SUPPLEMENTARY OIL & GAS INFORMATION (UNAUDITED)

with the  United  States  FAS 69,  "Disclosures  about  Oil and Gas  Producing
Activities",  and where  applicable  is  reconciled  to the US GAAP  financial
information.

NET PROVED OIL AND NATURAL GAS RESERVES

The Company retains qualified  independent reserves evaluators to evaluate the
Company's proved oil and natural gas reserves.

     o   For the  year  ended  December  31,  2005,  the  reports  by  Sproule
         Associates  Limited  ("Sproule") and Ryder Scott Company covered 100%
         of the Company's conventional reserves;

     o   For the year ended  December  31,  2004,  the  reports by Sproule and
         Ryder  Scott  Company  covered  100%  of the  Company's  conventional
         reserves;

     o   For the year ended December 31, 2003, the reports by Sproule  covered
         100% of the Company's conventional reserves; and

     o   For the year ended December 31, 2002, the reports by Sproule  covered
         89% of the Company's conventional reserves.

Proved oil and natural  gas  reserves  are the  estimated  quantities  of oil,
natural gas and  natural gas liquids  that  geological  and  engineering  data
demonstrate  with reasonable  certainty to be recoverable in future years from
known  reservoirs  under existing  economic and operating  conditions.  Proved
developed  reserves  are reserves  that can be expected to be  recovered  from
existing wells with existing equipment and operating methods.

Estimates of oil and natural gas reserves are subject to uncertainty  and will
change as additional  information  regarding  producing  fields and technology
becomes available and as future economic and operating conditions change.

The  following  table  summarizes  the Company's  proved and proved  developed
conventional  crude oil and  natural gas  reserves,  net of  royalties,  as at
December 31, 2005, 2004 and 2003:

STANDARDIZED  MEASURE OF DISCOUNTED  FUTURE NET CASH FLOWS FROM PROVED OIL AND
NATURAL GAS RESERVES AND CHANGES THEREIN

The following  standardized  measure of discounted  future net cash flows from
proved oil and natural gas reserves has been  computed  using  year-end  sales
prices and costs and year-end statutory income tax rates. A discount factor of
10% has been applied in  determining  the  standardized  measure of discounted
future net cash flows.  The Company  does not  believe  that the  standardized
measure of discounted  future net cash flows will be  representative of actual
future net cash flows and should not be considered to represent the fair value
of the oil and natural gas properties.  Actual net cash flows will differ from
the  presented  estimated  future  net  cash  flows  due  to  several  factors
including:

     o    Future  production  will  include  production  not only from  proved
          properties,  but may  also  include  production  from  probable  and
          potential reserves;
     o    Future production of oil and natural gas from proved properties will
          differ from reserves estimated;
     o    Future production rates will vary from those estimated;
     o    Future rather than year-end sales prices and costs will apply;
     o    Economic   factors  such  as  interest  rates,   income  tax  rates,
          regulatory and fiscal  environments  and operating  conditions  will
          change;
     o    Future  estimated  income taxes do not take into account the effects
          of future exploration expenditures; and
     o    Future development and site restoration costs will differ from those
          estimated.

Future net revenues,  development,  production and restoration costs have been
based upon the estimates referred to above. The following tables summarize the
Company's  future  net cash  flows  relating  to proved  oil and  natural  gas
reserves based on the standardized measure as prescribed in FAS 69:
