WESTERN OIL SANDS 2007 INTERIM REPORT

for the three-month period ended June 30


TO OUR SHAREHOLDERS
- --------------------------------------------------------------------------------

Western Oil Sands Inc.  ("Western")  announced today its financial and operating
results for the second quarter of 2007.  Western generated net revenue of $187.3
million,  EBITDAX of $98.4 million,  cash flow from  operations of $82.7 million
($0.51 per share) and net  earnings  of $87.5  million  ($0.54 per share) in the
second quarter of 2007.  Net earnings  included $39.2 million ($32.3 million net
of tax) in net unrealized foreign exchange and risk management  (mark-to-market)
gains.

      For the second quarter of 2007, production averaged 30,652 barrels per day
compared  to  15,540  barrels  per  day in the  second  quarter  of  2006.  This
significant  year-over-year  increase  is due in part to the  impact of the full
plant turnaround  which occurred in the second quarter of 2006.  Compared to the
prior year period,  Western's financial performance during the second quarter of
2007 was  positively  impacted by an increase in  production,  offset in part by
lower crude oil price realizations  stemming from an eight per cent drop in West
Texas  Intermediate  ("WTI") prices,  the further  strengthening of the Canadian
dollar  relative  to the US  dollar  and the  widening  of the  heavy  crude oil
differential offset in part by a lighter crude oil sales mix.



HIGHLIGHTS

o     Western  successfully  closed a new $805 million Revolving Credit Facility
      ("Credit  Facility").  The Credit  Facility  was  arranged  by RBC Capital
      Markets with a syndicate of leading  financial  institutions  and replaced
      Western's  existing $340 million  Revolving Credit  Facility.  This Credit
      Facility represents a fundamental component of Western's financing plan as
      we execute on our growth strategy.

o     Western was active with respect to in-situ lease  acquisitions  during the
      quarter  with  the  purchase  of  Leases  418 and 419,  both of which  are
      contiguous to our existing  in-situ  leases.  Western's  operated  in-situ
      acreage position has now grown to  approximately  26,000 acres and we will
      continue  to make  opportunistic  decisions  to add to our asset base over
      time. Over the balance of the year, Western will be assessing the resource
      potential  associated  with our in-situ  project as well as the Ells River
      Project with the assistance of independent evaluators.  These results will
      be communicated as part of our year-end reporting requirements.

o     The Joint Venture  Owners  continue to make progress on Expansion 1 of the
      AOSP.  Construction  and  engineering  of both the upstream and downstream
      components  remain on budget and on  schedule  with  first oil  production
      anticipated in the fall of 2010. Several of the large vessels have arrived
      at the Scotford  Upgrader  site while key  foundation  and  infrastructure
      groundwork is well underway at the Mine.




o     Effective  August  1,  2007,  Mr.  Robert  Theriault  joins  WesternZagros
      Resources Inc.  ("WesternZagros"),  our wholly-owned subsidiary, as Senior
      Vice President, Engineering and Operations. Robert will be instrumental in
      overseeing  engineering  and  operations in  Kurdistan.  He brings over 30
      years of international  and domestic  experience in upstream and midstream
      oil and gas operations,  including senior management  responsibilities for
      exploration,  production and development.  With the addition of Robert and
      other recent new employees in  geophysical,  geotechnical  and  operations
      disciplines,  Western has  developed a  stand-alone  organization  for its
      Kurdistan   initiative.   This  team  will  continue  to  be  enhanced  as
      exploration and development activities progress.

Operating Results
- --------------------------------------------------------------------------------

Production

During the second  quarter of 2007,  Western's net bitumen  production  averaged
30,652  barrels  per day,  nearly  double the  average  15,540  barrels  per day
recorded  in  the  second  quarter  of  2006.  This   substantial   increase  is
predominantly  due to the impact of ceasing the entire  operation  for the first
full plant turnaround which occurred in the second quarter of 2006.  Compared to
the first quarter of 2007, second quarter production  decreased by approximately
five per cent. This slight decrease is mainly due to planned and minor unplanned
outages during the quarter. Planned outages resulted from unit tie-ins including
the new  closed  loop  water  cooling  plant at the Mine  which is  expected  to
increase the operational efficiency. There was also a planned outage at the Mine
resulting from the power tie-in of another oil sands project to the  electricity
grid.

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

(1)  Oil Sands Revenue and Net Revenue are  presented  net of Western's  hedging
     activities.
(2)  Realized  Crude Oil Sales Price  ($/bbl) is calculated as Oil Sands Revenue
     less any  transportation  costs divided by total  Synthetic Crude Sales for
     the period. For the three months ended June 30, 2007, $0.1 million (Q2-2006
     -$0.3  million) has been incurred for  transportation  costs related to Oil
     Sands.

     Western more than doubled its crude oil sales revenue to $341.4  million in
the second  quarter of 2007 compared to $165.7 million in the prior year period.
Crude oil sales revenue during the quarter included $237.5 million from the sale
of  proprietary  production  compared to $137.1 million in the second quarter of
2006. The significant increase in revenue compared to the prior year period is a
result of lower  production  levels  associated  with the full plant  turnaround
which in turn  impacted  revenue,  offset in part by lower per  barrel  realized
sales  prices  due to a  widening  of the  heavy  crude oil  differential  and a
strengthening  of the  Canadian  dollar  relative  to the US  dollar by over two
cents.

     Western  generated net revenue of $187.3  million in the second  quarter of
2007, after  considering the impact of purchased  feedstocks and  transportation
costs  downstream of Edmonton.  By comparison,  net revenue of $95.6 million was
recorded  in the  second  quarter  of 2006.  Feedstocks  are crude oil  products
introduced   into  the   hydrocracking/hydrotreating   process  and  blendstocks
introduced  into  synthetic  crude oil  products.  The cost of these  feedstocks
varies with world oil markets and the spread  between  heavy and light crude oil
prices.

     Oil sands sales volumes,  which include  bitumen and purchased  feedstocks,
averaged 40,250 barrels per day in the second quarter of 2007 compared to 22,614
barrels  per day in the second  quarter of 2006.  This  significant  increase is
largely due to the lower  activity in the second quarter of 2006 due to the full
plant turnaround.

     During the second  quarter of 2007,  WTI crude oil  averaged  US$65.03  per
barrel,  representing  a 12 per cent increase over the first quarter of 2007 but
an eight per cent  decrease  compared  to the prior year  period.  Edmonton  PAR
prices  increased  seven per cent in the second  quarter of 2007 compared to the
first quarter of 2007.  This increase  corresponds to a similar  increase in WTI
prices over the comparable time period,  however,  not to the same magnitude due
to the  strengthening  of the  Canadian  dollar  relative  to the US dollar.  As
Western measures its blended  differential to Edmonton PAR, the strengthening of
the US/Cdn exchange rate reduces overall sales price realizations.



     Western's  blended  realized crude oil sales price was $64.79 per barrel in
the  second  quarter  of 2007  compared  to $66.48  per barrel in the prior year
period.  Sales price  realizations  increased by $6.30 per barrel from the first
quarter  of 2007.  Compared  to the  prior  year  period,  the  heavy  crude oil
differential  as a  percentage  of WTI  widened  to  approximately  33 per  cent
(US$21.00) from 26 per cent (US$18.00).  Consequently,  Western received a lower
netback on its share of heavy crude oil production  from the Project.  The heavy
crude oil  differential as a percentage of WTI narrowed in the prior year period
as a result of reduced  demand for Canadian  heavy crude oil by US refineries as
many of them were  undertaking  normal  maintenance  programs  and  turnarounds;
however, the heavy crude oil differential remained relatively unchanged compared
to the first quarter of 2007.

     The impact of the wider heavy crude oil  differential on Western's  blended
sales price  differential  was more than offset by the  production  of a lighter
overall sales mix. Over the last several quarters,  the Project has continued to
make  improvements  on the  conversion  process  at the  Upgrader  as capital is
deployed to improve  efficiency  and  availability.  This  results is a narrower
Western sales price  differential.  Combined  with external  market forces which
increased the price Western  receives on its Premium  Albian  Synthetic  ("PAS")
stream,  Western  achieved its lowest  blended  differential  as a percentage of
Edmonton PAR since the commencement of operations.

Operating Costs

Western  reported cash  operating  costs of $24.92 per processed  barrel for the
second quarter of 2007. Unit operating costs in the quarter reflect the combined
effect of lower production volumes relative to the first quarter of 2007 as well
as decreased  natural gas prices. In addition,  higher  expenditures on contract
services for  maintenance at the Mine and wage  escalation  also  contributed to
higher operating costs during the quarter.  By comparison,  operating costs were
$24.07 per  processed  barrel  for the first  quarter of 2007 and $39.44 for the
second quarter of 2006 excluding the costs of the  turnaround,  but  considering
significantly  lower  volumes.  Approximately  70 to 75 percent of the operating
cost structure is fixed for the AOSP,  therefore,  volume variances  account for
significant fluctuations in reported unit costs.

     Compared  to the first  quarter  of 2007,  unit  operating  costs  remained
relatively consistent as decreases in natural gas prices were essentially offset
by lower economies of scale caused by lower production levels.

(1)  Operating  Expenses Per  Processed  Barrel  ($/bbl) is  calculated as Total
     Operating  Expenses  For  Bitumen  Sold  divided by  Synthetic  Crude Sales
     Excluding Blend Stocks.

     The above table calculates  operating  expenses per processed barrel on the
basis of the operating costs that are associated with the synthetic crude sales,
excluding  purchased  blendstocks,  for the  relevant  period.  The  calculation
recognizes that, intrinsic in the Project's operations,  bitumen production from
the Mine  receives  an  approximate  three  per cent  uplift  as a result of the
hydrotreating/hydroconversion  process,  which is  included in  synthetic  crude
sales excluding blendstocks.



Royalties

Royalties of $1.2 million were  recorded in the second  quarter of 2007 compared
to $0.7 million in the second quarter of 2006. This year-over-year  increase was
due to the lower  production  associated  with the full turnaround in the second
quarter of 2006 offset in part by lower deemed bitumen royalty prices.  Compared
to the first  quarter of 2007,  royalty  expenditures  are  comparable  as lower
production levels were offset by higher deemed bitumen prices.

     Royalties  are  calculated  at one per cent of the gross  revenue  from the
bitumen  produced (based on its deemed value prior to upgrading)  until recovery
of all capital  costs  associated  with the Muskeg River Mine,  together  with a
return on capital equal to the  Government of Canada's  federal  long-term  bond
rate.  After full  Muskeg  River Mine  capital  cost  recovery,  the  royalty is
calculated  as the  greater of one per cent of the gross  revenue on the bitumen
produced  or 25 per cent of the net  revenue on the  bitumen  produced  based on
deemed bitumen prices.

     Western anticipates a conversion to the 25 per cent of net bitumen revenues
in July 2007 until such time as the AOSP's  Expansion 1 royalties  submission is
reviewed  and ruled  upon.  Should the royalty  submission  be  successful  then
retroactive  adjustment  to the royalty rate will be made.  Ultimately,  Western
assumes that additional  capital incurred to construct future expansions will be
added to the capital base for royalty purposes, extending our royalty horizon in
the absence of any legislative amendments to the royalty regime.

     The  Alberta  government  announced  a review of the oil and gas  royalties
including  oil sands.  A panel has been  selected  and  recommendations  will be
submitted to the  government  by August 31, 2007.  Western,  along with industry
through their  representation in the Canadian Association of Petroleum Producers
("CAPP"),  is actively  participating  in the review process in order to present
the  opportunities,   challenges,   and  economics  associated  with  oil  sands
development today and in the future.


Corporate Results
- --------------------------------------------------------------------------------

Research, Business Development and Other Expense

Western  incurred  $11.7  million in research,  business  development  and other
expenses  in  the  second  quarter  of  2007,  $6.3  million  of  which  relates
specifically  to  AOSP-related  research  and  development  projects.  The $11.7
million  compares  to $7.7  million  recorded  for the prior  year  period.  The
increase  is  the  result  of  additional   efforts  in  research  and  business
development  surrounding  heavy  minerals and field  upgrading  technologies  in
addition to  increased  allocations  of  corporate  general  and  administrative
expenses associated with business teams focused on our Kurdistan oil opportunity
and in-situ (Western-operated and Chevron Ells River) initiatives.

General and Administrative Expense

General and  administrative  expenses  ("G&A")  were $5.6 million for the second
quarter of 2007, net of allocations to Kurdistan and in-situ divisions, compared
to $5.3 million  (restated for EIC-162  treatment for stock-based  compensation)
for the second  quarter of 2006. G&A reported for the second quarter of 2006 was
restated by $2.1 million with the adoption of EIC 162. Moderate increases in G&A
levels are due to inflationary pressures. Western allocates a portion of its G&A
expenses  that are directly  related to our  Kurdistan  opportunity  and in-situ
initiatives to Research and Business Development, as explained above.

Insurance Expense

Insurance  expenses were $3.3 million in the second  quarter of 2007 compared to
$2.7  million in the second  quarter of 2006.  Insurance  expenses  were  higher
compared to the prior year period due to  additional  premiums  associated  with
increased levels of coverage, offset by the strengthening of the US/Cdn exchange
rate as the premiums are paid in US dollars but reported for financial statement
purposes in Canadian dollars.



Interest Expense

During the second quarter of 2007,  financing charges totaled $15.1 million,  of
which $8.1  million  represents  capitalized  interest  relating to Expansion 1.
Capitalized  interest  will  increase  in the  future  as we  expect to employ a
combination  of cash flow and debt  financing  to fund our share of the  capital
costs of Expansion1.  Total financing charges  represents a 20 per cent increase
from the $12.5 million  incurred for financing  charges in the second quarter of
2006.  Interest expense for the three months ended June 30, 2007 is comprised of
$12.9  million  (Q2-2006 - $10.9  million)  related to interest  charges on debt
obligations, $0.7 million (Q2-2006 - $0.6 million) on capital lease obligations,
$0.9 million  (Q2-2006 - $0.9 million) on the option premium  liability and $0.6
million  (Q2-2006 - nil) for  amortization of debt financing  costs.  The option
premium  liability  relates to  Western's  strategic  crude oil risk  management
program  implemented  in the third  quarter  of 2005,  and the  deferral  of the
premiums   associated  with  the  put  and  call  options  purchased  and  sold,
respectively.  Imbedded  in the prices of the  deferred  options is a  financing
charge which is reported as interest expense.

     The 20 per cent increase in total financing  charges compared to the second
quarter of 2006 is primarily a function of Western  carrying  larger balances in
its Revolving Credit Facility associated with funding our share of capital costs
for Expansion 1. This increase was partially offset by the  strengthening of the
US/Cdn exchange rate,  thereby  reducing  interest charges on our US denominated
Notes which are reported in Canadian  dollars.  Financing  charges  increased by
$0.5 million in the second quarter of 2007 compared to the first quarter of 2007
due to higher levels of debt partially  offset by a strengthening  of the US/Cdn
exchange rate.  Western's total interest  charges will increase over the balance
of 2007,  and over the next several  years,  as we continue to fund our share of
the anticipated capital costs through a combination of cash flow from operations
and  incremental  borrowings.  Western  will  continue  to  assess  our  funding
requirements  for our capital programs and revise our financing plan accordingly
as part of our normal  course  business.  Western's  new $805 million  Revolving
Credit  Facility  (the  "Credit  Facility")  represents  a key  component of our
financing  plan for Expansion 1 as well as future AOSP  expansions and other key
initiatives.  Interest  rates  charged  pursuant  to the Credit  Facility  are a
function of external credit rating  agencies'  assessment of the Credit Facility
with spreads ranging from nil to 145 basis points.

Depreciation, Depletion and Amortization

Depreciation,  depletion and amortization ("DD&A") totaled $12.7 million for the
second  quarter of 2007 compared to $6.8 million in the second  quarter of 2006.
Since the majority of DD&A depends on production  levels,  the second quarter of
2006 was  lower  due to the  impact of the full  plant  turnaround.  Incremental
reserves  associated  with Expansion 1 will not be included in the  depreciation
rate until the assets associated with this expansion  commence  operations which
is anticipated in 2010.

Foreign Exchange

During the second quarter of 2007,  Western  reported a foreign exchange gain of
$41.4 million compared to a gain of $25.8 million in the second quarter of 2006.
This gain is the result of a strong Canadian dollar relative to the US dollar at
the end of the quarter  compared to the  month-end  rate at the end of the first
quarter  of 2007,  and it  results  in a lower  Canadian  equivalent  amount  on
Western's US$450 million  long-term debt and deferred option premium  liability.
Over the quarter,  the Canadian dollar has appreciated over seven cents relative
to the US dollar.  As reference  points,  the noon-day  foreign exchange rate on
June30, 2007 was $0.9404 US/Cdn compared to $0.8674 US/Cdn on March 31, 2007 and
$0.8969 US/Cdn on June 30, 2006. The average rate for the second quarter of 2007
was  $0.9106  US/Cdn  compared  to $0.8912  US/Cdn for the prior year period and
$0.8537 US/Cdn for the first quarter of 2007.




Risk Management Activities

Western paid $5.9 million in option  premiums  during the second quarter of 2007
associated with its strategic crude oil hedging program  implemented in the fall
of 2005.  In the second  quarter crude oil traded within the band of US$52.42 to
US$92.41 per barrel  established  by the  pay-collar  structure and therefore no
additional amounts were paid or received.  Premiums are funded by cash flow from
operations and incurred on a monthly basis as a result of Western's  decision to
defer the premiums at the time of the original execution.

     Western is not utilizing hedge accounting treatment under Canadian GAAP for
this program and, as a result, certain  mark-to-market  adjustments flow through
our financial statements.  These adjustments are created from the changes in the
fair market value of the financial  instruments employed over the time period in
question.  For the quarter ended June 30, 2007, Western's risk management assets
decreased in value from the amount  recorded as at March 31, 2007. This resulted
in a mark-to-market loss of $6.4 million ($8.0 million net of tax) primarily due
to the strengthening in WTI prices during the quarter partially offset with less
time value associated with the options as they approach maturity. This loss does
not impact stated cash flow from operations.

Income Taxes

In the second  quarter of 2007,  Western  recorded  income tax  expense of $23.8
million  compared  to an income tax  recovery of $25.5  million  during the same
period last year.  The recovery in the second  quarter of 2006 largely  resulted
from the  turnaround  and risk  management  losses.  The  expense for the second
quarter of 2007 was  primarily  the  result of  increased  profitability  due to
increased production levels and the absence of turnaround costs partially offset
by the federal income tax rate reduction  passed by the House of Commons on June
12, 2007.

     During the first quarter of 2007, the Canadian Federal Government announced
its intent to phase out the  Accelerated  Capital Cost Allowance  ("ACCA") which
previously  allowed oil sands companies to claim a higher amount against taxable
income than normally  permitted for assets of this nature.  Western  anticipates
that capital associated with base operations and Expansion 1 will be included in
the ACCA pool with the ability to claim in excess of 25 per cent, subject to the
extent of taxable income from that operation.  The impact of tax  classification
with respect to ACCA for Expansions 2 and beyond is uncertain at thistime.

Net Earnings

During the second  quarter  of 2007,  Western  reported  net  earnings  of $87.5
million  ($0.54 per share)  compared to a net loss of $23.0  million  ($0.14 per
share) in the second quarter of 2006. Net earnings in the second quarter of 2007
included  the impact of $6.4  million  ($8.0  million net of tax  including  the
impact of removing $5.9 million of tax  deductible  option  premiums paid in the
quarter) in risk management  losses, in addition to $41.4 million ($37.4 million
net of tax) in  foreign  exchange  gains on our US dollar  denominated  debt and
option premium liability.

second  quarter of 2007,  representing  a  thirteen-fold  increase over the $8.2
million  EBITDAX loss recorded for the second quarter of 2006.  This increase is
due in large part to the impact of the full plant  turnaround  during the second
quarter of 2006. Second quarter 2007 EBITDAX increased $17.3 million compared to
the first  quarter of 2007 and is largely  the result of  improved  sales  price
realizations  from the  prior  quarter,  partially  offset  by lower  production
stemming from planned maintenance events.




     Cash flow from operations before changes in non-cash working capital ("cash
flow from operations") was $82.7 million for the second quarter of 2007 compared
to a cash use of $20.9  million in the prior year  period.  Second  quarter 2007
cash flow from  operations  increased  $19.7  million over the first  quarter of
2007. This increase is again the result of higher sales price  realizations  due
to higher over WTI prices  together  with the  production of a lighter sales mix
partially offset by lower production levels.


Financial Position
- --------------------------------------------------------------------------------

Bank Debt

During the second quarter of 2007, Western  successfully  implemented a new $805
million  Revolving  Credit  Facility which  replaces the $340 million  Revolving
Credit  Facility.  The term of the new Credit  Facility is initially  five years
which can be extended  annually at the  discretion  of the lenders.  It has been
rated BBB by  Standard & Poor's  ("S&P")  and Ba2 by Moody's  Investor  Services
("Moody's").  S&P had previously upgraded the rating on Western's US$450 million
Notes ("Notes") to BBB, while Moody's upgraded the Notes to Ba2 as part of their
rating of the Credit Facility. Western's improved credit profile is reflected in
these  upgraded  ratings as we continue to move  towards a corporate  investment
grade classification.

     During the quarter,  Western drew an  additional  $85 million on its credit
facilities,  bringing the  outstanding  drawn balance to $214 million as at June
30, 2007.  Additional  amounts drawn were used to partially fund Western's share
of capital expenditures for Expansion 1 during the quarter.  With the new Credit
Facility  in place,  as at June 30,  2007,  the  undrawn  capacity of the Credit
Facility totaled $591 million, excluding amounts allocated to letters of credit.

     Western's  debt to  total  capitalization  as at June  30,  2007  decreased
slightly to 47 per cent from 49 per cent  largely due to the benefit  associated
with  a  significant   strengthening  of  the  US/Cdn  exchange  rate.   Western
anticipates  the extent of  leverage  will  increase  as we continue to fund our
share of capital  expenditures  for  Expansion  1,  together  with our other key
growth  initiatives,  through a  combination  of cash flow from  operations  and
incremental borrowings.


Capital Expenditures

Western's capital  expenditures  totaled $166.5 million in the second quarter of
2007  compared  to $55.8  million  for the  comparable  period in 2006.  Capital
expenditures  in the second  quarter of 2007  included  $11.4  million  for base
operations,  $5.0 million for sustaining  capital,  $134.9 million for expansion
related  capital  including  capitalized  interest,   $6.0  million  related  to
Kurdistan,  $4.3 million for Western's in-situ  initiatives and $4.9 million for
other minor corporate  expenditures.  Corporate expenditures primarily relate to
capitalized   legal  costs  associated  with  Western's   Section  IV  insurance
arbitration proceedings.


Analysis of Cash Resources

Cash balances  totaled $4.4 million at June 30, 2007 compared to $6.0 million at
June  30,  2006.  Cash  inflows  included:  $82.7  million  in  cash  flow  from
operations,  $85.0 million from Credit Facility  drawdowns and $1.3 million from
the  exercise  of  employee  stock  options.  Cash  outflows  included:  capital
expenditures  of $166.5  million,  $3.4  million for  deferred  charges and $0.3
million repayment of obligations under capital lease.

     There was a negligible  change in working capital during the second quarter
of 2007.  Reductions  to working  capital  included a $3.8  million  increase in
accounts  receivable  and a $2.4 million  reduction in accounts  payable.  These
changes were essentially  offset by a $4.1 million  reduction in inventory and a
$2.1million decrease in prepaid expenses. The increase in accounts receivable is
the result of higher sales price realizations. The reduction in accounts payable
primarily  relates to only two months of accrued interest on Western's US dollar
long-term  notes  being  included at June 30, 2007 versus five months of accrued
interest at March 31, 2007.



Insurance Claims

There were no new  significant  developments  during the second  quarter of 2007
with respect to Western's ongoing  arbitration  proceedings  concerning the Cost
Overrun  and  Project  Delay  insurance  policy,  known as Section  IV.  Western
anticipates  that formal  arbitration  hearings will commence in September 2007.
Amounts owing under all Western's insurance claims total $244 million as of June
30, 2007 not including  interest and ongoing costs which could add significantly
to the balance to be considered by the arbitration panel.


Flow-Through Shares

As  communicated  during 2006, the Canada  Revenue  Agency  ("CRA")  proposed to
challenge the characterization of certain  expenditures  capitalized as Canadian
Exploration  Expense ("CEE") which  were incurred in 2001 and 2002 and renounced
to subscribers of the  flow-through  share  offerings  equaling $29.2 million in
2001 and $19.5 million in 2002.  Western has yet to be formally  reassessed  and
continues to work with the other Joint Venture Owners to seek resolution of this
potential  challenge.  If the CRA is  successful  in  assessing  a change in the
characterization  of these  expenditures,  the resulting  reduction would impact
Western's  obligations  under  the  indemnity  provisions  in  the  subscription
agreements  for the  flow-through  shares and, in turn,  would impact  Western's
reported results.


Outlook for the Remainder of 2007
- --------------------------------------------------------------------------------

Western   anticipates   its  share  of  production  from  the  AOSP  to  average
approximately  31,000  to 34,000  barrels  per day in 2007  based on  production
performance for the first half of 2007.

     Western will continue to make  opportunistic  business  decisions to add to
our oil sands lease  position  over time.  This  initiative,  combined  with the
AOSP's existing lease position,  provides a strong platform for Western's future
growth.  Western  continues to pursue  downstream  integration  opportunities to
maximize value from our oil sands  resources and undeveloped  acreage  position.
Western's advisors,  Goldman,  Sachs & Co. and TD Securities Inc., are assisting
in these  activities  under the oversight of an ad hoc committee of  independent
directors of the Board.  Western's Board and management team remain committed to
maximizing the value of its Canadian oil sands position.

     WesternZagros,  our  wholly-owned  subsidiary,  continues  to  advance  its
opportunity  in the  Federal  Region of  Kurdistan.  A seismic  program has been
initiated with over 350 kilometres completed to date of an initial 650 kilometre
program.  In addition,  WesternZagros  continues  to augment its  organizational
capabilities in order to support this initiative.

AOSP Expansion 1 Update

Engineering, procurement and construction activity continues to proceed on plan.
Detailed  engineering at the Mine is well over 50 per cent complete.  During the
quarter, key  Mine  construction  efforts were focused on the  completion of the
Albian Village and the Primary  Separation Cell  foundation,  progression of the
deep  undergrounds  and  commencement  of  structural  erection  works.  At  the
Upgrader,  engineering,  construction  and procurement  activities are following
plan. A key  milestone  for the  Upgrader  during the quarter was the arrival of
three of the five large reactor vessels  fabricated in Italy, with the remaining
two reactors  arriving in July 2007.  The Corridor  Pipeline  expansion  also is
progressing  with a significant  amount of pipe already  completed.  The Project
Owners are closely monitoring the ongoing labour  negotiations with the building
trades.  To  this  point,  there  have  been no  labour  disruptions  at  either
construction  site and the Joint Venture Owners look forward to working with the
various  trade unions to ensure a peaceful  labour  environment  on our Project.
Clearly,  we  would be  disappointed  with any  labour  disruption.  In terms of
safety,  the Project has surpassed seven million man hours without one lost-time
incident.



     Western's   recently  closed  Credit  Facility   represents  a  fundamental
component of our financing strategy for Expansion 1. As previously communicated,
we believe our share of the capital expenditures associated with Expansion 1 can
be funded  through a combination of cash flow from  operations  and  incremental
borrowings.  Further  financing  efforts  will  be  required  to  round  out our
comprehensive  financing  plan which will  position  Western to meet our ongoing
commitments for this first 100,000 barrel per day expansion.


Business and Financial Risks
- --------------------------------------------------------------------------------

Western is subject to a number of business and financial  risks that are typical
given the nature of Western's operations. These risks are described in Western's
previous  public  disclosures,  including  the 2006  Annual  Report  and  Annual
Information Form, which are available on the Company's website and SEDAR.


Non-GAAP Financial Measures
- --------------------------------------------------------------------------------

Western includes cash flow from operations per share,  cash flow from operations
excluding hedging  activities,  earnings before interest,  taxes,  depreciation,
depletion  and  amortization,   stock-based  compensation,  accretion  on  asset
retirement  obligation,  foreign  exchange  gains  and  gains or  losses on risk
management activities ("EBITDAX"),  EBITDAX excluding hedging activities and net
earnings  excluding hedging  activities as investors may use this information to
better  analyze our operating  performance.  We also include  certain per barrel
information, such as realized crude oil sales price, to provide per unit numbers
that can be compared  against  industry  benchmarks,  such as the  Edmonton  PAR
benchmark.  The additional  information should not be considered in isolation or
as a substitute  for measures of operating  performance  prepared in  accordance
with  Canadian  Generally  Accepted  Accounting  Principles  ("GAAP").  Non-GAAP
financial  measures do not have any standardized  meaning prescribed by Canadian
GAAP and are therefore  unlikely to be comparable to similar measures  presented
by other  issuers.  Management  believes  that,  in addition to Net Earnings per
Share and Net Earnings  Attributable to Common  Shareholders (both Canadian GAAP
measures),  cash flow from  operations  per share and  EBITDAX  provide a better
basis  for   evaluating  our  operating   performance,   as  they  both  exclude
fluctuations on the US dollar denominated Senior Secured Notes and certain other
non-cash items,  such as depreciation,  depletion and  amortization,  and future
income tax recoveries.  In addition,  EBITDAX provides a useful indicator of our
ability to fund our financing costs and any future capital requirements.


Changes in Accounting Policies
- --------------------------------------------------------------------------------

Stock-based  Compensation  for  Employees  Eligible to Retire Before the Vesting
Date

For the year ending December 31, 2006,  Western  retroactively  adopted Emerging
Issues Committee Abstract 162 ("EIC-162"). EIC-162 required Western to recognize
stock-based  compensation  expense for awards granted to employees  eligible for
retirement under  stock-based  compensation  plans that contain  provisions that
allow an employee to continue  vesting in an award in accordance with the stated
vesting  terms  after  the  employee  has  retired.   Accordingly,   stock-based
compensation expense for the three and six month periods ended June 30, 2006 was
increased by $0.2 million and $3.4  million,  respectively,  included in general
and administrative  expense,  representing the additional  compensation  expense
recognized for employees eligible for retirement during the vesting period.



Financial Instruments

On January 1, 2007,  Western adopted the CICA Handbook  sections 3855 "Financial
Instruments  -  Recognition  and  Measurement,"  3862  "Financial  Instruments -
Disclosures," 3863 "Financial  Instruments - Presentation,"  3865 "Hedges," 1530
"Comprehensive  Income,"  and 3251  "Equity."  Other than the effect on Deferred
Charges as described  under  Financial  Instruments  below,  the adoption of the
financial  instruments  standards  have not affected the current or  comparative
period  balances  on the  consolidated  financial  statements  as all  financial
instruments identified have been fair valued.

     Section  3855  requires   that  all  financial   assets  be  classified  as
held-for-trading, available-for-sale, held-to-maturity, or loans and receivables
and that all financial  liabilities  must be classified as  held-for-trading  or
other. Financial assets and financial liabilities classified as held-for-trading
are  measured  at fair value with  changes in those fair  values  recognized  in
earnings.  Financial assets held-to-maturity,  loans and receivables,  and other
financial  liabilities  are  measured  at  amortized  cost  using the  effective
interest  method  of  amortization.   Available-for-sale  financial  assets  are
measured at fair value with unrealized  gains and losses,  including  changes in
foreign  exchange  rates,  being  recognized  in  other  comprehensive   income.
Investments in equity instruments  classified as available-for-sale  that do not
have a quoted market price in an active market are measured at cost.

     Derivative  instruments  are always  carried at fair value and  reported as
assets where they have a positive fair value and as liabilities  where they have
a  negative  fair  value.   Derivatives  may  be  embedded  in  other  financial
instruments. Under the new Financial Instrument standards,  derivatives embedded
in other  financial  instruments are valued as separate  derivatives  when their
economic  characteristics and risks are not clearly and closely related to those
of the host contract; the terms of the embedded derivative are the same as those
of a free  standing  derivative;  and the  combined  contract  is not  held  for
trading.  When an entity is unable to  measure  the fair  value of the  embedded
derivative separately,  the combined contract is treated as a financial asset or
liability  that is  held-for-trading  and  measured  at fair value with  changes
therein recognized in the earnings.

     The fair value of a financial instrument on initial recognition is normally
the  transaction  price,  i.e.  the  fair  value of the  consideration  given or
received.  Subsequent  to initial  recognition,  fair values are based on quoted
market prices where  available  from active  markets,  otherwise fair values are
estimated based upon market prices at reporting date for other similar assets or
liabilities with similar terms and conditions, or by discounting future payments
of interest and principal at estimated interest rates that would be available to
Western at the reporting date.

     Transaction  costs are  expensed  as  incurred  for  financial  instruments
classified or designated as held-for-trading. Transaction costs related to other
financial  instruments are generally capitalized and are then amortized over the
expected  life  of  the  instrument   using  the  effective   interest   method.
Accordingly,  the  Deferred  Charges  balance of $13.5  million,  consisting  of
transaction costs relating to the Senior Secured Notes, was reclassified against
Long-term Debt effective January 1, 2007 under prospective application.  For the
three  month  period  ended June 30,  2007,  $0.6  million  of these  costs were
included in interest expense under the effective interest method.

     Emerging Issues Committee  Abstract 101 ("EIC-101") states that transaction
costs  relating to line of credit and revolving debt  arrangements  are excluded
from Section 3855.  Transaction  costs of $3.4 million  relating to the new $805
million  Revolving  Credit Facility are being amortized using the  straight-line
method over the five year term of the Revolving Credit Facility.

Hedges

Section 3865 replaces the guidance  formerly in Section 1650,  "Foreign Currency
Translation" and Accounting Guideline 13, "Hedging  Relationships" by specifying
how hedge  accounting is applied and what  disclosures  are necessary when it is
applied.  Western does not have any derivative  instruments  that are subject to
hedge accounting.



Comprehensive Income

Section  1530   establishes   new   standards   for  reporting  the  display  of
comprehensive  income,  consisting of net income and Other Comprehensive  Income
("OCI").  OCI is the change in equity  (net  assets) of an  enterprise  during a
reporting period from  transactions and other events from non-owner  sources and
excludes those resulting from investments by owners and distributions to owners.
Western has no such transaction and events which would require the disclosure of
OCI for the three and six month  periods  ended June 30,  2007.  Any  changes in
these items would be presented  in a  consolidated  statement  of  comprehensive
income.

Equity

Section 3251 replaces Section 3250, "Surplus" and establishes  standards for the
presentation  of  equity  and  changes  in  equity  during a  reporting  period,
including changes in Accumulated Other Comprehensive Income ("Accumulated OCI").
Any  cumulative  changes  in OCI would be  included  in  Accumulated  OCI and be
presented as a new category of Shareholder's  Equity on the consolidated balance
sheets.

Accounting Changes

On January 1, 2007,  Western  adopted CICA Handbook  Section  1506,  "Accounting
Changes",  which revises and replaces former Section 1506, "Accounting Changes".
The Section establishes criteria for changing accounting policies, together with
the accounting  treatment and  disclosure of changes in accounting  policies and
estimates, and correction of errors.

Determining the Variability to be Considered in Applying AcG-15

On January 1, 2007, Western  prospectively adopted the Emerging Issues Committee
issued  Abstract163,  "Determining  the Variability to be Considered in Applying
AcG-15",  which addresses how an enterprise  should determine the variability to
be considered in applying AcG-15, "Consolidation of Variable Interest Entities".
The adoption of this standard has not affected the current or comparative period
balances on the consolidated financial statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited) (Tabular amounts in $ thousands, except for share amounts)


The interim  consolidated  financial  statements include the accounts of Western
Oil Sands Inc. and its subsidiaries  (the  "Corporation"),  and are presented in
accordance with Canadian Generally Accepted Accounting  Principles.  The interim
consolidated  financial  statements have been prepared using the same accounting
policies  and  methods of  computation  as the  audited  consolidated  financial
statements for the year ended  December 31, 2006,  except as described in Note1.
The  disclosures  provided below are incremental to those included in the annual
consolidated financial statements. The interim consolidated financial statements
should be read in conjunction with the consolidated financial statements and the
notes thereto in the Corporation's annual report for the year ended December 31,
2006.


Note 1. Changes in Accounting Policies
- --------------------------------------------------------------------------------

a)   Stock-based  Compensation  for  Employees  Eligible  to Retire  Before  the
     Vesting Date

For the year ended  December 31, 2006,  the  Corporation  retroactively  adopted
Emerging  Issues  Committee  Abstract  162  ("EIC-162").  EIC-162  required  the
Corporation to recognize stock-based  compensation expense for awards granted to
employees  eligible for retirement  under  stock-based  compensation  plans that
contain  provisions  that allow an employee  to continue  vesting in an award in
accordance  with the  stated  vesting  terms  after the  employee  has  retired.
Accordingly,  stock-based  compensation  expense  for the  three  and six  month
periods  ended June 30, 2006 was  increased  by $0.2  million and $3.4  million,
respectively,  included in general and administrative expense,  representing the
additional compensation expense recognized for employees eligible for retirement
during the vesting period.

b)   Financial  Instruments

On January 1, 2007,  the  Corporation  adopted the CICA  Handbook  sections 3855
"Financial   Instruments  -  Recognition  and   Measurement,"   3862  "Financial
Instruments - Disclosures,"  3863 "Financial  Instruments - Presentation,"  3865
"Hedges," 1530 "Comprehensive  Income," and 3251 "Equity." Other than the effect
on Deferred Charges as described under Financial Instruments below, the adoption
of  the  financial  instruments  standards  has  not  affected  the  current  or
comparative  period  balances on the  consolidated  financial  statements as all
financial instruments identified have been fair valued.

     Financial  Instruments

Section   3855   requires   that  all   financial   assets  be   classified   as
held-for-trading, available-for-sale, held-to-maturity, or loans and receivables
and that all financial  liabilities  must be classified as  held-for-trading  or
other. Financial assets and financial liabilities classified as held-for-trading
are  measured  at fair value with  changes in those fair  values  recognized  in
earnings.  Financial assets held-to-maturity,  loans and receivables,  and other
financial  liabilities  are  measured  at  amortized  cost  using the  effective
interest  method  of  amortization.   Available-for-sale  financial  assets  are
measured at fair value with unrealized  gains and losses,  including  changes in
foreign  exchange  rates,  being  recognized  in  other  comprehensive   income.
Investments in equity instruments  classified as available-for-sale  that do not
have a quoted market price in an active market are measured at cost.

     Derivative  instruments  are always  carried at fair value and  reported as
assets where they have a positive fair value and as liabilities  where they have
a  negative  fair  value.   Derivatives  may  be  embedded  in  other  financial
instruments. Under the new Financial Instrument standards,  derivatives embedded
in other  financial  instruments are valued as separate  derivatives  when their
economic  characteristics and risks are not clearly and closely related to those
of the host contract, the terms of the embedded derivative are the same as those
of a free  standing  derivative,  and the  combined  contract  is not  held  for
trading.  When an entity is unable to  measure  the fair  value of the  embedded
derivative separately,  the combined contract is treated as a financial asset or
liability  that is  held-for-trading  and  measured  at fair value with  changes
therein recognized in the earnings.



     The fair value of a financial instrument on initial recognition is normally
the  transaction  price,  i.e.  the  fair  value of the  consideration  given or
received.  Subsequent  to initial  recognition,  fair values are based on quoted
market prices where  available  from active  markets,  otherwise fair values are
estimated based upon market prices at reporting date for other similar assets or
liabilities with similar terms and conditions, or by discounting future payments
of interest and principal at estimated interest rates that would be available to
the Corporation at the reporting date.

     Transaction  costs are  expensed  as  incurred  for  financial  instruments
classified or designated as held-for-trading. Transaction costs related to other
financial  instruments are generally capitalized and are then amortized over the
expected  life  of  the  instrument   using  the  effective   interest   method.
Accordingly, the Deferred Charges balance of $13.5 million at December 31, 2006,
consisting  of  transaction  costs  relating to the Senior  Secured  Notes,  was
reclassified  against Long-term Debt effective January 1, 2007 under prospective
application.  For the three and six month  periods  ended  June 30,  2007,  $0.6
million and $1.3 million, respectively, of these costs were included in interest
expense under the effective interest method.

     Emerging Issues Committee  Abstract 101 ("EIC-101") states that transaction
costs  relating to line of credit and revolving debt  arrangements  are excluded
from Section 3855.  Transaction  costs of $3.4 million  relating to the new $805
million  Revolving  Credit Facility are being amortized using the  straight-line
method over the five year term of the Revolving Credit Facility.

     Hedges

     Section  3865  replaces  the guidance  formerly in Section  1650,  "Foreign
Currency  Translation" and Accounting  Guideline 13, "Hedging  Relationships" by
specifying how hedge  accounting is applied and what  disclosures  are necessary
when it is applied.  The  Corporation  does not have any derivative  instruments
that have been designated as hedges.

     Comprehensive  Income

     Section  1530  establishes  new  standards  for  reporting  the  display of
comprehensive  income,  consisting of Net Income and Other Comprehensive  Income
("OCI").  OCI is the change in equity  (net  assets) of an  enterprise  during a
reporting period from  transactions and other events from non-owner  sources and
excludes those resulting from investments by owners and distributions to owners.
The  Corporation  has no such  transactions  and events which would  require the
disclosure of OCI for the three and six month  periods ended June 30, 2007.  Any
changes  in these  items  would be  presented  in a  consolidated  statement  of
comprehensive income.

     Equity

     Section 3251 replaces Section 3250, "Surplus" and establishes standards for
the  presentation  of equity and changes in equity  during a  reporting  period,
including changes in Accumulated Other Comprehensive Income ("Accumulated OCI").
Any  cumulative  changes  in OCI would be  included  in  Accumulated  OCI and be
presented as a new category of Shareholder's  Equity on the consolidated balance
sheets.

c)   Accounting Changes

On January  1,  2007,  the  Corporation  adopted  CICA  Handbook  Section  1506,
"Accounting   Changes",   which  revises  and  replaces   former  Section  1506,
"Accounting  Changes".  The Section establishes criteria for changing accounting
policies,  together with the  accounting  treatment and disclosure of changes in
accounting policies and estimates, and correction of errors.

d)   Determining the Variability to be Considered in Applying AcG-15

On January 1, 2007, the  Corporation  prospectively  adopted the Emerging Issues
Committee issued Abstract 163,  "Determining the Variability to be Considered in
Applying  AcG-15",  which  addresses  how an  enterprise  should  determine  the
variability  to be considered  in applying  AcG-15,  "Consolidation  of Variable
Interest  Entities".  The adoption of this standard has not affected the current
or comparative period balances on the consolidated financial statements.

* Accumulated Depreciation, Depletion and Amortization

At June 30, 2007,  costs not currently  subject to  depreciation,  depletion and
amortization  included $474.8 million (June30, 2006 - $87.4 million) relating to
the  Athabasca  Oil  Sands  Project  ("AOSP")  Expansion  1 as it has  not  been
substantially completed and commercial production has not yet commenced.  During
the three and six month periods ended June 30, 2007, the Corporation capitalized
$8.1 million and $13.7 million,  respectively  (June 30, 2006 - nil) in interest

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


The  Obligations  Under  Capital  Lease  relates to the  Corporation's  share of
capital costs for the hydrogen-manufacturing  unit within the AOSP and have been
classified as a current  liability as at June 30, 2007 as the underlying  credit
facility  supporting  the capital  lease will  terminate on June 30,  2008.  The
extension of the underlying credit requires unanimous approval of the AOSP Joint
Venture  Owners.  The  Corporation  remains  the only Joint  Venture  Owner with
obligations  under the credit  facility as the other Joint  Venture  Owners have
fully repaid their respective  obligations.  The Corporation will be refinancing
its Obligations Under Capital Lease as part of its overall financing strategy.

The Operating Lease Guarantee Obligation relates to the Mobile Equipment Leases.
The  Corporation is committed to pay its 20 per cent share of an amount equal to
85 per cent of the  original  cost of the  equipment to the lessor at the end of
the  terms  of  the  leases.  Accordingly,  the  Corporation  recognized,  as  a
liability, a portion of this future payment as it relates to the service life of
the  equipment  that has passed.  During the three and six month  periods  ended
June 30, 2007, no payments were made in regard to this obligation (June 30, 2006
- - $0.4 million and $0.6 million, respectively).


Note 5. Option Premium Liability
- --------------------------------------------------------------------------------

The Corporation deferred payment and receipt of the premiums associated with the
options  described in Note 12(a) until the  settlement  of the option  contracts
between  2007 and 2009.  During the three and six month  periods  ended June 30,
2007, $5.9 million and $12.2 million,  respectively,  was paid in respect to the
settlement of the option  contracts  maturing during the period (June 30, 2006 -
nil). The remaining  total net premiums  payable by the  Corporation are US$11.0
million for the remainder of 2007,  US$32.4 million for 2008 and US$27.8 million
for 2009.



On the dates that the option  contracts  were entered  into, a net liability was
recognized on the consolidated  balance sheet at the estimated  present value of
the net  premiums  payable.  Subsequent  to the  inception  dates of the  option
contracts,  interest expense is recognized, with a corresponding increase to the
liability,  at  annual  rates  ranging  from  4.25% to 4.50%.  Interest  expense
recognized  for the three and six month  periods  ended  June 30,  2007 was $0.9
million and $1.5  million,  respectively  (June 30, 2006 - $0.9 million and $1.9
million,  respectively).  The option  premium  liability  is  denominated  in US
dollars and is translated into Canadian dollars at the period end exchange rate.
The unrealized foreign exchange gain arising on the option premium liability for
the three and six month  periods  ended June 30, 2007 was $6.4  million and $7.2
million,   respectively  (June  30,  2006  -  $3.9  million  and  $3.8  million,

The AOSP's  Upgrader has retirement  obligations  for which fair value cannot be
reasonably determined because the asset currently has an indeterminate life. The
asset  retirement  obligation  for these  assets  will be  recorded in the first
period  in which the  lives of the  assets  are  determinable.  The  Corporation
currently does not have asset  retirement  obligations  associated  with In-Situ
Projects or the Kurdistan Exploration Project as these projects are in the early
stages of development.

Note 12. Financial Instruments and Risk Management
- --------------------------------------------------------------------------------

The  Corporation's  financial  instruments that are included in the Consolidated
Balance Sheet are comprised of cash and cash equivalents,  accounts  receivable,
risk management  activities,  accounts payables and accrued liabilities,  option
premium liability and long-term borrowings.

a)   Commodity-pricing  Agreements

The Corporation has entered into various  commodity-pricing  agreements designed
to mitigate  the exposure to the  volatility  of crude oil prices in US dollars,
thereby  providing  greater  certainty  of future cash flow from the sale of the
Corporation's  synthetic crude oil products.  This risk  management  strategy is
intended to protect  the  Corporation's  base and future  capital  programs  and
ensure the funding of debt obligations.  These commodity-pricing  agreements are
accounted  for under fair value  accounting  as they did not qualify or have not
been designated as hedges for accounting purposes.

The  Corporation  has put  options at strike  prices  ranging  from  US$50.00 to
US$55.00  per barrel,  averaging  US$52.42  per barrel for the three year period
beginning  January 1, 2007.  The  premiums  for the  purchased  put options were
partially  offset through the sale of call options at strike prices ranging from
US$90.00 to US$95.00  per barrel,  averaging  US$92.41  per barrel for the three
year period  beginning  January 1, 2007,  resulting in a net premium  liability.
Payment of the net premium  liability is deferred  until the  settlement  of the
option contracts between 2007 and 2009.




As at June 30, 2007,  the  Corporation  had the  following  put and call options
outstanding:


                                                             2007             2008              2009

   Average Call Strike Price                               US$92.50         US$94.25          US$90.50
=======================================================================================================


The fair  value of the  option  contracts  was  recognized  on the  consolidated
balance sheet on the dates they were entered into. The  counterparties  to these
put and call options have  investment  grade credit ratings,  thereby  partially
mitigating the credit risk  associated  with these  financial  instruments.  The
following  table  presents  the  reconciliation  of the  Risk  Management  Asset
(Liability):

b)   Fair  Values  of  Financial  Assets  and  Liabilities

The fair values of financial  instruments  that are included in the Consolidated
Balance  Sheets,  other than long-term  borrowings,  approximate  their carrying
amount due to the  relatively  short period to maturity of these  instruments or
have interest rates that approximate their fair value.
