Canadian Oil Sands Trust Raises Quarterly Distribution to $1.25 Per Trust Unit

CALGARY, ALBERTA--(Marketwire - July 29, 2008) -

All financial figures are unaudited and in Canadian dollars unless otherwise noted.

Canadian Oil Sands Trust (TSX:COS.UN) ("Canadian Oil Sands", the "Trust" or "we") today announced that cash from operating activities in the second quarter of 2008 increased 27 per cent to $413 million ($0.86 per Trust unit ("Unit")), over the same 2007 period. Year-to-date, cash from operating activities was up 62 per cent to $854 million ($1.78 per Unit) compared with the 2007 six-month period. The increase in cash from operating activities on both a quarter and year-to-date basis reflects a higher realized selling price for our synthetic crude oil partially offset by lower sales volumes and higher operating and Crown royalties expenses.

Net income for the second quarter 2008 was $497 million ($1.04 per Unit) compared with a net loss of $395 million ($0.82 per Unit) for the 2007 period. Year-to-date, net income totaled $795 million ($1.66 per Unit) in 2008 compared with a net loss of $133 million ($0.28 per Unit) for 2007. In the second quarter of 2007 the Trust recorded a one time future income tax expense of $701 million for the substantive enactment of trust taxation legislation, resulting in net losses for the 2007 second quarter and year-to-date periods.

The Trust has declared a 25 per cent increase in the quarterly distribution amount to $1.25 per Unit from $1.00 per Unit for Unitholders of record on August 15, 2008, payable on August 29, 2008.

Sales volumes quarter-over-quarter and on a year-to-date basis were lower in 2008 compared with 2007. In 2008, sales volumes averaged about 97,700 barrels per day and 98,500 barrels per day during the second quarter and first half of the year, respectively. Second quarter 2008 sales volumes were primarily impacted by a scheduled coker turnaround while the first quarter was marked by a disruption in operations and reliability challenges in bitumen production and extraction.

Operating costs in the second quarter of 2008 rose 39 per cent to $41.92 per barrel from the comparative 2007 quarter. For the first half 2008, operating costs were $38.90 per barrel, up 46 per cent from the same period last year. The increase primarily reflects operational difficulties during the first half of the year, higher bitumen production costs with more mining activity, and the purchase of third-party bitumen to support the expanded capacity of the upgrader. As well, purchased energy costs rose with higher natural gas consumption and prices in 2008.

"As we entered the third quarter of 2008, operational reliability has improved with Syncrude achieving near design capacity rates in June and July. While the third quarter will also be impacted by a scheduled coker turnaround, confidence in Syncrude's operations for the remainder of the year and buoyant crude oil prices encourage us to once again increase our quarterly distribution," said Marcel Coutu, President and Chief Executive Officer. "A principle tenet of our financial plan is to provide investors with a fuller payout of the cash generated by our business during periods of lower capital investment in order to manage an efficient capital structure for the Trust."

In the second quarter of 2008, Syncrude's total recordable injury rate was 0.59 for every 200,000 hours worked compared to a rate of 0.70 recorded for the same period of 2007.

2008 Outlook

The Trust is estimating Syncrude production to be 106 million barrels in 2008 with a range of 103 to 109 million barrels (net to the Trust, equivalent to 39 million barrels with a range of 38 to 40 million barrels). This production estimate was slightly reduced from the one provided on April 28, 2008, to reflect actual production volumes in the first half of the year. The Trust has increased its average annual operating cost estimate for 2008 to $35.46 per barrel. Cash from operating activities is estimated to be $4.90 per Unit, based on an average WTI price of US$120 per barrel in 2008.

More information on the Trust's Outlook is provided in the MD&A section of this report and the July 29, 2008 guidance document, which is available on the Trust's web site at www.cos-trust.com under "investor information".

Mining Association of Canada awards Syncrude for 2007 sustainability

performance

Syncrude received five 2007 performance awards from the Mining Association of Canada ("MAC") under its Towards Sustainable Mining ("TSM") initiative. TSM is a benchmarking program that assesses company performance in the areas of Tailings Management, Energy and Greenhouse Gas ("GHG") Management, Crisis Management, and External Outreach. Syncrude has participated in this program since inception and had its results externally verified in both 2006 and 2007. Syncrude received two awards for attaining the highest level of performance in Crisis Management and External Outreach and two for meeting MAC's established benchmark standard in Tailings Management and Energy/GHG Management. Syncrude was also presented with a special award for being the first MAC member to meet the established benchmark in all categories.

Canada's oil sands: a different conversation

Canada's oil sands producers and developers have joined together to engage Canadians and other interested individuals in an open discussion about oil sands development, and to foster a collaborative process that will create better understanding and solutions to the related environmental and social issues.

A central component of this "different conversation" is a new website (www.canadasoilsands.ca) that features a public discussion forum through which Canadians and other interested parties can express their views regarding oil sands development. Over time, producers intend to engage with interested parties directly through the site, responding to issues and proposing solutions.

MANAGEMENT'S DISCUSSION AND ANALYSIS

The following Management's Discussion and Analysis ("MD&A") was prepared as of July 29, 2008 and should be read in conjunction with the unaudited interim consolidated financial statements of Canadian Oil Sands Trust ("Canadian Oil Sands" or the "Trust") for the six months ended June 30, 2008 and June 30, 2007, and the audited consolidated financial statements and MD&A of the Trust for the year ended December 31, 2007 and the Trust's Annual Information Form ("AIF") dated March 15, 2008.

REVIEW OF SYNCRUDE OPERATIONS

During the second quarter of 2008, crude oil production from the Syncrude Joint Venture ("Syncrude") totalled 24.1 million barrels, or about 265,000 barrels per day, compared with 23.9 million barrels, or about 263,000 barrels per day, during the same period of 2007. Net to the Trust, production totalled 8.9 million barrels in the second quarter of 2008 based on our 36.74 per cent working interest compared with 8.8 million barrels in 2007.

Production in the second quarter of 2008 was primarily impacted by a scheduled 45-day turnaround on Coker 8-1, which began in April and was completed in mid-May. Operational problems with two sulphur plants and an extended hydrogen plant turnaround also constrained production in the quarter. These issues were resolved in May, leading to strong performance for June with volumes averaging about 361,000 barrels per day. In the second quarter of 2007, production was primarily impacted by maintenance on Coker 8-3 and a planned turnaround of the LC-Finer.

Year-to-date, Syncrude produced 48.4 million barrels in 2008 or about 266,000 barrels per day, compared with 50.5 million barrels or about 279,000 barrels per day in 2007. In addition to the coker turnaround during the second quarter, first half 2008 production was impacted by a disruption in operations triggered by extremely cold weather during the first quarter. The cold weather also affected bitumen production and extraction. By comparison, production in the first half of 2007 was impacted by maintenance on Coker 8-3, Coker 8-2 and other units.

Operating costs increased to $41.92 per barrel in the second quarter of 2008, up $11.79 per barrel from the same quarter last year. Year-to-date operating costs were $38.90 per barrel in 2008 versus $26.70 per barrel in 2007 (see the "Operating costs" section of this MD&A for further discussion).

Syncrude's facilities have the design capability to produce approximately 375,000 barrels per day when operating at full capacity under optimal conditions and with no downtime for maintenance or turnarounds. Under normal operating conditions, scheduled downtime is required for maintenance and turnaround activities and unscheduled downtime will occur as a result of operational and mechanical problems, unanticipated repairs and other slowdowns. When allowances for such downtime are included, the daily design productive capacity of Syncrude's facilities is approximately 350,000 barrels per day on average and is referred to as "barrels per calendar day". All references to Syncrude's productive capacity in this report refer to barrels per calendar day, unless stated otherwise.

The Trust's production volumes differ from its sales volumes due to changes in inventory, which are primarily in-transit pipeline volumes that vary with current production. The impact of Syncrude's 2008 operations on Canadian Oil Sands' financial results is more fully discussed later in this MD&A.

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


During the last eight quarters, the following items have had a significant impact on the Trust's financial results:

- U.S. dollar West Texas Intermediate ("WTI") oil prices, which impact

the Trust's revenues, have increased significantly over the last six

quarters, reaching a high of approximately US$140 per barrel during

the second quarter of 2008.

- The substantive enactment of income tax legislation in June 2007 to

apply a new tax on distributions from Canadian public trusts starting

in 2011 resulted in an additional future income tax expense of

$701 million in the second quarter of 2007. Other corporate tax rate

reductions substantively enacted in the fourth and second quarters of

2007 resulted in future income tax recoveries of $153 million and

$38 million in each quarter, respectively.

- Syncrude's Stage 3 expansion came on-line at the end of August 2006,

increasing Syncrude's productive design capacity by approximately

100,000 barrels per day with a corresponding pro-rata increase to the

Trust's sales volumes, revenues, operating costs, and depletion,

depreciation and accretion ("DD&A") expense.

- On January 2, 2007 the Trust acquired a 1.25 per cent working

interest in Syncrude from Talisman Energy Inc. Commencing in 2007,

the Trust's financial results reflect a 36.74 per cent working

interest in Syncrude while the 2006 financial results reflect the

Trust's previous ownership of 35.49 per cent.

- U.S. to Canadian dollar exchange rate fluctuations have impacted

commodity pricing and have resulted in significant unrealized foreign

exchange gains and losses on the revaluation of U.S. dollar

denominated debt.

Quarterly variances in revenues, net income, and cash from operating activities are caused by fluctuations in crude oil prices, production and sales volumes, operating costs and natural gas prices. Net income also is impacted by foreign exchange gains and losses and by future income tax amounts. A large proportion of operating costs are fixed and, as such, per barrel operating costs are highly variable to production volumes. While the supply/demand balance for crude oil affects selling prices, the impact of this equation is difficult to predict and quantify and has not displayed significant seasonality. Maintenance and turnaround activities are typically scheduled to avoid the winter months; however, the exact timing of unit shutdowns cannot be precisely scheduled, and unplanned outages may occur. Accordingly, production levels may not display reliable seasonality patterns or trends. Maintenance and turnaround costs are expensed in the period incurred and can lead to significant increases in operating costs and reductions in production in those periods. Natural gas prices are typically higher in winter months as heating demand rises, but this seasonality is significantly influenced by weather conditions and North American natural gas inventory levels.

REVIEW OF FINANCIAL RESULTS

In the second quarter of 2008, net income amounted to $497 million, or $1.04 per Trust unit ("Unit"), compared with a net loss of $395 million, or $0.82 per Unit, recorded in the comparable quarter in 2007. The loss in the second quarter of 2007 was primarily the result of a one time $701 million future income tax expense recorded on the substantive enactment of trust taxation legislation. In the second quarter of 2008, revenues net of crude oil purchases and transportation expense totalled approximately $1.2 billion, an increase of approximately $490 million relative to the second quarter of 2007 as a result of higher crude oil prices. Operating costs increased from $271 million in the second quarter of 2007 to $373 million in the second quarter of 2008 as a result of increased contractor and employee costs, additional mining material moved in the quarter, increased energy costs and bitumen purchases. Operating costs in both the second quarters of 2008 and 2007 reflect coker maintenance and turnarounds.

Year-to-date net income totaled $795 million, or $1.66 per Unit in 2008 compared with a net loss of $133 million, or $0.28 per Unit, recorded in 2007. The improvement in net income primarily was the result of higher revenues net of higher operating costs and Crown royalties in 2008 without the impact of the one time future income tax expense of $701 million that was recorded in 2007.

Cash from operating activities increased to $413 million for the second quarter of 2008 versus $324 million for the second quarter of 2007. Year-to-date cash from operating activities increased to $854 million for 2008 versus $526 million for 2007. The increase in cash from operating activities was the result of the higher revenues net of increases in operating expenses, Crown royalties and changes in non-cash working capital.

Changes in non-cash working capital decreased cash from operating activities by $162 million in the second quarter of 2008, primarily as a result of higher accounts receivable at June 30, 2008 from stronger sales volumes and pricing in the month of June 2008 versus March 2008. In the second quarter of 2007, changes in non-cash working capital increased cash from operating activities by $57 million, primarily as a result of lower accounts receivable at June 30, 2007 relative to March 31, 2007.

Year-to-date changes in non-cash working capital decreased cash from operating activities by $136 million in 2008, primarily as a result of higher accounts receivable net of higher accounts payable at June 30, 2008 relative to December 31, 2007. In the same period of 2007, changes in non-cash working capital decreased cash from operating activities by $37 million primarily as a result of higher accounts receivable and lower accounts payable at June 30, 2007 relative to December 31, 2007.

Non-cash working capital and changes therein can vary on a period-by-period basis as a result of the timing and settlements of accounts receivable and accounts payable balances, and are impacted by a number of factors including changes in revenue, operating expenses, Crown royalties, the timing of capital expenditures, and inventory fluctuations.

(3) SCO sales revenue after crude oil purchases and transportation

expense divided by sales volumes, net of purchased crude oil volumes.


The increase in sales revenue for 2008 versus 2007 on a quarterly and on a year-to-date basis was due to a higher realized selling price for our synthetic crude oil ("SCO") offset by a slight decline in sales volumes.

The increase in the SCO selling price primarily reflects the increase in WTI prices in 2008. During the second quarter of 2008, WTI prices averaged US$123.80 per barrel compared to US$65.02 per barrel for the second quarter of 2007. Year-to-date, WTI prices averaged US$111.12 per barrel in 2008 versus US$61.68 per barrel in 2007. The increase in US dollar WTI prices was tempered by a stronger Canadian dollar, which averaged $0.99 US/Cdn year-to-date in 2008 compared with $0.88 US/Cdn in 2007, and averaged $0.99 US/Cdn for the second quarter of 2008 compared with $0.91 US/Cdn for the second quarter of 2007.

In addition to the increase in WTI prices, our SCO continued to receive a premium to Canadian dollar WTI (the "differential") in 2008. In the second quarter of 2008, the Trust's SCO realized a weighted-average premium of $4.05 per barrel compared with the average Canadian dollar WTI price versus a premium of $4.85 per barrel in the same period in 2007. Year-to-date in 2008, the Trust's SCO realized a weighted-average premium of $2.87 per barrel relative to the average Canadian dollar WTI price versus a premium of $2.28 per barrel for 2007. We believe that the modest improvement in the differential in 2008 on a year-to-date basis was due to a tighter supply/demand balance for SCO.

The Trust's sales volumes for the second quarter of 2008 averaged about 97,700 barrels per day versus an average of about 98,700 barrels per day in the second quarter of 2007. Year-to-date sales volumes averaged about 98,500 barrels per day in 2008 versus an average of about 103,800 barrels per day for 2007. Sales volumes for 2008 were impacted by the scheduled turnaround of Coker 8-1 during the second quarter and by operational difficulties during the first quarter. Sales volumes in 2007 were impacted by maintenance on Coker 8-3, Coker 8-2 and other units.

In the second quarter of 2008, operating costs were $373 million, averaging $41.92 per barrel, an increase of $102 million, or $11.79 per barrel, over the second quarter of 2007 operating costs of $271 million. Operating costs in both the second quarters of 2008 and 2007 reflect coker maintenance and turnarounds. Year-to-date operating costs were $697 million in 2008, averaging $38.90 per barrel, an increase of $195 million, or $12.20 per barrel over 2007. The increase in costs for the reported periods is primarily due to the following:

- Additional overburden material was moved during the first and

second quarters of 2008 versus 2007. Syncrude also increased its use

of contracted equipment and operators to supplement its own material

movement activities in 2008 in order to re-establish exposed mineable

ore inventory and meet operational requirements;

- increased costs for contractors and wages for Syncrude staff on a

quarterly and on a year-to-date basis as a result of inflationary

pressures and contract settlements;

- the purchase of incremental bitumen in 2008 to support production

during times of internal bitumen supply shortfalls;

- inflationary pressure for materials and consumables;

- additional costs during the first quarter of 2008 associated with

resuming shipments at Syncrude following the disruption of operations

early in the year;

- higher energy costs reflecting higher natural gas prices and

increased natural gas consumption on per barrel basis due to

operational inefficiencies during 2008; and

- an increase in the value of Syncrude's long term incentive plan in

2008 versus 2007. A portion of Syncrude's long-term incentive plans

is based on the market return performance of several Syncrude owners'

shares and units, the market performance of which was stronger in the

first half of 2008 relative to the same period in 2007.

Operating costs per barrel also have increased in 2008 on a year-to-date basis as a result of reduced production volumes in 2008 versus 2007. A significant portion of Syncrude's operating costs are fixed and as such, any change in production impacts per unit operating costs. While inflationary pressures are expected to persist, improvements in operational reliability should help to reduce the costs related to the operational inefficiencies experienced during 2008.

Non-Production Costs

Non-production costs totalled $16 million and $15 million in the second quarters of 2008 and 2007, respectively. Year-to-date non-production costs totalled $33 million for both 2008 and 2007. Non-production costs consist primarily of development expenditures relating to capital programs, which are expensed, such as: commissioning costs, pre-feasibility engineering, technical and support services, research and development, and regulatory and stakeholder consultation expenditures. Non-production costs can vary on a periodic basis depending on the number of projects underway and the status of the projects.

Crown Royalties

In the second quarter of 2008, Crown royalties increased to $178 million, or $19.94 per barrel, from $89 million, or $9.94 per barrel, in the comparable 2007 quarter. Year-to-date Crown royalties increased to $309 million, or $17.24 per barrel, in 2008 from $183 million, or $9.75 per barrel in 2007. The increase in royalties in 2008 on both a quarterly and a year-to-date basis was primarily due to significantly increased revenues partially offset by higher operating costs.

Potential changes to Crown royalty terms by the Alberta government are discussed later in this MD&A.

The increase in depreciation and depletion ("D&D") expense in 2008 on a quarterly and on a year-to-date basis versus 2007 was due to a higher per barrel D&D rate. In 2008 the D&D rate per barrel of production increased to $11.07 from $8.31 in 2007 as a result of higher projected capital cost estimates for Syncrude in the Trust's December 31, 2007 independent reserves report.

Unrealized foreign exchange ("FX") gains and losses are the result of revaluations of our U.S. dollar denominated long-term debt caused by fluctuations in U.S. and Canadian dollar exchange rates. The unrealized FX gains and losses reported in 2008 resulted from the change in the value of the Canadian dollar relative to the U.S. dollar to $0.98 US/Cdn at June 30, 2008 from $0.97 US/Cdn at March 31, 2008 and $1.01 US/Cdn at December 31, 2007. The unrealized FX gains in 2007 were due to the change in the value of the Canadian dollar relative to the U.S. dollar to $0.94 US/Cdn at June 30, 2007 from $0.87 US/Cdn at March 31, 2008 and $0.86 US/Cdn at December 31, 2007.

Future Income Tax and Other

In the second quarter of 2008, a $10 million future income tax recovery was recorded on the reduction of temporary differences versus a future income tax expense of $665 million in the second quarter of 2007. On a year-to-date basis, a future income tax recovery of $24 million was recorded in 2008 on the reduction of temporary differences compared with a future income tax expense of $628 million in 2007.

Prior to the substantive enactment of Bill C-52 in June 2007, the federal government's legislation to tax distributions from income trusts commencing in 2011, Canadian Oil Sands' future income taxes reflected only those temporary differences in the Trust's subsidiaries. Upon the substantive enactment of Bill C-52, Canadian Oil Sands recorded a one-time $701 million future income tax expense and a corresponding future income tax liability related to the differences between the accounting and tax basis of the Trust's assets and liabilities.

In June 2008, Bill C-50, which contains legislation to adjust the deemed provincial component on the tax rate on distributions from income and royalty trusts expected to apply to Canadian Oil Sands commencing in 2011, passed third reading in the House of Commons. Under this legislation, we expect the provincial component of the tax applicable to Canadian Oil Sands will be reduced from 13 per cent to 10 per cent as substantially all of Canadian Oil Sands' activities are in Alberta. For accounting purposes, however, the adjustment to the provincial component of the tax is not considered substantively enacted as the income tax regulations for the adjustment have not been finalized. If the proposal becomes enacted, we expect to record a future income tax recovery based on the temporary differences at that time.

With the taxation of income trusts commencing January 1, 2011 Canadian Oil Sands is evaluating alternatives as to the best structure for its Unitholders in the future. On July 14, 2008, the Department of Finance released proposed conversion rules for income and royalty trusts. The draft rules, which are subject to comments by interested parties by September 15, 2008, are designed to permit income and royalty trusts to convert into public corporations and wind up without triggering adverse tax consequences to the income or royalty trust and its Unitholders. We are assessing the draft rules and their implications to the Trust. However, until the draft legislation is finalized and ultimately passed into law, we will not be able to complete our evaluation. Subject to the finalization of the conversion rules, we plan to retain the flow-through advantages of a trust structure until 2011 unless circumstances arise that favour a faster transition to an alternate structure. Canadian Oil Sands continues to be a long-term value investment in the oil sands and does not rely on the tax efficiency of a flow-through trust model to sustain its business. Our long-life reserves and non-declining production profile provide a solid foundation to generate future cash from operating activities.

CHANGES IN ACCOUNTING POLICIES

In its audited consolidated financial statements for the year ended December 31, 2007 ("Audited 2007 Financial Statements"), Canadian Oil Sands adopted the requirements of the Canadian Institute of Chartered Accountants ("CICA") Section 3862 Financial Instruments - Disclosures, Section 3863 Financial Instruments - Presentation and Section 1535 - Capital Disclosures. These standards were effective January 1, 2008, however, early adoption was encouraged by the CICA. Additional disclosures required as a result of adopting the standards can be found in the Trust's Audited 2007 Financial Statements.

In June 2007, the CICA issued a new accounting standard Section 3031 Inventories, which replaces the existing standard for inventories, Section 3030. The main features of the new section are as follows:

- measurement of inventories at the lower of cost and net realizable

value;

- consistent use of either first-in, first-out or a weighted average

cost formula to measure cost; and

- reversal of previous write-downs to net realizable value when there

is a subsequent increase to the value of inventories.

The new inventory standard is effective for the Trust beginning January 1, 2008. Application of the new standard did not have an impact on the Trust's financial statements.

NEW ACCOUNTING PRONOUNCEMENTS

In February 2008, the CICA issued a new accounting standard, Section 3064 - Goodwill and Intangible Assets, which replaces Section 3062 - Goodwill and Other Intangible Assets, and Section 3450 - Research and Development costs. The new section establishes standards for the recognition, measurement and disclosure of goodwill and intangible assets. The section is effective for the Trust beginning January 1, 2009. Application of the new section is not expected to have a material impact on the Trust's financial statements.

On February 13, 2008 the CICA Accounting Standards Board announced that Canadian public reporting issuers will be required to report under International Financial Reporting Standards ("IFRS") starting in 2011. Canadian Oil Sands has commenced assessing the impact on our business of adopting IFRS in 2011 and is preparing for the transition accordingly.

In the second quarter of 2008, Unitholder distributions exceeded cash from operating activities by $68 million as a result of changes in non-cash working capital. During the quarter, changes in non-cash working capital reduced cash from operating activities by $162 million, primarily as a result of a $198 million increase in accounts receivable at June 30, 2008 relative to March 31, 2008. For the second quarter of 2008, cash from operating activities along with opening cash balances at April 1, 2008 funded the Trust's distributions, capital expenditures, and reclamation trust fund contributions.

Year-to-date cash from operating activities exceeded Unitholder distributions by $13 million and, along with opening cash balances at January 1, 2008, funded the Trust's distributions, capital expenditures, and reclamation trust fund contributions.

Total distributions during 2008 exceeded net income on a year-to-date basis primarily as a result of DD&A. DD&A is a non-cash item that does not affect the Trust's cash from operating activities, balance sheet strength or ability to pay distributions over the next several years.

The Trust uses debt and equity financing to the extent that cash from operating activities is insufficient to fund distributions, capital expenditures, reclamation trust contributions, acquisitions and working capital changes from financing and investing activities.

On July 29, 2008 the Trust declared a quarterly distribution of $1.25 per Unit in respect of the third quarter of 2008 for a total distribution of $602 million. The distribution will be paid on August 29, 2008 to Unit holders of record on August 15, 2008. Quarterly distributions are approved by our Board of Directors after considering the current and expected economic conditions, ensuring financing capacity for Canadian Oil Sands' capital requirements, and with the objective of maintaining an investment grade credit rating.

The 25 per cent increase in the distribution over the previous quarter reflects the Trust's financial plan of managing its capital structure in anticipation of trust taxation in 2011. The Trust is distributing a fuller amount of cash from operating activities unless capital investment or acquisition opportunities arise that management believes offer Unitholders enhanced value. Additionally, under current market conditions, the Trust plans on raising its long-term net debt to about $1.6 billion by the end of 2010. We believe this net debt target reflects efficient capital management and will help conserve tax pools prior to trust taxation. The target is based on Syncrude's existing productive capacity and we will reconsider this target in light of Canadian Oil Sands future capital requirement plans.

In determining the Trust's distributions, Canadian Oil Sands considers funding for its significant operating obligations, which are included in cash from operating activities. Such obligations include the Trust's share of Syncrude's pension and reclamation funding, which amounted to $20 million and $18 million on a year-to-date basis in 2008 and 2007, respectively, and approximated the related expense for both pension and reclamation of $25 million and $22 million for each of the periods, respectively. While our share of Syncrude's annual pension funding has increased modestly as a result of the most recent actuarial valuation and our share of Syncrude's future reclamation costs has increased, we currently do not anticipate any material increases in funding related to these items for the next few years.

Debt covenants do not specifically limit the Trust's ability to pay distributions and are not expected to influence the Trust's liquidity in the foreseeable future. Aside from covenants relating to restrictions on Canadian Oil Sands' ability to sell all or substantially all of its assets or to change the nature of its business, the most restrictive financial covenant limits total debt-to-book capitalization at an amount less than 55 per cent. With a current net debt-to-book capitalization of approximately 20 per cent, a significant increase in debt or decrease in equity would be required to restrict the Trust's financial flexibility.

Cash from operating activities and net income can fluctuate dramatically from period to period reflecting, among other things, variability in operational performance, WTI prices, SCO differentials to WTI and FX rates. The Trust strives to smooth out the effect of this variability on distributions by taking a longer-term view of our outlook for our operating and business environment, our net debt level relative to our target, and our capital expenditure and other commitments. In that regard, we may distribute more or less in a period than we generate in cash from operating activities or net income. Nonetheless, the highly variable nature of our cash from operating activities introduces risk in our ability to sustain or provide stability in distributions and any expectations regarding the stability or sustainability of distributions are unwarranted and should not be implied.

As the Trust executes its financial plan, investors should anticipate increased variability in distributions and understand that current distribution levels may not be sustainable once we have reached our net debt target. As distributions comprise a larger percentage of cash from operating activities, the distributions will necessarily be more reflective of business performance and crude oil prices. Further, the taxation of income trusts commencing January 1, 2011 likely will materially alter our cash from operating activities, and consequently distribution levels.

As at June 30, 2008 the Trust had $840 million of credit facilities available and unutilized. In addition, the Trust had $67 million in letters of credit issued against a separate line of credit.

During the second quarter of 2008, the Trust repaid $150 million of medium term notes that matured.

Canadian Oil Sands has set a long-term net debt target of approximately $1.6 billion by the end of 2010. The Trust's actual net debt will fluctuate, however, as factors such as actual crude oil prices, Syncrude's operational performance, distributions, and FX rates vary from our assumptions.

CAPITAL EXPENDITURES

With the completion of Syncrude's Stage 3 project in 2006, Canadian Oil Sands' expansion capital expenditures have declined and capital costs for 2008 and 2007 are primarily related to sustaining capital. The Trust defines expansion capital expenditures as the costs incurred to grow the productive capacity of the operation, such as the Stage 3 project, while sustaining capital is effectively all other capital. Sustaining capital expenditures may fluctuate considerably year-to-year due to the timing of equipment replacement and other factors. The productive capacity of Syncrude's operations was previously described in the "Review of Syncrude Operations" section of this MD&A.

In the second quarter of 2008, capital expenditures totalled $54 million, compared with expenditures of $50 million in the same quarter of 2007. The Syncrude Emissions Reduction ("SER") project accounted for $21 million and $19 million of the capital spent in the second quarters of 2008 and 2007, respectively. The remaining amounts in each quarter pertained to other sustaining capital activities. Sustaining capital expenditures on a per barrel basis were approximately $6.00 and $5.35 in each of the second quarters of 2008 and 2007, respectively.

Year-to-date capital expenditures totalled $101 million in 2008 versus $83 million in 2007. The SER project accounted for $38 million and $34 million of the capital spent in 2008 and 2007, respectively, with the remaining expenditures relating to other sustaining capital activities. Sustaining capital expenditures on a per barrel basis were approximately $5.63 and $4.40 on a year-to-date basis in 2008 and 2007, respectively.

Syncrude is undertaking the SER project to retrofit technology into the operation of Syncrude's original two cokers to significantly reduce total sulphur dioxide and other emissions. While expenditures on the SER project are estimated at approximately $772 million ($284 million net to the Trust based on its 36.74 per cent working interest) there is upward cost pressure on the project. Syncrude is currently performing a full review of the SER project and will provide updates to cost estimates and timing after such review has been completed. The Trust's share of the SER project expenditures incurred to date is approximately $144 million, with the remaining costs expected to be incurred in the next three years to coordinate with equipment turnaround schedules.

Sustaining capital expenditures, including the SER project, are estimated to average approximately $8 per barrel for 2008. Over the longer term, we expect sustaining capital expenditures to average approximately $5 per barrel before inflation; however, over the next few years we expect to incur an additional $2 to $5 per barrel annually for large environmental and infrastructure projects. These projects include the relocation of certain mining trains and tailings systems, which are required as mining operations progress across the active leases. Tailings system projects also include initiatives to improve and supplement the effectiveness of systems used to separate water from sand and clay so that the water can be recycled back to the operation and solids can be incorporated into the final reclamation landscapes. Our per barrel estimates are based on estimated annual Syncrude production, which increases from 106 million barrels in 2008, or 39 million barrels net to the Trust, to 129 million barrels, or 47 million barrels net to the Trust, at design capacity.

Syncrude's next significant growth stage is anticipated to be the Stage 3 debottleneck, which is estimated to increase Syncrude's productive capacity by about 50,000 barrels per day. Following the debottleneck, the Stage 4 expansion was expected to grow Syncrude capacity by a further 100,000 barrels per day, post-2016. Syncrude is re-evaluating its plans to increase production well beyond the 500,000 barrels per day provided by the Stage 4 expansion. The objective is to develop an expansion plan that maintains an appropriate resource life based on an independent estimate of Syncrude's reserves and resources as of December 31, 2007. The scoping engineering work on the Stage 3 debottleneck and subsequent expansion stages have been approved and are being developed. Spending will ramp up as the engineering work progresses. The timing of the expansions will depend on the engineering and construction execution plans. It is possible that the debottleneck will be delayed beyond our current 2012 projected startup as could other expansion timing. We plan to provide more information on timing over the next year or two as the scoping work progresses. No cost estimates have been provided for these projects nor have they been approved by the Syncrude owners as they are still in the early planning stages.

As of July 29, 2008 there have been no significant changes to the Trust's contractual obligations and commitments in 2008 from our 2007 year-end disclosure, other than the repayment of approximately $150 million in maturing medium term notes on April 9, 2008.

FINANCIAL RISK MANAGEMENT

The Trust did not have any financial derivatives outstanding at June 30, 2008.

Crude Oil Price Risk

Canadian Oil Sands did not have any crude oil price hedges in place for 2008 or 2007. As at June 30, 2008 the Trust remains unhedged on its crude oil price exposure and does not intend to introduce any crude oil hedge positions. Canadian Oil Sands may, however, hedge its crude oil production in the future depending on the business environment and growth opportunities.

Foreign Currency Hedging

As at June 30, 2008, we do not have any foreign currency hedges in place. At the present time, we do not intend to introduce any currency hedge positions. Canadian Oil Sands may, however, hedge foreign exchange rates in the future, depending on the business environment and growth opportunities.

Interest Rate Risk

Canadian Oil Sands' net income and cash from operating activities are impacted by interest rate changes based on the amount of floating rate debt outstanding. As at June 30, 2008 we did not have any debt outstanding bearing interest at floating market-based rates.

FOREIGN OWNERSHIP

Based on information from the statutory declarations by Unitholders, we estimate that, as of May 16, 2008, approximately 34 percent of our Units are held by non-Canadian residents with the remaining 66 per cent of Units being held by Canadian residents. Canadian Oil Sands' Trust Indenture provides that not more than 49 per cent of its Units can be held by non-Canadian residents.

The Trust regularly monitors its foreign ownership levels through declarations from Unitholders, and the next declarations will be requested as of August 15, 2008. The Trust posts its foreign ownership levels and describes its steps for managing these levels on its web site (www.cos-trust.com) under "Investor Information", "Frequently Asked Questions". These steps are also described in the Trust's AIF.

CROWN ROYALTY CHANGES

In 2007, the Alberta government announced new Crown royalty terms, effective January 1, 2009. For oil sands projects, the new terms are based on a sliding scale royalty rate ranging from one to nine per cent pre-payout and 25 to 40 per cent post-payout that responds to Canadian dollar equivalent WTI ("C$-WTI") price levels. The pre-payout rate starts at one per cent of revenue and increases for every dollar oil is priced above $55 C$-WTI per barrel, to a maximum of nine per cent of revenue at $120 C$-WTI per barrel or higher. The net royalty rate applied post-payout will start at 25 per cent of net revenue and rises for every dollar of C$-WTI increase above $55 C$-WTI per barrel up to a maximum of 40 per cent of net revenue at $120 C$-WTI per barrel or higher.

The Syncrude Joint Venture owners have a Crown royalty agreement with the Alberta government that codifies the current royalty terms of 25 per cent of net SCO revenues to December 31, 2015. The Crown royalty agreement also provides Syncrude with the option to convert to a bitumen-based royalty, consistent with the rest of the industry, prior to 2010. Canadian Oil Sands, as one of the Syncrude owners, is currently in discussions with the Alberta government regarding both the conversion to a bitumen-based royalty and an equitable solution to offset Syncrude's transition to the higher generic royalty rate prior to 2016. Canadian Oil Sands remains of the view that any transition to the new generic royalty terms must recognize our legal rights to the embedded value in Syncrude's contract with the government.

SUSTAINABLE DEVELOPMENT

Waterfowl Incident at Syncrude's Aurora Mine Tailings Pond

In April 2008, a flock of ducks landed and died on one of Syncrude's tailings ponds. Syncrude is cooperating with Alberta Environment and Sustainable Resource Development officials in their investigation into why this occurred. Previous to this event, Syncrude's waterfowl management program, which includes the deployment of noise cannons and scarecrows, has worked very well over decades of use. Syncrude and its owners are very disappointed this occurred and are focused on understanding how to prevent this from happening again.

Greenhouse Gas Emissions Reduction Requirements

On March 31, 2008 Syncrude submitted its 2007 compliance report on greenhouse gas ("GHG") emissions to the Alberta government for review by the director of Alberta Environment. The submission of the compliance report meets the regulatory deadline specified by the Alberta government as part of its Bill 3 legislation introduced in 2007 to reduce GHG emission intensity. Bill 3 states that facilities emitting more than 100,000 tonnes of GHGs a year ("Large Emitters") must reduce their emissions intensity (emissions per unit of production) by 12 per cent over the average emissions intensity levels of 2003, 2004 and 2005. If they are unable to do so, these facilities will be required to pay $15 per tonne for every tonne above the 12 per cent target, beginning July 1, 2007.

For 2008, Syncrude is accruing approximately $0.10 per barrel for compliance with Bill 3, which is reflected in the Trust's operating costs. The cost estimate remains preliminary pending Syncrude's actual carbon dioxide ("CO2") emission intensity level and clarification from the Alberta government regarding details of the Bill 3 implementation. No cost estimates are available for future years.

On March 10, 2008 Canada's federal government provided further detail on its regulatory framework to reduce GHG and air pollutant emissions originally announced on April 26, 2007. The draft regulations are currently expected to be finalized in 2009 and take effect on January 1, 2010. The draft regulations for oil sands projects require existing projects to reduce emissions intensity by 18 per cent in 2010 from the 2006 level and two per cent thereafter. New oil sands facilities coming onstream over the period 2004 to 2011 also will be required to meet clean fuel standards and will be encouraged to implement mechanisms to capture CO2 emissions. In addition to the reduction of existing GHG emissions, the capture and storage of CO2 emissions ("CCS") will be a requirement for all oil sands projects coming onstream post 2012. The draft regulations are expected to impact both current Syncrude operations and its future expansion projects, however the full impact of the regulations cannot be quantified until they are finalized.

Syncrude continues to explore and implement measures to reduce energy intensity in its operations, which reduces both CO2 emissions and operating costs. Syncrude also is exploring the viability of developing a large scale CO2 capture, transportation and storage network through participation in the integrated CO2 Network ("ICON").

Reclamation

In March 2008, the Alberta government certified a parcel of reclaimed land north of Fort McMurray. The 104 hectares, known as Gateway Hill, was submitted by Syncrude to the Alberta government in 2003 for certification. Alberta's Environmental Protection and Enhancement Act requires operators to conserve and reclaim specified land and obtain a reclamation certificate. These certificates are issued to operators when their site has been successfully reclaimed.

Syncrude is the first in the oil sands industry to receive certification for land that has been reclaimed. Syncrude has reclaimed more than 4,500 hectares, representing the largest share in the oil sands industry.

Tailings Management

Syncrude's reclamation efforts also include tailings systems management. Tailings systems are designed to separate water from sand and clay to enable incorporation of solids into reclamation landscapes and recycling of water back into the operations. Syncrude and most other oil sands producers use a method called consolidated tails technology; however, additional tailings management technologies may be required in order to meet the approved closure and reclamation plan. Syncrude is exploring methods to improve and supplement the effectiveness of its tailings systems.

On June 26, 2008, the Alberta Energy Resources Conservation Board ("ERCB") released a draft Directive on Tailings Criteria for public review and comment. This directive proposes to develop new industry-wide criteria to supplement existing regulations by requiring operators to:

- prepare an operations and abandonment plan for every consolidated

tailings pond, which would be reviewed for the establishment of

performance measures by the ERCB;

- operate and abandon each consolidated tailings pond in accordance

with their applications or ERCB approvals;

- consume fine fluid tailings as proposed in their applications or as

approved by the ERCB; and

- specify dates for pond construction, pond use, pond closure, and

other milestones and file these dates with the ERCB by December 31,

2009.

Syncrude is involved in both the review of the draft directive and submission of comments to the ERCB, as well as assessing the impact of the proposed directive on current and future operations. Until the directive is finalized the impact, if any, of the new regulations on Syncrude cannot be fully determined. The regulation as presently drafted, however, is likely to have an adverse impact on the current cost estimates for tailings management.

Syncrude has filed an amendment to its regulatory approval to modify the design of the existing Southwest Sand Storage ("SWSS") facility to permit interim storage of increased volumes of mature fine tailings. Changes to the design of the SWSS facility will be required to increase its fluid storage capacity. The change in design would not increase the footprint of the structure but rather elevate the fluid level within it. Pending regulatory approval, Syncrude intends to make use of this increase in capacity in 2009.

AECO natural gas (Cdn$/GJ) $ 9.50 $ 8.50


The Trust has lowered its 2008 Syncrude production estimate to 106 million barrels to reflect first half results. The estimate continues to incorporate Syncrude's remaining 2008 maintenance program, including the turnaround of Coker 8-2 in the third quarter, an allowance for unplanned outages, and recognition that Syncrude is still working to establish reliable Stage 3 design rates. The Syncrude production estimate is set within a range of 103 to 109 million barrels for 2008.

We have increased our estimate of the Trust's 2008 revenues as a result of increases in the realized SCO sales price. Operating costs estimates have increased as a result of the year-to-date financial results, the expectation of continuing high costs in mining and maintenance operations, increased natural gas prices and the impact of reduced production volumes on the calculation of per Unit costs. The Trust has not assumed any further bitumen purchases in this current Outlook; however, Syncrude may purchase up to 10,000 barrels per day of additional bitumen during the remainder of 2008 to provide for flexibility in SCO production. The increase in forecasted Crown royalties is due to the increased revenues net of increased cost estimates.

As a result of current assumptions, our revised estimate of cash from operating activities has increased to $2,356 million or $4.90 on a per Unit basis. With the increase in the distribution to $1.25 per Unit in the third quarter of 2008, we are estimating net debt levels will remain at approximately $1 billion at the end of 2008.

Distributions paid in 2008 are expected to be 100 per cent taxable as other income. The actual taxability of the distributions will be determined and reported to Unitholders prior to the end of the first quarter of 2009.

Changes in certain factors and market conditions could potentially impact Canadian Oil Sands' Outlook. The following table provides a sensitivity analysis of the key factors affecting the Trust's performance. In addition to the factors described in the table, the supply/demand equation and pipeline access for synthetic crude oil in the North American markets could impact the differential for SCO relative to crude benchmarks; however, these factors are difficult to predict.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE SIX MONTHS ENDED JUNE 30, 2008

(Tabular amounts expressed in millions of Canadian dollars, except where

otherwise noted.)

1) BASIS OF PRESENTATION

The interim consolidated financial statements include the accounts of

Canadian Oil Sands Trust and its subsidiaries (collectively, the

"Trust" or "Canadian Oil Sands"), and are presented in accordance

with Canadian Generally Accepted Accounting Principles ("GAAP"). The

interim consolidated financial statements have been prepared

following the same accounting policies and methods of computation as

the consolidated financial statements for the year ended December 31,

2007, except as discussed in Note 2. Certain disclosures that are

normally required to be included in the notes to the annual audited

consolidated financial statements have been condensed or omitted. The

interim consolidated financial statements should be read in

conjunction with the consolidated financial statements and the notes

thereto in the Trust's annual report for the year ended December 31,

2007.

2) CHANGES IN ACCOUNTING POLICIES

In its consolidated financial statements for the year ended

December 31, 2007, Canadian Oil Sands adopted the requirements of the

Canadian Institute of Chartered Accountants ("CICA") Section 3862

Financial Instruments - Disclosures, Section 3863 Financial

Instruments - Presentation, and Section 1535 Capital Disclosures. The

standards were effective January 1, 2008, however early adoption was

encouraged by the CICA. Additional disclosures required as a result

of adopting the standards can be found in the Trust's consolidated

financial statements for the year ended December 31, 2007.

In June 2007, the CICA issued a new accounting standard - Section

3031 Inventories, which replaces the existing standard for

inventories, Section 3030. The main features of the new Section are

as follows:

- Measurement of inventories at the lower of cost and net

realizable value

- Consistent use of either first-in, first-out or a weighted

average cost formula to measure cost

- Reversal of previous write-downs to net realizable value when

there is a subsequent increase to the value of inventories

The new Section is effective for the Trust beginning January 1, 2008.

Application of the new Section did not have an impact on the

financial statements.

3) FUTURE CHANGES IN ACCOUNTING POLICIES

In February 2008, the CICA issued a new accounting standard - Section

3064 Goodwill and Intangible Assets, which replaces Section 3062

Goodwill and Other Intangible Assets, and Section 3450 Research and

Development Costs. The new section establishes standards for the

recognition, measurement and disclosure of goodwill and intangible

assets. The section is effective for the Trust beginning January 1,

2009. Application of the new section is not expected to have a

material impact on the Trust's financial statements.

4) ISSUANCE OF TRUST UNITS

In the six months ended June 30, 2008, approximately 2.1 million

Trust Units were issued for $24 million on the exercise of employee

stock options.

5) EMPLOYEE FUTURE BENEFITS

Syncrude Canada Ltd. ("Syncrude Canada"), the operator of the

Syncrude Joint Venture, has a defined benefit and two defined

contribution plans providing pension benefits, and other retirement

post-employment benefit plans ("OPEB") covering most of its

employees. Other post-employment benefits include certain health care

and life insurance benefits for retirees, their beneficiaries and

covered dependents. The OPEB plan is not funded.

Canadian Oil Sands accrues its obligations as a joint venture owner

in respect of Syncrude Canada's employee benefit plans and the

related costs, net of plan assets. The cost of employee pension and

other retirement benefits is actuarially determined using the

projected benefit method based on length of service and reflects

Canadian Oil Sands' best estimate of the expected performance of the

plan investment, salary escalation factors, retirement ages of

employees and future health care costs. The expected return on plan

assets is based on the fair value of those assets. Past service costs

from plan amendments are amortized on a straight-line basis over the

estimated average remaining service life of active employees

("EARSL") at the date of amendment. The excess of any net actuarial

gain or loss exceeding 10 per cent of the greater of the benefit

obligation and fair value of the plan assets is amortized over the

EARSL.

Canadian Oil Sands' share of Syncrude Canada's net defined benefit

and contribution plans expense for the three and six months ended

June 30, 2008 and 2007 is based on its 36.74 per cent working

interest. The costs have been recorded in operating expense as

follows:

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


Each of the Trust's credit facilities is unsecured. These credit

agreements contain typical covenants relating to the restrictions on

Canadian Oil Sands' ability to sell all or substantially all of its

assets or to change the nature of its business. In addition, Canadian

Oil Sands has agreed to maintain its total debt-to-total book

capitalization at an amount less than 60 per cent, or 65 per cent in

certain circumstances involving acquisitions.

a) The $40 million extendible revolving term facility is a 364-day

facility with a one-year term out, expiring April 23, 2009. This

facility may be extended on an annual basis with the agreement of

the bank. Amounts borrowed through this facility bear interest at

a floating rate based on bankers' acceptances plus a credit

spread, while any unused amounts are subject to standby fees.

b) The $67 million line of credit is a one-year revolving letter of

credit facility. Letters of credit drawn on the facility mature

April 30th each year and are automatically renewed, unless

notification to cancel is provided by Canadian Oil Sands or the

financial institution providing the facility at least 60 days

prior to expiry. Letters of credit on this facility bear interest

at a credit spread.

Letters of credit of approximately $67 million have been written

against the line of credit as at June 30, 2008.

c) The $800 million operating facility is a five-year facility,

expiring April 27, 2012. Amounts borrowed through this facility

bear interest at a floating rate based on either prime interest

rates or bankers' acceptances plus a credit spread, while any

unused amounts are subject to standby fees. As at June 30, 2008,

no amounts were drawn on this facility.

7) LONG-TERM DEBT

On April 9, 2008, the Trust repaid $150 million of 5.75% medium term

notes.

9) UNITHOLDER DISTRIBUTIONS

The Consolidated Statements of Unitholder Distributions is provided

to assist Unitholders in reconciling cash from operating activities

to Unitholder distributions.

Pursuant to Section 5.1 of the Trust Indenture, the Trust is required

to distribute all the income received or receivable by the Trust in a

quarter less expenses and any other amounts required by law or under

the terms of the Trust Indenture. The Trust primarily receives income

by way of a royalty and interest on intercompany loans from its

operating subsidiary, Canadian Oil Sands Limited ("COSL"). The

royalty is designed to capture the cash generated by COSL, after the

deduction of all costs and expenses including operating and

administrative costs, income taxes, capital expenditures, debt

interest and principal repayments, working capital and reserves for

future obligations deemed appropriate. The amount of royalty income

that the Trust receives in any period has a considerable amount of
