(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 first quarter of 2009 would be
$116.6 million ($0.51 per unit). Distributions as a percentage of
Cash Flow would be 70 per cent for the first quarter of 2009. Please
refer to the non-GAAP measures section in the MD&A for further
details.
(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 first quarter of 2009, includes 0.9 million (1.2 million in
2008) exchangeable shares exchangeable into 2.577 trust units (2.314
in 2008) each for an aggregate 2.4 million (2.7 million in 2008)
trust units.
(7) Includes trust units issuable for outstanding exchangeable shares at
period end.

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

- The Trust completed an equity offering of 15.5 million trust units at
$16.35 per unit for net proceeds of $240 million during the quarter.
Proceeds of the offering were applied against the Trust's debt
resulting in a net debt balance of $781.5 million at March 31, 2009,
a reduction of $180.4 million from year end.

- On April 14, 2009, the Trust announced the closing of a private
placement of long-term debt in the form of senior secured notes
totaling US$125 million at a blended average interest rate of 7.47
per cent. The notes were offered in three tranches with repayment
dates between 2012 and 2021 allowing the Trust to convert a portion
of its credit facility debt to long term notes that mature over a
number of years as opposed to being re-financed all in one year.
Proceeds from the notes were used to reduce the debt outstanding on
the Trust's $800 million credit facility to $356 million, providing
the Trust with $444 million of undrawn debt capacity on the bank
line. The Trust also has $167 million available to it through the
undrawn portion of a shelf facility with a large insurance company.

- The Trust executed a $97.2 million capital expenditure program in the
first quarter of 2009 that included drilling 81 gross wells on
operated properties, resulting in 14 oil wells, 66 natural gas wells
and a 99 per cent success rate. Of the 81 wells drilled in the first
quarter, the Trust currently has 33 wells waiting on tie-in, of which
24 wells are awaiting completion. The capital expenditures were
64 per cent funded by cash flow from operating activities and
proceeds from the DRIP program and the remaining portion was funded
through debt.

- Production for the quarter was on budget at 64,872 boe per day with
record production at Dawson and Ante Creek. With the reduction in the
2009 capital budget, the Trust now expects full year production to
average between 62,000 and 64,000 boe per day at an operating cost of
approximately $10.70 per boe.

- In light of the weak commodity price environment, particularly
for natural gas, the monthly distribution has been decreased to
$0.10 per unit effective with the May distribution payable on
June 15, 2009. The Board has also approved a reduced capital
expenditure budget for the Trust of $350 million while affirming its
commitment to the construction of a 60 mmcf per day gas plant to be
completed late in the first quarter of 2010 for the Dawson field
contingent on the timely receipt of regulatory approvals.

- The Trust's current plans are to convert to a dividend paying
Corporation effective December 31, 2010. At this time,
management believes that this will be most logical and tax efficient
alternative for ARC unitholders. The potential conversion will be
subject to regulatory and unitholder approval.

- Montney Resource Play Development

During the first quarter of 2009, the Trust spent $36.3 million on
development activities in the Dawson area including the drilling of
five horizontal wells, two of which were completed and tested during
the quarter. Vertical wells were also drilled at Sundown and Pouce
Coupe.

With the completion of a third party compressor in the middle of
February, total production from the Dawson area grew to an average of
51.2 mmcf per day in the first quarter of 2009 and exited the quarter
at approximately 56 mmcf per day.

The Trust continues to work towards a late first quarter 2010
completion date for a new 60 mmcf per day gas plant for Dawson.
Design work is complete, long-lead time items have been ordered and
the public notification has been completed. Applications have
been submitted to the appropriate regulatory agencies and are
currently under review.

- Enhanced Oil Recovery Initiatives

During the first quarter, the Trust spent $7 million on enhanced oil
recovery ("EOR") initiatives. The Redwater CO(2) pilot project is
well underway and on schedule with the highlight of the quarter being
the start-up of the associated production facility. The Trust
expects that it will take at least until 2010 before it will
know to what extent the pilot has been successful in increasing oil
production. While the pilot project may indicate enhanced recovery,
the current outlook for crude oil prices and the cost and
availability of CO(2) may hinder the Trust's ability to achieve
commercial viability for a full scale EOR scheme.

MANAGEMENT'S DISCUSSION AND ANALYSIS
------------------------------------

management's analysis of its financial performance and significant trends or
external factors that may affect future performance. It is dated May 5, 2009
and should be read in conjunction with the unaudited Consolidated Financial
Statements for the period ended March 31, 2009 and the audited Consolidated
Financial Statements and MD&A as at and for the year ended December 31, 2008
as well as the Trust's Annual Information Form that is filed on SEDAR at
www.sedar.com.
The MD&A contains Non-GAAP measures and forward-looking statements and
readers are cautioned that the MD&A should be read in conjunction with the
Trust's disclosure under "Non-GAAP Measures" and "Forward-Looking Statements"
included at the end of this MD&A.

Executive Overview

ARC Energy Trust ("ARC") is one of the top 20 producers of conventional
oil and gas in western Canada. As at March 31, 2009, ARC held interests in
excess of 18,600 wells with approximately 5,600 wells operated by ARC and the
remainder operated primarily 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 March 31, 2009 was $4.1 billion as shown on
Table 22.
ARC's objective as an energy company is to provide superior and
sustainable long-term returns to unitholders. Key attributes of the business
plan include:

<<
- Concentrated activities in three major business areas: conventional
oil and natural gas assets, resource plays and enhanced oil recovery
initiatives. In addition to these major initiatives, ARC continually
reviews acquisition and disposition opportunities to high-grade its
asset base and provide future growth opportunities.

- Pay a portion of cash flow to unitholders. Currently the Trust
distributes $0.12 per unit per month but due to current oil and
natural gas prices the distribution amount has been decreased to
$0.10 per unit per month starting with the May distribution to be
paid on June 15, 2009. 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 March 31,
2009, the Trust has distributed $3.3 billion or $24.06 per unit.

- Declining commodity prices have caused management to defer some
2009 capital projects to future periods resulting in a reduced
capital budget of $350 million for 2009. A key focus is to
construct a gas plant at Dawson and expand production from the
Montney. Approximately half of ARC's $350 million capital program
will support this key initiative. The remaining capital is targeted
at key assets across western Canada. Calculated on a boe basis,
normalized production per thousand units has decreased slightly from
0.30 to 0.27 while the Trust has made distributions of $5.43 per
unit or $1.15 billion from January 1, 2007 through to March 31, 2009.
Details of the calculations for normalized production and reserves
per unit are provided in Table 1.

- The periodic acquisition of strategic producing and undeveloped
properties to enhance current production or provide the potential for
future drilling locations and if successful, additional production
and reserves.

- Use prudent production practices to maximize the recovery of oil and
natural gas from the reservoirs.

- Operational excellence for both routine operating expenditures and
costs incurred for capital projects. In the current environment ARC
is aggressively pursuing cost reductions throughout the business. ARC
expects that the aggregate amount of operating costs will increase
over time as ARC adds approximately 300 wells per year to its
operating base to replace the natural decline on existing producing
wells.

ARC's business plan and operating practices also include the following
strategies and action plans that are being undertaken to increase ARC's
competitiveness and future profitability:

- Continual development of staff expertise and the hiring and retention
of some of the industry's best and most qualified personnel.

- Building relationships with suppliers, joint venture partners,
government and other stakeholders and conducting business in a fair
and equitable manner.

- Reviewing the corporate structure in order to optimize returns to
investors with the commencement of the trust taxation on January 1,
2011. ARC's most likely course of action will be to convert to a
corporation, subject to unitholder approval.

- Promoting the use of proven and effective technologies to enhance the
recoverable resources in place and reduce costs.

- Being an industry leader in health, safety and environmental
performance.

- Actively supporting local initiatives and charities in the
communities in which the Trust's employees live and work.

(1) Normalized indicates that all years 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 annual per unit values.
(2) Production per unit represents daily average production (boe) per
thousand trust units. 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) divided by period end trust units outstanding
including trust units issuable for exchangeable shares.

ARC's business plan has achieved significant operational success. However,
commodity prices and the current economic crisis are significant factors
determining profitability of ARC and capital appreciation of our trust units
in the market place. The negative impact of external factors has led to a
negative return for the trailing one and three years despite the successful
execution of ARC's business plan and operational successes.

The 2009 Guidance provides unitholders with information on management's
expectations for results of operations for 2009. Readers are cautioned that
the 2009 Guidance may not be appropriate for other purposes.
The following revisions have been made to the Trust's 2009 guidance.

- Production levels have been revised as a result of the Trust's
reduction in capital expenditures discussed below. The Trust now
expects that 2009 full year production will be in the range of 62,000
to 64,000 boe per day. Production guidance numbers for 2010 are under
review and will change due to the impact of decreased capital
expenditures in 2009 and the current uncertainty with regards to
capital plans for 2010.

- Transportation expenses have been revised downward to $1.00 per boe.
Initial guidance was based on expectations of increased oil
transportation charges resulting from apportionment on the main
Enbridge pipeline as well as reduced capacity on the Saskatchewan
Enbridge pipeline. These restrictions have not materialized year-to-
date and therefore the Trust has re-forecast full year transportation
expense to be approximately $1.00 per boe.

- G&A expenses are expected to decrease to $2.10 per boe most
significantly as a result of a decrease in the costs for the Trust's
Whole Unit Plan. The cash whole unit plan expense is expected to
decrease from $0.85 per boe to $0.55 per boe based on the reduction
of the trust unit price and distributions in 2009. The non-cash whole
unit plan expense is expected to decrease from an expense of $0.15
per boe to a recovery of $0.20 per boe as the cash payout in March
2009 was based on an actual price of $12.18 per unit as compared to
the $20.10 that was accrued for this payment at year-end 2008. Cash
G&A costs, excluding the whole unit plan expense for the full year
2009 are expected to decrease to $1.75 from $1.80 as a result of a
reduction in variable compensation costs.

- Interest expense has been revised downward to reflect the lower
interest rates on the Trust's floating rate debt as well as the
Trust's lower debt balance subsequent to the equity offering
completed in February 2009. These amounts will be partially offset by
higher interest rates on the Trust's new senior secured long-term
notes issued in April 2009 that have a blended average interest rate
of 7.47 per cent. See Capitalization, Financial Resources and
Liquidity section of this MD&A for details.

- Capital Expenditures have been revised downward to $350 million from
the previous guidance of $450 million. The Trust has re-evaluated all
capital projects in light of the ongoing challenges with low
commodity prices. The key focus for the 2009 capital program remains
in the Montney area. For the full year 2009, the Trust plans to
drill 122 gross wells on operated properties as compared to 191
gross wells that were planned under the $450 million capital
expenditure guidance. Items that have been deferred until 2010
include a 75 well shallow gas drilling program in the Brooks area,
three horizontal wells in the Redwater area and four horizontal
wells and two vertical wells in the Dawson area. The Trust is
anticipating potential cost savings on the planned capital
expenditures for the remainder of 2009 which, if realized, may
create an opportunity to fund additional strategic projects. In
addition, the Trust is currently evaluating the Alberta government's
corporate royalty drilling credit program that was announced on
March 3, 2009 in order to assess the viability of additional capital
programs using the revised royalty rates.

2009 First Quarter Financial and Operational Results

year-end.
(2) Based on net income after non-controlling interest divided by
weighted average trust units outstanding excluding trust units
issuable for exchangeable shares.
(3) Based on number of trust units outstanding at each cash distribution
date.
(4) Reported production amount is based on company interest before
royalty burdens. Where applicable in this MD&A natural gas has been
converted to barrels of oil equivalent ("boe") based on 6 mcf: 1 bbl.
The boe rate is based on an energy equivalent conversion method
primarily applicable at the burner tip and does not represent a value
equivalent at the well head. Use of boe in isolation may be
misleading.

Net Income

As a result of decreased commodity prices, the Trust's net income and cash
flows were negatively impacted during the first quarter. Net income in the
first quarter of 2009 was $22.3 million ($0.10 per unit), a decrease of $59
million from $81.3 million ($0.39 per unit) in the first quarter of 2008. The
decrease in net income is largely attributed to the $85.6 million decrease in
cash flow from operating activities from the first quarter of 2008 (see Table
6 for details), along with the following non-cash items:

- The Trust recorded a $12.1 million non-cash recovery for its long-
term incentive whole unit plan that increased net income in the first
quarter of 2009 compared to an expense of $13.8 million for the same
period of 2008. (See - General and Administrative Expenses and Trust
Unit Incentive Compensation for details)

- The Trust recorded a future income tax recovery of $12.2 million that
increased net income in the first quarter of 2009 compared to a
future tax expense of $0.5 million for the first quarter of 2008.

- The Trust recorded a $6.6 million non-cash loss on risk management
contracts in the first quarter of 2009 compared to a loss of
$18.7 million recorded in the same period of 2008. (See - Risk
Management and Hedging Activities for details).
>>

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 annual shortfall of distributions to
net income as a measure of long-term sustainability.

Production

Production volumes averaged 64,872 boe per day in the first quarter of
2009 compared to 66,976 boe per day in the same period of 2008 as detailed in
Table 8. In the first quarter of 2008, the Trust recorded a 1,000 boe per day
natural gas volume adjustment due to prior period measurement errors at the
Ante Creek property made by the facility operator. In the first quarter of
2009, the Trust has posted record production in the Ante Creek and Dawson
areas helping to offset declines in shallow gas production in southeast
Alberta and southwest Saskatchewan. New production in the Delburne area from
the Trust's natural gas from coal drilling program was also realized in the
first quarter of 2009.

Light and medium crude oil production remained constant at 27,720 boe per
day compared to 27,718 boe per day in 2008, while heavy oil production
declined by 19 per cent. Natural gas production was 193.8 mmcf per day in the
first quarter of 2009, a decrease of five per cent from the 204.3 mmcf per day
produced in the first quarter of 2008.
The Trust's objective is to maintain annual production through the
drilling of wells and other development activities. In fulfilling this
objective, there may be fluctuations in production depending on the timing of
new wells coming on-stream. During the first quarter of 2009, the Trust
drilled 81 gross wells (57 net wells) on operated properties; 14 gross oil
wells, and 66 gross natural gas wells with a 99 per cent success rate.
The Trust expects that 2009 full year production will be approximately
62,000 to 64,000 boe per day and that 122 gross wells (101 net wells) 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
2,000 to 3,000 boe per day. The planned capital expenditures are being
continuously monitored in the context of the current economic environment and
will be revised as required.

Revenue

Revenue decreased to $225.2 million in the first quarter of 2009, $182.7
million lower than 2008 revenues of $407.9 million. While oil volumes were
relatively unchanged year over year, the decrease in realized oil prices
accounted for a $116.9 million decrease in revenues. Natural gas revenue
decreased by $54.4 million, comprising a $48.4 million decrease due to lower
prices realized in 2009 and a $6 million decrease due to lower volumes
produced in 2009.
A breakdown of revenue is outlined in Table 10:

The sharp decline in oil prices during the fourth quarter of 2008
continued into the first quarter of 2009. US$WTI prices averaged $43.21
throughout the first quarter of 2009, a 56 per cent decrease from the
comparable period in 2008. This dramatic decrease was partially offset by the
weakening of the Canadian dollar compared to the U.S. dollar, however,
widening of the price differentials for the first part of the quarter 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 $46.44 per boe, a 48 per cent reduction
over the first quarter 2008 realized price of $89.72 per boe.
Alberta AECO Hub natural gas prices, which are commonly used as an
industry reference, averaged $5.64 per mcf in the first quarter of 2009
compared to $7.13 per mcf in the same period of 2008. ARC's realized gas
price, before hedging, decreased by 33 per cent to $5.20 per mcf compared to
$7.80 per mcf in the first 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. While natural gas prices softened
in the first quarter of 2009 compared to the fourth quarter of 2008, prices
have continued to decline in the second quarter with posted prices at
approximately $3.30 per mcf for the month of April with no improvement
expected in the near term as a result of record storage volumes and concern
over the state of the North American economy. Unitholders should expect
further deterioration in natural gas revenue in the second quarter and likely
into the third quarter.
Prior to hedging activities, ARC's total realized commodity price was
$38.40 per boe in the first quarter of 2009, a 42 per cent decrease from the
$66.67 per boe received prior to hedging in the first 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 first quarter of 2009 resulted in
realized cash gains of $13.5 million on natural gas risk management contracts.
Realized cash losses of $1.9 million were recorded on the Trust's crude oil
risk management contracts as a result of premiums paid in the first quarter of
2009.
During the first quarter of 2009 the Trust realized a cash gain of $4.5
million due to the unwinding of an interest rate swap risk management contract
that converted a portion of the Trust's fixed rate debt to floating rate debt.
ARC's first quarter 2009 results include an unrealized total
mark-to-market loss of $6.6 million with a net unrealized mark-to-market loss
position of $3.1 million as at March 31, 2009. The net loss position is mostly
attributed to losses on the Trust's power and interest contracts. The
mark-to-market values represent the market price to buy-out the Trust's
contracts as of March 31, 2009 and may differ from what will eventually be
realized.
Table 12 summarizes the total gain (loss) on risk management contracts
for the year-over-year change as of the first quarter of 2009:

the Consolidated Statement of Comprehensive Income and Accumulated
Other Comprehensive Income.

The Trust currently limits the amount of forecast production that can be
hedged to a maximum 50 per cent with the remaining 50 per cent of production
being sold at market prices. The following table is an indicative summary of
the Trust's positions for crude oil and natural gas as at March 31, 2009.

(1) The prices and volumes noted above represents 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, as well as a fixed price swap for crude oil for
the month of April 2009. Please refer to note 9 in the Notes to the
Consolidated Financial Statements for full details of the Trust's
risk management positions as of March 31, 2009.

Table 13 should be interpreted as follows using the second quarter 2009
natural gas 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 $4.50, ARC will receive $5.38 less the
difference between $4.50 and the market price on 20,000 GJ per day.
For example if the market price is $4.45, the Trust will receive
$5.33 on 20,000 GJ per day.
- If the market price is between $4.50 and $5.38, ARC will receive
$5.38 on 40,000 GJ per day.
- If the market price is between $5.38 and $6.50, ARC will receive the
market price on 40,000 GJ per day.
- If the market price exceeds $6.50, ARC will receive $6.50 on
40,000 GJ per day.

Operating Netbacks

The Trust's operating netback, before realized hedging gains and losses,
decreased 53 per cent to $21.16 per boe in the first quarter of 2009 compared
to $44.81 per boe in same period of 2008. The decrease in netbacks is due most
significantly to the reduced commodity prices in the period as well as higher
operating costs and transportation costs and was partially offset by lower
royalties corresponding to the lower commodity prices.
The Trust's first quarter 2009 netback, after realized hedging gains and
losses, was $23.13 per boe, a 45 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 contracts during the quarter of $1.79 per boe compared to a
net loss of $2.63 per boe recorded for the same period in 2008.
The components of operating netbacks are summarized in Table 14:

(1) Operating expenses are composed of direct costs incurred to operate
oil and gas wells. A number of assumptions have been made in
allocating these costs between oil, heavy oil, natural gas and
natural gas liquids production.
>>

Royalties as a percentage of pre-hedged commodity revenue net of
transportation decreased to 17 per cent ($6.34 per boe) in the first quarter
of 2009 compared to 18 per cent ($11.85 per boe) in 2008. The Alberta
Government's New Royalty Framework ("Framework" or "NRF") was effective
January 1, 2009 which resulted in an overall decrease in the Trust's royalties
that was in line with management's expectations due to the low commodity price
environment. The Trust continues to evaluate the amendments to the new royalty
framework in order to determine the optimal elections that should be made by
the Trust. See Alberta Government New Royalty Framework.
Operating costs increased to $10.12 per boe compared to $9.55 per boe in
the first quarter of 2008. Total operating costs increased $0.9 million, or
two per cent in the first quarter of 2009. There is a high fixed operating
cost component for the Trust's properties resulting in a trend of increased
operating costs on a per boe basis as production declines over time. The Trust
estimates that full year 2009 operating costs will be approximately $245
million or approximately $10.70 per boe based on annual production of
approximately 62,000 to 64,000 boe per day. This includes a six per cent
increase for costs associated with the increase in total operated wells in
2009 as compared to 2008.

Alberta Government New Royalty Framework

On April 10, 2008, the Alberta Government announced revisions to the
Framework that was legislated in November 2008 and took effect on January 1,
2009.
The revisions to the Framework include the following:

<<
- Increased royalty rates on conventional and non-conventional oil and
natural gas production in Alberta whereby royalty rates may increase
to a maximum rate of 50 per cent;

- Sliding scale royalty calculations based on a broader range of
commodity prices whereby conventional oil and natural gas royalty
rates may increase up to maximum prices of approximately Cdn$120 per
barrel and Cdn$16 per GJ, respectively;

- The elimination of royalty incentive and royalty holiday programs
with the exception of specific programs relating to deep oil and
natural gas drilling programs, innovative technology and enhanced
recovery programs;
>>

Subsequent to legislation of the NRF, the Alberta Government introduced
the Transitional Royalty Plan ("TRP") in response to the anticipated decrease
in Alberta development activity resulting from the economic downturn and
declining commodity prices. The TRP offers reduced royalty rates for new wells
drilled on or after November 19, 2008 through December 31, 2013 that meet
certain depth criteria. The TRP is in place for a maximum period of five years
to December 31, 2013; all wells will convert to the NRF on January 1, 2014.
The TRP is an "elective plan" whereby an election must be filed on an
individual well basis to qualify for the TRP. The Trust does not anticipate a
significant benefit from the TRP in 2009 as the majority of the Trust's wells
converted to the NRF on January 1, 2009.
On March 3, 2009, the Alberta Government announced the Energy Incentive
Program ("EIP") in response to the decrease in energy related development
activity in the province. The incentive program will work in tandem with the
NRF and the TRP and includes the following key elements:

<<
- Drilling Royalty Credit - producers will receive a drilling credit
for new wells drilled between April 1, 2009 and March 31, 2010. The
drilling credit is based on a $200 per meter credit on total meters
drilled, however the maximum drilling credit is limited to
10 per cent of 2008 Alberta Crown Royalties paid for companies
producing greater than 25,000 boe per day in Alberta. ARC's estimated
maximum total drilling credit would be approximately $15 million. The
drilling credit will be applied to reduce Alberta Crown Royalties
payable in 2009 and 2010.

- New Well Incentive Program - new production brought on-stream between
April 1, 2009 and March 31, 2010 will qualify for a five per cent
Alberta Crown Royalty rate for a period of 12 months subject to
volume caps of 50,000 barrels of crown oil production and 150 Mmcf of
crown natural gas production.
>>

Approximately 65 per cent of the Trust's production is in Alberta;
consequently, the Framework including the TRP and EIP will have a significant
impact on the Trust's Alberta and corporate royalty rates. The Trust has
completed an assessment of the Framework and has estimated that the Trust's
average corporate royalty rate will change from approximately 18 per cent of
revenue in 2008 to between 14 and 25 per cent of revenue in 2009 depending
upon commodity prices as illustrated in Table 15 and the value of incentives
realized in 2009.

General and Administrative Expenses and Trust Unit Incentive Compensation

G&A net of overhead recoveries on operated properties increased 11 per
cent to $10.3 million in the first quarter of 2009 from $9.3 million in 2008.
Increases in G&A expenses for 2009 were a result of increased staff costs
based on a ten per cent increase in the G&A staff levels on average in the
first quarter of 2009 when compared to the same period in 2008.
The Trust paid out $7.6 million under the Whole Trust Unit Incentive Plan
("Whole Unit Plan") in the first quarter of 2009 of which $5.6 million was
allocated to G&A with the remainder to operating costs and property, plant and
equipment. There were no cash payments made under the Whole Unit Plan in the
first quarter of 2008, the vesting date occurred in April and as such a $14.5
million cash expense was recorded in the second quarter financial results in
2008. The next cash payment under the Whole Unit Plan is scheduled to occur in
September 2009.

A non-cash trust unit incentive compensation recovery ("non-cash
compensation recovery") of $10.8 million ($1.85 per boe) was recorded in the
first quarter of 2009 compared to an expense of $11.9 million ($1.95 per boe)
in 2008. The recovery in 2009 relates in part to a reversal of the accrual for
the cash payment made in the quarter as well as a reduction in the liability
for the units outstanding at March 31, 2009 due to the reduction in the trust
unit price relative to the closing price of the trust units at December 31,
2008. The 2008 non-cash amount relates to estimated costs of the Whole Unit
Plan to March 31, 2008 as there were no cash payments during the first quarter
of 2008 and therefore no reversals were recorded in the period.

Whole Unit Plan

The Whole Unit Plan results in each employee, officer and director (the
"plan participants") receiving 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 17 shows the changes to the Whole Unit Plan during the first three
months of 2009 along with the estimated value of the plan at March 31, 2009:

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.

price environment, the monthly distribution has decreased from $0.12
per unit to $0.10 per unit starting with the distribution declared
for the month of May and payable on June 15, 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 $16.8 million and $56.9 million will be paid out from
2009 through 2012 based on the current trust unit price, distribution levels
and the Trust's market performance relative to its peers.

Interest Expense

Interest expense decreased to $5.8 million in the first quarter of 2009
from $8.8 million in 2008 due to a decrease in short-term interest rates. As
at March 31, 2009, the Trust had $703.8 million of debt outstanding, of which
$267.2 million was fixed at a weighted average rate of 5.1 per cent and $436.6
million, including the working capital facility, was floating at current
market rates plus a credit spread of 60 basis points. Seventy-two per cent (US
$404.5 million) of the Trust's debt is denominated in U.S. dollars.

Foreign Exchange Gains and Losses

The Trust recorded a loss of $14.6 million in the first quarter of 2009
on foreign exchange transactions compared to a loss of $15 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. The 2009 realized foreign exchange loss of $0.2 million relates
to interest payments and hedging settlements in the quarter.
Unrealized foreign exchange gains and losses are due to revaluation of
U.S. denominated debt balances. The volatility of the Canadian dollar during
the reporting period has a direct impact on the unrealized component of the
foreign exchange gain or loss. The unrealized gain or loss impacts net income
but does not impact cash flow from operating activities as it is a non-cash
amount. From December 31, 2008 to March 31, 2009, the Cdn$/US$ exchange rate
increased from 1.22 to 1.26 resulting in an unrealized loss of $14.4 million
on U.S. dollar denominated debt.

Taxes

In the first quarter of 2009, a future income tax recovery of $12.2
million was included in income compared to an expense of $0.5 million in 2008.
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 first 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 and the Board of Directors continue to review the impact of
the SIFT rules on our business strategy and while there has not been a final
decision as to ARC's future direction at this time we are of the opinion that
the conversion from a trust to a corporation may be the most logical and tax
efficient alternative for ARC unitholders.
A conversion to a corporation will require approval of ARC's unitholders,
as well as customary court and regulatory approvals. We currently anticipate
that the closing of a conversion would occur on or before December 31, 2010.
This would require a unitholder meeting to be scheduled for early to
mid-December 2010. To be implemented, a conversion must be approved by not
less than two-thirds of the votes cast by unitholders voting at the meeting.
The intention would be for a conversion to be tax deferred for Canadian and
U.S. income tax purposes.
For Canadian GAAP, we anticipate that the conversion would be accounted
for on a continuity of interests basis. Under the continuity of interests
method of accounting, the corporation would be recognized as the successor
entity to the Trust and the consolidated financial statements would reflect
financial position, results of operations and cash flows as if the corporation
had always carried on the business formerly carried on by the Trust. Certain
terms such as shareholder, unitholder, dividend, and distribution would be
used interchangeably throughout the consolidated financial statements.
The corporation would expect to allocate its cash flow among funding a
portion of capital expenditures, periodic debt repayments, site reclamation
expenditures, and dividends, or distributions. 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 $2.1 billion of income tax pools, taxable income will
be reduced or potentially eliminated for the initial period post conversion.
The $2 billion of income tax pools (detailed in Table 19) 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 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
$16.68 per boe in the first quarter of 2009 from $15.92 per boe in 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 20:

Capital Expenditures and Net Acquisitions

Total capital expenditures, excluding acquisitions and dispositions,
totaled $97.2 million in the first quarter of 2009 compared to $111.3 million
in the same period of 2008. This amount was incurred on drilling and
completions, geological, geophysical and facilities expenditures.
During the first quarter of 2009, the Trust drilled 81 gross wells on
operated properties, 56 of which were completed in the quarter in addition to
six wells that were drilled in the fourth quarter of 2008.
In addition to capital expenditures on development activities, the Trust
completed net property acquisitions of $6.2 million in the first quarter of
2009 most of which related to the acquisition of undeveloped land in the
Dawson area.
For the remainder of 2009, the Trust expects to drill 41 gross wells on
operated properties, complete all wells in inventory and construct a
substantial portion of the Dawson gas plant that is now expected to be on
stream by the end of the first quarter of 2010. Total capital expenditures are
forecast to be $350 million in 2009.
A breakdown of capital expenditures and net acquisitions is shown in

Asset Retirement Obligation and Reclamation Fund

At March 31, 2009, the Trust recorded an Asset Retirement Obligation
("ARO") of $142.5 million ($141.5 million at December 31, 2008) for future
abandonment and reclamation of the Trust's properties.
Included in the March 31, 2009 ARO balance was a $0.4 million increase
related to development activities in the first three months of 2009, $2.3
million for accretion expense in the period and a reduction of $1.7 million
for actual abandonment expenditures incurred in the first quarter of 2009.
ARC's reclamations funds held $26.6 million as at March 31, 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.

Capitalization, Financial Resources and Liquidity

A breakdown of the Trust's capital structure is outlined in Table 23, as
at March 31, 2009 and December 31, 2008:

<<
Table 23
-------------------------------------------------------------------------

(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 March 31 and
December 31 including the total number of trust units issuable for
exchangeable shares at March 31 and December 31 multiplied by the
closing trust unit price of $14.15 and $20.10 at March 31, 2009 and
December 31, 2008, respectively.
(3) Total capitalization as presented does not have any standardized
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 March 31, 2009, the Trust's current credit facilities comprised US$212
million in senior secured notes currently outstanding, a Cdn$800 million
syndicated bank credit facility, of which $434.5 million was outstanding and a
Cdn$25 million demand working capital facility, of which $2.1 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 March 31, 2009; these agreements are available at
www.SEDAR.com. The major financial covenants are described below:

<<
- Long-term debt and letters of credit not to exceed three times
annualized net income before non-cash items and interest expense;

- Long-term debt, letters of credit, and subordinated debt not to
exceed four times annualized net income before non-cash items and
interest expense; and

- Long-term debt and letters of credit not to exceed 50 per cent of the
book value of unitholders' equity and long-term debt, letters of
credit, and subordinated debt.
>>

On April 14, 2009, the Trust announced the closing of a private placement
of long-term debt in the form of senior secured notes totaling US$125 million
at a blended average interest rate of 7.47 per cent. The notes were offered in
three tranches, one tranche of US$67.5 million senior notes with a five year
average life repayable in years 2012 through 2016 issued at an interest rate
of 7.19 per cent. The second tranche of US$35 million senior notes with a 10
year average life repayable in years 2017 through 2021, issued at an interest
rate of 8.21 per cent. The third tranche of Cdn$29 million senior notes was
issued with a five year average life repayable in years 2012 through 2016,
issued at an interest rate of 6.5 per cent.
In April 2009, ARC also extended its uncommitted master shelf agreement
from May 2009 to April 2012. The extended agreement allows for an aggregate
draw of up to US$225 million (Cdn$283.5 million) in long term notes at a rate
equal to the related U.S. treasuries corresponding to the term of the notes
plus an appropriate credit risk adjustment at the time of issuance.
As at the date of this MD&A, the Trust has approximately $610 million of
unused credit available: $445 million under its credit facility, and $165
million available to draw long term notes under the master shelf agreement.
As a result of the weakened global economic situation, the Trust along
with all other oil and gas entities will 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 2009 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 2009 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 March 31, 2009, there were 236 million trust units issued and issuable
for exchangeable shares, an increase of 16.8 million trust units from December
31, 2008.
On February 6, 2009, the Trust closed its previously announced equity
offering for 15 million trust units. The gross proceeds raised under this
offering were $253 million and proceeds net of underwriter and transaction
fees were approximately $240 million. The proceeds were used to reduce
outstanding indebtedness under the Trust's credit facility.
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 quarter of 2009, the Trust raised proceeds of
$18.7 million and issued 1.3 million trust units pursuant to the DRIP at an
average price of $14.75 per unit.

Distributions

ARC declared distributions of $82 million ($0.36 per unit), representing
66 per cent of 2009 first quarter cash flow from operating activities compared
to distributions of $126.8 million ($0.60 per unit) representing 60 per cent
of cash flow from operating activities in the first quarter of 2008.
As a result of the current commodity price environment, the monthly
distribution has decreased from $0.12 per unit to $0.10 per unit starting with
the distribution declared for the month of May and payable on June 15, 2009.
The decrease in distributions will provide the Trust with greater financial
flexibility to execute strategic capital projects while maintaining a
conservative debt balance and strong balance sheet.
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 quarter of 2009, the Trust
withheld 34 per cent of cash flow from operating activities to fund
45 per cent of the capital program excluding acquisitions. The
remaining portion of capital expenditures was financed by proceeds
from the DRIP program and debt.

- An annual contribution to the reclamation funds, with $12 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 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. Refer to the
"Capital Structure and Liquidity" section of this MD&A for a detailed
review of the debt covenants.

- 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 will decrease.

- 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. Presently, the Trust
estimates that $16.8 million to $56.9 million will be paid out
pursuant to such commitments in 2009 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.

Cash flow from operating activities and distributions in total and per
unit are summarized in Table 24:

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 quarter of 2009 the
Trust funded 45 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
monthly distribution amounts and distribution dates for 2009.

Environmental Initiatives Impacting the Trust

In March of 2009, ARC was selected to receive a portion of the required
funding for the next two phases of its Heartland Area Redwater Project
("HARP") from the ecoENERGY Technology Initiative of the Federal Government of
Canada. This project is designed to demonstrate the feasibility of safe CO(2)
storage in the Redwater Leduc Reef saline water formation, situated northeast
of Edmonton, Alberta. This site is located close to the Alberta Industrial
Heartland region, where there are a number of large industrial sources of
greenhouse gas ("GHG") emissions, including chemical and fertilizer plants and
several oil sands upgraders that are operating, being built or in the planning
stages.
The Redwater Leduc Reef is also strategically located along a
straight-line path between Fort McMurray and Edmonton, a potential route for a
CO(2) pipeline from Fort McMurray. Preliminary work estimates the total
storage capacity of the saline water formation portion of the reef to be one
gigatonne of CO(2).
Over the long term, this project will demonstrate the prospect of carbon
capture and storage on a commercial scale (several million tonnes per year),
contributing to a significant reduction in GHG emissions.

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 25.

>>

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 March 31, 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 a 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 $350 million. This commitment has not been
disclosed in the commitment table (Table 25) 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 $350 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 25.
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 25) 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 25) 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 25), 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 March 31,
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 March 31, 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 three months of
2009.

Financial Reporting Update

Current Year Accounting Changes

Effective January 1, 2009, the Trust prospectively 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.

Future Accounting Changes

International Financial Reporting Standards ("IFRS")

In April 2008, the CICA published the exposure draft "Adopting IFRSs in
Canada". The exposure draft proposes to incorporate IFRSs 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 IFRSs. The Trust is currently reviewing the
standards to determine the potential impact on its Consolidated Financial
Statements. The Trust has appointed internal staff to lead the conversion
project along with sponsorship from the senior leadership team. In addition,
an external advisor has been retained to assist the Trust in scoping its
conversion project. The Trust has performed a diagnostic analysis that
identifies differences between the Trust's current accounting policies and
IFRSs. The Trust has evaluated the impact of these differences and is
developing accounting policies in order to comply with IFRS.

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.

Forward-looking Information and Statements

This news release contains certain forward-looking information and
statements within the meaning of applicable securities laws. The use of any of
the words "expect", "anticipate", "continue", "estimate", "objective",
"ongoing", "may", "will", "project", "should", "believe", "plans", "intends",
"strategy" and similar expressions are intended to identify forward-looking
information or statements. In particular, but without limiting the foregoing,
this news release contains forward-looking information and statements
pertaining to the following: the volumes and estimated value of ARC's oil and
gas reserves; the life of ARC's reserves; the volume and product mix of ARC's
oil and gas production; future oil and natural gas prices and ARC's commodity
risk management programs; the amount of future asset retirement obligations;
future liquidity and financial capacity; future results from operations and
operating metrics; future costs, expenses and royalty rates; future interest
costs; future development, exploration, acquisition and development activities
(including drilling plans) and related capital expenditures, future tax
treatment of income trusts and future taxes payable by ARC; and ARC's tax
pools.
The forward-looking information and statements contained in this news
release reflect several material factors and expectations and assumptions of
ARC including, without limitation: that ARC will continue to conduct its
operations in a manner consistent with past operations; the general
continuance of current industry conditions; the continuance of existing (and
in certain circumstances, the implementation of proposed) tax, royalty and
regulatory regimes; the accuracy of the estimates of ARC's reserves and
resource volumes; certain commodity price and other cost assumptions; and the
continued availability of adequate debt and equity financing and cash flow to
fund its planned expenditures; ARC believes the material factors, expectations
and assumptions reflected in the forward-looking information and statements
are reasonable but no assurance can be given that these factors, expectations
and assumptions will prove to be correct.
The forward-looking information and statements included in this news
release are not guarantees of future performance and should not be unduly
relied upon. Such information and 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 information
or statements including, without limitation: changes in commodity prices;
changes in the demand for or supply of ARC's products; unanticipated operating
results or production declines; changes in tax or environmental laws, royalty
rates or other regulatory matters; changes in development plans of ARC or by
third party operators of ARC's properties, increased debt levels or debt
service requirements; inaccurate estimation of ARC's oil and gas reserve and
resource volumes; limited, unfavorable or a lack of access to capital markets;
increased costs; a lack of adequate insurance coverage; the impact of
competitors; and certain other risks detailed from time to time in ARC's
public disclosure documents (including, without limitation, those risks
identified in this news release and in ARC's Annual Information Form).
The forward-looking information and statements contained in this news
release speak only as of the date of this news release, and none of ARC or its
subsidiaries assumes any obligation to publicly update or revise them to
reflect new events or circumstances, except as may be required pursuant to
applicable laws.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
March 31, 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

International Financial Reporting Standards ("IFRS")

In April 2008, the CICA published the exposure draft "Adopting IFRSs
in Canada". The exposure draft proposes to incorporate IFRSs 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 IFRSs. The Trust
is currently reviewing the standards to determine the potential
impact on its Consolidated Financial Statements. The Trust has
appointed internal staff to lead the conversion project along with
sponsorship from the senior leadership team. In addition, an external
advisor has been retained to assist the Trust in scoping its
conversion project. The Trust has performed a diagnostic analysis
that identifies differences between the Trust's current accounting
policies and IFRSs. The Trust has evaluated the impact of these
differences and is developing accounting policies in order to comply
with IFRS.

3. CASH AND CASH EQUIVALENTS

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

4. FINANCIAL ASSETS AND CREDIT RISK

Credit risk is the risk of financial loss to the Trust if a partner
or counterparty to a product sales contract or financial instrument
fails to meet its contractual obligations. The Trust is exposed to
credit risk with respect to its cash equivalents, accounts
receivable, reclamation funds, and risk management contracts. Most of
the Trust's accounts receivable relate to oil and natural gas sales
and are subject to typical industry credit risks. The Trust manages
this credit risk as follows:

- By entering into sales contracts with only established credit
worthy counterparties as verified by a third party rating agency,
through internal evaluation or by requiring security such as
letters of credit;
- By limiting exposure to any one counterparty in accordance with
the Trust's Credit Policy;
- By restricting cash equivalent investments, reclamation fund
investments, and risk management transactions to counterparties
that, at the time of transaction are not less than investment
grade;

The majority of the credit exposure on accounts receivable at
March 31, 2009 pertains to accrued revenue for March 2009 production
volumes. The Trust transacts with a number of oil and natural gas
marketing companies and commodity end users ("commodity purchasers").
Commodity purchasers 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 March 31, 2009, no one counterparty accounted for more than
20 per cent of the total accounts receivable balance and the largest
commodity purchaser receivable balance is 50 per cent secured with
Letters of Credit.

During the first three months of 2009 the Trust did not record any
provision for non-collectible accounts receivable. The Trust's
allowance for doubtful accounts was $32 million as at March 31, 2009
and December 31, 2008.

When determining whether amounts that are past due are collectable,
management assesses the creditworthiness 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
March 31, 2009, $3.9 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. FINANCIAL LIABILITIES AND LIQUIDITY RISK

Liquidity risk is the risk that the Trust will not be able to meet
its financial obligations as they become due. The Trust actively
manages its liquidity through cash, distribution policy, and debt and
equity management strategies. Such strategies include continuously
monitoring forecasted and actual cash flows from operating, financing
and investing activities, available credit under existing banking
arrangements and opportunities to issue additional Trust units.
Management believes that future cash flows generated from these
sources will be adequate to settle the Trust's financial liabilities.

The following table details the Trust's financial liabilities as at
March 31, 2009:

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 (2.5 per cent at March 31, 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 anytime 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 depending on the ratio of
consolidated long-term debt and letters of credit to annualized net
income before non-cash items and interest expense. These stamping
fees vary between a minimum of 60 basis points ("bps") to a maximum
of 110 bps.

Debt Covenants

The following are the significant financial covenants governing the
revolving credit facilities:

- Long-term debt and letters of credit not to exceed three times
annualized net income before non-cash items and interest expense;
- Long-term debt, letters of credit, and subordinated debt not to
exceed four times annualized net income before non-cash items and
interest expense; and
- Long-term debt and letters of credit not to exceed 50 per cent of
the book value of unitholders' equity and long-term debt, letters
of credit, and subordinated debt.

In the event that the Trust enters into a material acquisition
whereby the purchase price exceeds 10 per cent of the book value of
the Trust's assets, the ratios in the first two covenants above are
increased to 3.5 and 5.5 times respectively, while the third covenant
is increased to 55 per cent for the subsequent six month period. As
at March 31, 2009, the Trust had $1.9 million in letters of credit
($1.9 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.

During the first quarter of 2009, the weighted-average effective
interest rate under the credit facility was 1.7 per cent
(3.8 per cent in 2008).

Amounts of US$16.4 million due under the senior notes and
$2.1 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. The fair value of senior
secured notes as at March 31, 2009 is $297.8 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.

Interest paid during the first quarter of 2009 was $1.4 million less
than interest expense ($0.8 million less than interest expense in the
first quarter of 2008).

On April 14, 2009, the Trust closed a private placement of long-term
debt in the form of senior secured notes totaling US$125 million at a
blended average interest rate of 7.47 per cent. The notes were
offered in three tranches, one tranche of US$67.5 million senior
notes with a five year average life repayable in years 2012 through
2016 issued at an interest rate of 7.19 per cent. The second tranche
of US$35 million senior notes with a 10 year average life repayable
in years 2017 through 2021, issued at an interest rate of 8.21 per
cent. The third tranche of Cdn$29 million senior notes was issued
with a five year average life repayable in years 2012 through 2016
and at an interest rate of 6.5 per cent.

In April 2009, ARC extended its uncommitted master shelf agreement
from May 2009 to April 2012. The extended agreement allows for an
aggregate draw of up to US$225 million (Cdn$283.5 million) in long
term notes at a rate equal to the related U.S. treasuries
corresponding to the term of the notes plus an appropriate credit
risk adjustment at the time of issuance. As at March 31, 2009, the
Trust has drawn US$87 million (Cdn$ 109.6 million) under this
agreement. These amounts are reflected in the above table.

The Trust's 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.

7. ASSET RETIREMENT OBLIGATIONS

The following table reconciles the Trust's asset retirement
obligations:

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

Accretion expense 2.3 9.3
---------------------------------------------------------------------
Balance, end of period $ 142.5 $ 141.5
---------------------------------------------------------------------
---------------------------------------------------------------------

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

8. CAPITAL MANAGEMENT

The Trust's objective when managing its capital is to maintain a
conservative capital structure which 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
March 31, 2009 the Trust's net debt to annualized cash flow from
operating activities ratio is 1.6 and its net debt to total
capitalization ratio is 19 per cent.

---------------------------------------------------------------------
---------------------------------------------------------------------
(1) Market capitalization, net debt obligations and total
capitalization 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.

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 March 31, 2009
the Trust is in compliance with all covenants. Refer to Note 6 for
further details.

9. MARKET RISK MANAGEMENT

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 March 31, 2009 that do not qualify for hedge accounting:

At March 31, 2009, the fair value of the contracts that were not
designated as accounting hedges was a loss of $3.2 million. The Trust
recorded a gain on risk management contracts of $9.7 million in the
statement of income for the period ended March 31, 2009
($48.2 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 $5.9 million at
March 31, 2009 ($57.5 million loss at March 31, 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 cost of
$13.6 million. These contracts were originally designated as
effective accounting hedges on their respective contract dates and
hedge accounting was applied. During 2008, the $13.6 million loss was
reclassified from Other Comprehensive Income ("OCI"), net of tax 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 gain of $0.1 million
for the three months ended March 31, 2009 (gain of $0.5 million in
2008) has been included in operating costs on these electricity
contracts. The unrealized fair value gain of $0.3 million on these
contracts has been recorded on the Consolidated Balance Sheet at
March 31, 2009 with the movement in fair value recorded in OCI, net
of tax. The fair value movement for the period ended March 31, 2009
is an unrealized loss of $3.0 million. As at March 31, 2009
$0.2 million of the unrealized fair value gain 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:

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

---------------------------------------------------------------------
Fair value, end of period(1) $ 0.3 $ 5.8
---------------------------------------------------------------------
---------------------------------------------------------------------
(1) Intrinsic value of risk management contracts designated as
effective accounting hedges equals a gain of $0.3 million at
March 31, 2009 ($5.7 million gain at March 31, 2008).

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 March 31, 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.

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.

(1) Distributions include accrued and non-cash amounts of
$13.8 million for the period ended March 31, 2009 ($26 million
for the period ended March 31, 2008).
(2) Distributions per trust unit reflect the sum of the per trust
unit amounts declared monthly to unitholders.

14. 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) expense of
$(10.8) million and $(1.3) million to general and administrative and
operating expenses, respectively, and capitalized $(2.2) million to
property, plant and equipment in the three months ended March 31,
2009 for the estimated change in the Plan liability ($11.9 million,
$1.9 million, and $2.0 million as expense for the three months ended
March 31, 2008). The non-cash compensation recovery was based on the
March 31, 2009 unit price of $14.15 ($26.38 at March 31, 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 three
months ended March 31, 2009:

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

(1) Includes $0.3 million of recoverable amounts recorded in accounts
receivable as at March 31, 2009 ($1.1 million for 2008).

During the first three months of 2009 cash payments of $7.8 million
were made to employees relating to the Whole Unit Plan compared to
$18.5 million paid in April of 2008. In October 2008, vesting periods
were revised from April and October to March and September of each
year commencing in 2009.

(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 2010.
(5) Fixed premiums to be paid in future periods on certain commodity
risk management contracts.

In addition to the above Risk management contract premiums, the Trust
has commitments related to its risk management program (see Note 9).

The Trust enters into commitments for capital expenditures in advance
of the expenditures being made. At a 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 expenditures in a future
period. The Trust's 2009 capital budget has been set at $350 million.
This commitment has not been disclosed in the commitment table 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 $350 million includes approximately
$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 amounts to be incurred in 2010. The
operating lease commitments for the new space are included in the
table above.

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 above
table does not include any commitments for outstanding litigation and
claims.
