WESTERN OIL SANDS 2007 INTERIM REPORT
for the three-month period ended March 31

TO OUR SHAREHOLDERS
===============================================================================

Western Oil Sands Inc.  (OWesternO)  generated  net revenue of $179.2  million,
EBITDAX of $81.1 million, cash flow from operations of $63.0 million ($0.39 per
share) and net earnings of $31.6 million ($0.20 per share) in the first quarter
of 2007.  By  comparison,  in the first  quarter of 2006 Western  generated net
revenue of $139.2 million,  EBITDAX of $62.1 million, cash flow from operations
of $47.8 million  ($0.30 per share) and a net loss of $24.8 million  (restated)
($0.15 per share).  In the first quarter of 2007,  net earnings  included $12.8
million ($11.0 million net of tax) in net unrealized  foreign exchange and risk
management  (mark-to-market) losses compared to net unrealized foreign exchange
and risk management (mark-to-market) losses of $68.3 million ($45.2 million net
of tax) for the first quarter of 2006.

     Production  during the first quarter of 2007 averaged  32,325  barrels per
day  compared  to  25,945  barrels  per  day  in the  first  quarter  of  2006,
representing  a 25  per  cent  increase  and  the  best  first  quarter  winter
performance  ever for the  Athabasca  Oil  Sands  Project  (OAOSPO).  Western's
financial  performance during the first quarter of 2007 was positively impacted
by this increase  together with a  significant  (29 per cent)  narrowing of the
light to heavy crude oil  differential and a weaker Canadian dollar relative to
the US dollar  compared to the prior year period.  These positive  developments
were partially offset by an eight per cent decrease in West Texas  Intermediate
(OWTIO) prices.


HIGHLIGHTS

o    Western  announced  future growth plans for the AOSP with proposed  permit
     applications for Expansions3  through 5 of the Project.  These plans would
     facilitate  mineable bitumen  production to approximately  770,000 barrels
     per day,  or  154,000  barrels  per day net to  Western.  These  plans are
     consistent with Western's  stated long term objective of growing its total
     oil sands  production to in excess of 200,000 barrels per day. Western now
     believes this production target is attainable through current  operations,
     Expansion  1 through  5 and  in-situ  volumes.  Western  continues  to see
     potential for mining  expansions  beyond Expansion 5 based on the resource
     potential of the unevaluated leases associated with the AOSP.




o    WesternZagros  Limited  (OWesternZagrosO),  a  wholly-owned  subsidiary of
     Western  confirmed that its Exploration and Production  Sharing  Agreement
     (OEPSAO) was ratified by the  Kurdistan  Regional  Government  (OKRGO) and
     confirmed by His  Excellency  Nerchivan  Barzani,  Prime Minister of Iraqi
     Kurdistan. As part of the ratification process,  WesternZagros worked with
     the KRG to  finalize  its EPSA area  boundary  and other key terms in line
     with draft petroleum  legislation.  The final EPSA area encompasses  2,120
     square  acres  (approximately  524,000  acres)  and holds a number of high
     potential exploratory prospects.

o    Western  completed  its first  winter  drilling  program  on our  operated
     in-situ  properties.  Results  from  the 13  core-holes  drilled  will  be
     analyzed  over  the  course  of  the  summer  by  both  Western   internal
     professionals  as  well  as  contracted  external   laboratory   agencies.
     Disclosure  of the resource  potential  together  with future  anticipated
     drilling  programs  will be announced  as details  become  known.  Not one
     recordable injury event occurred during the drilling  program,  reflecting
     Western's  emphasis on safe work  conditions  and  commitment to corporate
     social responsibility.

o    During the first quarter,  Western announced the appointment of Ms. Joanne
     L.  Alexander to the position of Vice President and General  Counsel.  Ms.
     Alexander  also  serves as  Corporate  Secretary  and as an Officer of the
     Company.

OPERATING RESULTS
- -------------------------------------------------------------------------------

Production

During the first  quarter of 2007,  Western's net bitumen  production  averaged
32,325  barrels per day, a 25 per cent increase over the 25,945 barrels per day
recorded in the first quarter of 2006.  Production in the first quarter of 2006
was impacted by the unplanned outage and subsequent replacement of the conveyor
belt at the Mine.  Compared to the fourth  quarter of 2006,  production  in the
first  quarter  of 2007 is  lower  due to  seasonal  conditions  which  present
additional operational challenges.

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

(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  March 31,  2007,  $0.1  million
     (Q1-2006  - $0.2  million)  has been  incurred  for  transportation  costs
     related to Oil Sands.

     Western  recorded  a 46 per cent  increase  in crude oil sales  revenue of
$304.3 million in the first quarter of 2007,  including $213.6 million from the
sale of proprietary production, compared to $207.8 million in the first quarter
of 2006, including $185.4 million from the sale of proprietary production. This
year-on-year  increase is predominantly  the result of increased  production in
the quarter  combined  with a higher  realized  selling  price per barrel,  the
latter being a function of a narrowing in the heavy crude oil  differential and
weakening of the Canadian dollar relative to the US dollar  partially offset by
lower underlying crude oil prices.




     Western  generated  net revenue of $179.2  million in the first quarter of
2007, after considering the impact of purchased  feedstocks and  transportation
costs downstream of Edmonton.  By comparison,  net revenue of $139.2million was
recorded  in the first  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 40,555 barrels per day in the first quarter of 2007 compared to 37,188
barrels per day in the first quarter of 2006.  This  represents a nine per cent
increase.

     During  the first  quarter  of 2007 WTI crude oil  averaged  US$58.16  per
barrel for the quarter,  a three per cent decrease  over the fourth  quarter of
2006 and an eight per cent decrease compared to the prior year period. Edmonton
PAR prices  averaged four per cent higher in the first quarter of 2007 compared
to the fourth  quarter of 2006,  primarily  due to the  weakening of the US/Cdn
dollar exchange rate. As Western measures its blended  differential to Edmonton
PAR, the weakening of the US/Cdn  exchange rate serves to improve overall sales
price realizations.

     Western's  realized  price  increased  to $58.49  per  barrel in the first
quarter of 2007  compared  to $55.31 per  barrel the prior year  period.  Sales
price  realizations  increased  by $3.41 per barrel from the fourth  quarter of
2006. The narrowing of the heavy crude oil differential in the first quarter of
2007  compared to both the prior year period and the fourth  quarter of 2006 is
largely  responsible  for the  improvement  in sales price  realizations.  This
narrowing of heavy crude oil  differentials is thought to be due in part by the
reversal  of crude oil  pipelines  into the US Midwest  and  Gulfcoast  regions
creating  incremental  demand for US refineries to process heavy Canadian crude
oil and unlock the value  inherent  in the heavy  crude oil  differential.  The
heavy crude oil  differential  averaged  $19 per barrel (33 per cent of WTI) in
the first quarter of 2007 compared to approximately $23 per barrel (38 per cent
of WTI) in the  fourth  quarter of 2006 and over $29 per barrel (46 per cent of
WTI) in the first quarter of 2006.  Other factors that  contributed to improved
sales price  realizations  were a general weakening of the US/Cdn exchange rate
over both of these comparable periods as well as local Alberta synthetic supply
constraints that placed additional demand on light synthetic crude oil which is
used by heavy oil producers to transport product to various markets. During the
first  quarter  of 2007,  the  light  to  heavy  crude  oil  sales  mix and the
corresponding  sales price realization  increased due to improvements  recently
introduced in the hydro-conversion process at the Upgrader.

OPERATING COSTS

Western's  unit cash operating  costs were $24.07 per processed  barrel for the
first  quarter of 2007  compared to $26.12 per  processed  barrel for the first
quarter of 2006 and $20.12 per processed barrel for the fourth quarter of 2006.
Compared to the first quarter of 2006, this decrease is largely attributable to
the 25 per cent  increase in production  which  provides  greater  economies of
scale over the cost structure  which is primarily fixed in nature together with
lower natural gas costs in the first quarter of 2007. This was partially offset
by minor repair costs  incurred  during the quarter  associated  with  seasonal
conditions.

     Compared to the fourth  quarter of 2006,  unit operating  costs  increased
$3.95 per  processed  barrel in the first  quarter of 2007.  This  increase was
largely due to  seasonal  factors  which  resulted  in  additional  repairs and
maintenance  impeding  performance  of some of the units,  particularly  at the
Mine.

(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 preceding 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 $1.2 million were  recorded in the first  quarter of 2007 compared
to $0.6  million  in the  first  quarter  of 2006.  Year-on-year  amounts  have
increased as a result of increased production and higher deemed bitumen royalty
prices.  Compared  to the fourth  quarter  of 2006,  royalty  expenditures  are
consistent as lower  production  volumes 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  AOSP,  together  with a return on
capital equal to the Government of Canada's federal  long-term bond rate. After
full 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.

     During the fourth quarter 2006, Western announced its participation in the
first  100,000  barrel  per day  expansion  of the AOSP and we fully  expect to
participate  in subsequent  mining  expansions  of the AOSP.  As such,  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. At current
commodity prices,  Western does not anticipate conversion to the 25 per cent of
net bitumen revenues for the next several years,  however, a temporary increase
to the higher  percentage may be incurred until applicable  government  rulings
can be completed with respect to AOSP Expansion 1. Incremental amounts incurred
during this interim period would be refundable.  The move to the higher royalty
rate may be  accelerated  or  postponed  depending  on future crude oil prices,
foreign exchange rates and the timing and inclusion of capital expenditures and
the Alberta government's treatment of bitumen extraction expansion efforts.




     The Alberta government has announced a review of the oil and gas royalties
including  oil sands.  A panel has been selected and public  consultation  will
occur over the coming months.  It is anticipated that  recommendations  will be
made  to  the  Minister  in  late  summer.  Western,   combined  with  industry
representation  through the Canadian Association of Petroleum Producers (CAPP),
will  actively  participate  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  $18.3 million in research,  business  development  and other
expenses  in  the  first  quarter  of  2007,  $5.9  million  of  which  relates
specifically to AOSP-related research and development  projects.  Also included
is Western's  share of a judgment  issued  against the Joint Venture Owners and
Albian Sands Energy in respect of a contractual  matter at the Mine.  The final
amount of the judgment, estimated at approximately $5.8 million net to Western,
has not yet been settled or paid.  Western and its other Joint  Venture  Owners
are  considering  whether  to  appeal  this  decision.  Net of  this  judgment,
research,  business  development  and  other  expenses  totaled  $12.5  million
compared to $6.0 million  recorded  for the prior year period.  The increase is
the result of additional efforts in research and business development involving
Western's Kurdistan and in-situ opportunities.

GENERAL AND ADMINISTRATIVE EXPENSE

General and  administrative  expenses  (OG&AO)  were $6.5 million for the first
quarter of 2007 compared to $8.9 million  (restated  for EIC-162  treatment for
stock  based  compensation)  for the first  quarter of 2006.  This  decrease is
largely due to the  retroactive  treatment for stock based  compensation  which
increased  first  quarter  2006  reported  G&A by  $5.0  million.  Net of  this
adjustment,  G&A was slightly  higher due to the increased  number of employees
within Western, together with additional consulting costs for various corporate
initiatives.

INSURANCE EXPENSE

Insurance  expenses were $4.0 million for the first quarter of 2007 compared to
$2.7  million in the first  quarter of 2006.  Insurance  expenses  were  higher
compared to the prior year period due to additional  premiums  associated  with
increased  levels of coverage  combined with a weakening 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 first quarter of 2007, financing charges totaled $14.6 million, $5.6
million of which was  capitalized  relating to AOSP  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 AOSP
Expansion  1. This  represents  a  moderate  increase  from the  $13.0  million
incurred for financing  charges in the first quarter of 2006.  Interest expense
for the  three  months  ended  March 31,  2007 is  comprised  of $12.6  million
(Q1-2006 - $11.3 million) related to interest charges on debt obligations, $0.6
million  (Q1-2006 - $0.7  million) on capital lease  obligations,  $0.7 million
(Q1-2006 - $1.0  million)  on the option  premium  liability  and $0.7  million
(Q1-2006 - 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  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 12 per cent increase in total
interest  expense  compared  to the first  quarter of 2006 is a function of two
items: 1) Western  carrying  larger  balances in its Revolving  Credit Facility
associated with funding our share of the AOSP Expansion 1 capital costs, and 2)



the weakening of the US/Cdn exchange rate thereby  increasing  interest charges
on our US denominated  Notes (reported in Canadian  dollars).  Interest expense
increased by $0.9 million in the first  quarter of 2007  compared to the fourth
quarter  of 2006 as well due to higher  levels of debt and a  weakening  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 funding
requirements as part of our normal course business model.

DEPRECIATION, DEPLETION AND AMORTIZATION

Depreciation, depletion and amortization (ODD&AO) totaled $13.1 million for the
first  quarter of 2007  compared to $10.5 million in the first quarter of 2006.
Higher amounts are recorded over the prior year period due to increased  levels
of production.  Incremental  reserves associated with AOSP Expansion 1 will not
be  included in the  depreciation  rate until the assets  associated  with AOSP
Expansion 1 commence operations, anticipated in 2010.

FOREIGN EXCHANGE

During the first quarter of 2007,  Western  reported a foreign exchange gain of
$5.8 million  compared to a loss of $0.4 million in the first  quarter of 2006.
This gain is the result of a stronger month-end Canadian dollar relative to the
US dollar compared to the previous quarter's  month-end rate which results in a
lower Canadian equivalent amount on Western's US$450 million long-term debt and
deferred option premium  liability.  As reference points,  the noon-day foreign
exchange rate on March 31, 2007 was $0.8674  US/Cdn  compared to $0.8581 US/Cdn
on December 31, 2006 and $0.8568 US/Cdn on March 31, 2006. The average rate for
the first  quarter of 2007 was $0.8537  US/Cdn  compared to $0. 8659 US/Cdn for
the prior year period and $0.8784 US/Cdn for the fourth quarter of 2006.

RISK MANAGEMENT ACTIVITIES

Western  began to realize the benefits and  associated  costs of the  strategic
crude  oil  hedging  program  executed  in the  third  quarter  of  2005 in its
financial  statements.  Premiums associated with the program were funded out of
cash flow from operations due to Western's  decision to defer the premiums.  In
January  2007,  a number of  Western's  US$55 per  barrel put  options  settled
in-the-money for Western as WTI averaged US$54.35 per barrel for the month. The
$0.1 million  settlement was recorded as a realized risk management gain on our
income  statement.  WTI continues to trade within the band  established  by the
collar which is 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 December 2009.



     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, 2007,  Western's  risk
management assets decreased  significantly in value from the amount recorded as
at December 31, 2006 resulting in a mark-to-market loss of $19.0 million ($15.1
million  net of tax)  primarily  due to the  moderate  weakening  in WTI prices
during the quarter together with less time value associated with the options as
they  approach  maturity.  This  loss  does not  impact  stated  cash flow from
operations.

INCOME TAXES

For the first  quarter  of 2007,  Western  had an income  tax  expense of $11.8
million  compared to an income tax recovery of $9.9 million for the same period
last year.  The recovery in the first  quarter of 2006 largely  resulted from a
risk  management  loss  whereas the  expense  for the first  quarter of 2007 is
largely  the result of  increased  profitability  due to  increased  production
levels and higher sales price realizations.

     During the first  quarter of 2007,  the Federal  Government  announced its
intention to phase out the  Accelerated  Capital Cost  Allowance  (OACCAO) that
permitted oil sands  companies to claim a higher amount against  taxable income
than normally  permitted  for assets of this nature.  As it relates to the AOSP
and Western  specifically,  it is currently  envisioned that capital associated
with  Expansion  2 and beyond  will not be  eligible  for ACCA,  however,  base
operations  and AOSP Expansion 1 capital 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.  Such a change in corporate tax rules will not have
a material impact on Western's reported earnings and cash flow from operations.

NET EARNINGS

During the first quarter of 2007,  Western reported net income of $31.6 million
($0.20 per share) compared to a net loss of $24.8 million (restated) ($0.15 per
share) in the first quarter of 2006.  Net earnings in the first quarter of 2007
includes the impact of $19.2 million  ($15.3  million net of tax) in unrealized
risk  management  losses,  $6.3 million ($4.3 million net of tax) in unrealized
foreign  exchange  gains on our US dollar  denominated  debt and option premium
liability and $5.8 million related to Western's  share of the judgment  against
the AOSP Owners and Albian Sands Energy.

first quarter of 2007, reflecting a 31 per cent increase over the $62.1 million
recorded  for  the  first  quarter  of 2006  due in  large  part  to  increased
production  and higher  sales price  realizations.  First  quarter 2007 EBITDAX
decreased  $18.5 million  compared to the fourth quarter of 2006. This decrease
in EBITDAX is the result of lower  production  stemming  from  seasonal  issues
partially offset by higher sale price realizations.

     Cash flow from  operations  before  changes in  non-cash  working  capital
(Ocash flow from  operationsO)  was $63.0 million for the first quarter of 2007
compared to $47.8 million in the first quarter of 2006. First quarter 2007 cash
flow from  operations  decreased $28.1 million over the fourth quarter of 2006.
This  decrease is primarily 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 2007,  Western drew an additional $52 million under
its $340 million Revolving Credit Facility  bringing the amount  outstanding to
$129  million  as at March 31,  2007.  Additional  amounts  drawn  were used to
partially fund Western's share of capital  expenditures  for Expansion 1 during
the quarter. As at March31,  2007, the undrawn capacity of the Revolving Credit
Facility  equated  to $194  million,  net of  amounts  allocated  to letters of
credit.

     Western's  debt to total  capitalization  as at March  31,  2007  remained
relatively unchanged at 49 per cent compared to the prior year period and as at
December 31, 2006. Western  anticipates the extent of leverage will increase as
Western  continues  to  fund  its  share  of  capital   expenditures  for  AOSP
Expansion1, together with Western-led initiatives through a combination of cash
flow from operations and incremental borrowings.

CAPITAL EXPENDITURES

Western's capital  expenditures  totaled $160.5 million in the first quarter of
2007  compared to $35.3  million  for the  comparable  period in 2006.  Capital
expenditures  in the first  quarter of 2007  included  $10.5  million  for base
operations,  $4.6 million for sustaining capital,  $114.4 million for expansion
related  capital  including  capitalized  interest,  $8.3  million  related  to
Western's Kurdistan  initiative and $22.7 million for business  development and
corporate  expenditures largely consisting of in-situ winter core-hole drilling
programs for both Western  operated lands and Western's 20 per cent interest in
Chevron's Ells River In-situ Project.

ANALYSIS OF CASH RESOURCES

Cash balances  totaled $5.5 million at March 31, 2007 compared to $15.7 million
at March 31,  2006.  Cash  inflows  included:  $63.0  million in cash flow from
operations,  $52.0  million from  Revolving  Credit  Facility  drawdowns,  $1.3
million  from the  exercise  of  employee  stock  options  and a $46.9  million
decrease  in  non-cash  working  capital.   Cash  outflows  included:   capital
expenditures of $160.5 million and $0.3 million  repayment of obligations under
capital lease.

     During the first quarter of 2007, the decrease in non-cash working capital
was the  result of a  $5.6million  decrease  in  accounts  receivable,  a $45.3
million  increase in accounts  payable and a $3.2  million  decrease in prepaid
expenses,  offset by a $7.2  million  increase in  inventory.  The  decrease in
accounts  receivable is the result of decreased sales volumes stemming from the
lower  production in 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 the construction of AOSP Expansion 1. Inventory
was 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 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 this year.  Amounts owing under all
Western's insurance claims total $244 million as of March 31, 2007.




FLOW-THROUGH SHARES

As  communicated  during 2006, the Canada  Revenue  Agency (OCRAO)  proposed to
challenge the characterization of certain expenditures  capitalized as Canadian
Exploration  Expense (OCEEO) 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  continues  to  focus  on the  four key  initiatives  which  drive  the
Company's  growth  strategy  -  the  AOSP,  in-situ   development,   downstream
integration,  and  the  Kurdistan  oil  opportunity  through  our  wholly-owned
subsidiary   WesternZagros  Limited.  Western  is  working  diligently  on  the
execution of these  initiatives and believes that significant  long-term growth
potential  lies ahead of us as we  continue  on our path of adding  significant
value for all our  stakeholders.  Western  anticipates  its share of production
from the AOSP to  average  approximately  33,000 to 35,000  barrels  per day in
2007, unchanged from prior guidance.

     Through both mining and in-situ development,  Western's production profile
could  exceed  200,000  barrels per day in the next 15 to 20 years.  Given this
profile,  Western continues to pursue downstream  integration  opportunities to
maximize value from our oil sands resources and undeveloped  acreage  position.
Related to these initiatives,  Western announced that it intends to explore and
pursue  opportunities that will realize the full value of its assets and future
growth potential.  This may result in an acquisition or sale of assets,  merger
or other corporate transaction. 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.  This committee's role is
to direct  the scope of work  activities,  advise the Board of  Directors  on a
timely and regular basis and to make recommendations to the Board of Directors.
While  we  are   encouraged   with  the  number  and   quality  of   attractive
opportunities,  as a matter of policy,  Western  does not discuss any  specific
business  opportunity  until such time as it has been fully  considered,  it is
material  and it becomes a  disclosable  event.  In  addition,  there can be no
assurances that any of these  activities will result in the  consummation of an
agreement or transaction or result in any change to Western's  current  ongoing
business strategy.

AOSP EXPANSION 1 UPDATE

Construction and engineering  activity is progressing  rapidly at both the mine
site and the upgrader with a combined work force of over 3,000 personnel. Field
construction  progress  includes the completion of the primary  separation cell
piling work, continued progress with respect to the deep underground facilities
and building foundations in extraction and tailings,  continued  advancement on
the Albian Village in support of first phase occupancy,  headway on the potable
water and sewage  treatment  plants.  Detailed  modules  fabrication  and field
construction  schedules  continue to be refined for the mine site,  with module
fabrication  scheduled  to begin in  mid-2007.  At the  upgrader,  activity has
focused on the  construction  of the dilbit tank, the winter piling program and
installation of deep underground  piping.  Approximately four million man-hours
have been recorded thus far without a lost-time  incident.  Overall progress is
on plan with respect to both cost and schedule.




     With respect to Expansion 1, capital expenditures are expected to continue
to grow  over the next  couple  of years  as  development  efforts  accelerate.
Western plans to implement a comprehensive  financing  plan,  comprised of cash
flow from  operations and  incremental  borrowings,  to provide the platform by
which we will meet our financials 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 (OEBITDAXO), 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  prices,  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  (OGAAPO).  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 ended December 31, 2006,  Western  retroactively  adopted Emerging
Issues  Committee  Abstract  162  (OEIC-162O).   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 month  period  ended March 31,
2006 was  increased  by $3.2  million,  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 OFinancial
Instruments -  Recognition  and  Measurement,O  3862  OFinancial  Instruments -
Disclosures,O 3863 OFinancial  Instruments - Presentation,O 3865 OHedges,O 1530
OComprehensive  Income,O and 3251  OEquity.O  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.

     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 March 31,  2007,  $0.7 million of these costs
were included in interest expense under the effective interest method.

HEDGES

Section 3865 replaces the guidance formerly in Section 1650,  OForeign Currency
TranslationO and Accounting Guideline 13, OHedging RelationshipsO by specifying
how hedge  accounting is applied and what  disclosures are necessary when it is
applied.  Western  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
(OOCIO).  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 had no such  transactions  and events which would  require the
disclosure of OCI for the three month period ended March 31, 2007.  Any changes
in these items would be presented in a consolidated  statement of comprehensive
income.

EQUITY

Section 3251 replaces Section 3250, OSurplusO and establishes standards for the
presentation  of equity  and  changes  in  equity  during a  reporting  period,
including  changes in  Accumulated  Other  Comprehensive  Income  (OAccumulated
OCIO).  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,  OAccounting
ChangesO, which revises and replaces former Section 1506, OAccounting ChangesO.
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
Abstract  163,  ODetermining  the  Variability  to be  Considered  in  Applying
AcG-15O,  which addresses how an enterprise should determine the variability to
be  considered  in  applying  AcG-15,   OConsolidation   of  Variable  Interest
EntitiesO.  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  OCorporationO),  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 Note
1(b). 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  December31,  2006, the  Corporation  retroactively  adopted
Emerging  Issues  Committee  Abstract  162  (OEIC-162O).  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 month period ended
March  31,  2006  was  increased  by $3.2  million,  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
OFinancial   Instruments  -  Recognition  and  Measurement,O   3862  OFinancial
Instruments - Disclosures,O 3863 OFinancial  Instruments - Presentation,O  3865
OHedges,O 1530 OComprehensive Income,O and 3251 OEquity.O 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,  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 March 31,  2007,  $0.7 million of these costs
were included in interest expense under the effective interest method.

     Hedges

Section 3865 replaces the guidance formerly in Section 1650,  OForeign Currency
TranslationO and Accounting Guideline 13, OHedging RelationshipsO 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
(OOCIO).  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 had no such transactions and events which would require
the  disclosure  of OCI for the three month period  ended March 31,  2007.  Any
changes in these  items  would be  presented  in a  consolidated  statement  of
comprehensive income.

     Equity

Section 3251 replaces Section 3250, OSurplusO and establishes standards for the
presentation  of equity  and  changes  in  equity  during a  reporting  period,
including  changes in  Accumulated  Other  Comprehensive  Income  (OAccumulated
OCIO).  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, OAccounting ChangesO,  which revises and replaces former
Section  1506,  OAccounting  ChangesO.  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,  ODetermining the Variability to be Considered in Applying
AcG-15O,  which addresses how an enterprise should determine the variability to
be  considered  in  applying  AcG-15,   OConsolidation   of  Variable  Interest
EntitiesO.  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 March 31, 2007, costs not currently  subject to depreciation,  depletion and
amortization  included  $340.0  million  relating  to the  Athabasca  Oil Sands
Project  (OAOSPO)  Expansion  as it has not been  substantially  completed  and
commercial  production  has not yet  commenced.  During the three month  period
ended March 31,  2007,  the  Corporation  capitalized  $5.6 million in interest
costs relating to this Expansion. As at March 31, 2007, a total of $8.4 million
of interest costs has been capitalized relating to this Expansion.

All  costs  included  in the  Kurdistan  Exploration  Project  and the  In-Situ
Projects  are  excluded  from  depletion  as they  represent  costs  related to
properties  incurred  in  cost  centres  that  are  considered  to  be  in  the
pre-production  stage.  Currently,  there are no proved  reserves in these cost
centres. All costs, net of any associated revenues,  in these cost centres have
been capitalized.



Note 3. Long-term Debt

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


The Corporation's US dollar  denominated Senior Secured Notes (the ONotesO) are
translated  into Canadian  dollars at the period end exchange rate. As at March
31, 2007, US$11.6 million of unamortized  transactions costs are netted against
the Notes.  During the three month  period  ended March 31,  2007,  transaction
costs of $0.7  million  have been  recognized  as  interest  expense  under the
effective interest method.

For the three  month  period  ended  March 31,  2007,  the  unrealized  foreign
exchange  gain  arising on the Notes was $5.4  million  (March 31,  2006 - $0.5
million). As at March 31, 2007, a total of $189.9 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.


Note 4. Lease Obligations

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

The  Obligations  Under  Capital Lease  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 fully repaid.

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 month period ended March 31,
2007, no payments were made in regard to this obligation (March 31, 2006 - $0.2
million).


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 month period ended March31,
2007,  $6.3  million  was  paid in  respect  to the  settlement  of the  option
contracts maturing during the period (March31, 2006 - nil). The remaining total
net premiums  payable by the  Corporation are US$16.5 million for the remainder
of 2007, US$32.4million 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 month  period  ended March 31, 2007 was $0.7  million
(March 31, 2006 - $1.0 million). 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 month  period  ended  March31,  2007 was $0.9  million
(March 31, 2007 - $0.1 million unrealized foreign exchange loss).

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

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 9. Net Earnings Per Share
- -------------------------------------------------------------------------------

Basic weighted average number of common shares for the three month period ended
March 31, 2007 was 161,493,276 (March 31, 2006 - 160,568,322). Diluted weighted
average  number of shares for the three month  period  ended March 31, 2007 was
163,155,850.  Due to a loss for the three month period ended March 31, 2006, no



incremental  shares were included in the diluted  earnings per weighted average
number because the effect would have been anti-dilutive.


Note 10. Stock-based Compensation
- -------------------------------------------------------------------------------

a)   Stock  Option  Plan Under the  Corporation's  Stock  Option  Plan,  83,860
options were  granted  during the three month period ended March 31, 2007 at an
average exercise price of $33.72 per share (March 31, 2006 - 787,540 options at
an average exercise price of $33.62 per share).  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  weighted-average  fair values of the
options and the assumptions used in their determination are as follows:

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 March 31, 2007,  the  Corporation  had the following put and call options
outstanding:

                                            2007         2008          2009
- -------------------------------------------------------------------------------

Barrels Per Day
   Put Options Purchased                  20,000       20,000        20,000
   Call Options Sold                      10,000       15,000        15,000

   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:

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.

ratified by the  Kurdistan  Regional  Government  ("KRG") and  confirmed by His
Excellency Nerchivan Barzani, Prime Minister of Iraqi Kurdistan. As part of the
ratification  process,  WesternZagros  worked with the KRG to finalize its EPSA
area boundary and other key terms in line with draft petroleum legislation. The
final EPSA area  encompasses  2,120 square  kilometers  (approximately  524,000
acres) and holds a number of high  potential  prospects.  The EPSA provides for
the exploration of conventional  oil and gas in the Federal Region of Kurdistan
in northern Iraq and a work program.

b)   Contingencies

During the three month  period  ended  March 31,  2007,  a judgment  was issued
against  the Joint  Venture  Owners  and  Albian  Sands  Energy in respect of a
contractual matter.  While the final amount under the judgment has not yet been
settled or paid, the  Corporation  has recognized $5.8 million as its 20% share
in OResearch,  Business Development and OtherO of the Consolidated Statement of
Operations.  The  Corporation  is  considering  whether  it  will  appeal  this
decision.   Other  than  this  judgment,  the  Corporation  believes  that  any
liabilities  that might arise  pertaining  to similar  matters would not have a
material effect on its consolidated financial position.
