WESTERN OIL SANDS

INTERIM REPORT FOR THE THREE-MONTH PERIOD ENDED MARCH 31, 2006


MESSAGE TO SHAREHOLDERS

Western Oil Sands Inc. ("Western")  announced today its financial and operating
results for the first quarter of 2006.  Western generated net revenue of $139.2
million,  EBITDAX  of $62.1  million  and cash  flow from  operations  of $47.8
million  ($0.30 per share) and a net loss of $21.6 million ($0.13 per share) in
the first quarter of 2006. By comparison, in the first quarter of 2005, Western
generated net revenue of $91.7 million, EBITDAX of $27.4million, cash flow from
operations  of $10.8  million  ($0.07 per share) and a net loss of $1.9 million
($0.01 per share).  In the first quarter of 2006,  our net loss included  $68.3
million in unrealized  foreign  exchange and unrealized risk management  losses
($45.2 million net of tax) compared to an unrealized  foreign  exchange loss of
$2.7 million ($2.2 million net of tax) for the first quarter of 2005. Excluding
the impact of risk management and foreign  exchange losses each net of tax, net
earnings  for the first  quarter of 2006 would  have  equated to $23.6  million
compared to net earnings of $0.3 million for the prior year period.

     Western's  financial  performance  during  the first  quarter  of 2006 was
positively  impacted  by a 27 per  cent  increase  in West  Texas  Intermediate
("WTI") prices and the absence of production  volumes  subject to  fixed-priced
swap  contracts.  However,  wider  light to heavy  crude oil  differentials,  a
strengthening  Canadian  dollar relative to the US dollar compared to the first
quarter of 2005, and a production  interruption  associated with repairs to the
conveyor belt at the Mine had an adverse impact on our results.

HIGHLIGHTS

o    During the first quarter of 2006,  production  averaged 25,945 barrels per
day net to Western  compared  to 26,503  barrels  per day net to Western in the
first quarter of 2005.  Production  for the quarter was lower than  anticipated
due to an unplanned  slowdown at the Mine resulting from a longitudinal tear in
the conveyor belt that transports  bitumen ore from the primary crushers at the
Mine to the Extraction Plant. Through the dedicated efforts of personnel at the
Mine, the Project  operated at  approximately  one-third of stated design rates
while the  replacement  belt was prepared for  installation.  The  installation
itself was flawlessly  executed and completed ahead of schedule with production
interruptions  limited to 22 days starting from February 24th.  Full production
resumed  earlier than  anticipated  and  subsequent to this repair,  rates have
exceeded stated design rate capacity averaging approximately 34,000 barrels per
day net to Western from the date of return to full operations to the end of the
quarter.

o    Western  announced a significant  increase in its undeveloped land base as
part of its  year-end  disclosure.  Over the course of the last year,  the land
position held by Joint Venture Participants has increased to over 280,000



acres, of which 71 per cent represents mineable leases. As a result, Western's
rights with respect to its net undeveloped  land acreage has more than doubled
to 60,000 acres.

o    As previously disclosed, Western purchased Lease 353 during 2005 which may
be conducive to in-situ  development.  This lease  acquisition  directly aligns
with our long-term growth strategy to capture large hydrocarbon  resources with
long-life  potential and  complements  our existing asset base. It is estimated
that  over 80 per cent of the oil sands  resource  in the  Athabasca  region is
in-situ and Western's lease  acquisition  represents the initial step of a more
comprehensive  in-situ  program.  Over the past  year,  we have  augmented  our
technical  team  and  expanded  our  core  competencies  to take  advantage  of
opportunities  such as this, and this team has been  instrumental in developing
our long-term in-situ participation and technical development strategy.

o    As an entrepreneurial growth-oriented company focused on shareholder value
creation,  Western's strategy includes  opportunistically  growing our business
and  leveraging  our strengths by taking our core  competencies  and skills and
applying  them to new business  opportunities.  In this regard,  we continue to
identify and evaluate new business  opportunities  related to large,  long-life
resource capture and technology  development.  In addition,  in response to the
wider light to heavy crude oil differentials currently being experienced in the
market,  Western is independently  evaluating  different forms of upgrading and
refining in order to reduce the impact of heavy oil differentials. Moreover, we
continue  to evaluate  various  downstream  initiatives  which vary in size and
scope, all of which are focused on the further upgrading of heavy oil products.
As a  matter  of  policy,  Western  does  not  discuss  any  specific  business
opportunity  until  such  time  as  it  has  been  fully   considered,   it  is
contractually secured or it is material to Western.

MANAGEMENT'S DISCUSSION AND ANALYSIS

The following  discussion of financial  condition and results of operations was
prepared  as of April  26,  2006 and  should  be read in  conjunction  with the
Interim Unaudited Consolidated Financial Statements for the periods ended March
31, 2006 and 2005 and the Audited Consolidated Financial Statements at December
31, 2005 included in the Annual Report. It offers Management's  analysis of our
financial and operating results and contains certain forward-looking statements
relating but not limited to our operations,  anticipated financial performance,
business  prospects  and  strategies.   Forward-looking  information  typically
contains  statements  with words such as  "anticipate",  "estimate",  "expect",
"potential",  "could", or similar words suggesting future outcomes.  We caution
readers and  prospective  investors of the  Company's  securities  to not place
undue reliance on forward-looking  information as by its nature, it is based on
current  expectations   regarding  future  events  that  involve  a  number  of
assumptions, inherent risks and uncertainties, which could cause actual results
to differ  materially from those  anticipated by Western.  These risks include,
but are not limited to, risks of commodity  prices in the marketplace for crude
oil and natural  gas;  risks  associated  with the  extraction,  treatment  and
upgrading  of mineable  oil sands  deposits;  risks  surrounding  the level and
timing of  capital  expenditures  required  to  fulfill  the  Project's  growth
strategy;   risks  of  financing  these  growth   initiatives  at  commercially
attractive levels; risks of being unable to



participate in expansion and  corresponding  loss of voting rights in the AOSP;
risks relating to the execution of the Project's optimization  strategy;  risks
involving  the  uncertainty  of estimates  involved in the reserve and resource
estimation  process  and ore body  configuration/geometry,  uncertainty  in the
assessment of asset  retirement  obligations,  uncertainty in the estimation of
future  income  taxes,  and  uncertainty  in  treatment  of capital for royalty
purposes;  risks surrounding health, safety and environmental  matters; risk of
foreign exchange rate  fluctuations;  risks and  uncertainties  associated with
securing the necessary  regulatory approvals for expansion  initiatives;  risks
surrounding major  interruptions in operational  performance  together with any
associated   insurance   proceedings   thereto;   and  risks   associated  with
identifying,   negotiating  and  completing  our  other  business   development
activities,  both those that relate to oil sands  activities  and those that do
not, either domestically or abroad.

OPERATING RESULTS

Production

During  the  first quarter of 2006, Western's  net  bitumen production averaged



25,945  barrels per day compared to 26,503 barrels per day in the first quarter
of 2005.  Unplanned  operational  outages impacted production in both the first
quarter of 2006 and 2005.  First  quarter  2006  production  was  predominantly
impacted by the unplanned  outage and  subsequent  replacement  of the conveyor
belt at the Mine which transports  bitumen ore from the primary crushers to the
Extraction Plant. In the first quarter of 2005,  production was interrupted due
to completion of repairs stemming from unplanned outages at the Upgrader in the
fourth  quarter of 2004.  During the second  quarter of 2006, the Athabasca Oil
Sands Project  ("AOSP") is undertaking a full planned  turnaround of the entire
Project.  Considerable  care and planning  has been  directed to this effort to
ensure an expeditious return to full production in mid-2006.  It is anticipated
the turnaround  activities will span an eight-week time period, where a portion
of this schedule will be associated  with an operational  slowdown prior to the
shutdown and a subsequent ramp-up period to full production.

     (Q1-2005 - nil) has been incurred for transportation  costs related to Oil
     Sands.


Revenue

Western recorded crude oil sales revenue of $207.8 million in the first quarter
of 2006,  including  $185.4  million from the sale of  proprietary  production,
compared  to  $166.1   million  in  the  first   quarter  of  2005,   including
$120.3million  from the sale of  proprietary  production.  This  year-over-year
increase is largely the result of a higher  realized  selling  price per barrel
due to higher  underlying  WTI prices,  combined with the absence of production
volumes  subject  to fixed  price  swap  contracts  compared  to the prior year
period,  partially offset by a strengthening of the Canadian dollar relative to
the US dollar and wider heavy crude oil differentials.  Should crude oil prices
maintain their present levels,  Western anticipates  materially higher realized
crude sales prices over the remainder of fiscal 2006 relative to the comparable
prior year period as a result of the expiry of the fixed price hedging  program
on December 31, 2005. Western does not have any 2006 production volumes subject
to risk management activities at the present time.

     Oil sands sales volumes,  which include bitumen and purchased  feedstocks,
averaged 37,188 barrels per day in the first quarter of 2006 compared to



34,488 barrels per day in the first quarter of 2005. Sales volumes in the first
quarter of 2006 were approximately 10 per cent higher compared to first quarter
of 2005 and were adversely  impacted by an unplanned  repair and replacement of
the conveyer belt at the Mine,  resulting in reduced  saleable  product volumes
ultimately produced from the Upgrader.

     The first  quarter of 2006 was  characterized  by  continued  strength  in
commodity prices with WTI averaging  US$63.48 per barrel for the quarter, a six
per cent  increase  over the fourth  quarter of 2005 and a 27 per cent increase
compared to the prior year period. Western's realized price increased to $55.31
per barrel in the first  quarter of 2006 as  compared  to $38.76 per barrel the
prior year period. Sales price realizations  increased by $4.66 per barrel from
the  fourth  quarter  of 2005.  During  these  same  time  periods,  heavy  oil
differentials,  which are correlated to the price of WTI,  widened.  With heavy
oil products in the overall sales mix, absolute  commodity prices and heavy oil
market  differentials  affect average  synthetic crude oil price  realizations.
Western's  price  differential  widened  compared to the prior year period as a
result of broader market forces which caused heavy oil  differentials  to widen
to 46 per cent of WTI  compared  to 40 per cent of WTI in the first  quarter of
2005 or, in absolute  dollar  terms,  approximately  US$29.00 per barrel in the
first  quarter of 2006  compared to  approximately  US$20.00  per barrel in the
prior  year  period.  This  represents  a 47 per cent  increase  in the last 12
months.  This was  partially  offset  by  marginally  lower  heavy  volumes  in
percentage  terms in the overall sales mix.  Subsequent to the end of the first
quarter, the light to heavy differential  narrowed  considerably as a result of
several factors, the most significant of which include: seasonal asphalt demand
causing refiners to process additional volumes of available heavy crude oil and
the opening of new  incremental  markets for Canadian  heavy crude oil into the
United States.

     Western  generated  net revenue of $139.2  million in the first quarter of
2006, after considering the impact of purchased  feedstocks and  transportation
costs downstream of Edmonton.  By comparison,  net revenue of $91.7 million was
recorded  in the first  quarter  of 2005.  Feedstocks  are  crude oil  products
introduced    at   the    Upgrader.    Some    are    introduced    into    the
hydrocracking/hydrotreating  process and some are used to create various blends
of synthetic crude oil products.  The cost of these feedstocks depends on world
oil markets and the spread between heavy and light crude oil prices.

Operating Costs

Western's  unit cash operating  costs were $26.12 per processed  barrel for the
first quarter of 2006 compared to $25.44  (restated)  per processed  barrel for
the first  quarter  of 2005 and  $23.44  per  processed  barrel  for the fourth
quarter of 2005.  Compared  to the first  quarter  of 2005,  this  increase  is
largely  attributable to operational  outages  predominantly  stemming from the
conveyor belt repair at the Mine during the first  quarter.  As the majority of
our  operating  costs are fixed in nature,  lower than  anticipated  production
results in a higher unit operating cost as fixed costs are allocated over fewer
barrels. Higher operating costs compared to the same time period last year also
reflect higher natural gas costs.

     Compared to the fourth  quarter of 2005,  unit operating  costs  increased
$2.68 per  processed  barrel in the first  quarter of 2006.  This  increase was
largely due to decreased  bitumen  production  during the first quarter of 2006
which  occurred  as a result of the  unplanned  repair and  replacement  of the
conveyor belt,  somewhat  offset by reduced natural gas costs during the repair
period.

(1)  Operating  Expenses Per  Processed  Barrel  ($/bbl) is calculated as Total
     Operating  Expenses  For Bitumen  Sold  divided by  Synthetic  Crude Sales
     Excluding Blend Stocks.
(2)  Amount  restated  to reflect $45  thousand  reclassified  to Research  and
     Business Development previously accounted for as operating expenses.

     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  blend  stocks,  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 $0.6 million in the first quarter of 2006 remained  unchanged from
the first quarter of 2005. Year-over-year amounts are consistent as a result of
higher deemed  bitumen  royalty  prices,  offset by lower  production  volumes.
Compared to the fourth quarter of 2005, royalties decreased $0.4 million in the
first quarter of 2006, primarily the result of a decrease in production volumes
partially offset by higher deemed bitumen prices.

CORPORATE RESULTS

Research and Business Development Expense

Western incurred $6.0 million in research and business  development expenses in
the  first  quarter  of 2006,  $3.8million  of which  relates  specifically  to
AOSP-related research and development  projects.  This compares to $0.7 million
recorded for research and business development expenses in the first quarter of
2005. The increase is the result of additional efforts in research and business
development.

General and Administrative Expense

General and  administrative  expenses  ("G&A")  were $3.9 million for the first
quarter of 2006  compared to $1.9  million  (restated  to reflect  $0.7 million
reclassified  to Research and Business  Development)  for the first  quarter of
2005. This increase is due to the increased number of employees within Western,
together with additional consulting costs for various corporate initiatives.

Insurance Expense

Insurance  expenses were $2.7 million for the first quarter of 2006 compared to
$1.9  million in the first  quarter of 2005.  Insurance  expenses  were  higher
compared to the prior year period due to additional  premiums  associated  with
increased levels of coverage, partially offset by the strengthening of the



Canadian  dollar  as the  premiums  are paid in US  dollars  but  reported  for
financial statement purposes in Canadian dollars.

Interest Expense

Interest expense totaled $13.0 million in the first quarter of 2006 compared to
$15.1 million in the first quarter of 2005. First quarter 2006 interest expense
is comprised of $11.3 million related to interest  charges on debt  obligations
(Q1-2005 - $14.5  million),  $0.7 million  (Q1-2005 - $0.5  million) on capital
lease  obligations  and $1.0  million  (Q1-2005  - nil) on the  option  premium
liability.  The option premium liability  relates to Western's  strategic crude
oil risk management  program  implemented in the third quarter of 2005, and the
decision  to defer  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 14 per cent decrease in total interest  expense  compared to the first
quarter of 2005 is  largely  the result of the  Canadian  dollar  strengthening
against the US dollar  during this  period  compared to the prior year  period,
thereby  reducing  interest  charges  on our US  denominated  Notes  which  are
reported in Canadian  dollars,  and the significant  reduction in the Revolving
Credit Facility over the comparable period.  Interest expense decreased by $0.8
million in the first quarter of 2006 compared to the fourth quarter of 2005 due
to a further  decrease in the balance drawn on the Revolving  Credit  Facility,
together with lower negotiated interest rates on the Revolving Credit Facility,
partially  offset by a marginal  weakening  of the Canadian  dollar  during the
first quarter against the US dollar.

Depreciation, Depletion and Amortization

Depreciation, depletion and amortization ("DD&A") totaled $10.5 million for the
first  quarter  of 2006  and was  equivalent  to the  first  quarter  of  2005.
Year-over-year  amounts are  comparable due to similar  production  levels over
both time  periods,  together  with  reasonably  similar  reserve bases used in
calculating the unit of depletion.

Foreign Exchange

During the first quarter of 2006,  Western  reported a foreign exchange loss of
$0.4 million  compared to a loss of $2.9 million in the first  quarter of 2005.
This loss is as a result  of the  marginal  weakening  of the  Canadian  dollar
against the US dollar  compared to the previous  quarter's  month-end  noon-day
rate.  Western's  long-term notes and option premium liability are converted at
the month-end  noon-day rate. As reference points, the noon-day closing foreign
exchange rate on March 31, 2006 was $0.8568  US/Cdn  compared to $0.8577 US/Cdn
on December 31, 2005 and $0.7631 US/Cdn on March 31, 2005. The average rate for
the first quarter of 2006 was $0.8659 US/Cdn compared to $0.8155 US/Cdn for the
prior year period and $0.8524 US/Cdn for the fourth quarter of 2005.

Risk Management Activities

Western's  initial  fixed price hedging  program  expired on December 31, 2005.
Western has no risk management  activities  associated with fiscal 2006 and, as
such,  crude  oil price  realizations  in the  first  quarter  of 2006 were not
impacted by risk  management  activities.  Realizations in the first quarter of
2005 were  negatively  impacted  by $11.85 per  barrel  due to risk  management
activities.

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


     In the third  quarter of 2005,  Western  implemented  strategic  crude oil
hedges in order to provide greater cash flow certainty during those years where
significant AOSP expansion capital expenditures are expected.  Western employed
a collar  strategy  whereby a series of put and call options were purchased and
sold with a number of major financial  institutions.  The program established a
weighted  average  floor  price of  US$52.42  on 20,000  barrels  per day and a
ceiling price of US$92.41 on an average  13,333  barrels per day for the period
January 2007 through to December2009.

     Western is not utilizing  hedge  accounting  treatment under Canadian GAAP
for this program and, as a result, certain mark-to-market adjustments will 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 period ended March 31, 2006,  Western's  risk
management assets decreased  significantly in value from the amount recorded as
at December  31,  2005,  resulting in a  mark-to-market  loss of $67.7  million
($44.7 million net of tax) primarily due to the  significant  strengthening  in
WTI prices during the quarter.  This loss does not impact stated cash flow from
operations.

Income Taxes

For the first  quarter of 2006,  Western  had an income tax  recovery  of $9.9
million  compared to an expense of $0.06million for the same period last year.
This reflects the tax recovery largely generated from the risk management loss
partially  reduced by the future income tax expense from  Western's  other net
earnings.

Net Loss

During the first quarter of 2006,  Western reported a net loss of $21.6 million
($0.13 per share)  compared to a net loss of $1.9 million  ($0.01 per share) in
the first  quarter of 2005.  The net loss in the first quarter of 2006 includes
the  impact of $67.7  million  ($44.7  million  net of tax) in risk  management
losses,  in  addition  to $0.6  million  ($0.5million  net of  tax) in  foreign
exchange losses on our US dollar denominated debt and option premium liability.

     EBITDAX  (Earnings  before  Interest,  Taxes,   Depreciation,   Depletion,
Amortization,   Stock-based   Compensation,   Accretion  on  Asset   Retirement
Obligation,  Foreign  Exchange and Risk  Management)  was $62.1 million for the
first  quarter  of 2006,  reflecting  a 127 per cent  increase  over the  $27.4
million  recorded  for the first  quarter of 2005.  First  quarter 2006 EBITDAX
decreased $22.4 million compared to the fourth quarter of 2005. The improvement
in EBITDAX from the previous year's comparative quarter is mainly the result of
the increase in the average  synthetic  crude oil sales price due to higher WTI
prices and the  absence  of fixed  priced  swaps,  offset by  one-time  charges
associated  with the  repairs to address  the  operational  issues  encountered
during the first quarter, along with higher variable costs which are correlated
to higher  WTI  prices.  The  decrease  in  EBITDAX  from the prior  quarter is
primarily the result of lower than anticipated production,  partially offset by
higher  realized sales prices and the expiry of the fixed price hedging program
in December 2005.

     Cash flow from  operations  before  changes in  non-cash  working  capital
("cash flow from  operations")  was  $47.8million for the first quarter of 2006
compared to $10.8 million in the first quarter of 2005. First quarter 2006 cash
flow from  operations  decreased $22.6 million over the fourth quarter of 2005.
This decrease is the result of lower bitumen production, partially offset by an
increase in the average synthetic crude oil sales price.

FINANCIAL POSITION

Bank Debt

During  the first  quarter  of 2006,  Western  repaid  $41  million on its $340
million Revolving Credit Facility (the "Revolving  Credit  Facility")  bringing
the amount outstanding to nil as a result of positive cash flow from operations
during the quarter.

     Western  has  previously  communicated  that  the  total  capacity  of the
Revolving  Credit  Facility  was  limited  to  $299million   based  on  certain
covenants.  This  ceiling is a function of the before tax net present  value of
Western's share of the proved  reserves  associated with the Project based on a
constant price  discounted at 10 per cent. As a result of Western's most recent
independent appraisal of the value associated with our proved reserves, we have
access to the full $340 million  capacity under the Revolving  Credit Facility.
Western's debt to total capitalization as at March 31, 2006 equaled 49 per cent
compared to 60 per cent as at March 31, 2005.



Capital Expenditures

Western's  capital  expenditures  totaled $35.3 million in the first quarter of
2006  compared  to  $17.6  million  in  the  first  quarter  of  2005.  Capital
expenditures in the first quarter of 2006 included $10.9 million for production
optimization  programs and AOSP project  capital,  $3.2 million for  sustaining
capital,  $19.2 million for  expansion  related  capital,  $0.8 million for new
business development and $1.2 million for other corporate expenditures.

Analysis of Cash Resources

Cash balances  totaled $15.7 million at March 31, 2006 compared to $5.7 million
at March 31, 2005.  During the quarter,  Western repaid the entire  outstanding
balance under its Revolving Credit Facility and, as a result,  excess free cash
flow will be accumulated  on the balance sheet to fund the upcoming  turnaround
in the short term. Longer term, excess free cash flow will be applied to future
capital  commitments  relating  to the  first  expansion  phase.  Cash  inflows
included:  $47.8 million in cash flow from operations and $2.6 million from the
exercise of employee  stock  options and a $36.5  million  increase in non-cash
working capital. Cash outflows included: capital expenditures of $35.3 million,
long-term debt  repayment of $41.0 million and repayment of  obligations  under
capital lease and deferred charges of $0.3 million.

     During the first quarter of 2006, the increase in non-cash working capital
was the result of a $25.7  million  decrease  in accounts  receivable,  a $21.0
million  increase in accounts  payable and a $0.7  million  decrease in prepaid
expenses,  offset by a $10.9  million  increase in  inventory.  The decrease in
accounts  receivable is the result of decreased sales volumes stemming from the
unplanned outage during the quarter.  The increase in accounts payable reflects
an additional  three months of accrued  interest on the US denominated debt and
increased  accruals related to both oil sands and marketing  feedstocks  costs.
Inventory is higher as a result of  additional  barrels of finished  product in
inventory, together with higher production costs associated with these barrels.

Insurance Claims

There were no new developments during the first quarter of 2006 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 during 2007.

Flow-Through Shares

Related  to the  issuance  of  flow-through  shares in 2001 and  2002,  Western
renounced  Canadian  exploration  expenses  in the  aggregate  amount  of $29.2
million and $19.5  million,  respectively.  Under the  mechanics of  renouncing
qualifying   expenditures   pursuant   to   flow-through   shares,   individual
shareholders  can  reduce  their  income  subject  to  personal  income  taxes.
Commencing  in the latter part of the year,  discussions  were held between the
AOSP  and  the   Canada   Revenue   Agency   ("CRA")   regarding   the   proper
characterization of certain  expenditures  included in the Canadian exploration
expenses  in those  years.  If the CRA  successfully  asserts  a change  in the
characterization  of  these  expenditures,   any  resulting  reduction  in  the
renunciations could impact Western's obligations under the indemnity provisions
in the  subscription  agreements and, in turn, will impact  Western's  reported
results.  The  subscription  agreements for such flow through shares  stipulate
that Western has indemnified subscribers for an amount equal to the tax payable
and any  associated  interest  by the  subscribers  if such  renunciations  are
reduced under the Income Tax Act (Canada).



OUTLOOK FOR THE REMAINDER OF 2006

As evidenced  by record  production  levels set during 2005 and rates  achieved
following the  replacement of the conveyer belt, the AOSP is already seeing the
benefits of numerous  production  optimization  initiatives  completed to date.
Over the  course  of  2006,  Western  will  continue  to  allocate  capital  to
production  optimization  initiatives  as the Project works  towards  achieving
reliable and sustainable production volumes.

     The AOSP will undertake its first full plant turnaround  during the second
quarter of 2006.  It is  anticipated  that  production  will quickly  return to
levels  achieved  leading up to the  turnaround  which  were well above  stated
design  rates.  In addition,  we look forward to  potentially  benefiting  from
additional  production  optimization  resulting from the full plant turnaround.
Consequently,  Western is  maintaining  its  production  guidance  of 29,000 to
30,000 barrels per day for 2006.

AOSP Expansion Update

The AOSP continues to make solid progress on the first expansion  phase. We are
moving  methodically  towards completing the third and final gate of the gating
process,  the culmination of which will be a final  investment  decision.  This
final gate more  narrowly  defines the scope of the  expansion,  in addition to
estimating  the  capital  cost to a higher  degree of  certainty.  In the third
quarter of 2006, it is anticipated  that Western will seek final Board approval
of the first  expansion  phase and,  at that time,  we will be in a position to
book additional reserves associated with the east side of Lease13.

Resources

Western recently  outlined the total land base in the Athabasca region in which
we have rights to  participate.  This land  position  represents  acreage  with
unevaluated  land,  resources  and  reserves.  As Western  moves  closer to the
extraction of bitumen resources on the various leases,  further delineation and
classification  of the  recoverable  barrels  will  ensue.  Western's  right to
participate  in the mineable oil sands leases held by Shell (namely  leases 13,
90,  88, 89 and 9), and  excluding  those  acquired  in 2005,  has not  changed
materially in total;  however,  the barrels associated with specific leases has
been adjusted to reflect  certain  property  swaps to ensure a contiguous  land
position in order to  facilitate  a viable  mining plan.  Additional  core hole
drilling to further understand the quality and extent of the ore and changes in
evaluation  processes and procedures used to define in-place resources has also
provided a refinement of the resource potential.

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 2005 Annual Report and
Annual Information Form, which are available on the Company's website.

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.

* Accumulated Depreciation, Depletion and Amortization

At March 31, 2006, the Producing Assets in the Athabasca Oil Sands Project (the
"AOSP") include asset  retirement  costs of $7.1 million ($7.0 million - 2005).
Costs not currently subject to depreciation, depletion and amortization include
$62.6 million  relating to the AOSP and $16.3 million relating to Corporate and
Other,  as the  projects  associated  with these  costs were not  substantially
complete  and there has been no  commercial  production  associated  with these
projects.


2. LONG-TERM DEBT

                                                       March 31,   December 31,

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


The Corporation's US dollar  denominated Senior Secured Notes (the "Notes") are
translated  into  Canadian  dollars  at  the  period  end  exchange  rate.  The
unrealized  foreign  exchange  gain  arising  on the Notes for the three  month
period  ended March 31, 2006 was $0.5  million  (March 31, 2005 - $2.7  million
unrealized foreign exchange loss). As at March 31, 2006, a total of $183.7



million of  unrealized  foreign  exchange  gains had been  recognized  from the
inception of the Notes, approximately $92 million of which has been capitalized
as the unrealized gains were recognized prior to commercial operations.

     Under the terms of the Notes, there is a limit on the amount available for
drawdown  on the  Revolving  Credit  Facility.  This limit is  determined  as a
function of the net  present  value of future cash flows  before  income  taxes
discounted at 10 per cent from the Corporation's  proved reserves determined on
a constant pricing basis by the independent reserve evaluators.  As a result of
the  reserves  evaluation,  the  amount  available  for  drawdown  for  general
corporate purposes increased from $299 million to the full $340 million limit.

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

The capital  lease  obligation  relates to the  Corporation's  share of capital
costs for the  hydrogen-manufacturing  unit within the AOSP.  Repayments of the
principal  obligation  are $1.3 million per year and are scheduled to remain at
that level until repaid.

     Under the  Operating  Lease  for  Mobile  Equipment,  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
lease.  Accordingly,  the Corporation recognizes,  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 month period ended March 31,  2006,  the  Corporation
paid  $0.2  million,  in  regard  to this  obligation  (March  31,  2005 - $1.4
million).


4. OPTION PREMIUM LIABILITY

The Corporation  deferred  payment and receipt of the premiums  associated with
the  options  described  in Note  12(b)  until  the  settlement  of the  option
contracts  between  2007 and  2009.  The  total  net  premiums  payable  by the
Corporation are US$21.9 million for 2007,  US$32.4 million for 2008 and US$27.8
million for 2009. On the dates that the option  contracts  were entered,  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%. During
the three month period ended March 31, 2006,  $1.0 million of interest  expense
was  recognized  (March  31,  2005 - nil).  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 loss arising on the option
premium  liability  for the three  months ended March 31, 2006 was $0.1 million
(March 31, 2005 - nil).

     The following table presents the  reconciliation of the net Option Premium
Liability:

7. NET EARNINGS PER SHARE

The basic and diluted  weighted  average  number of common shares  outstanding,
both  current  and prior  period,  reflect a  three-for-one  stock split of the
Corporation's  common shares on May 30, 2005. The basic weighted average number
of common shares for the three month period ended March 31, 2006 is 160,568,322
(March 31, 2005 - 159,958,482).  Due to a loss for the three month period ended
March 31, 2006 and 2005,  no  incremental  shares were included for the diluted
earnings  per  share  weighted  average  number  because  the  effect  would be
anti-dilutive.

exercise  price of $33.62  (March  31,  2005 - 191,670  options  at an  average
exercise  price of $19.78).  The fair values of all options  granted during the
period  are   estimated   as  at  the  grant   date  using  the   Black-Scholes
option-pricing  model.  The Corporation  uses sources such as Bloomberg L.P. to
determine certain assumptions.  The weighted-average fair values of the options

outstanding at March 31, 2006 (March 31, 2005 - nil).



(d) Stock-Based Compensation

For the three month  period ended March 31, 2006,  the  Corporation  recognized
$1.8 million (March 31, 2005 - $0.6million) in compensation  expense related to
stock-based compensation issued subsequent to January 1, 2003. The compensation
expense is comprised of $0.8 million (March 31, 2005 - $0.2 million) in respect
to the Corporation's  stock option plan and $1.0 million (March 31, 2005 - $0.4
million) in respect to the  Corporation's  Performance  Share Unit Plan.  Under
CICA 3870,  no  compensation  expense is  required to be  recognized  for stock
options granted before January1, 2003. Had compensation expense been determined
based on the fair value method for awards granted on or after December 31, 2001
but before January 1, 2003, the Corporation's net earnings and net earnings per
share would have been adjusted to the proforma amounts indicated below:

11. COMMITMENTS AND CONTINGENCIES

(i) Insurance Claims

The Corporation  has various  outstanding  claims under the insurance  coverage
provided in its Joint Venture  construction  policies.  These claims  include a
loss of profits  claim  stemming  from the fire at the  Muskeg  River Mine (the
"Mine") on January 6, 2003,  commonly  referred  to as Section  III; a physical
property  damage  claim  stemming  from the  same  fire at the  Mine,  commonly
referred to as Section I; and a cost overrun and project delay claim,  commonly
referred to as Section IV.  During the year ended  December 31, 2005,  the AOSP
reached a  settlement  in  respect of the  insurance  coverage  provided  under
Section III. The Corporation  received $19.4 million as part of this settlement
and has also  finalized the terms of a contingent  settlement for its remaining
share of the  settlement  proceeds  in the amount of $24.6  million  from those
insurance  underwriters that also subscribed to the Section IV. The Corporation
had previously received $16.1 million in respect to the coverage provided under
Section I.  However,  those  insurance  underwriters  that were involved in the
Section IV claim again  withheld  their portion of the Section I claim totaling
$19.4 million. The remaining settlement that has not been received under either
Section I or III would become  payable to the  Corporation in the event that it
is successful in the arbitration proceedings that are presently ongoing against
these Section IV insurance underwriters.  Arbitration proceedings under Section
IV of the Policy have been  initiated  to resolve the  disputes  with  insurers
surrounding this claim for payment.  Following these arbitration hearings,  the
Corporation  would  expect to  receive a binding  decision  from the panel with
respect to the claim.  In order to preserve  its rights  under the Policy,  the
Corporation filed a Statement of Claim in the Court of Queen's Bench of Alberta
against the defendant insurance  underwriters and the broker for the full limit
of the Policy, namely $200 million, and is also seeking interest and aggravated
and punitive damages.

     The  related  settlements  of both  Section  I and  Section  III have been
credited to property, plant and equipment, as these claims relate to costs that
were  capitalized in association  with repairing the assets damaged by the fire
or those capitalized prior to the commercial operations.

     No amounts,  other than those  collected at December  31, 2005,  have been
recognized  in these  statements  relating to  insurance  policies  nor will an
amount be recognized until the proceeds are received.

(ii) Flow-Through Shares

In connection  with the issuance of flow through  shares in 2001 and 2002,  the
Corporation  renounced Canadian exploration expenses in the aggregate amount of
$29.2 million and $19.5 million, respectively. Under the subscription



agreements  for  such  flow-through  shares,  the  Corporation  has  agreed  to
indemnify subscribers for an amount equal to the tax payable and any associated
interest by the subscribers if such  renunciations are reduced under the Income
Tax Act (Canada).  Discussions  between the AOSP and the Canada  Revenue Agency
("CRA") are ongoing  with  respect to the proper  characterizations  of certain
expenditures  included in the Canadian  exploration expenses in those years. If
the  CRA  successfully  asserts  a  change  in the  characterization  of  these
expenditures,  any resulting  reduction in the  renunciations  could impact the
Corporation's  obligations under the indemnity provisions in these subscription
agreements.

(iii) Other

The Corporation,  in association with its 20 per cent ownership of the AOSP, is
a joint  defendant and plaintiff in a number of legal actions that arise in the
normal course of business.  The Corporation  believes that any liabilities that
might arise  pertaining to such matters would not have a material effect on its
consolidated financial position.


12. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

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.  Certain of these  commodity-pricing
agreements were accounted for as hedges, as they qualified for hedge accounting
under  Accounting  Guideline  13 and were  designated  as hedges,  while  other
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.

(a) Hedge Accounting

There were no crude swap positions in place during the three months ended March
31,  2006 as the crude oil swaps were  completed  in 2005.  For the three month
period ended March 31, 2005, the  Corporation's  revenues were reduced by $36.8
million from crude oil price hedging losses.

(b) Fair Value Accounting

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 March 31, 2006, the Corporation
had outstanding the following put and call options:



                                             2007         2008         2009

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

     The fair value of the option  contracts was recognized on the consolidated
balance  sheet on the dates they were  entered  into.  During  the three  month
period ended March 31, 2006, the  Corporation  recognized an unrealized loss of
$67.7million (March 31, 2005 - nil) on the Risk Management Asset, marking it to
the fair value at the end of the period.  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:
