These statements relate to future events or our future performance. All statements other than statements of historical fact may be forward-looking statements. Forward-looking statements are often, but not always, identified by the use of words such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar expressions. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. We and AOG believe the expectations reflected in those forward-looking statements are reasonable but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in, or incorporated by reference into, this annual information form should not be unduly relied upon. These statements speak only as of the date of this annual information form or as of the date specified in the documents incorporated by reference into this annual information form, as the case may be. In particular, this annual information form, and the documents incorporated by reference, contain forward-looking statements pertaining to the following: o the performance characteristics of our assets; o oil and natural gas production levels; o the size of the oil and natural gas reserves; o projections of market prices and costs and the related sensitivities of distributions; o supply and demand for oil and natural gas; o expectations regarding the ability to raise capital and to continually add to reserves through acquisitions and development; o treatment under governmental regulatory regimes; and o capital expenditures programs. The actual results could differ materially from those anticipated in these forward-looking statements as a result of the risk factors set forth below and elsewhere in this annual information form: o volatility in market prices for oil and natural gas; o liabilities inherent in oil and natural gas operations; o uncertainties associated with estimating oil and natural gas reserves; o competition for, among other things, capital, acquisitions of reserves, undeveloped lands and skilled personnel; o incorrect assessments of the value of acquisitions; o fluctuation in foreign exchange or interest rates; o stock market volatility and market valuations; o changes in income tax laws or changes in tax laws and incentive programs relating to the oil and gas industry and income trusts; o geological, technical, drilling and processing problems and other difficulties in producing petroleum reserves; and o the other factors discussed under "Risk Factors". Statements relating to "reserves" or "resources" are deemed to be forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions, that the resources and reserves described can be profitably produced in the future. Readers are cautioned that the foregoing lists of factors are not exhaustive. The forward looking statements contained in this annual information form and the documents incorporated by reference herein are expressly qualified by this cautionary statement. Except as required by law, neither the Trust, the Manager, nor AOG undertakes any obligation to publicly update or revise any forward-looking statements and readers should also carefully consider the matters discussed under the heading "Risk Factors" in this annual information form. 6 ADVANTAGE ENERGY INCOME FUND GENERAL Advantage Energy Income Fund ("ADVANTAGE", the "TRUST", the "FUND", "US", "WE", or "OUR" and, where the context requires, also includes the Trust's subsidiaries) is an entity that provides monthly cash distributions to its holders ("UNITHOLDERS") of trust units ("TRUST UNITS") of the Trust.

(2) Cash distributions are made to Unitholders monthly based upon our cash flow. In accordance with the terms of the Trust Indenture and the Shareholder Agreement, holders of Trust Units are entitled to direct us as to how to vote in respect of all matters to be placed before us, including the selection of directors of AOG, approving AOG's financial statements, and appointing the auditors of AOG, who shall be the same as our auditors. The Shareholder Agreement provides that the Unitholders are entitled to elect a majority of the board of directors of AOG (the "AOG BOARD OF DIRECTORS") and the Manager has the right to designate two of such directors. GENERAL DEVELOPMENT OF THE BUSINESS 2003 On July 8, 2003, we completed the issue, by way of short form prospectus, of $30,000,000 aggregate principal amount of 9% convertible unsecured subordinated debentures, which debentures mature on August 1, 2008 and are convertible into Trust Units at $17.00 per Trust Unit (the "9% DEBENTURES"). The net proceeds of the offering were used to fund an expanded capital expenditure program and to repay debt. On December 2, 2003, we completed a second issue, by way of short form prospectus, of 5,100,000 Trust Units at $15.75 per Trust Unit for gross proceeds of $80,325,000 and $60,000,000 aggregate principal amount of 8.25% convertible unsecured subordinated debentures, which debentures mature on February 1, 2009 and are convertible into Trust Units at $16.50 per Trust Unit (the "8.25% DEBENTURES"). The net proceeds of the offering were used to fund the acquisition of MarkWest, to reduce amounts outstanding under our credit facility and to fund drilling and exploitation capital expenditures. In conjunction with the completion of the financing, we also announced the completion of the MarkWest acquisition for total cash consideration of $96,800,000 prior to adjustments. 8 2004 On September 15, 2004, we completed an issue, by way of short form prospectus, of 3,500,000 Trust Units and $75,000,000 aggregate principal amount of 7.50% convertible unsecured subordinated debentures (the "7.50% DEBENTURES") and $50,000,000 aggregate principal amount of 7.75% convertible unsecured subordinated debentures (the "7.75% DEBENTURES") to partially finance the $186,000,000 (before closing adjustments) acquisition of certain petroleum and natural gas properties and related assets (the "ACQUIRED ASSETS") from Anadarko (the "ASSET ACQUISITION"). The 7.50% Debentures mature on October 1, 2009 and are convertible into Trust Units at a price of $20.25 per Trust Unit. The 7.75% Debentures mature on December 1, 2011 and are convertible into Trust Units at a price of $21.00 per Trust Unit. The Asset Acquisition has an effective date of July 1, 2004. The Business Acquisition Report in respect of the Asset Acquisition, dated September 30, 2004, was filed in accordance with Part 8 of National Instrument 51-102 Continuous Disclosure Obligations ("NI 51-102") and is incorporated herein by reference. On December 21, 2004, we announced the closing of our acquisition of Defiant (the "DEFIANT ACQUISITION") by way of plan of arrangement (the "ARRANGEMENT") under section 193 of the ABCA. Pursuant to the Arrangement, shareholders of Defiant could elect to receive (i) 0.201373 of a Trust Unit for each Defiant share, (ii) 0.201373 of an AOG exchangeable share for each Defiant share, or (iii) $2.79889 per Defiant share and the balance of the consideration in Trust Units as set out in option (i). In addition, Defiant shareholders received one sixth of one common share of Defiant Resources Corporation, a newly incorporated exploration company. As a result of this transaction, we paid total cash consideration of $34,000,000, issued 3,666,286 Trust Units and issued 1,450,030 AOG exchangeable shares. 2005 On February 9, 2005, we completed an issue, by way of short form prospectus, of 5,250,000 Trust Units at $21.65 per Trust Unit for gross proceeds of $113,662,500. The net proceeds of the offering were used to pay down debt incurred in the Defiant Acquisition, for our 2005 capital expenditure program and for general corporate purposes. On December 9, 2005, the Trust Units were listed and posted for trading on the New York Stock Exchange (the "NYSE") under the trading symbol "AAV". We believe the listing on the NYSE will result in improved liquidity for all Unitholders, greater access to the U.S. capital markets, and improved cost of capital for future acquisitions. ANTICIPATED CHANGES IN THE BUSINESS As at the date hereof, we do not anticipate that any material change in our business shall occur during the balance of the 2006 financial year. DESCRIPTION OF OUR BUSINESS AND OPERATIONS ADVANTAGE ENERGY INCOME FUND We are a limited purpose trust and are restricted to: 1. investing in the Initial Permitted Securities, the Permitted Investments, Subsequent Investments and such other securities and investments as AOG may determine, provided that under no circumstances shall the Trustee, AOG or the Manager purchase or authorize the purchase of any security, asset or investment (collectively a "Prohibited Investment") on our behalf or using any of our assets or property which are defined as "foreign property" under subsection 206(1) of the INCOME TAX ACT (Canada) ("TAX ACT") or are a "small business security" as that expression is used in Part LI of the Regulations to the Tax Act or would result in us not being considered either a "unit trust" or a "mutual fund trust" for purposes of the Tax Act at the time such investment was made; 2. disposing of any part of the Trust Fund, including, without limitation, any Permitted Investments; 3. acquiring the Royalty and other royalties in respect of Resource Properties; 9 4. temporarily holding cash, and Permitted Investments (including investments in AOG) for the purposes of paying Trust expenses and Trust liabilities, paying amounts payable by us in connection with the redemption of any Trust Units, and making distributions to Unitholders; 5. acquiring or investing in securities of AOG or any other subsidiary of ours to fund the acquisition, development, exploitation and disposition of all types of petroleum and natural gas related assets, including, without limitation, facilities of any kind and whether effected through the acquisition of assets or the acquisition of shares or other form of ownership interest in any entity, the substantial majority of the assets of which are comprised of like assets; 6. undertaking such other business and activities including investing in securities as shall be approved by AOG from time to time provided that we shall not undertake any business or activity which is a Prohibited Investment (as defined in the Trust Indenture); and to pay the costs, fees and expenses associated therewith or incidental thereto. In accordance with the terms of the Trust Indenture, we will make cash distributions to our Unitholders of the interest income earned from the Long Term Notes and Medium Terms Notes and principal repayments, royalty income earned on the Royalty, dividends (if any) received on, and amounts, if any, received on redemption of, Common Shares and Preferred Shares, and income and distributions received from any Permitted Investments after expenses and capital expenditures, any cash redemptions of Trust Units, and other expenditures. See "Additional Information Respecting Advantage Energy Income Fund - Cash Distributions". ADVANTAGE OIL & GAS LTD. AOG is actively engaged in the business of oil and gas exploration, development, acquisition and production in the provinces of Alberta, British Columbia and Saskatchewan. We employ a strategy to maintain production from AOG's existing production base while focusing capital expenditures on low-risk development opportunities. As a practice, AOG may manage the risk associated with changes in commodity prices by entering into oil or natural gas hedges related only to specific acquisition or project economics. See "Risk Factors". AOG generally sells or farms out higher risk projects while actively pursuing growth opportunities through oil and gas property acquisitions, as well as through corporate acquisitions. AOG targets acquisitions that are accretive to net asset value and that increase our reserve and production base per Trust Unit outstanding. Acquisitions must also meet reserve life index criteria and exhibit low risk opportunities to increase reserves and production. It is currently intended that AOG will finance acquisitions and investments through bank financing, the issuance of additional Trust Units from treasury and the issuance of subordinated convertible debentures, maintaining prudent leverage. ADVANTAGE INVESTMENT MANAGEMENT LTD. Pursuant to the Management Agreement, the Manager has agreed to act as manager of the Trust and AOG. The AOG Board of Directors has retained the Manager to provide comprehensive management services and has delegated certain authority to the Manager to assist in the administration and regulation of the day-to-day operations of the Trust and AOG and assist in executive decisions which conform to the general policies and general principles previously established by the board of directors. The Manager is entitled to designate two directors to serve on the board of directors. The Manager also provides executive officers to AOG, subject to the approval of the AOG Board of Directors.

We evaluate the appropriate financing alternatives closely and have made use of all these options dependent on the given investment situation and the capital markets. We maintain a capital structure that is similar to our industry peer group and that will maximize the investment return to Unitholders as compared to the cost of financing. We expect to continue using all financing alternatives available to continue pursuing our oil and gas development strategy. The assorted financing instruments have certain inherent costs which we consider in the economic evaluation of pursuing any development opportunity. OTHER OIL AND GAS INFORMATION Our properties are spread geographically throughout the Western Canadian Sedimentary Basin. This sedimentary basin covers a large portion of the 4 western Canadian provinces, with the majority of our properties concentrated in Alberta, along with a few in northeast British Columbia and also southeast Saskatchewan. These properties produce from a variety of various aged geological formations and reservoirs. We have managed our portfolio so that we now operate more than 85% of our properties. This allows us to control the nature and timing of the capital investments necessary to maximize the potential in developing these assets. Our properties can be divided on the broad basis of commodity and of production type. Light or medium gravity oil accounts for 35% of our production and 33% of our reserves. A further 65% of production and 67% of reserves are natural gas. SHALLOW GAS PROPERTIES A significant portion of our production comes from shallow gas properties at Medicine Hat, Bantry, Shouldice and Wainwright. These projects are all located in southern Alberta and occur between 500 and 1,200 meters of depth. Typical of shallow gas, these properties are resource plays which require a large number of wells to extract the very large in place reserves at relatively low per well production rates. As a result, they have a long production life (long reserve life index or RLI). These reservoirs consist of low permeability strata, requiring fracture stimulation to enhance and induce productivity. The wells are gathered by an extensive network of low pressure pipelines which feed into large central gas compression facilities. All of these properties have been downspaced to allow for multiple gas wells per section, ranging from just 2 per section at Wainwright to the current 16 per section at Medicine Hat. MEDICINE HAT, ALBERTA The Medicine Hat (Bowmanton) property is located 20 km northeast of the City of Medicine Hat in the heart of the southeastern shallow gas area. We have a 100% working interest in 24 sections of land from which production is taken from all of the main shallow gas producing formations including the Medicine Hat "A", "C" and "D" sands, as well as both the Upper and Lower Milk River sands. When the property was acquired in January 2002 there were 115 wells producing approximately 5.2 MMcf/d of natural gas. In 2002 and 2003, several recompletions along with an additional 164 wells were 19 drilled. Late in 2003 an additional 57 wells were drilled and completed in 2004. In 2004 a further 68 wells were drilled and completed. Late in 2005 and early in 2006, 30 low production rate wells were recompleted. As a result, current production from this property is 15.3 MMcf/d from approximately 385 wells. No new wells were added in 2005. Compression capacity was increased in late 2003 by approximately 10 MMcf/d to accommodate added production from the drilling programs. No additional compression was added in 2004 or 2005. Sproule evaluated our reserves in the area and assigned 58.7 bcf of proved natural gas reserves and 9.9 bcf of probable reserves. As such, this property is our largest property on an assigned reserves basis. BANTRY, ALBERTA Bantry is located immediately east of the town of Brooks straddling the TransCanada Highway. The property consists of 86 sections of land ranging between 50% and 100% working interest. This property was acquired in November 2003. During 2004 we drilled 48 (gross) wells. An additional 5 (gross) wells were drilled during 2005. Of these 5 wells, one has been abandoned. Production occurs primarily from Basal Colorado Formation channel sandstones and various sandstones within the Bow Island Formation. Drilling depth is shallow with average wells less than 1,000 meters. Natural gas is gathered into our operated compression and dehydration facilities. Current net production from this area is approximately 1,286 boe/d. Additional compression capacity was added in the first quarter of 2004 to handle incremental volumes. In 2005, a rationalization of compression facilities was undertaken to reduce future operating costs and free up capital from surplus compression equipment. The Sproule Report assigns 11.7 bcf of proven natural gas reserves and 18.7 Mbbls of proven NGL reserves to this property. In addition, 6.6 bcf of probable natural gas reserves and 10.6 Mbbls of probable NGL reserves have been assigned to this property. SHOULDICE, ALBERTA The Shouldice area of southern Alberta is located approximately 50 km southeast of the City of Calgary. We have an average working interest of more than 85% in 34 sections of land and operate in excess of 90% of our production in the area. Much of this acreage is downspaced to accommodate additional drilling. Current natural gas production of approximately 4.1 MMcf/d is produced on a co-mingled basis from the Medicine Hat Formation sands with various Belly River Formation sands. During 2003, 20 net wells were added to the existing 70 producing wells. Both natural gas and crude oil are produced and gathered through our facilities of varying working interests. An additional 4 MMcf/d of new compression capacity was added in 2004 to handle additional production. In 2005, one new well was drilled and produces at an approximate rate of 500 Mcf/d. Additional drilling, potentially up to 10 wells, is planned on this property in 2006. The Sproule Report assigns 9.1 bcf of proven natural gas reserves and 90 Mbbls of proven crude oil and NGLs to this property. In addition, 3.8 bcf of probable natural gas reserves and 39 Mbbls of probable crude oil and NGL reserves have been assigned to this property. WAINWRIGHT, ALBERTA The Wainwright property is located approximately 175 kilometres southeast of the City of Edmonton. We have varying working interests in this property averaging 85% in approximately 175 sections of land. Current net production from the property is approximately 4.3 MMcf/d natural gas and 24 bbls/d NGLs and crude oil. In 2002, we swapped out virtually all of our heavy oil assets in this area for producing natural gas assets in our adjacent area of Vermilion. Natural gas production occurs from the Manville Group and Viking Formations at shallow depths of between 450 and 700 meters. We operate 95% of our production in this area as well as own and operate a majority interest in an extensive gas gathering system tied into three Advantage-operated gas compression facilities. In 2003, 23.3 net wells were drilled for a combination of Viking and Upper Mannville zones. No drilling occurred on this property in 2004 and 2005. 20 Sproule evaluated our proved reserves in the Wainwright area and assigned 8.1 bcf of natural gas. Probable reserves in this area were evaluated by Sproule at 2.3 bcf of natural gas. CONVENTIONAL OIL AND NATURAL GAS PROPERTIES Conventionally produced oil and gas properties constitute the majority of our property portfolio. Some of these properties produce only natural gas or, occasionally, only oil. In most instances both products co-exist in the production and we operate in excess of 80% of these properties. In 2005 the bulk of our capital expenditures occurred on these properties, and was significantly spread out amongst many individual projects. NEVIS, ALBERTA The Nevis property is situated 60 km east of Red Deer. Nevis consists of approximately 55 sections of land with an average working interest over 80% and is 95% operated. Natural gas production occurs from numerous shallow depth horizons including the Edmonton, Belly River and Viking formations. Oil and natural gas is produced from the slightly deeper reservoirs (1,200 m) of the Glauconite, Ostacod and Ellerslie formations within the Mannville Group. The main zone of interest however occurs at 1,600 meters in Devonian aged carbonates of the Big Valley Member of the Wabamun Formation. In 2004, Wabamun oil was principally targeted, although gas was also drilled in both the Wabamun and shallower horizons. Development of the oil is being accomplished by horizontal drilling. Crude oil quality to date has been exceptional ranging for the most part between 35o and 42o API. Natural gas is gathered through our pipelines and processed at a third party plant. Oil is trucked from single well batteries. In 2005, 13 horizontal wells and 4 vertical wells were drilled. Current production is approximately 2,000 boe/d. Currently the pool is spaced to allow for 4 wells per section. Currently, the property is being reviewed to evaluate the potential waterflood of this reservoir to increase future recoveries and to evaluate future downspacing. The Sproule Report assigns 17.6 bcf of proven natural gas reserves and 3,693 Mbbls of proven crude oil and NGL reserves to this property. In addition, 5.5 bcf of probable natural gas reserves and 1,285 Mbbls of probable crude oil and NGL reserves have been assigned to this property. CHIP LAKE, ALBERTA The Chip Lake property is located 125 kilometers west of the City of Edmonton. The property produces light crude oil (37o API) with associated gas. Production at the end of 2005 is approximately 490 boe/d. This property was acquired in December 2004. Prior to the acquisition, the previous owner had constructed a central sour oil and water handling facility without appropriate Energy Utilities Board ("EUB") approval. We are involved in extensive discussion with the EUB and public stakeholders to resolve this issue in 2006. Currently the property will continue to produce from single well batteries under maximum rate limitation allowables until the issues are resolved. The Sproule Report has assigned proved reserves for this property of 2,128 Mbbls of crude oil and NGL's and 1.9 Bcf of natural gas. In addition, 2,648 Mbbls of probable crude oil and NGL's and 1.8 Bcf of probable natural gas reserves have been assigned to the property. SUNSET/VALLEYVIEW, ALBERTA This area is located approximately 100 km east of the City of Grande Prairie, just north of the town of Valleyview. It consists of a group of three main producing properties: Sunset A, Sunset B, and Valleyview. All three properties produce from the Triassic Montney Formation, with some production from younger Cretaceous reservoirs such as the Gething. These properties were acquired in December 2004 by virtue of the acquisition of Defiant. SUNSET A - Production is predominantly oil at approximately 32oAPI to date. This pool is unitized and we have a 70% working interest in the unit which we also operate. During 2005, two wells were drilled and spaced across the unit which evaluated the viability of moving the full pool onto a downspaced basis. Plans are to drill an additional 14 wells in 2006. Current net production from the Sunset A unit is 240 bbls/d of crude oil and 240 Mcf/d of natural gas. The Sunset A pool was discovered in 1960 and has a long history of stable low decline production. It is one of our longest life reservoirs. 21 SUNSET B - Production from this Montney reservoir is predominantly natural gas although there is a thin oil column. Oil gravity is light at 33oAPI. We have a 100% interest in this pool. Defiant began operations at Sunset B in mid 2000 and commissioned a sour gas processing plant and gathering system late that year. The plant and gathering system were expanded in December 2003, increasing total throughput capacity to 12 MMcf/d. There is potential to add further compression and upgrades in modular increments to increase throughput capacity to approximately 20 MMcf/d. Current production from Sunset B is 1.9 MMcf/d and 100 bbls/d. A small amount of gas is produced as well from the Cretaceous and Bluesky reservoirs. Sunset B has a long production history and long reserve life. The original discovery well, Defiant Sunset 2-14-70-20 W5M, has been on production for 28 years, and has recovered 350 Mboe to date and still produces 12 bbls/d and 85 Mcf/d. No wells were drilled in 2005 and plans for 2006 are being investigated. VALLEYVIEW - The Sunset B and Valleyview properties are in close proximity to each other, with the Valleyview property connected to the Sunset B gas processing plant by a twelve kilometre pipeline where natural gas, NGLs and light oil from both properties are processed. We have a 93% average working interest in the pool. One new well was drilled in 2005 and there are plans to drill 2 new wells in 2006. Production at Valleyview is essentially all natural gas with current rates of approximately 3.0 MMcf/d. All wells require fracture stimulation to bring them on production and cost approximately $750,000 drilled, completed and tied-in. For the three properties, Sunset A, Sunset B and Valleyview, the Sproule Report assigns 19.8 bcf of proven natural gas reserves and 2,096 Mbbls of proven crude oil and NGL reserves to this property. In addition, 13.2 bcf of probable natural gas reserves and 2,274 Mbbls of probable crude oil and NGL reserves have been assigned to this property. STODDART/NORTH PINE, BRITISH COLUMBIA The Stoddart/North Pine area lies just west of the Town of Fort St. John in northeast British Columbia. The area contains multiple producing horizons, predominantly natural gas from the Permian Belloy Formation and oil from the Triassic, Charlie Lake Formation. Historically, production from this area has very low decline, is low cost and requires minimal capital expenditures. We own an interest in 30 producing wells (22 net) in the area. We operate approximately 80% of the natural gas production and have a 40% working interest in the North Pine Charlie Lake oil pool. The area includes 12,000 gross (9,176 net) acres of undeveloped land. Current production from this area is 3.2 MMcf/d of natural gas and 177 bbls/d of light oil and NGLs. Sproule evaluated our proved reserves in the area and assigned 10.9 bcf of natural gas and 561 Mbbls of crude oil and NGLs. In addition, 4.2 bcf of probable natural gas reserves and 265 Mbbls of probable crude oil and NGLs reserves have been assigned to this property. SOUTHEAST SASKATCHEWAN This area consists of a host of individual properties all within the Williston Sedimentary Basin in the southeast corner of Saskatchewan. We operate the majority of this production at 100% which comes principally from the major properties being the Ordovician Red River Formation oil at Midale, Hardy and Froude, Devonian Winnipegosis Formation oil at Steelman and oil from Mississippian Midale/Frobisher Formations at Steelman, Weyburn and Workman. We drilled two multi-leg horizontal Frobisher wells at Steelman in 2005. Also one vertical Red River oil well and a vertical Mannville water injector well were drilled at Froude. Numerous well re-activations and re-entries were undertaken in 2005 in several pools. Production from Saskatchewan, all light crude oil, was 1,720 bbls/d. Southeast Saskatchewan will continue to be an active area for us with additional drilling and/or side track re-entries planned in 2006 at Hardy, Midale and Steelman. The Workman property is being reviewed for unitization and waterflood. Sproule evaluated our reserves in the area and assigned 3,556 Mbbls of proven crude oil. Probable reserves in this area were evaluated by Sproule at 2,940 Mbbls of crude oil. BRAZEAU RIVER, ALBERTA The Brazeau River property is located approximately 50 km west of the town of Drayton Valley. The property produces sour light oil and natural gas primarily from Devonian aged Nisku pinnacle reefs. The majority of the production is from a non-operated 50% working interest in the Nisku C, D and E pools and a 17% working interest in the Nisku A unit. The 22 property was acquired in the package of assets purchased from Anadarko in 2004. Sweet natural gas is also produced from eight natural gas wells out of reservoirs in either of the Cretaceous aged Cardium, Viking or Lower Mannville Formations. Major facility interests include a 25.7% working interest in the West Pembina Sour Gas Plant and a 31.6% working interest in the Brazeau River Gas Plant. In 2005, this property experienced numerous production issues related to various delays in servicing the wells by the operator. These issues have been resolved and production has been restored. Current net production from the property is approximately 2.5 MMcf/d natural gas and 310 bbls/d NGLs and crude oil. Sproule evaluated our proved reserves in the Brazeau River area and assigned 3.0 bcf of natural gas and 329 Mbbls of crude oil and NGLs. Probable reserves in this area were evaluated by Sproule at 2.5 bcf of natural gas and 220 Mbbls of crude oil and NGLs. OPEN LAKE (WILLESDEN GREEN), ALBERTA The Willesden Green property is located approximately 35 km north of the Town of Rocky Mountain House. The property was acquired in the package of assets purchased from Anadarko in 2004. We operate and have in excess of a 90% working interest in the Willesden Green property. Oil and natural gas production from this property is multi-zoned from various Cretaceous and Jurassic reservoirs including the Rock Creek, Ellerslie, Ostracod, Viking, Second White Specks and Belly River Formations. Net current production from the property is approximately 3.2 mmcf/d natural gas and 432 bbls/d NGLs and crude oil. Sproule evaluated our proved reserves in the Willesden Green area and assigned 5.5 bcf of natural gas and 660 Mbbls of crude oil and NGLs. Probable reserves in this area were evaluated by Sproule at 2.4 bcf of natural gas and 335 Mbbls of crude oil and NGLs. OIL AND GAS WELLS The following table sets forth the number and status of wells as at December 31, 2005 in which we have a working interest.

The land expirations do not consider our 2006 exploitation and development program that may result in extending or eliminating such potential expirations. We closely monitor land expirations as compared to our development program with the strategy of minimizing undeveloped land expirations relating to significant identified opportunities. FORWARD CONTRACTS Our operational results and financial condition will be dependent on the prices received for oil and natural gas production. Oil and natural gas prices have fluctuated widely in recent years. Such prices are primarily determined by economic, and in the case of oil prices, political factors. Supply and demand factors, as well as weather, general economic conditions, and conditions in other oil and natural gas regions of the world also impact prices. Any upward or downward movement in oil and natural gas prices could have an effect on our financial condition, thus impacting the cash distributions made to Unitholders. In the past, we have entered into short term hedging agreements which have limited the risk associated with downward changes in commodity prices. However, these agreements have also meant that we have foregone the benefit of any price increases. As a future practice, we may manage the risk associated with changes in commodity prices by entering into oil or natural gas price hedges. These hedging activities could expose us to losses or gains. However, such oil or natural gas price hedges will only be entered into on specific acquisitions and projects. To the extent that we engage in risk management activities related to commodity prices, we will be subject to credit risk associated with the parties with which we contract. This credit risk will be mitigated by entering into contracts with only stable and creditworthy parties and through the frequent review of our exposure to these entities entities. We currently do not have any hedge contracts or forward commitments in place. ADDITIONAL INFORMATION CONCERNING ABANDONMENT AND RECLAMATION COSTS We estimate the costs to abandon and reclaim all our shut-in and producing wells, facilities, gas plants, pipelines, batteries and satellites. No estimate of salvage value is netted against the estimated cost. Our model for estimating the amount and timing of future abandonment and reclamation expenditures was done on an operating area level. Estimated expenditures for each operating area are based upon Sproule's methodology, which details the cost of abandonment and reclamation for the major properties that we hold. Each property was assigned an average cost per well to abandon and reclaim the wells in an area and abandonment and reclamation costs have been estimated over a 50 year period. We estimate that we will incur reclamation and abandonment costs on 2,433 (gross) producing and non-producing wells. Costs to abandon and reclaim the producing wells totals $45.8 million ($11.6 million discounted at 10%) and are included in the estimate of future net revenue. The additional liability associated with non-producing wells, pipelines and facilities reclamation costs was estimated to be $48.2 million ($3.5 million discounted at 10%), and was not deducted in estimating future net revenue. Facility reclamation costs are scheduled to be incurred in the year following the end of the reserve life of our associated reserves under the assumption that decommissioning of plant/facilities are mobile assets with a long useful life. 24 Abandonment and reclamation costs included in the estimate of future net revenue for the next three years are $0.6 million in 2006, $0.8 million in 2007 and $1.3 million in 2008. TAX HORIZON In 2005, we did not pay any income related taxes. However, we did pay capital taxes that are determined based on the debt and equity levels of the Trust at the end of a given taxation year. As a result of legislation in 2003, capital taxes are to be gradually eliminated over the next four years. In our structure, the operating company utilizes available tax pools to significantly reduce taxable income and makes other required payments to the Trust transferring both income and associated tax liability to the Unitholders. Therefore, it is expected, based on current legislation that no cash income taxes are to be paid by the operating company in the future and it is our intent to continue with the current arrangement. For the 2005 distributions, 40% were taxable to the Canadian Unitholders and 60% were deemed a return of capital. For U.S. Unitholders, 2005 distributions were 44% taxable and 56% were deemed a return of capital.

Columns set forth above may not add due to rounding. 2. The crude oil, natural gas liquids and natural gas reserve estimates presented in the Sproule Report are based on the definitions and guidelines contained in the COGE Handbook. A summary of those definitions are set forth below. "COGE HANDBOOK" means the Canadian Oil and Gas Evaluation Handbook prepared jointly by the Society of Petroleum Evaluation Engineers (Calgary chapter) and the Canadian Institute of Mining, Metallurgy & Petroleum; "DEVELOPMENT COSTS" means costs incurred to obtain access to reserves and to provide facilities for extracting, treating, gathering and storing the oil and gas from reserves. More specifically, development costs, including applicable operating costs of support equipment and facilities and other costs of development activities, are costs incurred to: (a) gain access to and prepare well locations for drilling, including surveying well locations for the purpose of determining specific development drilling sites, clearing ground, draining, road building, and relocating public roads, gas lines and power lines, pumping equipment and wellhead assembly; (b) drill and equip development wells, development type stratigraphic test wells and service wells, including the costs of platforms and of well equipment such as casing, tubing, pumping equipment and wellhead assembly; (c) acquire, construct and install production facilities such as flow lines, separators, treaters, heaters, manifolds, measuring devices and production storage tanks, natural gas cycling and processing plants, and central utility and waste disposal systems; and (d) provide improved recovery systems. "EXPLORATION COSTS" means costs incurred in identifying areas that may warrant examination and in examining specific areas that are considered to have prospects that may contain oil and gas reserves, including costs of drilling exploratory wells and exploratory type stratigraphic test wells. Exploration costs may be incurred both before acquiring the related property and after acquiring the property. Exploration costs, which include applicable operating costs of support equipment and facilities and other costs of exploration activities, are: 27 (a) costs of topographical, geochemical, geological and geophysical studies, rights of access to properties to conduct those studies, and salaries and other expenses of geologists, geophysical crews and others conducting those studies; (b) costs of carrying and retaining unproved properties, such as delay rentals, taxes (other than income and capital taxes) on properties, legal costs for title defence, and the maintenance of land and lease records; (c) dry hole contributions and bottom hole contributions; (d) costs of drilling and equipping exploratory wells; and (e) costs of drilling exploratory type stratigraphic test wells. "GROSS" means: (f) in relation to our interest in production and reserves, our "Trust gross reserves", which are our interest (operating and non-operating) share before deduction of royalties and without including any royalty interest of the Trust; (g) in relation to wells, the total number of wells in which we have an interest; and (h) in relation to properties, the total area of properties in which we have an interest. "NET" means: (i) in relation to our interest in production and reserves, our interest (operating and non-operating) share after deduction of royalties obligations, plus our royalty interest in production or reserves; (j) in relation to wells, the number of wells obtained by aggregating our working interest in each of our gross wells; and (k) in relation to our interest in a property, the total area in which we have an interest multiplied by the working interest owned by us. RESERVE CATEGORIES Reserves are estimated remaining quantities of oil and natural gas and related substances anticipated to be recoverable from known accumulations, from a given date forward, based on: o analysis of drilling, geological, geophysical and engineering data; o the use of established technology; and o specified economic conditions. Reserves are classified according to the degree of certainty associated with the estimates. (a) PROVED RESERVES are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves. (b) PROBABLE RESERVES are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves. Other criteria that must also be met for the categorization of reserves are provided in the COGE Handbook. 28 Each of the reserve categories (proved and probable) may be divided into developed and undeveloped categories: (c) DEVELOPED RESERVES are those reserves that are expected to be recovered from existing wells and installed facilities or, if facilities have not been installed, that would involve a low expenditure (for example, when compared to the cost of drilling a well) to put the reserves on production. The developed category may be subdivided into producing and non-producing. (i) DEVELOPED PRODUCING RESERVES are those reserves that are expected to be recovered from completion intervals open at the time of the estimate. These reserves may be currently producing or, if shut-in, they must have previously been on production, and the date of resumption of production must be known with reasonable certainly. (ii) DEVELOPED NON-PRODUCING RESERVES are those reserves that either have not been on production, or have previously been on production, but are shut-in, and the date of resumption of production is unknown. (d) UNDEVELOPED RESERVES are those reserves expected to be recovered from known accumulations where a significant expenditure (for example, when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves classification (proved, probable) to which they are assigned. LEVELS OF CERTAINTY FOR REPORTED RESERVES The qualitative certainty levels referred to in the definitions above are applicable to individual reserve entities (which refers to the lowest level at which reserves calculations are performed) and to reported reserves (which refers to the highest level sum of individual entity estimates for which reserves are presented). Reported reserves should target the following levels of certainty under a specific set of economic conditions: (a) at least a 90 percent probability that the quantities actually recovered will equal or exceed the estimated proved reserves; and (b) at least a 50 percent probability that the quantities actually recovered will equal or exceed the sum of the estimated proved plus probable reserves. Additional clarification of certainty levels associated with reserves estimates and the effect of aggregation is provided in the COGE Handbook. MARKETING Our crude oil and natural gas production is primarily sold through marketing companies at current market prices. These contracts are generally for less than a year and are cancellable on 30 days notice. Approximately 15% of our natural gas production is sold to aggregators who accumulate production from various producers and market the gas on behalf of the group. Such contracts are reserve specific and continue for the life of production from the specified reserves. CYCLICAL AND SEASONAL IMPACT OF INDUSTRY Our operational results and financial condition will be dependent on the prices received for oil and natural gas production. Oil and natural gas prices have fluctuated widely during recent years and are determined by supply and demand factors, including weather and general economic conditions, as well as conditions in other oil and natural gas regions. Any decline in oil and natural gas prices could have an adverse effect on our financial condition. We mitigate such price risk through closely monitoring the various commodity markets and establishing hedging programs, as deemed necessary, to provide stability to Unitholders' cash distributions and lock-in high netbacks on production volumes. See "Other Oil and Gas Information - Forward Contracts" for our current hedging program. 29 RENEGOTIATION OR TERMINATION OF CONTRACTS As at the date hereof, we do not anticipate that any aspect of our business will be materially affected in the remainder of 2006 by the renegotiation or termination of contracts or subcontracts. ENVIRONMENTAL CONSIDERATIONS We are pro-active in our approach to environmental concerns. Procedures are in place to ensure that the utmost care is taken in the day-to-day management of our oil and gas properties. All government regulations and procedures are followed in strict adherence to the law. We believe in well abandonment and site restoration in a timely manner to ensure minimal damage to the environment and lower overall costs to us. COMPETITIVE CONDITIONS We are a member of the petroleum industry, which is highly competitive at all levels. We compete with other companies for all of our business inputs, including exploitation and development prospects, access to commodity markets, acquisition opportunities, available capital and staffing. We strive to be competitive by maintaining a strong financial condition and by utilizing current technologies to enhance exploitation, development and operational activities. HUMAN RESOURCES As at December 31, 2005, we employ 80 full-time employees, 68 of which are located in the head office and 12 of which are located in the field. We also employ 9 consultants. ADDITIONAL INFORMATION RESPECTING ADVANTAGE ENERGY INCOME FUND TRUST UNITS An unlimited number of Trust Units may be created and issued pursuant to the Trust Indenture. As at December 31, 2005, 57,846,324 Trust Units were issued and outstanding. Each Trust Unit represents an equal fractional undivided beneficial interest in any distributions from, and in any net assets of, the Trust in the event of termination or winding up of the Trust. The beneficial interests in the Trust are divided into two classes, as follows: (i) Trust Units, which are entitled to the rights, subject to limitations, restrictions and conditions set out in the Trust Indenture, as summarized herein and (ii) "special voting units", which shall be issued to a trustee and which are entitled to such number of votes at meetings of Unitholders as is equal to the number of Trust Units reserved for issuance that such special voting units represent, such number of votes and any other rights or limitations to be prescribed by the AOG Board of Directors. As at the date hereof there is one special voting unit outstanding. The special voting unit gives AOG the flexibility to acquire the securities of another issuer in consideration for securities which are ultimately exchangeable for Trust Units. All Trust Units are of the same class with equal rights and privileges. Each Trust Unit is transferable, entitles the holder thereof to participate equally in distributions, including the distributions of net income and net realized capital gains of the Trust, and distributions on liquidation, is fully paid and non assessable and entitles the holder thereof to one vote at all meetings of Unitholders for each Trust Unit held. The Trust Units do not represent a traditional investment and should not be viewed by investors as "shares" in either AOG or the Trust. Corporate law does not govern the Trust and the rights of Unitholders. As holders of Trust Units in the Trust, the Unitholders will not have the statutory rights normally associated with ownership of shares of a corporation including, for example, the right to bring "oppression" or "derivative" actions. The rights of Unitholders are specifically set forth in the Trust Indenture. In addition, trusts are not defined as recognized entities within the definitions of legislation such as the BANKRUPTCY AND INSOLVENCY ACT (Canada) and the COMPANIES' CREDITORS ARRANGEMENT ACT (Canada). As a result, in the event of an insolvency or restructuring, a Unitholder's position as such may be quite different than that of a shareholder of a corporation. The price per Trust Unit is a function of anticipated distributable income from AOG and the combined ability of the AOG Board of Directors and the Manager to effect long term growth in the value of the Trust. The market price of the Trust Units 30 will be sensitive to a variety of market conditions including, but not limited to, interest rates, commodity prices and our ability to acquire additional assets. Changes in market conditions may adversely affect the trading price of the Trust Units. A return on an investment in the Trust is not comparable to the return on an investment in a fixed-income security. The recovery of an initial investment in the Trust is at risk, and the anticipated return on such investment is based on many performance assumptions. Although the Trust intends to make distributions of its available cash to holders of Trust Units, these cash distributions may be reduced or suspended. The actual amount distributed will depend on numerous factors including: the financial performance of AOG, debt obligations, working capital requirements and future capital requirements. In addition, the market value of the Trust Units may decline if the Trust's cash distributions decline in the future, and that market value decline may be material. It is important for an investor to consider the particular risk factors that may affect the industry in which it is investing, and therefore the stability of the distributions that it receives. See "Risk Factors". The after-tax return from an investment in Trust Units to Unitholders subject to Canadian income tax can be made up of both a return on capital and a return of capital. That composition may change over time, thus affecting an investor's after-tax return. Returns on capital are generally taxed as ordinary income in the hands of a Unitholder. Returns of capital are generally tax-deferred (and reduce the Unitholder's cost base in the Trust Unit for tax purposes). EXCHANGEABLE SHARES As at December 31, 2005, AOG had 104,672 Exchangeable Shares outstanding. The Exchangeable Shares were issued in connection with our acquisition of Defiant. Each Exchangeable Share is exchangeable for Trust Units at any time (subject to the provisions of the Voting and Exchange Trust Agreement), on the basis of the applicable exchange ratio in effect at that time, in accordance with the share provisions applicable to such shares and the terms and provisions of the Voting and Exchange Trust Agreement. The exchange ratio was initially equal to one upon issuance of the Exchangeable Shares and will increase on each date that a distribution is paid by us on the Trust Units. The exchange ratio will decrease on each record date for the payment of dividends on the Exchangeable Shares. The holders of Exchangeable Shares are not entitled to any vote at meetings of shareholders of AOG but are, through the Special Voting Unit of Advantage held by the Trustee as trustee under the Voting and Exchange Trust Agreement, entitled to vote (on the basis of the number of votes equal to the number of Trust Units into which the Exchangeable Shares are then exchangeable) with the holders of Trust Units as a class. In addition, holders are provided with all information sent by us to Unitholders. Holders of Exchangeable Shares will be entitled to receive, as and when declared by the AOG Board of Directors in its sole discretion from time to time, such cash dividends as may be declared thereon by the AOG Board of Directors. It is not anticipated that dividends will be declared or paid on the Exchangeable Shares. The Exchangeable Shares will be redeemable by AOG, in certain circumstances, and will be retractable by holders of Exchangeable Shares, in certain circumstances. Exchangeable Shares not previously redeemed or retracted will be redeemed by AOG or purchased by us on January 15, 2008. TRUST UNITHOLDER LIMITED LIABILITY The Trust Indenture provides that no Trust Unitholder will be subject to any liability in connection with the Trust or its obligations and affairs and, in the event that a court determines our Unitholders are subject to any such liabilities, the liabilities will be enforceable only against, and will be satisfied only out of the Trust Unitholder's share of our assets. Pursuant to the Trust Indenture, we will indemnify and hold harmless each Trust Unitholder from any cost, damages, liabilities, expenses, charges and losses suffered by a Trust Unitholder resulting from or arising out of such Trust Unitholder not having such limited liability. The Trust Indenture provides that all written instruments signed by or on behalf of us must contain a provision to the effect that such obligation will not be binding upon our Unitholders personally. Notwithstanding the terms of the Trust Indenture, Unitholders may not be protected from our liabilities to the same extent as a shareholder is protected from the liabilities of a corporation. Personal liability may also arise in respect of claims against the Trust (to the extent that claims are not satisfied by the Trust Fund) that do not arise under contracts, including claims in tort, claims for taxes and possibly certain other statutory liabilities. The possibility of any personal liability to Unitholders of this nature arising is considered unlikely in view of the fact that our sole business activity is to hold securities, and all of the business operations currently carried on by AOG will be carried on by a corporate entity, directly or indirectly. 31 Our business and that of our wholly-owned subsidiary, AOG, is conducted, upon the advice of counsel, in such a way and in such jurisdictions as to avoid as far as possible any material risk of liability to our Unitholders for claims against us, including obtaining appropriate insurance, where available, for the operations of AOG and having written agreements, signed by or on our behalf, include a provision that such obligations are not binding upon our Unitholders personally. ISSUANCE OF TRUST UNITS The Trust Indenture provides that Trust Units or rights to acquire Trust Units may be issued at the times, to the persons, for the consideration, and on the terms and conditions that the AOG Board of Directors determines. The Trust Indenture also provides that immediately after any PRO RATA distribution of Trust Units to all Unitholders in satisfaction of any non-cash distribution, the number of outstanding Trust Units will be consolidated such that each Trust Unitholder will hold, after the consolidation, the same number of Trust Units as the Trust Unitholder held before the non-cash distribution. In this case, each certificate representing a number of Trust Units prior to the non-cash distribution is deemed to represent the same number of Trust Units after the non-cash distribution and the consolidation. CASH DISTRIBUTIONS The amount of cash to be distributed annually per Trust Unit shall be equal to a PRO RATA share of interest on the Notes, royalty income from the Royalty, dividends on or in respect of shares of AOG received by us and income from the Permitted Investments; less: (i) our administrative expenses and other obligations; and (ii) amounts which may be paid by us in connection with any cash redemptions of Trust Units. AOG may apply some or all of its cash flow to capital expenditures to develop the Oil and Natural Gas Properties of AOG or to acquire additional Oil and Natural Gas Properties prior to making any distributions to us in the form of principal repayments on the Notes or dividends on the Common Shares, Non-Voting Shares or Preferred Shares. If, on any Distribution Record Date, the Trustee determines that we do not have cash in an amount sufficient to pay the full distribution to be made on such Distribution Record Date in cash or if any cash distribution should be contrary to any subordination agreement, the distribution payable to Unitholders on such Distribution Record Date may, at the option of the Trustee, include a distribution of additional Trust Units having an equal value to the cash shortfall. Trust Units will be issued pursuant to exemptions under applicable securities laws, discretionary exemptions granted by applicable securities regulatory authorities or a prospectus or similar filing. We derive interest income from our holdings of the Notes. It is expected that our income will generally be limited to: (i) the interest received on the principal amount of the Notes; (ii) royalty income received on the Royalty; and (iii) dividends (if any) received on shares of AOG. See "Additional Information Respecting Advantage Oil & Gas Ltd. - Notes". The AOG Board of Directors intends for the Trust to make monthly cash distributions. Cash distributions will be made monthly to the Unitholders of record on the last day of each month (unless such day is not a Business Day, in which case the date of record shall be the next following Business Day) and shall be payable on the 15th day of each month or, if such day is not a Business Day, the following Business Day or such other date as determined from time to time by the Trustee. Pursuant to the provisions of the Trust Indenture all income earned by the Trust in a fiscal year, not previously distributed in that fiscal year, must be distributed to Unitholders of record on December 31. This excess income, if any, will be allocated to Unitholders of record at December 31 but the right to receive this income, if the amount if not determined and declared payable at December 31, will trade with the Trust Units until determined and declared payable in accordance with the rules of the Toronto Stock Exchange. To the extent that a Unitholder trades Trust Units in this period they will be allocated such income but will dispose of their right to receive such distribution. REDEMPTION RIGHT Trust Units are redeemable at any time on demand by the holders thereof upon delivery to us of the certificate or certificates representing such Trust Units, accompanied by a duly completed and properly executed notice requesting redemption. Upon our receipt of the redemption request, all rights to and under the Trust Units tendered for redemption shall be surrendered and the holder thereof shall be entitled to receive a price per Trust Unit (the "REDEMPTION PRICE") equal to the lesser of: (i) 85% of the "market price" of the Trust Units on the principal market on which the Trust Units are quoted for trading during the 10 trading-day period commencing immediately after the date on which the Trust Units are surrendered for 32 redemption (the "REDEMPTION DATE"); and (ii) the "closing market price" on the principal market on which the Trust Units are quoted for trading on the Redemption Date. For the purposes of this calculation, "market price" is an amount equal to the simple average of the closing price of the Trust Units for each of the trading days on which there was a closing price, provided that, if the applicable exchange or market does not provide a closing price but only provides the highest and lowest prices of the Trust Units traded on a particular day, the market price shall be an amount equal to the simple average of the highest and lowest prices for each of the trading days on which there was a trade, and provided further that if there was trading on the applicable exchange or market for fewer than five of the 10 trading days, the market price shall be the simple average of the following prices established for each of the 10 trading days: the average of the last bid and last ask prices for each day on which there was no trading; the closing price of the Trust Units for each day that there was trading if the exchange or market provides a closing price; and the average of the highest and lowest prices of the Trust Units for each day that there was trading, if the market provides only the highest and lowest prices of Trust Units traded on a particular day. The "closing market price" shall be: an amount equal to the closing price of the Trust Units if there was a trade on the date; an amount equal to the average of the highest and lowest prices of the Trust Units if there was trading and the exchange or other market provides only the highest and lowest prices of Trust Units traded on a particular day; and the average of the last bid and last ask prices if there was no trading on the date. The aggregate Redemption Price payable by us in respect of any Trust Units surrendered for redemption during any calendar month shall be satisfied by way of a cash payment on or before the last day of the following month; provided that the entitlement of Unitholders to receive cash upon the redemption of their Trust Units is subject to the limitations that: (i) the total amount payable by us in respect of such Trust Units and all other Trust Units tendered for redemption in the same calendar month shall not exceed $100,000 (provided that the Trustee may, in its sole discretion, waive such limitation in respect of any calendar month); (ii) at the time such Trust Units are tendered for redemption the outstanding Trust Units shall be listed for trading on a stock exchange or traded or quoted on any other market which the Trustee considers, in its sole discretion, provides representative fair market value prices for the Trust Units; and (iii) the normal trading of Trust Units is not suspended or halted on any stock exchange on which the Trust Units are listed (or, if not listed on a stock exchange, on any market on which the Trust Units are quoted for trading) on the Redemption Date or for more than five trading days during the 10-day trading period commencing immediately after the Redemption Date. If a Trust Unitholder is not entitled to receive cash upon the redemption of Trust Units as a result of the foregoing limitations, then the Redemption Price for such Trust Units shall be the Fair Market Value thereof (as defined in the Trust Indenture), as determined by the Trustee in the circumstances described in subparagraphs (ii) and (iii) above, and shall, subject to any applicable regulatory approvals, be paid and satisfied by way of distribution IN SPECIE of a PRO RATA number of Long Term Notes (in a minimum amount of $100.00 and integral multiples of $1.00), from time to time outstanding (i.e., in a principal amount equal to the Redemption Price). No fractional Long Term Notes will be distributed and where the number of Long Term Notes to be received by a Trust Unitholder includes a fraction, such number shall be rounded to the next lowest whole number. We shall be entitled to all interest paid, or accrued and unpaid, on the Long Term Notes on or before the date of the distribution IN SPECIE. If we do not hold Long Term Notes having a sufficient principal amount outstanding to effect such payment, we will be entitled to create and, subject to any applicable regulatory approvals, issue in satisfaction of the Redemption Price our own debt securities (the "REDEMPTION NOTES") having terms and conditions substantially the same as the Long Term Notes, and with recourse of the holder limited to our assets. Holders of such Long Term Notes and Redemption Notes will be required to acknowledge that they are subject to the subordination agreements described below under the heading "Additional Information Regarding Advantage Oil & Gas Ltd. - Notes". Long Term Notes and Redemption Notes may not be qualified investments for trusts governed by registered retirement savings plans, registered retirement income funds and deferred profit sharing plans if the Trust ceases to qualify as a mutual fund trust. It is anticipated that the redemption right will not be the primary mechanism for holders of Trust Units to dispose of their Trust Units. Long Term Notes or Redemption Notes which may be distributed IN SPECIE to Unitholders in connection with a redemption will not be listed on any stock exchange and no market is expected to develop in such Long Term Notes or Redemption Notes. 33 MEETINGS OF UNITHOLDERS The Trust Indenture provides that meetings of Unitholders must be called and held for, among other matters, the election or removal of the Trustee, the appointment or removal of our auditors, the approval of amendments to the Trust Indenture (except as described under "Additional Information Respecting Advantage Energy Income Fund - Amendments to the Trust Indenture"), the sale of our assets in their entirety or substantially in their entirety (other than as part of an internal reorganization), the termination of the Trust and the direction of the Trustee as to the selection of the directors of AOG. Meetings of Unitholders will be called and held annually for, among other things, the election of the Trustee, the appointment of our auditors, and the direction of the Trustee as to the selection of the directors of AOG. A resolution appointing or removing a Trustee, our auditors, or the direction of the Trustee as to the selection of the directors of AOG must be passed by a simple majority of the votes cast by Unitholders. The balance of the foregoing matters must be passed by at least 66?% of the votes cast at a meeting of Unitholders called for such purpose. A meeting of Unitholders may be convened at any time and for any purpose by the Trustee and must be convened if requisitioned by the holders of not less than 20% of the Trust Units then outstanding by a written requisition. A requisition must, among other things, state in reasonable detail the business proposed to be transacted at the meeting. Unitholders may attend and vote at all meetings of Unitholders either in person or by proxy and a proxyholder need not be a Trust Unitholder. Two persons present in person or represented by proxy and representing, in the aggregate, at least 10% of the votes attaching to all outstanding Trust Units shall constitute a quorum for the transaction of business at all such meetings. The Trust Indenture contains provisions as to the notice required and other procedures with respect to the calling and holding of meetings of Unitholders. The next annual and special meeting of Unitholders is scheduled for April 26, 2006. INFORMATION AND REPORTS We will furnish to Unitholders such financial statements (including quarterly and annual financial statements) and other reports as are, from time to time, required by applicable law, including prescribed forms needed for the completion of Unitholders' tax returns under the Tax Act and equivalent provincial legislation. Prior to each meeting of Unitholders, the Trustee will provide the Unitholders (along with notice of such meeting) a proxy form and an information circular containing information similar to that required to be provided to shareholders of a Canadian public corporation. The AOG Board of Directors will ensure that AOG provides us with proper disclosure as to its business and financial operations and sufficient information and materials on a timely basis to allow us to meet our public reporting requirements. With respect to material changes, the AOG Board of Directors will ensure that AOG provides timely disclosure to us as if AOG were a public corporation. TAKEOVER BIDS The Trust Indenture contains provisions to the effect that if a takeover bid is made for the Trust Units and not less than 90% of the Trust Units (other than Trust Units held at the date of the takeover bid by or on behalf of the offeror or associates or affiliates of the offeror) are taken up and paid for by the offeror, the offeror will be entitled to acquire the Trust Units held by Unitholders who did not accept the takeover bid on the terms offered by the offeror. THE TRUSTEE The Trust Indenture provides that the Trustee shall exercise its powers and carry out its functions thereunder as Trustee honestly, in good faith and in the best interests of the Trust and the Unitholders and, in connection therewith, shall exercise that degree of care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances. The initial term of the Trustee's appointment was until the first annual meeting of Unitholders. The Trustee is reappointed or changed every year as may be determined by a majority of the votes cast at a meeting of our Unitholders. The Trustee may 34 resign upon providing 60 days notice to us. The Trustee may also be removed by special resolution of our Unitholders. Such resignation or removal becomes effective upon the acceptance or appointment of a successor trustee. DELEGATION OF AUTHORITY, ADMINISTRATION AND TRUST GOVERNANCE The AOG Board of Directors has generally been delegated our significant management decisions and the Manager has been retained to administer the Trust on behalf of the Trustee. In particular, the Trustee has delegated to the AOG Board of Directors responsibility for any and all matters relating to, among other things: (a) any offering of our securities, including: (i) ensuring compliance with all applicable laws; (ii) all matters relating to the content of any offering documents, the accuracy of the disclosure contained therein, and the certification thereof; (iii) all matters concerning any subscription agreements or underwriting or agency agreements providing for the sale of Trust Units or securities convertible for or exchangeable into Trust Units or rights to Trust Units; and (iv) all matters concerning the adoption of a unitholder rights plan; (b) all matters concerning the terms of, and amendment from time to time of, material contracts; (c) all matters relating to the redemption of Trust Units; (d) the determination of any Distribution Record Date other than the last day of each calendar month and the payment of cash distributions to Unitholders; (e) the determination of any borrowings under the Trust Indenture; (f) our acquisition of Permitted Investments and Subsequent Investments and the negotiation of agreements respecting Subsequent Investments; (g) maintaining our books and records and providing timely reports to Unitholders; (h) our financial statements and the financial statements of AOG; (i) the continued listing of our Trust Units on any exchange and to maintain our status as a reporting issuer, including press releases and material change reports as required by the continuous disclosure requirements of applicable securities legislation; and (j) the Initial Permitted Securities. Unitholders are entitled to elect a majority of the AOG Board of Directors pursuant to the terms of the Shareholder Agreement. Subject to the ultimate authority of the AOG Board of Directors, AOG and the Trust will be managed by the Manager. For more information as to the AOG Board of Directors, see "Additional Information Respecting Advantage Oil & Gas Ltd. - Management of AOG". DECISION-MAKING Although the Manager will provide certain advisory and management services to us pursuant to the Management Agreement, the AOG Board of Directors will supervise the management of our business and affairs, including our business and affairs delegated to AOG. In particular, significant operational decisions and all decisions relating to: (i) the acquisition and disposition of properties, assets or securities (individually or in the aggregate with respect to any single type of security) for a purchase price or proceeds in excess of $2,000,000; (ii) the approval of annual operating and capital expenditure budgets; and (iii) establishment of credit facilities, will be made by the AOG Board of Directors. In addition, the Trustee has delegated certain matters to the AOG Board of Directors, including making all decisions relating to: (i) issuance of additional Trust Units; and (ii) the determination of the amount of distributable income. Any amendment to any material contract to which we are a party will require the approval of the AOG Board of Directors on our behalf. The AOG Board of Directors generally intends to hold regularly scheduled meetings to review the business and affairs of the Trust and AOG and to make any necessary decisions relating thereto. LIABILITY OF THE TRUSTEE The Trustee, its directors, officers, employees, shareholders and agents shall not be liable to any Trust Unitholder or any other person, in tort, contract or otherwise, in connection with any matter pertaining to the Trust or the Trust Fund, arising from the exercise by the Trustee of any powers, authorities or discretion conferred under the Trust Indenture, including, without limitation, any action taken or not taken in good faith in reliance upon any documents that are, PRIMA FACIE, properly executed, any depreciation of, or loss to, the Trust Fund incurred by reason of the sale of any asset, any inaccuracy in any evaluation provided by the Manager or any other appropriately qualified person, any reliance upon any such evaluation, any action or failure to act of the Manager, AOG, or any other person to whom the Trustee has, with the consent of AOG, delegated any of its duties hereunder, or any other action or failure to act (including failure to compel in any way any former trustee to redress any breach of trust or any failure by the Manager or AOG to perform its duties under or delegated to it under the Trust Indenture or any material contract), unless such liabilities arise out of the gross negligence, wilful default or fraud of the Trustee or any of its directors, officers, employees, shareholders or agents. If the Trustee has retained an appropriate expert, adviser or legal counsel with respect to any matter connected with its duties under the Trust Indenture or any material contract, the Trustee may act or refuse to act based upon the advice of such expert, adviser or legal counsel, and the Trustee shall not be liable for and shall be fully protected from any loss or liability occasioned by any action or refusal to act based upon the advice of any such expert, adviser or legal counsel. In the exercise of the powers, authorities or discretion 35 conferred upon the Trustee under the Trust Indenture, the Trustee is and shall be conclusively deemed to be acting as Trustee of the assets of the Trust and shall not be subject to any personal liability for any debts, liabilities, obligations, claims, demands, judgments, costs, charges or expenses against or with respect to the Trust or the Trust Fund. In addition, the Trust Indenture contains other customary provisions limiting the liability of the Trustee. AMENDMENTS TO THE TRUST INDENTURE The Trust Indenture may be amended or altered, from time to time, by at least 66 2/3% of the votes cast at a meeting of our Unitholders called for such purpose. The Trustee may, without the approval of the Unitholders, make certain amendments to the Trust Indenture, including amendments: 1. for the purpose of ensuring continuing compliance with applicable laws (including the Tax Act), regulations, requirements or policies of any governmental or other authority having jurisdiction over the Trustee or over the Trust; 2. ensuring that we will satisfy the provisions of each of Sections 108(2)(a) and 132(6) of the Tax Act, as from time to time amended or replaced; 3. which, in the opinion of the Trustee, provide additional protection for or benefit to the Unitholders; 4. to remove any conflicts or inconsistencies in the Trust Indenture or making corrections, including the correction or rectification of any ambiguities, defective provisions, errors, mistakes or omissions, which are, in the opinion of the Trustee, necessary or desirable and not prejudicial to the Unitholders; 5. which, in the opinion of the Trustee, are necessary or desirable as a result of changes in taxation laws; and 6. removing or curing inconsistencies between the Trust Indenture and the Material Contracts (as such term is defined in the Trust Indenture) which are, in the opinion of the Trustee, necessary or desirable and not prejudicial to the Unitholders. TERM OF THE TRUST AND SALE OF SUBSTANTIALLY ALL ASSETS The Trust has been established for a term ending December 31, 2095. Pursuant to the Trust Indenture, termination of the Trust or the sale or transfer of our assets in their entirety or substantially in their entirety, except as part of an internal reorganization of the our assets as approved by the AOG Board of Directors, requires approval by at least 66?% of the votes cast at a meeting of the Unitholders. EXERCISE OF VOTING RIGHTS ATTACHED TO COMMON SHARES The Trust Indenture provides that the Trustee may vote securities of AOG held by it at any meeting of shareholders of AOG as well as any Permitted Investments held, from time to time, as part of the Trust Fund which carry voting rights. However, the Trustee may not, under any circumstances whatsoever, vote any AOG securities or any other Permitted Investments which carry voting rights to authorize the sale, lease or exchange of all or substantially all of the property of AOG or any other entity owned directly or indirectly by us which represents more than 51% of the Trust Fund, except as part of a reorganization of AOG and any one or more of our directly or indirectly owned subsidiaries without the approval of at least 66?% of the votes cast at a meeting of the Unitholders called for such purpose.

DISTRIBUTION POLICY It is anticipated that income received will be from: (i) the interest received on the principal amount of the Notes; (ii) royalty income from the Royalty; and (iii) the dividends received from the shares of AOG. The Trustee makes monthly cash distributions to Unitholders of the interest income earned from the Notes, royalty income from the Royalty and dividends, if any, received on Common Shares, after expenses, if any, and any cash redemptions of Trust Units. See "Risk Factors - Oil and Natural Gas Prices/Delay in Cash Distributions/Dependence on AOG". SHARE CAPITAL AOG is authorized to issue an unlimited number of Common Shares, Non-Voting Shares, Preferred Shares and Exchangeable Shares. AOG is the sole holder of the issued and outstanding Common Shares. There are no Non-Voting Shares or Preferred Shares issued and outstanding. AOG is also the sole holder of the outstanding Notes. The following is a description of the rights attaching to the Common Shares, Non-Voting Shares, Preferred Shares, Exchangeable Shares and Notes. COMMON SHARES Each Common Share entitles its holder to receive notice of and to attend all meetings of the shareholders of AOG and to one vote at such meetings. The holders of Common Shares are, at the discretion of the AOG Board of Directors and subject to applicable legal restrictions, entitled to receive any dividends declared by the AOG Board of Directors on the Common Shares. The holders of Common Shares are entitled to share equally in any distribution of the assets of AOG upon the liquidation, dissolution, bankruptcy or winding-up of AOG or other distribution of its assets among its shareholders for the purpose of winding-up its affairs. Such participation is subject to the rights, privileges, restrictions and conditions attaching to any instruments having priority over the Common Shares. 39 NON-VOTING SHARES The Non-Voting Shares have identical rights to the Common Shares except that holders of Non-Voting Shares are not generally entitled to receive notice of or attend at meetings of shareholders of AOG or to vote their shares at such meetings. PREFERRED SHARES The Preferred Shares may be issued, from time to time, in one or more series, each series consisting of such number of Preferred Shares as determined by the AOG Board of Directors, who may also fix the designations, rights, privileges, restrictions and conditions attached to the shares of each series of Preferred Shares. No Preferred Shares are presently issued and outstanding. The Preferred Shares of each series shall, with respect to payment of dividends and distributions of assets in the event of liquidation, dissolution or winding-up of AOG, whether voluntary or involuntary, or any other distribution of the assets of AOG among its shareholders for the purpose of winding-up its affairs, rank on a parity with the Preferred Shares of every other series and shall be entitled to preference over the Common Shares and the shares of any other class ranking junior to the Preferred Shares. EXCHANGEABLE SHARES As at December 31, 2005, AOG had 104,672 Exchangeable Shares outstanding. The Exchangeable Shares were issued in connection with our acquisition of Defiant. See "Additional Information Respecting Advantage Energy Income Fund - Exchangeable Shares". NOTES The following is a summary of the material attributes and characteristics of the Notes. This summary does not purport to be complete and is qualified in its entirety by reference to the provisions of the Note Indentures, pursuant to which the Notes are issued. PAYMENT UPON MATURITY On maturity and subject to any applicable subordination restrictions, AOG will repay the indebtedness represented by the Notes by paying to the Note Trustee, in lawful money of Canada, an amount equal to the principal amount of the outstanding Notes, together with accrued and unpaid interest thereon. RANKING Payment of the principal and interest (other than regularly scheduled interest and principal at maturity, provided no default on Senior Indebtedness (as hereinafter defined) has occurred and payment of such interest or principal is not otherwise required to be suspended in accordance with the terms of subordination agreements which may be entered into with the holders of Senior Indebtedness (as herein defined)) on the Notes will be subordinated in right of payment, as set forth in the Note Indentures, to the prior payment in full of the principal of and accrued and unpaid interest on, and all other amounts owing in respect of, all senior indebtedness ("SENIOR INDEBTEDNESS") which is defined as: (a) all indebtedness, obligations and liabilities of AOG in respect of borrowed money (including the deferred purchase price of property), other than: (i) indebtedness evidenced by the Note Indentures; and (ii) indebtedness which, by the terms of the instrument creating or evidencing the same, is expressed to rank in right of payment equally with or subordinate to the indebtedness evidenced by the Note Indentures; and (b) from and after the commencement of, and during the continuance of, any creditor proceedings (including bankruptcy, liquidation, winding-up, dissolution, restructuring or arrangement proceedings), all indebtedness, obligations and liabilities of AOG, other than indebtedness, obligations and liabilities of AOG represented by the Notes. The Note Indentures provide that in the event of any creditor proceedings relative to AOG, the holders of all Senior Indebtedness, which would include bank debt and suppliers of AOG, will be entitled to receive payment in full before the holders of the Notes are entitled to receive any payment. Any amount of property received contrary to these provisions shall be held in trust for and paid over to the holders of Senior Indebtedness. 40 In the event of any creditor proceedings, the indebtedness represented by the Notes is not to be classified with any Senior Indebtedness for voting or distribution, which means that holders of Senior Indebtedness may vote separately from the holders of Notes in respect of any restructuring or arrangement proposal regarding AOG. DEFAULT The Note Indentures provides that any of the following shall constitute an "Event of Default": (i) default in payment of the principal of the Notes when the same becomes due; (ii) the failure to pay the interest obligations of the Notes for a period of 12 months; (iii) default on any indebtedness exceeding $10,000,000; (iv) certain events of winding-up, liquidation, bankruptcy, insolvency or receivership; (v) the taking of possession by an encumbrancer of all or substantially all of the property of AOG; or (vi) default in the observance or performance of any other covenant or condition of the Note Indenture and the continuance of such default for a period of 30 days after notice in writing has been given by the Note Trustee to AOG specifying such default and requiring AOG to rectify the same. SUBORDINATION AGREEMENTS Pursuant to the terms of the Note Indentures, the Note Trustee may enter into subordination agreements with the holders of certain Senior Indebtedness under which the Note Trustee, on behalf of the holders of Notes, may agree directly with a holder of Senior Indebtedness in implementation of and/or in addition to the subordination terms described under "Ranking" directly above. The Note Trustee may give a holder of Senior Indebtedness a power of attorney to be exercised in any creditor proceedings to enforce the terms thereof. The Note Trustee may also agree to ensure that any transferee of Notes (or other securities of AOG) agrees to be bound by the provisions of the subordination agreements. LONG TERM NOTES The aggregate principal amount of Long Term Notes as at December 31, 2005 was $540,140,328. The Long Term Notes mature on December 31, 2031.

The Long Term Notes are issuable only as fully-registered notes in minimum denominations of $100.00 and integral multiples of $1.00. REDEMPTION OF LONG TERM NOTES The Long Term 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 Long Term Note Indenture, where the AOG Board of Directors believe the indebtedness represented by the Long Term 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. MEDIUM TERM NOTES The original aggregate principal amount of Medium Term Notes was $259,200,000 ("ORIGINAL PRINCIPAL AMOUNT") and the aggregate principal amount of the Medium Term Notes as at December 31, 2005 was $200,664,757. The Medium Term Notes consist of a series of notes, which as of December 31, 2005, includes Medium Term Notes bearing interest at rates between 7.75% and 10.375% per annum, payable twice annually, and maturing between December 31, 2012 and December 21, 2015. The principal and interest on the Medium Term Notes are payable in lawful money of Canada. The Medium Term Notes are issuable only as fully-registered notes in minimum denominations of $100.00 and integral multiples of $1.00. PRINCIPAL REPAYMENTS AND REDEMPTION OF MEDIUM TERM NOTES From time to time and in any event not less frequently than each anniversary of December 31, AOG shall make principal repayments on the Notes in an aggregate amount equal to not less than 5% of the Original Principal Amount (and, if applicable, the aggregate principal amount of any additional Notes issued under the Medium Term Note Indenture in excess of the Original Principal Amount (the "SUPPLEMENTAL PRINCIPAL AMOUNT")), provided, however that during the period 41 commencing on September 30, 2004 and ending on December 31 of the year ended five years before the Maturity Date, AOG shall make, in aggregate, principal payments on the Notes in an amount equal to not less than 50% of the Original Principal Amount.

In the event that AOG makes principal repayments on the Notes pursuant to this section of the Medium Note Indenture and there is more than one holder thereof, such principal prepayments shall be made as near as may be pro rata as between the holders and without discrimination or preference, based upon the aggregate principal amount of Notes held by them (rounded, if necessary, to the nearest One Dollar ($1.00)). THE ROYALTY AGREEMENT Pursuant to the Royalty Agreement, AOG has granted to us the Royalty on AOG's interest in Petroleum Substances within, upon or under all of AOG's developed and undeveloped Canadian Oil and Natural Gas Properties The Royalty will consist of the right to receive a monthly payment from AOG equal to the "Royalty Production Income", which in respect of any period for which Royalty is calculated, means 95% of the production revenues from the Properties less an equivalent portion of the amount of all deductions permitted under the Royalty Agreement. The Royalty does not constitute an interest in land and we are not entitled to take our share of production in kind or to separately sell or market our share of Petroleum Substances. Pursuant to the Royalty Agreement approximately 95% of the economic benefit derived from the assets of AOG accrues to the benefit of the Fund and ultimately to us and our Unitholders. The term of the Royalty Agreement will be for so long as there are Properties to which the Royalty Agreement applies. If AOG wishes to dispose of any properties that will result in proceeds in excess of $2 million, approval of the AOG Board of Directors is required to approve such disposition.

In addition, Unitholders will be entitled to direct us as to how to vote our shares in AOG on any proposed amendment to the Shareholder Agreement, where such amendment affects the rights of Unitholders to elect a majority of the AOG Board of Directors. We will not be entitled, without the direction of Unitholders, to exercise our rights as the sole shareholder of AOG except as set forth above. It is a term of the Shareholder Agreement that the AOG Board of Directors shall consist of a minimum of five and a maximum of nine directors, with the present number of directors set at seven. The Shareholder Agreement provides that Unitholders are entitled to select a majority of the AOG Board of Directors. Under the terms of the Shareholder Agreement, the Manager has the right to designate two directors to be elected to the AOG Board of Directors.

The Manager and the Trust are responsible for ensuring compliance with the continuous disclosure obligations under all applicable securities legislation. The Manager has been indemnified by AOG and the Trust in respect of damages suffered relating to the performance of services under the Management Agreement provided that the Manager is in compliance with the standard of care described below, and any of its directors, officers or employees have been indemnified by AOG and the Trust provided that such person shall not be found to be liable for or guilty of wilful misfeasance, bad faith, gross negligence or reckless disregard of his or her duty to AOG or the Trust. In exercising its powers and discharging its duties under the Management Agreement, the Manager is required to exercise that degree of care, diligence and skill that a reasonably-prudent operator and manager in respect of oil and gas properties in western Canada and a manager of a publicly-traded reporting issuer, having responsibility for the subject management, advisory and administrative services, would exercise in comparable circumstances. ACQUISITION AND DISPOSITION STRATEGY The strategy employed by the Manager is to maintain the level of production of oil and natural gas from AOG's existing properties and to supplement production by reserve acquisitions. To maintain production, capital 45 expenditures are focused on development activity as opposed to exploration. Exploration properties are generally sold, farmed out or developed using third party resources. Reserve replacement and additions are achieved through development activity and acquisitions. In addition, as part of the services to be provided by the Manager to AOG and the Trust, the Manager may recommend that AOG enter into agreements to dispose of Oil and Natural Gas Properties and make farmouts and other dispositions of such properties. Approval by the AOG Board of Directors of any acquisitions or dispositions is required where the properties being acquired or disposed of have a purchase price or proceeds in excess of $2,000,000. COMPENSATION AND TERM In its role under the Management Agreement as manager and administrator of us and AOG, the Manager receives the following: 1. a fee in an amount equal to 1.5% of Operating Cash Flow, such amount to be calculated as at the end of each calendar quarter or portion thereof, if applicable, and paid on the 60th day following any such calendar quarter, or, if such day is not a Business Day, on the next Business Day; and 2. a fee in an amount equal to 10% of the Total Return Amount (which means, in respect of any Return Period, an amount equal to the Total Return Percentage minus 8% if the Return Period is a full calendar year, and adjusted appropriately should the Return Period be less than a full calendar year, multiplied by the Market Capitalization for that Return Period), such amount to be calculated as at the end of each Return Period and paid on the 15th day following the end of each such Return Period, or, if such day is not a Business Day, on the next Business Day. In addition, the Manager has the option (subject to any necessary regulatory approval) of receiving all or part of the fee provided in paragraph 2 above in Trust Units at the Unit Market Price calculated as at the end of the relevant period. The Manager representatives who act as employees or officers of AOG are entitled to participate in any benefit plans in place for AOG employees (including under any incentive plan) and are entitled to industry-competitive salaries (as approved by the AOG Board of Directors) for acting in such capacity. The Manager does not receive any acquisition or disposition fees. It is the intention of the Manager that the management fees referred to in paragraphs 1 and 2 above (collectively, the "MANAGEMENT FEES") will fund all employee bonuses and incentive plans. Effective December 30, 2005, such fees are allocated by the Manager, subject to the discretion of the Manager, on the following basis: Manager Operating Fee 60% Termination Fee 60% Performance Fee 40% Employees of AOG Operating Fee 40% Termination Fee 40% Performance Fee 60% The allocation of the Management Fees and the Termination Fees (as defined below) amongst the employees of AOG will be based upon the recommendations of the Manager as approved by the AOG Board of Directors. The initial term of the Management Agreement was for 3 years, and on each anniversary date of the Management Agreement it automatically renews on an "evergreen" basis for additional one-year periods, provided that the AOG Board of Directors has not provided notice to the Manager prior to any such renewal that such renewal shall not occur. In all instances of termination (except where the Management Agreement terminates at the end of the term), a termination fee ("TERMINATION FEES") equal to the Management Fees paid for the immediately-prior 2 1/2 years shall be payable. 46 In addition, the Manager is entitled to reimbursement, by us and AOG, of General and Administrative Costs and expenses related to the Manager's performance under the Management Agreement, other than costs related solely to the Manager and costs related to employee bonuses and incentive plans. CONFLICTS OF INTEREST The executive officers of the Manager have extensive experience in the oil and gas business and in the management of private and public entities. As a result, certain of the directors, officers and employees of the Manager, and certain of the consultants retained by the Manager, from time to time, may also be directors, officers and employees of affiliates of the Manager or may be consultants retained by affiliates of the Manager.

The Audit Committee has approved the provision of a specified list of audit and permitted non-audit services that the audit committee believes to be typical, reoccurring or otherwise likely to be provided by KPMG LLP during the current fiscal year. The list of services is sufficiently detailed as to the particular services to be provided to ensure that the audit committee knows precisely what services it is being asked to pre-approve and it is not necessary for any member of management to make a judgment as to whether a proposed service fits within pre-approved services. AUDIT COMMITTEE CHARTER The following is a summary of our Audit Committee Charter which was originally approved by the AOG Board of Directors on April 30, 2002 and amended in April 2003, April 2004, June 2005, August 2005, October 2005 and March 2006: PURPOSE The primary function of the Audit Committee is to assist the Board of Directors (the "Board of Directors" or "Board") of Advantage Oil & Gas Ltd. ("AOG") in fulfilling its responsibilities by reviewing: the financial reports and other financial information provided by Advantage Energy Income Fund (the "Trust") to any governmental body or the public; the Trust's systems of internal controls regarding finance, accounting, legal compliance and ethics that management and the Board have established; and the Trust's auditing, accounting and financial reporting processes generally. Consistent with this function, the Audit Committee should endeavour to encourage continuous improvement of, and should endeavour to foster adherence to, the Trust's policies, procedures and practices at all levels. In performing its duties, the external auditor is to report directly to the Audit Committee. The Audit Committee's primary objectives are: 1. To assist directors meet their responsibilities (especially for accountability) in respect of the preparation and disclosure of the financial statements of the Trust and related matters; 2. To provide better communication between directors and external auditors; 3. To assist the Board's oversight of the auditor's qualifications and independence; 4. To assist the Board's oversight of the credibility, integrity and objectivity of financial reports; 5. To strengthen the role of the outside directors by facilitating discussions between directors on the Audit Committee, management and external auditors; 6. To assist the Board's oversight of the performance of Corporation's internal audit function and independent auditors; and 7. To assist the Board's oversight of the Corporation's compliance with legal and regulatory requirements. COMPOSITION The Audit Committee shall be comprised of three or more directors as determined by the Board of Directors, none of whom are members of management of AOG, the Trust or Advantage Investment Management Ltd. and all of whom are "independent" (as such term is defined in (a) Multilateral Instrument 52-110 - -- Audit Committees ("MI 52-110") and (b) Section 303A.02 of the Corporate Governance Rules of the New York Stock Exchange). All of the members of the Audit Committee shall be "financially literate". The Board of Directors has adopted the definition for "financial literacy" used in MI 52-110, which definition is set forth in Schedule "A" attached hereto. Audit Committee members may enhance their familiarity with finance and accounting by participating in educational programs conducted by the Trust or an outside consultant. In addition, at least one member of the Audit Committee must have accounting or related financial management expertise, as the Corporation's Board of Directors interprets such qualification in its business judgment. The members of the Audit Committee shall be elected by the Board of Directors at the annual organizational meeting of the Board of Directors and remain as members of the Audit Committee until their successors shall be duly elected 54 and qualified. Unless a Chair is elected by the full Board of Directors, the members of the Audit Committee may designate a Chair by majority vote of the full Audit Committee membership. In connection with the election of the members of the Audit Committee, the Board will determine whether any proposed nominee for the Audit Committee serves on the Audit Committees of more than three public companies. To the extent that any proposed nominee of the Corporation serves on the Audit Committees of more than three public companies, the Board will make a determination as to whether such simultaneous services would impair the ability of such member to effectively serve on the Corporation's Audit Committee and will disclose such determination in the Corporation's annual information circular and annual report on Form 40-F filed with the Securities and Exchange Commission. MEETINGS The Audit Committee shall meet at least four times annually, or more frequently as circumstances dictate. As part of its job to foster open communication, the Audit Committee should meet at least annually with management, internal auditors (if any) and the independent auditors in separate executive sessions to discuss any matters that the Audit Committee or each of these groups believe should be discussed privately. In addition, the Audit Committee or at least its Chair should meet with the independent auditors and management quarterly to review the Trust's financials consistent with Section IV.4 below. The Audit Committee should also meet with management and independent auditors on an annual basis to review and discuss annual financial statements and the management's discussion and analysis of financial conditions and results of operations. Attached as Schedule "B" is an example of an annual meeting schedule/agenda. A quorum for meetings of the Audit Committee shall be a majority of its members, and the rules for calling, holding, conducting and adjourning meetings of the Audit Committee shall be the same as those governing the Board.

AUDIT SERVICE FEES AUDITOR SERVICES FEES The following table discloses fees billed to us by our auditors, KPMG LLP. - ------------------------------------------------------------------------------------------------------------------------------- TYPE OF SERVICE PROVIDED 2005 2004 - ------------------------------------------------------------------------------------------------------------------------------- Audit Fees (these services included prospectus work and audit or review of financials $269,000 $244,500 forming part of such prospectus and U.S. GAAP reconciliation matters) Audit-Related Fees (these services included French translation in connection with $30,000 $51,000 prospectus offerings) Tax Fees (these services included review/completion of tax returns and general tax $21,725 $26,497 consultations) RISK FACTORS The following is a summary of certain risk factors relating to the business of AOG and the Trust. The following information is a summary only of certain risk factors and is qualified in its entirety by reference to, and must be read in conjunction with, the detailed information appearing elsewhere in this annual information form. 58 DEPENDENCE ON AOG We are an open-ended, limited purpose trust which will be entirely dependent upon the operations and assets of AOG through our ownership of the Common Shares, the Notes and the Royalty. Accordingly, the cash distributions to our Unitholders will be dependent upon the ability of AOG to meet its interest and principal repayment obligations under the Notes to declare and pay dividends on the Common Shares, and to pay the Royalty. AOG's income will be received from the production of oil and natural gas from AOG's existing Canadian resource properties and will be susceptible to the risks and uncertainties associated with the oil and natural gas industry generally. AOG is generally not involved in the exploration for oil and natural gas. As a result, if the oil and natural gas reserves associated with AOG's Canadian resource properties are not supplemented through additional development or the acquisition of additional Oil and Natural Gas Properties, the ability of AOG to meet its obligations to us may be adversely affected. OIL AND NATURAL GAS PRICES AOG's results of operations and financial condition and the monthly cash distributions we pay to Unitholders are highly dependent upon the prices received for AOG's oil and natural gas production. Oil and natural gas prices can fluctuate widely on a month-to-month basis in response to a variety of factors that are beyond the control of us and AOG. These factors include, among others: o global energy policy, including the ability of OPEC to set and maintain production levels and prices for oil; o political conditions throughout the world, including the risk of hostilities in the Middle East and global terrorism; o worldwide economic conditions; o weather conditions; o the supply and price of foreign oil and natural gas; o the level of consumer demand; o the price and availability of alternative fuels; o the proximity to, and capacity of, transportation facilities; o the effect of worldwide energy conservation measures; and o government regulations. Declines in oil or natural gas prices will have an adverse effect upon our operations, financial condition, reserves and ultimately on our ability to pay distributions to Unitholders. We may manage the risk associated with changes in commodity prices by entering into oil or natural gas price hedges. If we hedge our commodity price exposure, we will forego the benefits it would otherwise experience if commodity prices were to increase. In addition, commodity hedging activities could expose us to losses. To the extent that we engage in risk management activities related to commodity prices, we will be subject to credit risks associated with counterparties with which we contract. Oil prices were relatively high throughout 2005 averaging US$56.61 WTI as compared to an average of US$41.43 WTI in 2004, an increase of 37%. AECO monthly index prices averaged $8.49/Mcf in 2005 as compared to $6.79/Mcf in 2004, an increase of 25%. The price of oil and natural gas will fluctuate and price and demand are factors beyond our control. Such fluctuations will have a positive or negative effect upon the revenue to be received by it. Such fluctuations will also have an effect upon the acquisition costs of any future Oil and Natural Gas Properties that we may acquire. As well, cash distributions from us will be highly sensitive to the prevailing price of crude oil and natural gas. EXPLOITATION AND DEVELOPMENT Exploitation and development risks are due to the uncertain results of searching for and producing oil and natural gas using imperfect scientific methods. These risks are mitigated by using highly skilled staff, focusing exploitation efforts in areas in which we have existing knowledge and expertise or access to such expertise, using up-to-date technology to enhance methods, and controlling costs to maximize returns. Advanced oil and natural 59 gas related technologies such as three-dimensional seismography, reservoir simulation studies and horizontal drilling have been and will be used by us to improve our ability to find, develop and produce oil and natural gas. OPERATING COSTS AND PRODUCTION DECLINES Higher operating costs for the underlying properties of AOG will directly decrease the amount of cash flow received by us and, therefore, may reduce distributions to our Unitholders. Electricity, chemicals, supplies, reclamation and abandonment and labour costs are a few of AOG's operating costs that are susceptible to material fluctuation. The level of production from AOG's existing properties may decline at rates greater than anticipated due to unforeseen circumstances, many of which are beyond AOG's control. A significant decline in production could result in materially lower revenues and cash flow and, therefore, could reduce the amount available for distributions to Unitholders. OPERATIONS AOG's operations are subject to all of the risks normally incident to the operation and development of Oil and Natural Gas Properties and the drilling of oil and natural gas wells, including encountering unexpected formations or pressures, blow-outs, craterings and fires, all of which could result in personal injuries, loss of life and damage to the property of AOG and others. AOG has both safety and environmental policies in place to protect its operators and employees, as well as to meet the regulatory requirements in those areas where it operates. In addition, AOG has liability insurance policies in place, in such amounts as it considers adequate, however, it will not be fully insured against all of these risks, nor are all such risks insurable. Costs incurred to repair any of such damage or pay any of such liabilities will reduce Royalty Income. Continuing production from a property, and, to some extent the marketing of production therefrom, are largely dependent upon the ability of the operator of the property. To the extent the operator fails to perform these functions properly, revenue may be reduced. Payments from production generally flow through the operator and there is a risk of delay and additional expense in receiving such revenues if the operator becomes insolvent. Although satisfactory title reviews are generally conducted in accordance with industry standards, such reviews do not guarantee or certify that a defect in the chain of title may not arise to defeat the claim of AOG to certain Properties. A reduction of the income from the Royalty could result in such circumstances. MARKETING The marketability and price of oil and natural gas that may be acquired or discovered by us will be affected by numerous factors beyond our control. These factors include demand for oil and natural gas, market fluctuations, the proximity and capacity of oil and natural gas pipelines and processing equipment and government regulations, including regulations relating to environmental protection, royalties, allowable production, pricing, importing and exporting of oil and natural gas. CAPITAL INVESTMENT To the extent that AOG uses cash flow to finance acquisitions, development costs and other significant expenditures, the net cash flow of the Trust will be reduced. Hence, the timing and amount of capital expenditures may affect the amount of net cash flow available to us and, as a consequence, the amount of cash available to distribute to Unitholders. Therefore, distributions may be reduced, or even eliminated, at times when significant capital or other expenditures are made. The AOG Board of Directors has the discretion to determine the extent to which cash flow will be allocated to the payment of debt service charges as well as the repayment of outstanding debt, including under the credit facility. As a consequence, the amount of funds retained by AOG to pay debt services charges or reduce debt will reduce the amount of cash distributed to Unitholders during those periods in which funds are so retained. ASSESSMENTS OF VALUE OF ACQUISITIONS Acquisitions of resource issuers and resource assets will be based in large part upon engineering and economic assessments made by independent engineers. These assessments will include a series of assumptions regarding such factors as recoverability and marketability of oil and gas, future prices of oil and 60 gas and operating costs, future capital expenditures and royalties and other government levies which will be imposed over the producing life of the reserves. Many of these factors are subject to change and are beyond our control. In particular, the prices of and markets for resource products may change from those anticipated at the time of making such assessment. In addition, all such assessments involve a measure of geologic and engineering uncertainty which could result in lower production and reserves than anticipated. Initial assessments of acquisitions may be based upon reports by a firm of independent engineers that are not the same as the firm that we use for our year end reserve evaluations. Because each of these firms may have different evaluation methods and approaches, these initial assessments may differ significantly from the assessments of the firm used by us. Any such instance may offset the return on and value of the Trust Units. DEBT SERVICE AOG has credit facilities in the amount of $355,000,000. Variations in interest rates and scheduled principal repayments could result in significant changes in the amount required to be applied to debt service before payment of any amounts to us. Although it is believed that the bank line of credit is sufficient, there can be no assurance that the amount will be adequate for the financial obligations of AOG or that additional funds can be obtained. The lenders have been provided with security over substantially all of the assets of AOG. If AOG becomes unable to pay its debt service charges or otherwise commits an event of default such as bankruptcy, the lenders may foreclose on or sell the Properties free from or together with the Royalty. The payment of interest and principal on debt may also result in us or our subsidiaries having taxable income and cash taxes payable as taxable income would no longer be reduced by royalty payments at the time debt repayment occurs. PRIOR RANKING INDEBTEDNESS; ABSENCE OF COVENANT PROTECTION The Debentures will be subordinate to all Senior Indebtedness and to any indebtedness of our creditors. The payment of principal and interest on the Debentures will be subordinated to the Senior Indebtedness of us and to indebtedness of our trade creditors. The Debentures will also be effectively subordinate to claims of creditors of our subsidiaries except to the extent we are a creditor of such subsidiaries ranking at least pari passu with such other creditors. The Indentures will not limit the ability of us to incur additional liabilities (including Senior Indebtedness) or to make distributions, except, in respect of distributions, where an Event of Default has occurred or would occur and such default has not been cured or waived. The Indentures do not contain any provision specifically intended to protect holders of the Debentures in the event of a future leveraged transaction involving Advantage. However, the Indentures, among other things, restrict our level of indebtedness, provides operating investment guidelines, mandates the making of distributions and specify the nature of our business. ENVIRONMENTAL CONCERNS The oil and natural gas industry is subject to environmental regulation pursuant to local, provincial and federal legislation. A breach of such legislation may result in the imposition of fines or issuance of clean-up orders in respect of AOG or the Properties. Such legislation may be changed to impose higher standards and potentially more costly obligations on AOG. Although AOG has established a reclamation fund for the purpose of funding its currently estimated future environmental and reclamation obligations based upon its current knowledge, there can be no assurance that we will be able to satisfy its actual future environmental and reclamation obligations. Although AOG maintains insurance coverage considered to be customary in the industry, it is not fully insured against certain environmental risks, either because such insurance is not available, or because of high premium costs. In particular, insurance against risks from environmental pollution occurring over time (compared to sudden and catastrophic damages) is not available. Accordingly, AOG's properties may be subject to liability due to hazards which cannot be insured against, or have not been insured against due to prohibitive premium costs or for other reasons. In such an event, these environmental obligations will be funded out of AOG's cash flow and could therefore reduce distributable income payable to Unitholders. Additionally, the potential impact on our operations and business of the December 1997 Kyoto Protocol, which has now been ratified by Canada, with respect to instituting reductions of greenhouse gases is difficult to quantify at this time as specific measures for meeting Canada's commitments have not been developed. 61 UNFORESEEN TITLE DEFECTS Although title reviews are generally conducted prior to any purchase of resource issuers or resource assets, such reviews do not guarantee that an unforeseen defect in the chain of title will not arise to defeat AOG's title to certain assets. A reduction of the distributable cash flow of the Trust and possible reduction of capital could result from such defects. Any site reclamation or abandonment costs actually incurred in the ordinary course of business in a specific period will be funded out of cash flow and, therefore, will reduce the amounts available for distribution to Unitholders. Should we be unable to fully fund the cost of remedying an environmental problem, it might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy. DELAY IN CASH DISTRIBUTIONS In addition to the usual delays in payment by purchasers of oil and natural gas to the operators of the Properties, and by the operator to the Manager or AOG, payments between any of such parties may also be delayed by restrictions imposed by lenders, accounting delays, delays in the sale or delivery of products, delays in the connection of wells to a gathering system, blowouts or other accidents, recovery by the operator of expenses incurred in the operation of the Properties, or the establishment by the operator of reserves for such expenses. Any of these delays could adversely affect distributions to Unitholders. FOREIGN CURRENCY EXCHANGE RATES AND INTEREST RATES World oil prices are quoted in United States dollars and the price received by Canadian producers is therefore affected by the $Cdn/$US exchange rate that may fluctuate over time. A material increase in the value of the Canadian dollar, which occurred in 2005, negatively impacted our net production revenue and may affect the future value of our reserves as determined by independent evaluations at this time. The Canadian dollar strengthened in 2005 to average $0.83 US/Cdn compared to $0.77 US/Cdn in 2004. The impact is reduced to the extent that we have engaged in, or in the future will engage in risk management activities related to commodity prices and foreign exchange rates. We will be subject to unfavourable price changes and credit risks associated with the counterparties with which it contracts. We have not entered into any foreign exchange contracts at this time. Variations in interest rates could result in a significant increase in the amount we pay to service debt which may result in a decrease in distributions to Unitholders, as well as impact the market price of the Trust Units on the TSX. RELIANCE UPON THE MANAGER AND SENIOR EXECUTIVES OF AOG Unitholders will be dependent upon the management of the Manager and AOG in respect of the administration and management of all matters relating to the Properties, the Royalty, the Trust and the Trust Units. The loss of the services of key individuals who currently comprise our management team could have a detrimental effect upon us. Investors who are not willing to rely on the management of the Manager and AOG should not invest in the Trust Units. RESERVES The value of the Trust Units will depend upon, among other things, the reserves attributable to our properties. Estimating reserves is inherently uncertain. Ultimately, actual production, revenues and expenditures for our properties will vary from estimates and those variations could be material. The reserve and cash flow information contained in this annual information form represent estimates only. Reserves and estimated future net cash flow from our properties have been independently evaluated at the dates indicated by independent oil and gas reservoir engineering firms. These firms consider a number of factors and make assumptions when estimating reserves. These factors and assumptions include: o historical production in the area compared with production rates from similar producing areas; o the assumed effect of governmental regulation; o assumptions about future commodity prices, production and development costs, severance and excise taxes, and capital expenditures; o initial production rates; 62 o production decline rates; o ultimate recovery of reserves; o timing and amount of capital expenditures; o marketability of production; o future prices of oil and natural gas; o operating costs and royalties; and o other government levies that may be imposed over the producing life of reserves. These factors and assumptions were based upon prices at the date the relevant evaluations were prepared. If these factors and assumptions prove to be inaccurate, actual results may vary materially from the reserve estimates. Many of these factors are subject to change and are beyond our control. For example, evaluations are based in part upon the assumed success of exploitation activities intended to be undertaken in future years. Actual reserves and estimated cash flows will be less than those contained in the evaluations to the extent that such exploitation activities do not achieve the level of success assumed in the evaluations. Furthermore, cash flows may differ from those contained in the evaluations depending upon whether capital expenditures and operating costs differ from those estimated in the evaluations. DEPLETION OF RESERVES We have certain unique attributes that differentiate it from other oil and gas industry participants. Distributions of distributable income in respect of Properties, absent commodity price increases or cost effective acquisition and development activities will decline over time in a manner consistent with declining production from typical oil, natural gas and natural gas liquids reserves. AOG will not be reinvesting cash flow in the same manner as other industry participants. Accordingly, absent capital injections, AOG's initial production levels and reserves will decline. AOG's future oil and natural gas reserves and production, and therefore its cash flows, will be highly dependent upon AOG's success in exploiting its reserve base and acquiring additional reserves. Without reserve additions through acquisition or development activities, AOG's reserves and production will decline over time as reserves are exploited. To the extent that external sources of capital, including the issuance of additional Trust Units, become limited or unavailable, AOG's ability to make the necessary capital investments to maintain or expand its oil and natural gas reserves will be impaired. To the extent that AOG is required to use cash flow to finance capital expenditures or property acquisitions, the level of distributable income will be reduced. There can be no assurance that we will be successful in developing or acquiring additional reserves on terms that meet our investment objectives. RELIANCE UPON THIRD PARTY OPERATORS Continuing production from a property and marketing of product produced from the property are dependent to a large extent upon the ability of the operator of the property. We currently operate properties that represent approximately 85% of our total daily production. To the extent the operator fails to perform these functions properly or becomes insolvent, revenue may be reduced. ENFORCEMENT OF OPERATING AGREEMENTS Operations of the wells on properties not operated by us are generally governed by operating agreements, which typically require the operator to conduct operations in a good and workmanlike manner. Operating agreements generally provide, however, that the operator will have no liability to the other non-operating working interest owners for losses sustained or liabilities incurred, except such as may result from gross negligence or wilful misconduct. In addition, third-party operators are generally not fiduciaries with respect to us or our Unitholders. As an owner of working interests in properties we do not operate, we will generally have a cause of action for damages arising from a breach of such duty. Although not established by definitive legal precedent, it is unlikely that the Trust or Unitholders would be entitled to bring suit against third-party operators to enforce the terms of the operating agreements; thus, Unitholders will be dependent upon us, as owner of the working interest, to enforce such rights. 63 CHANGES IN TAX AND OTHER LAWS MAY ADVERSELY AFFECT UNITHOLDERS. Income tax laws, or other laws or government incentive programs relating to the oil and gas industry, such as the treatment of mutual fund trusts and resource allowance, may in the future be changed or interpreted in a manner that adversely affects us and our Unitholders. In particular, generally speaking, the Tax Act provides that a trust will permanently lose its "mutual fund trust" status (which is essential to the income trust structure) if it is established or maintained primarily for the benefit of non-residents of Canada (which is generally interpreted to mean that the majority of unitholders must not be non-residents of Canada), unless at all times after February 21, 1990, "all or substantially all" of the trust's property consisted of property other than taxable Canadian property (the "TCP EXCEPTION"). Based on the most recent information obtained by us through our transfer agent and financial intermediaries, in February 2006 an estimated 60% of our issued and outstanding Trust Units were held by non-residents of Canada (as defined in the Tax Act) at that time. We are currently able to take advantage of the TCP Exception, and as a result, the Trust Indenture does not currently have a specific limit on the percentage of Trust Units that may be owned by non-residents. On March 23, 2004 the Canadian federal government announced proposed changes to the Tax Act which would have effectively eliminated, over a period of time, the TCP Exception currently relied on by us to maintain our mutual fund trust status, and, if implemented, would require us to comply with the requirement that it "not be maintained primarily for the benefit of non-residents". In response to submissions from and discussions with stakeholders, the Canadian federal government suspended the implementation of those proposed amendments. The Canadian Minister of Finance indicated in the February 23, 2005 federal budget that further consultations would be pursued with stakeholders on taxation issues related to income trusts and other flow-through entities. On September 8, 2005, the Canadian Department of Finance released a discussion paper on these matters and invited interested parties to make submissions to the Department of Finance. On November 23, 2005, the former Canadian Minister of Finance issued a news release announcing that no change would be made to the tax treatment of income trusts in Canada and calling an end to the consultation process initiated in September 2005. Notwithstanding the above, there is no assurance that the TCP Exception will continue to be available to the Trust or that the Canadian federal government will not introduce new changes or proposals to tax regulations directed at non-resident ownership which, given our level non-resident ownership, may result in us losing our mutual fund trust status or could otherwise detrimentally affect us and the market price of the Trust Units. We intend to continue to take the necessary measures in order to ensure that we continue to qualify as a mutual fund trust under the Tax Act. There would be material adverse consequences if we lost our status as a mutual fund trust under Canadian tax laws. See "Changes in Legislation - Material Adverse Tax Consequences to Loss of Mutual Fund Trust Status". However, we may not be able to take steps necessary to ensure that we maintain our mutual fund trust status. Even if we are successful in taking such measures, these measures could be adverse to certain holders of Trust Units, particularly "non-residents" of Canada (as defined in the Tax Act). There can be no assurance that such circumstances would not detrimentally affect the market price of the Trust Units. Additionally, legislation may be implemented to limit the investment in income funds and royalty trusts by certain investors or to change the manner in which these entities are taxed. Tax authorities having jurisdiction over us or our Unitholders may disagree with how we calculate our income for tax purposes or could change administrative practices to our detriment or the detriment of our Unitholders. CHANGES IN LEGISLATION - MATERIAL ADVERSE TAX CONSEQUENCES TO LOSS OF MUTUAL FUND TRUST STATUS There can be no assurance that the treatment of mutual fund trusts will not be changed in a manner adversely affecting Unitholders. If we cease to qualify as a "mutual fund trust" under the Tax Act, the Trust Units will cease to be qualified investments for registered retirement savings plans, registered education savings plans, deferred profit sharing plans and registered retirement income funds. Income tax laws, or other laws or government incentive programs relating to the oil and gas industry, such as the treatment of mutual fund trusts and resource taxation, may in the future be changed or interpreted in a manner 64 that adversely affects us and our Unitholders. Tax authorities having jurisdiction over the Trust or the Unitholders may disagree with how we calculate our income for tax purposes or could change administrative practises to the detriment of us or the detriment of our Unitholders. We expect that it will continue to qualify as a mutual fund trust for purposes of the Tax Act. We may not, however, always be able to satisfy any future requirements for the maintenance of mutual fund trust status. Should the status of the Trust as a mutual fund trust be lost or successfully challenged by a relevant tax authority, certain adverse consequences may arise for us and our Unitholders. Some of the significant consequences of losing mutual fund trust status are as follows: o We would be taxed on certain types of income distributed to Unitholders, including income generated by the royalties held by us. Payment of this tax may have adverse consequences for some Unitholders, particularly Unitholders that are not residents of Canada and residents of Canada that are otherwise exempt from Canadian income tax. o We would cease to be eligible for the capital gains refund mechanism available under Canadian tax laws if it ceased to be a mutual fund trust. o Trust Units held by Unitholders that are not residents of Canada would become taxable Canadian property. These non-resident holders would be subject to Canadian income tax on any gains realized on a disposition of Trust Units held by them. o Trust Units would not constitute qualified investments for registered retirement savings plans ("RRSPs"), registered retirement income funds ("RRIFs"), registered education savings plans ("RESTs") or deferred profit sharing plans ("DPSPs"). If, at the end of any month, one of these exempt plans holds Trust Units that are not qualified investments, the plan must pay a tax equal to 1% of the fair market value of the Trust Units at the time the Trust Units were acquired by the exempt plan. An RRSP or RRIF holding non-qualified Trust Units would be subject to taxation on income attributable to the Trust Units. If an RESP holds non-qualified Trust Units, it may have our registration revoked by the Canada Customs and Revenue Agency. In addition, we may take certain measures in the future to the extent it believes necessary to ensure that we maintain our status as a mutual fund trust. These measures could be adverse to certain holders of Trust Units. INVESTMENT ELIGIBILITY We will endeavour to ensure that the Trust Units continue to be qualified investments for registered retirement savings plans, registered education savings plans, deferred profit sharing plans and registered retirement income funds. The Tax Act imposes penalties for the acquisition or holding of non-qualified or ineligible investments and there is no assurance that the conditions prescribed for such qualified or eligible investments will be adhered to at any particular time. NATURE OF TRUST UNITS The Trust Units do not represent a traditional investment in the oil and natural gas sector and should not be viewed by investors as shares in AOG. The Trust Units represent a fractional interest in the Trust. As holders of Trust Units, Unitholders will not have the statutory rights normally associated with ownership of shares of a corporation including, for example, the right to bring "oppression" or "derivative" actions. Our primary assets will be the Notes, the Common Shares, the Royalty and other investments in securities. The price per Trust Unit is a function of anticipated distributable income, the Properties acquired by AOG, and the Manager's ability to effect long-term growth in our value. The market price of the Trust Units will be sensitive to a variety of market conditions including, but not limited to, interest rates and our ability to acquire suitable oil and natural gas properties. Changes in market conditions may adversely affect the trading price of the Trust Units. The Trust Units are also unlike conventional debt instruments in that there is no principal amount owing to Unitholders. The Trust Units will have minimal value when reserves from our properties can no longer be economically produced or marketed. Unitholders will only be able to obtain a return of the capital 65 they invested during the period when reserves may be economically recovered and sold. Accordingly, the distributions received over the life of the investment may not be equal to or greater than the initial capital investment. THE TRUST UNITS ARE NOT "DEPOSITS" WITHIN THE MEANING OF THE CANADA DEPOSIT INSURANCE CORPORATION ACT (CANADA) AND ARE NOT INSURED UNDER THE PROVISIONS OF THAT ACT OR ANY OTHER LEGISLATION. FURTHERMORE, THE TRUST IS NOT A TRUST COMPANY AND, ACCORDINGLY, IS NOT REGISTERED UNDER ANY TRUST AND LOAN COMPANY LEGISLATION AS IT DOES NOT CARRY ON OR INTEND TO CARRY ON THE BUSINESS OF A TRUST COMPANY. NET ASSET VALUE The net asset value of our assets from time to time will vary depending upon a number of factors beyond the control of management, including oil and gas prices. The trading prices of the Trust Units from time to time is also determined by a number of factors which are beyond the control of management and such trading prices may be greater than the net asset value of our assets. ADDITIONAL FINANCING In the normal course of making capital investments to maintain and expand our oil and gas reserves, additional Trust Units are issued from treasury which may result in a decline in production per Trust Unit and reserves per Trust Unit. Additionally, from time to time we issue Trust Units from treasury in order to reduce debt and maintain a more optimal capital structure. To the extent that external sources of capital, including the issuance of additional Trust Units, become limited or unavailable, our ability and AOG's ability to make the necessary capital investments to maintain or expand our oil and gas reserves will be impaired. To the extent that the Trust and AOG are required to use cash flow to finance capital expenditures or property acquisitions or to pay debt service charges or to reduce debt, the level of distributable income will be reduced. COMPETITION There is strong competition relating to all aspects of the oil and gas industry. There are numerous trusts in the oil and gas industry, who are competing for the acquisitions of properties with longer life reserves and properties with exploitation and development opportunities. As a result of such increasing competition, it will be more difficult to acquire reserves on beneficial terms. The Trust and AOG also compete for reserve acquisitions and skilled industry personnel with a substantial number of other oil and gas companies, many of which have significantly greater financial and other resources than the Trust and AOG. RETURN OF CAPITAL Trust Units will have no value when reserves from the Properties can no longer be economically produced and, as a result, cash distributions do not represent a "yield" in the traditional sense and are not comparable to bonds or other fixed yield securities, where investors are entitled to a full return of the principal amount of debt on maturity in addition to a return on investment through interest payments. Distributions represent a blend of a return of Unitholders' initial investment and a return on Unitholders' initial investment. Unitholders have a limited right to require us to repurchase their Trust Units, which is referred to as a redemption right. See "Information Relating to the Trust - Right of Redemption". It is anticipated that the redemption right will not be the primary mechanism for Unitholders to liquidate their investment. The right to receive cash in connection with a redemption is subject to limitations. Any securities which may be distributed IN SPECIE to Unitholders in connection with a redemption may not be listed on any stock exchange and a market may not develop for such securities. In addition, there may be resale restrictions imposed by law upon the recipients of the securities pursuant to the redemption right. REDEMPTION RIGHT It is anticipated that the redemption right will not be the primary mechanism for Unitholders to liquidate their investments. Long Term Notes or Redemption Notes which may be distributed IN SPECIE to Unitholders in connection with a redemption will not be listed on any stock exchange and no established market 66 is expected to develop for such Long Term Notes or Redemption Notes. Cash redemptions are subject to limitations. See "Additional Information Respecting Advantage Energy Income Fund - Redemption Right". UNITHOLDER LIMITED LIABILITY The Trust Indenture provides that no Unitholder will be subject to any liability in connection with us or our affairs or obligations and, in the event that a court determines that Unitholders are subject to any such liabilities, the liabilities will be enforceable only against, and will be satisfied only out of, such Unitholder's share of our assets. The Trust Indenture provides that all written instruments signed by or on behalf of us must contain a provision to the effect that such obligation will not be binding upon Unitholders personally. Notwithstanding the provisions of the Trust Indenture and the fact that Alberta (our governing jurisdiction) has adopted legislation purporting to limit trust unitholder liability, because of uncertainties in the law relating to investment trusts, there is a risk that a Unitholder could be held personally liable for obligations of the Trust in respect of contracts or undertakings which the Trust enters into and for certain liabilities arising otherwise than out of contracts including claims in tort, claims for taxes and possibly certain other statutory liabilities. The possibility of any personal liability of this nature arising is considered unlikely. FUTURE DILUTION One of our objectives is to continually add to our reserves through acquisitions and through development, and because we does not reinvest our cash flow, our success is in part dependent upon our ability to raise capital from time to time. Holders of Trust Units may also suffer dilution in connection with future issuances of Trust Units, whether issued pursuant to a financing or acquisition or otherwise. REGULATORY MATTERS Our operations are subject to a variety of federal and provincial laws and regulations, including laws and regulations relating to the protection of the environment. THE ECONOMIC IMPACT ON ADVANTAGE OF CLAIMS OF ABORIGINAL TITLE IS UNKNOWN. Aboriginal people have claimed aboriginal title and rights to a substantial portion of western Canada. We are unable to assess the effect, if any, that any such claim would have on our business and operations. EXPANSION OF OPERATIONS The operations and expertise of our management are currently focused on conventional oil and gas production and development in the Western Canadian Sedimentary Basin. In the future, we may acquire oil and gas properties outside this geographic area. In addition, the Trust Indenture does not limit our activities to oil and gas production and development, and we could acquire other energy related assets, such as oil and natural gas processing plants or pipelines, or an interest in an oil sands project. Expansion of our activities into new areas may present new additional risks or alternatively, may significantly increase the exposure to one or more of the present risk factors which may result in our future operational and financial conditions being adversely affected. CONFLICTS OF INTEREST The directors and officers of the Corporation are engaged in and will continue to be engaged in other activities in the oil and natural gas industry and, as a result of these and other activities, the directors and officers of the Corporation may become subject to conflicts of interest. The ABCA provides that in the event that a director has an interest in a contract or proposed contract or agreement, the director shall disclose his interest in such contract or agreement and shall refrain from voting on any matter in respect of such contract or agreement unless otherwise provided under the ABCA. To the extent that conflicts of interest arise, such conflicts will be resolved in accordance with the provisions of the ABCA. 67 CHANGES IN ACCOUNTING STANDARDS During 2005 there were several changes to financial reporting requirements. The changes impacting us are noted below. FINANCIAL INSTRUMENTS - PRESENTATION AND DISCLOSURE Effective January 1, 2005, the Fund retroactively adopted the revised accounting standard Section 3860 "Financial Instruments - Presentation and Disclosure" as issued by the CICA. The revised standard applies to financial instruments that may be settled at the issuer's option in cash or its own equity instruments and impacts our prior accounting for convertible debentures and the performance incentive fee. We previously classified the issuance of convertible debentures and the performance fee obligation as components of equity on the basis that the obligations could be settled with the issuance of Trust Units. Interest expense and issuance costs related to the debentures were charged to accumulated income as a component of equity. Based on the revised standard, a financial instrument is presented based on the substance of the contractual arrangement regardless of the means of settlement. This results in the reclassification of convertible debentures to long-term liabilities and the performance fee to current liabilities. Additionally, a financial instrument with an embedded conversion feature must be segregated between liabilities and equity based on the relative fair market value of the liability and equity portions. Therefore, the debenture liabilities are presented at less than their eventual maturity values. The liability and equity components are further reduced for issuance costs initially incurred. The discount of the liability component as compared to maturity value is accreted by the "effective interest" method over the debenture term. As debentures are converted to Trust Units, an appropriate portion of the liability and equity components are transferred to Unitholders' capital. Interest and accretion expense on the convertible debentures are shown on the Consolidated Statements of Income. EXCHANGEABLE SHARES In March 2005, the CICA's Emerging Issues Committee amended EIC-151 "Exchangeable Securities Issued by Subsidiaries of Income Trusts". The EIC specifies the required criteria to present exchangeable shares as a component of Unitholders' equity. Exchangeable shares that do not meet both criteria are classified as either debt or non-controlling interest depending on the nature of the instrument. Prior to the amendment, Exchangeable Shares of AOG were shown as a component of Unitholders' equity. However, the Exchangeable Shares do not meet the requirements of the amended standard given that the shares are transferable, although not publicly traded. Therefore, Exchangeable Shares are now classified as non-controlling interest, outside of Unitholders' equity. The Exchangeable Shares and Trust Units are considered economically equivalent since the exchange ratio is increased on each date that a distribution is paid on the Trust Units and all shares must be exchanged for either Trust Units or cash, based on the current market price of the Trust Units. Since the Exchangeable Shares are required to be exchanged, there is no permanent non-controlling interest. As a consequence of presenting Exchangeable Shares as non-controlling interest, a corresponding expense is recorded that reflects the earnings attributable to the non-controlling interest. When Exchangeable Shares are converted to Trust Units, the carrying value of non-controlling interest on the balance sheet is reclassified to Unitholders' capital. We retroactively implemented the revised standard but there was no income impact on periods prior to 2005 given that the Exchangeable Shares were issued at the end of 2004. FINANCIAL INSTRUMENTS -- RECOGNITION AND MEASUREMENT In April 2005, a series of new accounting standards were released which established guidance for the recognition and measurement of financial instruments. These new standards include Section 1530 "Comprehensive Income", Section 3855 "Financial Instruments -- Recognition and Measurement", and Section 3865 "Hedges", in each case issued by the CICA. The new standards also resulted in a number of significant consequential amendments to other accounting standards to accommodate the new sections. The standards require all applicable financial instruments to be classified into one of several categories including: financial assets and financial liabilities held for trading, held-to-maturity investments, loans and receivables, available-for-sale financial assets, or other financial liabilities. The financial instruments are then included on an issuer's balance sheet and measured at fair value, cost or amortized value, depending on the classification. Subsequent measurement and recognition of changes in value of the financial instruments also depends on the initial classification. These standards are effective for interim and annual financial statements for fiscal years beginning on or after October 1, 2006 and must be implemented simultaneously. We have not yet assessed the full impact, if any, of these standards on the consolidated financial statements. However, we anticipate adoption of the new standards on January 1, 2007. 68 RISKS PARTICULAR TO UNITED STATES AND OTHER NON-RESIDENT UNITHOLDERS In addition to the risk factors set forth above, the following risk factors are particular to unitholders who are not residents of Canada. UNITED STATES AND OTHER NON-RESIDENT UNITHOLDERS MAY BE SUBJECT TO ADDITIONAL TAXATION. The Tax Act and the tax treaties between Canada and other countries may impose additional withholding or other taxes on the cash distributions or other property paid by us to Unitholders who are not residents of Canada, and these taxes may change from time to time. For instance, since January 1, 2005, a 15% withholding tax is applied to return of capital portion of distributions made to non-resident unitholders. THE ABILITY OF UNITED STATES AND OTHER NON-RESIDENT UNITHOLDERS INVESTORS TO ENFORCE CIVIL REMEDIES MAY BE LIMITED. We are a trust organized under the laws of Alberta, Canada, and our principal place of business is in Canada. All of the directors and officers of AOG are residents of Canada and most of the experts who provide services to us (such as its auditors and some of its independent reserve engineers) are residents of Canada, and all or a substantial portion of their assets and our assets are located within Canada. As a result, it may be difficult for investors in the United States or other non-Canadian jurisdictions (a "FOREIGN JURISDICTION") to effect service of process within such Foreign Jurisdiction upon such directors, officers and representatives of experts who are not residents of the Foreign Jurisdiction or to enforce against them judgments of courts of the applicable Foreign Jurisdiction based upon civil liability under the securities laws of such Foreign Jurisdiction, including United States federal securities laws or the securities laws of any state within the United States. In particular, there is doubt as to the enforceability in Canada against us or any of our directors, officers or representatives of experts who are not residents of the United States, in original actions or in actions for enforcement of judgments of United States courts of liabilities based solely upon the United States federal securities laws or the securities laws of any state within the United States. DISCLOSURE PURSUANT TO THE REQUIREMENTS OF THE NEW YORK STOCK EXCHANGE As a Canadian issuer listed on the New York Stock Exchange (the "NYSE"), we are not required to comply with most of the NYSE rules and listing standards and instead may comply with domestic requirements. As a foreign private issuer, we are only required to comply with three of the NYSE Rules: 1) have an audit committee that satisfies the requirements of the United States Securities Exchange Act of 1934; 2) the Chief Executive Officer must promptly notify the NYSE in writing after an executive officer becomes aware of any material non-compliance with the applicable NYSE Rules; and 3) provide a brief description of any significant differences between our corporate governance practices and those followed by U.S. companies listed under the NYSE. We have reviewed the NYSE listing standards and confirm that our corporate governance practices do not differ significantly from such standards. ADDITIONAL INFORMATION Additional information, including directors' and officers' remuneration and indebtedness, principal holders of securities and interests of insiders in material transactions, where applicable, is contained in our information circular for the most recent annual meeting of shareholders that involved the election of directors. Additional financial information is provided in our financial statements and management's discussion and analysis for the year ended December 31, 2005.
