    (1) Per unit amounts (with the exception of per unit distributions) are
        based on weighted average trust units outstanding plus trust units
        issuable for exchangeable shares. Per unit distributions are based on
        the number of trust units outstanding at each distribution record
        date.
    (2) Cash flow from operating activities is a GAAP measure. Historically,
        Management has disclosed Cash Flow as a non-GAAP measure calculated
        using cash flow from operating activities less the change in non-cash
        working capital and the expenditures on site restoration and
        reclamation as they appear on the Consolidated Statements of Cash
        Flows. Cash Flow for the third quarter of 2009 would be
        $124.8 million ($0.52 per unit) and $361.9 million ($1.54 per unit)
        year-to-date. Distributions as a percentage of Cash Flow would be 57
        per cent for the third quarter of 2009 (63 per cent year-to-date).
    (3) Net income per unit is based on net income after non-controlling
        interest divided by weighted average trust units outstanding
        (excluding trust units issuable for exchangeable shares).
    (4) Net debt excludes current unrealized amounts pertaining to risk
        management contracts and the current portion of future income taxes.
    (5) Includes other revenue.
    (6) For the third quarter of 2009, includes 0.9 million (1.1 million in
        2008) exchangeable shares exchangeable into 2.679 trust units (2.431
        in 2008) each for an aggregate 2.5 million (2.7 million in 2008)
        trust units.
    (7) Includes trust units issuable for outstanding exchangeable shares at
        period end.

    ACCOMPLISHMENTS/FINANCIAL UPDATE
    --------------------------------

    -   Production volumes for the quarter were 62,824 boe per day, a decline
        of two per cent compared to the second quarter. The Trust continues
        to expect full year average production between 63,000 and 64,000 boe
        per day.

    -   Operating costs decreased to $9.68 per boe in the quarter compared to
        $10.19 per boe in the third quarter of 2008. Total operating costs
        decreased $4.3 million, or seven per cent in the third quarter of
        2009 as compared to the third quarter of 2008. The decrease in costs
        is primarily attributed to lower power costs in 2009 as well as cost
        savings and efficiencies achieved by the operations team. The Trust
        estimates that full year 2009 operating costs will be approximately
        $243 million or approximately $10.50 per boe based on annual
        production of between 63,000 and 64,000 boe per day.

    -   Cash flow from operating activities was $125.6 million, or $0.53 per
        unit, a significant decline from the $251.4 million ($1.16 per unit)
        achieved in the comparable quarter in 2008. This decline was due to a
        49 per cent decrease in commodity prices in the third quarter of 2009
        compared to the same period in 2008. Crude oil prices strengthened
        during the third quarter compared to the first half of 2009 as the
        economy showed some positive signs of recovery. Natural gas prices
        continued to soften throughout the third quarter reaching a low of
        $1.94 per mcf, however they did begin to recover early in the fourth
        quarter. After payment of distributions the Trust was able to fund 55
        per cent of the third quarter capital program with cash flow from
        operating activities (72 per cent when including the quarterly
        proceeds from the distributions re-investment program ("DRIP")) with
        the remaining portion being funded through proceeds from property
        dispositions that were completed in the quarter.

    -   The Trust executed a $96.2 million capital expenditure program in the
        third quarter of 2009 that included: drilling 11 oil wells in the
        Ante Creek, Pembina and Goodlands areas, drilling six natural gas
        wells in the Dawson area, and spending $11 million on the new gas
        plant at Dawson. Of the wells drilled in the third quarter, two
        natural gas wells and seven oil wells were completed; as well 10
        wells were completed that were drilled in previous quarters. Included
        in the third quarter capital expenditures is a crown land acquisition
        in Pembina for $2.4 million where the Trust is planning to drill nine
        horizontal oil wells into the Cardium zone during the fourth quarter
        and into 2010. During the quarter, the Trust closed a disposition of
        non-core assets in southeast Saskatchewan for proceeds of $33.5
        million that were used to fund a portion of the third quarter capital
        expenditures. Full year capital expenditures are now expected to be
        approximately $365 million, an increase of $15 million over second
        quarter guidance as the Trust has chosen to increase capital spending
        in Alberta and British Columbia to take advantage of royalty
        incentives announced by those provinces.

    -   At September 30, 2009 the Trust had a net debt balance of $705.4
        million, approximately $680 million of unused credit available and a
        net debt to annualized year-to-date cash flow from operating
        activities of 1.5 times. At this time, the Trust is well positioned
        to finance the remainder of the 2009 capital program and the
        projected 2010 capital program.

    -   ARC plans to convert to a Corporation on January 1, 2011. The Board
        of Directors has approved the overall strategy and currently the
        detailed implementation steps are being defined.

    -   The Trust's board of directors has approved a $575 million capital
        program for 2010 that will encompass considerable growth. The program
        will include over $250 million slated for the first of many stages of
        production growth and continued expansion of the Montney assets in
        Northeast British Columbia with the remainder focused on ARC base
        development areas, exploration opportunities and enhanced oil
        recovery projects. ARC plans to drill 203 gross wells on operated
        properties and plans to participate in an additional 91 wells on
        partner operated properties. The Trust plans to finance the 2010
        capital program through a combination of cash flow, existing credit
        facilities, DRIP proceeds and potential minor assets disposition
        proceeds. Additional details can be found in the November 5, 2009
        news release titled "ARC Energy Trust Announces a $575 million
        Capital Budget for 2010" and filed on www.sedar.com.

    -   Montney Resource Play Development

        Production from the Dawson area was on budget at an average rate of
        53.3 mmcf per day throughout the third quarter. The decreased
        production rates when compared to the second quarter of 2009 were as
        a result of the planned turnaround of a third party gas plant that
        shut-in production for the full Dawson field periodically during the
        month of September.

        During the third quarter of 2009, the Trust spent $41.7 million on
        development activities in the Dawson area including drilling four
        horizontal wells and two vertical wells that were drilled and
        completed during the quarter. ARC tested eight Dawson horizontal
        wells during the quarter at rates between seven and 11 mmcf per day
        of natural gas at a flowing pressure of 1,600 to 2,000 pounds per
        square inch.

        At this time, the Trust has 23 wells drilled in the Dawson gas field
        that are in various stages of completion. In the completed and
        waiting on tie-in category are 18 wells (11 horizontal and seven
        vertical), while the remaining five wells (all horizontal) are yet to
        be completed. In addition to these Dawson wells, ARC has drilled five
        vertical wells and two horizontal wells in the Sunrise-Sunset area,
        none of which are tied-in.

        In the Montney West lands, ARC drilled a well at Sunset to hold land
        that was due to expire in the fourth quarter of 2009 allowing ARC to
        pursue future drilling opportunities on this land. ARC is
        participating in a small development project on partner operated
        lands at Sunrise. Current plans call for the drilling of four
        horizontal wells, construction of pipelines and a gathering system
        and the expansion of a third party operated gas plant. At quarter
        end, two horizontal wells had been drilled that will be completed in
        the fourth quarter. Assuming that the drilling and construction go as
        planned, production from this area should be approximately 10 mmcf
        per day net to ARC's 50 per cent working interest by the beginning of
        2010.

        Due to regulatory delays in receiving final approvals, we now believe
        the Dawson Phase 1, 60 mmcf per day gas plant start-up will be early
        in the second quarter of 2010. Year-to-date $29.8 million has been
        spent on the gas plant. The British Columbia Oil and Gas Commission
        ("OGC") has granted conditional approvals, prior to final permit
        approval, for: site grading (which is completed), pounding pilings
        (completed pounding 1,350 pilings), mobilizing mechanical
        contractor's trailers and equipment to site (in progress) and setting
        major equipment skids (modules are being transported to site). Once
        final permit approval is received from the OGC all on-site
        construction will begin.

    -   Enhanced Oil Recovery Initiatives

        During the third quarter, the Trust spent $7.5 million on enhanced
        oil recovery ("EOR") initiatives and received $2.8 million in funding
        from the Alberta Government for the Redwater pilot project for net
        spending of $4.7 million during the quarter. Work on the Redwater
        CO(2) pilot project continues and both the CO(2) injection and oil
        production facilities are operating. Results to date are encouraging
        but the Trust anticipates that it will take until the first quarter
        of 2010 to determine to what extent the pilot has been successful in
        mobilizing incremental volumes of oil. While the pilot project may
        indicate enhanced recovery, the outlook for crude oil prices and the
        cost and availability of CO(2) will be determining factors in the
        Trust's ability to achieve commercial viability for a full scale EOR
        scheme at Redwater.

ARC's Business

ARC Energy Trust ("ARC") or ("the Trust") is an actively managed oil and natural gas entity formed to provide investors with indirect ownership in cash generating energy assets, that currently consist of oil and natural gas assets. The cash flow from operating activities is based on the production and sale of crude oil, natural gas liquids and natural gas.

ARC is one of the top 20 producers of conventional oil and natural gas in western Canada. As at September 30, 2009, ARC held interests in excess of 18,650 wells with approximately 5,700 wells operated by ARC and the remainder principally operated by other major oil and gas companies. ARC's production has averaged between 61,000 and 67,000 boe per day in each quarter for the last three years. The total capitalization of ARC, which trades on the Toronto Stock Exchange, as at September 30, 2009 was $5.5 billion as shown on Table 23.

ARC's Objective

ARC's objective is to be one of the top performing oil and gas companies in Canada as measured by quality of assets, management expertise and investor returns. The focus is on risk managed value creation. Table 1 shows the Trust's ability to maintain stable production and reserves per unit while distributing a portion of the cash flows back to unitholders. The decrease in 2009 production per unit reflects the impact of issuing 15.5 million trust units in the first quarter that raised $240 million used to partially fund capital expenditures in the Dawson area. ARC is constructing a 60 mmcf per day capacity gas plant with an expectation that production per unit will increase in 2010 upon startup of this plant.

    (1) Normalized indicates that all periods as presented have been adjusted
        to reflect a net debt to capitalization of 15 per cent. It is assumed
        that additional trust units were issued (or repurchased) at a period
        end price for the reserves per unit calculation and at an annual
        average price for the production per unit calculation in order to
        achieve a net debt balance of 15 per cent of total capitalization
        each year. The normalized amounts are presented to enable
        comparability of per unit values.
    (2) Production per unit represents daily average production (boe) per
        thousand trust units and is calculated based on daily average
        production divided by the normalized weighted average trust units
        outstanding including trust units issuable for exchangeable shares.
    (3) Reserves per unit are calculated based on proved plus probable
        reserves (boe) at period end divided by period end trust units
        outstanding including trust units issuable for exchangeable shares.
    >>

Currently the Trust distributes $0.10 per unit per month. The remainder of the cash flow is used to fund reclamation costs, and a portion of capital expenditures and land acquisitions. Since the Trust's inception in July 1996 to September 30, 2009, the Trust has distributed $3.5 billion or $24.68 per unit.

ARC's business plan has resulted in significant operational success as seen in Table 2 where the Trust's trailing five year annualized return per unit was 14.3 per cent. However, commodity prices and the current economic downturn are significant factors impacting the profitability of ARC and capital appreciation of our trust units in the market place. The impact of these external factors has led to a negative return for the trailing one year despite the successful execution of ARC's business plan and operational successes.

    (1) The Trust has revised full year 2009 operating costs from the
        original estimate of $10.70 per boe to be approximately $10.50 per
        boe or $243 million based on annual production of between 63,000 and
        64,000 boe per day. This decrease is to reflect lower electricity
        costs recorded throughout the third quarter and overall costs savings
        being achieved by the operations team.
    (2) Full year transportation expense has been revised downward to $0.90
        per boe from $1.00 per boe based on reduced estimates for oil
        trucking requirements throughout the third and fourth quarters.
    (3) G&A guidance amount of $2.10 per boe includes $1.75 per boe for cash
        G&A costs, $0.55 per boe for cash Whole Unit Plan costs and a
        recovery of $0.20 per boe for non-cash portion of the Whole Unit
        Plan.
    (4) Full year capital expenditures are now expected to be approximately
        $365 million, an increase of $15 million over second quarter guidance
        as the Trust has chosen to increase capital spending in Alberta and
        British Columbia to take advantage of royalty incentives announced by
        those provinces.

        equivalent at the well head. Use of boe in isolation may be
        misleading.

Net Income

Net income in the third quarter of 2009 was $68.9 million ($0.29 per unit), a decrease of $242.8 million from $311.7 million ($1.46 per unit) in the third quarter of 2008. The net income recorded in the third quarter of 2008 reflected certain non-cash gains, as detailed below, resulting in record net income when combined with the strong commodity prices received for the quarter. Net income for the third quarter of 2009 reflects the decreased commodity price environment in the current year and includes certain non-cash items that also served to increase the net income during the period.

In the third quarter of 2008, the Trust recorded a $187.5 million unrealized non-cash gain on risk management contracts ($140.6 million net of future income taxes). As well, the Trust recorded a $15.5 million non-cash foreign exchange loss on its U.S. denominated debt as a result of the movement in the Canadian dollar relative to the U.S. dollar ($13.6 million net of future income taxes).

In the third quarter of 2009, the Trust recorded a $34.9 million non-cash foreign exchange gain on U.S. denominated debt ($30.5 million net of future income taxes) and a $0.7 million unrealized non-cash loss on risk management contracts ($0.5 million net of future income taxes).

A measure of sustainability is the comparison of net income to distributions. Net income incorporates all costs including depletion expense and other non-cash expenses whereas cash flow from operating activities measures the cash generated in a given period before the cost of acquiring or replacing the associated reserves produced. Therefore, net income may be more representative of the profitability of the entity and thus a relevant measure against which to measure distributions to illustrate sustainability. As net income is sensitive to fluctuations in commodity prices and the impact of risk management contracts, currency fluctuations and other non-cash items, it is expected that there will be deviations between annual net income and distributions. Table 5 illustrates the comparison of distributions to net income as a measure of long-term sustainability. Distributions have been reduced from $0.24 per unit per month in October 2008 to the current rate of $0.10 per unit per month.

Cash Flow from Operating Activities

Cash flow from operating activities decreased by 50 per cent in the third quarter of 2009 to $125.6 million from $251.4 million in the third quarter of 2008. Decreases in crown royalties and cash losses on risk management contracts were more than offset by the 49 per cent ($40.11 per boe) decrease in commodity prices relative to the third quarter of 2008 as well as a two per cent decrease in volumes during the period. The decrease in third quarter 2009 cash flow from operating activities compared with the third quarter of 2008 is detailed in Table 6.

Production

Production volumes averaged 62,824 boe per day in the third quarter of 2009 compared to 64,325 boe per day in the same period of 2008 as detailed in Table 8. The decrease in third quarter 2009 production is a result of turnarounds at the Dawson property as well as natural production declines as a result of the decreased capital spending in 2009.

Light and medium crude oil production decreased to 25,930 boe per day compared to 27,211 boe per day in 2008, while heavy oil production declined by 307 boe per day. When compared to the second quarter of 2009, the total crude oil production is relatively flat, as a result of a successful drilling program at Goodlands, Pembina and Ante Creek that helped to offset natural decline. Natural gas production was 193.1 mmcf per day in the third quarter of 2009, an increase of one per cent from the 192 mmcf per day produced in the third quarter of 2008 but down 3.5 per cent from the second quarter of 2009. The decrease in production over the second quarter of 2009 is due primarily to the planned turnaround completed at a third party facility that shut-in production at Dawson periodically throughout the month of September as well as other turnarounds in the Northern Alberta district that occurred during the month of July.

The Trust's objective is to maintain annual production through the drilling of wells and other development activities to the full extent possible while giving considerations to capital spending constraints. In fulfilling this objective, there may be fluctuations in production depending on the timing of new wells coming on-stream. During the third quarter of 2009, the Trust drilled 17 gross wells (16 net wells) on operated properties; 11 gross oil wells, and six gross natural gas wells with a 100 per cent success rate. Of the wells drilled during the third quarter, two gas wells and seven oil wells were completed. Five of the oil wells completed were brought on production during the quarter.

The Trust expects that 2009 full year production will average approximately 63,000 to 64,000 boe per day and that a total of 146 gross wells (120 net) will be drilled by ARC on operated properties with participation in an additional 54 gross wells to be drilled on the Trust's non-operated properties. The Trust estimates that the revised 2009 drilling program will add sufficient production from new wells to offset the majority of production declines on existing properties, however, overall production is expected to decrease by 1,000 to 2,000 boe per day relative to 2008 production levels. The planned capital expenditures for 2009 have been increased to approximately $365 million to take advantage of royalty incentives announced by the provinces of Alberta and British Columbia.

Revenue

Revenue decreased to $239.2 million in the third quarter of 2009, $246.5 million lower than 2008 revenues of $485.7 million. The decrease in realized oil prices accounted for a $121.9 million decrease in revenues with only $9.9 million of the decrease attributable to lower oil volumes. Natural gas revenue decreased by $95.6 million which was almost entirely attributable to decreased realized prices as volumes were flat over the same period in 2008.

A breakdown of revenue is outlined in Table 10:

Oil prices continued to recover in the third quarter of 2009 with US$WTI prices averaging $68.29 as compared to $51.46 for the first half of 2009. Despite this recovery, prices in the third quarter of 2009 were down 42 per cent compared to the same period of 2008 as detailed in Table 11. This large decrease was partially offset by the weakening of the Canadian dollar compared to the U.S. dollar; however, some widening of the price differentials further eroded the Trust's realized oil price. The Trust's oil production consists predominantly of light and medium crude oil while heavy oil accounts for less than five per cent of the Trust's crude oil production. The realized price for the Trust's oil, before hedging, was $67.74 per boe, a 41 per cent reduction over the third quarter 2008 realized price of $114.20 per boe.

Natural gas prices softened throughout the third quarter of 2009. Alberta AECO Hub natural gas prices, which are commonly used as an industry reference, averaged $3.03 per mcf in the third quarter of 2009 compared to $9.27 per mcf in the same period of 2008. ARC's realized gas price, before hedging, decreased by 63 per cent to $3.25 per mcf compared to $8.68 per mcf in the third quarter of 2008. ARC's realized gas price is based on prices received at the various markets in which the Trust sells its natural gas. ARC's natural gas sales portfolio consists of gas sales priced at the AECO monthly index, the AECO daily spot market, eastern and mid-west United States markets and a portion to aggregators. Natural gas prices have started to recover in the fourth quarter of 2009 with posted prices in the month of October registering over $5 per mcf. In addition, the forward curve for natural gas prices has strengthened to reflect 2010 prices of over $6 per mcf. Management is pursuing strategic initiatives to capitalize on strong forward prices, where possible in order to protect the economics of the 2010 capital program.

Prior to hedging activities, ARC's total realized commodity price was $41.31 per boe in the third quarter of 2009, a 49 per cent decrease from the $81.42 per boe received prior to hedging in the third quarter of 2008.

Risk Management and Hedging Activities

ARC maintains an ongoing risk management program to reduce the volatility of revenues in order to increase the certainty of distributions, protect acquisition economics, and fund capital expenditures.

Gain or loss on risk management contracts comprise realized and unrealized gains or losses on risk management contracts that do not meet the accounting definition requirements of an effective hedge, even though the Trust considers all risk management contracts to be effective economic hedges. Accordingly, gains and losses on such contracts are shown as a separate category in the statement of income.

Lower natural gas prices in the third quarter of 2009 resulted in realized cash gains of $10.4 million on natural gas risk management contracts as the Trust's contracted prices were higher than market prices during the quarter. Realized cash losses of $3.6 million were recorded on the Trust's crude oil risk management contracts as a result of premiums paid during the third quarter of 2009 and small losses recorded on the Trust's fixed price swap contracts where the market oil price rose above the contracted price.

ARC's third quarter 2009 results include an unrealized total mark-to- market loss of $0.7 million with a net unrealized mark-to-market loss position of $4.8 million as at September 30, 2009. The net loss position is mostly attributed to losses on the Trust's power and natural gas contracts and offset by gains on the Trust's crude oil contracts. The mark-to-market values represent the market price to buy-out the Trust's contracts as of September 30, 2009 and may differ from what will eventually be realized.

In the third quarter of 2008, the Trust recorded a significant unrealized gain on risk management contracts as commodity prices, and in particular oil prices, declined significantly at the end of the quarter when compared to the previous reporting period. The realized cash losses in the third quarter of 2008 were mostly attributable to crude oil contracts where the market prices were in excess of ARC's contracted price.

Table 12 summarizes the total gain (loss) on risk management contracts for the third quarter of 2009 as compared to the same period in 2008:

    (1) The prices and volumes noted above represent averages for several
        contracts and the average price for the portfolio of options listed
        above does not have the same payoff profile as the individual option
        contracts. Viewing the average price of a group of options is purely
        for indicative purposes. The natural gas price shown translates all
        NYMEX positions to an AECO equivalent price.
    (2) In addition to positions shown here, ARC has entered into additional
        basis positions until October 2012, an energy equivalent swap until
        December 31, 2009. Please refer to note 8 in the Notes to the
        Consolidated Financial Statements for full details of the Trust's
        risk management positions as of September 30, 2009.
    (3) The natural gas contract listed for 2010 is a fixed price swap
        starting in 2010 and ending in December 2013. During the quarter, the
        Trust took advantage of favorable forward curve pricing for natural
        gas and entered into a long-term contract for a small portion of
        future forecast production.

Table 13 should be interpreted as follows using the fourth quarter 2009 crude oil hedges as an example. To accurately analyze the Trust's hedge position, contracts need to be modeled separately as using average prices and volumes may be misleading.

    -   If the market price is below $42.89, ARC will receive $67.61 less the
        difference between $42.89 and the market price on 2,500 bbl per day.
        For example if the market price is $42.85, the Trust will receive
        $67.57 on 2,500 bbl per day.
    -   If the market price is between $42.89 and $67.61, ARC will receive
        $67.61 on 9,500 bbl per day.
    -   If the market price is between $67.61 and $83.02, ARC will receive

Operating Netbacks

The Trust's operating netback, before realized hedging gains and losses, decreased 57 per cent to $24.35 per boe in the third quarter of 2009 compared to $56.07 per boe in the same period of 2008. The decrease in netbacks is due most significantly to the reduced commodity prices and the corresponding reduction in royalties in the period.

The Trust's third quarter 2009 netback, after realized hedging gains and losses, was $25.47 per boe, a 49 per cent decrease from the same period in 2008. The 2009 netback includes net gains recorded on the Trust's crude oil and natural gas risk management contracts during the quarter of $1.12 per boe compared to a net loss of $5.79 per boe recorded for the same period in 2008.

The components of operating netbacks are summarized in Table 14 and 14a:

Royalties as a percentage of pre-hedged commodity revenue net of transportation decreased to 16.1 per cent ($6.53 per boe) in the third quarter of 2009 compared to 18.5 per cent ($15.00 per boe) in 2008. Royalties for the first nine months of 2009 decreased to 14.9 per cent ($5.86 per boe) as compared to 18.2 per cent ($14.18) for the same period of 2008.

The Alberta Government's Alberta Royalty Framework ("Framework" or "ARF") took effect January 1, 2009 and provides for sliding scale crown royalty rates whereby rates increase in high commodity price environments and decrease in low commodity price environments. The 2009 royalty rate is in line with Management's expectations due to the low natural gas price environment. The recovery of crude oil prices in the third quarter of 2009 has resulted in higher oil crown royalty payments as compared to the first half of 2009.

Following the implementation of the ARF, the Alberta Government introduced certain transitional rates and incentive programs to provide royalty relief to producers and in turn encourage continued drilling activity in the province. ARC will be eligible for the Alberta programs assuming the necessary criteria are met and required elections are filed. The drilling credit program applies to new wells drilled between April 1, 2009 and March 31, 2011 and is currently estimated to generate a maximum $15 million credit over the two year period based on forward looking prices at this time. The Trust is automatically eligible for the reduced royalty rate incentive on new production for wells coming on production between April 1, 2009 and March 31, 2011. These wells will receive a crown royalty rate of five per cent subject to certain production limits.

During the third quarter of 2009 the British Columbia government announced a new Stimulus Package designed to attract investment and produce immediate economic benefits for the province. The stimulus package included royalty incentives in the form of reduced royalty rates for wells drilled in the province between September 1, 2009 and June 30, 2010 and modifications to the existing deep well drilling program to increase available credits and expand depth criteria whereby additional wells may qualify for the program. ARC estimates that the deep well drilling credits could save approximately $1 million per horizontal well drilled. These credits will be recorded as a reduction to royalty expense to the extent that royalties are incurred on the well drilled. The royalty reduction program will result in a two per cent maximum royalty rate for a period of 12 months. Management estimates that for wells that do not qualify for the drilling credit program this incentive could generate savings of $1 million per well at natural gas prices of $3 per mcf to $2.5 million per well at natural gas prices of $7 per mcf. Wells that qualify for the drilling credit program must draw down the drilling credit before qualifying for the reduced royalty program. Management plans to drill 20 wells in British Columbia on operated properties during the incentive period in order to maximize the total benefit to ARC and its unitholders. New wells drilled that will qualify for the two per cent royalty incentive are expected to come on production in the third and fourth quarters of 2010.

Operating costs decreased to $9.68 per boe compared to $10.19 per boe in the third quarter of 2008. Total operating costs decreased $4.3 million, or seven per cent in the third quarter of 2009 as compared to the third quarter of 2008. The decrease in costs is primarily attributed to lower power costs in 2009 as well as some cost savings and efficiencies achieved by the operations team.

The Trust has revised full year 2009 operating costs from the original estimate of $10.70 per boe to be approximately $10.50 per boe or $243 million based on annual production of between 63,000 and 64,000 boe per day. This decrease is to reflect lower electricity costs recorded throughout the third quarter and overall costs savings being achieved by the operations team.

General and Administrative ("G&A") Expenses and Trust Unit Incentive

Compensation

G&A, prior to long-term incentive payments under the Whole Unit Plan and net of overhead recoveries on operated properties, increased 13 per cent to $10.2 million in the third quarter of 2009 from $9 million in 2008. The modest increase in G&A expenses was due to a decrease in operating recoveries of $1 million resulting from lower levels of capital spending during the quarter.

A cash payment was made under the Whole Unit Plan in September 2009 for $8.6 million, of which $6.1 million was recorded in G&A with the remainder of $2.5 million being recorded to operating costs and capital projects. There was no cash payment made in the third quarter of 2008, as the corresponding cash payment of $9.7 million was made in the fourth quarter of 2008 of which $6.9 million was recorded in G&A. The next cash payment under the Whole Unit Plan is scheduled to occur in March 2010.

A non-cash Whole Unit Plan recovery ("non-cash compensation recovery") of $0.4 million ($0.07 per boe) was recorded in the third quarter of 2009 compared to a recovery of $5.5 million ($0.93 per boe) in 2008. The recovery in 2009 relates to the estimated costs of the plan to September 30, 2009, offset by a reversal of the accrual for the cash payment made in the third quarter. The 2008 non-cash amount relates to a decrease in the liability of the units outstanding due to the decrease in the trust unit price relative to the closing price of the trust units at June 30, 2008.

Whole Unit Plan

The Whole Unit Plan is designed to offer each employee, officer and director (the "plan participants") cash compensation in relation to the value of a specified number of underlying trust units. The Whole Unit Plan consists of Restricted Trust Units ("RTUs") for which the number of units is fixed and will vest over a period of three years and Performance Trust Units ("PTUs") for which the number of units is variable and will vest at the end of three years.

Upon vesting, the plan participant is entitled to receive a cash payment based on the fair value of the underlying trust units plus accrued distributions. The cash compensation issued upon vesting of the PTUs is dependent upon the performance of the Trust compared to its peers and indicated by the performance multiplier. The performance multiplier is based on the percentile rank of the Trust's total unitholder return compared to its peers. Total return is calculated as the sum of the change in the market price of the trust units in the period plus the amount of distributions in the period. The performance multiplier ranges from zero, if ARC's performance ranks in the bottom quartile, to two for top quartile performance.

Table 16 shows the changes to the Whole Unit Plan during the first nine months of 2009 along with the estimated value upon vesting of the plan as at September 30, 2009:

        estimated distributions accruing to vesting date.
    (3) The performance multiplier only applies to PTUs and was estimated to
        be 1.3 at September 30, 2009 based on an average calculation of all
        outstanding grants. The performance multiplier is assessed each
        period end based on actual results of the Trust relative to its peers
        except during the first year of each grant where a performance
        multiplier of 1.0 is used.
    >>

The value associated with the RTUs and PTUs is expensed in the statement of income over the vesting period with the expense amount being determined by the trust unit price, the number of PTUs to be issued on vesting, and distributions. In periods where substantial trust unit price fluctuation occurs, the Trust's G&A expense is subject to significant volatility.

    (1) Includes additional estimated units to be issued for accrued
        distributions to vesting date.
    (2) Values will fluctuate over the vesting period based on the volatility
        of the underlying trust unit price and distribution levels. Assumes a
        future trust unit price of $20.20 and $0.10 per trust unit
        distributions based on the unit price and distribution levels in
        place at September 30, 2009.
    (3) Upon vesting, a cash payment is made equivalent to the value of the
        underlying trust units. The payment is made on vesting dates in March
        and September of each year and at that time is reflected as a
        reduction of cash flow from operating activities.
    >>

Due to the variability in the future payments under the plan, the Trust estimates that between $25 million and $90.6 million will be paid out from 2010 through 2012 based on the current trust unit price, distribution levels and the Trust's market performance relative to its peers.

Interest and financing charges

Interest and financing charges decreased to $6.4 million in the third quarter of 2009 from $7.8 million in 2008 due to a decrease in short-term interest rates as well as a lower amount of debt outstanding. As at September 30, 2009, the Trust had $637.1 million of long-term debt outstanding, of which $355 million was fixed at a weighted average rate of six per cent and $282.1 million, including the working capital facility, was floating at current market rates plus a credit spread of 60 basis points. Sixty per cent (US$355.1 million) of the Trust's debt outstanding is denominated in U.S. dollars. The Trust's credit facility is a three year facility maturing in April 2011. Management's current expectation is that the current 60 point credit spread would increase upon renewal by 150 to 250 basis points.

Foreign Exchange Gains and Losses

The Trust recorded a gain of $34.9 million in the third quarter of 2009 on foreign exchange transactions compared to a loss of $16.3 million in 2008. These amounts include both realized and unrealized foreign exchange gains and losses.

Realized foreign exchange gains or losses arise from U.S. denominated transactions such as interest payments, debt repayments and hedging settlements. There were no cash realized foreign exchange gains during the quarter, however a non-cash realized gain of $2.5 million was recorded during the quarter relating to a debt repayment of $30 million made during the quarter. This debt repayment was financed with the Trust's credit facility and therefore is considered to be a non-cash transaction.

Unrealized foreign exchange gains and losses are due to revaluation of U.S. denominated debt balances. The volatility of the Canadian dollar during the reporting period has a direct impact on the unrealized component of the foreign exchange gain or loss. The unrealized gain or loss impacts net income but does not impact cash flow from operating activities as it is a non-cash amount. From June 30, 2009 to September 30, 2009, the Cdn$/US$ exchange rate decreased from 1.16 to 1.07 resulting in an unrealized gain of $32.4 million on U.S. dollar denominated debt.

Taxes

In the third quarter of 2009, a future income tax recovery of $5.7 million was included in income compared to an expense of $48.4 million in the third quarter of 2008. The large expense in 2008 was attributable to the unrealized risk management contract gains recorded during the same period.

The corporate income tax rate applicable to 2009 is 29 per cent; however the Trust and its subsidiaries did not pay any material cash income taxes for the third quarter of 2009. Due to the Trust's structure, currently, both income tax and future tax liabilities are passed on to the unitholders by means of royalty payments made between ARC Resources and the Trust.

Management continues to work on the plan for converting ARC Energy Trust to a corporation on January 1, 2011. After the conversion, the corporation would expect to allocate its cash flow among funding a portion of capital expenditures, periodic debt repayments, site reclamation expenditures, and cash payments to shareholders in the form of dividends. Current taxes payable by ARC after converting to a corporation will be subject to normal corporate tax rates. Taxable income as a corporation will vary depending on total income and expenses and vary with changes to commodity prices, costs, claims for both accumulated tax pools and tax pools associated with current year expenditures. As ARC has accumulated $2.2 billion of income tax pools, taxable income will be reduced or potentially eliminated for the initial period post conversion. The $2.2 billion of income tax pools (detailed in Table 18) are deductible at various rates and annual deductions associated with the initial tax pools will decline over time.

Returns to shareholders post conversion will be impacted by the reduction of cash flow required to pay current income taxes, if any. Over the longer term, we would expect Canadian investors who hold their trust units in a taxable account will be relatively indifferent on an after tax basis as to whether ARC is structured as a corporation or as a trust in 2011. However, Canadian tax deferred investors (those holding their trust units in a tax deferred vehicle such as an RRSP, RRIF or pension plan) and foreign investors will realize a lower after tax return on distributions in taxable years after 2011 due to the introduction of the SIFT Tax should ARC stay as a trust, and their inability to claim the dividend tax credit if ARC converts to a corporation.

If a conversion from the trust structure to a corporation is approved by the unitholders, the income tax payable by unitholders will vary and each unitholder should consult their own tax advisor for details on the direct impact to themselves.

Depletion, Depreciation and Accretion of Asset Retirement Obligation

The depletion, depreciation and accretion ("DD&A") rate increased to $16.55 per boe in the third quarter of 2009 from $15.79 per boe in the third quarter of 2008. The Trust posted a large increase in proved reserves at year- end 2008; however, these reserves were offset by a significant increase in the future development costs required to convert proven undeveloped reserves to proven producing reserves.

A breakdown of the DD&A rate is summarized in Table 19:

Capital Expenditures and Net Acquisitions

Capital expenditures, excluding acquisitions and dispositions, totaled $96.2 million in the third quarter of 2009 compared to $136.4 million in the same period of 2008. This amount was incurred on drilling and completions, geological, geophysical and facilities expenditures.

Of the total amount spent in the third quarter, $52.7 million was spent on the Montney resource play while the remaining $43.5 million was spent on the remainder of the Trust's conventional portfolio, which has produced strong production results despite the reduced capital re-investment in 2009.

In addition to capital expenditures on development activities during the third quarter, the Trust completed small property acquisitions of $6.8 million and a small acquisition of undeveloped land for $0.4 million. The Trust completed property dispositions of $37.3 million that included a previously disclosed disposition of non-core assets in southeast Saskatchewan for proceeds of $33.5 million. This disposition will have no material impact on the forecast production volumes for the year.

For the remainder of 2009, the Trust expects to drill 39 gross wells (38 net wells) on operated properties, complete all wells in inventory and proceed with construction of the Dawson gas plant that is expected to be operational by early second quarter of 2010. Total capital expenditures are forecast to be $365 million in 2009.

Approximately 72 per cent of the $96.2 million capital program in the third quarter of 2009 was financed with cash flow from operating activities and proceeds from the distribution re-investment plan ("DRIP") compared to 86 per cent for the same period of 2008. Including proceeds from the net dispositions completed during the quarter, the Trust funded 100 per cent of third quarter capital expenditures from internal sources. On a year-to-date basis, the Trust has funded 72 per cent of the capital expenditures with cash flow from operating activities and proceeds from the DRIP as compared to 100 per cent for the first nine months of 2008. Including proceeds from the net dispositions, year-to-date capital expenditures were 79 per cent funded internally with the remaining 21 per cent funded through debt and working capital.

Asset Retirement Obligation and Reclamation Fund

At September 30, 2009, the Trust recorded an Asset Retirement Obligation ("ARO") of $145.6 million ($141.5 million at December 31, 2008) for future abandonment and reclamation of the Trust's properties.

Included in the September 30, 2009 ARO balance was a $1 million increase related to development activities and changes in estimates in the first nine months of 2009, $7 million for accretion expense in the period and a reduction of $3.9 million for actual abandonment expenditures incurred in the first nine months of 2009.

ARC's reclamation funds held $31.8 million as at September 30, 2009. Under the terms of the Trust's investment policy, reclamation fund investments and excess cash can only be invested in Canadian or U.S. Government securities, investment grade corporate bonds, or investment grade short-term money market securities.

    (1) Net debt is a non-GAAP measure and therefore it may not be comparable
        with the calculation of similar measures for other entities. It is
        calculated as long-term debt plus current liabilities less the
        current assets as they appear on the Consolidated Balance Sheets. Net
        debt excludes current unrealized amounts pertaining to risk
        management contracts and the current portion of future income taxes.
    (2) Calculated using the total trust units outstanding at September 30
        and December 31 including the total number of trust units issuable
        for exchangeable shares at September 30 and December 31 multiplied by
        the closing trust unit price of $20.20 and $20.10 at September 30,

        meaning prescribed by Canadian GAAP and therefore it may not be
        comparable with the calculation of similar measures for other
        entities. Total capitalization is not intended to represent the total
        funds from equity and debt received by the Trust.

At September 30, 2009, the Trust's current credit facilities comprised Cdn$355 million in senior secured notes currently outstanding, a Cdn$800 million syndicated bank credit facility, of which Cdn$268.1 million was outstanding and a Cdn$25 million demand working capital facility, of which $14 million was outstanding. The credit facility syndicate includes 11 domestic and international banks. The Trust's debt agreements contain a number of covenants all of which were met as at September 30, 2009; these agreements are available at www.SEDAR.com.

As at September 30, 2009, the Trust has approximately $680 million of unused credit available: $532 million under its credit facility, and $148 million available to draw long-term notes under a master shelf agreement with an insurance company.

As a result of the weakened global economic situation, the Trust along with all other oil and gas entities may have restricted access to capital and increased borrowing costs. Although the Trust's business and asset base have not changed, the lending capacity of all financial institutions has been diminished and risk premiums have increased. These issues will impact the Trust as it reviews financing alternatives for the 2010 capital program, assesses potential future acquisition opportunities and manages future cash flow decremented by lower commodity prices and higher borrowing costs. The Trust intends to finance its 2010 capital program with cash flow, existing credit facilities, proceeds from the DRIP, potential asset dispositions and new borrowings or equity if necessary. Beyond that, the Trust may need to access additional capital and/or curtail capital expenditure plans and will look to do so in the most cost effective manner possible.

Unitholders' Equity

At September 30, 2009, there were 235.7 million trust units issued and issuable for exchangeable shares, an increase of 19.3 million trust units from December 31, 2008 due mostly to the issuance of 15.5 million trust units as part of an equity offering in February 2009.

Unitholders electing to reinvest distributions or make optional cash payments to acquire trust units from treasury under the DRIP may do so at a five per cent discount to the prevailing market price with no additional fees or commissions. During the first nine months of 2009, the Trust raised proceeds of $51.7 million and issued 3.3 million trust units pursuant to the DRIP at an average price of $15.73 per unit.

Distributions

ARC declared distributions of $70.6 million ($0.30 per unit), representing 56 per cent of 2009 third quarter cash flow from operating activities compared to distributions of $171.3 million ($0.80 per unit) representing 68 per cent of cash flow from operating activities in the third quarter of 2008.

The following items may be deducted from cash flow from operating activities to arrive at distributions to unitholders:

    <<
    -   The portion of capital expenditures that are funded with cash flow
        from operating activities. In the first nine months of 2009, the
        Trust withheld approximately 35 per cent of cash flow from operating
        activities to fund 51 per cent of the capital program excluding
        acquisitions. The remaining portion of capital expenditures was
        financed by proceeds from the DRIP program, proceeds from net
        dispositions and debt.

    -   An annual contribution to the reclamation funds, with $11.3 million
        scheduled to be contributed in 2009. The reclamation funds are
        segregated bank accounts or subsidiary trusts and the balances will
        be drawn on in future periods as the Trust incurs abandonment and
        reclamation costs over the life of its properties.

    -   Debt principal repayments on the Trust's credit facility from time to
        time as determined by the board of directors. The Trust's current
        debt level is well within the covenants specified in the debt
        agreements and, accordingly, there are no current mandatory
        requirements for repayment.

    -   Income taxes that are not passed on to unitholders. The Trust has a
        liability for future income taxes due to the excess of book value
        over the tax basis of the assets of the Trust and its corporate
        subsidiaries. The Trust currently, and up until January 1, 2011, may
        minimize or eliminate cash income taxes in corporate subsidiaries by
        maximizing deductions, however in future periods there may be cash
        income taxes if deductions are not sufficient to eliminate taxable
        income. Taxability of the Trust is currently passed on to unitholders
        in the form of taxable distributions whereby corporate income taxes
        are eliminated at the Trust level. The Trust taxation legislation,
        which will take effect in 2011, will result in taxes payable at the
        Trust level and therefore distributions to unitholders would decrease
        if ARC remained as a trust.

    -   Working capital requirements as determined by the board of directors.
        Certain working capital amounts may be deducted from cash flow from
        operating activities, however such amounts would be minimal and the
        Trust does not anticipate any such deductions in the foreseeable
        future.

    -   The Trust has certain obligations for future payments relative to
        employee long-term incentive compensation under the Whole Unit Plan.
        Presently, the Trust estimates that $25 million to $90.6 million will
        be paid out pursuant to such commitments in 2010 through 2012 subject
        to vesting provisions and future performance of the Trust. These
        amounts will reduce cash flow from operating activities and may in
        turn reduce distributions in future periods.

    >>

The Trust continually assesses distribution levels, in light of commodity prices, capital expenditure programs and production volumes, to ensure that distributions are in line with the long-term strategy and objectives of the Trust as per the following guidelines:

    <<
    -   To maintain a level of distributions that, in normal times, in the
        opinion of Management and the Board of Directors, is sustainable for
        a minimum period of six months after factoring in the impact of
        current commodity prices on cash flows. The Trust's objective is to
        normalize the effect of volatility of commodity prices rather than to
        pass on that volatility to unitholders in the form of fluctuating
        monthly distributions.

    -   To ensure that the Trust's financial flexibility is maintained by a
        review of the Trust's debt to equity and debt to cash flow from
        operating activities levels. The use of cash flow from operating
        activities and proceeds from equity offerings to fund capital
        development activities reduces the requirements of the Trust to use
        debt to finance these expenditures. In the first nine months of 2009,
        the Trust funded 51 per cent of capital development activities with a
        portion of cash flow from operating activities. Distributions and the
        actual amount of cash flows withheld to fund the Trust's capital
        expenditure program is dependent on the commodity price environment
        and is subject to the approval and discretion of the Board of
        Directors.
    >>

The actual amount of future monthly distributions is proposed by Management and is subject to the approval and discretion of the Board of Directors. The Board reviews future distributions in conjunction with their review of quarterly financial and operating results.

Please refer to the Trust's website at www.arcenergytrust.com for details of the monthly distribution amounts and distribution dates for 2009.

Environmental Initiatives Impacting the Trust

There are no new environmental initiatives impacting the Trust at this time.

Contractual Obligations and Commitments

The Trust has contractual obligations in the normal course of operations including purchase of assets and services, operating agreements, transportation commitments, sales commitments, royalty obligations, and lease rental obligations and employee agreements. These obligations are of a recurring and consistent nature and impact the Trust's cash flows in an ongoing manner. The Trust also has contractual obligations and commitments that are of a less routine nature as disclosed in Table 24.

    (1) Long-term and short-term debt, excluding interest.
    (2) Fixed interest payments on senior secured notes.
    (3) Contribution commitments to a restricted reclamation fund associated
        with the Redwater property.
    (4) Fixed payments for transporting production from the Dawson gas plant,
        expected to be operational in early second quarter of 2010.
    (5) Fixed premiums to be paid in future periods on certain commodity risk
        management contracts.
    >>

The above noted risk management contract premiums are part of the Trust's commitments related to its risk management program and have been recorded at fair market value at September 30, 2009 on the balance sheet as part of risk management contracts. In addition to the premiums, the Trust has commitments related to its risk management program.

The Trust enters into commitments for capital expenditures in advance of the expenditures being made. At any given point in time, it is estimated that the Trust has committed to capital expenditures equal to approximately one quarter of its capital budget by means of giving the necessary authorizations to incur the capital in a future period. The Trust's 2009 capital budget has been approved by the Board at $365 million. This commitment has not been disclosed in the commitment table (Table 24) as it is of a routine nature and is part of normal course of operations for active oil and gas companies and trusts.

The 2009 capital budget of $365 million includes $11 million for leasehold development costs related to the Trust's new office space in downtown Calgary. These costs will be incurred throughout 2009 with additional costs to be incurred in 2010. The operating lease commitments for the new space begin in the first quarter of 2010 and are included in Table 24.

The Trust is involved in litigation and claims arising in the normal course of operations. Management is of the opinion that pending litigation will not have a material adverse impact on the Trust's financial position or results of operations and therefore the commitment table (Table 24) does not include any commitments for outstanding litigation and claims.

The Trust has certain sales contracts with aggregators whereby the price received by the Trust is dependent upon the contracts entered into by the aggregator. This commitment has not been disclosed in the commitment table (Table 24) as it is of a routine nature and is part of normal course of operations.

Off Balance Sheet Arrangements

The Trust has certain lease agreements, all of which are reflected in the Contractual Obligations and Commitments table (Table 24), which were entered into in the normal course of operations. All leases have been treated as operating leases whereby the lease payments are included in operating expenses or G&A expenses depending on the nature of the lease. No asset or liability value has been assigned to these leases in the balance sheet as of September 30, 2009.

Critical Accounting Estimates

The Trust has continuously evolved and documented its management and internal reporting systems to provide assurance that accurate, timely internal and external information is gathered and disseminated.

The Trust's financial and operating results incorporate certain estimates including:

    <<
    -   estimated revenues, royalties and operating costs on production as at
        a specific reporting date but for which actual revenues and costs
        have not yet been received;
    -   estimated capital expenditures on projects that are in progress;
    -   estimated depletion, depreciation and accretion that are based on
        estimates of oil and gas reserves that the Trust expects to recover
        in the future;
    -   estimated fair values of derivative contracts that are subject to
        fluctuation depending upon the underlying commodity prices and
        foreign exchange rates;
    -   estimated value of asset retirement obligations that are dependent
        upon estimates of future costs and timing of expenditures; and
    -   estimated future recoverable value of property, plant and equipment
        and goodwill.
    >>

The Trust has hired individuals and consultants who have the skills required to make such estimates and ensures that individuals or departments with the most knowledge of the activity are responsible for the estimates. Further, past estimates are reviewed and compared to actual results, and actual results are compared to budgets in order to make more informed decisions on future estimates.

The ARC leadership team's mandate includes ongoing development of procedures, standards and systems to allow ARC staff to make the best decisions possible and ensuring those decisions are in compliance with the Trust's environmental, health and safety policies.

Internal Control over Financial Reporting

ARC is required to comply with National Instrument 52-109 "Certification of Disclosure in Issuers' Annual and Interim Filings", otherwise referred to as Canadian SOX ("C-Sox"). The certification of interim filings for the interim period ended September 30, 2009 requires that the Trust disclose in the interim MD&A any changes in the Trust's internal control over financial reporting that occurred during the period that has materially affected, or is reasonably likely to materially affect the Trust's internal control over financial reporting. The Trust confirms that no such changes were made to the internal controls over financial reporting during the first nine months of 2009.

Financial Reporting Update

Future Accounting Changes

International Financial Reporting Standards ("IFRS")

In April 2008, the CICA published the exposure draft "Adopting IFRS in Canada". The exposure draft proposes to incorporate IFRS into the CICA Accounting Handbook effective for interim and annual financial statements relating to fiscal years beginning on or after January 1, 2011. At this date, publicly accountable enterprises will be required to prepare financial statements in accordance with IFRS.

The Trust has commenced the process to transition from current Canadian GAAP to IFRS. Internal staff has been appointed to lead the conversion project along with sponsorship from the leadership team. Regular progress reporting to the audit committee of the Board of Directors on the status of the IFRS conversion has been implemented.

    <<
    ARC's project consists of three key phases:

    -   Scoping and diagnostic phase - this phase involves performing a high
        level impact analysis to identify areas that may be affected by the
        transition to IFRS. The results of this analysis are priority ranked
        according to complexity and the amount of time required to assess the
        impact changes in transitioning to IFRS.

    -   Impact analysis and evaluation phase - during this phase, items
        identified in the diagnostic are addressed according to the priority
        levels assigned to them. This phase involves analysis of policy
        choices allowed under IFRS and their impact on the financial
        statements. In addition, certain potential differences are further
        investigated to assess whether there may be a broader impact to the
        Trust's debt agreements, compensation arrangements or management
        reporting systems. The conclusion of the impact analysis and
        evaluation phase will require the audit committee of the Board of
        Directors to review and approve all accounting policy choices as
        proposed by Management.

    -   Implementation phase - involves implementation of all changes
        approved in the impact analysis phase and will include changes to
        information systems, business processes, modification of agreements
        and training of all staff who are impacted by the conversion.
    >>

The Trust has completed the scoping and diagnostic phase and expects to complete the impact analysis and evaluation phase during the fourth quarter of 2009.

In July 2009, the international accounting standards board issued amendments to IFRS 1, "First-Time Adoption of International Financial Reporting Standards" ("IFRS 1"). IFRS 1 provides entities adopting IFRS for the first time with a number of optional exemptions and mandatory exceptions in certain areas to the general requirement for full retrospective application of IFRS. The amendment issued in July provides the option to value the property, plant and equipment ("PP&E") assets at their deemed cost being the net book value assigned to these assets as at the date of transition, January 1, 2010. This amendment is permissible for entities, such as the Trust, who currently follow the full cost accounting guideline under Canadian GAAP that accumulates all oil and gas assets into one cost centre. Under IFRS, the Trust's PP&E assets must be divided into smaller cost centers. The net book value of the assets on the date of transition will be allocated to the new cost centers on the basis of the Trust's reserve values at that point in time. As this is one of the Trust's largest differences from Canadian GAAP to IFRS, the Trust can now assess that this area will not create material changes to the Trust's financial results upon transition.

Non-GAAP Measures

Management uses certain key performance indicators ("KPIs") and industry benchmarks such as distributions as a per cent of cash flow from operating activities, operating netbacks ("netbacks"), total capitalization, finding, development and acquisition costs, recycle ratio, reserve life index, reserves per unit and production per unit, net asset value and total returns to analyze financial and operating performance. Management feels that these KPIs and benchmarks are key measures of profitability and overall sustainability for the Trust. These KPIs and benchmarks as presented do not have any standardized meaning prescribed by Canadian GAAP and therefore may not be comparable with the calculation of similar measures for other entities.

    NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

    September 30, 2009 and 2008
    (all tabular amounts in Cdn$ millions, except per unit amounts)

    1.  SUMMARY OF ACCOUNTING POLICIES

        The unaudited interim Consolidated Financial Statements follow the
        same accounting policies as the most recent annual audited financial
        statements, except as highlighted in Note 2. The interim Consolidated
        Financial Statement note disclosures do not include all of those
        required by Canadian generally accepted accounting principles
        ("GAAP") applicable for annual Consolidated Financial Statements.
        Accordingly, these interim Consolidated Financial Statements should
        be read in conjunction with the audited Consolidated Financial
        Statements included in the Trust's 2008 annual report.

    2.  NEW ACCOUNTING POLICIES

        Current Year Accounting Changes

        Effective January 1, 2009, the Trust adopted Section 3064, Goodwill
        and Intangible Assets issued by the Canadian Institute of Chartered
        Accountants ("CICA"). Section 3064 establishes standards for the
        recognition, measurement, presentation and disclosure of goodwill and
        intangible assets subsequent to its initial recognition. This new
        section has no current impact on the Trust or its Consolidated
        Financial Statements.

        This standard was adopted prospectively.

        Future Accounting Changes

        A. Business Combinations

        The CICA issued Handbook section 1582 "Business Combinations" that
        replaces the previous business combinations standard. Under this
        guidance, the purchase price used in a business combination is based
        on the fair value of shares exchanged at the market price at
        acquisition date. Under the current standard, the purchase price used
        is based on the market price of shares for a reasonable period before
        and after the date the acquisition is agreed upon and announced. In
        addition, the guidance generally requires all acquisition costs to be
        expensed. Current standards allow for the capitalization of these
        costs as part of the purchase price. This new Section also addresses
        contingent liabilities, which will be required to be recognized at
        fair value on acquisition, and subsequently remeasured at each
        reporting period until settled. Currently, standards require only
        contingent liabilities that are payable to be recognized. The new
        guidance requires negative goodwill to be recognized in earnings
        rather than the current standard of deducting from non-current
        assets in the purchase price allocation. This standard will be
        effective for the Trust on January 1, 2011, with prospective
        application.

        B. Consolidated Financial Statements and Non-controlling Interest

        The CICA issued Handbook Sections 1601 "Consolidated Financial
        Statements", and 1602 "Non-controlling Interests", which replaces
        existing guidance under Section 1600 "Consolidated Financial
        Statements". Section 1601 establishes standards for the preparation
        of Consolidated Financial Statements. Section 1602 provides guidance
        on accounting for a non-controlling interest in a subsidiary in
        Consolidated Financial Statements subsequent to a business
        combination. These standards will be effective for the Trust for
        business combinations occurring on or after January 1, 2011.

        C. Financial Instruments - Disclosures

        The CICA issued amendments to Handbook Section 3862, Financial
        Instruments - Disclosures. The amendments include enhanced
        disclosures related to the fair value of financial instruments and
        the liquidity risk associated with financial instruments. The
        amendments will be effective for annual financial statements for
        fiscal years ending after September 30, 2009. The amendments are
        consistent with recent amendments to financial instrument disclosure
        standards in International Financial Reporting Standards "IFRS". The
        Trust will include these additional disclosures in its annual
        Consolidated Financial Statements for the year ending December 31,
        2009.

    3.  CASH AND CASH EQUIVALENTS

        Cash equivalents are nil as at September 30, 2009 ($40 million in
        Canadian Treasury Bills as at December 31, 2008).

    4.  FINANCIAL ASSETS AND CREDIT RISK

        The majority of the credit exposure on accounts receivable at
        September 30, 2009 pertains to accrued revenue for September 2009
        production volumes. The Trust transacts with a number of oil and
        natural gas marketing companies and commodity end users ("commodity
        purchasers"). Commodity purchasers and marketing companies typically
        remit amounts to the Trust by the 25th day of the month following
        production. Joint interest receivables are typically collected within
        one to three months following production. At September 30, 2009, no
        one counterparty accounted for more than 25 per cent of the total
        accounts receivable balance and the largest commodity purchaser
        receivable balance is fully secured with Letters of Credit.

        In the third quarter of 2009, the Trust recorded a recovery of $0.4
        million for amounts received on balances previously included in the
        Trust's allowance for doubtful accounts. The Trust's allowance for
        doubtful accounts was $31.6 million as at September 30, 2009 and $32
        million as at December 31, 2008. During the first nine months of 2009
        the Trust did not record any additional provision for non-collectible
        accounts receivable.

        When determining whether amounts that are past due are collectable,
        management assesses the credit worthiness and past payment history of
        the counterparty, as well as the nature of the past due amount. ARC
        considers all amounts greater than 90 days to be past due. As at
        September 30, 2009, $6.9 million of accounts receivable are past due,
        excluding amounts described above, all of which are considered to be
        collectable.

        Maximum credit risk is calculated as the total recorded value of cash
        equivalents, accounts receivable, reclamation funds, and risk
        management contracts at the balance sheet date.

    5.  LONG-TERM DEBT

        Revolving Credit Facilities

        The Trust has an $800 million secured, annually extendible, financial
        covenant-based syndicated credit facility. The Trust also has in
        place a $25 million demand working capital facility. The working
        capital facility is secured and is subject to the same covenants as
        the syndicated credit facility.

        Borrowings under the syndicated credit facility bear interest at bank
        prime (2.25 per cent at September 30, 2009, four per cent at December
        31, 2008) or, at the Trust's option, Canadian dollar bankers'
        acceptances or U.S. dollar LIBOR loans, plus a stamping fee. At the
        option of the Trust, the lenders will review the syndicated credit
        facility each year and determine whether they will extend the
        revolving period for another year. In the event that the credit
        facility is not extended at any time before the maturity date, the
        loan balance will become repayable on the maturity date. The maturity
        date of the current syndicated credit facility is April 15, 2011. All
        drawings under the facility are subject to stamping fees. These
        stamping fees vary between a minimum of 60 basis points ("bps") to a
        maximum of 110 bps.

        As at September 30, 2009, the Trust had $1.9 million in letters of
        credit ($2 million in 2008), no subordinated debt, and was in
        compliance with all covenants.

        The payment of principal and interest are allowable deductions in the
        calculation of cash available for distribution to unitholders and
        rank ahead of cash distributions payable to unitholders. Should the
        properties securing this debt generate insufficient revenue to repay
        the outstanding balances, the unitholders have no direct liability

        Senior Secured Notes

        The fair value of senior secured notes as at September 30, 2009, is
        $349.3 million ($289.9 million as at December 31, 2008), and is
        calculated as the present value of principal and interest payments
        discounted at the Trust's credit adjusted risk free rate.

        Supplemental disclosures

        Amounts of US$16.4 million due under the senior secured notes and
        $14 million due under the Trust's working capital facility in the
        next 12 months have not been included in current liabilities as
        Management has the ability and intent to refinance this amount
        through the syndicated credit facility.

        Interest paid during the third quarter of 2009 was $4.8 million less
        than interest expense (equal in the third quarter of 2008).

        During the third quarter of 2009, the weighted-average interest rate
        under the credit facility was 0.9 per cent (3.6 per cent in 2008) and
        1.2 per cent for the nine months ended September 30, 2009 (four per
        cent in 2008).

        At September 30, 2009, the Trust had approximately $680 million of
        total unused credit available.

        The Trust's total long-term debt is secured in the form of a floating
        charge on all lands and assignments and a negative pledge on
        petroleum and natural gas properties.

        The Trust's weighted average credit adjusted risk free rate as at
        September 30, 2009 was 6.5 per cent (6.6 per cent as at December 31,
        2008).

    7.  CAPITAL MANAGEMENT

        The Trust's objective when managing its capital is to maintain a
        conservative structure that will allow the Trust to:

        -  Fund its development and exploration program;
        -  Provide financial flexibility to execute on strategic
           opportunities;
        -  Maintain a level of distributions that, in normal times, in the
           opinion of Management and the Board of Directors, is sustainable
           for a minimum period of six months in order to normalize the
           effect of commodity price volatility to unitholders; and
        -  Maintain a level of distributions which will transfer tax
           liabilities to unitholders and minimize taxes paid by the Trust.

        The Trust manages the following capital:

        -  Trust units and exchangeable shares;
        -  Long-term debt; and
        -  Working capital (defined as current assets less current
           liabilities excluding risk management contracts and future income
           taxes).

        When evaluating the Trust's capital structure, management's objective
        is to limit net debt to less than 2.0 times annualized cash flow from
        operating activities and 20 per cent of total capitalization. As at
        September 30, 2009 the Trust's net debt to annualized cash flow from
        operating activities ratio is 1.5 and its net debt to total
        capitalization ratio is 12.8 per cent.

        The Trust manages its capital structure and makes adjustments to it
        in response to changes in economic conditions and the risk
        characteristics of the underlying assets. The Trust is able to change
        its capital structure by issuing new trust units, exchangeable
        shares, new debt or changing its distribution policy.

        In addition to internal capital management the Trust is subject to
        various covenants under its credit facilities. Compliance with these
        covenants is monitored on a quarterly basis and as at September 30,
        2009 the Trust is in compliance with all covenants. Refer to Note 5
        for further details.

    8.  MARKET RISK MANAGEMENT

        The Trust is exposed to a number of market risks that are part of its
        normal course of business. The Trust has a risk management program in
        place that includes financial instruments as disclosed in the risk
        management section of this note.

        ARC's risk management program is overseen by its Risk Committee based
        on guidelines approved by the Board of Directors. The objective of
        the risk management program is to support the Trust's business plan
        by mitigating adverse changes in commodity prices, interest rates and
        foreign exchange rates.

        In the sections below, ARC has prepared sensitivity analyses in an
        attempt to demonstrate the effect of changes in these market risk
        factors on the Trust's net income. For the purposes of the
        sensitivity analyses, the effect of a variation in a particular
        variable is calculated independently of any change in another
        variable. In reality, changes in one factor may contribute to changes
        in another, which may magnify or counteract the sensitivities. For
        instance, trends have shown a correlation between the movement in the
        foreign exchange rate of the Canadian dollar to the U.S. dollar and
        the West Texas Intermediate posting ("WTI") crude oil price.

        Commodity price risk

        The Trust's operational results and financial condition, and
        therefore the amount of distributions paid to unitholders, are
        largely dependent on the commodity prices received for oil and
        natural gas production. Commodity prices have fluctuated widely
        during recent years due to global and regional factors including
        supply and demand fundamentals, inventory levels, weather, economic,
        and geopolitical factors. Movement in commodity prices could have a
        significant positive or negative impact on distributions to
        unitholders.

        ARC manages the risks associated with changes in commodity prices by
        entering into a variety of risk management contracts (see Risk
        Management Contracts below). The following table illustrates the
        effects of movement in commodity prices on net income due to changes
        in the fair value of risk management contracts in place at September
        30, 2009. The sensitivity is based on a $15 increase and $15 decrease
        in the price of US$ WTI crude oil and a $2 increase and $2 decrease
        in the price of Cdn$ AECO natural gas. The commodity price
        assumptions are based on Management's assessment of reasonably
        possible changes in oil and natural gas prices that could occur
        between September 30, 2009 and the Trust's next reporting date.

        ---------------------------------------------------------------------
                    Increase in Commodity Price  Decrease in Commodity Price
        ---------------------------------------------------------------------
        ($ millions)  Crude oil     Natural gas     Crude oil    Natural gas
        ---------------------------------------------------------------------
        Net income
         (decrease)
         increase         (12.2)           (8.1)         18.1           14.4
        ---------------------------------------------------------------------

        As noted above, the sensitivities are hypothetical and based on
        Management's assessment of reasonably possible changes in commodity
        prices between the balance sheet date and the Trust's next reporting
        date. The results of the sensitivity should not be considered to be
        predictive of future performance. Changes in the fair value of risk
        management contracts cannot generally be extrapolated because the
        relationship of change in certain variables to a change in fair value
        may not be linear.

        Interest Rate Risk

        The Trust has both fixed and variable interest rates on its debt.
        Changes in interest rates could result in a significant increase or
        decrease in the amount the Trust pays to service variable interest
        rate debt, potentially impacting distributions to unitholders.
        Changes in interest rates could also result in fair value risk on the
        Trust's fixed rate senior secured notes. Fair value risk of the
        senior secured notes is mitigated due to the fact that the Trust does
        not intend to settle its fixed rate debt prior to maturity.

        If interest rates applicable to floating rate debt at September 30,
        2009 were to have increased by 50 bps (0.5 per cent) it is estimated
        that the Trust's net income would decrease by $1.1 million.
        Management does not expect interest rates to decrease.

        Foreign Exchange Risk

        North American oil and natural gas prices are based upon U.S. dollar
        denominated commodity prices. As a result, the price received by
        Canadian producers is affected by the Canadian/U.S. dollar exchange
        rate that may fluctuate over time. In addition the Trust has U.S.
        dollar denominated debt of which future cash repayments are directly
        impacted by the exchange rate in effect on the repayment date.

        Variations in the Canadian/U.S. dollar exchange rate could also have
        a significant positive or negative impact on distributions to
        unitholders.

        As at September 30, 2009 no risk management contracts pertaining to
        foreign exchange were outstanding.

        If foreign exchange rates applicable to U.S. denominated debt were to
        have increased or decreased by $0.10Cdn$/US$ it is estimated that the
        Trust's net income for the period ended September 30, 2009 would
        decrease or increase by $27 million, respectively. Increases and
        decreases in foreign exchange rates applicable to US$ payables and
        receivables would have a nominal impact on the Trust's net income for
        the period ended September 30, 2009.

        Risk Management Contracts

        The Trust uses a variety of derivative instruments to reduce its
        exposure to fluctuations in commodity prices, foreign exchange rates,
        interest rates and power prices. The Trust considers all of these
        transactions to be effective economic hedges; however, the majority
        of the Trust's contracts do not qualify as effective hedges for
        accounting purposes.

        Following is a summary of all risk management contracts in place as
        at September 30, 2009 that do not qualify for hedge accounting:

        At September 30, 2009, the fair value of the contracts that were not
        designated as accounting hedges was a loss of $4.5 million. The Trust
        recorded a gain on risk management contracts of $13.2 million in the
        statement of income for the nine months ended September 30, 2009
        ($82.5 million loss in 2008). This amount includes the realized and
        unrealized gains and losses on risk management contracts that do not
        qualify as effective accounting hedges.

        The following table reconciles the movement in the fair value of the
        Trust's financial risk management contracts that have not been
        designated as effective accounting hedges:

        ---------------------------------------------------------------------
        (1) Intrinsic value of risk management contracts not designated as
            effective accounting hedges equals a loss of $8.6 million at
            September 30, 2009 ($24.7 million loss at September 30, 2008).

        During 2007 the Trust entered into treasury rate lock contracts in
        order to manage the Trust's interest rate exposure on future debt
        issuances. During 2008 it was determined that the previously
        anticipated debt issuance was no longer expected to occur and the
        associated treasury rate lock contracts were unwound at a loss of
        $13.6 million. The loss was reclassified from Other Comprehensive
        Income ("OCI"), net of tax $10 million and recognized in net income.

        The Trust's electricity contracts are intended to manage price risk
        on electricity consumption. Portions of the Trust's financial
        electricity contracts were designated as effective accounting hedges
        on their respective contract dates. A realized loss of $0.3 million
        and $1.1 million for the three and nine months ended September 30,
        2009 (gain of $0.7 million and $2.8 million respectively in 2008) has
        been included in operating costs on these electricity contracts. The
        accumulated unrealized fair value loss of $0.3 million on these
        contracts has been recorded on the Consolidated Balance Sheet at
        September 30, 2009 with the movement in fair value recorded in OCI,
        net of tax. The fair value movement for the nine months ended
        September 30, 2009 is an unrealized loss of $3.6 million. As at
        September 30, 2009 $0.2 million of the unrealized fair value loss is
        attributed to contracts that will settle over the next twelve months.

        The following table reconciles the movement in the fair value of the
        Trust's financial risk management contracts that have been designated
        as effective accounting hedges:

        All of the Trust's risk management contracts are transacted in liquid
        markets; fair values are determined using a valuation model based on
        published, third party, and market based price and rate information.

        (1) Weighted average trust units exclude trust units issuable for
            exchangeable shares.
        (2) Diluted trust units include trust units issuable for outstanding
            exchangeable shares at the year-end exchange ratio.
        (3) There are no rights outstanding as of September 30, 2009 and
            therefore, no dilutive impact. Previously outstanding rights were
            dilutive and therefore were included in the diluted unit
            calculation for 2008.

        Basic net income per unit has been calculated based on net income
        after non-controlling interest divided by weighted average trust
        units. Diluted net income per unit has been calculated based on net
        income before non-controlling interest divided by diluted trust
        units.

    12. RECONCILIATION OF CASH FLOW FROM OPERATING ACTIVITIES AND
        DISTRIBUTIONS

        Distributions are calculated in accordance with the Trust Indenture.
        To arrive at distributions, cash flow from operating activities is
        reduced by reclamation fund contributions including interest earned
        on the funds, a portion of capital expenditures and, when applicable,
        debt repayments. The portion of cash flow from operating activities
        withheld to fund capital expenditures and to make debt repayments is
        at the discretion of the Board of Directors.

    13. WHOLE TRUST UNIT INCENTIVE PLAN

        Compensation expense associated with the Whole Trust Unit Incentive
        Plan ("the Whole Unit Plan") is granted in the form of Restricted
        Trust Units ("RTUs") and Performance Trust Units ("PTUs") and is
        determined based on the intrinsic value of the Whole Trust Units at
        each period end.

        The Trust recorded non-cash compensation recovery of $4 million and
        $0.1 million to general and administrative and operating expenses,
        respectively, and capitalized $0.7 million to property, plant and
        equipment in the nine months ended September 30, 2009 for the
        estimated change in the Plan liability ($4.6 million, $0.5 million,
        and $1.1 million for the nine months ended September 30, 2008). The
        non-cash compensation recovery was based on the September 30, 2009
        unit price of $20.20 ($23.10 at September 30, 2008), accrued
        distributions, a performance multiplier, and the estimated number of
        units to be issued on maturity.

        The following table summarizes the RTU and PTU movement for the nine
        months ended September 30, 2009:

        During the first nine months of 2009, cash payments of $16.6 million
        were made to employees relating to the Whole Unit Plan compared to
        $18.3 million in 2008. In October 2008, vesting periods were revised
        from April and October to March and September of each year
        commencing in 2009.
