                SUPPLEMENTARY OIL & GAS INFORMATION (UNAUDITED)


This  supplementary  crude  oil and  natural  gas  information  is  provided  in
accordance  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 CRUDE OIL AND NATURAL GAS RESERVES

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

     o    For the years ended  December 31, 2006,  2005, and 2004 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, 2003,  the reports by Sproule  covered
          100% of the Company's conventional reserves.

Proved crude oil and natural gas reserves are the estimated  quantities of crude
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 crude 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, 2006, 2005, 2004 and 2003:

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

The  following  standardized  measure of  discounted  future net cash flows from
proved crude 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 crude 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 crude 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 asset retirement  obligations 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  crude oil and natural gas
reserves based on the standardized measure as prescribed in FAS 69:
