for natural gas.
Advantage continues to believe the pricing fundamentals for natural gas remain
strong.

Crude oil and NGLs prices averaged $40.93 per barrel ($40.93 per barrel
including hedging) in the first quarter of 2004 compared to $45.74 per barrel
($44.34 per barrel including hedging) in the three months ended March 31, 2003.
Advantage had no crude oil hedges in place in the first quarter of 2004. First
quarter 2004 prices for WTI crude oil averaged US$35.15 per barrel, 4% higher
than the US$33.80 per barrel realized during the first quarter of 2003.
Partially offsetting the increase in WTI prices was a stronger Canadian dollar
which averaged $US/$Cdn $0.76 in the first quarter of 2004 compared to $0.66 in
the first quarter of 2003.

Crude oil prices continued to be strong during the first quarter of 2004.
Factors that affect the continued strength of crude oil include (i) continued
conflict in the middle east, (ii) low global inventory levels and (iii) strong
world oil demand. All of these factors are expected to keep crude oil prices
high for the remainder of the year.

HEDGING

Advantage had no hedging contracts related to first quarter 2004 production. The
Fund currently has the following hedge contracts in place:

      Volume                       Effective Period            Average Price
      ----------------------------------------------------------------------

      Natural gas - AECO

      50,350 mcf/d         April 1, 2004 - December 31, 2004    $ 6.12/mcf
      10,450 mcf/d         January 1, 2005 - March 31, 2005     $ 6.30/mcf

At March 31, 2004 the mark to market valuation of Advantage's outstanding hedges
was a loss of $11.1 million. This amount has been included in the income
statement as an unrealized hedging loss with a corresponding hedging liability
recorded on the balance sheet. Advantage will continue to maintain a hedging
program in order to add stability to the level of cash distributions to
Unitholders.

ROYALTIES

During the first quarter of 2004 Advantage's royalties amounted to $10.6 million
(19.6% of pre-hedged revenue) compared to $8.2 million (16.5% of pre-hedged
revenue) in the first quarter of 2003. Total royalties in 2004 are higher as a
result of higher revenues. The increase in the royalty rate in 2004 is the
result of the acquisition of MarkWest Resources properties in December 2003
which attract higher royalty rates than other Advantage properties. Advantage
expects royalty rates to approximate 20% for the balance of 2004.

OPERATING COSTS

Operating costs for the three months ended March 31, 2004 amounted to $8.3
million or $5.92 per boe compared to $5.5 million or $5.09 per boe in the first
quarter of 2003. Operating costs steadily increased throughout 2003 due to
higher power costs and higher field costs associated with the shortage of
supplies, services and materials that have occurred as a result of very high
levels of industry activity. Advantage's increased operating costs over 2003 are
in line with overall industry trends.

GENERAL AND ADMINISTRATIVE AND MANAGEMENT FEES

General and administrative (G&A) expense in the first quarter of 2004 amounted
to $0.8 million or $0.60 per boe compared to $0.8 million or $0.76 per boe in
the first quarter of 2003. Total G&A expense in the first quarter was unchanged
from the prior year while G&A per boe declined by 21% as a result of increased
production.

Management fees for the three months ended March 31, 2004 amounted to $0.5
million or $0.37 per boe compared to $0.4 million or $0.39 per boe in the first
quarter of 2003. Management fees are calculated based on 1.5% of operating cash
flow which is defined as revenue less royalties and operating costs.

The Manager of the Fund is entitled to earn a performance incentive fee which is
calculated at the end of each year based on the total return of the Fund. At
March 31, 2004 no amount was paid to the Manager, nor is the Manager entitled to
receive any payment related to the Fund's performance for the first three months
of 2004 as the actual amount is calculated and paid on an annual basis only. If
the performance fee was paid at March 31, 2004, based on the performance of the
Trust in the first quarter, the total fee payable would be $5.6 million. The
Trust has accrued one



PRESS RELEASE                                                       May 13, 2004
Advantage Energy Income Fund                                        Page 6 of 15

quarter of this amount or $1.4 million for the first quarter of 2004. There is
no certainty that the fee accrued in the financial statements will be paid at
year end. Any performance incentive fee paid to the Manager at year end is
expected to be settled in Advantage Trust Units.

INTEREST

Interest expense for the three months ended March 31, 2004 amounted to $1.3
million ($0.91 per boe) compared to $1.6 million ($1.47 per boe) for the first
quarter of 2003. Lower interest expense in the first quarter of 2004 is the
result of lower average bank debt balances in 2004 combined with lower interest
rates.

TAXES

Current taxes are comprised primarily of capital tax, which amounted to $0.3
million for the three months ended March 31, 2004 compared to $0.4 million for
the same period of 2003. Capital taxes are determined based on debt and equity
levels at the end of the year. As a result of new legislation in 2003, capital
taxes are to be gradually eliminated over the next five years.

For the three months ended March 31, 2004 a future income tax recovery of $7.8
million was included in income compared to a $3.1 million recovery for the
comparable period in 2003. On March 31, 2004, Bill 27 Alberta Corporate Tax
Amendment Act, 2004, which reduces the corporate provincial tax rate by 1%, was
tabled and received first reading in the Alberta Legislative Assembly. As a
result Bill 27 is substantively enacted and a non-recurring benefit of $2.2
million was recorded in the first quarter of 2004. There was no similar tax rate
adjustment to income tax expense in the first quarter of 2003.

DEPLETION, DEPRECIATION AND ACCRETION OF ASSET RETIREMENT OBLIGATION

The depletion, depreciation and accretion (D,D&A) rate for the first quarter of
2004 was $14.24 per boe compared to $10.63 per boe for the first quarter of
2003. The D, D&A rate per boe increased in the first quarter of 2004 compared to
the first quarter of 2003 due the acquisition of MarkWest Resources and
revisions to the Fund's total proven reserves pursuant to National Instrument
51-101. Included in D,D&A is $0.2 million of accretion of the asset retirement
obligation. Costs subject to depletion include $7.1 million relating to the
capitalized portion of the asset retirement obligation in the first quarter of
2004. The retroactive application of the new accounting policy for asset
retirement obligations requires restatement of prior periods, which resulted in
the first quarter 2003 D,D&A rate to increase to $10.63 per boe compared to the
previously reported rate of $10.59 per boe and D,D&A expense to increase by $0.2
million.

FINANCIAL REPORTING UPDATE

Hedging Relationships

Effective in the Fund's first quarter of 2004, the new CICA Accounting Guideline
13 "Hedging Relationships" requires that hedging relationships be identified,
designated, documented and measured in order for the Fund to apply hedge
accounting. Although the Fund believes that all of the hedges Advantage enters
into are effective economic hedges, Advantage has elected to not use hedge
accounting. The Fund will be using the fair value method to account for all of
its hedge transactions. This method requires Advantage to mark to market at the
balance sheet date the fair value of all outstanding hedges. At March 31, 2004
the mark to market valuation of Advantage's outstanding hedges was a loss of
$11.1 million. This amount has been included in the income statement as an
unrealized hedging loss with a corresponding hedging liability recorded on the
balance sheet.

Asset Retirement Obligations

In March 2003 the CICA issued handbook section 3110 "Asset Retirement
Obligations" which requires liability recognition for retirement obligations
associated with the Fund's property and equipment. The obligations are initially
measured at fair value, which is the discounted future value of the liability.
The fair value is capitalized as part of the cost of the related assets and
depleted to earnings over the assets useful life. The liability accretes until
the retirement obligations are settled. Advantage adopted the new standard in
the first quarter of 2004. The impact to the Trust of the implementation of this
policy is disclosed in note 1 (b) of the March 31, 2004 financial statements.

Full Cost Accounting

Effective January 1, 2004 the Trust adopted CICA accounting guideline 16 "Oil
and Gas Accounting - Full Cost". This accounting guideline replaced CICA
accounting guideline 5, "Full cost accounting in the oil and gas industry".
Accounting guideline 16 modifies how the ceiling test calculation is performed.
The recoverability of a cost centre is tested by comparing the carrying value of
the cost centre to the sum of the undiscounted cash flows expected from the cost
centre. If the carrying value is not recoverable the cost centre is written down
to its fair value. Adopting accounting guideline 16 had no effect on the Trust's
financial results.

CONTRACTUAL OBLIGATIONS AND COMMITTMENTS

The Trust has contractual obligations in the normal course of operations
including purchase of assets and services, operating agreements, transportation
commitments and sales contracts. These obligations are of a recurring and
consistent nature and impact cash flow in an ongoing manner. The following is a
summary of the Fund's contractual obligations and commitments:

LIQUIDITY AND CAPITAL RESOURCES

Advantage's capital expenditures on development activities for the quarter
ending March 31, 2004 were $29.4 million net of $0.8 million of minor property
dispositions. Expenditures were focused on drilling, completions, pipelines and
compression at Medicine Hat, Bantry, Nevis and Shouldice. A total of 44 (39.6
net) wells were drilled during the first quarter of 2004. Production from this
drilling program is anticipated to come on-stream late in the second quarter of
2004.

===============================================================

Total bank debt outstanding at March 31, 2004 was $136.2 million. Advantage has
an agreement with a syndicate of three Canadian chartered banks that provides
for a $180 million facility consisting of $170 million extendible revolving loan
facility and a $10 million operating loan facility both of which mature on May
29, 2004. The credit facilities are secured by a $250 million floating charge
demand debenture, a general security agreement and a subordination agreement for
the Trust covering all assets and cash flows. At March 31, 2004 Advantage also
had a working capital deficit of $20.2 million.

Non-GAAP Measures

Cash flow from operations and per Unit and cash available for distribution and
per Unit are not recognized measures under the Canadian generally accepted
accounting principles (GAAP). Management believes that cash flow and cash
available for distribution are useful supplemental measures to analyse operating
performance and provide an indication of the results generated by the Trust's
principal business activities prior to the consideration of how those activities
are financed or how the results are taxed. Investors should be cautioned,
however, that these measures should not be construed as an alternative to net
income determined in accordance with GAAP as an indication of Advantage's
performance. Advantage's method of calculating these measures may differ from
other companies, and accordingly, they may not be comparable to measures used by
other companies.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS

All tabular amounts in thousands, except for per Unit amounts (unaudited)

The interim consolidated financial statements of Advantage Energy Income Fund
("Advantage") have been prepared by management in accordance with Canadian
generally accepted accounting principles using the same accounting policies as
those set out in note 2 to the consolidated financial statements for the period
ended December 31, 2003 except as described below. The interim consolidated
financial statements should be read in conjunction with the audited consolidated
financial statements of Advantage for the year ended December 31, 2003 as set
out in Advantage's Annual Report.

1.    CHANGE IN ACCOUNTING POLICIES

      (a) Petroleum and Natural Gas Properties and Related Equipment

      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 carrying amounts are assessed to be recoverable when the sum of the
      undiscounted 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 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.

      The Trust adopted the new accounting standard relating to full cost
      accounting effective January 1, 2004 and as at January 1, 2004 and March
      31, 2004 no write-down to the carrying value of petroleum and natural gas
      assets was required. Prior to January 1, 2004 the ceiling test amount was
      the sum of the undiscounted cash flows expected from the production of
      proved reserves, the lower of cost or market of unproved properties and
      the cost of major development projects less estimated future costs for
      administration, financing, site restoration and income taxes. The cash
      flows were estimated using period end prices and costs.

      (b) Asset Retirement Obligations

      The Trust has adopted 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 Trust's asset
      retirement obligation is recorded in the period in which it is incurred,
      discounted to its present value using the Trust's credit adjusted
      risk-free interest rate and the corresponding amount recognized by
      increasing the carrying amount of property, plant and equipment. The asset
      recorded is depleted on a unit of production basis over the life of the
      reserves. The liability amount is increased each reporting period due to
      the passage of time and the amount of accretion is charged to earnings 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.

      Previously, the Trust recognized a provision for estimated future removal
      and site restoration costs calculated on the unit-of-production method
      over the remaining proved reserves.

      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):

      (c) Hedging Relationships

      Effective January 1, 2004, CICA Accounting Guideline 13 "Hedging
      Relationships" requires that hedging relationships be identified,
      designated, documented and measured in order for the Fund to apply hedge
      accounting. Advantage has chosen not to apply hedge accounting and will
      instead use the fair value method. This method requires the fair value of
      the derivative financial instruments be recorded at each balance sheet
      date. In accordance with this method, the Fund has recorded an unrealized
      hedging loss of $11.1 million at March 31, 2004.

2.    ASSET RETIREMENT OBLIGATIONS

      The Trust's asset retirement obligations result from net ownership
      interests in petroleum and natural gas assets including well sites,
      gathering systems and processing facilities. The Trust estimates the total
      undiscounted and inflated amount of cash flows required to settle its
      asset retirement obligations is approximately $39.7 million which will be
      incurred between 2004 to 2054. A credit-adjusted risk-free rate of 7.0
      percent was used to calculate the fair value of the asset retirement
      obligations.

      A reconciliation of the asset retirement obligations is provided below:

      Due to the exercise price features in the Unit rights, management believes
      the fair value is not reliably determinable. Based on a March 31, 2004
      unit price of $18.97, the decrease in the intrinsic value of the Trust
      Unit Rights during first quarter of 2004 is approximately $172,000.

=====================================================================================================


      The convertible debentures and the related interest obligations are
      classified as equity on the consolidated balance sheet as the Trust may
      elect to satisfy the debenture interest and principle obligations by the
      issuance of Trust Units. During the three months ended March 31, 2004
      $4,766,000 debentures were converted resulting in the issuance of 315,575
      Advantage Units.

4.    FINANCIAL INSTRUMENTS

      As at March 31, 2004 the Fund has the following hedges in place:

      Volume                          Effective Period              Price
      ----------------------------------------------------------------------
      Natural gas - AECO

      50,350 mcf/d            April 1, 2004 - December 31, 2004   $ 6.12/mcf
      10,450 mcf/d            January 1, 2005 - March 31, 2005    $ 6.30/mcf

      As at March 31, 2004 the settlement value of the hedges outstanding was
      approximately $11.1 million and has been charged to income as an
      unrealized hedging loss.

5.    NON-CASH PERFORMANCE INCENTIVE

      The Manager of the Fund is entitled to earn an annual performance
      incentive fee which is calculated based on the total return of the Fund.
      At March 31, 2004 no amount was paid to the Manager, nor is the Manager
      entitled to receive any payment related to the Fund's first three months
      performance as the actual amount is only calculated and paid on an annual
      basis.

      The Manager earns the performance incentive fee when the Fund's total
      annual return exceeds 8%. The total annual return is calculated at the end
      of each year by dividing the year over year change in Unit price plus cash
      distributions by the opening Unit price. The 2004 opening Unit Price was
      $18.03. 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 average number of Units outstanding during the
      year) to determine the performance incentive. If the performance fee was
      paid at March 31, 2004 based on the performance of the Trust in the first
      quarter the total fee payable would be $5.6 million. The Trust has accrued
      one quarter of this amount or $1.4 million for the first quarter of 2004.
      It is expected that any fee earned be paid to the Manager in Advantage
      Trust Units and therefore the accrued fee to March 31, 2004 has been
      classified as Unitholders' Capital. The Manager does not receive any form
      of compensation in respect of acquisition or divestiture activities.
